Some plugs stay the same size from start to finish. This one grows with you. The Butt Balloon, from Nasstoys, is an inflatable vibrating butt plug that starts slim and expands as you squeeze the bulb, letting you build fullness gradually instead of committing to one fixed size.Insertion starts easy thanks to the smooth rubber surface and a flared base with a narrower neck, which keeps things secure and stays put once it's in place. From there, the squeeze bulb is yours to control: pump it up for more fullness, or hit the quick-release valve when you want to deflate and start again. That pump-and-release rhythm is where the real fun lives, whether you're using it solo or bringing a partner into the mix for extra prostate or G-spot pressure. Once inflated to where you like it, the built-in vibrator kicks in with multiple speeds, and the wired remote's simple twist dial means you can adjust the intensity without breaking your rhythm. The suction cup base also lets you set it down and go hands-free whenever you want your hands elsewhere.Made from rubber with a smooth finish, this hands-free anal toy runs on standard AA batteries (not included), is fully waterproof for play in the tub or shower, and cleans up easily with soap and water or your favorite toy cleaner.
