GRINDER PADS
Grinder pads (also known as grinding mats, lay-on vibrators, or ride-on pads) are a fast-growing category of adult toys designed to simulate the sensation of body-to-body friction or "dry humping."
Unlike traditional vibrators that require you to hold a small device against a single pinpointed spot, a grinder pad provides a broad, texturized surface area that allows you to use your own body movement and weight to dictate the pleasure.
