A "Wash and
Wax"
The person who wants to receive, lays down between the two providers
The first person urinates on the person laying between the two. They
will focus on one specific area. Say the face or chest.
After the first person finishes the wash, they
will make way for the second person, whos job is quite difficult, as they need to ejaculate on the exact same spot as the first person
pissed and on command. That's the
wax.
If there are more people in the wash and wax position, that's called a "Car Wash". Back in the fifties, it was called an "autowash"...but that term fell out of favor, except amongst the boomers.
"Hey, so if I understand tonight's festivities, it's you Steve and me. Steve is
really hot for a wash and
wax. If we can manage to convince John, Bob and Hector, I say we go ahead and surprise Steve with a
