Yeah I can! *Shoves his hand down the back of her pants (boy)

Get the Check my oilmug. I was finger banging Sarah and decided to oil check her to see if she would be into anal but she was full oil so I didn't go for it.

Get the Checking her oilmug. An act whereby an individual inserts his finger or penis into the asshole of another. Much like an oil check on a car, the appendage can then be examined to determine whether or not the contents are clean or dirty.

Get the oil checkmug. The act of shoving your finger into someone's asshole and checking how far up your finger the shit marks go, similar to a dip-stick in a car.
