Mei Uesaka, who was repeatedly trained by a perverted man, was turned into a sex slave who could wet her pussy just by hearing a man's voice. If the hemp rope were tied tightly to her soft skin, she would writhe with an ahegao face of pleasure. The callous man continued to blame the body's increased sensitivity to the obscene toy. In the end, the trained body was transferred to the next perverted men, and was toyed with countless times by a stranger.
