With the Z Boners Stimulating Ball Bag, you will enjoy delightful stimulation of the penis and scrotum! Place the ring around the base of the penis when it is in a relaxed state; during an erection, the ring will fit snugly around the penis, reducing blood flow. Position the scrotum in the pulsing chamber and enjoy wonderful and unique stimulation. Thanks to the penis ring, you will experience a harder and longer-lasting erection, as well as intense sensations during ejaculation. The vibrator features 10 different speeds and patterns, as well as a waterproof silicone construction. After use, clean it with warm water and toy cleaner, and then easily recharge it with the included magnetic USB cable.
