Lucy is a 23 year old beautiful trans sharing a flat with straight Mark. They get on well and are comfortable seeing each other naked in the bathroom. Although always straight, Mark sees Lucy as the hottest human being he’s ever laid eyes on. She is slim, perky natural small boobs, and is fully waxed all over with skin like porcelain to go with her long blonde hair. She is also uncut with an unusually long foreskin and an average sized cock. Mark is also uncut. One Friday night they’re drinking get drunk together on rosé and Mark starts asking Lucy about her intimate life. Lucy declares all her boyfriends found her ‘party trick’ sent them ‘over the edge…even straight guys she declares. “Do you think it would drive ME over the edge Luce’ asks Mark. ‘Wanna see and find out?” Asks Lucy. Marks heart skips a beat and he asks. What IS the party trick? Lucy calmly replies “I cum in my foreskin and keep it there and they suck it out like a walnut whip…always gets them off” Hesitant Marks stutters…”yeah I. I’d llllike to see that Luce. Luck lifts up her cotton skirt revealing pale blue panties then pulls them down revealing her beautiful smooth cock. mark gasps. “Come real close babe” says Lucy and Mark kneels right in front of her. She does not rush and slowly starts massaging herself. “ I’m cool if you want a taste hun” says Lucy. Mark almost faints. ‘But be gentle with me hun, just suck my foreskin softly” Mark obliges. He’s never been as aroused in his life. The taste is incredible and the soft foreskin feeling in his mouth is almost unworldly. ‘OK back up a little hun I’m gonna cum” whispers Lucy. It does not squirt and as the highly viscous cum oozes out Lucy bunches her foreskin at the top making a ‘cup’ Mark is mesmerised and shaking with excitement. “Ok babe start jerking yourself off and come and sip from the cup” says Lucy. Mark almost cums on the spot but holds off, bends down and dips his tongue in the cum filled foreskin. He is in heaven. ‘That’s it babe, now softly suck the nozzle’ she whispers. Mark obeys. The taste and scent are unimaginably hot. Marks cums a huge load as he softly swallows every drop of Lucy’s thick cum.

Chapter 2: Chapter 2

He was ready. The word echoed in the quiet room, a solid truth settling in his bones. Her weight on him was an anchor, not a burden.

Lucy stirred against his side, her fingers tracing idle patterns through the damp hair on his chest. She tilted her head back to look at him, her eyes gleaming with a mixture of affection and pure, unadulterated mischief.

“That was so hot, Mark,” she murmured, her voice a low thrum that vibrated through him. She shifted, propping her chin on his sternum, her gaze direct and challenging. “But I think I can get you hard again in minutes with my party trick. Then you can enjoy me.”

A laugh, rough and surprised, escaped him. “You’re insane.” The concept was ludicrous. He was spent, hollowed out, floating in a post-coital haze.

“I’m efficient.” She winked, then slid down his body with a predator’s grace, the sheets whispering against her skin.

He expected her mouth, her hands. He expected the same path as before. But she moved past that, her focus dropping lower, her intent clear. A jolt of nervous anticipation, entirely different from the first time, shot through him. This wasn't about his need; it was about her demonstration. Her art.

She knelt between his legs, her blonde hair cascading over her shoulders. She looked up at him, holding his gaze as her hands gently coaxed him. He was soft, oversensitive, his body insisting it was impossible. But he watched her, captivated by her concentration.

Then, she used her fingers in a way that was entirely new. It wasn't about stimulation, not exactly. It was dexterous, a subtle manipulation of his own foreskin, a rolling, pleating motion that was more like origami than sex. Her touch was clinical and intimate all at once, a precise application of knowledge. She wasn't just touching him; she was demonstrating a function he never knew he possessed.

He gasped, his back arching off the bed as a bolt of pure, electric sensation, utterly divorced from arousal, jolted through his system. It was strange, almost ticklish, but layered with a profound and shocking sensitivity. It was like she’d found a hidden switch, a secret circuit buried deep in his nerves.

“See?” she whispered, her breath cool against the heated skin. Her fingers didn't stop their delicate, intricate dance. “It’s all just… potential.”

And then, impossibly, the potential became kinetic. A slow, thickening warmth began to spread, a stubborn tide rising against all logic. His body, which moments ago had been completely sated, was now responding to her expert, unorthodox tuning. It wasn't the blunt force of want, but something more nuanced, a re-awakening driven by sheer, shocking technique.

He was hard. Fully, undeniably. The transformation under her ministrations felt like a magic trick, a biological sleight of hand that left him breathless.

Lucy smiled, a slow, victorious thing. She released him, leaning back on her heels to admire her work. “Told you.”

Mark could only stare, his mind reeling. He was exposed, vulnerable, and completely in awe of her. This wasn't just sex. This was an education.

“Now,” she said, her voice dropping to a husky promise as she moved over him, aligning her body with his. “Where were we?”

This time, when she lowered herself onto him, the world didn't just fade away. It shattered.
