Similar to a queef wherein
air gets trapped in the vagina and is then released.
Fish-Lipping specifically occurs during intercourse and is considered to be the vagina begging for more. Like it is making a kissy
face/sound in an effort to lure the cock back inside.
There we were in room 303 having the
time of our lives. When I started pulling out for just a moment, her pussy started
fish-lipping for more. So of course we spent the rest of the
afternoon in there.
