Is there a way to start sex with skeleton or rat？

I know animating is hard as balls, and that what I'm about to say should be infeasible without tons and tons of work involved, but it would be so cool to have skeleton animations that would make it so they're actually dry humping you, and your character's animations go like "wtf is this skeleton trying to do? did he actually retain memories from his sexual life, and is trying to hump me? must've been a perverted one...", and that particular animation doesn't actually count torwards your sex diary.
