Similar to 'fisting' a girl, but the act is committed by someone who has a broken arm. The fister's arm is in a plaster cast.
Even though i've just broken my arm i'm still up for it tonight Mandy, infact i'm going to give you a good casting baby.

A sexual/BDSM fetish, whereupon an individual enjoys some part of the process of putting casts on people. Some people enjoy putting the casts on others, others enjoy having the casts put on themselves, and others enjoy seeing the finished product. Some cast fetishists get very creative about which body parts and in which positions the subject gets cast.
Becca is into casting and last week, she had the entire bottom half of her body done.
