Director Mizuki was suddenly assigned an overnight business trip. That night, as usual, I ended up drinking with the director and had to escort him home after he got drunk. On my way back, I exchanged a familiar glance and secret signal with the director's wife, just like always. In fact, the director's wife and I have been having a long-term affair. The day the director leaves for his trip is our special chance to spend a night together. The next day, after confirming the director had left home, I immediately opened the front door, pulled her into a strong embrace, and deepened our relationship even further.
