they woke up in another place

When Harry woke up he notices that the three of them are not in his bed anymore. they were in another bedroom he didn't recognize. after a few minutes, he could only think that they were in the room of requirement.

Then a big group of naked girls appears from a door to the left with their eyes glazed. They were Lavander, the Patil twins, Luna, the Gryffindor's chasers, Susan, Dafne, and Tracy.

Before he could say anything Luna just his cock in her pussy and started moaning. the other girls just stay there waiting for their turn. Hermione and Ginny wake up and saw their master induction new slaves, so they went there to help him.

Hemione grabs her wand and says, "Cum Aeternum". With that, he felt different and his ball like they were going to explode.

"Master I make sure that you never run out of cum, and you need to cum at least ones every 12 hours."

As time passed Harry cum in every girl at least twice in each hole. When cums in the pussy of a girl for the first time, they change to be more sexy with a sex dole's body. Then declare their eternal loyalty to him.

Also in this time Harry became also addicted to fucking girls until they were his slaves, and was putting his eyes in a new target.
