Stroke 29 starts out thick. As you work it, the formula absorbs energy from friction and body heat, and transforms around the 29th stroke to a clear, ultra-slick fluid for a super-long glide. You feel the change as it happens and it takes you to a new level of pleasure. Vitamin E and Aloe Vera added to minimize irritation, soften skin and protect tissues. Stroke 29 is water-based, but is fortified with natural oils, and the same care should be taken as if using an oil-based lube.
