Smoky grumbles, tightening the gearbox of the car she's working on back into place. It's been a long morning and afternoon tuning the vehicle to the owner's wishes, but she feels it's almost done. The tyres have been rotated and the alignment fixed, and now, with the gearbox cleaned out and re-greased, she reckons it's ready for a test run.

The possum lowers the car onto a test bed before climbing in and starting the ignition; after giving the engine a listen, she smiles proudly. "Purrin' like a kitten!"

"Ahem."

"Huh?"

Smoky looks over, spotting the owner of the car in the shop – A tall, fluffy, shirtless cheetah named Kane, wearing naught more than a beanie, fingerless gloves, and shorts, all in black – Standing with his arms crossed and an unamused look on his face.

"I'll let that slide," he says. "Are you done?"

Taken a bit aback by his brusque tone, Smoky kills the engine and nods. "Well, yeah, I'd say so. She's all tuned up like ya asked for! Even rotated yer tyres for ya, and-"

"Excuse me?"

The possum's expression lowers. "What?"

"I didn't ask for that. You'd better not charge me for a rotation."

Smoky pauses, taking a deep breath, before letting out a sigh. "No, I wasn't going to. It's just somethin' standard I do when workin' on a car. Tyre rotation, oil change if needed, and-"

"I didn't ask you for an oil change either. Are you trying to-"

But the possum cuts off the cheetah, her tone clearly annoyed. "If y'all'd let me finish… I do it as part of my standard service fee. Y'all won't be gettin' charged none extra. Jus' want yer car to be safe."

"Hmpf," scoffs Kane.

Smoky shakes her head, climbing out of the car and standing to her full height of five-foot-nine – Noticeably shorter than the six-foot-three feline. "Y'know, most customers say 'thank you' for a free oil change and tyre rotation."

But the cheetah shoots back "Look, as long as you did the tuning that I asked for, then our transaction is complete."

The possum, though, narrows her eyes. "Not 'till ya pay for the service, it isn't."

"What?"

"It's not much of a transaction if I don't get paid, now is it?"

There's a moment of silence as Kane takes in her words, before he eventually huffs and nods in defeat. "Suppose you're right. I'm sorry. Been a really rough day."

Smoky's expression softens upon hearing him apologize to her. "Aw, it's okay. These things happen. I'm not takin' none of it personally."

The cheetah lets out a sigh. "Work sucked, even more so because I had to run there since I didn't have my car. Plus a bunch of stuff going on aside from that. But I shouldn't have taken it out on you. That wasn't right."

"Well, no, it wasn't, but I forgive ya." She smirks, leaning subtly closer. "Tell ya what… How 'bout I help make yer day a bit better, eh?"

Kane's ears perk at this, his brown eyes noticeably glancing downward to the possum's chest for a moment before looking back into her lilac eyes. "R-Really?"

"Mmmhm," she responds seductively. "Such a big, handsome cheetah like you deserves a chance to relax. And bein' frank with ya…"

The possum winks, placing her hands on Kane's bare and fuzzy chest. "I've been wantin' this since y'all dropped yer car off."

The feline's expression, in response to her advances, turns from confused to very interested. "Well, that'd certainly put me in a better mood… Do you have or want protection? I don't usually keep condoms-"

Smoky laughs. "I'm infertile, hun. No risk here!"

There's a momentary pause, then with an eager growl in his throat, Kane responds "Well then, what are we waiting for?"

Chuckling, the possum heads to the front door of her garage, locking the door and flipping the sign to Closed, before leading the cheetah through the back door into her home.

"Tell ya what," she says with a grin, "impress me, and I'll knock a bit off your charge – Sound good?"

This gets Kane to purr, growling softly. "Ohh, you'd better hold on then; I'm gonna fuck that discount out of you."

"I'm gonna hold ya to that."

Without wasting any more time, the two of them strip completely naked – Smoky standing bare with her shorter, feminine figure, while Kane's toned, muscular body and impressive eleven-inch-long humanoid cock are on full display!

"Ooh, y'all really are quite a big boy, ain't ya?"

The possum steps close and places her hand around the two-inch-thick shaft, feeling it pulse in her hand as she softly strokes it. "Mmmh, I can't wait to feel this inside me…"

"Nor can I. In fact…" Kane grins, pressing forward to prod his tip against her vulva. "…I'm done waiting."

Smoky lifts a leg, placing it on the sofa to give him easier access. "Me too – Go for it, big guy."

The cheetah doesn't need to be told twice! He presses the head against her moist labia, rubbing some of his leaking precum onto it, before he thrusts forward, jamming a good three inches inside her pussy in one go!

"Nhhf!"

Smoky leans forward, holding Kane by his shoulders, while he shudders upon feeling her tight lavender walls around his cock.

"Hoo… You're not as warm as I expected… But very tight…"

As he presses himself deeper, testing the waters with her, the possum chuckles. "It's my natural body temperature. Possums have cooler temperatures than most mammals – I'm a chill eighty Fahrenheit!"

"Mhhf, didn't ask for a science lesson," Kane says with a chuckle, "but let's see if I can warm you up!"

The feline pills back about an inch before shoving another two inside, making Smoky moan adorably. And after this, he stops taking it gently and instead withdraws to thrust deeply in again, settling into a quick and firm rhythm for her!

"Hff… Nnn… You feel… So good, Smoky…"

"Hahh… S-So do you… Big boy… And I… Nngh… I bet this… Will feel… Even better…"

Before Kane has a chance to ask what she means, he gasps as he feels something wrapping around his heavy balls – Glancing down, he finds the possum's tail coiling gently around them, the tip caressing those sensitive orbs!

"Fuhh… Nnhf… Hoo…" The feline shudders deeply, the sensations truly amazing for him! "You're… You're full of surprises, aren't you?"

"Mmm, just… Just a dexterous tail… And a know-how for how to… How to please a guy…"

As Smoky fondles the cheetah's balls with her tail, he drives deeper still into her deep and tight tunnel, enough to make her belly bulge faintly from his sheer size!

Despite the pleasure and his roughness, Kane is at least attentive enough not to go too deep and risk hurting her. He's mindful not to hit her cervix, even though he has a few inches of cock still outside her. He doesn't want to ruin the moment, after all! He's content to thrust what he's able to inside her – Albeit nice and firmly.

Smoky, meanwhile, finds his current actions perfect! She shivers as he pounds into her pussy like this, every thrust of his hips causing a wet schllik to sound out. The thick cock spreading her tight insides so perfectly makes her shudder, holding tightly to his strong body for support.

And all the while, her tail continues to hold, caress, and gingerly squeeze his balls, helping to build the pleasure even further for him – And in turn, encouraging him to go even harder and faster as he builds ever closer toward his peak!

"Mhhf… K-Keep squeezing me like that, Smoky…"

The possum breathlessly replies "Nngh… With my tail, or my vag?"

A chuckle escapes Kane as he says "Yes!"

The cheetah's arms wrap around Smoky's chest to hold her tightly, making her gasp as he rams deeply and quickly into her. His cock throbs, pulsing as a sign of imminent release, and he growls out "L-Last chance… I'm almost there… Still want it in you?"

Smoky makes an exaggerated groan of mock-annoyance and shoots back "Oh, quit bullshitting me, Kane, and pump my womb full of cum already!"

"Heh, you got it!"

The feline moves his upper arm above her chest to hold her by her shoulders, keeping her in a tight grip as though to ensure she wouldn't get away from him. He thrusts once, twice, three times, before pressing as deeply as he can comfortably reach! His tip damn near pokes her cervix as he shudders, letting loose a torrent of hot, raw cheetah cum deep into the possum!

The possum chokes out a noise through the tight grip, still able to breathe but not able to speak, as she feels her tunnel clenching around Kane's cock, her own climax hitting her like a truck! Her tail squeezes those balls nice and snugly, encouraging them to let out everything they have into her, while her own fluids pour out of her and cover Kane's shaft and groin.

Kane's climax lasts a good ten or fifteen seconds, rope after rope of hot cum erupting into the possum as she takes everything he gives her. Her belly expands, bloating with the sheer volume of the load he's letting out – Even if she can't actually get pregnant, he's certainly making her look like she is!

Eventually, the flow subsides once her belly is about the size of a watermelon (bigger than his balls, but neither of them seem to care enough to question it). Smoky shudders, practically collapsing onto the still-standing Kane as she huffs and pants to catch her breath.

"Hoo… Fuh… Hahh… Gah… I've… I've not been… Fucked like that… In far too long…"

"Heheh… Happy you enjoyed it, Smoky." Kane chuckles, easing them both onto the sofa, his hands moving to caress her full belly.

"So, about that discount…"
