First of all, yes, the dual entry can absolutely be used for double penetration play. The curvy, silky little bumps fit easily and pleasurably in the front and back. However! That's just the tip of the orgasm iceberg, so to speak. You can make good use of one or both of those super-soft ears to target the clitoris, nipples, penis heads, prostates, and more, or you can try tucking one inside and letting the other rumble and throb against your external sweet spots. Regardless of how you choose to play with the Dual Entry Vibe, you'll reap the benefits of nine super-powerful modes of steady, pulsing, and increasing vibrations that pulse through each stem. A button on the Dual Entry activates and varies the vibration, but you can also put control in a partner's hand thanks to an included wireless remote. Conveniently rechargeable via USB, You, Me, Us and the remote control are powered via the included charging cable and any free USB port or compatible adapter. Made from body-safe silicone, the flexible You, Me, Us vibrator is easy to clean with warm soapy water or a good toy care fluid/foam. This vibrator is compatible with any favorite water-based lubricant, but avoid contact with silicone lubricants and other silicone toys. Waterproof.
