Kasumi and Mitsuki are notorious troublemakers who have driven away their previous home tutor, prompting their mother to hire the MC as their new instructor. Despite Kasumi and Mitsuki insisting that he’s not necessary, their mother is determined to improve their misbehavior.
However, things begin to spiral out of control as the mischievous sisters find themselves under the MC’s increasingly depraved discipline sessions. Kasumi is pushed to perform sexual acts that leave her feeling helpless, and in an effort to protect her more innocent sister, makes the self-sacrificing choice to take on all the MC’s desires.
As the tutor’s depravity escalates, Kasumi becomes fully consumed by the pleasure, unable to resist the MC’s grip with Mitsuki at risk of being exposed to the same savage punishment.
