I guess my fiance banged it out with my Step-Sister In-Laws ex-boyfriend before I met her. It doesn't surprise me. My fiance is a sexy dirty slut. After all that's why I’m marrying her. But man, her step-sister is a super sexy even sluttier version of my wife. My wife is tall, blonde and curvy. Her step-sister is a dark haired, tiny little spinner more than a decade younger. I've always wondered if she was as much of a dirty girl as I thought. She's definitely a frequent visitor to my spank bank. Well, I got lucky. She finally made my fantasy come true purely out of spite and revenge. She said she wanted to see my cock before I marry with her step-sister because she fucked around with her boyfriend before. It’s only fair and we aren't actually married yet.
