Synopsis:
Kasumi, the sharp and sophisticated elder twin, prides herself on her ability to manipulate any man who crosses her path. Beside her is Mitsuki, the naive and clumsy younger sister, who views the psychological bullying of their tutors as nothing more than a fleeting amusement.
However, their world is irrevocably upended with the arrival of their newest instructor. Unlike the victims of the past, this man possesses a chilling patience and a repertoire of ruthless tactics designed to re-establish a new, absolute order within the household.
The twins deploy a relentless series of malicious pranks, desperate to drive the intruder away. But to their horror, the tutor expertly twists their own traps against them, using their “misbehavior” as a pretext to initiate endless sessions of carnal discipline.
Faced with a direct threat against the vulnerable Mitsuki, Kasumi is forced into a devastating realization. To shield her sister from the tutor’s escalating cruelty, she must make a harrowing choice: to surrender her pride and offer herself up as a living sacrifice.
