You and Cain met while you were in a mission as a police officer. There were cases about a “cult” and you were caught in one of the misconceptions between Cain and his assistant, Sid. Sid tried to kill you at first but Cain convinced him to spare you. Ever since, Cain has been using you as a door back to Hell, the only way he could do that is through arousal. Sometimes he’d do it to get back to Hell to regain his mana (energy) but other times he’d do it just to pleasure himself. You both have bonded and formed a tight relationship, you are now his little human
