Cosmo trots from the kitchen into the living room, then hops up onto the couch. His partner, Quinn, and his housemate, Astera, are both out for the day, so he's spent the morning doing all the chores around the house that he can think of—scrubbing floors, vacuuming, washing and hanging laundry, emptying old leftovers from the fridge, making the bed—all of which are difficult to do when you're a quadruped like Cosmo! And now, with all those chores finished, he's planning to spend the rest of the afternoon relaxing. He flips on the television with a fore-paw, then sinks back into the pillows and gets comfortable.

Cosmo's what someone might call a 'space shiba', an alien creature who looks outwardly much like your everyday, run-of-the-mill Earth shiba inu, just with unique colors. His coat is made of various shades of chocolate brown, with a dark tail, medium along his back and paws, and lighter countershading along his underside and legs. His pawpads and the insides of his ears are a bright azure blue, and along his back are tiny polka-dots of blue, violet, pink, and orange. 

Of course, he's not just a shiba with a unique coat of paint, though. He talks, and he does chores, and he goes on shopping trips and adventures, and—though they're not nearly as dextrous as true hands and he needs tool assistance with finer movements like holding a pen—his paws are way more capable at grabbing and manipulating than a Terran dog's paws.

Only about ten minutes into his relaxing tv time, Cosmo realizes two things:

One: he is not paying any attention to this show.

Two: he is bored.

He flops over onto his side. "I wonder how Astera and Quinn are doing," he sighs against the cushion. He cracks one eye open to glance at the clock. At this point, the two of them are likely wandering the market, browsing the stalls of all kinds—bizarre and delicious alien foods, machine and ship parts, trinkets, home-made handicrafts.

Quinn is a big, soft Zangoose. While most zangooses have red markings in the fur on their chest, head, and forepaws, Quinn's are saffron orange. His heart is just as big and soft as he is, a gentle and loving person, almost motherly with his affections.

Astera's a space shiba just like Cosmo, but differently colored. Her tail is white, and the countershading on her belly and legs is white-chocolate. She's in the middle of shedding right now—her longer, thicker winter coat of seafoam green fur giving way to the shorter, softer rosy brown fur of her summer coat in a cute salt-and-pepper look. She likes to tease, but she can sometimes take it too far into playfully mean.

Cosmo wriggles on his back, then rolls over and burrows his snout into the plush cushion. All three of their scents intermingle in it, a comfortable and soothing melange that feels almost like a hug to have it all in his fur. Almost. He could go for the real thing. Or something to keep his mind occupied. 

"Maybe I should have gone with them." He wonders what they might have gotten up to with him there joining in on the adventure. They usually try to walk around with Quinn in the middle so he can use his height advantage to keep an eye out, but he tends to get distracted by cheese.

In Cosmo's mind, Quinn stops to discuss the finer points of cheese and wine pairings with the owner of a produce stand, and Cosmo and Astera trot along to find something more interesting to do while they wait. Then Astera darts between two stalls and into the access way behind them, and Cosmo's imagination follows her, around the corner and nearly nose-first into her aquamarine spade. She's right around the corner, presenting herself with her front down and back legs stiff, curly tail wagging. Her pussy is even more puffy than usual, drenched, with the scent of her need coming from it in lustful waves

She's in heat.

On the couch, Cosmo springs up. That day dream turned suddenly sexual! He shakes out his head as if to clear it of those thoughts. He hums.

"I could have sworn I actually smelled a bit of her heat then."

He lifts his snout to give the air a couple of quick sniffs. Nothing. Still, he closes his eyes and tries again, sniff sniff, following his nose back down to where he was lying a moment ago. It's barely there, just the tiniest hint, but sure enough—right where he had his snout in the cushion when his daydream got sexy, he finds the lingering scent of Astera's arousal and pheromones. She must have just started her heat, and now there's a trace of it left behind on the cushion for him to enjoy.

So enjoy he does.

He's alone here, after all, so he may as well take care of himself.

He runs a forepaw down his front, tweaking every pink nipple on his left side along the way, mentally doing the same to Astera's aquamarine nipples . At the lowest, he pauses to give that one extra attention—roughly rubbing a tight circle around it with the pad of one toe, flicking it with a claw, grinning while he imagines her delighted groans.

He looks down. His cock tip has only just begun peeking from his sheath. He decides that won't do—he can't jerk off if he's not even fully erect yet! He stretches his muzzle down, intent to lick himself, but stops before he reaches his sheath. Grinning to himself, he gently taps his nose to his cocktip.

"Boop." He chuckles, then marvels at the feel of his warm breath against it. It twitches, just as eager as the rest of him to keep going, and a bead of precum forms on the tip.

He flicks out his broad tongue to lap once, twice at his exposed tip, then dips it into his sheath to get at more of his length. Carefully, he strokes himself with his tongue, in and out, and circling around his sheath. As more and more of his cock emerges, he opens his mouth to allow his length inside. As it grows, he keeps up his licking, with more and more shaft to lick, until he coaxes it to full size—nearly a third the length of his torso. He pulls away, slowly, with a long slurp as it exits his muzzle, then licks his chops.

"Alright, now I'm ready to go!" His cock, now standing tall and proud, gleaming with his saliva, gives an enthusiastic twitch. He rolls onto his back, head resting on the spot Astera left behind, and takes his shaft in one forepaw. 

"Where was I?" He gives a little shuffle to the side so he can turn and nose in at Astera's scent. "Right, heat."

As he lets her scent carry him back into his fantasy, he gives a slow stroke of his cock, tip to base.

He snuffles deeper against the cushion as in his imagination he nuzzles his snout into her plump, aquamarine spade. 

The potpourri of the market—various scents of fruits and veggies and sweat and dirt and machine oil and exhaust—all fade away, drowned out by one overpowering scent. Astera's heat.

"You gonna fuck it, or just worship it all afternoon?"

He pulls away with a chuckle. She's looking expectantly over her shoulder, obviously excited but trying to play it off as impatience. He pets her rump with a paw.

She's so wet, it's running from her clit into a puddle of her juices between her legs. Eager for one last taste before he mounts her, Cosmo dips his muzzle in and—

He gets a tongueful of couch cushion.

"Well that's a lot less awesome than eating Astera out!" He chuckles, then smacks his lips. "Oh, bleh. I got fuzz on my tongue." He scrubs it off with his paw, then shakes his head. "Okay, back to jerking it." He takes his cock in one paw, hefts his balls in the other, and slips back into his daydream.

In his imagination, he hops up onto Astera's hips, then scooches forward bit by bit until his tip nestles in against her spade.

"Finally! I was worried you were never gonna mount me!"

"Don't worry, I wasn't gonna leave you hanging." He shuffles a bit to get into position, forepaws around her middle and head resting on her shoulder.

"Then let's hurry up, before someone finds us."

He humps right in, hips smacking into hers and balls slapping against her clit.

"Yeeesssssss." She gives a full-body shiver of delight at being filled. "Don't forget to tie!"

"Hehehe, okay, okay." He sets right into rapid humping. He takes a deep breath in her ruff. "You smell so good when you're in heat."

On the couch, both Cosmo's forepaws stroke rapidly up and down his long shaft. Every little bit, he turns to sniff at the spot of Astera's arousal in the cushion. Then Cosmo—real Cosmo who is having this daydream—has an idea.

He rolls over on the couch so he's face-down with his snout against the spot of Astera's heat-scent, then rises onto his back legs, perking his rump up and keeping his head and forequarters on the cushion. With his forepaws down the length of his body, he's able to keep a hold on his cock. He gives a couple testing humps into his paws and smiles. It's a pretty workable approximation of a mount, if he says so himself.

"That's much better!" He takes another deep sniff at the spot to get himself back into his little fantasy.

Using his paws as a crude simulacrum, he holds them steady while humping into them in time with his imagined tryst.

"You know I cleaned all the floors in the house? And I got the dishes washed!"

He pauses, switching instead to slow strokes and gentle squeezes, as in his mind Astera takes over for a moment.

"Oh yeah?" She pushes back into him, slowly, clenching down. "And what about the laundry?"

"I did that too!" He emphasizes it with a full-length thrust, hips clapping against her rump. She barks and swoons. 

"Wow, sounds like you did just about everything, then!" She turns an impish smirk his way. "What, were you bored and lonely without us there?"

He chuckles. "A bit, I guess!" After a few more humps, he sighs. "I kinda wish Quinn was here, too."

"You wanna get fucked while you fuck me, huh?" She laughs as he nods rapidly against her ruff.

"Oh here you two are!" Quinn's soft voice approaches from around the corner. "I was a little worried." He lovingly tousles Cosmo's ears with a claw.

"Oh hey Sunshine! Just—" he interrupts himself with a growling, rrrrrf, as he gives Astera a couple of extra-enthusiastic humps, "—helping Astera with her heat. Wanna fuck me, while I do?"

Quinn's clothes—khaki cargo shorts, sandals, and an aloha-print shirt that are all endearingly nerdy—are off in an instant.

"Of course, Cosmo," Quinn purrs lustily. He lines up his tip with Cosmo's anus. "Anything for you, Stardust." Quinn presses in, humping Cosmo into Astera and making both of them bark their pleasure.

The trio settle into a rhythm together, Quinn humping Cosmo, Cosmo humping Astera, Quinn humping Cosmo into Astera. On the couch daydreaming, Cosmo's own rhythm speeds up and falters as he nears his orgasm, balls slapping into his paws with each thrust..

"Uh oh," he groans into Astera's ear, "my knot's engorging."

He slows his two-pawed efforts on himself.

"Well make sure it stays inside!" Astera's voice is frantic with need.

Cosmo grips firmly and slips both paws down to his base in one last, sloooow stroke. As he reaches his thickening knot, he squeezes at it rhythmically to match his imagination—Astera's plump spade squishing against the widening bulb and clenching down on it as it presses in. He gives a couple little humps to "force" it through his grip, both paws grasping around the growing bulb, tighter each time. 

As the knot nears full size, he takes one last full length thrust, out then in, jamming the knot through his tightly held forepaws.

"Mnnn, Astera," he moans aloud against the couch cushion. 

One paw he slips further down, all the way behind his knot to grip the base of his cock while the other he keeps in place on his knot. In his fantasy, Astera tumbles into her own orgasm, clamping down on him in a rapid tempo. On the couch, he matches with his paws. Her rhythmic vaginal clenching—and his paws imitating it—gets his knot bigger and bigger, his body buzzing with anticipation as she drives him closer and closer to his own climax. 

"We're tied now, Astera," he groans into her ear, "not long 'til I'm cumming in you." She shivers under him, clenching harder on him. Over his back, Quinn leans in, too, causing his cock to press tantalizingly against Cosmo's prostate. Cosmo's cock twitches threateningly inside Astera. On the couch, Cosmo's ready to blow any second. His cock throbs in his paws' grip, slapping against his belly and leaving a splattered smear of precum between his teats.

"Aaagh, Cosmo!" Astera drops her front to the ground, panting and groaning, putting a paw over her snout. "It feels so good!"

"Here it comes, Astera, just like you need." He squeezes around the base of his cock, gently tugging as she moans and begs under him.

"Do it, Cosmo!"

"Gonna knock you up, Astera." His grip flutters, squeezes in time with her pussy, rubbing around his knot as he tightens the other paw's toes down in a ring around his base to imitate the enthusiastic seal of her vulva. "Gonna fill you up with so many puppies—a whole litter."

"Yeeessssss! 

But what if...

He pants against the couch cushion, easing his ministrations to follow the thought. What if he was in heat, too? What if he needed breeding, too?

His anatomy differs from the run-of-the-mill Terran shiba inu in more ways than just superficial, after all! He's functionally hermaphroditic. His balls are actually more like specialized ovotestes, containing both testicular and ovarian tissue. He even has a womb! It actually exits his body through his rear, though, so his anus is kind of like a cloaca, being multi-purpose.

And he's imagining Quinn fucking him in the anus right now, just as ready to blow as he is.

So what if he needed to be knocked up, too?

"Quinn! Quinn, I'm in heat, too," he moans to his beloved Zangoose boyfriend over his back. "I need you to breed me, Quinn! Please, inside me too!"

Quinn answers by kissing his ear, so gentle, and shoving his cock right up against Cosmo's prostate.

Astera growls against the dirt. "Just cum already!"

Cosmo obliges.

Growling and panting, he gives himself over to climax, large cock throbbing inside her and large, full balls tensing up with the first blast of his cum rockets into her vagina.

Astera screams. If there was any doubt that others knew what was going on in the alley, it disappears with Astera's exultation at being filled. She practically vibrates under him, legs shaking and twitching, toes flexing and claws digging into the ground.

"Yes yes yesssssssssss!"

Cosmo is in heaven. Panting, tongue out and drooling into Astera's ruff, he pumps his fellow space shiba full. Jet after jet after jet he pours into her vagina, quenching her heat.

And then Quinn cums too.

Cosmo's orgasm has him clenching down hard on Quinn, surprising the zangoose into a sudden orgasm.

"Uh! Cosmo." Quinn hunches over his boyfriend as he joins both space shibas in climax. Between whimpers, he pets softly over Cosmo's back and head and sides, huffing against his ear. His balls clench up against Cosmo's as he paints his insides in zangoose cum.

All the while, their orgasms feed into one another. Astera's heat and vice-like pussy milk Cosmo, Cosmo's knot and prodigious production sate Astera. Cosmo's clenching anus draws Quinn on, Quinn's cock against Cosmo's prostate and cum flooding towards his womb pushing him to cum more. For several minutes, they all three whimper and strain against one another, tumbling from one orgasm into another, caught at the peak of pleasure.

When, finally, their combined climax wanes, Astera's shaking legs give out and she flops to the ground. Cosmo and Quinn come along with her with a surprised gasp, landing in a heap. They catch their breath and enjoy the afterglow, nuzzling one another.

Astera turns to meet his eyes over her shoulder. "Gonna take care of me for real when me and Quinn actually get back?"

"Yeah." He nods against her shoulder. "Whatever you need, Astera, I'll take care of you. If that's breeding, I'll breed you. If it's not breeding, I'll not breed you, whatever you say."

"So eager to do whatever I say, huh?" She giggles at him as he nods rapidly. "What do you say, Quinn?"

"I say I love him for his eagerness." He places a gentle kiss to Cosmo's ear. "Hear that? I love you, Cosmo."

"I love you, too, Quinn!" Cosmo's curly tail wags rapidly.

Quinn smiles down over Cosmo's back, grinding his hips in a lazy circle. "You are so good, so kind, so helpful, Cosmo."

"That's right I am. I'm a good boy."

"I'm a good boy," Cosmo says, out loud, to the empty living room. He blinks a couple times when he realizes, then chuckles at his own excitement, at how into it he got.

He pants, slowly catching his breath and coming back down from the ecstasy of orgasm. His legs quiver and twitch, then give out. He lies still for a moment, enjoying his own—real—afterglow, tail wagging contentedly. Floating along on cloud nine, he nearly falls asleep, until he recognizes the uncomfortable sensation of fluids cooling in the fur of his belly. He rolls over.

"Awww, heck," he whines. "I just made a real mess of the couch."
