Detroit Oil Change

The act of shitting in a girls mouth, then having her spit it back into your mouth.

"Man, last night, I gave Amber a Detroit Oil Change for the first time and that sick fuck loved every second of it."

Detroit oil change

When your side girl is a squirter and you bottle up her sweet pussy juice to take home as a bottle of lube to use on your wife on the same night.

My wife is running a little rough lately. I'm gonna try giving her a Detroit oil change tonight to keep her running smooth.
