Morning light pierced the curtains, rousing Richard from a tangle of sheets soaked with dried sweat and cum stains. In Sarah's body, he felt the subtle ache in the hips from the night's prolonged riding, the pussy lips still sensitive, brushing against each other with every shift. The breasts heaved with a deep breath, nipples tightening in the cool air. Beside him, his original form snored softly, Sarah's essence keeping it relaxed, the cock limp and nestled in the crease of the groin.
He eased out of bed, muscles protesting the pull, and headed to the mirror. The reflection showed flushed cheeks, hair tousled wildly. Hands cupped the tits, squeezing gently to test the weight, thumbs flicking the peaks until they stiffened. Lower, fingers combed through the trimmed bush, parting the slit to reveal the inner pinkness, still glistening faintly from dreams of penetration. A quick rinse in the shower followed—water cascading over the curves, soaping the ass crack thoroughly, one digit probing the rear entrance experimentally, drawing a shiver up the spine.
Dressed in jeans that clung to the thighs and a loose blouse that draped over the chest, he prepared for the day. Sarah stirred as he packed the backpack, stretching his old arms overhead, the muscles rippling. 'Ready for round three?' she asked, voice husky from sleep, eyes roaming the form she once owned. Richard smirked, bending to nip at the earlobe. 'Only if you keep up. Group project meeting at noon.' Her hand slapped the ass playfully, fingers lingering to knead the cheek. 'I'll make sure you stay focused.'
Campus breakfast involved coffee and a bagel, chewed slowly while watching joggers pass, imagining the strain on their bodies mirroring his own building tension. In the humanities seminar, he took notes on poetry, but the words blurred as the seam of the jeans ground against the clit with crossed legs. Sarah, in the seat behind, doodled on his paper—crude sketches of intertwined limbs—her knee nudging the back of his chair rhythmically, syncing with his pulse.
The group project met in a study room, four classmates debating themes. Richard contributed ideas on identity fluidity, voice steady despite the heat pooling low from Sarah's foot, hidden under the table, tracing the arch of his sneaker before sliding up the calf. The touch was electric, calf muscles tensing, pussy responding with a fresh trickle of wetness. When the others stepped out for vending machines, Sarah leaned in, breath hot on the neck. 'Lift your hips.' He complied, and her hand unzipped the jeans stealthily, fingers delving into the panties to stroke the swollen folds. Two digits slipped inside, scissoring gently, thumb pressing the clit in firm circles. The build was swift, muffled whimpers escaping as the walls clamped down, orgasm pulsing quietly, juices coating her hand. She withdrew, licking the fingers clean with a wink before the group returned.
Afternoon brought a guest lecture on anatomy, ironic in their swapped states. Diagrams of nerves and erogenous zones flashed on screen, and Richard squirmed, the lecture hall's dim light hiding the way his hand pressed discreetly against the crotch for relief. Sarah texted under the desk: Bet you're throbbing. He replied: Your cock's probably leaking. Post-lecture, they wandered to the quad, finding a bench partially obscured by trees. Sarah pulled him onto her lap—his old lap—straddling the thighs, the bulge evident through denim. Grinding down subtly, the friction teased both, pussy lips parting around the hardness, clit catching on the ridge.
Hands roamed under shirts: his palming the flat chest, pinching nipples; hers kneading the breasts, rolling the tips until they ached. Kisses turned heated, teeth grazing the collarbone, but footsteps nearby forced separation, leaving them breathless and unsatisfied. 'Dorm. Now,' Sarah growled, dragging him back.
Once inside, clothes flew—blouse unbuttoned, jeans shoved down, revealing the soaked panties clinging to the mound. Sarah stripped his old body bare, cock springing free, veined and throbbing, pre-cum beading at the tip. He pushed her onto the bed, climbing atop to align the entrance with the head. Sinking down slowly, inch by inch, the stretch burned deliciously, walls molding to the shape. Once seated fully, he rolled hips in circles, grinding the clit against the pubic bone, hands braced on shoulders for leverage.
Sarah thrust up, meeting each descent with a slap of skin, the cock spearing deep, nudging the cervix. Breasts jiggled with the motion, sweat beading on the skin. 'Fuck, your pussy grips like a vice,' she panted, hands gripping the ass to spread cheeks, a thumb circling the puckered hole. The added pressure intensified everything, building the coil tighter. He rode faster, thighs burning, until the climax hit—pussy spasming, milking the shaft as waves crashed through.
Not done, Sarah flipped them, pinning the body beneath, legs hooked over shoulders for deeper access. Pounding relentlessly, the angle hit the sweet spot repeatedly, balls slapping the perineum. Fingers found the clit, rubbing furiously, drawing out cries as another orgasm ripped free, this one squirting lightly, wetting the sheets. Sarah chased her release, thrusts erratic, before burying deep and unloading—hot spurts flooding the core, excess leaking out with each pull-back.
They lay panting, but recovery was brief. In the bathroom, bent over the sink, Richard presented the ass, cheeks parted. Sarah's tongue delved first, rimming the tight ring, lapping wetly before fingers joined, one in the pussy, one easing into the ass, stretching both holes. The dual invasion made knees buckle, moans echoing off tiles. Then the cock replaced the fingers in the rear, lubed by spit and cum, pushing past the resistance inch by inch. The fullness was overwhelming, prostate equivalent sparking stars, as Sarah fucked the ass steadily, hand reaching around to finger the pussy in tandem.
Sensations overlapped—the drag in the back passage, the curl in the front—pushing to a shattering peak, body convulsing, pussy clenching the digits while the ass fluttered around the invading length. Sarah came again, pumping seed into the depths, pulling out to watch it drip down to mix with the front's arousal.
Evening wound down with pizza delivery, eaten cross-legged on the floor, bodies still humming. Fingers fed slices, sauce licked from lips, leading to lazy oral—Richard on his back, Sarah's mouth engulfing the cock, sucking with hollowed cheeks, tongue tracing veins until cum erupted down the throat. Reciprocation followed, face buried between thighs, tongue fucking the pussy while fingers twisted nipples, drawing a gush onto the chin.
As night fell, they curled together, the swap's third day etching deeper grooves of shared ecstasy, bodies attuned like instruments in harmony, the system's timer ticking toward more uncharted pleasures.
