Doing double duty,  Fantasy For Her Roto Suck-Her combines vibration with suction directed straight to the clitoris. The Suck-Her’s head swivels into perfect placement no matter what position you (or you and a playmate) might have gotten into. Circling the majority of the vulva and clitoral area, the soft silicone surrounds sweet spots while vibration pulses or suction sucks. Hit (S) to activate gentle suction and (V) to experiment with seven modes of throbbing vibration. Release (R) will dissolve the suction instantly. In ultra hygienic and hypoallergenic Elite Silicone, the Suck-Her sanitizes easily and thoroughly. Wash well before and after use using warm soapy water or a favorite toy care fluid/foam. Be sure to choose a good quality water-based formula . Requires 2 AAA batteries (sold separately).
