Steve was in a bad accident, broke his right arm in 2 places. Good thing he's ambidicktrous because I wouldn't want to be around him if he couldn't jerk off for 3 months!
When you start your masturbation career (about age 9-14) as a male, but your dominant arm/hand has a cast on it (you may have broken it riding a skateboard) and you get bored so you make it work.
