The name speaks for itself: Trilogia is the greatest three-way vibrating penisring. The sleeve that holds the bullet has a flexible dotted tongue to tickle and stimulate the clitoris. The toy has 2 rings, the smallest one for the penis, the biggest and more flexible is a scrotum ring, both useful to keep a strongest erection. The powerful bullet is rechargable and removable, so you can also play it separately.
