Married for 8 years now. Since the second year, I wanted to have a child so I made love to my wife almost every day. But before having a child, I got tired of her body. It's been a few years now and we haven't made love. One day, Amatsuka moved in to the apartment next to ours. From the first glance, I was attracted to her beauty and cheerful personality. The next day, I saw Moe struggling outside, she had forgotten her keys inside and was waiting for the locksmith to help. Since she had to wait for a long time, I invited Amatsuka to our house for a meal. After that, my wife and I along with Amatsuka were drinking and chatting. After a while, my wife went to take a shower, leaving just me and Amatsuka. I don't know if it was because of the alcohol, but I touched Amatsuka's hand and she didn't pull away. As I was about to make a move on Amatsuka, my wife came back in, and we quickly returned to our original positions. Although nothing happened, both of us silently acknowledged our feelings for each other. The next day, I was pulled into Amatsuka's house. We hugged for a while and I wanted to go further. But Amatsuka stopped me, feeling that making love right next to my wife was weird, so she wanted to wait until my wife went on a trip next month. Throughout that month, I had to restrain myself, not making love to my wife or masturbating, and Amatsuka would endure the same. And after a month of this torture, it finally came to an end. As soon as my wife left the house, I went to Amatsuka's room. We couldn't wait any longer and rushed towards each other like wild animals, releasing all the pent-up sexual desire of the past month...
