Not quite as expected

Hannah arrived at the room of requirements and saw that there was already a room active. Suspecting that this was her mystery writer promising her the dick of a lifetime she entered the room and what she saw truly shocked her.

Harry Potter was there railing Daphne Greengrass from behind while Hermione Granger and Luna Lovegood we’re eating each other out. The strangest part was all the girls were wearing collars.

“Ah Hannah. You were able to join us.” Harry smirked.

“What the fuck is going on here Potter?! Why are these three wearing collars?!”

“Simple. They are my sex slaves. And don’t give me that look, they signed because they wanted to sign. But do you notice something here?”

Hannah looked around at the girls. Hermione, Luna and Daphne. Gryffindor, Ravenclaw and Slytherin.

“You have a **** for each house. And you want me for Huffelpuff.”

“Smart girl. You in?”

“What are you gonna do if I say no?”

“Wipe your memory and pretend this never happened. I don't want a girl who doesn't want to be here. Besides, do you want to miss out on this?”

As soon as he said that he pulled his dick out of Daphne, who then collapsed, and revealed the biggest dick Hannah had ever seen. The huffelpuff guys only went up to 5 inches and that was on a good day. Harry had them by at least 2 inches.

“What do I have to do?”

“Sign your freedom over to me and follow my rules”

This made Hannah think. Sign her life away and get the biggest dick of her life or walk away and have to go the rest of her life without ever having it and being stuck with the mediocre Huffelpuff dicks forever.
