A see-through mouth stroker that lets you watch every move and dial in the exact suction you enjoy. The clear canister, textured tunnel and twist-to-suction cap turn solo time into a slow, deep, ultra-satisfying experience—quietly and comfortably.
You want the closest thing to a sensual, wet “lip service” feel—without noise, chargers or learning curves. The MSTR B8 Lip Service delivers a realistic mouth entry, a clear view for visual excitement, and a case that creates adjustable suction with a simple twist. It’s an open-ended sleeve, so cleaning stays quick and stress-free.
Ready when you are: add a few drops of water-based lube and twist the cap to find your sweet spot. If you like a warmer feel, soak the sleeve in warm water first for a soft, lifelike welcome.
Gentle nudge: If you’re curious already, this is a great moment to add it to your basket—your future self will thank you.
Lips part, soft and slick. The first centimeter hugs you, then the inner ridges catch and release with every glide. Twist the cap a touch—air thins, pressure builds, and the tunnel narrows around you. Slow strokes become surprisingly intense. You stay in control the whole time.
