When you break your arm/wrist/or hand that you normally use to masturbate with, and have to use the opposite hand to masturbate, because the cast you have to wear, hurts your dick.

Watching porn via Google Chromecast.
I had the house to myself so I decided to do some serious casturbating and cast porn from my phone to my living room TV.
