Worn over a penis owning partner's shaft (or shaft and balls) or over the base of a favourite dildo, this 100% silicone cock ring provides some seriously effective erection enhancement benefits plus perfectly placed vibration. Position the vibrating section up top in the path of a mate's clitoris or perineum, or flip it around to target the wearer's balls. It's nice and stretchy for easy placement, but holds reliably tight to prevent slips and ensure a rock-hard erection (if that's what you're into!). The Round is graced with 10 steady, pulsating and escalating rhythms.
