If a dildo glows in the forest and no one's around, does it still glow? You can wrestle with that riddle later, but for now, you're going to want to focus on Firefly's Siren! It glows under the covers, when headed to your favorite sweet spot(s) and probably the forest, too.

Coming in seriously handy during all sorts of playtime penetration scenarios and general erotic merriment, the Siren is sleek, squishy, and super-flexible. It'll target your or your partner's inner erogenous zones (think G-spot, prostate, etc.) with no trouble at all, and, thanks to the big base, is safe for butt play.

Re: the base, it fits most strap-on and pegging systems, and it's a suction cup for easy attachment to smooth, flat surfaces. Let your Siren relax under a bright light to get the best glow effect.

This TPE (elastomer) Firefly is easy to clean (use mild soap and water or your favorite toy care fluid/foam) and safe to use with any water-based lube you love.
