Expanded into a huge she-cock

Stacy took a syringe with a clear liquid and injected it into Joan's small penis.

"Is that the silicone you used on her breasts?" Dr. Valentine asked as the penis grew in size.

"No, this a different one." Stacy replied and injected a second dose into the penis. "It lets the penis get longer and thicker, but let's it keep a natural feeling." She injected a third dose into Joans penis and made it grow to a size a little longer and thicker than it was fully erected before Dr. Valentine's treatment.

"That thing is huge." Dr. Valentine said nearly bursting into laughter thinking that just a few minutes ago she was happy about the penis getting smaller instead of bigger.

"And it'll always get that big whenever she gets aroused." Stacy said and a few seconds after she was done with injecting the liquid the huge cock became smaller and soft again, but it stayed size putting most men to shame. "I wonder if she would be happy about having such a huge cock again."

"And I wonder if she will use it to fuck some boy-cunts." Dr. Valentine added.

"I can make that more likely." Stacy went away and returned with another syring. She injected the content into Joan's testicles. "Now she produces cum whenever she has an erection. It'll make her feel like bursting until the cock get's jerked off, sucked or shoven into a tight hole. And then she will shoot a big load of cum."

Both women put on a wicked smile. Instead of turning Joan into a woman, they have let her stay a shemale and expanded her cock to the size of a male pornstar. On the form, which Joan filled out in Dr. Valentine's office, she had answered her sex with a s. It was a mistake from her, but now she was staying a shemale, though one with a huge cock.
