All girls want to be sex slaves

Herminone and the other girls lifted Harry up and put him in the biggest chair in the Griffindor common room. With such huge balls it would be difficult for Harry to stand.

"Now girls", Hermione ordered, "In a few hours all of you will transform back into ordinary girls unless you sit on Harry's lap and take more of his cum. Who wants to be totally transformed into Harry's sex ****?!"

All the girls raised their hands in a chorus of agreement. Then the girls each took a turn to sit on Harry's lap, his penis going into their vaginas to give then the second does of pheromone laden cum that would ensure they would stay sex slaves. With the massive testicles Harry now had he couldn't help himself. He filled each girl with a huge dose of his cum making them his sex slaves for life.

One after another, girl after girl sat in Harry's lap. His penis would enter their vaginas and with his now massive testicles, Harry would pump huge amounts of pheromone laden cum into them. These girls had already been turned into sex slaves by the magic of the pheromone in his cum, but were compelled to want more and more of its magical transforming power.

As the girls took in more of the cum, the signs of their transformation increased. Breasts grew larger, hips wider and each girl was filled with an ever greater desire to serve their sex **** master, Harry Potter.

Thanks to the fact the Hermione had magically made Harry's balls grow huge, the pheromone was now more powerful than ever. Harry hadn't wanted to transform girls at first, but now, even he had fallen under its influence. He now wanted to make more and more girls into his sex slaves.

Several of the transformed girls had been prowling Hogwarts for any more untransformed girls to bring to their master.
