Buttwank 

The act of sexually stimulating one's anal region by the use of a dildo. Also refers to anal sex, whether it's gay or not.

The guy from the pen was horny in the ass so he decided to give himself a buttwank by carving a dildo out of a bar of wet soap and beating his ass with it repeatedly.
