The Kissa Sins Insatiable masturbator combines a realistic vaginal-style opening with a soft, skin-like sleeve and a textured interior. Its design is moulded directly from Kissa Sins and includes a smooth, tight entry for a close starting sensation. The sleeve sits inside a light-skin-toned case, providing a substantial handheld format with an overall length of 25.4 cm and a 1.3 cm canal diameter.

Inside, four chambers create a changing experience from one section to the next, combining spherical and conical shaping with varied bumps, nubs, grids and ribs. This intricate arrangement is designed for tight, varied stimulation rather than a uniform channel. Use with water-based lubricant, then wash the sleeve with warm water after use and allow it to air dry.
