the female puts either her right/left shoulder under the man's junk. Then they wrap their hand around the penis and basically "fist pump it like a champ".

Optional: you can start a dice roll on it and then work your way up to fist.
Penis pumping like a champ is like fist pumping on the Jersey Shore except in the sexual mode.
