Amy was pretty nervous, fidgeting in her seat as the clinical walls were all she could see - polished, clean white mixing with a few notice boards full of stuff she didn’t really understand, advertising all sorts of different medicines and treatments. Her tail flicked about a little, even as she tried to keep it under control. She could feel her fur prickling slightly too, though she really didn’t know why.

It was only a doctor's visit! Sure, she’d never really been to them often… at 12 years old, she hadn’t gotten sick as far as she could remember, nor ever injured herself enough to warrant a visit. Not like some of the boys in her class - Danny, a fellow wolf (though he was red, compared to her grey), had broken his arm once whilst playing some sort of sport. When he finally came back to class, his arm was in this big blue cast - which she’d signed, along with the rest of her class.

That had been a while ago, and he was all better now. Doctors did good things, made sure you were safe and healthy. So why was she being anxious? Amy kept trying to tell herself off in her head, taking a deeper, slower breath. Maybe it was just because she was worried that something *was* wrong with her. She always did her best to keep clean, brush her teeth, eat healthily… but what if she’d missed something or done something wrong?

At least her dad was here. He was browsing something on his phone while waiting, but just looking up at him made her feel more safe. He’d already told her what to do - be honest with the doctor if he asked any questions, make sure to listen to him if he asks her to do anything, and of course be polite. Unfortunately, this was a one to one session - meaning she had to do it alone. 

Amy had mixed feelings about that. Sure, she wanted to prove to her dad that she was strong and independent - she was 12, after all… not a little cub anymore! But… still, it was a little nerve wracking! Anyway, this was taking forever, they’d been waiting for about 15 minutes now…

“Amy? Doctor Stedman will see you now.”

Oh. There it was. A pretty looking nurse was looking around the mostly empty waiting room… well, she was actually looking directly at her. She was the only girl young enough to fit the description - 12, grey wolf, with her father. The other patients waiting around for the doctor were an old couple of rabbits in the corner, their fur grey and raggedy, as well as a fox female with a very large belly. Amy had stared at it when they first entered the waiting room, curious why her tummy was so… round.

“Go on Amy, I’ll be right here when you’re done.” Her father prompted her, giving her a slight nudge with a paw. Amy’s heart began to beat a little faster as she nodded and got to her foot paws… moving closer to the nurse, looking up at her nice warm smile…

It was a really nice smile to be fair. Disarming, in fact - Amy felt herself calm down considerably as the nurse reached out a paw for her to hold onto. She took it, even though in the back of her mind she thought it was a little embarrassing… but there was nobody around to make fun of her, so she didn’t mind. She probably wouldn’t have taken her paw if her older brother was here, but he’d been allowed to stay at home to look after the house while they were out.

The nurse led Amy down a hallway, while the little wolf cub looked at some of the name plates on the doors. Naturally, she was curious about everything, though of course there wasn’t much of interest yet. A few seconds later, the nurse knocked on a door - and with a confirmation in the form of: “Come in!” from inside, she opened it up and led Amy inside.

Now there was much more to see in here! This was a proper doctors office, with cabinets full of… presumably medicine, an examination bed with privacy curtains, a desk with office stuff… and the doctor himself! He was sat at the desk and turned a big beaming smile on Amy as she entered, which she did her best to return - feeling herself warm up inside! The nurse let go of her paw before shutting the door behind her, leaving Amy and the doctor together in the office. Amy noticed some weird foam looking stuff on the door, and her gaze lingered…

“Ah, that’s soundproofing! It’s used to keep sounds inside of the office, rather than being heard outside. Did you hear anything from the other offices you passed?” The doctor asked, noting her interest. Amy shook her head, assuming the other offices were the doors she passed along the way.

“Great! Glad to hear they’re working. Now, why don’t you take a seat Amy. Right here will do!” he pointed out a chair in front of him, watching as Amy took a seat. She looked up at him, really taking the time to check him out!

Her nose immediately notified her that he was also a canine - a wolf, but she didn’t know what type. His fur had a lot of different colours ranging from black, grey and white. He was very pretty though, and her eyes couldn’t really seem to take themselves away from his muzzle. His ears were twitching slightly too, but she couldn’t tell why.

Dr Stedman, however, was amused.

Amused at the cute little cub that had just entered his office. She’s very obviously new to the whole “doctors appointment” thing, with the way she looked about at everything in that cub-like awe. It was extremely adorable, and was making his knotted cock pulsate slightly… he always loved the ones that were innocent. Cute, innocent and naive.

“Amy? Are you doing okay?” He asked her, putting a lot of soft emphasis into his sentence - which caused the little wolf pup to snap back to real reality. She nodded, her cheeks flushing slightly as she hoped that she hadn’t done anything embarrassing. “Mhm! I’m okay! I just… uhm… don’t really know what to… do?” she asked, unsure of what words to use, hoping she doesn’t sound too silly.

The doctor smiled at her, before extending a paw for a pawshake. “Well, introductions will do nicely first - as I’ll likely be your doctor for the rest of my career, or until you move away that is. I’m Adrian Stedman… but that’s a bit too formal. You can call me Andy, if you’d like.”

Amy took his paw happily and gave it a little shake, opening up her maw to introduce herself back: “H-hello Andy! I’m Amy-” but he put up a finger, shushing her. She tilted her head a little in confusion, before he elaborated… “I already know who you are, Amy! Your father provided all the required information when signing you up to our practice. So you’re in our system, now. The system also tells me you’ve never been to a doctor for a proper check-up yet, is that true?”

Amy nodded, squeezing her chair slightly as she looked up at Doctor Stedman. “Yes, that’s true! I haven’t gotten sick or injured myself badly. I’ve only had a few bruises or cuts before, but those are rare. This is my first time going for a proper… doctor's visit.” She confirmed, much to Andy’s delight. Gosh she is just SO cute!

“Well it’s lovely to have you for your first time, Amy! Let’s start with some basic tests first, then. Blood pressure, heartbeat, that sort of thing.” He gently grasped a nearby blood pressure monitor and hooked it up to her. Amy remained still and let him work, unsure what exactly the monitor would… do.

Andy was taking it slow for now, but he couldn’t really resist this adorable little cub for long. While the monitor did its thing, he turned to her to ask a few questions.

“So Amy, you’re 12 - almost 13! Are you excited to be a teenager in… what was it…” He trailed off, looking at her to finish for him - which she actually managed to pick up, giving a small smile and finishing the sentence: “4 months!” Andy gave a little small clap with a smirk, congratulating her.

“Wow, that’s awesome! Well done Amy… so, are you excited?” he asked, and Amy thought for a moment… actually, not really. She knew the answer. “Yeah! Then nobody will get to call me a little cub anymore - I’ll be a teenager!” she squeaked, her voice raising a little higher. She was so utterly adorable, Andy’s pants were getting quite tight…

“That’s lovely to hear. Have you started puberty yet, Amy?” he asked, slipping in a normal question for her age bracket. Mostly. Amy paused for a moment, her eyes looking a little worried… before she had to admit to him: “Uhm… I don’t know what that is? Is that like a school thing?”

Andy paused for a moment, thinking things through. This was an absolutely golden opportunity - his absolute favourite type of cub had wandered straight through his office door and landed right on his lap. Well, soon… hopefully. In fact, this little dummy whore was one of the absolute best little cockteases he’d ever met! Most girls already knew enough about sex to pretty quickly identify the swelling in his pants, to spread their legs and let him examine their clits and cunts, to allow him to measure their fertility levels…

By pumping puppy after puppy into them, of course. How else would a professional get to work? He’d lost count years ago of the amount of times his fat, fuzzy cumtanks had unloaded into a young breeding hole. Girl after girl… and soon, daughter after daughter. Working this job over the years, he’d gotten some great patient to doctor relationships going… and he’d gotten to have his own daughters come to him for their annual checkups too.

And then they left with a wombful of daddy's puppies… and so the cycle kept going, and going~

At least not too many girls had requested condoms. Sometimes he could convince them to drop it, or sneakily slice through the pathetically weak material with a claw… thank fluff that condom companies knew their target audience, and made the things break so easily! Worst of all was the fertility blockers - they actually worked, and they worked well. He’d petitioned numerous times to have the horrible things banned nationwide, and although he was successful in keeping them out of his practice… sometimes a girl turned up who’d gotten them elsewhere. Ugh..

There was nothing better than knocking up a cub. But it felt so fucking good to con them into it too! Most of the girls were born sluts, bending over the moment he asked - but this little one, Amy? She was special - joining a very, very small group of special cubs over the years. A group of oblivious, naive little toys who he could mold and guide with his paws and balls.

And now? Sitting before him, the most prime breeding stock he’d likely ever find? He couldn’t pass this up - but he had to make sure to properly reel her in. No scaring her off too soon…

“No, it’s not a school thing. Well, I guess it could be… depends on your school, Amy! But don’t worry - you’ll learn about it in time. I’m not really qualified enough to tell you all about it, but when you encounter puberty… you’ll know! That’s all I can say for now, sorry sweetheart. Do you understand?” he asked, leaning a little closer to her as his nose twitched from her delightful scent.

She didn’t.

Not really. Sure, she understood his words - mostly. But the broader meaning was a little lost on her. She nodded slowly, trying to get an answer in quick before it was obvious she had no proper clue what he actually meant. Then she brought up her paw slowly, unfurling her fingers… “So it’s… something I’ll learn about later?” She asked with a cute questioning tone.

Doctor Stedman gave her a double thumbs up, much to her relief. He swivelled on his chair and grasped a stethoscope before presenting it to her, asking: “So Amy, you seem like a smart girl - know what this is?”

Amy’s tail wriggled slightly at the compliment - one that she wasn’t used to getting. Her grades were average enough, but none of her peers had ever described her as “smart”. In fact, behind her back and without her knowledge, they frequently gossiped about her being a silly airhead. Thankfully said gossip hadn’t gotten back to her and upset her… yet. But, in this case, she did know what the doctor was presenting!

“A heart listening thing! It’s the uh… Steth…scope?” she almost got the entire word right, and Andy quickly helped correct her: “Wow Amy, you really are a smart cookie! You could be a doctor too one day - I’m really proud of you! Though, you missed an ‘o’ it’s steth-O-scope! Do you know how they work?”

Amy nodded quickly and pressed a finger into her shirt - though missing her heart, just randomly feeling around the fabric. “You gotta press it on me and, uhm… well, listen!” she says, smiling as Andy gave her a satisfied nod. “That’s right, good girl Amy! Though, I can’t exactly listen to your heart through fabric, can I?” he prompted her, curious to see what she’d do.

He didn’t have to wait long.

Amy’s ears twitched as she listened, before she looked down at her shirt - and grabbed the bottom, lifting it all the way up! She didn’t take it off - but she held it up by her neck, exposing… everything. Her belly, her chest… and her adorable little titties! Her fur wasn’t bristling in embarrassment or fright - she was… relaxed, exposing her cute little nipples and tits to the doctor! She wasn’t wearing a bra, something Andy filed away as a personal note… before he brought his paws closer to her chest, not wanting to invite any suspicion by waiting too long.

“Alrighty, let’s see where the best spot is…” he murmured to her, as his paws made contact with her tits. He wanted to see how much he could push this - really get a good feel of how much she would be able to take without questions. His cock was straining inside his pants as he ran his fingers over her little nipples, grinding them softly as his paws squeezed the adorable little mounds on her chest! He licked his lips softly and looked up at her to see if she was concerned - but… nothing. Amy seemed totally chill.

He brought up the stethoscope and pressed it into her breast, making sure to pretend to listen intently whilst his fingers caressed her nipples continually. They were already hardening up from his touch, much to his satisfaction of course, but he was curious if she actually knew why. The doctor's ears twitched as he caught a soft exhale from Amy, but she didn’t bring anything up - and he was more than content not to bring any attention to his actions… aiming to preserve her seemingly innocent nature.

After about a minute of shamelessly rubbing a little wolf cubs tits and nipples, he withdrew the stethoscope with a smile and a nod: “Everything sounds good to me under there! Well done Amy, you’re a very good girl. How did that feel? I hope it wasn’t uncomfortable…” he trailed off a little, giving her a mock glance of pity. Amy shook her head quickly, rapidly confirming: “Oh no, it actually felt really… uhm… nice! Thank you Dr Stedman- or, uh, Andy!”

Aw. How cute. But what else could he get away with?

“Amy, could you stand up for me please? I need to take a good look at your lower half - legs, thighs, butt. Those sorts of areas.” He purposefully mentioned her ass there to see if it would trigger any sort of response from her - some shyness perhaps, or general protectiveness of her… special zones.

But… nothing. Amy got to her feet and moved closer, unsure really what to do - until Doctor Stedman got up too, patting her shoulder for a moment before getting onto his knees… running his paws up and down her legs for a moment, peering closely at her fur. She didn’t  seem to mind - not even when his grasp rose up to her thighs, squeezing gently… then a little harder. His eyes kept flashing upwards up her skirt to admire the fantastic view… she was wearing black panties, simple - but tight.

Very tight, in fact. The camel toe was making him drool… and he quickly glanced up at her to see if she looked concerned, but Amy was just idly looking around the room - even as the doctor's paw grasped her skirt and lifted it gently, showing off her entire rear end to his face. His other paw delicately rubbed itself over her pantie-clad rump, giving it a gentle squeeze and a wobble - but still! Nothing!

He could feel his resolve slipping away in large chunks… It was now or never.

“Okay, Amy… could you take a seat on the bed for me, please?” he asked her, pointing at the examination bed. She nodded and moved over, plopping her surprisingly plump rump down onto the bed and looking at Andy quizzically whilst he rose to his feetpaws.

He cleared his throat and put on a soft, concerned voice - or at least, as much as he could manage. He was painfully aware of how tight his pants were, and how much of a large erection was visible…

“Amy… I’m… well, I’m sorry to say but I have identified a pretty significant problem. Now, please don’t panic or worry - it’s nothing too, uh… dangerous. Yet, at least. But… from what I can see and feel, you aren’t pregnant.”

Both of them looked at each other for a moment, Andy with a concerned look - Amy, confused… and scared.

“I… I don’t… I don’t know what that means. Is that bad? Is it like an infection? Am I contagious??” she started rapid-firing questions after a few seconds, causing Doctor Stedman to raise up his paw to keep her quiet. He moved closer, gently rubbing the top of her head and fluffy ears.

“It’s bad, sort of. You’ll be immediately okay for now - but over time, you’ll get worse unfortunately. No, you’re not contagious, don’t worry about that. It’s… not really an infection, more like a growth. But, Amy? Look at me.” He ordered, gently raising her chin up so he could look her right in the eyes.

“I know it might be scary to hear, Amy - but listen to me, you’ll be fine. Not being pregnant actually has a cure, something I can give to you right now in fact! I’m able to give you a very special injection, and it’ll make sure you get pregnant, okay? So, don’t worry. You okay sweetheart?” He asked, gently nuzzling the top of her head - and she nodded, feeling her heart calm down a little from it’s rapid beating.

“Good girl. Now, with your paws - grab the hemline of my pants, and pull downwards. I’ll show you my… injector.” he told her, and she rapidly obeyed - grasping the hemline, and pulling! It took a few tugs, because his pants seemed to be… stuck, for some reason, but with a big yank she managed to pull them all the way down and reveal the doctors long, throbbing, drooling, knotted cock. It bobbed about in the air, throbbing and twitching in delight as it got closer and closer to being stuffed inside a perfect cub breeding hole.

“Good girl! Have you ever seen one of these injectors before? All boys have them, and they’re very special.” He asked, rubbing the top of her head again before pushing his hips forward - letting his cock wobble about in front of her eyes, drooling a little sticky spunk onto her legs. Amy looked at it for a moment, not at all worried or scared - but interested!

“Yeah! My brother has one of those - it’s really big actually, kinda like yours. I see it a lot when we shower together, and it’s always pressed against me during night-time, as he doesn’t sleep with clothes on.” She admits to him, causing Andy to pause for a moment as the new information processes in his head… “You sleep in the same bed with your older brother?” He asks, just to confirm - which she does, with a nod.

“I see… I’ll give you and your family some advice later then. For now, do you think you could bend over the examination bed for me darling~?” he gently asked, giving her a gentle scritch on the ear. She doesn’t seem to hesitate at all as she quickly begins turning around, looking at the bed - pressing her paws onto the surprisingly comfy material, and bending over. She didn’t mean to do it slowly, she was just trying to make sure her footing was right - but it slowed her down, almost like she was doing a gentle tease to her doctor… who was more than delighted by the sight.

“That’s a good girl! Well done Amy - now, I’m going to pull your panties down so I can get the injector to its proper position, okay? Can’t inject through clothes after all!” he chuckled, adopting a lighthearted tone to keep her at ease - which, even if hadn’t done so, she probably wouldn’t have panicked anyway. She had that adorable little expression that all cubs got when they were in a new environment, or doing something new - curious about everything, wanting to watch and learn. He could see her head tilted to the side a little, eyes watching his trembling cock as he brought it closer to her rear…

“Okay! Do you want to take them fully off?” she asked, flickering her ears gently. Doctor Stedman chuckled for a moment before shaking his head, before his paws leant forward and grasped the hemline of the girl's panties. Fuck, even the view with them on was delightful - she was clearly outgrowing this pair, as they hugged her pussy and ass much too tightly. It was showing off… everything, really, and he licked his lips in anticipation as he began to peel them off of her and slide them down her thighs, legs… and finally to her ankles.

His pupils widened and his cock dribbled out a little extra splash of precum once her tight young wolf cunt was revealed to the world… or, more accurately, to him. He had to restrain himself hard to keep a professional tone as he told her: “Well Amy, I must report you look very healthy down here! Now, I’ll be inserting the injector inside you - it may feel a little weird at first, especially if you aren’t used to it. But don’t worry, it’ll rapidly feel much better - I’m a professional, after all!” he reassured her, before…

A slight squishy sound came from behind Amy as she felt the doctor's injector press against her, before it suddenly slipped… inside! She could feel it going inside of her! Her throat made a funny noise, a sort of whimper mixed with a groan as a whole host of weird new sensations began rushing through her - suddenly amplified as she felt his fingers begin rubbing something down there - something that sent tingling pleasure through her! She opened her mouth again to let out another funny sound, before a sudden push forward from the doctor caused her to yelp in delight!

Andy wasn’t surprised that this girl wasn’t a virgin. Sure, it would have been great to add her to the list of virginities he’s claimed off of cubs - but when she dropped that little information tid-bit about her brother, he knew instantly that he would have been the one to take her virginity. Usually that happened via force or during a girl's sleep… but something told him that he’d taken Amy’s virginity without a single peep of protest. Probably without her even realizing anything had happened!

His cock was throbbing in intense pleasure as her tight cunt squeezed down on the invading love rod, whilst he held onto her cute little hips. He began slowly pushing back and forth, letting his cock feel its way around it’s latest home as he gently began to reassure Amy… not that she needed it, though.

“Well done Amy! I’ve inserted the injector, and you’ll get your special injection soon. It just has to make sure to inject in the right spot, and needs a little warming up. How are you feeling, sweetheart~?” he whispered to her, gently giving that plump rump a good squeeze!

Amy was feeling amazing. Her paws curled on the bed as she felt the doctor's injector inside of her - her legs trembling softly, her breath just a little bit heavier. Trying to figure out words to describe her feelings was… more than a little difficult, but she had to do her best! She didn’t want to disappoint her doctor! “I… I f-feel… really, r-really good! T-thank you!” she squeaked out, trembling a little harder as Andy pushed his hips forward almost to the base, his large knot unfortunately stopping him from going all the way… but giving more than enough pleasure to the both of them. Getting almost his entire cock buried inside a little cub cunt was one of the most perfect, euphoric feelings one could ever achieve - and he relished every moment of it.

“That’s great! G-good girl! I’m going to speed up the warming process now…” he warned her ahead of time as he began to speed up his thrusts, his heavy overfilled nutsack slapping gently against her upper thighs. His cock slipped in and out effortlessly despite the age and size differences, coated in her good girl juices. He bit his lip to prevent a groan of delight as he began gently grinding his knot against her pussy, fingers toying with her adorable little stiff clit! He could feel his balls growing restless and impatient - despite how much he wanted to keep this going, he didn’t have long to go before he burst.

Plus, he had other patients to attend to today!

Amy was well away in her own little dream-world of pleasure, experiencing all sorts of magnificent tingles and buzzes and trembles, internally and externally. Her ears barely registered her doctor's call - causing him to repeat it, allowing her attention to slip back to him. “H-Hm..?” she grunted, resting her muzzle comfortably on the bed.

“The injection is ready now Amy… here it comes!” he warned her, speeding up a little and causing his ballsack to slap harder against her thighs - before he pushed over the edge, desperately attempting to keep his knot OUT of her for once! No matter how desperately he wished, knotting her right now would keep them locked for much too long - and he had a schedule to keep! He was successful despite how much it hurt not to, and instead he got to watch his knot pulse and twitch as thick shots of sticky spunk raced through his shaft and erupted from his tip deep inside the adorable little girl. His size made sure that he reached all the way into her depths, her womb lasting no chance against the tide of wriggling semen that began to fill her, rapidly reaching capacity as his balls kept unloading - bloating her womb into a beautiful love balloon.

Amy was squeaking, squealing, moaning and practically wriggling in delight from the feeling - he had to hold her waist to make sure she didn’t accidentally pull herself away from him, no doubt the cute little girl enjoying a wonderful orgasm. He knew the sight, and the feeling - the way her cunt clamped down, attempting to milk excess spunk from his puppy-tanks… they were all the same, and he relished it beyond words.

“Good girl… that’s a good girl Amy! You did fantastic, good girl…” he cooed into her ears, gently stroking a paw down her back as her orgasmic energy began to wane. He kept his cock inside her for a little longer, letting some extra spurts of love erupt into her - but, unfortunately, he had to pull out at some point. A potent dribble of his cum oozed down her thighs, which he quickly scooped up as he yanked her panties back up and pulled them tight and snug into her cunt - keeping all that fertile goodness inside of her.

“That was a very successful insemin-... injection, Amy! Well done!” He rapidly covered his slip, stretching his back a little as he helped Amy back to her footpaws. The poor girl was buzzing from her orgasm, legs feeling like jelly, eyes glazed with that adorable post orgasmic look… it took a lot of restraint for Andy not to lean down and gently make out with the little cub.

After all, he wanted to preserve his professionalism.

“I’m very, very proud of you. That should solve the issue of you not being pregnant, however I’d like to have a follow up check-up with you in… lets say a month. Does that sound good to you, Amy?” he asked, coaxing a gentle nod from the cute little girl. She wasn’t yet ready to speak with actual words, which was fine. It was adorable, actually.

A thought crossed Andy’s mind, and he moved over to the phone on his desk and jabbed the reception button, his personal nurse picking up in a moment. He asked her to bring in Amy’s father, before he opened up a drawer and pulled out a little tasty knotsicle treat for Amy while he waited for her father.

She took the treat with appreciation written all over her face, and she even gave him a sweet hug - which he reciprocated, of course.

There was a knock at the door, and Doctor Stedman called out to let them in. Amy’s father padded in, shutting the door behind him, looking up quizzically: “Is everything alright, Doctor?”

Andy motioned for him to take a seat, which he did so, as he leaned over his desk - gently holding Amy’s paw with his own. “Absolutely, Amy here was a very good girl and we had our entire checkup without incident. There was, however…  a revelation, if you’d like to put it that way.”

Amy’s father’s ears twitched as he heard this, his eyes focused on the doctor. “Amy required to be impregnated in order to keep her healthy - and I successfully performed an operation to alleviate this issue.” Doctor Stedman dressed up his actions in a little more of a clinical tone, not outright saying that he’d bent over the little cub and bred her… well, he was saying that, just fancying up the words.

“However…” he continued, clearing his throat to emphasize the importance. “You’ll need to make sure that she sees no further activity in her womb for a month, until her next check-up. You wouldn’t want to disturb her treatment plan. Additionally, her treatment should be supported via anal and oral methods, as regular injections help maintain the efficacy of the treatment. I trust you’ll do what’s best for your daughter? ” He stated it with such a calm demeanour, maintaining eye contact. Amy was a little too spaced out to be following the adults conversation, as she licked and suckled on her knotsicle treat, plus some of the adult words would have washed over her anyway.

“I see. Thank you, doctor - I’ll have to inform my son. Be rest assured, we’ll both be looking out for little Amy.  Is there anything else?” her father seemed  to take everything on board easily, without any sort of complaint or question, much to Andy’s delight. He instructed Amy’s father to bring her back in a month so her progress can be monitored and adjusted as needed - before waving the two away with a sweet farewell for little Amy.

The next month couldn’t move fast enough…

_________________________________________________________________________

When Amy and her father returned home, they were greeted by her older brother - Adam. He scooped Amy up in his arms and held her tight, paws perched on his lil’ sisters ass, giving it a hearty squeeze as his warm smile filled her vision. “Amy my darling! How did your appointment go?” he asked her, giving a side glance to his father who just smiled, wandering off to grab a bite to eat.

“It went really really well Adam! I missed you so much and started getting nervous, but I thought of you and how proud you’d be… and I did it! I went through all the tests, although one… one came back with a result…” she trailed off, leaving Adam to tilt his head in curiosity - and slight worry. Was his favourite little pet alright? His sweet little sister girlfriend wife? His eyes egged her on as Amy found her words…

“I… I wasn’t pregnant, Adam! The doctor was very serious and I didn’t know what was gonna happen to me, but he had a solution! A cure for the condition! He gave me this really nice injection and I need to go see him in a month…” she trailed off once more, looking at her brother for comfort. He smiled, rubbing her ears gently and giving her a gentle kiss - even as he silently regretted his own patience. He had wanted to be the first father of a litter in her little womb…

“Oh! And the doctor said I need regular injections… uh… on.. oro…” she tried her best to remember the words, her face scrunched up as what little cute braincells she had tried their best to remember the fancy adult words…

“Orally and Anally, Amy.” Came a voice from behind the two - their father, returning from the kitchen with his snack, a sandwich. He munched it for a moment before addressing Adam specifically: “She needs regular oral and anal injections, Adam. It’s for her continued health.” he took another bite as Adam processed the information.

“Did the doctor say any specific routine or amount?” he asked, curious - but his father’s shaking head answered enough. He wandered off with the sandwich as Adam turned his attention back to Amy, gently stroking a paw through her hair, his knotted cock twitching gently in his boxers…

“So Amy, how do you feel? My little girl okay?” he whispered to her, and Amy nodded quickly with a gentle flick of her tail. “Yeah! Being with you always makes me happy, Adam…” she replied, looking up at him with those big, adorable eyes of hers… Aww!

Adam chuckled before looping an arm around her waist and leading her towards the living room. His boxers were tight around his erection, twitching and throbbing against the stretchy fabric - a massive tent sticking out from his crotch, a sure sign of worry for any other girl… but not his little sister. He gently sat her down on the couch, jabbing a thumb at the TV.

“Wanna watch a movie Amy? You deserve a nice relaxing time after the appointment~” he practically purred to her, scritching her ears once more. Amy giggled and looked up at him appreciatively, and nodded! “Yeah, I’d love to! You can choose, you always have better taste than me!” she confidently stated, much to Adam’s delight. Their movie collection was… extensive, to say the least. Entire floor to ceiling shelves of movies, of all genres and types. Dad was a collector, after all.

He cast his eyes over the movies… 

He wanted something to set the mood, but not be too on the nose. There were plenty of porno-flicks, and movies that should be considered porno flicks but pretend they’re not. His eyes slid over to the TV box sets of all sorts of different shows… almost like he already knew what he wanted to put on. Spying it tucked between the other box sets, he gently pulled it out - “Tails from Tales”. A decently nondescript title, but this show was one of the longest running, most popular shows on TV - and it was still airing now!

Adam scurried over to the TV and started setting it up, his tail flicking slightly in delight. He’d spent many, many hours watching this show… and looking up clips online. Though, not the official clips of course - but rather, user clips. ‘Tails from Tales’ was a pretty generic cub-teen drama show with a cute, quirky all-female main cast. His personal favourite character was Tamlyn, a nerdy girl who wore glasses and some of the shortest skirts possible. Not just a mini-skirt, not just a micro-skirt, but practically atomic-short skirts - so pathetic in it’s construction that she might as well just walk around in her panties.

‘Tails from Tales’, despite not being rated as a porno and instead being geared towards cub audiences, was one of the most sexualized and heavily sex-focused shows available… and that was saying something, considering almost every show on the market could fit that description too!

Adam loved the show - but Amy absolutely adored it, especially since Adam had been showing it too her since she was much younger, getting her hooked on the characters and watching every episode with her. Loving brother and sister bonding time, of course - with no ulterior motive.

As the dvd booted up and he hit play, the familiar intro jingle filled their ears and Amy clasped her paws together happily! “Oh Adam, thank you! I thought you were gonna put on one of your action movies, thank you so much!” she squealed, looping her arms around him as he came closer to the couch. Adam smirked, giving her a gentle rub before she let go, but he didn’t sit down just yet.

“I’m gonna have to take these off…” he jabbed a finger at his boxers, right at his trembling, twitching tent “...because I'm absolutely boiling right now. I’m amazed you’re still standing!” he told Amy, fingers grasping his waistband and sliding them down… with a little difficulty as he had to manoeuvre his cock out of the way. It sprung free with a sudden burst, a splatter of pre-cum flying free from his tip and landing on Amy’s thighs - but she didn’t notice. She was focused on the show, after all.

“Here, let me get this off too…” he told her, crouching down to grasp her cute little skirt - and sliding it off of her legs. Amy didn’t fight back at all, attention fully on the show as one of the main characters got into a confrontation with a bully… who’s paws slipped into her crotch, fingering her as he pushed her against a locker. Licking his lips, Adam pulled her skirt free and chucked it on top of his boxers.

Adam took a seat next to her, legs parted, knotted red wolf-cock bobbing and throbbing in the open air - with thick, heavy musk wafting off of his shaft. He could see the clouds of it wander over to her muzzle, and he smiled as her nose twitched from the pleasant smell. His paw wandered over to her, landing on her thigh - squeezing gently. His fingers ran over the pre-cum splatter and scooped it up, gently pressing it onto her panties as he leaned closer to her.

“Amy…” he whispered, fingers delicately running up and down her pantie-clad crotch. Oh how desperately he wished to pull them down and stuff his knotted cock deep in there, to fill her womb with his fertile swimmers and give her a litter… but he was too late, and knowing her, she’d actually fight back - all because of ‘doctors orders’.

“Hm?” she replied, still mostly paying attention to the show - as the aforementioned character was now in the middle of an intense gangbang by multiple classmates. Adam’s paw ran across her cheek and delicately toyed with her fur.

“I need to give you a supplementary… injection. To help with your main one. I need to put my co-... injector… into your maw. Just lean over and suckle like a good girl, like you’re having an… ice cream.” He did his best to explain it in simple terms, his cock throbbing and aching in need whilst precum coated his shaft and dribbled down onto his knot. Adam’s paw gently looped around Amy’s shoulders and pulled her closer…

She naturally went without any resistance, allowing herself to be pulled and tugged. Her eyes finally slipped off of the show and onto her brother's large cock - not seeing anything naughty or inappropriate, but rather something helpful! Her brain was doing its best to work out what exactly to do, which ultimately culminated in her maw opening up as she dipped down - and slid his cock right into her throat.

Almost immediately, she gagged - she’d pushed it much too far. She pulled back a bit and her tongue slid over his sensitive cocktip, grinding into it hard - the ensuing groan of delight from her brother causing her to do it more, harder, faster - oh! The reaction from him was adorable, the way he suddenly jerked and huffed! That must be good - so she kept going, her paws holding onto his shaft for support, squeezing a little and rubbing up and down due to the slick nature.

Adam was having the time of his life. Despite his little sister's obvious amateur cocksucking ability, she was still driving him wild - whether it was the subliminal messaging of all the shows she’d watched, or just pure luck… or maybe even some natural understanding of what to do, she was doing a good job. A very good job. He reached out to grasp her head gently and move it up and down gently, though not pushing her down. She’d already gagged once, he didn’t want to push it again.

His eyes flickered upwards to the TV screen, where the other main characters had come to the aid of their friend, but had ended up caught in the gangbang too. Now it was an even larger gangbang, cum flying everywhere, their bodies covered in tallymarks and body writing… and his sister slurping on his cock, her tongue grinding into his sensitive tip, his balls churning and frothing and twitching-

Fuck…

They’d only been going for a few minutes but already he felt his defences weakening. Everything about this was perfect - moment by moment, everything just felt… right. Pleasurable too, of course, but he was slipping into pure euphoria, every muscle relaxing…

And his cum tanks were unable to keep up a strong resistance. Or really, any resistance at all.

The dam broke and copious amounts of thick, fertile brother baby-batter began spurting out of his cock  and straight down Amy’s throat. Her eyes went a little wide at the sudden feeling of injection-liquid sliding down her throat, but she rapidly began swallowing as much as she possibly could. She didn’t want to waste any of it, knowing how important it was! Unfortunately the sheer volume was too much for her young, inexperienced maw - and cum began dribbling out of her mouth, covering her brother's cock… or ‘injector’, in his own love.

Finally the torrent began to slow, allowing her a moment to breathe and recollect herself - before dragging her tongue up his pulsating shaft and gathering up all the spilled cum, swallowing that too! She’s a very good girl, she’d never dream of wasting important medicine like this! Not a single drop should be wasted, so she made sure to get every last one - her tongue looping around his cock, dragging over every little bit of exposed cock-flesh.

Adam was in ecstasy, his orgasmic pleasure being dragged out by his sister's devotion to getting every little drop. His cock trembled and twitched as she just kept going, his head overloaded with immense pleasure and euphoria.

It took a few minutes before he was able to regain proper control of himself, his paws running over her head and shoulders to gently caress his lil’ sister for such a good job well done! After that quick ‘injection’ the pair watched the show together - Amy licking her lips for spare drops of injection fluid. It tasted quite nice!

By the time the show ended, Adam was riled up once more, cock trembling in excessive need. His balls were refilled, aching to unload their love into his sweet sister once more. And so they did - Amy bent back over, wrapping her maw around his leaking shaft, and got to work slurping down her brother's kind, thoughtful injection fluid. He was such a wonderful  brother, always looking out for her and looking after her… he didn’t have to give her these booster injections, but he did!

He gave her another one later in the day too, just after lunch. And another when they started watching more episodes of ‘Tails from Tales’. And yet another when they took a shower together in the evening. Amy got on her knees each time, stuffing as much of his… ‘injector’ into her maw as she could fit, and let him unload over and over into her belly. Adam wasn’t going to complain, after all - free blowjobs were free blowjobs, especially from his adorable and overwhelmingly arousing sister. He just wished he’d been the first to get her pregnant…

That night as the two snuggled up in bed together, his cock pressed between her plump ass cheeks - he thought about doing her up the rear. But… unfortunately, he couldn’t bring himself to do it. Adam, despite lusting after his sister, had never been into anal. No doubt someone else would likely love to stretch out her rear hole…

But it wouldn’t be him.

The fact that his cock was twitching and leaking such copious amounts of love onto her fur, however, wasn’t lost on Amy. And although other girls would clearly take that as the obvious sexual desire that it was… she looked up at Adam and with a gentle smile, asked him: “Do you want to give me another injection? Your injector-thing is all leaky and hard again…”

Adam smiled at her, inviting her to shuffle down between his legs and have another injection - perhaps even sleep with her head down there in case she wanted an injection during the night. His eyes closed as pure pleasure rippled through him from yet another little-sister blowie…

Their life together revolved around her constant ‘injections’ for the next month. When they woke up - injection! When they had meal-times - injection! When they showered - injection! So on, so forth, day after day, gallons of warm loving brother spunk descending down her throat and, no doubt, causing quite the cum-addiction. His injection-juice was quite tasty after all - a fact that wasn’t hidden from Adam. Not with how often Amy said so!

Doctor Stedman also got the full brunt of Amy’s delightful chatting about her brother's injection fluid. And about the amount of injections he gave her. That one was his fault for prompting the answer, however. He’d asked her if her brother had been helpful to her and kept up her treatment plan, making sure not to skip out on her older brother's duties of care.

“Oh yes!” she’d started, giggling happily as she sat in his office once more, looking up at his face - she wore practically the same outfit as last time, just with a different t-shirt. She hadn’t been nearly as nervous as she had been the first time around, waiting in the waiting room with her father. Doctor Stedman, or Andy as she kept telling herself, was really nice! The nurses had been right, her father too - though everyone else was always right in her world…

“He gives me lots and lots of them!” she continued, tilting her head as the cogs in her mind kept whirring, doing their best to remember everything… “He usually gives me two right when we wake up, one after the other. Then after breakfast I have another one before I go to school. When I get back from school he immediately gives me another two, then usually one when we spend time together - then another once we have dinner. He always gives me one in the shower too, as well as when we’re in bed for the night. Sometimes he’ll even give me one in his sleep!” she happily related to the doctor, barely pausing for breath. He certainly couldn’t get a word in, at least.

Doctor Stedman was privately quite impressed with her older brother’s… sexual proclivity. Trying to count them up in his head as she related his performance - at least 9 or 10 daily. Per day. Really putting the emphasis there - a minimum of 10 loads of fresh cum going down this little cub-darling’ throat. How his balls kept up the production, he didn’t know. But he smiled at Amy and produced another candy for her…

“That’s great to hear Amy! I’m really, really proud of your brother. You’re extremely lucky to have him, if I do say so myself. I hope you haven’t ever refused one of his injections… right?” he asked, looking her in the eyes. It didn’t mean anything, but he was privately curious to see just how dedicated Amy was… to her health.

She pretty much instantly shook her head. “Nuh uh! I didn’t refuse a single one! Injections are really important for me, right?” God the way she said the word ‘injection’ without a single hint of its true connotation kept his cock swollen and leaky in his pants…

“That’s right Amy! Good girl! Perhaps you’d like to be a nurse or a doctor someday?” he happily mulled to her, getting to his footpaws and rummaging around in his drawers for - ah, there. He pulled out a little scanner, switching it on and brandishing it in front of him.

“Now, let’s see the good news! This lil’ thing here will show me if you’re pregnant or not - obviously, we’re hoping that you are. Wanna come closer and lift your shirt for me, Amy?” he asked, gently beckoning her.

Like the good little girl she was, Amy immediately got to her feet and moved closer, paws hooking the bottom of her shirt and yanking it upwards. She didn’t take it fully off, just held it up - as Doctor Stedman started to run the scanner over her belly. After a month of gestation, she likely would have been showing a small bump by now.

But she wasn’t.

Amy saw Doctor Stedmans expression change ever so slightly - funny that. She was overwhelmingly naive and oblivious in the face of any and all sexual topics… yet, here she was, accurately noticing the change in her doctor's muzzle.

“Is… everything okay?” she asked him, a small note of fear creeping into her voice. Andy didn’t reply, simply running the scanner back over her belly before withdrawing it, clearing his throat - and looking her in the eyes. After a moment of staring at her tits, at least.

“Well… I’m afraid you’re still not pregnant, Amy. Now before you-” he managed to get out, before Amy gasped and lost her grip on her shirt, as it fell back down to cover her front. She wobbled gently on her footpaws and Andy reached out to steady her, continuing before she could get any words out: “BEFORE you start to panic, Amy, this isn’t too bad! It just means the first injection didn’t take. Some medicines require multiple doses before their effects… come into effect. We also have some tools available to… help things along.  Understand?” He comforted her, gently running a finger over her cheek. She nodded, but still looked worried and anxious.

Andy made sure to keep his gaze and tone neutral - but inside, he was pissed. How had she not fallen pregnant from his cum? There’s no way he was starting to get too old for this - hell, male sperm could still impregnate a fertile girl way into old age. Perhaps Amy’s womb wasn’t yet ready at the time? It could happen, a delayed fertility growth… but thankfully something easily fixable.

His paws ducked into the drawers once more - this time, the medicine drawer. Or, perhaps, ‘medicine’ drawer. He produced some brightly coloured pill bottles, some of which weren’t marked - but others with words such as “FurTile” and “Ferrrtill” on them. He popped the pill bottles open and began slowly amassing a pile of pills from each bottle - one pill from each. After that, he put the bottles away and scooped up the large pill-pile. He’d taken a lot of different pills this time around, much more than usual.

He put them all into a bowl and began to mash them up into a dusty powder, all these funny colours mixing together - before he poured the dust into a cup, and filled said cup with water and gave it a stir. The water took on an almost milk-like colour, with so much pill-dust inside that it was hard to identify as water anymore. This was a far cry from an invisibly spiked drink…

“Here, drink up Amy!” he told her, presenting her with the water. She did as instructed pretty much instantly - with only the tiniest amount of hesitation as she looked at the water, probably the only hesitation she’d ever shown in his office. He couldn’t fault her for that one, the water did look pretty… not-water like. He usually didn’t spike the fertility drinks this hard, after all. But he was kinda pissed. Really, only a single pill from any of the named brand companies would have been more than effective - hell, most of the named brands ended up guaranteeing entire litters despite the branding claiming “Will cause at least one pregnancy!”

Naturally, whenever a girl had an entire litter of 4+ puppies growing in her, the company would just point out the “at least one” part. Which was smart, of course.

But then there were the unnamed pill-bottles. The back-alley, black-market, experimental out of the lab types of pills. The ones that got pawned off from breeding facilities. The ones from underground genetic enhancement bunkers. The ones that he couldn’t even guess at the potency of their effects for.

And he’d crushed up about 15 or 16 or so of these different types of pills, mixing them all up into one ultimate drink that Amy was gulping down. He could see her wince a little as she dutifully and obediently swallowed it all down - the amount of pill dust had turned the liquid a little more goo-like, but still drinkable. She swallowed it all however, without any word of protest, or even a pause… just the wonderful sound of her throat: Gulp, gulp, gulp.

“Good girl Amy! Well done! Here, take these~” he happily handed over a big handful of his candies, seeing her entire face light up in happiness. It was adorable, and his cock ached harder at remaining trapped - but thankfully, that would soon change. She was practically bouncing on her chair in excitement over the candy, whatever weird taste of the medicine drink immediately forgotten… and her movements gave Andy an idea.

He began sliding down his pants, letting that long, pulsating knotted cock free of its cruel prison. It bobbed and throbbed in the open air, thick wafts of hefty musk filling the space around his crotch. Amy didn’t really seem to pay much attention, she was already enjoying one of the candies - Doctor Stedman had to clear his throat for her attention.
“Alright Amy, you’ll be having another injection today - how about hopping up onto my lap so I can slide the injector into you?” he told her, beckoning her with a paw. Naturally, without any hesitation, Amy hopped off her chair and onto his lap instead - straddling him happily as her face grew close to his. Her panties were still in the way though, gently rubbing against his leaking, warm shaft. Of course, a silly girl like her forgot such a detail…

But it didn’t matter. His paws gently grasped her hips and slid under her skirt, grasping the tight, comfy fabric and pulling them down her thighs. He had to move her about a little to get them past her knees and off her ankles, before he flung her panties onto his desk. She didn’t complain, but he saw with delight the way her face moved into an adorable depiction of pleasure as he began sliding his cock deep inside her young snatch once more.

“Amy? You know that bouncing you were doing on that chair? How about you do that on me too. It was really cute, and I’m sure it would help the injection process if you act like you usually do!” he told her, giving her squishy rump a hearty squeeze. Amy squeaked an “Okay!” before immediately beginning to bounce up and down - quite hard and fast too, bringing out a surprised grunt from Andy. She didn’t stop at his funny noise though, and his back arched in delight as the adorable little cub cutie began bouncing up and down on his invading adult cock.

His paws reached up to hold on to her hips as Amy bounced and bounced, happily getting into the groove - for her, this felt amazing! It was so much fun! It reminded her of those fun ‘Ride A Wolf’ rides at amusement parks - the one where you sit on a werewolf and it buzzes and vibrates, jostling her up and down. She loved those rides, they always made her feel amazing… like doing this was! Wow, going to the doctor was just so much fun~!

Andy couldn’t help but groan in delight as his cock was treated to such an energetic riding from such an adorable lil’ dummy-cub! She just wouldn’t stop bouncing, with sweet little squeaks erupting from her maw here and there - and the knowledge that her womb was no doubt catching fire from the sheer amount of fertility pumped in there. Hell, even his dribbling precum had probably gotten her pregnant now - there was utterly no way her eggs would survive a single sperm-cell without getting inseminated now…

And they didn’t have to wait long, either. Amy was so energetic and powerful with her bouncing that his cock began pulsating much faster than he anticipated, his balls churning with love as his cum began erupting out of his cocktip and into that sabotaged womb, copious oceans of virile sperm slamming into her eggs and this time… this time there was no doubt of the impregnated outcome. Her womb was a forge of fertility as wriggling wolf-spunk descended into her eggs and ensuing she would carry on her lineage…

“Fffucckkk…” Andy moaned gently and involuntarily. His entire body was limp from pleasured exhaustion as his balls unloaded, every nerve in his body filled with that orgasmic relief. Everything was right in the world, everything felt fantastic… everything-

“Doctor Stedman!!” Amy’s shocked voice broke through the haze, as he looked up at her surprised face. He squinted, unsure what the problem was, and as a few seconds of unbroken silence fell between them, Amy actually managed to continue: “You said a BAD word!”

Oh.

It took every ounce of his willpower not to laugh. No doubt the amusement was in his eyes however, as Amy’s head tilted in confusion as she looked at him. He raised up a paw and gently stroked her hair.

“Oh Amy, I would never  do such a thing. I just let out a little yawn, like this!” He demonstrated, opening his maw and vocalizing a “Fffwuuaaarr…” sound. It seemed to please Amy, who instantly apologised for her assumption. Andy just chuckled and petted her head softly, lovingly grinding her back and forth on his cock. The two sat there together for a few minutes as Andy bathed in the orgasmic afterglow, imagining his sperm getting to work inside of her…

“Alright Amy, I think we’re done for the day. I’ll see you in another month, okay?” he told her, looking her in the eye. Amy nodded with a smile and answered “Okay!” before starting to clamber off of his lap. Immense amounts of cum began leaking from her well-used cunt, dribbling down her thighs… but she didn’t seem to care. She just gathered up her candy and began walking towards the door, before Andy called out: “Wait a moment!”

He got up, approached a curious Amy - and slapped her plump wobbling ass. “There was a fly on you, I got  it though!” he happily proclaimed. Amy smiled and thanked him, before waddling off towards the waiting room to meet her father.

She’d forgotten her panties. Oh well, Doctor Stedman had wanted a pair for his collection anyway.

_________________________________________________________________________

Naturally, Adam kept up his brotherly duty of giving her reliable booster injections. There’s no way he’d stop milking that free orgasm cow - or, perhaps it was the other way around… making her milk the free orgasm sausage. It didn’t matter, he was such a caring older brother. Always looking out for Amy, for her safety and well-being.

The problem was, it was getting a lot harder to keep his cock out of her pussy. Thanks to his little sister's impressive downing of such a potent mixture of fertility and aphrodisiac pills - her entire body had been shoved into such a prime state for breeding that it bled out to affect males around her. Specifically, her scent was driving him utterly rabid with lust, his nostrils constantly drinking that intense, potent smell that wafted from her soaked, leaking sex. Seriously - she walked around the house bottomless, leaving a tasty trail of girlcum behind her wherever she went.

He’d stepped up the oral injections to compensate, but it was getting risky now. His mind kept wandering into territory that came close to breaking whatever veil kept her from understanding the real nature of… everything around her. So often he thought about bending her over or pinning her down and just pounding her womb senseless… but he held out.

The same couldn’t exactly be said for her male classmates.

Amy was naturally the target of a lot of sexual bullying due to her innocent nature. Of course, the moment one of the class perverts (so, every male in her class…) had grabbed her ass for a quick fondle n’ grope, and she’d shown no reaction - it had spread like wildfire through the school that she was an easy score. Paws frequently found themselves accidentally brushing against her tits, ass, thighs and cunt daily - boys kept dropping their pencils under the table, and they rolled under her chair so their muzzles were stuffed right up her skirt when they went to retrieve it. Fingers kept slipping between her legs whenever a boy sat next to her.

So of course, their nostrils picked up the wafting scent of a breedable pussy the moment she first walked into class after her doctor's appointment. Cocks began swelling and throbbing, leaking potent fertile cub-cum into their pants. Eyes darted over to her, immediately tracing the source of that intoxicating scent. Even the teacher had to clear his throat a little, but perhaps that was just to get the class’s attention again. It didn’t work, though.

The moment Amy was in a vulnerable position, such as out in the hallway - she was pinned by numerous paws, held against the wall. This wasn’t anything new, but when they began to slide down her panties in tandem with their pants, revealing throbbing, pulsating, leaking cocks to her - or, in her mind, “injectors”... she started to pay attention. As the first cocktip began growing closer to her exposed, defenceless pussy - she spoke up. For the first time ever, in fact, she held off the advances of the boys.

“H-hey, wait! Please don’t put your injector in there yet - I have to wait for my doctor’s approval! He said that uhm… ayn-all and orr-ral is okay though!” she informed them, much to their bemusement. Glances were exchanged between the leading boys, their cocks trembling in anticipation - and the first boy ignored her. He began to push his cock against her pussy once more, and the obvious flash of panic in Amy’s eyes was impossible to ignore.

“N-no! Not in there! Let me go!” she actually started to struggle. That was the most surprising, off-putting thing… she never did that. Never tried to struggle, to run - it caused the boy to pause, long enough for her to calm down. Her pleading gaze broke through, and with a sigh… he gently spun her around, and aimed for her ass. It would have to do.

Amy was held against the wall as the first cock slid up her rear, making slow progress at first due to the tight, virgin state of her anal cavity - but soon, after more and more boys took their turn, it began to loosen up. Loud, lewd slaps of flesh on flesh filled the school hall as more and more boys turned up to wait their turn. Cum began flowing down Amy’s thighs and legs, forming a large sticky puddle beneath her.

And after every boy finished bullying her ass, she always said thank you. It drew a surprised eyebrow almost every single time - but they all had that unspoken pact not to draw too much of her suspicion. They just smiled and carried on with a quick “You’re welcome!”

Amy herself was having a wonderful time. Injections like this felt wonderful! Sure, she absolutely loved her brother's injections (especially because they tasted so good…) but these made her feel all sorts of incredible feelings! At first it was a bit uncomfortable, even painful… but it rapidly changed, switching to intense pleasure that made her legs wobble with weakness. Even now she was struggling to keep herself on her paws - thankfully, the boys holding on certainly helped with that.

She didn’t know how long she was there for, held against the wall, injector after injector slipping into her rear and pounding her senseless - pounding orgasm after orgasm through her, though she didn’t know that. She rode every orgasmic wave with complete naive innocence, enjoying it yet not fully understanding it. She just attributed it to her injections…

Which was… technically true.

After that day, anal injections became a staple of her school life. Held against the hallways between classes, bent over the cafeteria table at lunch, mounted like the dog she was at break-times… a true slut to the core, yet never capable of understanding it! Enslaved to her constant orgasms, chasing goals given to her by another, for his own benefit…

But she was happy. As long as the boys kept their injectors away from her pussy, she was happy. Who wouldn’t be, having orgasm after orgasm forced into them? Being turned into public school cum dump property? Even the faculty began getting in on the action as the next month slid by! It wasn’t uncommon for Amy to have an after-class meeting to discuss the course of her medical treatment, and for a quick injection boost to help her along.

Before the month was up, the fruits of Doctor Stedman’s treatment were beginning to be evident. With a week to go before her checkup, Amy’s belly had grown ever so slightly - not much, but enough. She didn’t notice of course, not really. Maybe she glanced at it in the mirror and thought she’d had too much to eat. Some of her classmates noticed though, their paws gently rubbing and stroking her belly during their injections… or just idly, when in class.

Doctor Stedman was ecstatic when he got to see her again.

He already had his little scanner ready when she came through his office door, but his eyes gave him all the verbal clarification he needed. Of course, he was going to scan her anyway - maybe she’s just eaten too much pizza lately… 

Amy recounted her new-found school experiences as Andy passed the scanner back and forth over her belly, staring in delight at what he saw - his own puppies growing in her womb. He wasn’t able to get an accurate count on the litter size though, but that was alright. He knew it was going to be large. Very, very large.

“Amy, I am extremely pleased to let you know that you’re officially pregnant! Well done!” he exclaimed with a big hug for the adorable wolf cub. Amy squealed in happiness at her successful impregnation, jiggling on her heels as she was filled with delight - though of course, without any knowledge of the consequences or future. Andy’s happiness and excitement of a job well done was more than enough to keep her in good spirits!

“So I’m all healthy now?!” she asked rapidly, and Andy gave her the coveted double thumbs up! She squeaked in delight, not even raising a word in protest as Andy’s paws grasped her hips and lifted her up and onto the examination table once more, spreading her legs and pulling down her cute little tight panties. Nor did she appear at all frightened as he released his fat, throbbing cock again… letting it slap over her belly before rapidly rubbing back and forth, moving down towards her entrance…

“Here, as a parting gift from me for your excellent attitude towards your… health~” Doctor Stedman whispered to her, leaning forward and kissing the top of her forehead. He pushed his way inside as his lips moved down to lock with hers. He straddled her and pinned her down on the bed in a slow, loving mating press as his cock sunk in deep, before his balls rested against her waist.

He was slow, loving and gentle this time. Romantic. Up and down, a rhythmic loving pace. He wasn’t going to last long anyway, as Amy was most certainly his favourite cubby fucktoy… but he wanted to savour her. Enjoy her on a deeper level. It was cute, really. And of course, it was romantic too. But she didn’t understand it that way, and that was okay.

Because he was having so much fun with her.

In, out, in, out. His cock pulsating and twitching, throbbing and rippling. His litter was growing inside of her - healthy and secure, this little cub would host his own cubs. Of course, his fatherhood tree stretched out amongst a whole host of young girls (and a few women, too!) as most, if not all of the female cubs who came into his office eventually left with a wombful of pups.

But Amy was special.

Even as he drained his balls deep inside her once more, giving her a final big injection of warm sticky love - he was already planning ahead. His muzzle dipped to her ears as his cock throbbing whilst cum shot from his tip - and he whispered to her… “Make sure to come see me again the moment you’re up on your footpaws after birth. We’ll need to keep you in a constant pregnant state, okay? It’s for your health…”

Of course she believed him. Why wouldn’t she? He was a professional - a medical expert. He knew what he was talking about and she should always respect and listen to experts, the ones smarter than her. Of course, every boy was smarter than her - and thus they were experts too. The cycle wouldn’t end…

As Andy gave Amy a pat on the head, returning her panties to her this time… he told her something important. He owed it to her brother, after stealing the first knock-up rights from him.

“Amy, as you’re pregnant, your pussy will need regular injections. The ban is now lifted - let everyone know, especially your brother, that they can now inject directly into your pussy.”

His satisfied grin only grew wider as he heard the happy “Okay!”...

_________________________________________________________________________

Loud slapping sounds echoed around the living room. The sound had been present since they woke up this morning, now it was late afternoon. A constant, lustful slap slap slap. Interspersed with groaning and moaning, heavy breathing - and squirting. Thick, heavy sounds of squirting.

“I’m gonna get some water, you want a snack?” came the voice of Amy’s father. He sounded a little tired, like he’d been running or exercising all day long. A reply didn’t come immediately - not until a wet schlick and pop, and a few pants.

“I’m good - I’ve got more than enough to snack on here!” Adam’s voice replied, earning a nod from his father as he wandered off. Adam immediately went back to suckling on Amy’s fat, swollen, milky tits. He grasped her left breast and squeezed, causing a squirt of milk to erupt and trickle down onto her swollen belly. It was massive, stretching her out larger than multiple beach balls all crammed together. She was heavy too - but that just made lap-sitting all the more pleasurable, with Adam’s cock shoved deep inside his little sister like it had been the moment she came back from the doctors three months ago.

She was due in about a week perhaps, and Adam was determined to get the most nourishment out of her that he could manage. Her milk was intoxicating, and he was practically stealing it from the restless pups that kicked and wobbled in her womb. Hell, her body had steadily been producing more and more of the lush, tasty liquid - no doubt tricked by all his milking that the pups were here, and hungry.

Not that he complained - he was insatiable. Even when dad was taking his turn to blow his special little daughter, Adam never skipped out on giving his sister a proper milking. Speaking of dad…

“I’ll take another round but… I’m beat after that. Your stamina is… impressive, son.”

He’d returned with a big pitcher of water, downing some of it in a single long gulp. Adam smirked as his balls began to unload another fertile batch of brother-baby-batter into his lil’ sister. That was her way of milking him back - milking the cum out of his balls. That’s what he’d told her, at least.

“Yeah? Thanks dad, I appreciate it. I’m gonna need it for when I knock her up. I’m gonna go the whole day and night to make sure her next litter is mine. You uh.. might have to wait.” he admitted, wincing slightly. His dad chuckled, gently placing a paw on his shoulder.

“That’s my boy. I’m getting you two some more siblings afterwards, though.”

They shook on it.

Of course, whether Adam would beat Andy in the race to impregnate Amy next wasn’t known. Neither party knew of the other's intentions. It was a race against time and sperm. Who knows who’ll be the victor?

Though in the end, Amy always won too.
