hypersexual billy x touchy stu who doesn't let him hit but keeps turning him on for fun.

I think if Billy and Stu would become attracted to murdering and killing. I think that at some point, the pleasure they already got from it in the first place would have become sexual pleasure too. And with sexual pleasure through killing comes sexual pleasure by corpses. So my conclusion is that one of them (most likely Billy), would become a raging necrophiliac. He would probably not fuck the corpse by itself but have a threesome with it and Stu. Stu isn't attracted to the corpses, he sees them as his artworks, as something beautiful made by his hand. Although killing someone does sometimes get him hard, I don't think it would be majorly sexual pleasure for him. However, seeing his boyfriend become to riled up by his artworks gives him such a great amount of happiness and makes him feel so valued and wanted, that he would totally get hard from watching Billy desecrate their victims.

Honestly I want a scream modern au. I want one where stu googles how to best kill someone and billy goes "are you fucking stupid, the police can see your search history!" and Stu just goes "Duh, I'll just delete it.", completely unaware of how little that changes about the outcome and Billy just asks himself why Stu is his boyfriend and partner in crime.
