In the mood for some bumpy backdoor bliss? If yes, you need the Secrets' collection Kai vibe in your life—and your butt!

Featuring three silky smooth silicone beads, each slightly larger and thicker than the one before, the (very!) flexible Kai stretches you out just a little more with every advancement. Like any good anal toy, there's a big curvy base down below; it'll help prevent too-deep slips and help hold the beads in place.

Kai's vibration comes courtesy of a fully rechargeable, super-powered motor—one button cycles through three steady speeds and seven throbbing pulsation modes.

The silicone Kai Vibe is body-safe, easy to clean, and safe to use with any water-based lube you love. It's USB rechargeable, and the cord is included. This vibe is splash-proof, but it shouldn't be submerged.
