職場の上司だった丈さんと結婚し、もうすぐ半年が経ちます。一見すると、何不自由無い幸せな暮らしですが、私には悩み事が二つだけありました。一つは丈さんの連れ子である浪人生の史郎くんと、いまだ不仲であること。もう一つは、丈さんとカラダの相性が良くないこと。張り切ってセックスをしてくれるものの、どうしても満足できず、私は、欲求不満を抱えていました。しかし、そんな私の不満気な表情も、つまらないセックスも…すべて史郎くんに覗かれていたのです。そして史郎くんは「親父のじゃなくて、俺のを今日子さんに挿れたらどうなるかなって。」と無邪気な性欲と反り立つ肉棒を私にぶつけてきて…。

It's almost been six months since I married Takeshi, my boss at work. On the surface, it seems like a happy life with no worries, but I had two worries. One was that I was still on bad terms with Shiro, Takeshi's son from a previous marriage who was studying for his university entrance exams. The other was that Takeshi and I weren't physically compatible. He would try his best to have sex with me, but I could never be satisfied, and I was left feeling frustrated. However, Shiro had been watching all of my dissatisfied expressions and boring sex… And then Shiro said to me, "I wonder what would happen if I put mine inside you instead of your dad's," and he unleashed his innocent sexual desire and erect penis on me…
