Queef

Here it is, a queef is the sound air that is trapped in the vagina makes coming out when a girl is tight and the penis is large for the vagina. Occurring often in the doggy-style or legs over shoulders position due to a large penis inside of a small tight vagina where the air is pushed into and out of the vagina during intercourse. Gentlemen, this is a verrryyy good thing. Generally it means that the woman has been trying to enhance mutual pleasure by contracting her vaginal muscles, and the in and out style of sex, especially deep hard thrusts after a just the tip phase, make this possible. If a woman can do this on command, then she has a tight control of her vaginal musculature and it is a very good thing. Enjoy gentlemen.

As he was penetrating her in the from behind position, her tight vagina queefed, letting him know that he had pounded her hard, and her tightness was worth the effort.
