Stepfather's unexpected advance on my girlfriend leads to a steamy encounter

I was hanging out with my girlfriend, just chilling and having a good time. But then, out of nowhere, her stepfather started coming on to her. I was taken aback, but I knew I had to do something about it. So, I confronted him and things got heated pretty quickly. But, to my surprise, my girlfriend wasn't too upset about it. In fact, she seemed to be enjoying it! She even started to strip down and get up close with him. It was pretty wild! The action got intense and hardcore as they went at it, with him thrusting hard and her moaning in pleasure. It was a sight to behold! The whole thing was pretty crazy, but definitely worth it. At the end of it all, he finished all over her big, juicy tits.
