Where had that dignified, beautiful, and graceful wife gone? It was a mystery—until one day, she suddenly vanished. It all began when she took on a health device monitoring job to repay a debt incurred by chance. However, this device was no ordinary piece of fitness equipment; it was a specialized apparatus designed to immobilize the human body. Once strapped in, her movements were completely restricted, leaving her utterly helpless. In this restrained state, her body was taken over by the salesman's cock, forced to endure relentless manipulation of her own genitals. Day after day, she suffered under his control. Yet, as she bore the torment, she gradually succumbed to the salesman's cock, eventually responding with a pitiful expression, submitting helplessly to his actions.
