念願の一人暮らし。自由を満喫するはずだった……のに、友達の彼女が毎日のように泊まりに来る！無防備な寝姿、見えてしまう下着、ノーブラの胸元。触りたい！でも手が出せない。だって友達の彼女だから…。募る想いと溜まる一方の性欲。限界を迎えた深夜、オナニーを見られて射精直前のフェラ！「もっとしよ」彼女の口から出たその一言で、もう止まれなかった。朝になっても、目覚ましが鳴っても…！そして不器用な告白。「ずっと前から好きだった」。友達から恋人へ。草食男子の一週間の物語。

Finally, I'm living alone, something I've always dreamed of. I was supposed to enjoy my freedom…but my friend's girlfriend keeps coming over to stay the night! Her defenseless sleeping form, her underwear peeking out, her bare chest without a bra. I want to touch her! But I can't. Because she's my friend's girlfriend… My feelings grow stronger and my sexual desire builds up. In the middle of the night, when I reach my limit, she catches me masturbating and gives me a blowjob right before I cum! "Let's do more," she says, and I can't stop. Even in the morning, even when the alarm goes off…! And then, an awkward confession. "I've liked you for a long time." From friend to lover. The story of a week in the life of a passive guy.
