Fun Factory is always thinking about bodies and shapes that will make them feel good. They have taken their popular Bootie Plug and added a cock ring! The ring has a 1.75" (4.5 cm) diameter that will fit almost everyone. Between the ring and plug, there is a raised portion that is there to rub against the perineum. The length of the plug is great for prostate stimulation as well! As you move, your motion will tug gently on the toy, sending waves of pleasure from the base of your penis to your prostate. They have thought of it all. Made of 100% silicone in Germany.
