German Slot Machine 

You take a naked girl, make her sit on something with her legs behind her head. You then take your life savings in coins and toss them into her spread open vagina.

Guy 1: Dude I totally gave Maxi a German Slot machine!

Chinese Slot Machine 

This is when a woman shoves ice cubes up a guys ass. The cold sensations will cause the guy to lose his erection completely. This technique can be especially useful to help control males that suffer from premature ejaculation.

Heather's boyfriend was acting really cocky and bragging too much about himself so she gave him the Chinese Slot Machine while they were having sex causing him to shrink down to nothing.

Portland Slot Machine 

Placing a number of coins, preferably quarters, in your male partner's anus, and vigorously jerking them off until the coins shoot out. This is called "hitting the Jackpot."

I gave my hubbie a Portland Slot Machine last night, and he's still crying.

Texas Chainsaw Slot Machine

You are just railing at a girl hardcore and then you decide to get crazy. You start off by loading a roll of quarters in the girls ass, then you put in some anal beads. Then you plant a foot on her ass. You rip them out and the quarters fly everywhere!

Dude, so me and my bros were in Vegas last weekend and we were just ripped! We found some hooker and she showed us the texas chainsaw slot machine! Let's just say we hit the jackpot!
