When a male is about about to bust in a girl's face, he pinches off his load and makes grunting noises like he's ready to cum in her face. She blinks her eyes like she's in a windgust, and then he blows it in her hair.

Having a chick fart in your mouth and immediately open-mouth kissing the fart into her mouth.

When she queefs at the same moment that you are hovering just outside the entrance and you blow a load right into the forthcoming gust, causing a spectacular blowback of cum droplets all over both parties.
