Sona 2 Clit Stimulator 15 Sold
SenSonic: the softer silicone has been specifically engineered to absorb some of the sonic waves and transmit them back into your body, around the clitoris, for deeper but gentler sensation.
In other words, the silicone itself is engineered to respond to the waves and pulses to provide extra stimulation at the surface of the skin, as well as beyond.
