The Screaming O Vibrating Ring is the original award-winning vibrating sex toy for couples that enhances the ability for women to reach orgasm during intercourse! Approximately 75% of women need additional external clitoral stimulation to have a female orgasm, which is why we developed The Screaming O Vibrating Ring! This super-stretchy couples ring features a powerful mini motor that vibrates and stimulates the clitoris each time his body makes contact with hers. âPleasure knobsâ around the ring help distribute vibration around his penis while little ticklers on the motor help transfer vibration right where she needs it. The result is simultaneous stimulation that helps enhance the sexual experience for both partners!
