Mexican Paint Job
When two male painters, preferably Mexican in race, suck each other's penis while attempting to paint a house.
"I walked into a new construction home and two male Mexicans were giving each other a Mexican Paint job. They immediately ran when they were seen."
Mexican Paint Job
An accidental sex move caused by pulling out too late, due to pleasure, where you ejaculate inside of the vagina and outside on her pubic area creating a "cream on the inside and the outside" paint job.
Man, I was having the best sex of my life and didn't calculate the correct time to pull out giving her the good ol' Mexican Paint Job. Now I'm worried of having a lil kid.
