Try playing Hitman Absolution with the invisibility and/or unlimited health/ammo trainer. There's plenty of bimbos to be slaughtered in the Strip Club level, and there's also those latex wearing assassin nuns if you're into that sort of thing ;)

There's a Skyrim mod named Namira's Goat on loverslab that allows you to slice off women's parts from their bodies and cook them. There's also a mod that introduces some sort of snuff club, but I forgot the name. If you have the time to go around loverslab, you'll find plenty of gems. Fallout 4 has a strip enemies with attacks mod, that works great with the latest CBBE dismemberable body and the Live Dismemberment mod that allows you to blast off legs and arms without killing the NPC.
