Trying to find a specific yaoi manga

I don't remember what it's called, but I do remember a specific sceme. The seme, who is normally the one initiating sex, hadn't been doing so for a while, so the uke became sexually frustrated. One night when they were in bed together, the uke got hard while the seme was alseep, and snook out to the bathroom to jerk off, but then the seme barged in and said something along the lines of, "If you jerk off, we're over" or "If you jerk off, I'll kill you" and then walked out.

Thank you in advance for your help
