For a softer touch. This clever device is a clear silicone sleeve used to cover your plastic vibrators. It is super stretchy, handsomely designed with a stimulating ribbed surface and made out of a high grade silicone. One size will fit most medium sized vibrators.
There's a trick to putting them on: You roll up the sleeve until it's all the way up around the 1½" extension. Then place it against the head of the man's penis, or the tip of the vibrator, and roll it down snugly. There shouldn't be much worry about it sliding off. After just putting my finger in the sleeve, I wasn't able to pull it off until I rolled it back off the end.
