Takashi, a virgin, hears from a friend that women also have sexual desire and masturbate, and out of curiosity, he gives his older sister, Minori, a large amount of aphrodisiac. At first, he succeeds in watching Minori masturbate as she becomes horny as planned, but Minori, who has become too drugged up and forgets herself, finds her, grabs her cock, and takes her virginity. After that, until the medicine wears off, at home with no place for her parents to escape, Minori, who has become an obsessive slut, attacks her many times and squeezes out all of her sperm.










A younger brother impulsively gives his sister an aphrodisiac he got from a friend. It's not like he liked her or had a plan; it was just in the heat of the moment. The sister finds her own arousal suspicious and interrogates him. 'What do you think you're doing giving me this? Take responsibility. You're a virgin, right? I'll let you do it.' It's incest where she treats him like a vibrator without any real affection. They have sex, but it ends with a handjob. They might have been going for realism, but honestly, it's boring. After the brother tries to escape her insatiable libido, she catches him, makes him watch her masturbate, and then forces oral and hand stimulation. Then, the sister bursts into the bathroom while he's bathing, wearing a swimsuit that becomes transparent when wet, for some light soap-land style play. Finally, she says 'let's have sex' and they do the deed. No kissing, just thrusting until he finishes on her stomach or butt. It ends with the brother basically being treated like a pet. Misato Kanan's bright, energetic sadistic sister act was fitting, but that's the only good part. The script is dull, the play is bland, and it feels as cheap and convenient as a convenience store bento. If you like being bullied by a sadistic older sister, maybe it's for you, but I'd rate it under 3 stars. I didn't give it a 2 only because of the actress's charm.
