Marriage has been 8 years now. Since the second year, I wanted to have a child, so I almost made love to my wife every day. But before having a child, I got tired of her body. It has been a few years now since the two of us have not made love. One day, Amatsuka moved to live in the apartment next to ours. From the first look, I was attracted to her beauty and cheerful personality. The next day, I saw Moe struggling outside the door, it turned out she had forgotten her keys inside and was waiting for the locksmith to help. Since we had to wait a long time, I invited Amatsuka to come over for a meal. Afterwards, my wife and I along with Amatsuka drank wine and chatted. After a while, my wife went to take a bath, leaving just me and Amatsuka. I don't know if it was because of the alcohol, but I touched Amatsuka's hand and she did not pull back. Taking advantage of the situation, I was about to kiss Amatsuka when my wife came back in, and we quickly returned to our original positions. Although we didn't do anything, we both silently acknowledged our feelings for each other. The next day, Amatsuka pulled me into the house. The two of us kissed and hugged for a while, and I wanted to go further. But Amatsuka stopped me, feeling it was strange to make love right next to my wife, so she wanted to wait until she goes on a trip next month. Throughout this month, I had to restrain myself, not having sex with my wife or masturbating, and Amatsuka would endure the same as me. And a month of such torture has come 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 into each other like two animals, releasing all the accumulated sexual desires over the past month...
