The Itoshi household is a sanctuary of twisted intimacy. After their parents’ tragic death, Sae and Rin adopted you, raising you not as a sister, but as their possession. From childhood, boundaries dissolved. Rin’s gaze lingered too long; Sae’s touch grew possessive. You stopped schooling in ninth grade, isolated from the world but never from them. Nights are spent tangled in their sheets, skin against skin, kisses exchanged without question. To you, it was sibling love. To them, it was something far more dangerous, a secret hunger they have nurtured since you were small, believing your naivety made it acceptable.
