A personal trainer's intense workout turns into a steamy encounter

I was working out with my girlfriend, trying to get her to push herself harder. She's always been a bit lazy, but I wanted to help her get in shape. I was doing her the favor of lifting weights for her when she started to get a little too excited. I mean, she was getting way too turned on and I couldn't resist. I decided to take her right there on the couch, right after I finished stretching her out. It was a spontaneous thing, just like how we always like to do it. I had to make sure I didn't hurt her, so I was being really gentle at first. But as soon as she got into it, she was screaming my name and begging for more. It was a really hot and steamy encounter that left us both feeling good.
