APNS-140 The petite-busted beauty is the shared property of her boyfriend’s relatives. Rion Izumi

Rion and Hiroaki, who were classmates, were in a pure relationship that was rare for modern couples, having only kissed so far. During summer vacation, Rion secretly visited Hiroaki’s relatives’ home without telling her parents, but the family had a disturbing custom of “testing” every woman who might become a man’s lover or wife within the clan. Taking notice of Rion’s charm and attractive figure, they gradually led her astray through various situations. After being thoroughly teased and manipulated, she eventually awakened a submissive side and began to desire a more intimate relationship on her own.
