Large Silicone Inflatable Plug by CalExotics

Some plugs stay one size. This one grows with you, thanks to a squeeze bulb that lets you build the fullness at your own pace. It starts slim for an easy start, then expands as you pump, so you control exactly how much sensation you want to work up to.

Insertion begins easy, with a tapered tip that eases past the initial stretch without a fight. Once you're settled, attach the hose and give the bulb a few squeezes to inflate things gradually, adding length and girth until it feels just right. The silicone body flexes and moves with you rather than staying rigid, and once you've reached your size, you can detach the hose entirely and the plug holds its shape on its own, freeing you up for hands-free play. The flanged base keeps everything securely in place throughout, whether you're using it solo or with a partner, and its suction cup lets you mount it to a flat surface or use it with a harness for a change of pace. When you're ready to finish, the release valve lets the air out gently so removal is calm and controlled rather than abrupt.

This CalExotics inflatable plug is made from smooth, phthalate-free silicone with ABS plastic valve components, it is fully waterproof, and it's easy to keep clean with a mild soap or toy cleaner before and after each use. Once you've tried this inflatable anal toy, a one-size plug will feel like a downgrade.
