I am really excited about this vacation with my stepbrother before he goes to college, and his girlfriend just dumped him so that’s even better. I want to make my brother feel good and I want his cock so I tell him I want to be his dirty little sister. We are only stepbrother and sister so why not let me stroke his hard dick and he agrees. He lay’s down and I quickly take his dick in my hand and pull my dress down. I am wet while he looks at my breasts and I know he can’t believe his sister is getting so wet and horny stroking his nice hard cock. I bend over in front of him and pull my dress up and he strokes himself while I bounce my ass in his face. I want to feel him cum so I grab onto his hard cock again and stroke it hard like a good sister and I cant help but cum myself while he moans. I feel his dick pulse and I know he’s ready to cum so I rub his dick faster and harder until his hot load blows all over me. I know that all he’s going to be thinking about while he’s at college now is his dirty little sister at home.
