Yes, once, my fucking degenerate neighbors. That night, the trauma was so great that I wasn't able to do anything, I just slept on other room.
Fortunately, I haven't heard them again, but a relative who lives in my house has (A woman), and it was great because she started making too much noise, like yelling and throwing things in the room to ruin those bastards moment. (The walls are extremely thin, so they definitely heard.)
That's what we incels must do. Whenever we have the possibility of ruining sexhavers moment, we should do everything possible to make them feel so uncomfortable that they cannot continue.
