I'm in my room and overhear my step-sister talking to her friend about how she plans to lose her virginity to her boyfriend Randy tonight!! She's too sweet and innocent.. I can't let her get deflowered. I'm going to take matters into my own hands.. my plan is to take him into my room so we could have a private chat about something. Then I'll push him onto my bed and fuck all the cum out of him so that there's none left for her!!
