Train your beast with this simple and effective cock ring!
The Bolo easily cinches around your cock and balls in a variety of configurations. You can go with the old classic where you constrict blood flow out of your cock, creating a massive veiny hard-on. You can wrangle your balls into the game. You have so many choices and they're all so quick and easy to do.
Keep in mind that a little lube on your junk will help things slide more easily for the most comfortable fit.
