Spread her lips wide with this Spread ‘Em Poker Labia Clamp! The clamps are made of durable, nickel-free, stainless steel. Feel free to use any lubricant with them and to cleanse them with boiling water and cleaning solutions between uses without harming the device. At the top and bottom are two compression screws that you can twist to close the clamps against the labia and cause the vulva to be on display. Along each side of the clamps are rows of 4 pinch screws -also known as pressure screws- that poke into the tender tissue of the labia. Use the allen wrench included to adjust the pinch screws until they are in the right place. Make adjustments to the pinch screws before clamping down; if the labia arealready securely clamped the pinch screws will have enough pressure that each twist can potentially damage the tissue and nerves, so adjusting them beforehand keeps those nerves healthy so your bottom can enjoy the full extent of feeling every time you play! After taking a freshly cleaned clamp, take a wet towel, cloth, or wipe to her vulva as well to start fresh and clean on both ends. Put on some latex or nitrile gloves to add to the scene and give your fingers a little more grip as you gently rub her clitoris and stroke her labia. Once she’s warmed up, open the clamp and place it against her vulva; take a good look and see how her labia will fit into the clamps. Take the clamp and begin to open the sides by screwing the compression screws open, holding the round ball at the top and the bottom until they are evenly open. With the pinch screws all the way out so their base is flat and not pointing or poking in, begin to place one lip into the clamp and slowly compress the clamp on that lip and then the other. Start placing with her opening and tugging gently on the clamp to see if it stays in place. The spikes and screws help keep her from closing her legs so her vulva is on full display for you! After you’ve played a bit, remove the clamps by loosening the screws, then start to use the allen wrench for round two and turn the pinch screws so they poke into the space between the clamps. This time as you place the clamps on her labia, she will feel the poking, pinching, biting pressure from the pinch screws and the sensations will be enhanced tenfold! Measurements: Innermost opening is 3.75 inches in length, 1.1 inches in diameter. Each side of the clamp opens to 0.6 inches in width Materials: Stainless steel Color: Silver.
