.... since most queefs are created by tiny dicks, and/or cavernous (extensively used) vagina's I realize that the vast majority here only make love to sexual-aids and their hands... This question is more for those who DO have carnal experience with living women Blessings
it usually happens if you long dick her by coming out of the vag on the upstroke and then pushing air back in on the down, gives em a cramp if they don't blow it out.
