I was taking a shower while my gf at the time was staying over for the weekend. We had already had a very crazy weekend and had just fucked before I hopped in the shower. Once I got out and stepped into my room with just a towel, she was facedown on the bed, with her ass in the air rubbing herself like crazy. Instantly I became hard as she was moaning pretty loud. I dropped my towel and just watched for a while, stroking my cock and enjoying the show she was giving me. After a few minutes she begged me to come fuck her and she needed my cum again. Who was I to say no to that? I was more than happy to oblige and we fucked at least twice more before she had to go into work smelling like a cum dump.
