What's next?

Six month swap contract…

Marcy watched her master pull out slowly, deliberately, letting Marcy feel every slick inch of him dragging free until just the head remained nestled against her fluttering entrance. Then he was out. She whimpered immediately, hips rocking back in helpless little jerks, chasing the fullness she’d just lost as his cock softened and cum dribbled down her inner thighs. She made to move and clean herself off.

“Not so fast, baby,” Jo murmured, voice thick with dark amusement. He still gripped her narrow waist, pressing her front to the rough concrete wall. “Stay there. Hands flat. Ass out. Legs spread. Show Master how badly this greedy little pussy still wants to be filled.”

Marcy obeyed without hesitation, her tiny palms slapping against the wall, back arching, presenting herself like an offering. Her enhanced breasts hung heavy and swayed beneath her, the too-small bikini top down around her ribs, leaving her swollen nipples swaying with every shaky breath. Her rounded ass cheeks clenched as she shifted her weight, thighs slick and trembling, pussy visibly clenching on nothing.

Jo stepped in close behind her, fingers sliding heavy along the cleft of her ass, not pushing in, just gliding teasingly up and down, painting her skin with their mixed arousal. He reached around with his other hand to toy with a dangling nipple, pinching, rolling, tugging, while his other hand firmly cupped her mound, fingers spreading her folds so the cool night air kissed her throbbing clit.

“Look at you,” he growled against her ear, sliding his fingers so they dragged back and forth over her entrance without breaching her. “Bent over in an alley like a **** little street slut. Pussy dripping, tits swinging, begging for cock without even saying the words. You’re not even pretending to fight it anymore, are you, Marcy?”

She shook her head frantically, pigtails whipping. “N-no… Master… please… just… just put it back in… I need it…”

Jo laughed, low, cruel, triumphant. “Oh, I will. Give me a few minutes to recover. But we’re doing this my way now.” He lined his fingers up again, pressing just the thumb inside, enough to stretch her open, enough to make her gasp and clench, but no deeper. Then he stopped toying with he breast and again held perfectly still.

Marcy whined, trying to push back on his fingers, but his strong hand clamped on her hips, immobilising her.

“Uh-uh. You stay right there. Feel how empty you are? How your cunt flutters like it’s starving? That’s going to be your life for the next six months if you want this cock again tonight.”

Her breath hitched. “S-six… months…?”

“Mmm-hmm.” Jo pushed his thumb forward another half-inch, agonisingly slow, then pulled back to tease her again. “The Swap Joint have a long-term, six-month swap contract. Fully binding. No early outs. No appeals. You sign it, right here, right now, and I’ll fuck you senseless. Doggy style. Hard and deep like you want it. I’ll fuck you until you can’t remember your old name. Until every time you cum it’s screaming ‘Master’ and ‘yes sir’ and ‘more please.’”

He thrust his thumb in another inch, then out again, shallow, teasing movements that made her sob with frustration.

“Or…” He leaned over her back, chest pressed to her shoulders, lips at her ear. “I stop completely. We walk back to the hotel. You spend the rest of the night aching, leaking, humping pillows like a bitch in heat while I site as a reminder of you what you could’ve had. Your choice, Marcy. Six months as my little fuckpet… or six hours of blue-balled misery… or is it blue ovaried.”

Marcy’s whole body shook. Tears of pure, overwhelmed need streaked her cheeks. “I… you can’t… please master… it’s too long… I’m not a girl… not a fuckpet… but… fuck… I need you inside me… please…”

Jo slid in another finger, grinding in slow, filthy circles. “Then beg for the contract. Tell Master you want to sign away the next six months of your life to stay in this slutty little body. Tell me you want to wake up every morning with tits bouncing, pussy wet, ready to serve. Tell me Mark’s gone forever and all that’s left is Marcy—my owned, obedient, cock-addicted bimbo.” He turned his finger slowly and her eyes closed and her breath was deep. “Just imagine. My cock… I’m getting hard again seeing you all small and horny and so… emasculated. My little big breasted girl…” he worked her pussy with his fingers. He knew exactly what she liked. Intimately.

She broke.

“Please… Master… I want it… I want the contract… six months… I’ll sign… I’ll be your fuckpet… your slut… just fuck me… please fuck me deep… I can’t stand it anymore…”

Jo’s grin was feral. He reached into his pocket and pulled out his phone. “Luke,” he said to his personal AI. “Amaned the Swap Joint contract.” The screen glowed faintly in the alley shadows, “to a six-month term.”

“Yes boss. Are you certain. Eighty percent of swaps over a month become permanent. After six months it’s nearly one hundred percent,” the AI observed.

“Yes Luke. I know. And so does Marcy…” Jo laughed.

“Wait, huh?” Marcy muttered as she struggled to follow the conversation.

“Thumb here,” Jo ordered, guiding her trembling right hand to the biometric pad of his phone, his other hand gently playing with her sex as his cock grew hard. “Read these words.” His ran the head of her cock up her cum slicked inner thigh and she sensed his imminent penetration.

Marcy’s voice cracked, high and wrecked. “I… Marcy… consent to the six-month body-swap extension… with Jo… fully binding… no reversal…” She pressed her thumb down. The phone chimed softly—green checkmark, contract sealed.

Jo did the same then tossed it aside onto a nearby crate. “Good girl.”

He gripped her hips hard enough to bruise and slammed home in one brutal, claiming thrust, burying himself balls-deep in her soaked, fluttering pussy.

Marcy screamed, a raw, ecstatic, ear shattering cry as her walls clamped like a vice at the sudden fullness. Her huge breasts slapped against the wall with every punishing stroke;. Jo reached around to pinch and tug her nipples in time with his thrusts, making her sob and buck.

“That’s it,” he growled, pounding her relentlessly, skin slapping wetly in the humid night. “Take it, Marcy. Take every inch like the owned little whore you just signed up to be. Six months of this—waking up stuffed, going to sleep leaking, cumming on command. You’re mine now. Say it.”

“Y-yours… Master… I’m yours… fuck… fuck… gonna cum… gonna cum so hard!

“Cum,” he snarled, slamming deep and grinding against her cervix. “Cum all over the cock you just signed away… probably forever.”

Marcy shattered, her commanded orgasm ripping through her like a storm, walls spasming, gushing juices down her thighs as she screamed into the night. Jo fucked her through it, harder and faster until his own release hit with a guttural groan. He buried himself to the hilt and flooded her, thick hot jism filling every inch of her spasming cunt.

They stayed locked together for a long moments, panting, trembling, dripping, until Jo finally eased out, watching his cum leak from her swollen, well-used pussy with a possessive satisfaction he would never tire of.

He leaned down, kissed the sweaty nape of her neck, and whispered against her skin.

“Six months starts now, Marcy. Let’s get you back to the suite… we’ve got a long night ahead, and I want to see how many times I can make my new fuckpet scream before sunrise.”

Marcy, her legs shaking, managed only a dazed, blissed-out whimper. “Yes… Master…”
