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 Car Wash"
