NGOD-018 Husband called to check on me while he was having sex with the neighbor

I'm Yusuke, due to the nature of my work, I often go back and forth to my partner's company. I was attracted by the beauty of the employee at the reception desk here. I approached her and invited her to eat and watch a movie. She agreed and not long after we were officially dating. By now we are preparing to get married, the wedding will be held in mid-June. I am very happy and proud that everyone is jealous of me for marrying such a beautiful wife. But that happiness was quickly replaced by shame, awkwardness and humiliation. Nomoto is a long-time partner and acquaintance of mine. He is 5 years older than me, is a salesman at an underwear manufacturing company, is good at talking and is a genuine playboy. He was very close with Aki, the two of them were always laughing and joking with each other even when I was there. But I think it's because Nomoto's personality is always cheerful, so that's it, there's nothing wrong with it. But I was wrong! At the end of May, my golf date with my partner was canceled. I bought a cake to Aki's apartment and wanted to surprise Aki, but I accidentally witnessed a scene that I couldn't believe!!! She and Nomoto are having fun doing it together!!! I tried to control myself because the wedding was about to take place, but things were going beyond my limit! Making me have to make her make a choice: Me or him!!!
Good movie here:
