A kind yet strict sister who's tough about test scores makes her appearance! I asked her to serve as my personal maid, knowing she promised to obey any request if I got good grades. I planned this while our parents were away on a trip. Though she insists the master's orders are absolute, her true sisterly nature occasionally shows through—scolding me even as she obediently follows my lewd commands. The more pleasure she feels, the more submissive she becomes, creating an irresistibly erotic dynamic. Don't miss Akiyama Shoko's first full-fledged maid performance!
