I could also have posted this in TIFU but it’s very NSFW so figured here was better.
I live in an apartment building in a city, on the third floor. Last night as I was climbing the stairs at about 1am, a little drunk, I heard what I thought was a moan as I got to the first floor. I stopped and sure enough I could hear this couple inside the apartment going at it like crazy. They had the TV on loud for obvious reasons but even in the hallway you could hear really clearly the sound of some really hot fucking. She was saying really dirty things and you could even hear the guys balls slapping her ass as he was banging her. By the way I only moved here a few months back so I have no idea who this couple is.
I was a but stunned but became very self conscious that I was standing in a fully lit hallway. I started up the stairs to my apartment.
