I was slow and clumsy, always looked down upon by my two older sisters, living a timid life... But one day, I discovered that my sister Tsubasa was working at a delivery health escort service. Seeing this as my chance, I gave her an order: "If you don't want your secret leaked, be my maid for a week!" The tsundere charm of my strong-willed sister obeying my erotic commands while angry and sulking is irresistible! With her exquisitely cute pouting face, this is Tsubasa Amami's first classic maid role in six years!
