Colt Hefty Probe Inflatable Butt Plug by CalExotics

Some plugs offer one fixed size, but the COLT Hefty Probe, made by CalExotics, lets you decide how full is full enough. It starts slim and smooth for easy entry, then grows on your command until the fullness feels just right.

Insert it while it's soft and unfilled, and getting into position feels easy and unhurried. Once you're comfortable, squeeze the bulb gradually and feel the plug expand step by step, building that sense of fullness at whatever pace suits you. The quick release valve stays within reach the entire time, so if the pressure ever feels like too much, you can ease it back down in an instant. That control is what makes this inflatable butt plug satisfying for slow build up or for a fuller feel from the start. Use it solo to build sensation gradually, or work it in as a warm-up before other anal play.

In latex with a phthalate-free PVC hose and bulb and an ABS quick release valve, this flared-base anal plug is waterproof and best paired with a water-based lubricant.
