This collar can easily be the start of an intense scene.
Sure, comfy neoprene, velcro, and nylon collars don't win the most fashion points, but they can be part of some hard bondage. You can get a perfect fit around his neck, and the nylon is strong enough to take a lot of pull. The nipple clamps are a good start, but with the two other D-rings, you could hook it up to a hog-tie, an anal hook, or pretty much anything you can imagine.
