Fifteen minutes later as I was shooting a hot load of cum into her pussy to go with my previous deposit, she had her biggest orgasm of the evening.Fri...day at school, all I could think about was possibly screwing my mother. She was built very much like my aunts, with a little extra meat on her bones, although she was about two inches taller than the twins. Mom had heavy breasts and a big bottom, seemingly much like the twins, although I had never seen her naked so it wasn't really a fair. And we get to choose things, not just "do" the assignment. Oh, we get assignments, too, but so far none seems to be outright stupid. For example, we had to memorize a sonnet, and I picked one by Shakespeare. We were asked to recite what we'd memorized. But not the whole poem. When I was my turn, I said: It endsThy love is better than high birth to me, Richer than wealth, prouder than garments' cost, Of more delight than hawks or horses be;And having thee, of all men's pride I boast:Wretched in. As I light my wand, the obvious other occupant of the room lit theirs...and low and behold it reveals a Death Eater. Not just any Death Eater, but Bellatrix, Voldemort's apparent biggest fan girl.In perfect sync we exclaim"Bellatrix Lestrange!" Sweetheart!"We both stared at each other, me confusedly and her awkwardly. "I have some-" What did you call me?"She chuckles and beckons to me "you first." She flicks her wand and the orb is back filling the room with light, like a light blub off a. Just go to sleep," she mumbled.I smiled and crawled into bed next to her. it wasn't long before I was asleep. I can't remember what woke me up or how long I had been asleep but after a while, I opened my eyes and turned to my sister and got the surprise of a life time.She was lying next to me, on her back, completely naked. Three of her fingers were inside her vagina while her thumb was on her clit (though I didn't know that's what it was called when I was nine). Her other hand was rubbing her.
