BIG O VIBRATING RING REUSABLE
The Big O is the mother of reusable vibrating mutual pleasure rings. Worn at the base of the penis and with the bullet at the top (closest to his belly), when switched on, the vibrating cycle progresses for nine stages over an eighty minute span. The soft gel plastic ring is super-comfortable and boner-compatible. (No worries, he'll be back up again in no time with this one.) It is wireless, waterproof, and has batteries included.
