“Please, fuck me master!” Marcy begs

Jo’s grip on Marcy’s pigtail tightened just enough to tilt her flushed face up toward his, forcing those wide, glassy eyes to meet his gaze while his other hand stayed busy between her thighs. Now he had two thick fingers buried deep in her soaked pussy, pumping in slow, deliberate curls that made her hips twitch and her breath hitch in little broken gasps.

“Listen to that, Marcy,” he murmured, voice low and mocking. “Your greedy little cunt is practically sucking my fingers back in every time I pull them out. Squish, squish… dripping down my wrist. You’re making a mess all over the alley floor, baby. You’re ****….”

Marcy’s made a shaky whine, her full heavy breasts straining against the too-small bikini top, nipples webbing the fabric. “Please… Master… don’t stop… I—I can’t take it… I need your cock… please…”

“Need it?” Jo chuckled darkly, twisting his wrist so the pads of his fingers dragged hard over that swollen, sensitive spot inside her. Her knees buckled further and he had to pin her tighter against the rough concrete wall to keep her upright. “You already got two fingers stretching that tight little hole. Most girls would be coming apart by now. But you? You’re just getting wetter. Greedier. Look at your pussy, it’s clenching like it’s got a mind of its own.”

He withdrew his fingers slowly, letting her feel every inch of the drag, until they slipped free. Marcy actually sobbed at the emptiness, hips bucking forward instinctively, chasing the fullness.

“Aw, poor baby,” Jo teased, smearing her slickness across her swollen clit in lazy, maddening circles. “Miss being stuffed already? Tell you what. Since you’re being such a pathetic, dripping little slut tonight, I’ll give you what you’re begging for… but...”

He pressed the thick, leaking head of his cock right against her entrance, parting her folds, coating himself in her heat, his head just inside her, then held perfectly still.

“You know,” he purred, rocking just the tip in tiny, torturous nudges. “I could slide in nice and slow, let you feel every inch stretching that hungry pussy until I’m buried to the balls. Then I could fuck you deep and steady until you’re screaming my name.” He chuckled and she made little noises of affirmation. That was exactly what she wanted and they both knew it.

He paused, fingers circling her aching clit while she whimpered and squirmed.

“Or…” His voice dropped lower, silkier. “I could make you wait. I tease your dripping cunt until you’re babbling nonsense. Until you’re promising me anything, everything I want. Until you admit out loud that this isn’t just a one-night swap anymore. That you’re addicted to being my soft, wet, big-titted fuckpet. That Mark’s gone, and all that’s left is Marcy, my needy little bimbo who lives to be filled.”

Marcy’s whole body shuddered violently. Her modified nerves were on fire; every tiny brush of his cockhead at her lips and his fingers against her clit sent lightning up her spine. She tried to speak, but it came out as a broken, “P-please… Master… I—I can’t think… just fuck me… I’ll do anything… I’m yours… Marcy’s yours…”

Jo’s laugh was pure, dark satisfaction. “That’s what I like to hear. No more pretending you’re still one of the guys. No more ‘just try it for a night.’ You’re hooked… hooked on how empty you feel without my cock inside you, how your nipples ache, how your pussy throbs every time I call you my slut.”

He leaned in, lips brushing her ear. “Beg one more time, Marcy. Beg Master to claim this dripping pussy. Beg like the ****, little whore you’ve become. Louder. Let the whole world hear what a cock-hungry girl you are now.”

Marcy’s voice cracked, high and wrecked. “Please… Master… please fuck Marcy’s pussy… stretch me open… fill me up… I need your cock so bad… I’m your slut… your fuckpet… please… please… don’t make me wait anymore… I’ll be good… I’ll cum for you… just use me…”

Jo grinned, a feral, victorious smile that was made crueler by the single neon ally light. Jo finally pushed forward in one long, slow, relentless thrust. He sank balls-deep into Marcy’s fluttering, soaking heat.

Marcy screamed in raw, girlish, ecstatic satisfaction as her walls stretched and reflexively clamped down like a vice around him. The stretch and fullness hit every hypersensitive nerve of her new pussy at once.

Her huge breasts bounced wildly as he yanked the bikini top down so her swollen nipples bounced with every brutal plunge. The sensation made tears stream down her mascara-streaked cheeks.

“Fuck… so tight… so wet…” Jo groaned, voice rough with raw pleasure. “Feel that, Marcy? That’s your greedy little cunt swallowing every inch of me. This is what you were made for now. No control. Just getting railed like the perfect little bimbo you’ve turned into.”

Marcy moaned in inarticulate response.

He set a punishing rhythm, deep, steady strokes that slapped wetly against her with every thrust, grinding his pelvis against her throbbing clit on every inward plunge. Marcy’s pigtails bounced wildly, completely undone.

“You’re mine,” he growled between thrusts. “This pussy? These tits? This needy little body? They answer to me now. Say it.”

“Y-yours… Marcy’s yours… fuck… fuck… Master… gonna cum… gonna cum all over your cock!”

“That’s it,” Jo snarled, slamming deeper, harder. “Cum for me, slut. Milk me with that tight cunt. Show Master how much you love being fucked like a girl.”

Marcy shattered, her first girlgasm ripping through her tiny curvy body like wildfire, pussy walls spasming, gushing slick hot juices down both their thighs as she screamed Jo’s name.

Jo didn’t stop. He gripped her broad ass tighter and guided her onto his cock harder and faster. He kept pounding through her climax, chasing his own first orgasm as a man, growling praise. “Fuck. You’re such a good girl. Squeeze me just like that. Yeah that’s it. I’m gonna fill your perfect tight little pussy up…” he promised as buried himself to the hilt one last time and came with a guttural groan, flooding her still pulsing womb in thick, hot spurts.

“Fuck… yes… fill up my dirty little pussy Master!” Marcy begged.

“Yes. Oh fuck yeah! This… is… ah… ahh… oh god… oh… oh… oh… yes!!!” Jo sagged as his cock spurted one final satisfying time.

Marcy whimpered through her own aftershocks, trembling, clinging to the wall, utterly spent and leaking his cum down her inner thighs.

For long moments they stayed locked together, the pair both sweaty, wrecked, breathing hard against the alley wall.

Jo finally eased out slowly, watching his cum drip from her swollen, well-fucked pussy with obvious possessive pride. He tucked a messy strand of hair behind her ear, voice softer now but still edged with ownership.

“This swap’s not over, Marcy. Not even close. You’ve got so much more ‘girl experience’ to earn and I’ve got a lot more plans for my favorite little fuckpet.”

Marcy, still shaking, still blissed-out and dripping, managed a dazed, submissive nod. “Yes… Master… whatever you want…”
