Only ugly women? Shouldn't a MILF be hot?
Well, initially, yes, but after rediscovering one's sexuality, most MILFs transform into MILTSPHCBOs (That's "Mom I'd Like To See Put Her Clothes Back On" if you couldn't tell).
I think you should expand on that and have some really suggestive imagery / animation flash on the screen before the player is transported to the MILF's house. Something that metaphorically represents what's happening to him... maybe a piston pumping or a monkey eating a banana, but with scary sound design and effects. Saw style, hahaha.
I think that might be a bit too blatant. The Path didn't do this, so it's still kinda sorta possibly open-ended about what happens to each girl after they meet the wolf, despite the fact that she's clearly had something very traumatizing happen to her with questionable levels of clothing still on. For a direct parody of that, I think a guy with a big grin and a sore butt is telling enough.
