its wen u put ur penis on the opposite side of the elbow, w/ the inner arm facing up. the one w/ the penis resting on his/her arm will then move the lower arm up and down, (like curling lifts for working out biceps), and the one hus penis is in the arm will mov back and forth
benal sex is great. no std's no prego chicks. its full proof and quite original.
