But since we moved to work, we have never seen each other again. A year later, I returned to Tokyo for the first time on a business trip here. I contacted Airi and expressed my desire to meet her. But Airi was extremely cold and refused. I was bored sitting drinking at a bar I used to frequent, and suddenly Airi appeared and sat next to me. She was prettier than my wife and we got along very well in sex. Since I didn't have much time, I quickly hugged Airi, shooting all the sperm that had accumulated for a long time into the depths of her.
