The age-gap couple, 'Hinano' and 'Atsushi.' Atsushi works as a shift leader at a gyudon restaurant. He met Hinano while helping out at another branch and fell in love at first sight, leading to their relationship. They spend their days visiting each other's homes and being affectionate. Even at work, they exude a lovestruck atmosphere, and everyone around them watches over them warmly as an officially recognized perverted couple. Atsushi loves Hinano's cute Kansai dialect reactions and often teases her, making him a mute pervert S character. Just seeing a restrained woman makes him able to eat three bowls of gyudon. Hinano also doesn't mind being tormented; she enjoys being played with and humiliated—basically, anything that feels good. However, even Hinano has ambitions… While researching AVs to please her beloved boyfriend, she first learned about 'syachou play.' Always treated like a child and bullied, she won't be able to act like a woman this way! At an age where she wants to try harder, she thinks, 'I'll become a syachou and make Atsushi beg!' But in an instant, she was counterattacked by her S boyfriend! Tied to the bed, her sensitive ears and neck are tormented, making her cry out. Her nipples are already rock hard. Her vagina is flooded. She's penetrated deeply by Atsushi's huge, hard member, and with sadistic, intense pistoning, she orgasms over and over! 'Now it's my turn to tease!' While having a coworker film, she desperately tries to make him cum with deepthroating, but betrayed by her coworker, she's restrained again! 'No way no way! Why only me…' Even as she screams this, Hinano's body is honest, and she ends up exhausted as usual. Next, she's forced into a bunny girl outfit and subjected to blowjobs and spanking training games. She struggles in agony from intense cunnilingus and choking sex, and finally, he cums inside her. 'Tomorrow for sure… Tomorrow is Hinano's turn to be the syachou…'
