My wife and I got into a big fight during the day, so I decided to go to a box helmet. As luck would have it, I ran into Hibiki, the most beautiful mommy friend at my son's school. We both felt awkward but she reassured me by saying, "It's our little secret." Despite feeling guilty about cheating on my wife, the thrill of having someone more attractive than her remove my load was overwhelming. Before I knew it, we were moving towards another round inside the box helmet.

妻と喧嘩してむしゃくしゃして昼に箱ヘルにいく僕は、息子のクラスで一番綺麗なママ友ひびきとばったり出くわしてしまう。気まずくなったが「私とあなただけの秘密ですからね」と優しくひびきに抜かれる。一度、抜いてもらったことへの罪悪感もあるが、自分の妻よりも綺麗なママ友が抜いてくれたことへの背徳感が悶々と渦巻いてしまう。気がつくと箱ヘルと足が動いていた。
