Seattle underground

the weird tunnels under Seattle that you’ve heard existed but really don’t want to spend money on a tour to see.

Yeah, I’ve heard Seattle underground is pretty cool, I’ve never been there though.

the underground railroad

when a girl starts sucking on your balls, then licks your gooch, and finishes it off with a rimjob. It's a funny experience that feels great, but is secretive just like the real underground railroad from back in the day.
