Reminds me of when me and my buddy from high school used to have a running gag where we’d make whoever lost in Fifa stick his tongue up the other’s butt hole. We didn’t know much about the “cleaning up beforehand” aspect to it, so it honestly was the worst kind of punishment for the first few months. As time went on though we became numb to the experience and started making it a competition on who could stick their tongue up the farthest. We eventually had to stop though when his sister walked in on us. We made her swear she wouldnt tell anybody, because we already weren’t the coolest guys in school. Nobody else found out about it, and we haven’t brought it up since. There was nothing sexual about it, and we are both happily married now, but we had some weird experiences in high school for sure.
