My sister became my personal maid for three days.

My cute but strict sister finds a hidden test and gets extremely angry. I was able to get 100 points through my hard work, so I got a maid. I spend this three days alone with my sister and I spend everything. What your master says is absolute, but when your real sister comes out and does something sexy, he listens to your orders, even though he's grossed. Hatsukawa Minami's tsundere maid work is so good that you'll gradually become obedient! !
