I ask my little stepsister to let me stay in her bed so I can take advantage and fuck her hard.

Since we were little we shared a room because in my stepparents' house there are not enough rooms, therefore I have to share a room with my stepsister, she always places the fan on her side, I ask her to let me in her bed In order to be okay, she agrees and while I warm her up to fuck her hard and come in her ass.
