Can an inflatable be used to restrain?

I have an overactive imagination today! I was thinking about using an inflatable (vaginal or anal) to capture or restrict a person from moving. For example, attach an inflatable to the seat of a chair, a floor, a pole or any immovable object. Then have the person sit on or insert the inflatable, then inflate to a point where it will not or cannot be removed by pulling themselves of it. They are bound to where they sit, stand or lay until to Dom deflates it and they can pull themselves away from it.

I assume anal wouldn’t require much inflation. I know with an inflatable at even 3 inches it would be impossible for me to pull away from. Vaginal, depending on the individual, it would have to be much larger.

Neat idea, and I think it'd be a lot of fun to play with. However, I don't think it's escape-proof. Years ago, I had an inflatable butt plug. In free air, it would inflate to 5" (or so) diameter. Inside me, I'd inflate it until it was pressing firmly against the walls of my rectum, and then pull it out. It was about 4.5" or so in diameter. Being flexible, as it's drawn through the smaller anus, it deforms being reduced in diameter, and temporarily becoming longer. Once free, it springs back to its normal, inflated shape. Still a hell of a lot of fun. Go for it!

Not inflatable but a pear of anguish will do the trick.

@masterkinkster I see you're a man of the trade 😃 ... Username also checks out.

I also question the practice as being escape proof. I think that a catheter would be much more escape proof.

This certainly can be done. However, based on my rudimentary knowledge of anatomy, the uni-sex solution is one to aim for. Unlike rectum that is closed with sphincter that can provide 'locking' point, vagina is long muscle 'tube' and does not have a sphincter at its entrance. It means the inflated object can be eventually pushed out. As long as there was no physical damage caused, that I assume is not the intention here.

Of course, the victim has to be prevented from reaching to the plug otherwise they will simply deflate it. Additionally, the plug itself has to be not too big at its max capacity, so it is possible to inflate it fully to prevent what @LDB described. This happens because there is enough capacity in the plug to push all air far enough so part of inflatable section can be pulled out. This does nor happen with balloon nozzles as long as they are fully inflated.

Ok, this got my mind going. A inflatable girl toy, has a strap on. I'm butt up, she is on top, long strap on deep in my butt. Only thing I am wiggling is my butt. Real girl would be preferred with the strap on, but I would want her to have a butt plug in her butt until it is time for me to slide in and give her a cum enema.

You may see this referenced as a “one bar prison” or “one pole prison/restraint”. Although it doesn’t necessarily require an inflatable plug, it could certainly be adapted to use one.

In this technique, a pole with adjustable height is securely attached to the floor and topped with a dildo or other penetrative device. The recipient stands above it and the pole height is adjusted such that the device is buried in the recipients orifice. Typically the recipient is a woman in heels to prevent her from raising her height to escape. In this manner it’s “impossible” to escape as there is no way to raise yourself high enough to dismount.

Seems that one could get impaled on it if they slipped!

If the dildo/plug/whatever was mounted on an "L"-shaped piece off the side of the tall pole, the potential impalee (new word) would be caught by that and not be impaled. The amount of padding on the mount would determine the comfort of the imprisoned victim.
