…Your beautiful brunette Step-Sister, Katy Faery, sits on the couch in lounge pants, and a tank top.. studying. Katy can't get out of her head what she witnessed at the party last week. She rubs her temples, and thinks back to when she walked in on you fucking another girl at the party. Her memory shows you having sex with Maria Jade at the party, and she saw all of it. "I don't want to think about it anymore... Why did I have to walk in on that?" Your step-sister thinks back to when she saw Maria suck your cock, and how you had no idea she was even there. "I can't think about this, I have to study." Katy's mind drifts off again to you fucking Maria from behind. "I don't want to think about her fucking him, I want to think about me fucking him." Your step-sister wishes that you were her boyfriend, and only fucked her and no-one else. Katy thinks about it, and decides that she is going to fuck you again.. she hopes that maybe you two will end up boyfriend and girlfriend. She puts her books down, and walks into your room... in just a robe. She jumps down on the bed, "Hey Step-Bro. There is something I wanted to talk to you about." Katy admits that she walked in on you and Maria fucking at the party. She thinks it was a little hot, but she doesn't like seeing you with other girls. Katy admits that she knows it's not fair, she told you that you two couldn't have sex, so it's not your fault for going to someone else to satisfy your hormonal urges. Your step-sister starts to strip off her pink robe, showing off her naked body. "I'm thinking, now, that I made a mistake." Katy starts to pull down your boxers, and tells you that she wants it to be just you two... She doesn't want to see you with any other girls. Your step-sister grabs your cock, "This is MY cock." Katy gets on her stomach, and starts to suck your cock slowly. Your step-sister licks and kisses up your shaft, and takes every inch of your cock down her throat. "I know you only had to go to her because I wouldn't give it up, I'm sorry." Katy kisses and sucks your cock...and then jumps on top. Your step-sister shoves your cock into her pussy, and starts to ride you. "Yes! I only want you to fuck ME!" Katy moans in pleasure as she bounces up and down on your cock. "Oh, Step-Brother! I want you to fuck me from behind... way better than you did Maria!" You get behind your sexy step-sister, and fuck her from behind. Katy backs her ass up onto your cock, and slaps her ass. She tells you that she is so happy you guys got to do this again. "Ok, Step-Bro...Get on top of me and finish." You climb on top of your step-sister, and thrust in and out of her tight little pussy. Katy's legs are lifted in the air as you fuck her harder, you grab her breasts, and your step-sister starts to play with her clit until you both cum together. Your cum drips out of your step-sister’s sweet pussy. "I only want you to fuck me, Step-Bro. So... Does this mean you can be my boyfriend? We don't have to tell anybody. It can be between just me and you."
