The act of swaffling (smacking your penis against something) fast and furiously between a woman's breasts. Similar to motorboating but with a penile element.
You could motorboat your girlfriend, but may derive more pleasure from pontooning her instead. Just make sure it is ok to ejaculate in her cleavage before doing so.
