"There's been a lot of device masturbation, if you will, and it needs to stop. I know your just updating your Facebook 15 times a minute, and there is no reason for it." My history professor.

An Electronic Masturbation Device, purchased at MEO, is a male jack-off machine that a guy uses or another guy can use to give his dick an awesome cumgasm. A dude's boner is lubed and inserted into it's oriface and placed over his cock-head and then turned on -- with 10 different settings, someone can use the cum-maker to give a guy's cock a mild to wild cumgasm as he blows hs load. Also used for "hands-free" or "forced" cumgasms.
My cadet roomie, Matt, bought an Electronic Masturbation Device, and he ties my hands behind my back and makes me suck his dick until we both have mind and cock-blowing cumgasms -- then he makes me swallow his cum and suck the device clean!

A girlfriend. When you're getting it on the regular, you don't need to hold your own. Now you can play videogames while bustin' a nut, because you've got both hands free.
Peter: "Dude, who was that hottie I saw you with at the club last night?"
Paul: "Oh, that's Bethany. She's my hands-free masturbation device."
Paul: "Oh, that's Bethany. She's my hands-free masturbation device."
