A flatulent-sounding explusion of
air from the vagina, caused by the pumping of
air into it with one's penis, or the spasming the vagina can go through during oral sex, "gulping" in and eventually expelling
air.
When
Stacey queefed while I was
making love to her orally, it startled the hell out of me, we both laughed, and I dove
right back in. I quickly learned that her queefs were her body's way of showing how much she loved what I was doing and I welcomed them.
