IntoYou Ringo Vibrating Ring (Black)

A cock ring with a motor in it, driven from the ActiveJoy app, which means the person not wearing it can be the one changing the setting. That is the actual use of an app on a ring, and the reason it beats a button you cannot reach. The buttons on the ring work on their own if the phone stays away. As with every ring: twenty minutes at a time is the sensible limit, and it comes off the moment anything feels numb or cold.
