Easy to adjust whatever your level of BDSM, another great bondage cosplay toy from the Gekikan ("stimulation") series is this pair of Nipple Vibrators. Coming in red or black designs, you can literally just slip the vibes onto her (or his) nipples and then sit back and enjoy the show. The wearer or the partner can then control the vibration with the connected controller, providing all kinds of fun variations on power games.
Safe and simple, her breasts will experience whole new areas of pleasure and stimulation, not to mention introducing lots of performance and bondage role-playing possibilities. Ideal for both novices and the experienced!
