We were hanging out back at a friend's place after a long night of nudey photo hunt and karaoke, and one female friend of ours showed us a special talent: She can queef (or vart if you prefer) on demand. She lied down on the floor, and you could hear her sucking the air into her hooha, and then expeling it immediately with a rather loud queef. She could do this at a rate of one a second for as long as she wants or until we got bored of it, which we didn't. One guy even stuck his head down there (she was fully clothed) and listened closely as she queefed directly into his face, and then he laughed like an idiot, which was making me laugh uncontrollably.
It's just the type of night I needed.
