Mion, the stepchild of her remarried partner, has recently become noticeably more mature. She feels adult pleasure with her aphrodisiac oil after her stepfather massages her feet, which were hurt during club activities. I train her in aphrodisiacs when her mother is not home. She is finally made into a body that craves her aphrodisiac and her stepfather's dick... She convulses in agony so much that her thin waist seems to buckle! ``My father-in-law will do anything, so please give me more.''
