I catch my stepsister unawares with a sexual encounter in return for her promise not to disclose male visitors in our home

I walked in on my stepsister in the nude, and she didn\'t flinch. She knew my strict rules about no men in our apartment. I was surprised, and she offered me a wild night in exchange for keeping quiet. She\'s a hot, Latina MILF with a tight ass, and I couldn\'t resist. We had rough sex, and she let me fill her with my cum.
