The Soku Silicone Butt Plug Cock Ring is a combination of a prostate stimulator and cock ring. Both provide great stimulation. The butt plug is shaped to press against the prostate gland providing an intense feeling. The tapered tip makes insertion easy, and the cock ring stretches to allow it to fit around your penis. The cock ring traps blood in the penis, and this provides a stronger, harder erection. The combination of a harder erection and intense prostate stimulation makes this an excellent choice for some anal and cock play. The silicone material is a fantastic choice as it is both latex and phthalate-free, making it very easy to clean after use.
