elephant disease and i'd say get the fuck outta here. knife to her stomach and i would never put my dick in her.
"okay sir, we found your semen in this poor girl's vagina, care to explain that?"
"we were dating"
"yeh, okay, right"
however, if she was dying from natural causes, i would be.. oh man this is a pickle. probably, so i vote yes. the old saying "pussy is pussy" applies here too
and if she dies and then you pull your dick out it's not like you didn't have your penis inside a dead girl if that's what some people are going for. if it was her dying wish, she'd have wanted you to finish i think

either way, it's not like anyone would ever request that on their death bed.
