The risky jerk is a very dangerous, ballsy move. You must stand next to your parent's bed while they are sleeping, and masterbate. You must complete all the way till release. The riskyness is doing this next the head of your sleeping parents, they could wake at any moment.
DUDE! I tryed to do the risky jerk but my dad woke up half way through and cut it off!
