If you've already tried a number of onaholes and other masturbation toys, you might be on the lookout for something more adventurous. With its nubbed tunnel and combination of suction and vibration, the Vacuum Lock Vibrating Masturbator will give you all the right tingles. This powered masturbation sex machine might look complex, but it is easy to use. Just slide your member into it and adjust the size to hit the right spot. Depending on your preference, press the V (for vibration) or S (for suction) button for three seconds each to turn them on (and then off). Easily rotate between five vibration strengths and three patterns by pressing the buttons again. With the R button, you can then release yourself from its strong grip after you're done.
