SCENARIO ONE

The gym is nearly empty this late. Overhead fluorescent lights hum softly against the teal-tiled ceiling, casting long shadows across the rubber mats and weight racks. Floor-to-ceiling windows dominate one entire wall, the city lights glittering far below under a dark blue night sky. The air smells faintly of metal, rubber, and clean sweat.

You’re mid-set or just finishing when you notice her.

Yang Xiao Long is across the room, finishing a heavy compound movement. She racks the weight with a controlled exhale, the plates clanking softly. Her body is a study in power and curves: long, powerful legs, thick thighs that flex with every step, a narrow waist that flares into wide hips and a full, round ass barely contained by a pair of tight yellow panties that dig slightly into soft flesh. Her abs are sharply defined, glistening with a light sheen of sweat that trails down between them and disappears beneath the waistband of those panties.

She’s wearing a form-fitting yellow-and-white sports bra that strains across her heavy chest, the fabric stretched tight enough that the underside of her breasts peeks out with every breath. The number “4” and the words “Xiao Long” are printed in bold yellow across the back. Black compression sleeves cover both arms from wrist to bicep; the left one is ordinary fabric, but the right is clearly fitted over the sleek, high-tech prosthetic that replaced the arm she lost years ago. The metal of the prosthetic catches the light whenever she moves. Her long blonde hair is pulled into a high, messy ponytail that sways with every motion, a few loose strands sticking to the damp skin of her neck and collarbones. Purple eyes, bright and sharp, scan the room—

—and land on you.

She doesn’t look away.

Yang straightens fully, rolling one shoulder (the prosthetic one moves with perfect, unnatural smoothness). A slow, interested grin spreads across her face. She raises her left hand in a casual wave, the other settling on the curve of her hip, fingers resting against bare skin just above the waistband of her panties.

“Oh, yo.”

She starts walking toward you, hips swaying with easy confidence, the thin yellow fabric of her panties shifting with every step. The closer she gets, the clearer the details become: the way sweat beads along her cleavage, the faint red marks left by the tight sports bra straps, the powerful flex of her thighs, the way her prosthetic fingers curl slightly as she looks you over with open appreciation.

She stops a few feet away, head tilted, purple eyes traveling slowly down your body and back up again.

“I’ve been looking for someone to train with,” she says, voice low and warm, “and you seem pretty strong...”

A small, knowing smile tugs at her lips. “...pretty strong. Whaddya say!?”

She shifts her weight to one leg, the motion making her breasts sway heavily inside the strained sports bra, and adds with clear intent: “Let’s make some results!”

SCENARIO TWO

Yang doesn’t wait for a verbal answer.

The moment you step closer — or simply don’t back away — she closes the remaining distance, prosthetic hand settling firmly on your chest while her other hand slides down to grip the front of your shorts. Her purple eyes stay locked on yours, that same confident, hungry smile never leaving her face.

“Good,” she murmurs.

In one smooth motion she turns, presenting her back to you, and bends forward over the nearest weight bench. The yellow panties stretch tight across her full, round ass as she arches, the thin fabric disappearing between her cheeks. Her long blonde ponytail falls over one shoulder. The high-tech prosthetic braces against the bench for support while her other hand reaches back, fingers curling in clear invitation.

You take the offer.

The moment you push the yellow panties aside and sink into her, Yang lets out a sharp, throaty sound of pure satisfaction. Her walls clamp down hot and slick around you — no hesitation, no barrier, nothing between you.

“Oh, yeah... that’s it—”

A wet plap echoes through the empty gym as your hips meet hers. You gather her blonde ponytail in one hand and pull, forcing her back into a deeper arch. Yang moans louder, the sound vibrating through her chest. The sports bra is still on, but the way she’s bent makes her heavy breasts strain against the yellow-and-white fabric, the undersides visible with every thrust.

She looks back over her shoulder, cheeks already flushed, purple eyes half-lidded with pleasure.

“Raw cock feels so damn good on risky days~!”

Another hard thrust drives a louder moan from her. Her prosthetic fingers dig into the bench padding. Sweat glistens down the deep curve of her spine, trailing between the dimples just above her ass. The black compression sleeve on her left arm flexes as she braces herself, while the sleek metal of the prosthetic remains steady and strong beneath her weight.

Yang pushes back to meet every stroke, greedy and unashamed, the wet sounds of skin on skin filling the quiet gym. “Oh god... it feels so damn good...”

SCENARIO THREE

You keep pounding into Yang from behind, the wet plap-plap-plap of your hips meeting her full, jiggling ass echoing through the empty gym. Her yellow panties are still yanked to the side, stretched tight around one thick thigh. The sports bra has ridden up, leaving the bold yellow “Xiao Long” and the number 4 stamped clearly across her upper back with every hard thrust. Sweat runs down the deep curve of her spine and pools in the dimples just above her ass. Her prosthetic arm braces solidly against the bench while her other hand grips the edge for leverage.

Yang looks back over her shoulder, cheeks flushed, purple eyes half-lidded and gleaming with heat. A wicked little smile curves her lips even as another deep stroke forces a soft, shaky moan from her throat.

“Which reminds me...” she pants, voice low and teasing. “Let me know when you’re about to bust, okay?”

She deliberately squeezes around you, walls fluttering hot and greedy.

“We wouldn’t want any accidents...”

The words are barely out of her mouth.

Your hips slam forward one last time and you bury yourself to the hilt. Thick ropes of cum explode deep inside her, flooding her cunt in heavy, pulsing spurts. You can feel every spurt painting her walls, the pressure building as you keep pumping more and more of it straight into her womb. Yang’s eyes go wide for a split second. Her mouth falls open in a sharp, surprised gasp as the first heavy load hits her cervix and keeps coming.

Hot cum overflows almost immediately, leaking out around your cock in thick white rivulets that drip down her thighs and onto the bench. You don’t pull out. You just keep grinding deep, forcing every last drop as far inside her as it will go while her pussy milks you greedily, fluttering and clenching around the thick shaft still buried in her.

Yang’s long blonde ponytail hangs messy over one shoulder. Her heavy breasts sway heavily beneath her with every residual throb of your cock. The black compression sleeve on her left arm flexes as her fingers dig into the padding. The sleek metal of her prosthetic stays locked steady, supporting her weight even as her legs tremble.

A low, almost disbelieving laugh slips out of her as the last thick pulses fill her.

“...Oh,” she breathes, voice husky and suddenly very aware of the warm, heavy feeling spreading deep in her belly. “I get it now.”

SCENARIO FOUR

You’re still buried to the hilt inside her when Yang’s eyes widen.

The thick, heavy load you just pumped into her is still pulsing out of your cock in residual throbs, flooding her already-stuffed cunt. Thick white cum is already leaking around the base of your shaft in messy rivulets, trailing down her inner thighs and dripping onto the bench beneath her. Her walls keep fluttering and milking you, greedy little squeezes that try to keep every drop locked inside her womb.

“...Oh,” she breathes, voice low and suddenly very aware of the warm, heavy fullness spreading deep in her belly. “I get it now.”

+She doesn’t pull off.*

Instead Yang slowly straightens while still impaled on you, the motion making more of your cum spill out around your cock in wet, sticky strands. She turns just enough to look back at you over one shoulder, long blonde ponytail sliding across her sweat-slick back. Her purple eyes are half-lidded, cheeks flushed dark, and a slow, wicked smile spreads across her face as she deliberately rolls her hips, grinding down so you can feel exactly how full she is.

“You wanna knock me up, huh?”

The words come out almost playful, but there’s real heat underneath them — and something darker, hungrier. She reaches back with her flesh hand and grips your thigh, nails digging in, while the sleek metal of her prosthetic braces against the bench for leverage. Her heavy breasts sway freely now; the yellow-and-white sports bra has been yanked down beneath them, leaving both soft, full tits bare and bouncing with every small movement. Sweat glistens between them and trails down over her toned abs.

Yang pushes back onto you again, taking every inch until her soft, round ass is pressed flush against your hips. A soft, satisfied moan slips out of her as she feels the mess of cum inside her shift with the motion.

“Well... why didn’t you say so?”

She starts moving properly now — slow, deliberate rolls of her hips that drag her slick, cum-filled walls up and down your length. Every downward grind forces more of your first load to leak out around you in thick white streaks that paint her thighs and the bench. The wet, filthy sound of it fills the quiet gym.

Her eyes stay locked on yours the whole time, purple irises dark with arousal, that same cocky little smile never leaving her lips even as her breathing grows heavier.

“In that case,” she says, voice dropping lower, almost a growl, “you’re gonna need to come at me a lot more.”

She lifts up until just the head is still inside her — letting a thick glob of your cum drip free — then drops back down hard, taking you to the base in one wet, perfect stroke. Her heavy tits bounce hard with the impact. The black compression sleeve on her left arm flexes as her fingers dig into the padding. The high-tech prosthetic stays rock-steady, supporting her weight while she starts to ride you properly, already working toward the next load she wants buried deep in her womb.

SCENARIO FIVE

Yang doesn’t give you even a second to recover.

The moment the words leave her mouth she starts riding you like she means it — hard, deep, and completely shameless. Her powerful thighs flex and strain as she lifts almost all the way off your cock, the thick, sticky ropes of your first load stretching between you in wet, glistening strands before she drops back down with a heavy, wet plap. The impact sends her full, bare breasts bouncing hard, the soft, heavy flesh jiggling and swaying, nipples tight and flushed dark from arousal. Sweat runs freely down the deep valley between them, trailing over the sharp lines of her abs and disappearing into the messy junction where your bodies meet.

She’s still so full of you. Every upward stroke forces more of that thick white cum to spill out around your shaft in messy rivulets that coat her inner thighs, drip down over your balls, and pool on the bench beneath her. The wet, filthy sounds of it fill the empty gym — the wet squelch of a creampie being fucked deeper, the rhythmic slap of her soft ass against your hips, Yang’s low, needy moans that grow louder with every bounce.

Her purple eyes stay locked on yours... until they start to change.

A faint red glow bleeds into the irises, growing stronger and hotter with every hard drop of her hips. Her breathing turns heavier, more ragged, almost desperate. The black compression sleeve on her left arm flexes tightly as her fingers dig into your chest or the edge of the bench for leverage. The sleek, high-tech metal of her prosthetic stays rock-steady, supporting her weight with perfect mechanical strength even as she starts slamming herself down harder, chasing the next load with zero restraint.

“C’mon...” she pants, voice low and rough, the red in her eyes brightening until they’re glowing. “Pump me full—”

She grinds down hard at the bottom of a stroke, rolling her hips in a slow, filthy circle so the head of your cock kisses deep against her cervix. The leftover cum already inside her is forced even deeper, a thick glob of it leaking out around you in a hot, sticky rush that runs down your shaft and over your balls. Yang’s walls flutter and squeeze around you the entire time — greedy, rhythmic clenches that try to milk another load straight into her womb.

Her long blonde hair is coming completely loose from the ponytail now, wild strands sticking to the sweat-damp skin of her neck, shoulders, and the upper curves of her bouncing breasts. The yellow-and-white sports bra is still shoved down beneath them, completely forgotten, leaving both heavy tits free to bounce and sway with every brutal drop of her hips. You can see the faint red marks left by the tight fabric earlier, and the way her nipples tighten further every time she takes you to the base.

Yang’s red eyes lock onto yours, burning with pure, open need. There’s no teasing left in her expression now — just raw, hungry desperation and that same cocky little smile that says she knows exactly what she wants.

“I want your fucking baby.”

She drops down hard again, taking every thick inch in one wet, perfect stroke, and holds herself there, grinding, squeezing, trying to force you deeper. More of your first load spills out around the base of your cock in thick white streaks that paint her soft thighs and the bench. The scent of sex and sweat is heavy in the air. Her prosthetic arm stays locked steady, supporting her while her flesh hand reaches back to grip your thigh, nails digging in as she starts to bounce again — faster, harder, determined to get exactly what she’s asking for.

SCENARIO SIX

Yang’s glowing red eyes are locked on yours when you finally break.

You drive up into her one last time with everything you have, burying yourself to the absolute hilt as the orgasm rips through you like a detonation. Thick, heavy ropes of cum explode deep inside her womb in long, powerful spurts — so much volume that you can feel the pressure building against her cervix with every pulse. The first massive load hits her so hard that Yang’s mouth falls open in a sharp, broken cry, her back arching hard, heavy bare breasts thrusting forward as her walls clamp down around your cock in a series of intense, milking contractions.

“Breed—!”

The word cuts off into a high, shaky moan as you keep pumping more into her. Cum floods her already-stuffed cunt in thick, endless spurts, the pressure so intense that it starts overflowing almost immediately. Hot white cream spills out around the base of your shaft in heavy rivulets, pouring down over your balls, coating her soft inner thighs, and dripping onto the bench in messy white streaks. The wet, filthy sound of it is loud in the quiet gym — the wet squelch of a womb being completely filled, the soft slap of her ass against your hips with every residual throb.

Yang’s entire body shudders. Her powerful thighs tremble violently around you. The black compression sleeve on her left arm is stretched tight as her fingers dig hard into your chest, nails biting skin. The sleek, high-tech metal of her prosthetic stays locked and steady, supporting her weight even as her legs threaten to give out. Her long blonde hair is a wild mess, sticking to the sweat-slick skin of her neck, shoulders, and the upper curves of her bouncing breasts. Those heavy tits sway and jiggle with every powerful pulse of your cock still buried inside her, nipples tight and flushed dark.

You don’t pull out. You keep grinding deep, forcing every last thick rope as far into her womb as it will go while her pussy flutters and squeezes around you in greedy, rhythmic clenches. The internal pressure is intense — you can feel how completely you’ve packed her full. Thick white cum keeps leaking out around your shaft in continuous sticky streams, the excess forced out by the sheer volume still pumping into her.

Yang’s glowing red eyes slowly flutter. The fierce light in them softens and fades as the last heavy pulses empty into her, the red bleeding back into her normal purple. She stays seated all the way down on your cock, chest heaving, a slow, dazed, utterly wrecked smile spreading across her flushed face. Her breath comes in short, shaky pants. More of your load continues to leak out of her in thick white rivulets that run down her soft thighs and drip onto the bench.

“...Fuck,” she breathes, voice rough, hoarse, and thick with satisfaction. “That was good...”

She rolls her hips once — slow, lazy, and filthy — feeling the massive, heavy load shift deep inside her womb. The motion forces another thick glob of cum to spill out around your cock and trail down over your balls. Her purple eyes are half-lidded and hazy with pure post-orgasm bliss. She leans forward slightly, letting her heavy bare breasts hang and brush against your chest, the soft warm weight of them pressing into you. Sweat drips from her collarbones onto your skin.

Yang lets out a low, contented little laugh, the sound almost giddy. “I love being a slut~”

She stays right there, still fully impaled on you, walls still gently fluttering around the thick shaft that just finished breeding her, the mess of your combined fluids coating everything between her thighs in a glossy, sticky sheen.

SCENARIO SEVEN

Time has passed since that night.

You’re back in the same gym, the late-hour quiet broken only by the low hum of the fluorescent lights and the distant city glow beyond the floor-to-ceiling windows. The air still carries that faint scent of rubber, metal, and clean sweat. You’re just finished a set as you are now drinking water, when Yang suddenly walks in like she owns the place.

She’s changed outfits. A tight yellow crop top with a bold white number 2 stretched across her full chest, the fabric hugging every soft, heavy curve. Black panties sit low on her wide hips, the thin material clinging to the round swell of her ass. The same black compression sleeves cover both arms — one ordinary fabric, the other fitted over the sleek high-tech prosthetic. Her long blonde hair is pulled into a high ponytail that sways with every confident step. Her body still looks powerful and toned... but there’s a soft, satisfied glow to her skin, a subtle fullness in her breasts, and a quiet, almost smug contentment in the way she carries herself.

Purple eyes light up the moment they find you.

“Yo!” she calls, voice bright and playful. She walks straight toward you with that familiar hip-swaying stride, heavy breasts shifting and bouncing lightly under the tight yellow fabric. In one hand she holds something small and yellow.

She stops right in front of you, close enough that you can catch the warm scent of her skin and the faint trace of her shampoo. A wide, wicked grin spreads across her face as she lifts the pregnancy test between you like a trophy.

“Ready for those results?”

She flips it around so the two bold lines are unmistakable.

“Ta-daaa~!”

Yang’s grin turns downright filthy. She leans in, the soft weight of her breasts brushing against your arm, the heat of her body almost pressing into yours. Her voice drops into that low, sultry register you remember from the night she made you fill her.

“Nice work, daddy~”

She doesn’t pull back. Instead she rests her free hand on her still-flat stomach, fingers splaying possessively over the toned abs she’s about to lose. The prosthetic arm settles lightly on your shoulder, metal cool against your skin, while her flesh fingers stroke slowly across her midriff like she’s already imagining the changes to come.

“But don’t you think you owe me a few favors,” she continues, voice soft and teasing, “since I’m gonna lose my abs in a few months thanks to you?”

She digs into the waistband of her black panties and pulls out her scroll. The screen lights up with a string of messages — familiar names, familiar faces. Blake asking about personal trainers. Ruby mentioning she needs to blow off steam. Weiss looking for a physical instructor who can keep up with her standards. Yang tilts the phone so you can see every word, purple eyes sparkling with pure mischief.

“I might know how you could make it up to me~”

She steps even closer, the warm curve of her body finally pressing against yours. Her heavy breasts crush softly against your chest. The pregnancy test dangles from her fingers between you like a trophy. Her prosthetic hand stays on your shoulder while the other remains on her stomach, right over the place you filled so thoroughly that night — the place that is now carrying the results of everything you did to her.

Yang’s smile is pure Yang — cocky, affectionate, and already planning the next round of “training.”
