How long before Nishki cums and gives Pleasure his own vagina and assorted plumbing?
Once the vat is full...
Nishki smiled as she saw the vat filling up with Pleasure's first load of cum and kept up her pace, only slowing down to reach into her pocket to pull a syringe out, she wanted to bring Pleasure down to Earth a bit and had asked Dr Bluder if she could help her in that regard, the evil doctor had smiled and given Nishki the syringe, telling her that it contained a chemical that would permanently take a couple of inches off of Pleasure's cock as well as shrink his balls a little bit.
Nishki angled her cock in Pleasure's asshole and really ramped up her targeting of his prostate, making him go cross-eyed as he came again, filling the vat two-thirds full. While he was distracted, Nishki jabbed the needle into his right side and pushed the plunger. Pleasure whimpered as he felt the needle pierce his skin and he cried out as he felt the chemical flooding through his system.
"It won't be long now Pleasure, I can feel you getting ready to cum again and then, once you've filled up this vat, I'll give you the gift I just gave UltraHermBoy!"
Pleasure whimpered as the thought of Nishki giving him his own set of working female genitalia made him cum harder than his first two orgasms. Nishki looked on with barely disguised glee as the vat filled to the brim, turning off the vacuum pump, she waited until she was sure Pleasure had been completely drained before removing the pump from his slowly deflating cock, once that happened she ramped up her pace before giving one last deep thrust and roaring out her release. Pleasure wailed as he felt Nishki's cock get longer and thicker before her scalding hot seed splattered his bowels.
Not a minute later, Pleasure groaned in pain as his body was adjusted to fit his new female organs, he slumped in his restraints as exhaustion took hold. Nishki pulled out and transported the vat of Pleasure's super seed to her refrigerated van for delivery to Dr Bluder.
What happens next?
