Short Story: Possession by a Woman in a Bikini at the Summer Pool (Patreon)

The chlorine scent lingers in the summer air by the poolside, tickling my nose. The white tiled floor glares under the sun, glinting off the tanned skin of women around me. Hiding in the shadows of the locker room, I lick my lips as I stealthily watch the girls in their swimsuits.

"Ah… what a perfect hunting ground…"

I possess a special ability—I can invade and take over other people's bodies. Today, I came to this public pool with the intention of thoroughly enjoying a woman's body.

It seems far livelier here on a holiday afternoon than I expected.

Women walk past the changing rooms, and every time they do, glimpses of swimsuit straps and sweat-dampened backs peek out from fluttering towels. A group of seemingly college-aged girls, around twenty, giggle loudly as they chat. One in particular catches my eye—a long-haired girl in a tiny pink bikini. Her narrow waist, firm ass, and the contrast with her innocent face is irresistible.

I slip into a toilet stall. Here, no one will disturb me as I initiate possession. Sitting on the seat, I close my eyes and focus. My target—that pink bikini girl from earlier. In my mind, I cement the image of her thin swimsuit strap on the verge of snapping and her collarbones glistening with sweat.

"That girl's body… I'll make it mine…"

The sensation of my consciousness slipping away from my body—no matter how many times I do this, it never gets easier. Floating in that hazy, detached feeling, I stretch my awareness toward the locker room.

The pink bikini girl is blow-drying her hair. A perfect chance—she’s staying still.

"Ahk—!"

With a dizzying shift, my vision changes. Looking down, my hands are small, pale, and manicured. And most of all, the snug bite of the swimsuit around my chest feels incredible.

"Nrhh… I'm in…"

I barely whisper, just loud enough not to draw attention. The reflection in the mirror is unmistakably the girl I was just watching earlier. Her long lashes, plump lips. The pink bikini feels even tighter now. The warmth of her true owner's body pulses against me, arousal rising hot inside.

The locker room still has a few other women, but they’re all too absorbed in their own tasks to notice me. Now… let’s thoroughly explore this body. Starting with the sensation of this swimsuit first. Pinching the fabric between my fingers, I tug lightly—ugh, the soft, elastic resistance is intoxicating!

"Ah-ha… this girl’s tits are crazy soft…"

My palms gently cup her breasts, the pleasant weight filling my hands. When I flick my fingertips teasingly over the nipples, I barely choke back a gasp. The knowledge that people are nearby only spikes the thrill. Right—I should check the locker contents too. Her ID will tell me her name.

My hands tremble as I open her bag. I need to uncover this girl’s secrets now—!

Rummaging through the locker, I find a student ID. Amami Sugimoto, 20, third-year university student. Even her parents’ address is listed. I burn the details into memory—this info might prove useful later.

"Excuse me, can I use the dryer?"

A voice from behind nearly makes my heart leap out of my chest. I must’ve been in the way. I quickly shut the locker, my feigned sweet reply slipping out breathier than intended.

"…Go ahead."

Buzzing hair dryers fill the air as I hatch a plan. The shower stalls—I’ll have more privacy there. Sweat clings uncomfortably under my swimsuit, making a shower the perfect excuse.

Gathering her towel and body soap, I choose the stall at the very end. Pulling the curtain shut, I finally exhale. The steam-fogged mirror reflects Amami’s face—flushed, panting. This expression is mine now…

"Alright then…"

Slowly, I roll up the top of the bikini. The pressure leaving her stiffened nipples sends immediate shivers down my spine. Touching them directly shocks me—so much more sensitive than I imagined. When I knead them like wet sponges, my knees almost buckle.

"Ngh…! H-holy shit… Amami’s body—it’s crazy responsive…!"

And lower is even better. Her swimsuit bottoms are already drenched—so slick my fingers almost slip just brushing against her.

"Okay… time for the main event…"

Running shower water warms my fingers before I trace the outer folds. Her slit twitches against my touch. The thought of whatever dream the real Amami is having right now twists the heat in my gut tighter.

"Haah… S-so this is what her pussy’s like… dripping this much already…?"

Spreading her legs wider, I sandwich her clit between two fingers and rub in quick circles. Watching myself finger this body in the mirror is obscenely hot. The hand on my breast squeezes harder without thinking.

"A—ahhn~! N-no… th-this is… actually a g-girl’s… nnnh! I-I’m g-gonna… cum…!"

Her hips jerk wildly, the shower spray suddenly deafening. Water sounds echo from other stalls—someone could hear. But if I keep quiet… barely… Whimpers spill as I speed my fingers up.

"Mmn! Faster—! Wanna f-feel more… m-more of this… fuck…!"

Squelching fills the stall as two fingers plunge deeper inside. She’s clenching—tight, fluttering— so much that my eyes water. Holy shit, she’s throbbing—! Heat surges from my stomach like a flash flood.

"Uh—hng! Ah, ’m—’m gonna—! C-can’t—nnnAAAAH—!! ♡♡"

Something thick and wet pulses out from between my thighs.

"Are you okay? That was a weird sound…"

A knock jolts me back to reality—a young woman’s voice. Embarrassing… but god, it makes me hotter—!

"Y-yes! I’ll—ahh~!—b-be right out…!"

My hips twitch helplessly, my fingers still pinching her clit as I answer. How the hell am I supposed to leave like this…?!

Only when I hear footsteps fading do I slump in relief. Amami’s body shudders faintly, a thin trail of clear slickness dripping to the floor. No way… she—no, I—just squirted…?!

"Fuck… this body’s too damn good…♡"

Even as I hurriedly wipe myself down, my chest stays flushed. The lingering pleasure tingles—tempting me to rub her clit all over again. But lingering too long is risky. Slipping back into the swimsuit, I pause by the mirror on my way out.

Her face is flushed, lips glossy. Eyes lazy and sinful—a look drunk on pleasure. She—no, I—still wants more… but it’s time to move on.

Rushing back to the bathroom stall, I close my eyes and focus. The warmth of Amami’s body slowly fades, my mind peeling away from hers with a sticky, reluctant pull.

Back in my own body—slouched on the toilet seat in the men’s locker room—I grin. The ghost of her sensations lingers on my fingertips. The reality of being male again just sharpens my hunger.

This possession isn’t over. Not yet.

Back at the poolside, I scan for fresh prey. The girls shrieking on the waterslide, the woman catching her breath after swimming laps, the fit beauty doing aquatic acrobatics—all perfect.

"Mmm… I think I'll take that one…"

My gaze locks onto a woman gliding effortlessly through the water. Her turquoise swimsuit glints under the sun, her golden hair shining like liquid metal. When she surfaces, the elegant curve of her back and the cling of her bikini bottoms make my mouth water.

"Those movements… like a professional swimmer…"

I observe intently from the pool’s shadow. Definitely in her twenties. She swims alone—occasionally pausing at the edge to rest. The way she dabs sweat from her neck, the dip of her throat as she drinks—everything's obscene.

I watch her head to the changing room and bide my time. After five minutes, I dart into the restroom stall again. Sitting on the toilet, I conjure her image—golden hair, turquoise swimsuit. A tingle spreads through me. The sensation of untying those swimsuit strings, the droplets sliding down her neck—all mine soon.

"Let the possession begin…!"

That familiar floating sensation swallows me as my consciousness tears free, surging toward the changing room. She's there—wringing out her hair in front of the lockers. Perfect timing.

"—hk!"

My vision sharpens with a snap. Water clings to my skin, but it’s different now—warmer, stickier. When my eyes focus, strands of wet blonde hair swing into view. Whoa—taller than Amami…!

"H-heavy…!"

The weight on my chest is staggering. The swimsuit barely contains them—swaying, overflowing. Are these F-cups? Bigger?! Unbelievable.

Wasting no time, I reach for the ties at my sides. A front-fastening type? After some fumbling, they unravel—letting the swimsuit drop under sheer weight.

"Ohh—!"

In the mirror, these pillowy breasts glow peach-pink, nipples pale and painfully erect—from the cold, maybe? A tentative flick sends sparks shooting down my spine.

"Nngh… this body’s even better…!"

Palming both breasts at once, pleasure ripples through me. And that waist—snatched, leading down to a round, perky ass…! I sway in front of the mirror. The cold air pebbles my nipples tighter, each jolt of sensitivity electric.

"Nngh… So many people around, and here I am doing this…"

Women dry their hair and change clothes just steps away. If anyone glances over, my lewd act would be exposed instantly—yet that shoots the thrill higher.

Hooking fingers under the swimsuit’s bottom half, the stretched fabric reveals how snugly the bikini clings between her thighs. The thin material transmits every plush, overheated dip. My fingers freeze.

"Hah— just this feels… good enough already…?"

Rubbing her clit through the fabric, the taut nylon channels the pressure perfectly. In the mirror, only the swollen bulge at her crotch remains covered—the rest of me naked, sweat-slicked breasts swaying.

"Ahh… What if someone noticed…?"

The woman blow-drying her hair nearby might have just looked over. Heart pounding, I keep my expression neutral—while never breaking the circling friction. The heat coils lower with every pass.

"Hah… Just… a little more…"

This time, I tug the suit’s side aside just enough to expose skin—still hidden from others by my angled reflection. But imagining being caught sends another jolt straight to my hips.

Peeking down? A sliver of pale skin winks between the fabric.

If no one’s watching—

Sliding a fingertip under the edge, the soaked softness there wrings a full-body shudder.

"Aah… in, inside…"

Listening for footsteps, I move achingly slow. The swimsuit still tangled around my ankles means I can yank it back anytime—bending forward to hide myself, my breasts press against my knees. Stiffened nipples scrape the skin, and the mirror reflects the most shameless face I’ve ever made.

"Nnnh—! N-no… gonna m-moan…!"

Biting her lip, I grind the bunched-up fabric against her inner thighs—creating hot, deliberate friction over her most sensitive spots.

"Ah-! Th-this feels even… ngh! —coming… I’m c-coming!!"

My back arches on its own. No—someone might—! A frantic glance confirms the nearby stall’s empty…

"CUMMING—! NnngHAAH—!!♡♡"

Her fingers moved faster as heat spread through her entire body, making her knees tremble uncontrollably—

"Haah… haa…♡"

Her clit still throbbed relentlessly. The lingering warmth on her fingertips and the heady haze in her mind left her dizzy. Maybe it was the thrill of nearly being caught—her pulse pounded in her ears.

"…Shit, gotta fix this fast—"

She steadied her breathing, hastily pulling up the swimsuit bottoms from around her ankles. The cold material brushing against her hips sent another shiver through her oversensitive body. The top—? Ah, it had fallen to the floor. Just as she bent to grab it—

"Um…"

A voice from behind froze her in place.

Slowly turning, she saw the woman from earlier—the one who’d been blow-drying her hair nearby—staring with faint suspicion. Did I seem suspicious…?

"…Are you okay?" A slight frown creased her brow. "You look a little…"

Adjusting instantly, she forced an airy, too-high laugh and waved it off.

"N-No, I'm fine! Just… got a little overheated!"

"But you're drenched in sweat…"

That trailing gaze skimmed down—chest, thighs, knees. Fuck, still soaked from before! Moving fast, she swiped the towel over her skin, pretending to dress casually.

"T-Thanks! Really, I'm fine now!"

Flashing a quick smile, she busied herself with her locker. The woman’s tilted head lingered for just a second before she, too, turned away.

…That was close.

Legs still shaky, she slipped out of the changing room. The walk back—down the poolside, past the splashing water and distant laughter—felt torturously long. The breeze on her flushed skin set every nerve alight, and the fabric rubbing between her thighs with each step made focusing impossible.

"Dammit… I already came, so why's it still…?!"

Gulping, she swerved into the men’s restroom, slipped inside a stall, and—

—There sat her original body, slumped on the toilet, looking lazily dazed.

She grinned.

"Hah… Heh… Look at my dumb face—"

She stifles the sound with her palm, ears straining for footsteps—silence. Good. Sliding the swimmer's toned legs forward, she eases the stall door shut. The click of the lock echoes obscenely, sending another pulse of heat between her thighs. Crouching before her own slack, sleeping body, she grins at its vacant expression.

"…Heh. Cuter than I thought…"

Her fingertips graze the warm, oblivious face—smooth skin, pliant under her touch. Knees spreading wider, trembling hands tug the zipper down. The swimsuit snags against oversensitive skin with every shift, making her twitch.

"…Nh! Faster— wanna use this body to—"

Leaning in, sweat beads between her breasts. Through the parted fabric, his arousal presses insistently against her—

The tight stall fills with the mingled rhythm of two breathing bodies. A feminine hand—her hand, now—fumbles with his jeans.

"Fuck, grew even bigger since before—"

As golden hair spills over his shoulder, the barest brush of her tip against its length nearly buckles her borrowed knees.

"Sh-shit— still too sensitive—!"

One hand braces against the stall wall. The other curls around his shaft, the mismatch of skin—hers touching his—dizzying. A slow stroke from tip to base sends twin thrills: the weight of him in her palm, the pull inside her dripping core.

"Ungh—! Just— just wanna take it—!"

Hitching the bikini to one thigh, she notes the slick strands clinging there—and shudders. Hovering above him, she aligns her swollen entrance with his leaking tip.

"Ah—! Ah, g-going in—!"

A slow sink, and heat stretches her open—her inner muscles clamping like they were made for it. God, to be fucking myself in a goddamn bathroom stall—

"Hng! My cock's… stuffing me raw…! S-sorry, but feels too good, right…?"

Her golden hair, damp with sweat, clung to the back of her neck as she leaned in close to her original body—still slumped on the toilet seat—and deliberately teased in a lilting, filthy whisper. The thrill of uttering such vulgar words in this sweet, feminine voice was intoxicating.

With the bikini still hitched around one thigh, she lowered her hips slowly, feeling every inch of him sinking into her. The heat swallowed her whole—down to the base.

"Nnhaaah…! So this is a pussy…?! Holy fuck—it’s squeezing so tight…!"

Her senses doubled—the overwhelming duality of being both the spear and the sheath. She was fucking herself, filling herself, ravaging herself—pleasuring herself in ways she’d never imagined. Bracing one hand against the stall wall, she sank down completely, gasping as the tip kissed her deepest walls.

"Mmmngh—! S-shit… this is… fucking insane…!"

Inside, the pulsing heat throbbed—her borrowed body shuddering as every movement sent jolts through her oversensitive nerves. Her thighs quivered, barely supporting her own weight. Ahh… So this is what sex feels like…!

"Alright… time to move—!"

She lifted her hips slightly before slamming back down—squelch! The obscenely wet sound echoed in the cramped stall.

"Aahn~! W-wait… this body—! It’s clenching on its own… ngh!♡"

The moment she started thrusting, her stolen body broke. The thought—being fucked stupid by my own damn cock—sent tremors racing up her spine. The lewd sloshing of fluids filled the air as she began riding herself roughly.

"Haah… Hahh… Fuck… a woman’s body… is amazing…! This feeling—! I can’t *han— ngh!!"

Her fingers, pressed hard against the stall wall, turned white-knuckled. Meanwhile, her original body—still slumped on the seat—was subtly bucking upward. So he’s feeling it too, huh…? The sight made her stolen body burn even hotter.

"Nnaah~! H-harder’s fine, right…? I mean… it’s me…!"

Suppressing ragged moans, she ramped up the pace—her hips pistoning faster. The entire stall creaked under the force. Sweat dripped everywhere—mixing with friction-heated skin, panting breaths.

"S-sorry, me… Creampie’ing a random girl’s pussy makes me a scumbag, right…? Nngh… but… it’s my pussy, so… totally okay… right? Ahha~♡"

The bikini ties swayed between sweat-slicked breasts. The heat from her palms against the wall made the stall feel steamy, oppressive. In the deepest part of her—the tip of his cock pulsed, brushing tantalizingly against her cervix.

"Hah… Ahh— if you keep thrusting like that… f-for real… Ngh! You’ll knock me up… But… I wouldn’t mind… right? Ehehe…♡"

Every snap of her hips made her possessed body jerk, her womb clenching down with perverse purpose. The deeper heat—hotter, slicker—suckling greedily at the base of her own shaft. The sheer wrongness of it—forbidden, filthy, addictive.

"NnAAH—! Noo~! M-my womb’s… getting—ruined! Ahhn~! Filled with your… your cum…♡!"

Her original body—still unresponsive—jerked instinctively upward, muffled groans escaping. "Schlrp—glurch!" The obscene squelch of her tightened walls dragging against him made her thighs quiver, arousal slicked between them.

She was ruining herself—in the filthiest, most perfect way.

"Gonna cum…! F-fuck—look! My pussy’s like… begging for my baby…! See…? C-clenching like crazy… NNGH!!♡"

One hand slid down her stomach, tracing the bulge inside her—each twitch making her legs shake. Pressing just above her pubis, her cervix pulsed—her entire body going slack, knees buckling.

The power—owning someone’s womb like this…

"M’cumming…! I-I’ll… breed you… w-without even… ahha~ checking your cycle…! Fuck—just saying it makes… nghh~! My womb throb…!"

Her rhythmic pounding grew feral—the toilet seat rattling beneath them. Fear of being overheard only spiked the depravity. The pleasure inside her—the hammering, the bulging, the breedingpressure—was ready to explode.

"Aahh~! H-here it comes…! Gonna cum inside…! P-pump it deep—th-that stupid womb… take it… NNAAAGH!!♡♡"

The first shot struck her cervix.

(Would she conceive right here—right now?)

Her stolen body arched, a wild, wailing cry tumbling out as her system overloaded, cunt sucking his cum like a desperate, mindless doll.

"HYAAAAHH~! I-It’s in… inside meee~♡! Nngh…! Aahn…! You’re… twitching!"

Knees giving out, she collapsed against him—walls still squeezing, claiming, welcoming every last spurt.

(…But who was she really—between both bodies now?)

The stall had finally quieted, the only sound left was my own unsteady breathing. As I came down from the high, my gaze caught the "Thank you for using our facilities" sticker on the toilet paper dispenser.

"Ahaha… Guess this means… Thanks for letting me creampie your pussy…!"

Warm, thick liquid trailed down my thigh—I smirked to myself, flushed with satisfaction.

By now, the poolside had changed dramatically. The afternoon crowd had thinned, leaving only sparse visitors lounging on benches. Leaning back, I took a sip of the cold cider, mentally replaying today’s harvest.

"Hah… That swimmer girl, the stacked blonde… and… huh, two more, right?"

The drink went down smoother than usual—or maybe that was just the lingering memory of that bikini girl’s sensitive throat muscle working under my control.

Near the pool, lifeguards were murmuring in a frenzy. Something about "suspicious activity" near the lockers. Whoops. Probably a few ruined swimsuits and… other messes left behind in the stalls.

"Tch. Calling me suspicious… I’m just an enthusiast of women's locker rooms."

A snicker escaped me as I stood up.

On the way out, I eyed the line of girls leaving—the ones who’d been in barely-there swimwear earlier, now dressed modestly. "Pfft. What a waste of a good view…"

"Well, since the staff’s getting antsy… Guess I'll call it a day."

But summer was far from over. The automatic doors slid open—yellow-orange sunlight spilling over the pavement. I wondered idly if she'd gotten knocked up from our little… encounter. Or what color swimsuit to sample next.

"Hah. Maybe tomorrow’s lineup will be even better."

I took out my backup phone from my pocket, scrolling through the gallery of today’s experiences. Each thumbnail—a captured moment, a stolen thrill. My grin stretched.

"Damn… Summer really is the best ♡"
