As you are in the heat of sex, the man or woman sticks their head down into their partners anus. Upon reaching the anus, the one who is not face full of ass will then let out a fart into the others mouth. After the fart has been pushed out, the person will hold the fart in their mouth as they slowly go to kiss the opposite sex. She or he will then release the fart and blow it all over the face of their partner. This completes the wind tunnel.
Ms. Jansen really wanted to get freaky so I decided to give her a wind tunnel. She LOVED it.
