Three weighted balls bounce and roll inside the BOUNCER’s shaft as you move it, giving you a deeper and more organic sensation than vibration. When you’re playing with this dildo with rumbling balls inside, slow and steady motion feels very different from hard and fast movement, and both are awesome. Use it on your own, hand it to your partner, or strap it on: its thin base let you get closer to your partner during harness play – making it the perfect strap-on dildo!
