Flap flicking

The act of flicking external labia during foreplay. When done correctly it will increase blood flow to the labia and clitoris, causing a more intense and pleasurable sensation.

Flap flicking is often requested during oral sex.

Trudi: Had the best sex with Greg last night; I love it when he gets things started with a good flap flicking. When I'm feeling like a naughty girl, I love asking him to flick my flaps.
