The bond between sister and brother is tested! In front of the younger brother who enters the room where the restrained sister waits, there is a mission of "100,000 yen for every time you make your sister squid" and an adult toy! At first, the mission was supposed to be for money, but because of the woman's face that my sister shows every time she is made to orgasm with a toy, my brother's sexual desire is ignited, and the two dabble in forbidden incest. Complete recording of the situation!
