As clear as ABC! This sex toy has two ends - both designed for penetration. They are cleverly though out to be used with a partner and are perfect for lesbian games.
Double ended dildos are various. Most of them are made from soft, pliable materials. That makes the toy to easily bend for simultaneous penetration. Some dildos are made from firmer materials that can't bend, like glass, for instance. They are perfect when it comes to sharing the sex toy during coitus.
Many double headed dildos feature ends of the same size. Others have an end thicker than other. The thinner end is designed for anal penetration.
