Mexican Jackhammer

Mexican Jackhammer
The act of a woman prividing a very rough hand job, like a jackhammer, whilst holding the balls up at the base of the penis in order to pound them with every down stroke. The mexican element is derived from the "Ay Ay Ay" sound the gentleman makes during the act.

My balls are the size of grapefruits this morning after Consuela gave me an amazing Mexican Jackhammer last night
