I'm a slutty little step-sister and I'm having a girl’s night with my step-brother Jordan’s new girlfriend to get to know her better. I notice she is checking me out, and I ask if she likes girls, (she says no). To test that, I turn on “Bubble butt by Major Lazer” and give her a seductive dance with twerking. When I finish, she farts and apologizes. I just laugh, tell her "its ok", and I fart also. I start a farting competition with her, and if I win she becomes my girlfriend for the night. She’s unsure, but I persuade her. We both fart back and forth, and I can tell she is really loving my farts. I win and pull out a strap-on, and tell her I'm going to make her my bitch. I start fucking and dominating her with it. She tells me that I'm way better then Jordan. I start talking about how wimpy Jordan is. I tell her from now on she’s my girlfriend, not Jordan’s.
