This bulldog penis ring is a combined penis/testicle ring with an attached screw-in bulldog. The combined rings securely hold the penis and testicles, effectively supporting the erection due to the phenomenon of blood circulation. The inserted screw-in bulldog with its specially designed sphere and 12 different vibrations and dual thumping functions can provide intense stimulation to the anus. It is covered with silicone, with a soft touch that feels great on the skin. It enhances the penis and offers pleasure to the anus at the same time! It can be recharged with the included USB cable.
