On an ordinary afternoon, uniformed beauty Mizukan sits alone on a park bench. Shy and misunderstood, she's isolated at school. A seemingly kind ex-teacher approaches. 'It's for your own good,' he says – the start of a nightmare. Gentle at first, listening to her woes, but his 'justice' twists into dark lust. 'You need a lesson with your body!' He preys on her shyness; it's no education or love, just an excuse for his cravings. Crying and terrified, she can't resist. Her pure mind and form crumble, overtaken by forbidden ecstasy. Innocent schoolgirl vs. twisted uncle hiding behind fake righteousness!
