Wild guess here, but there are a few things you'll probably want in a perfect butt vibe. Power, obviously. Tons (seriously) of flexibility? Definitely. The Lust-n-Dreams Tango has both—and more!
 
Let's get into the flexibility thing first. Tango's curvy penetrator bends backward, forward, and side-to-side, so it'll adjust to any position as you play.

Down below, an equally curvy rocker base tickles your outer hot spots as it stops your vibe from slipping too far. One button controls ten vibration modes.

The silicone Tango is body-safe, easy to clean and care for (wash it with mild soap and water or use a favorite toy care fluid/foam), and compatible with any water-based lube you love. This vibe is USB rechargeable (the cord is included) and splash-proof. Please don't submerge it.
