magic happens

"Unstatua", Snape spoke as he raised his wand. Cho and Harry continued fucking under the influence of the magic pheromone coming from Harry's penis.

Unfortunately, Harry wasn't comfortable having anal sex with Cho, now that she had been turned into a boy. Harry wouldn't be able to remove his penis from Cho unless he came inside her, now his ass. Try as he might, Harry just couldn't bring himself to cum inside a boy's anus.

"It's no good", said Harry as he pumped Cho, "I can't cum into a guy. I just can't do it."

"It's OK Harry", Cho replied, "Just remember, I'm really a girl. Just keep thinking that. It's OK to cum into me, I really a girl."

Harry was still under the influence of the pheromone of Sirius. He was filled with a desire to cum into girls and turn them into sex slaves. That Snape had turned Cho into a boy was a clever idea to prevent Cho becoming a sex **** when Harry came into her, but it was not to Harry's liking.

"Something's happening", said Harry, "It's the phallic wand spell. I can feel it happening. The pheromone must be controlling my magical powers"

Although it wasn't often talked about, boy wizards could make spells without a wand under some circumstances using their penis as the wand. The phallic wand, as it was called often happened of its own accord when a wizard needed it most. Clearly the power of the pheromone was not going to allow Cho's transformation into a boy to stand.

Suddenly where Cho was, Snape, Ron and Hermione could see two people. One was Cho, the boy Snape had turned her into. The other was Cho as a girl.

"Oh No", said Ron. "Harry's penis is turning you back into a girl Cho. You've got to stay male until he cums or you'll become his sex ****"

Cho's voice was now both male and female together, "Ahhh, I'm turning into a girl. Oh Harry, stop it! You've got to cum into me while I'm still male."

Now Harry was clearly fucking two people, one male, one female. "I'm sorry Cho, I can't stop it. It must be the pheremone's influence. My penis is about to turn you into a girl!"

Snape, Ron and Hermione looked on as the battle raged in front of them. Cho trying to stay male, Harry trying to transform her. There was nothing more they could do,

"maybe if we switch Cho with a boy, that way his other wand will not work, and his cum will not do anything to a male" said Hermione, (how wrong she was)
