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."
