1) Joe was a
little chubby, and so was Molly his
girlfriend. Whenever they had sex the air caught between their sweaty bellies made a sex fart.
2) I was getting
great head from this girl when I had a sex fart, she didn't even care!
3) After Randy finished sodomizing Brian, Brian let out a sex fart that smelled like lubricant.
4) Kelly is a great lay, but I think she needs to lay off the broccoli or beans. She has sex farts all the time when we're going at it.
