When I went back to my hometown, the bath broke, so on the way to the public bath, I met Ai, who lives next door, and she said, "You can use my bath!", so I borrowed her bath. While I was soaking alone in the bath, thanking her kindness, she suddenly came in completely naked! I lost my mind at the destructive power of Ai's nakedness, which I had admired since I was a child... And from that day on, Ai and I became immersed in a short-time affair "only during bath time", with the promise that we would meet until the bath was fixed...
