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.
