Looking for a specific yaoi manga

I feel like I'm going crazy because I know this manga so well but I can't find it no matter what tag I use. It's a completed short (like around six chapters), occurs in high school where the uke has sex with a different male classmate most days in order to sleep at their house. One day he goes over to a new classmate who does not sleep with him (or he does I don't really remember I know at some point they sleep together), and he removes the jewelry for his piercings. Later it's revealed that the uke's brother abuses him by piercing his ears, and he stays exclusively with the seme. Please can someone find it I am struggling so much.
