My sister became my personal maid for three days.

My kind but strict sister always gives a sermon about test scores. They say they'll listen to anything they want if they get the good points... and I've been asked to become a maid. It's aimed at the day my parents go on a trip. My master is absolutely gonna say something, but sometimes my real sister comes out and when she does something sexy she gets angry, she listens to her orders. Akiyama Shoko's first full-fledged maid work is so good that she gradually becomes obedient! !
