A man goes into a brothel and tells the madam all he has ever done was missionary and he wants to try something different. The madam says I've got just the girl for you.
Go upstairs, second door on the right and tell Betty Lou your there for 69. He does this and when Betty Lou comes to the door he says he's here for 69 but he does not know what that is. She grabs him by the hand saying come on in your gonna love it. She explains to him that they'll get naked lay opposite each other and give each other oral sex. They do this with the girl on top. A few minutes into it Betty Lou farts in the guys face. He shrugs it off because he is enjoying himself. A few minutes later she does it again. This time he throws her off of him. She asks "What's wrong honey". He replies " I'm sorry but I don't think I can take 67 more of them.
