turn Cho into a man

"It's not going to be that easy", said Hermione. She crouched down and looked at Harry's and Cho's hips. "I'm afraid Harry's penis is frozen half inside you Cho. We're going to have to figure out how to get it out. If we unfreeze you both, Harry will just put his penis the rest of the way in and cum. Then we won't be able to get it out before Harry transforms you."

Hermione shuddered as her breasts shot up yet another size. "It doesn't help that I'm still turning into a sex ****. It's hard to concentrate when my boobs and butt keep getting larger and my mind keeps transforming!"

Snape had used the douche of Isis on the other girls rolling around on the floor. "That's all the douche we have. These girls will return to normal in a few hours. However, we won't have any temporic root to make any more with until next season. If Mister Potter cums into Cho she will become his sex ****. If she doesn't get any douche before the transformation is complete, she will be a sex **** for life."

"Hermione, Snape, you've got to help me!" Cho pleaded. "Please don't let me become a sex ****"

Harry felt his penis preparing to cum. It may have only been halfway into Cho and she wasn't moving, but Harry so close to cumming when Snape stopped them, he was going to cum anyway, "Hermione, you've got to get my penis out of Cho. I'm going to cum, I can feel it!"

"OK", said Hermione, "we need to think of a way to get Harry's penis out of Cho before he cums. We can't just pull him out as they are frozen together. If we unfreeze them, Harry will just put his penis in further. We need to defuse Harry's penis. I'll need a medical kit"

Hermione's boobs grew in another sudden spurt. "And we have to hurry. I'm still turning into a sex ****!"

Ron Weasley had gone to the school medical center and returned with a medical kit. He handed it to Hermione, "What are you going to do?" he asked.

"Well, let's see, what are the options?" Hermione mused.

"You could perform a vasectomy on him", Ron suggested.

"No, too complicated", Hermione replied. "Besides, I'm pretty certain that doing a vasectomy won't do anything about the cum in his prostate right now. It that cums into Cho, then she will become a sex **** in any case"

"How about cutting Harry's balls off?" said Ron.

"Fuck off!" exclaimed Harry. "What the hell sort of an idea is that?"

"No, no we could cut your balls off and reattach them later with the salve of Virgo", explained Ron.

"That might be an idea Ron", agreed Hermione. "However, I think it would be best to cut his penis off. Then we can separate Harry and Cho. Snape can unfreeze them and then we put Harry's penis back on with the salve. That would work"

"No way, you are not cutting off my balls, dick or whatever, OK. Think of something else!" Harry shouted.

"Oh shut up Harry", Hermione scolded. "You've fucked me and a whole lot of other girls. We are all turning into sex slaves, douche or not for at least six hours. Your precious cock can be reattached easily, so what the hell are you complaining about!"

Herminone raised the scalpel in readiness to cut Harry Potter's cock off.

"No need for that Miss Grainger. There is a simpler solution", Snape said. He pointed his wand at Cho and spoke, "Transgendra masculea".

Cho's frozen body began to change immediately. Her bottom shrank down losing it's female sexiness. Her breasts shrank away to nothing. Then her whole body changed shape becoming manly. Harry felt his penis moving as Cho's personal anatomy rearranged itself. His penis was no longer in Cho's vagina. She didn't have a vagina anymore. Harry's penis was now up Cho's anus. Cho's labial lips fused together to form a bag. Her ovaries dropped into the bag and transformed into testicles. Finally her clitoris grew longer and longer until she had a penis to match her new balls. Cho was now a young man.

"The pheromone of Siruis only affects females", explained Snape. "So Mister Potter all you have to do is cum into Cho's male anal passage and the spell should release you. Your cum will have no affect on Cho as she is now male."

"Oh God", said Harry. "I'm not a homo. I can't cum into a guy's arsehole"

"I'm still really a girl Harry", Cho reminded him. "Just imagine you're having anal sex with me. Which is in fact exactly what you're doing"

"Look Harry", said Hermione. "It's not really gay sex. Cho is a girl. Just cum into his, I mean her arse and we can separate you."

"Oh God, how did it come to this? I'm about to butt fuck a guy", moaned Harry.
