Colt Inflatable Butt Plug by CalExotics

Start small, end however full you like: the Colt Inflatable Butt Plug slides in at a manageable size, then grows to whatever fullness you're chasing with a few squeezes of the attached bulb. It gives you control over the sensation instead of asking you to commit to one fixed size from the start.

Insertion happens easily since you're working with a regular sized plug at first, no wrestling with something oversized before the fun even starts. Once it's in place, squeezing the soft bulb gradually increases both length and girth, so you can build up the pressure and fullness at your own pace, pausing wherever feels right. The quick release valve lets you deflate just as easily, which makes pump-deflate-pump play simple whether you're edging solo or working it into partner play during oral or intercourse. The flared base narrows at the neck so it stays put without inflating along with the rest of the plug, keeping this inflatable anal plug snug and secure throughout.

Made from flexible, phthalate-free latex with a smooth surface, this CalExotics design is fully waterproof and cleans up easily with soap and water or your favorite toy cleaner. Keep it simple: rinse well, let it dry fully, and it's ready whenever you are.
