なぜ、これほどまでに彼女から目が離せないのだろうか？長野で生まれ育った20歳の女子大生。どこにでもいる「普通の女の子」なのに、この圧倒的な引力は何だろう。華奢な体に規格外のIカップが詰まっているから？いや、違う。素朴さ100％の笑顔の裏に、実は最高にエロい顔とカラダを隠し持っているからだ。可愛らしい笑顔なのに、僕をを興奮させるこの色気底知れない伸び代感を秘めたラスト・イノセント。これは彼女がスーパースターになるまでの物語、その第一弾である。

Why is it so hard to take my eyes off her? A 20-year-old college student born and raised in Nagano. She's just an "ordinary girl" like any other, yet what is this overwhelming allure? Is it because her slender body is filled with extraordinary I-cup breasts? No, that's not it. It's because behind her 100% innocent smile, she's actually hiding an incredibly erotic face and body. Despite her cute smile, this sexiness excites me, and she's the last of the innocents with boundless potential. This is the first part of the story of how she became a superstar.
