Constricting, constraining and sexily tugging on one of your or your penis owning partner's most overlooked (generally speaking!) sweet spots, the Ouch! Glow In The Dark Ball Sack slips fully over a scrotum of choice, stretching and stimulating during sex or stroking. Oh, and yes, it glows in the dark! 
Adding a little weightiness and sexy snugness over the base of the balls, the Sack stretches easily to fully surround the..well...sack! For some folx, the sensation of the Sack makes for a super-intense finish. Slip it on pre-playtime, or have a partner position it during playtime - the choice is all yours.
In skin-safe silicone, the Ball Sack cleans up quick and easy using warm soapy water or a good toy care fluid/foam. This toy is compatible with any favorite water or silicone based lube. 
* The Ball Sack is about 3.15"/8cm long. Inside, it stretches from about 2.75"/7cm long and .98"/2.5cm in diameter
