pervokink 

First found on FARK by a user, is a super duper mode of being horny, and doing some freaky things in the sack (or kitchen table, teeter totter etc)

Man, the pervokink I saw at the International Mr. Leather convention was out of this world! Who knew that a __________ could fit in someone's a$$?
