"Butch fucked the mannikin through the hole he drilled in its crotch"

really? i'd say he fucked the mannikin _in_ the hole he drilled in its crotch. if he's very prudish, perhaps he'd fuck the mannikin in its hole _through_ a hole in a sheet he placed between them.

i believe if one fucks _through_ something, that thing is not the object being fucked, but merely some barrier between the fucker and the fuckee.
