Duck-bill kiss

When a guy purses both lips out to look like a ducks bill to give a kiss to a woman after she's sucked his cock. This is done to insure that she doesn't try to sneak her tongue in there and get his own cum in his mouth.

Shaniqua came up to give Gerardo a kiss after he blew his wad in her mouth. He didn't want to taste jizz though so he gave her a quick duck-bill kiss and told her to go brush her stanky teeth.
