両親の旅行で7日間、無職ニートで童貞歴48年の超ド変態おじさんのボロ家に預けられた、勉強嫌いな姪っ子・かなちゃん。薄暗い腐敗部屋に閉じ込められ、毎日「7の段」を延々と耳元で囁かれ、強●視聴させられると…最初は「キモい！やめてよ！」と暴れていたかなちゃんの瞳が、だんだん虚ろに…。 「おじさんの言うこと…全部正しい…」脳がとろとろ溶け、抵抗する力も理性も消え去り、自分からスカートをたくし上げ、パンツをずらして幼い割れ目を差し出すまでに堕ちていく。 7日目の夜、完全崩壊。
Kana-chan, a niece who hates studying, is left in the dilapidated house of her uncle, a jobless NEET and 48-year-old virgin who is a total pervert, for seven days while her parents are away on a trip. Locked in a dimly lit, decaying room, she is ****** to watch the "7 times table" whispered endlessly in her ear every day… At first, Kana-chan struggles, crying out "Gross! Stop it!", but gradually her eyes become vacant… "Everything Uncle says…is right…" Her brain melts, her ability to resist and her reason disappear, and she falls so low that she lifts her skirt herself, pulls down her panties, and offers up her young vulva. On the seventh night, she completely breaks down.
