Is there such a thing?  I was with a lady for a massage (so no sex), but it was everything BUT FS.  As we were rolling around and I was massaging her tender parts, she let loose with about 5 minutes' worth of these sounds, intermittently.  Didn't sound like regular flatulence, but I could be mistaken.  On one of them, my hand was covering her kitty, and it felt like it was bubbling out from there....

Air is pumped in (intercourse/masturbation/whatever) - it comes out.  It might take some time - which is probably what happened.

We did not have intercourse, but I had been doing some things that probably pumped air in--not intentionally, but it could have happened that way....

"Pussy farts"

ut much funnier than queefing  

When air is pushed in , it must come back out . This can occur also with vigorous digits , toyplay , not just intercourse . I would be as red as heck if I was the lady ...

....it was no problem.  No foul smell, just the noises.  I was just curious, since it seemed almost certain that it came from the vag.  I had done some things with my hands that surely must have pushed the air in, so, as several have said, it had to come out at some point!  

But that hasn't stopped these guys from trying to figure it out:

Remember Google is your friend.

Those were the days my friend..

Cant make it up!

While doing that with with a civvie, because entering her felt best of all, I guess I pumped her up. She shut me out for a few minutes, then the air came out in loose-lipped bursts that embarassed her ineffably
