I worked at a little game room, and my girlfriend would come to "visit" me about an hour or so before closing. I would then throw everyone out, and shut off all the lights, and all the machines........well, almost all the machines. I'd leave on one air hockey table. We'd make-out for a while with her sitting on it, then I'd undress her, and myself, then put in a few quarters to turn it on, and climb right up there. Man, that was so hot! She would gush when she came, and it would make this cool gurgling sound from the air bubbling through. We must have done that a couple dozen times. She even brought one of her friends to see that table once. We tried other machines too, but the air hockey table became legendary.
