Brushing Your Teeth 

A man puts tooth paste onto his penis, and then the woman brushes it around as if it was a toothbrush. Then after she is done brushing, she needs to floss, so the man pulls out one of his pubes and she flosses with that. Then after all of that, the woman needs some mouth-wash, so she jacks off the dude and washes her mouth with cum.

The dentist asked me, "Are you brushing your teeth a lot?" and I Said, "Yes" Even though the dentist said I needed a route canal.

Brushing Too Close To The Combine Harvester 

Doing or writing something that could enrage a large audience purely for you own sick pleasure, and the rush you get from this act.

Making a sexual comment about a guy on a girl's Facebook, whom you know that she is cheating on her boyfriend with. "You did that? You were brushing too close to the combine harvester man"
