Stackable Cock Ring Expansion — Sport Fucker Boner Expansion Pack Ice Blue by 665 Leather

Stackable Cock Ring Expansion User Guide & Play Styles

Building Your Four-Ring Stack for Couples Play

Combine this TPE cock ring add-on pack with your original Boner Kit for four stackable square donuts. Layer them in any order for graduated pressure both partners feel during play. Apply a water-based lube — see our lubricant guide — for smooth wear and clean removal. For more on what rings can do, read the benefits of cock rings guide. The body-safe TPE material washes easily after every session — rinse with warm water and mild soap to keep each ring clean.

Custom Color Combos for Confident Users

The ice blue finish pairs against darker Boner Kit shades for a split-color stack. Advanced users can mix two blue rings with two from another pack for a personal look. More rings mean more contact and a different pressure profile — experiment to find your preferred setup. Browse the Couples Pleasure collection for accessories that pair well with this expansion.
