During the summer, my gf was teaching summer school classes and I would pick her up and drive her home. One day, while she should have been teaching, we started sexting about how hot it would be for me to bend her over her desk and take her from behind. Well later that day when I went to pick her up, she texted me and told me to come up to her classroom.
When I got to get classroom, she locked the door and we sat for a moment before we started to make out heavily. My lips on hers, and then sucking on her neck. Meanwhile one of my hands was wrapped around her waist and the other one was exploring the rest of her body. First starting with her breasts. Moving to the nipples. Stopping to give them a pinch and a tug. Moving lower to her stomach, and then finally rubbing her pussy through her pants.
I was so pent up from our sexting that I just had to have her. She could feel just how hard I was for her and so we dropped our pants, and I pushed her down onto her desk. Then I slid my cock inside of her and grabbed her by the waist. It was just like we had talked about, but so much better.
