one night in a certain park. girls with "pien" faces and "jirei" makeup flock to the "support facility's older brother" believing he is their only place to go. but behind that, the worst trap that takes advantage of their trust awaits them. "i fought with my family and don't have money for a hotel..." "i've given too much money to my host and have no money..." "i've been taking more and more sleeping pills..." every time they reveal their weaknesses, a glass is offered to them with a gentle smile. "it will calm you down if you drink this (heart)" the hellish aphrodisiac sex begins from the moment they drink it. at first, they try to refuse, saying "no... something's wrong..." but their bodies are too honest and twitch and convulse. opium faces, squinting eyes, drooling, foaming at the mouth, cumming wildly until they lose consciousness!
