Casturbation

Casturbation relates to the art of masturbating whilst wearing a cast (caused from broken bones somewhere between the individuals wrists and shoulders).
It can often require a lot of patience and training depending on the size and location of the cast.

Dan: Must be hard for you, being single for the last 7 months and not even able to choke the chicken with that broken wrist?
Jeff: It was rough for the first month, but casturbation is really my only option
