Well - you asked.
I'm into playing out a fantasy of being murdered by a gay or bi male who wants to mess around with me but cannot do it while I'm alive, because I'm straight. However after I am "dead", my body cannot say "no".
It can be undressed, positioned, washed, used as furniture, examined, groomed, made out with, or just left alone for 20 mins in an awkward position... hey, it's dead, it has no judgements. There's just one live person in the room - you.
Into fantasy of being shot, stabbed, maybe strangled, neck-snapped, maybe drowned. Found murdered. Perforated by many bullets, like from machine guns or firing squad. Post-mortem overkill. Optional self-soiling after death (if it does something for my partner).
You could try to force me to suck your dick at gunpoint, and I'd say "fuck no, get the fuck out of here", and then things escalate, you "kill" me, and eventually force my cooling body to give you a passive blowjob or passive handjob.
The sexual stuff actually does nothing for me on erotic level, but it enforces the idea of my boundaries being violated after I'm dead... and that idea arouses me. Well I'm fucked up, what can I say
