強力なコンプレッサーによるお尻の極端なインフレーション - 自己緊縛タイマー

Inflatable fetish. A trans mom with a big ass tries out an automatic inflatable machine to punish herself for her fat ass. She handcuffs her hands with electromagnetic cuffs attached to the machine, which unlock when the machine pumps a set amount of air into her. After the handcuffing, the machine measures the pressure in her ass and judges it too high because Mom just wanted to fart. Based on this, it automatically increases the maximum possible pressure and volume of air against mom's will. But she can no longer disengage and can only wait in shame for the machine to do its job...
