同じ職場で付き合った悠華は、僕からすれば不釣り合いなほどに自慢の彼女だった。美人で、スタイルが良くて、明るくて、誰とでも仲良くて…。社内の男性陣からの人気も飛びぬけていた。ムカつく中年上司、僕の仲良しな同期、そして入ったばかりの後輩。みんなとうまくやっていて、そんな彼女を尊敬していたのに…。でも、その人気の裏側を、僕は何も分かっていなかったんだ。悠華は、そいつら全員とめちゃくちゃヤリまくっていた。僕が仕事に追われている隣で、彼女は職場の男たちとあまりにも簡単に、楽しそうに体を重ねていた。「もっと抵抗しろよ……。なんでそんな、幸せそうにセックスしてるんだよ……」悔しい。悔しい。悲しい。つらい。はずなのに…。どうしてか、僕の股間はアツくなっていた。「浮気してごめんね」「でもなんでおちんちん大きくなってるの？」ああ、なんで勃起してるんだ、僕は…。
Yuka, whom I dated at the same workplace, was a girlfriend I was incredibly proud of, almost too good for me. Beautiful, with a great figure, cheerful, and friendly with everyone… She was exceptionally popular with the men in the company. My annoying middle-aged boss, my close colleague, and the new junior employee. She got along well with everyone, and I respected her for that… But I had no idea what was behind her popularity. Yuka was sleeping with all of them like crazy. While I was swamped with work, she was having sex with the men at work so easily and happily. "You should resist more… Why are you having sex so happily…" I was frustrated. Frustrated. Sad. Painful. And yet… For some reason, my crotch was getting hot. "I'm sorry for cheating on you." "But why is your dick getting so big?" Ah, why am I erect…?
