Have you ever, by chance, felt like having a manta ray stroke your cock? Because if so, someone on the Sir Richard’s design team has great concept ideas. I'll never be able to watch a marine life documentary the same. The packaging shows you exactly what you are purchasing, a vibrating masturbation sleeve. There are multiple pictures taken with different perspectives to highlight each curve. The sleeve felt great. We used a water-based lube because of the silicone materials. There was only as much friction as we wanted there to be. A major perk is the fact that you can control the pressure at all times. We will be using this one again.
