Cheating SLUT caught on camera by housemate

On a very good night out, I returned home and brought back a guy that I had met. A cheeky kiss in the hallway turned into a bit more and although I thought that we were being very quiet, my housemate heard us.... and saw it too. We head upstairs to my room to continue our fun. I really hope that my housemate doesn't tell my boyfriend about this!
