Because the incompetent manager made the data in the report inaccurate, manager Sasaki and I had to go to the office to work on Sundays. The air conditioner was broken, the weather was hot, and we couldn't clock in. While we were working, Sasaki came to check on my progress. She leaned close to me, her sweat revealing a part of her skin, reminding me of yesterday. Yesterday, when I was about to meet the manager, I accidentally saw the manager and the manager making love, and I also knew this manager because this Sunday was his twentieth wedding anniversary with his wife, so he made us go to work in his place. Coincidentally, manager Sasaki's birthday was also on that day, but he decided to put the manager's birthday aside to be with his wife. He always promised to divorce and always asked Sasaki to satisfy him sexually at any time, no matter how tired she was. He even ejaculated inside her and forced her to take birth control pills!!! Thinking about that and the summer heat made me gradually unable to control myself anymore. I wanted to bring her happiness, wanted to take her away from that damn department head.
