Key Features & Fit Highlights
- Open Tip Architecture: The open-ended top allows for direct glans exposure, ensuring uninhibited natural sensation, intense tip friction, and seamless fluid release.
- Graemen Canine Knot Bulge: A bold knot section toward the base delivers an invigorating threshold stretch and a satisfying locked-in feeling during deep thrusts.
- Textured Exterior & Smooth Interior: Raised organic veins provide rich friction for your partner, while the ultra-smooth inner wall ensures frictionless comfort around your shaft.
- Integrated Ball Loop: A dedicated hole at the base comfortably secures your testicles, holding the sleeve firmly in place to prevent slipping or rolling off during play.
