Ok wow

I have a good looking step dad I been wanting to hook up with also he has a foot fetish I once caught him sniffing my smelly flip flops. I'm hoping he makes a move I fantasize having his cock in my tight pussy

Are you her son or daughter? You didn't say. Either way, offer yourself to him. If he's younger than your mom, he's probably not getting enough sex from her anyway. You'd be helping their relationship. The old Raw Confessions website was full of posts from men having sex with their wives/girlfriends' kids. Many of them boys. When the two of you are alone sometime, offer him a blowjob. It could lead to a very satisfying relationship for both of you.

Im her daughter. You mentioning offering him head is so thrilling

Nothing wrong with that at all. When I was with my ex-girlfriend, her daughter told me pretty much the same thing the summer before she left for college and I confessed my feelings for her as well and it was the best sex of my life. We would go at it like rabbits every chance we got. Even after she went to college, every time she would come home during holiday vacations and some weekends here and there we would have sex together and it was amazing. I'm no longer with her mom but I still talk to her and we still hook up on occasion. Hopefully that never changes. All you have to do is tease him a little until you notice him checking you out and then tell him you've seen it and you liked what you seen, and take it from there. I'm sure all the pieces will fall together. Good luck!

I love the idea of this being me

Nothing is wrong with you, you’re just horny. Tell him what you need.
