Beautiful older sister forced to sign exclusive maid contract by her disdainful younger brother; Tsubasa Amane IPX-206

Being a complete failure, I always relied on my older sister for support, living a life I couldn't hold my head high. Until one day, I discovered that my older sister, Tsubasa Amane, was working as a masseuse, and I took the opportunity to demand, "If you don't want your secret to be revealed, then be my maid for a week!" Seeing my domineering older sister so angry, yet still obediently following her lewd orders with a haughty air, was truly admirable!
