OK I've got more. This time all for masturbation
Batting practice
Dishonorable discharge
Doing some rapid one arm pullups
Firing your squirt gun
Fist-kebabing
Getting your palm red
Gunning the motor
Honing the bone
Ironing some wrinkles
Junior olympic pole vaulting
Knuckling your knob
Launching the hand shuttle
Mashing the monster
Milking your banana
Peeling the carrot
Playing hand hockey
Playing the pipe organ
Pud wrestling
Roughing up the suspect
Sending out the troops
Shifting gears
Shooting some seeds
Snake charming
Spear fishing
Throttle the bottle
Tossing the javelin
Tugging your tapioca tube
Tuning the antenna
White water wristing
Hail to the Queen!!
:hehehe:
