Enjoy a wonderful sensation with this penis plug. The plug is ribbed for a good stimulation during insertion and removal. It is made of flexible silicone, so it is soft to the touch and is comfortable to wear. The plug is hollow, so it allows urine and sperm to pass through. This way you can wear it as long as you want. Use the pull ring to remove the plug after use. It is easy to clean with a toy cleaner and a clean cloth.
