Ready to level up what you bring to the bedroom? The Sport Fucker Boner Kit is a thoughtfully engineered two-piece system that combines a square cockring with an attached ball stretcher, plus a second loose ball stretcher — all in one package designed to maximize sensation and presence from the moment you put it on.

Material & Construction

Crafted from super-stretchable yet firm TPR, both square rings are flexible enough to accommodate a wide range of sizes while still holding everything securely in place. The dual-ring design works together to keep things snug and supported, and the added ball stretcher creates that extra tension that builds throughout wear. Because the kit is expandable, you can add 665 Leather’s compatible expansion packs over time to increase stretch and sensation even further — no need to replace what you already have.

How to Use

Start by slipping the square cockring with the attached ball stretcher into position, then add the loose ball stretcher for layered sensation. The adjustable, stretchable fit means getting it on is straightforward even for first-timers. For couples, the added visual enhancement and sustained sensation can translate directly into a more confident, satisfying experience for both partners. Once you’re comfortable with the base kit, experiment with expansion packs to customize intensity to your preference.

Care & Cleaning

TPR is non-porous and easy to maintain. Wash both rings with warm water and a toy-safe, mild soap before and after each use. Pat dry thoroughly and store in a cool, dry place away from direct sunlight. Avoid silicone-based lubricants; a water-based formula is the ideal pairing.
