I've always loved fucking around with my step-sister, Addison. Everything was fine until my step-dad cockblocked me, he just burst right into the room on us! He was hiding in the closet and was watching me and Addison the whole time, she was just about to blow me. Now he demands we have sex right in front of him. I can not believe my step-dad just sits there as I pump away on my step-sister's tight pussy. Step-Dad tells her to open her mouth and demands I cum right in her mouth for her to swallow it. I can not believe how perverted our step-dad is, he is sicker than me!
