Misty barges into my room the day of the party in her slutty outfit and catches me jerking off, embarrasing. She tells me that if I just got to the party I’ll get my dick sucked by one of her slutty friends. I still refuse and she advances on me while my dick is still out of my pants. I was in shock when she tried to touch it, telling me if I just give her a ride she will finish me off. Wow. A side of my sister I haven’t seen before. I am aprehensive but she bullies her way in and grabs my hard cock and starts stroking it. I guess it can’t be that bad if she just makes me cum and I take her, right? wrong. Right when I am about to cum she stops and tells me the girl at the party will have to finish me. What a BITCH. With my cock still hard I grab my stuff and take her to the pool party….
