A high school girl with black hair who seems plain at first glance is actually an underground idol. She seems to be quietly working in Asagaya. She's a laid-back girl who goes at her own pace, so it's surprising to see her doing something so active. However, engaging in prostitution would be a betrayal of her fans. To punish her, she is blindfolded and attacked with a vibrator. Then, she makes a cute, happy voice. Is she really an underground idol? I wonder, but when I thrust my dick into her, she also makes a happy voice that seems to feel good. Her moaning makes the other girl smile wryly, and she starts moving her hips faster, realizing that she's no ordinary high school girl. These days, underground idol high school girls have unfathomable talent.
