It's been five times now I've watched my step dad fuck my mom, and he knows I'm watching them too. He tells my mom he likes to leave their bedroom door open as it gets too stuffy for him, so she lets him fuck her with the door half open. His cock is massive compared to my boyfriends and I find myself rubbing my pussy and clit as I watch them fuck. He's seen me playing with myself and it only seems to make him fuck my mom harder. Last week I watched her ride his cock anally and I was so turned on I made myself orgasm jst before my mom cried out from her own orgasm.
I'm niot sure if he'd ever want to fuck me, but if he did I'd have to decide if I was going to have him cheat on my mom. The thing is if he asked I don't think I could deny him and his huge cock my mouth, pussy and ass.
