Carissa walks in from karate and right away you are asking her how her class was. Carissa sits in her gi and white belt telling you what a badass karate girl she is as you beg to hear more. Your strong girlfriend can see you are getting turned on by her strength and power and demands you take out your cock and stroke it for her. Carissa humiliates you finding out your secret fetish fantasy and you love every second of it as you stroke. Wait until your karate girlfriend allows you and she will let you cum but don't blow before then or you might be the one to get the next beatdown.
