Master Series Ass Relax is a specialized desensitizing anal lubricant formulated to reduce discomfort during backdoor play. This water-based formula contains benzocaine, a mild topical anesthetic that temporarily numbs the anal area to help ease initial penetration and accommodate larger toys or partners. The 4.25-ounce (126ml) bottle provides ample product for extended sessions or multiple uses.

Key Features

• Benzocaine-based formula: Contains a clinically-proven desensitizing agent that provides targeted numbing action without completely eliminating sensation, allowing you to remain aware of your body while reducing sharp discomfort
• Water-based formulation: Safe for use with all condom types and toy materials including silicone, rubber, glass, and metal — cleans up easily with water and won't degrade your toys
• Medium viscosity: Strikes a balance between staying where you apply it and spreading smoothly — thick enough to cushion and protect delicate tissue without becoming sticky or tacky
• Generous 126ml volume: The substantial bottle size ensures you won't run out mid-session and provides enough product for gradual, patient anal play where reapplication may be necessary
• Part of the Master Series line: Developed by XR Brands specifically for adventurous anal exploration, BDSM scenarios, and size training

Compatibility & Use

This lubricant is latex-safe and compatible with all toy materials. The water-based formula won't stain fabrics and rinses away cleanly. Apply liberally to both the anal opening and the penetrating object, allowing 3-5 minutes for the desensitizing effect to take hold before proceeding. Reapply as needed throughout your session.

Important note: While desensitizing products can facilitate anal play, always proceed slowly and listen to your body. Pain is a protective signal — numbness should reduce discomfort, not mask potential injury.
