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.

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.

similar to the ass ram or the butt fuck, it involves invading your partners asshole like a dipstick on a car's oil gauge
