My dad remarried and suddenly I got a super hot stepsister! One day, when she found out I was a virgin, she said, "Want me to do you?" and forced my pants off, but when she found out I had a big one, her attitude changed drastically! "Hide it fast! No, show it! I lied! It's not allowed!" she kept asking herself questions (apparently, a big one is a no-no because she might really fall for it). She promised not to let me in and started to tease me, but I couldn't hold back and easily inserted it! I even ended up cumming inside my wildly climaxing step-sister!
