A buddy of mine was in a hotel room and heard loud and fairly aggressive sex noises coming through the wall. He chuckled and turned the TV up a bit but couldn't ignore it when it started to sound more like it had become non-consensual. He phoned reception, who weren't interested, and the police, who turned up five minutes later and hammered on the door. Long story short, it turns out that acting out non-consensual sex fantasies was the couple's "thing" and he'd completely ruined their twice a year opportunity to get away from the kids and let rip on each other.
