The Birthday Suite

A fabled spa/resort somewhere in the USA where, on your birthday, you get to relax for the whole day. You don’t wear any clothes from the time you enter to the time you leave, and you get to spend all day having sex with multiple partners and feasting on Little Debbie snack cakes.

Where the hell is Tim?

Oh, he’s over at the Birthday Suite. He’s turning 41 today.
