SCENARIO ONE

The gym is quiet this time of day. Late afternoon sunlight streams through the tall floor-to-ceiling windows, casting long golden rectangles across the polished yellow floor. The space is clean and open — a few rolled-up exercise mats, a bright blue stability ball resting near the glass, a simple weight bench with a pink pad, and racks of dumbbells lined neatly against the far wall. The air smells faintly of clean rubber, metal, and the residual scent of earlier workouts.

The door opens with a soft click.

Ruby Rose steps inside, her sneakers squeaking lightly against the floor. She’s dressed for training: a tight white crop top with bold red lettering that spells RWBY across her chest and a large number 1 centered right between her breasts. The thin fabric clings to her surprisingly full, soft tits, the neckline dipping just low enough to show a hint of cleavage, while the cropped hem leaves her entire toned midriff bare. Matching red athletic shorts sit high on her hips, the material stretching snugly over the round curve of her ass and riding up slightly along her smooth, pale thighs with every step. Black compression sleeves cover both arms from wrist to mid-bicep, contrasting against her fair skin. Her short black hair, tipped with distinctive red, frames a youthful, open face. Bright silver eyes scan the room before locking onto you.

She walks forward with that signature energetic bounce — the same one she used to have when charging into battle — and stops a few steps away. A warm, slightly nervous smile spreads across her face, cheeks already carrying a faint pink tint from either excitement or the walk over.

“HEY! You must be the personal trainer Yang was talking about!”

Her voice is cheerful, a little higher than average, and full of genuine eagerness. There’s no suspicion in it at all — just pure trust in her sister’s recommendation. She plants both hands on her hips, the motion unconsciously pushing her chest forward. The tight white top stretches even tighter across her full breasts, the fabric pulling against the soft weight of them and making the red number 1 distort slightly with the movement.

“Okay, I’m ready to work up a sweat!” she continues, silver eyes sparkling with determination. “Where do we start?”

She looks up at you expectantly, shifting her weight from one foot to the other, completely unaware of how the soft bounce of her breasts or the way her shorts cling to her ass might be affecting the person she’s asking. In her mind this is just another training session — a chance to get stronger, just like Yang promised.

SCENARIO TWO

Before Ruby can even finish asking where to start, you’re already moving her.

One moment she’s standing there with her hands on her hips, silver eyes bright and eager, completely focused on the idea of a normal training session. The next, strong hands are guiding — then firmly placing — her onto the weight bench. Her back hits the padded surface. Her legs are spread wide, sneakers still on, the tight red shorts yanked hard to the side (or pulled clean down her thighs). The white crop top is shoved roughly up over her full breasts, the soft, pale mounds spilling free into the cool gym air, nipples already tightening from the sudden exposure and the rush of adrenaline.

Her hands fly up to the barbell above her head. Instinctively she grips it, black compression sleeves stretching as her fingers wrap tightly around the metal for support.

You push into her in one smooth, deep thrust.

Ruby’s silver eyes fly wide open. A sharp, startled gasp tears from her throat as her tight, inexperienced pussy stretches around the thick length of your cock. Her back arches hard off the bench, bare breasts jiggling from the force of the sudden penetration, the soft flesh bouncing and settling with every inch you sink into her. A deep, vivid flush explodes across her cheeks and races down her neck and the upper slopes of her chest. Her short black-and-red hair fans out against the bench, a few strands already sticking to her forehead.

“T-This isn’t what I had in mind...!”

Her voice is high, shaky, and full of pure disbelief. She tightens her grip on the barbell until her knuckles turn white, arms trembling slightly under the black sleeves. Her legs quiver on either side of your hips, thighs flexing as she tries — and fails — to process how quickly everything changed. The wet, intimate sound of your cock sliding in and out of her freshly spread cunt fills the quiet gym, each thrust pushing a little deeper, stretching her a little more.

Every movement makes her soft breasts bounce and sway. Her silver eyes flutter, struggling to stay focused on anything. She’s already breathing hard, chest rising and falling rapidly, completely overwhelmed by the sudden intensity and the raw, unprotected feeling of being filled so completely on what was supposed to be a simple training session.

SCENARIO THREE

You don’t slow down.

Ruby’s hands stay locked around the barbell above her head, black compression sleeves stretched tight as her arms flex with every thrust. Her legs are spread wide on either side of the bench, red sneakers still on, the tight red shorts pulled completely out of the way. Her white crop top remains shoved up over her full breasts, the soft pale mounds bouncing and jiggling hard with every deep stroke. The red RWBY 1 lettering is wrinkled and stretched across the fabric bunched above them.

You’re buried inside her to the hilt, fucking her in steady, powerful thrusts that make the bench creak softly beneath her. The wet, rhythmic plap-plap-plap of your hips meeting hers fills the quiet gym. Her tight, inexperienced walls clench and flutter around your cock with every stroke, still adjusting to being stretched so suddenly and so completely.

Ruby’s silver eyes are wide and glassy, a deep flush burning across her cheeks and down her neck. Her short black-and-red hair sticks to her forehead and the sides of her face from the growing heat. Every time you bottom out she lets out a shaky little gasp, her back arching slightly off the bench, bare breasts swaying with the force.

“At least wear a condom!” she manages between breaths, voice high and strained. The protest sounds more desperate than angry — like she’s still trying to hold onto the idea that this is somehow still a normal training session, even while she’s being thoroughly taken raw on the weight bench.

Her fingers tighten harder around the barbell. Her thighs tremble. The soft, wet sound of your cock sliding in and out of her freshly stretched pussy only grows louder as she starts to get wetter despite her words. She’s clearly overwhelmed, body reacting even as her mind tries to catch up to how completely the situation has changed.

SCENARIO FOUR

You keep going, deeper and harder.

Ruby’s legs stay spread wide on the bench, her soft thighs trembling with every powerful thrust. From this angle her round ass and the stretched, glistening lips of her pussy are fully on display, your cock disappearing into her over and over with wet, heavy plaps. Thick juices already coat your shaft and drip down onto the bench beneath her. Her white crop top is still shoved up, full breasts bouncing hard with every impact, the red 1 wrinkled and forgotten above them.

Her silver eyes are wide and glassy, the flush on her face even deeper now. She grips the barbell tighter, black sleeves flexing as her arms shake. Every time you bottom out she lets out a high, shaky whimper, her tight walls fluttering and squeezing around you like she’s trying (and failing) to adjust to the relentless pace.

“Today’s not safe...!” she gasps, voice cracking with a mix of panic and reluctant arousal. The words come out between thrusts, breathless and desperate. She’s clearly still trying to warn you, still trying to hold onto some last bit of control even as her body betrays her — growing wetter, clenching harder, taking every inch you give her.

You don’t slow down, but at first. The wet sound of raw sex fills the gym. Ruby’s short black-and-red hair sticks to her flushed cheeks, her chest rising and falling rapidly, bare breasts swaying with every deep stroke as she continues to take it all.

SCENARIO FIVE

You pick up the pace without warning.

Ruby’s silver eyes fly wider as the thrusts suddenly grow harder and faster. The wet plap-plap-plap of your hips slamming against her becomes louder, more urgent, echoing through the quiet gym. Her full bare breasts bounce wildly with every impact, the soft flesh jiggling hard. Her tight, inexperienced walls clench around your cock in startled little spasms, still struggling to adjust to being taken this roughly and this deep.

“Huh!? Slow down!” she cries out, voice high and panicked while she moans obscenely.

Her hands move from the barbell above her head to your arms, black compression sleeves stretched tight as her arms tremble from the force. Every hard thrust rocks her body on the bench, forcing shaky gasps from her throat. The flush on her face burns even hotter, spreading down her neck and across the upper slopes of her bouncing breasts. Her short black-and-red hair sticks to her damp cheeks.

You don’t slow down. Instead you drive into her even deeper, the head of your cock kissing against her cervix with every stroke. A faint internal pressure builds — the kind that makes her silver eyes go glassy and her protests start to lose their strength. Her pussy flutters and squeezes around you, growing wetter despite her words, as the relentless pace continues to overwhelm her.

SCENARIO SIX

You don’t slow down. If anything, you drive into her harder.

Ruby’s silver eyes are wide and glassy, her breath coming in short, panicked gasps as the wet plap-plap-plap of your hips slamming against hers fills the gym. Her full bare breasts bounce wildly with every deep thrust, the soft pale flesh jiggling hard, nipples tight and flushed. The white crop top is still shoved up above them, the red RWBY 1 lettering wrinkled and forgotten. Her black compression sleeves are stretched tight as her hands grip the barbell above her head for dear life, arms trembling from the force.

“Don’t cum inside me...’

Her legs stay spread wide on the bench, sneakers still on, thighs quivering. Every powerful stroke sinks you to the hilt, the head of your cock kissing firmly against her cervix. The wet, filthy sound of her tight, inexperienced pussy taking you over and over grows louder as she gets wetter despite herself. Thick juices coat your shaft and drip down onto the bench beneath her.

Ruby’s face is burning red. Her short black-and-red hair sticks to her damp cheeks and forehead. She can feel how deep you are — how every thrust presses right against the entrance to her womb.

“If you do,” she gasps, voice high and cracking with real panic, “I’ll get pregnant...!”

The words come out broken between thrusts, her silver eyes locked on yours in a last desperate warning. Her walls flutter and clench around you in tight, rhythmic spasms, still trying (and failing) to adjust to the relentless pace. Her back arches off the bench, bare breasts thrusting upward, as you keep driving into her without mercy.

You don’t pull out.

You bury yourself to the absolute hilt and cum. Thick, heavy ropes of cum explode deep inside her in long, powerful spurts — so much that the pressure against her cervix is immediate and intense. Ruby’s mouth falls open in a sharp, broken cry.

“OOH!!”

Her entire body shudders hard. Her tight walls clamp down around your cock in frantic, milking contractions as you pump load after load straight into her womb. The internal flood is massive — hot, thick cum flooding her completely, the excess already starting to leak out around the base of your shaft in messy white rivulets that drip down onto the bench. The wet sound of it is filthy and loud in the quiet gym.

Ruby’s silver eyes go wide and unfocused, her back arching harder, bare breasts heaving as she takes every pulse. Her hands grip the barbell so tightly her knuckles turn white. Her thighs tremble violently on either side of your hips. She can feel every thick spurt hitting deep, filling her, breeding her exactly like she warned you it would.

You keep grinding against her cervix through the entire orgasm, forcing every last drop as deep as it will go while her pussy flutters and squeezes around you in overwhelmed, rhythmic clenches. By the time the last pulses fade, Ruby is left panting, flushed, and completely full — a thick mess of cum already beginning to leak from her stretched, freshly bred cunt as her legs slowly wrap around your waist to keep you in.

“I’ll get pregnant...”

SCENARIO SEVEN

Ruby is still trembling beneath you.

Your cock remains buried deep inside her, the thick load you just pumped into her womb making every small movement feel heavier, wetter. Hot cum is already leaking out around your shaft in slow, messy rivulets that drip down onto the bench. Her tight walls flutter weakly around you, still spasming from the intense creampie, sensitive and overstimulated.

Her silver eyes are half-lidded and glassy, the earlier panic softened into something dazed and overwhelmed. A deep flush still burns across her cheeks and down her neck. Her full bare breasts rise and fall with every shaky breath, the white crop top still shoved up above them. The black compression sleeves are damp with sweat as her hands stay loosely wrapped around your arms, no longer gripping with panic — just holding on.’

You start moving again, slower this time, grinding deep so she can feel the cum shifting inside her with every stroke. The wet sound is filthier now — thick and slick from the load already stuffing her.

Ruby’s lips part. A soft, breathless sound escapes her. “Let’s-mmm...keep going...”

Her voice is quiet, almost hesitant, but she doesn’t tell you to stop. Her thighs twitch on either side of your hips. Her silver eyes flutter as you push back in to the hilt, forcing more of the mess to leak out around you. She’s still so full, still so sensitive, and yet she’s no longer fighting it. The protests have faded into quiet, shaky acceptance as she lies there on the bench and takes every slow, deep thrust while your cum continues to drip from her freshly bred pussy.

SCENARIO EIGHT

Later.

Ruby sits alone on the closed toilet lid in a small, tiled bathroom. She’s changed into a simple dark red tank top that clings to her full breasts and leaves her midriff bare. Her short black-and-red hair is a little messy. Her silver eyes are downcast, a soft flush still lingering on her cheeks.

In both hands she holds a white-and-red pregnancy test.

She stares at the result window for a long moment.

Two clear lines.

Positive.

Her lips part slightly. A quiet, shaky breath leaves her. “...Haa...”

She keeps looking at the test, silver eyes wide and glassy. The flush on her face deepens. For a few seconds she just sits there, processing it — the memory of the gym, the way she’d been pinned and filled, the thick heat that had flooded her womb, and the quiet “keep going” she had eventually whispered.

Slowly, her expression softens from pure shock into something quieter. Resigned. Almost accepting.

She closes her eyes, cheeks still pink, and lets out another soft, shaky breath as the reality settles over her.

She’s pregnant.

“Damn it Yang!”
