JOCK Vibrating Double Stroker

Customize your fit with this tightening masturbator! This stretchy, soft, TPE tunnel sits inside of a plastic case and can be adjusted to get smaller or larger for your shaft size and preference. Choose between 6 different tightness settings by turning the ring around the case to larger or smaller. Inside the tunnel are textured nubs that add to the sensation! Enjoy using it with the cap on one side or take it off for a cum-thru tip! Each side has a slightly different-sized hole, so you can choose which side you'd like to enter depending on how tight of a squeeze you want! Clean it up by rinsing it out and using mild soap and warm water, then letting it air-dry. Put both caps back on to keep dust and debris out. The case also provides a good grip so you can hold on easily as you stroke yourself with lots of lube! Only use water-based or silicone lubricants for best results.Take off both end caps, squeeze some lube inside and on your shaft, then slide your rod inside. Use the ring to adjust and tighten around your shaft. The squeeze adds pressure and feels so good as you stroke!
