Pontooning

When you motor-boat someones butt instead of their boobs.

Whadda ya say we finish this drinks and I go pontoon you for a while?
I am really looking forward to pontooning you after this steak dinner.

Pontooning

The act of motorboating a flat-chested woman with C-cup or smaller breasts.

I went to motorboat that bae but turned out she was wearing a padded bra, so when I got down in there, it was more like pontooning.
