Step brother helping step sister with her sexy stretching

I knew it wasn't a good idea to let my stepbrother help me with my yoga stretching. He is too horny all the time and I was wearing shorts. I started to feel his boner through his pants and when I mentioned that I feel him hard he just started to play with my pussy. It was the point of no return. He started fingering my ass. He put to fingers in my asshole and told me he is about to help me stretch it too. I was in a pretzel position on the floor with my booty in the air and he put his dick in me, fucking me while I was screaming. He even made me go ass to mouth and suck his dick. He only fucked my ass and when he was done, he came on my face. I'm my stepbrother's anal whore now.
