Learn what your ideal size is with these Heavy Hitter Comfort plugs! The round ball serves as a large bulb for your backdoor to learn to pop inside. Test it out and see what your perfect size is! As you learn to take the big head inside of you, you can also learn to hold it there with the resistance from the solid, metal core! Enjoy the weighted center of the plug as it adds extra pressure inside you as you shift into different positions! Let gravity add to your pleasure as the plug pulls downward and train your ass muscles to hold it in place without letting it slip out. The plug is covered in silky soft premium silicone.
