When a man is on a swing, gaining momentum, and the woman is on the ground in front of the man bent over. The man then swings down and taps her ass and then swings back, and then when he swings forward again, tapping her ass, and doing so over and over again.
Joe used the pendulum on me so hard on the playground yesterday.
when you pierce the skin between the vagina and the anus then put some string through it (a shoe lace). Then dangle a 3 pound weight from it and then swing the pendulum into the erect penis (chuckney channel) ta dah.
oh god my dick hurts from last night . my girl friend gave me the pendulum.
