The Soft & Wet Cup from M for Men is packed full of fun. The pocket masturbator is self-moistening. Simply add some water or spit and everything will be nice and wet, just like the original. Squeeze the cup and open or close the air valve for more suction power and pleasure. Masturbators from M for Men are soft, flexible and have sensational textures. However, the self-moistening properties do not last forever and are sufficient for about 12 times of fun. Clean with soap and water. Pat dry or allow to air dry before storing. Use only with water-based lubricant. It is recommended to start using water-based lubricants as soon as the self-moistening properties wear off. The cup is 18.4 cm long and 8.2 cm wide, much larger than other similar products on the market.
