Get the Fifi mug.
A device, primarily used in jail, that is a towel wrapped tightly around a rubber glove with lube used for masturbating. The rubber glove can be attained from someone who has kitchen duty and the lube can be shampoo or another man's goo, whatever you have to use. You can hold it tight with your hand or use strands of the towel to tie firmly to your penis. Multiple gloves are used for the more endowed as it hurts really bad when you get caught up on one of those finger parts.
Jail people {not me} : Felon1 "Hey dude, you seem tense today you want me to blow you before outside rec? "

Felon2: "Naw, I made a Fifi during church time. I'm going to the law library later and I'm gonna fuck it under the desk to pretend I'm a big shot businessman who is getting blown secretly during a meeting."

Felon1: "OK dude, but let me know if you want me to suck your cock because I really like to smooth texture of the head in my throat."
