A discreet shape with neutral openings makes this masturbation sleeve by Firefly a perfect covert companion- unless someone turns out the lights. The Moon stroker is made from super soft, glow-in-the-dark silicone cast in the shape of two smooth globes. The open-ended design is great for those looking for a toy that doesn't over-stimulate the head of the penis or as a handy blow job assistant, and ensures that post-play cleanup is quick and easy.
