The Sir Richard's Control Advanced is a stroker disguised as a shampoo bottle. Made from super soft Fanta Flesh, this stoker is ultra-realistic and designed to deliver the softest and slickest jerking sessions. The inconspicuous design of the shampoo bottle allows you to control the tightness and amount of suction. Once inside the Fanta Flesh sleeve, you can adjust the tightness by squeezing the bottle and create a super-tight vacuum for unbelievable suction action. It's waterproof, washable and perfect for the shower, bath, or hot tub
