The Masturbation Cream That Lasts Longer Than You Do. Stroke 29, Gun Oil’s premium cream lubricant, is designed to take masturbation to a whole new level. Unlike Silicone- and water-based lubricants, this thick, non-greasy formula provides more than just wet slipperiness. After years of research, our team has developed a lubricant that gets better the longer you use it. As the cream heats up from repetitive stroking of masturbation, around the 29th stroke, the product transforms from a thicker jelly to a thinner oil! With the combination of heat and friction, a guy might actually forget he’s using his own hand. Stroke 29 provides a glide unlike any other masturbation lubricant available. Stroke 29 skin-beneficial almond oil, Aloe Vera and Vitamin E and is fragrance- and irritant-free. Not recommended for use with latex condoms. Approximately 40 applications per tube.
