I can not believe I was so dumb to leave my door unlocked, I got busted by my Step-sister Alice jerking off. I think I was in big trouble but it turns out Alice is a lot cooler than I thought, she wants to watch me jack my big dick, it must have really turned her on cause she asked if she could suck it. I gotta admit she is really hot and has the biggest tits, so of course, I let her suck me off but that was not enough, she wanted to fuck my big dick and then fill her up.
