Looking for weird manga

Anyone know this weird manga where the seme really likes the uke and would do anything for him but uke is scared of what his stepdad will do? So uke said, “I’ll let you do what you want after I died.”

Then one day stepdad “perhaps” raped the uke, and the uke killed the stepdad and begged seme to kill him. Seme was reluctant but couldn’t bear seeing the uke begging him miserably.

So seme killed uke and had sex with the uke’s dead body.
