MIDE-470 My sister became my exclusive maid for three days. Akiyama Shoko.

My kind but strict sister always lectures me about my test scores. If I get good grades, she says she'll do anything I say, so... I made her into a maid. On the day my parents went on a trip. She obeys everything the master says, but sometimes her true self comes out and she does perverted things, yet she still follows orders even while angry. It feels too good, making her gradually more obedient. Autumn Mountain Shoko's first full-fledged maid work!!
