That’s why I couldn’t find it. It was just a oneshot.
Thankyou
What I can only remember is that the seme (i think) is a player, always sleeping around, and the uke knew that. The uke even caught him sleeping with someone in their apartment. Then one time, the uke got fed up and decided to sleep around too. Uke brought his partner in their apartment, and were having sex I think in their room. The seme went home and heard them, he kept banging the door asking the uke to stop. Then the uke opened the door, looking poker face and told the seme how he felt like the when the seme have sex with someone else i think.
