In Europe there’s a student exchange program that let’s you visit another country and spend a semester there, attending courses at a department similar to yours. So I went to Berlin, Germany. My apartment walls were so thin that I could hear my female neighbor have sex with her bf. Most of the time it was really sensual so I’d be turned on but nothing crazy. The times they fucked roughly though, I’d always sit against our shared wall, completely naked and finger myself until I’d make myself cum, sometimes at the very same moment she would. It was insanely hot and I’ve never told anyone about it.
