It's one thing to slide in a butt plug and enjoy the feeling of having your ass stuffed. It's another to "expand" on that (Hahah), and use the attached hand pump to inflate the butt plug and stretching the anal cavity. When you're done with the inflation, a quick release valve releases the pressure.
Let the Anal dilator do the job, expand the hole.

--High-quality elastic and soft silicone surface
--Super-large expansion rate, inflatable deformation to 10cm
--Waterproof and explosion-proof material design
Jim still wasn’t quite sure how he had ended up bent over a chair and tied down to it with a gag in his mouth. He remembered snooping through his girlfriends closet and finding a cache of very interesting sex toys before being caught by her. She had said that he needed to be punished for snooping through her things. She was very intimidating and forceful about him needing punished and now he was in a position he had never dreamed he would be in. He could feel his girlfriend lubing his ass up and slipping her fingers slowly in and out of his asshole. His cock twitched with each finger insertion. “My, my,” she said, “your ass is so tight I can barely fit two fingers in there, I am going to have to change that.” Jim could feel her start to work the tip of a rubber plug into his ass.
It was nice and slim and pushed in fairly easily being just slightly larger than her fingers were. “I am going to have to work on stretching that tight ass out if you are going to be my sissy slut from now on,” she said as he felt the plug in his ass slightly enlarge. His girlfriend continued, “The plug I put in your ass is specifically designed to stretch out your ass. It goes in nice and small and then I can pump it up slowly enlarging it and expanding your ass to be able to take all those big dildos you found in my closet. I bet you thought you were going to use those on me!”, she finished with a laugh.
She then proceeded to pump up the dilator until Jim was whimpering in pleasure. The inflated plug was putting intense pressure on his prostate causing his cock to be the hardest it’s ever been. “I am now going to leave you here to let you think about what you have done and what your fate is to be in this relationship,” she said as Jim heard the bedroom door click shut.
