After a year on the job, I've gotten used to my work and have been relying on the guidance of my senior colleague Yuuki. On that day, as usual, I was at work when Yuuki's wife, Chitose, came by to deliver a lunchbox. Going to greet my senior's wife, I was instantly fixed on her voluptuous body, something I had never seen before. Then, a few days later, when I went to visit Yuuki who had a severe backache, Chitose invited me to dinner, her ample cleavage and large hips on display as she asked in her defenseless state.
