My step sis was with me on vacation for the entire week and our parents were gone. I woke up next to her and she was barely wearing anything. I couldn t stop staring at her, I always fantasized about it but never actually was in this situation. She only had her panties on and a huge t shirt. I couldn t help but get hard and stroke my cock next to her. Its not like she was paying attention. I tapped it on her ass one time and I was throbbing. I did it again and again until she suddenly moved. It was awkward and I thought she was going to freak out. She slid her ass closer to me and rubbed it against my cock. I couldn t believe what was happening. She finally told me to rub my cock on her pussy. It accidentally slipped in a little bit. She liked it though and told me to keep going. Finally, I fucked my hot big tit step sis until I came all over her tits.
