Silicone and Plastic Chastity
The Plastic Chastity is a hard plastic that comes with 5 rings to help get a more perfect fit.
The Silicone Spiked Chastity is great for some extra play, with a little fun punishment for getting hard. The spikes are silicone so they won't cause any serious damage.
The Silicone 3 Ring has a great under piece to prevent slipping out from the chastity.
