Pennsylvania Dutch Shower Curtain

A sex act between at least one male and another partner. The male sneaks up behind a closed shower curtain while the other is in the active act of showering. The male then grabs the person in shower wrapping the shower curtain around there wet naked body. The penis is shoved against the curtain to insert into the person in the shower. The curtain acts as a semen barrier from this point on. This act should continue until climax or until the water starts turning cold.

Babe I'm too tired to do the Pennsylvania Dutch Shower Curtain. Can we do the Pennsylvania Dutch Breakfast instead?
