Male masturbator with grips by Perfect Fit This all new design uses our amazing SilaSkin to create what may be the Perfect Male Masturbator. This unique masturbator features our proven ribs and nubs design from our Fat Boy line, but with a larger opening and thicker wall construction to provide a wonderful feeling of tightness without needing to be squeezed with your hand. The innovative and simple hand-straps can be used in a number of ways and do provide that extra grip for ease of use. Easy Clean up: Wash thoroughly with mild soap and water.
