Think of it as an inverted knuckle duster, but made from silicone and not brass. The Rocks Off hand solo masturbator open sleeve means every cock size fits, apply a generous amount of lube to your cock and the sleeve then have some fun. 

I found switching the bullet on and off every once in a while whilst wanking gives you an intense build up. As I was about to cum I switched the bullet off completely and really felt the benefit of the sleeve’s contours. You can even remove the vibrating bullet from the sleeve to use on your balls or press on your gooch, while using the sleeve on your cock. This two for the price of one feature enables the toy to become not so solo :-) Fucking hot using this with or on a partner. Would recommend this to every guy out there.
