Can’t recall the manga help

randomly remembered a scene from a series i read. pretty sure it’s a yaoi. also pretty sure it had the enemy to lovers trope. the scene is one of those bonus chapters that don’t really have anything to do with plot. The uke wakes up in the future and is confused. the seme, years older, walks in. he’s like rugged, very much older guy now. bangs him and comments something like “you feel tighter” LOL literally that scene is stuck in my head and i can’t get it out. then next day actual older “present” day version of uke comes back and thinks seme cheated in him because he didn’t have sex with him. idk if anyone knows what i’m talking about. Help please?
