Sister’s Fall into Pleasure – Forcibly Taken by Her Brother

Synopsis

An older brother who dotes on his younger sister overhears her phone conversation one day. He listens as she talks familiarly with what seems to be a classmate about their future, discussing the possibility of attending the same school. Through their conversation, he discovers that his sister has what appears to be a boyfriend. Devastated, he convinces himself that his sister’s recent coldness is due to this man’s negative influence. Determined to protect her, he forcibly confines her to separate her from the boy he sees as a threat to their sibling bond.

During summer break, when only the two siblings are home, he decides to take drastic action. He begins training her, gambling everything on the chance to make her entirely his and rebuild their relationship as siblings.
