When you ride a girl and you feel her enjoying, really close the orgasm, you give her a punch in the face or somewhere else. You let go your imagination.
Everytime Chuck Norris brings a girl back home from the club, he gives her a good monkey punch in the face when she's about to have an orgasm. Cause no one can have more fun than Chuck.
