●校からの大親友と上京してシェアハウスで暮らす僕と親友の松本。性格は似ていないが、部活でも受験でも共に努力を重ねてきた間柄だ。そんなシェアハウスに、明るく気さくな巨乳美女の安達が引っ越してきた。根明な性格の安達と2人はすぐに意気投合。部屋は違えど、一つ屋根の下で暮らす3人。日に日に仲良くなっていく中、僕は安達に恋心が芽生える。でも3人の雰囲気が崩れることを躊躇い、思いを言い出せない。せめて、自室で安達に似た女の子が出てくるAVを見るだけ。すると、なんと、安達と松本が先に付き合うことに。さらに、動揺を隠せない僕に追い討ちをかけるような松本からの一言。「俺たちのSEXを撮ってくれないか？」親友のお願いを断れない僕は99％の罪悪感と1％の興奮を胸に松本の部屋へ向かう。「えっ…君が撮るの？」「死ぬほど恥ずかしい…」そこには、夢にまで見た好きな子の裸と元気溌剌だった好きな子の「女」としての姿だった。目の前でイチャイチャを見せつけられ脳もチンコもパニックになりながらなんとかカメラを向ける僕。カメラ越しに見る、「女」としての反応。恥じらいながらも何度も絶頂する安達。SEXを撮り終えた僕はビンビンに勃起していたー。

●My best friend Matsumoto and I moved to Tokyo together and live in a shared house. We're not alike in terms of personality, but we've worked hard together in club activities and for entrance exams. Then, Adachi, a bright, friendly, busty beauty, moves into the shared house. Adachi has a cheerful personality, and the two of us hit it off immediately. We live under the same roof, albeit in separate rooms. As we grow closer day by day, I begin to develop feelings for Adachi. But I hesitate to confess my feelings, fearing that it will ruin the atmosphere among the three of us. At best, I watch adult videos featuring girls who look like Adachi in my room. Then, to my surprise, Adachi and Matsumoto start dating first. Furthermore, Matsumoto adds insult to injury, leaving me still reeling from the shock: "Would you film us having sex?" Unable to refuse my best friend's request, I head to Matsumoto's room with 99% guilt and 1% excitement in my heart. "Huh… you're going to take the picture?" "I'm so embarrassed I could die…" There, before my eyes, was the naked body of the girl I'd only dreamed of, and the vibrant, energetic girl I'd always admired, now in her "woman" persona. My brain and my dick were in a panic as I watched them flirt right in front of me, but I somehow managed to point the camera at them. Through the camera, I saw her reactions as a "woman." Adachi climaxed again and again, despite her embarrassment. After I finished filming the sex, I was rock hard.
