ABSOLUTELY!! My fantasy is to fuck him from behind doggy style with a very sharp, long knife/short sword in his belly and as I begin to cum, push him forward onto the handle driving the blade the rest the way through him and into my belly. I don't know why but I always wanted to do that. Just such a damn HOT way to go!
I have a slight variation - to fuck another man doggy style, help him to his knees (rising up), stroke his cock with one hand - and slit his belly open - pubes to ribs with the other hand. Not cutting the intestines, but opening him up, so they would fall out of him.
To hold his guts in - wrapping him with a towel, and then tying him shut with a belt or rope - so he can fuck me, and gut me the same way.
Facing each other - we untie his wrap - and pull each other's guts out - fucking each other, as we slowly bleedout.
Careful removal of the guts - clamping and cauterizing the bleeders - one could live 5-15 minutes - GUTTED
