When my mom called to let me know she'd be home late, I knew that was the perfect opportunity to surprise my stepdad. We've been hooking up for a while now. I've tasted his dick and felt it hard inside my pussy, but there's one thing we've never done: he has never cum inside me. I knew how much he wanted to do it because he kept begging me to let him, but I hadn't found the right moment until that day. I changed into the sluttiest outfit I could find, knowing he'd go crazy seeing my nipples through my shirt, and I touched myself, getting ready for him. When I went into his room, my stepdad wasn't there, but my stepbrother was. He only had to take one look at my g-string and the guilt on my face to know I've been having sex with my stepdad, and it only took him one second to use that so I would let him fuck me. I never thought I'd be getting on my stepbro's cock, but it felt so good. He pounded me in every position, and his dick was so fat and big that I was shaking. When it was his turn to cum, I was not ready to let him go yet. I still wanted him inside me, so he gave me my first creampie.
