The transformation is instantaneous!

Paul whimpered as he felt the **** entering his system, once Bryce had completely emptied the contents of the syringe into his submissive partner, he threw the empty syringe into a sharps box for safekeeping and was amazed as Paul gave two moans as his new vagina (and all the plumbing) took shape. Bryce's mouth watered at the sight of Paul's glistening new pussy, what Doctor Bluder hadn't told him was that the **** permanently lubricated the 'victims' pussy.

"Well, Paul, it looks like you're ready for me to CUM aboard and give you a baby (or two or three!), are you ready to be fucked and bred?"

"Yes Master! Please knock up this willing ****!"

"After today, instead of calling me Master, I think I'll have you call me Daddy!"

Bryce stood behind a quivering Paul and rubbed his cockhead up and down Paul's soaking wet pussy before easing the head in, eventually making it to Paul's new hymen. Paul looked back at Bryce and nodded before bracing himself, Bryce took a good grip on Paul's hips before pushing through, instead of feeling pain from losing his hymen, Paul had converted it into pleasure and triggered another orgasm, spewing more ropes of his mind-controlling spunk into the vat.

Bryce smirked as he pushed the rest of his 10" cock into Paul's sopping wet gash, Paul moaning as he felt his hole being stretched to fit his new Daddy's cock, he let out another whimper when he felt his Daddy's rock hard abs smacking into his bubble butt, Bryce held that pose for a few seconds before whispering in Paul's ear.

"Daddy's home!"

Bryce then started fucking Paul, making Paul wail as his balls were being constantly hammered by Bryce's big balls, making Paul go cross-eyed. One particularly savage thrust had Paul making an Ahegao face, which he kept doing for the next two hours, Bryce finally taking pity on Paul when he noticed that the vat was full, pushing deeper than he had before, Bryce succeeded in penetrating Paul's cervix, holding his cock there before roaring out his release, flooding Paul's womb with rope after rope of hot, sticky, potent spunk, painting him white internally.
