Swapping Roles

Lisa's fingers traced the marker's contours where it lay on Edward's nightstand, her nightstand now, apparently. The morning light filtered through his blinds, striping their tangled legs in gold. Edward watched her, propped on one elbow, his free hand toying with a lock of her hair. She'd stayed over. Voluntarily.

"You're staring," she murmured without looking up, her thumb rubbing circles on the marker's cap.

"Thinking," Edward corrected. His fingers drifted to her hip, tracing the dip of her waist. "About possibilities."

Lisa finally turned, her grey eyes searching his. The marker clicked softly as she uncapped it. "Show me," she said, pressing it into his palm.

Edwards finger grabbed tightly around the marker. "Turn around, I will write it on your back."

Lisa grinned, before turning her back on Edward.

Edward wrote on her back: FUTANARI.

Lisa gasped as warmth pooled between her thighs. Her hips twitched as thick meat appeared just above her pussy, growing into an 6 inch long cock, a pair of palls, resting neatly between her pussy and the stem of her shaft.

Lisa's fingers brushed the unfamiliar flesh between her legs. Her cock twitched at the contact, precum beading at the tip. "Holy!" She scrambled onto her knees, her thighs trembling as the new weight swung heavily beneath her. Edward watched, transfixed, as she wrapped both hands around her shaft, her knuckles whitening. "Fuck, it's! it's mine," she gasped, her hips bucking into her own grip.

Edward's mouth went dry. He reached out, tracing a finger up the underside of her cock. “It’s beautiful.”, he said. “You have a proper girl cock now.”

Lisa tingled at the soft touch of Edwards hand. “Want me to suck it?”, Edward asked.

Edward's lips brushed the flushed head of her new cock. Her fingers tightened in his hair, her hips jerking involuntarily. "Yes," she whimpered. "God, yes."

Edward's tongue flicked out, catching the bead of precum gathering at her slit. The taste, salt and something indefinably Lisa, made his own cock twitch against his thigh. He wrapped a hand around the base of her shaft, marveling at the heat of her flesh, the way her pulse thrummed beneath his fingers. When he took her fully into his mouth, Lisa's moan cracked halfway through.

Her thighs trembled against his shoulders as he worked her, one hand straying lower to cup her balls, rolling the unfamiliar weight in his palm. Lisa's free hand scrabbled at the sheets, her back arching. "I'm gonna-!" Her warning dissolved into a cry as her cock jerked in Edward's mouth, her release flooding his tongue in thick pulses.

Edward swallowed greedily. When he finally pulled off, Lisa collapsed backward onto the mattress, her chest heaving. Her cock lay against her belly, still half-hard, glistening with spit and her own spend. "Fuck," she breathed, staring at the ceiling. "That was-!"

Edward kissed her before she could finish, letting her taste herself on his lips. Lisa moaned into his mouth, her hands drifting to his hips, her fingers brushing his erection. "Your turn," she murmured against his lips.

Edward turned around, offering his back for Lisa to write onto.

"Why not go full way?", she asked, as she wrote: FEMALE on Edwards back.

Edward gasped as his body began to shift beneath Lisa's fingertips. His shoulders narrowed, his hips flared outward, and a sudden warmth blossomed between his legs as his cock receded, replaced by a slick pussy. His hands flew to his chest where soft mounds swelled beneath his palms, nipples hardening against his fingers. "Jesus!" His voice came out higher, breathy.

Lisa grinned, running a hand down Edward's tits. "You're beautiful!", Lisa said.

"I need a mirror.", Edward said, scrambling off the bed, his unfamiliar breasts bouncing with each step. Lisa caught his wrist and tugged him toward the full-length mirror on the closet door. Edward froze at the reflection staring back: a woman with his eyes, but softer, curvier, her lips parted in shock.

Lisa pressed against Edward’s back, her chin hooking over his shoulder. Her cock nudged the cleft of his new ass. "Look at you," she murmured, palming one of Edward’s tits with possessive delight. "Perfect." Her free hand skimmed down his stomach, fingers slipping between his thighs. Edward gasped as Lisa’s fingertips found his clit, the sensation electric, alien. "Still want me to stop?" she breathed against his ear. "No.", Edward answered.

Lisa pulled out the marker once more. "Then let me continue your make-over."

Edward shuddered, as the marker once more was pressed against his back. Now smaller of frame.

Lisa carefully wrote: HUGE ASS, HUGE TITS, COCK SUCKING LIPS, SIZE QUEEN, ELASTIC PUSSY, SUBMISSIVE, LOVES CUM

After Lisa was finished writing, the changes began immeadietly. Edward cried out a feminine scream, as his ass ballooned out, growing to the size of medicine balls, jiggly and fat. His tits likewise grew into giant proportions, watermelons hanging heavy on his body. Edward trembled slightly at the new weights to his back and front, yet quickly gained the hang of it. Next his lips grew thick, outwards, as if made for the sole purpose of sucking, while his eyes resembled now nothing else but the desire to serve and be fucked by his new girlfriend.

Lisa stepped back, admiring her handiwork, her own cock twitching against her thigh.

"Fuck," Edward murmured, his voice a breathy soprano now.

Lisa put the pen against her own arm, quickly writing: MUSCULAR and STRONG, BIG TITS and writing 12 INCH COCK

While Edward was still mesmerized by his own changes, Lisa went again through her own transformation. Her muscles grew beneath her skin, toned and powerful, her tits inflated to the size of cantaloupes, and most noticeably, her cock surged outward, thickening and lengthening until it stood at a full foot long, resting heavily against her thigh. She flexed her biceps, grinning at her newfound strength. "Now," she purred, stepping forward, "let's put these upgrades to good use."

Edward barely had time to process before Lisa's hands gripped his plush hips, spinning him around to face the mirror again. His reflection showed a woman built for pleasure, his thick lips parted, his eyes glazed with anticipation. Lisa's cock pressed against his ass, the sheer size making him whimper. "Relax," she murmured, her breath hot against his neck as one hand reached around to toy with his swollen clit. "You wanted this, didn't you?"

Edward could only nod, his knees trembling as Lisa lined herself up, the broad head of her cock nudging against his slick entrance. The stretch was immediate, overwhelming, his body adjusting rapidly thanks to the marker’s modifications. A broken moan tore from his throat as Lisa bottomed out, her hips flush against his ass. "Fuck," she groaned, her fingers digging into his soft flesh. "You feel incredible."

Lisa didn’t wait for him to adjust, she pulled back and thrust in again, setting a brutal pace that had Edward’s tits bouncing wildly, his ass jiggling with every impact. His reflection was a mess of pleasure, flushed cheeks, drool slipping from his lips, eyes rolling back as Lisa’s cock pistoned into him. "You! ah! You take me so well," she praised. One hand fisted in his hair, tugging his head back to expose his throat as she fucked him deeper.

Edward’s thighs quivered, his pussy clenching around Lisa’s monstrous length as pleasure coiled tight in his gut. He came with a strangled cry, his body convulsing. Lisa didn’t slow, she kept driving into him, chasing her own release. When she finally stilled, buried to the hilt, her cock pulsed inside him, flooding him with warmth.
