I have been caught a few times. The most awkward was when a boyfriend's older brother barged into his bedroom while I was giving him oral. lol I couldn't face his brother for weeks.
The second most awkward would be when I had a male roommate walk into my room to ask me a question while I was getting it on with a mutual male friend. I eventually learned my lesson...lock doors and keep music low enough to hear if someone is outside in the hallway. lmao
