Apologies for the obviousness of the following, but sharing some toe-curling, knee-trembling, heavy breathing pleasure with a partner always feels amazing. That super-close, ultra intimate togetherness is the whole point of sex, after all! If you've been looking for a way to share even more closeness, full-coverage firmness and some very good vibrations, this complete classic of a Vibrating Ring is definitely for you - and your partner! Simple, stretchy, and nothing-but-pleasurable, the beginner friendly design of this CalExotics offering slips snugly over the base of your or your penis-owning partner's shaft. During sex, it'll not only help that penis stay even firmer, but adds some subtle, buzzy vibration that you'll both be able to enjoy. Cue up vibration with a flick of a switch on the Ring's removable micro-vibe. 2 LR1130 batteries come pre-loaded, but you can easily replace them when they've run their course.
