The cooldown day blurred into evening, the house settling into quiet routines after dinner. Richard helped clear the table, plates clinking softly, while Laura's eyes met his across the sink, a spark of shared secrets in her gaze. Elena lounged on the couch, scrolling her phone, occasionally glancing up with a sly smile that promised more explorations later. The air felt charged, like the hush before a storm, everyone attuned to the invisible clock ticking down.
Richard retreated to his room around ten, stripping down to boxers and sliding under the covers. The bed felt too empty without the borrowed weights and swells he'd grown accustomed to. He lay there, staring at the ceiling fan's lazy spin, mind replaying fragments—the slide of cock into tight heat, the gush of milk on skin, the quiver of muscles under his control. His hand drifted down, gripping the shaft, stroking firm as pre-cum beaded at the tip. But sleep pulled him under before release, dreams fragmented with shifting forms and urgent touches.
Morning light pierced the blinds, and Richard woke with a start, sheets tangled around his legs. For a moment, disorientation gripped him—his chest felt... different. He sat up, heart racing, and looked down. Gone was the flat plane of his torso; instead, full breasts rose with each breath, heavy and pert, nipples stiffening in the cool air. Panic flickered, then faded as the system's hum echoed in his mind: Swap initiated. Target: Sarah. Duration: Seven days.
Sarah. His college lab partner, the one with the athletic build from track, sharp wit, and a laugh that turned heads. They'd flirted in passing, shared late-night study sessions, but never crossed that line. Now, he was in her body, every inch of it. He swung his legs over the bed's edge—her dorm room, posters of runners on the walls, a track uniform draped over the chair. The thighs were toned, muscles coiling under smooth skin as he stood, a subtle strength humming through limbs. Between them, the pussy felt exposed, lips tucked neatly, a faint warmth already stirring from the morning's confusion.
He crossed to the full-length mirror on the closet door, shedding the tank top and shorts Sarah had slept in. The reflection stared back: mid-twenties, lithe yet curved—breasts C-cups, firm with youth, areolas pink and tight. Flat stomach leading to hips that flared just enough, ass rounded from squats, legs endless and sculpted. He turned, craning to see the cheeks clench, then faced front again, hands roaming. Fingers cupped the tits, thumbs flicking nipples that hardened instantly, sending jolts straight to the core. The clit peeked from its hood as arousal built, pussy lips parting slightly, slickness gathering.
A deep breath, and he probed lower, middle finger tracing the slit before dipping inside. The walls clenched around the intrusion, hot and velvety, so different from the gripping heat he'd wielded before. He added a second finger, pumping slow, thumb circling the nub until knees buckled. Moans escaped—higher pitched, breathy—and he rode the wave, juices dripping down the thigh as orgasm clenched the muscles in rhythmic pulses. Collapsing onto the bed, chest heaving, he licked the fingers clean, tasting the musky sweetness that was Sarah's.
Shower time. The dorm bathroom was communal, but early hour meant privacy. Water hit the skin like needles, beading on the breasts before trailing down. Soap lathered over every curve—sliding between ass cheeks, over the mound, fingers cleaning the folds thoroughly. He lingered, soaping the entrance again, the pressure building until he braced against the tile, frigging hard and fast. Climax hit sharper this time, thighs quaking, water mixing with the release that puddled at his feet.
Dressed in Sarah's clothes—sports bra hugging the chest, yoga pants clinging to legs and ass, a loose tee—he grabbed her backpack and headed to campus. The walk felt empowering, strides long and confident, the sway of hips natural. Classmates nodded hello, oblivious, and Richard—Sarah—smiled back, voice light as he chatted about the upcoming lecture. Inside, sensations overwhelmed: the rub of fabric on nipples, the breeze teasing the crotch, the subtle ache from earlier play.
Lab partner time: ironically, it was with his own body, now inhabited by Sarah's mind. They met in the biology wing, Richard's form looking awkward in its own skin, eyes wide as they locked gazes. 'Hey, Sarah,' his voice said from his mouth, a nervous edge. Richard nodded, suppressing a grin. 'Richard. Ready to dissect?' They worked side by side, hands brushing over scalpels and slides, tension crackling. Under the table, Sarah's foot—his old one—nudged the calf, a silent question.
Lunch in the quad followed, sandwiches unwrapped on a bench. Conversation started neutral—notes, assignments—but Sarah leaned in, whispering, 'This is insane. I woke up as you. Your... everything feels so heavy down there.' Richard chuckled softly, crossing legs to quell the throb. 'Tell me about it. Your body's a workout. Sensitive too.' Eyes met, heat rising. Sarah's hand—his hand—grazed the knee. 'Wanna compare notes later? My—your—room?'
Afternoon classes dragged, mind wandering to possibilities. Back at the dorm by four, Richard paced, anticipation knotting the stomach. A text buzzed: Coming over. Door unlocked. Minutes later, his body entered, Sarah piloting it with hesitant steps. Door clicked shut, and they stood facing each other, mirrors of swapped lives.
'You first,' Richard said, voice husky. Sarah stepped closer, hands lifting the tee to expose the flat chest, then shoving down the jeans. Cock sprang free, already half-hard, veins pulsing. Richard knelt, drawn by familiarity turned alien, mouth watering. Lips parted, tongue lapping the underside before engulfing the head, sucking with hollowed cheeks. Sarah groaned—his old groan—hips bucking as the shaft thickened on the tongue. Saliva dripped, coating the balls he cupped, rolling them gently.
Sarah pulled back, eyes dark. 'Your turn.' She—no, he—tugged at the yoga pants, peeling them down with the panties. Pussy bared, lips glistening from the day's buildup. Sarah dove in, face burying between thighs, tongue flat against the slit, lapping upward to flick the clit. Richard's hands fisted in hair—his hair—legs spreading as the mouth devoured, fingers parting folds to suckle the inner lips. The suction pulled moans free, hips grinding against the nose.
They tumbled to the bed, bodies entwining. Richard straddled the face, riding the tongue that plunged deep, walls fluttering around it. Sarah's cock throbbed untouched below, pre-cum smearing the thigh. Switch: Richard on all fours, ass up, as Sarah positioned behind, rubbing the tip along the wetness before pushing in. Inch by inch, the stretch burned sweet, filling the pussy completely. Thrusts started slow, building to slams that rocked the frame, balls slapping the clit.
'Fuck, it's tight,' Sarah gasped, hands gripping hips, pulling back to watch the shaft glisten with juices. Richard pushed back, meeting each drive, the angle hitting that spot inside until sparks flew. Orgasm crashed, pussy spasming, milking the cock that followed, hot jets painting the depths. They collapsed, cum leaking out as breaths synced.
Evening stretched lazy—shared pizza, stories of the day's oddities, fingers tracing new contours. Sarah sucked the nipples, drawing no milk but bites that pebbled the skin, while Richard jerked the cock back to life, edging it with twists and squeezes. Night fell with them spooned, Sarah's arm over the waist, cock nestling against the ass, a promise of more tomorrows in this borrowed form. The swap's web widened, desires intertwining across identities, day one sealing a bond as electric as it was forbidden.
