Motor boaters

The medium- to large-sized breasts of a woman when clothed by a low cut garment that only extends superiorly as far as the widest point of her bust.

Can predispose the bearer to nipple slip.

"So I'm just trying to work, and in she walks with these motor boaters, all cooing and jiggling, and I about f*!cking lost my mind!"
