Intense missionary sex with a petite step-sister-in-law while her brother is away

I\'ve always had a thing for my stepbrother\'s girlfriend. When he was at work, I couldn\'t resist giving her a taste of my hard cock. After a wild lesbian session, I took her from behind, pounding her tight pussy and asshole. The messy scene was worth the risk, and now, we\'re looking into making it a regular thing.
