Mei Uesaka, who had been trained by a perverted man many times, was turned into a sex slave who could wet her pussy just by hearing a man's voice. If the barbed wire was tied tightly to her soft skin, she would writhe with an ahegao face in pleasure. The heartless man continued to blame the body's increased sensitivity to the obscene toy. In the end, the trained body was passed on to the next perverted man, and was toyed with by a stranger countless times.
