Motorbutting

When you draw nipples on her asscheeks and motorboat her ass.

"I'm so motorbutting you tonight."
"What the fuck is that? Is it another one of those weird Urban Dictionary sex things?"

motorbutting

The act of perform a motorboat, but on someone's anus.

We were about to start some rusty trombone, but it wasn't hard, so I turned to doing some motorbutting.

Motorbutting

To motorboat a girls ass. Just like the titts except you do it with the butt cheeks

My girlfriend was annoyed by me motorbutting her every time she bent over
