Well, it’s pretty embarrassing but here is what happened.
I was supposed to be alone at home and I took this opportunity to play with myself. It was sometime since I had sex, so I was really looking forward to enjoying it.
Though I was alone, I was careful. I was in my room and closed the door, although I didn’t lock it, I rarely do.
I put some headphones on and slowly got into the grove, removing my clothes one at a time. Eventually I took off my panties and was completely naked.
I was starting to really get into the grove, I remember moaning loudly while fingering myself and I didn’t notice the door open.
By the time I noticed my roommate’s boyfriend at the door watching, it was too late, I was climaxing, moaning and shaking violently while he was watching- peeping through the door.
I threw the pillow at the him the moment I was done. He apologized while backing out claiming he froze and couldn’t move seeing what he saw.
I was obviously pretty embarrassed. But the more I thought, the more I got suspicious. I eventually overcame the embarrassment and asked him why he came into the room. He claimed he doesn’t remember anymore after the ‘incident’
I have a theory. I think he heard me moan and purposefully walked in to see if he can catch some action.
