Little Sister Massage!!

The story follows a young man whose father remarries, leaving him to adjust to life with his new stepsister, Kano Arise, a striking university student. She initially gives off a reserved, somewhat gentle impression, with a far more assertive and affectionate side to her beneath the surface. The two gradually become aware of the unusual dynamic created by their new family relationship, and begin to move beyond their roles as stepsiblings through their everyday life together.​
