Sorry for all the stars above. If you want to see the uncensored version you can head over to Jockstrap Central.
Thier newly arrived Extreme Collection of jocks, jock briefs and thongs from Male Power all include rings, things, gizmos and gadgets for added fun and excitement. There's 6 designs in total, be sure to collect them all.
While there's too many designs to go into each one in detail here , let's just say that they all come with either strategically placed holes or include cockrings, sometimes one, sometimes two - all geared to get you excited and in the case of the cockring designs, keep you hard.
Although the included cockrings are a standard size, they're all attached using velcro so you can switch them out if you have a favorite cockring in your drawer or you find one that fits you better.
