Couple toys
"U" shaped couple vibrators are worn by women during penetration to have an extra stimulation of both clitoris and G Spot. Couple toys have not only different speeds and modes but also can be controlled by remote, for hands free play. A very recent and non-intrusive couple toy is the Eva by Dame Products model: it sticks to the clitoris, allowing easy penetration, hands-free play and intense external stimulation.
