The cute but strict sister always lectures me about my test scores. She said if I get good grades, she'll do anything I say, so... I made her a maid! Whatever the master says is absolute, so she says 'I'm your sister though…' while accepting sex. My sister, who initially resisted my dick, eventually started to crave it... A tsundere maid work featuring Soru Aizawa's cuteness and sexiness!
