Happy Ending Just Add Water Self-Lubriating Whack Pack – Sleeve
The Happy Ending Just Add Water Self-Lubriating Whack Pack – Sleeve brings a fresh take to solo pleasure with a self-lubriating sleeve that activates with plain water. No more scrambling for separate lubricant — this innovative masturbator is coated in a special material that becomes slick and smooth the moment moisture hits it. Its stretchy, ultra-soft body and reversible design let you customize texture and sensation, making every session uniquely satisfying.
Product Highlights
- Water-activated self-lubriating sleeve technology — just add water
- Ultra-soft, super-stretchy TPE material fits most sizes comfortably
- Reversible design with dual textures: ribbed interior and smooth exterior
- Frosted, semi-translucent finish for discreet, modern look
- Resealable storage pack keeps sleeve clean and travel-ready
How to Use
Rinse the sleeve lightly with water or moisten your hands. Slide the sleeve on and enjoy the instant slickness. The self-lubriating sleeve reactivates with each wetting, so a small spray bottle or sink proximity keeps the session going. For varied stimulation, simply flip the sleeve inside out to switch between a smooth glide and a massaging ribbed texture.
Cleaning and Care
After use, wash the sleeve with warm water and mild soap. Pat dry with a lint-free cloth and let air completely before storing in the included resealable pack. Avoid silicone-based lubes, which can degrade the material. This reusable masturbator is built for many encounters with proper maintenance.
