The sexual act of
pummeling a lady's fanny with your knees. This act usually follows what is
termed "the full
kitkat". The fan-knee can be done with just the left knee, with the right knee, or for the adventurous couple - alternative knees, this can be a fantastic way to build leg muscles for the male, and achieves maximum "fankneeage" for the lady.
Sex with
Shelley is really
tiring, she's only happy if I give her a good
fann-knee.
