This was a number of years ago but back in college my girlfriend and I were having sex in her dorm and literally right when we finished she got a surprised knock on the door. I panicked and just pulled my pants up (it was a between classes quickie kind of thing). The knock on the door was her brother who stopped by after one of his classes for some reason or another. So I ended up chatting with her brother for a little bit while still with wearing a cum filled condom tucked inside my pants.
