The Black Tenga Flex is a unique masturbator that’s designed for incredible pleasure whenever you want it. This toy has a ribbed spiral design and you can grip it, squeeze it and twist it for an instant switch in sensation.
This toy has an internal vacuum that’s strong and satisfying and you can control it simply by covering the air hole at the top of your Flex. When covered, the Flex winds and unwinds for stimulating movement. We recommend a water based lubricant with this stroker for maximum pleasure. The Flex is a flexible masturbator with a fantastic texture – it’s also available in white and is easy to clean and maintain.
