This is a Flex-TPR cocksling that restricts both the penis and scrotum.
This flexible TPR cocksling is an improvement on Oxball's original design. It acts as both a cock ring and a ball stretcher, but it's flexible enough to match penises of all shapes and sizes. The design also relieves pressure on the underside of your penis, allowing you to urinate easily while hard and slung. Lubricate with your favorite water-based lube before wearing.
