Beautiful Older Sister Signs Exclusive Maid Contract With Despicable Little Brother Tsubasa Amami

"I was always looked down on by my two older sisters, living a cramped life as a slow and clumsy guy... But one day, I discovered that my sister Tsubasa was working at a delivery health service. Seeing this as my chance, I ordered her: 'If you don't want me to spill your secret, become my maid for a week!'... The tsundere way my strong-willed sister angrily and sulkily obeys my lewd commands is irresistible! That perfectly pouty face is incredibly cute—this is Amami Tsubasa's first maid-themed work in six years!"
