和美と俺は同僚で、お互い付き合ってる人がいる。…なのに俺たちは●っ払い、気付けばホテルにいた。会社では見る事のない、無防備な和美の寝顔。酒の勢いも手伝って、俺たちは本能のままに朝まで何度もセックスしてしまった。「ねぇ、ゴム破けてる…」「えっ!?」何回目の発射だっただろう。和美の声に血の気が引いた。だけど何発も出したし、精子も薄くなってるから大丈夫と自分に言い聞かせた。そのまま何事もなかったかのように出社した俺たち。…いつも通りのはずだった。なのに和美が俺に言った。「ねえ、責任取ってよ?」…かくして、一夜限りの関係だった筈の俺たちは付き合うことになり、それから何度も何度も浮気セックスを重ねた…。 Kazumi and I are colleagues, and we're both in relationships. …Yet we got drunk and before we knew it, we were in a hotel. I saw Kazumi's defenseless sleeping face, something I never see at work. Fueled by alcohol, we gave in to our instincts and had sex over and over until morning. "Hey, the condom broke…" "What!?" I don't know how many times I'd ejaculated, but Kazumi's voice made my ***** run cold. But I told myself it would be okay since I'd ejaculated so many times and my sperm was diluted. We went to work as if nothing had happened. …It should have been just like always. But then Kazumi said to me, "Hey, will you take responsibility?"…And so, what was supposed to be a one-night stand turned into a relationship, and we cheated on each other again and again… –
