This first timer goes to a whore house and the lady of the night asks him how he would like to do it. 69, doggie style, missionary, greek, etc.

etc. he doesn't know anything about sex, so he says " oh i guess 69." so they both get naked and start "69ing" each other, and the bitch leaves a fart.

the dumb guy whiffs it away and starts in on her again. a few minuets later, she cuts another fart. well, the guy throws the girl off of him, and asks him where he is going.

the dumb guy looks at her and says, "lady, i don't know about you, but i dont think i can take 67 more of them."
