My recent ex and myself frequently talked about sexual desires during our time dating. A little while back she asked me to meet her at her school (as we are both in university) to study for a bit. This "studying" was not very productive as both of us couldn't keep our hands off each other. We found an empty classroom in one of the buildings, and as time went by we got to making out, and at one point she was straddling me at the front of the classroom. The thing with this was, it was right beside a busy hallway, and one of the windows wouldn't close. So we decided to see if we could find a more secluded classroom. We couldn't. They were all either locked, or had more windows. So we went back to the first one, and proceeded to get busy. We went to an area in the classroom which was a sort of alcove. She was wearing leggings, so she lowered them to the point where her pussy and ass were exposed. I undid my jeans, sat on a chair, and she got on me. We fucked so hard. I haven't seen her go this fast, or cum as hard as she did. At one point, probably 10 mins in she had to take a few minutes to catch her breath as I had made her cum harder than ever before. She got back on, and we both went at it. 20 mins later, I came inside the condom while she was riding me. It felt amazing. She got off, and I put the condom in a plastic bag. We both then went and got food to top it off. Best day ever.
