Are you tired of those cheap battery operated toys? Tired of messing around with lousy vibrators. Are you ready for real sexual pleasure? Have you been searching for something that can satisfy a real man sexual urge? Well than it time for some power. Its time for real sucking and piston movement action. Its time to put away those cheap toys, and go to a real sex machine. Well now it�s finally here. DD Machinery, the makers of �Robospanker� presents, �Robosex�. Robosex is one of the first real sex machine made for man. Here�s how it works. Robosex uses a small electric gear motor which plugs into an outlet in your home. (No more messing around with batteries.) Position yourself underneath the machine lying on your back, so that your legs straddle the machine. Now adjust the height of the machine until you can insert your penis into the plastic cylinder which protrudes downward from the top of the machine. Next turn on the motor. The motor will than drive the plastic cylinder in an up and down motion. The machine should be started at the slowest speed. This slow stroking will arouse the penis and cause it to become hard. When the penis gets hard, a seal is created between the penis, and the cylinder. The piston motion will than create a vacuum, and suction inside the cylinder. Next turn up the speed of the motor, using the hand held speed control. The speed can be increase up to 160 rpm. The increase in speed will result in a pumping action. This vacuum and pumping action will ultimately result in an orgasm, like you have never experienced before. And like all DD Machinery products, it is designed and built to last. The height can be adjusted up or down to fit anyone. The plastic cylinder measures 1 1/2" in diameter, and 7" long. The cylinder can also be easily removed for cleaning, and storage. Like all of our products, your satisfaction is guaranteed, or we will refund your money in full. Built so solid, it comes with a full 5 year warranty!
