Sunlight filtered through the dorm blinds, casting stripes across the rumpled sheets. Richard stirred in Sarah's body, the lithe form stretching with a languid arch that pulled at the toned muscles in her back and thighs. The previous night's exertions lingered—a faint soreness between the legs, the pussy still tender from the repeated thrusts and the final, grinding release. Beside him, his own body lay sprawled, Sarah's mind piloting it into deep sleep, chest rising steadily, the cock soft and tucked against the thigh.
He slipped from the bed quietly, feet padding to the bathroom. The mirror reflected the athletic frame once more: breasts bouncing slightly with each step, nipples grazing the air. He turned on the faucet, splashing water on the face, then let hands wander down, parting the thighs to inspect the folds. They were puffy, slick remnants drying on the inner lips. A finger traced the entrance, dipping in to feel the residual warmth, drawing a soft gasp as the walls fluttered. No time for more; classes awaited.
Back in the room, he dressed in fresh clothes from Sarah's drawer—running shorts that hugged the ass cheeks, a sports bra that compressed the tits firmly, and a tank top. Sarah woke as he laced up sneakers, rubbing eyes with his old hands. 'Morning already?' The voice was gruff, deeper than Sarah's usual lilt. Richard nodded, leaning down to press a kiss to the lips, tongue flicking briefly inside. 'Yeah. Lab at nine. Don't be late.' Sarah grinned, hand squeezing the thigh. 'Wouldn't miss feeling you up under the table.'
Breakfast was grabbed from the cafeteria—yogurt and fruit, the spoon sliding into the mouth with deliberate slowness, mimicking other insertions. On the walk to class, the campus buzzed with students, and Richard felt eyes on the body: the sway of hips drawing whistles, the legs striding with power. It empowered, the subtle flex of glutes under the shorts. In lecture hall, he sat near the front, notebook open, but mind drifted to the throb building from the seam rubbing the clit with each shift.
Lab arrived, the biology room sterile with trays of specimens. Sarah— in Richard's body—bumped shoulders as they set up, whispering, 'Your pussy's probably soaked by now.' Richard shot a glare, but heat flooded the core, confirming it. They dissected a frog together, scalpel slicing through tissue, but hands brushed constantly—fingers lingering on the table, a knee pressing thigh. Under the bench, Sarah's foot hooked the ankle, sliding up to nudge the calf, sending shivers up the spine.
Midway, the professor stepped out, leaving them alone. Sarah wasted no time, hand darting under the lab coat to cup the breast through the tank, thumb rolling the nipple until it peaked hard. Richard bit the lip, stifling a moan, pussy clenching emptily. 'Stop, we'll get caught,' he hissed, but legs parted slightly, inviting more. Sarah's other hand ventured lower, fingers pressing the shorts' crotch, rubbing circles over the fabric until dampness seeped through. The pressure on the clit built fast, hips rocking subtly, until a quiet climax rippled through, juices soaking the lining.
They finished the lab flushed, packing up with stolen glances. Lunch was in a secluded corner of the library stacks, bookshelves shielding them. Sarah pulled him into a narrow aisle, backing against the spines. Mouths crashed, tongues tangling wetly, hands roaming. Richard yanked down the zipper of his own jeans, freeing the cock that slapped against the stomach. He dropped to knees on the carpet, mouth opening wide to take it in, lips stretching around the girth. Sucking deep, throat relaxing to swallow more, tongue swirling the underside as saliva trailed down the shaft.
Sarah's hands guided the head, fucking the mouth with shallow thrusts, balls tightening against the chin. 'God, your throat's perfect,' she groaned low. Richard hummed around the length, vibrations pulling a shudder. Pre-cum coated the tongue, salty and thick. But voices echoed nearby—students approaching—so Sarah pulled out, cock glistening, and tucked it away. 'Later. My dorm after classes.'
Afternoon blurred: a track practice where Richard ran laps in Sarah's body, the ponytail whipping, sweat trickling between breasts and down the cleavage. Each stride jolted the pussy, friction from the shorts teasing relentlessly. He pushed harder, lungs burning, endorphins mixing with arousal until the finish line brought a heady rush, thighs quivering not just from effort.
By evening, back at the dorm, anticipation knotted the gut. Sarah waited inside, shirtless, cock already rigid against the thigh. Door locked, they stripped efficiently—tank top over head, shorts kicked off, revealing the sweat-dampened pussy. Sarah pushed him onto the desk, chair scraping, and spread the legs wide. Face lowered, tongue lashing the clit directly, sucking it between lips while fingers plunged into the hole, curling to stroke the front wall.
Richard gripped the desk edge, knuckles white, moans spilling free as the mouth worked relentlessly. Two fingers became three, stretching the walls, pumping with squelching sounds. The tongue flicked faster, nose grinding the mound, until the orgasm tore through, pussy gushing around the digits, thighs clamping the head. Sarah lapped it up, drinking the flood, then stood, aligning the cock with the dripping entrance.
One thrust buried it to the hilt, the fullness making stars burst behind eyelids. Sarah fucked hard, desk rattling, hands pinning wrists above the head. The cock dragged along every ridge inside, hitting deep with each slam, balls smacking the ass. Richard wrapped legs around the waist, heels digging into back, urging deeper. Sweat slicked their skin, breasts bouncing with the rhythm, nipples scraping the chest hair.
Switching positions, Richard bent over the desk, ass presented, cheeks spread by strong hands. The cock re-entered from behind, pounding the g-spot with precision, free hand reaching around to pinch the clit. Sensations layered— the burn of stretch, the slap of flesh, the twist on the nub—building to a second peak. Pussy convulsed, squeezing the shaft, and Sarah followed, grunting as cum erupted, filling the depths until it overflowed, trickling down the thighs.
They cleaned up with shared showers later, soapy hands exploring anew: fingers soaping the cock, lathering the folds, mutual masturbation under the spray until another round of releases left them spent. Dinner was takeout on the bed, bodies tangled, feeding each other bites between kisses. Night deepened with slow grinding—Richard atop, pussy sliding down the cock in lazy rolls, clits grinding indirectly through the base, prolonging the build until mutual climaxes washed over in waves.
As sleep claimed them, limbs entwined, the swap's intimacy deepened, bodies syncing in ways that blurred original boundaries. Day two wove them tighter, desires pulsing like a shared heartbeat, the system's whim holding them in this erotic limbo for days yet to unfold.
