Tsukamoto went on a business trip with his female boss Tachibana. Because this trip took two days, tonight both of them had to stay overnight at a hotel. The company recently had a cost-saving policy, so they only provided one room for the two of them. With no other option, they had to share a room. Tsukamoto had long been fascinated by Tachibana's seductive body, and this seemed like a heaven-sent opportunity for him. After walking all day, Tachibana felt a bit tired, so Tsukamoto offered to give her a massage. But he didn't just massage her, he continuously touched and caressed Tachibana's body, even daring to touch his boss's private parts. When Tachibana went to the bathroom, he could freely watch her masturbating inside. Knowing that his boss also desired sexual pleasure, the next night, while she was sleeping, he boldly had sex with Tachibana despite her weak resistance. After that incident, Tachibana seemed to open up more to him, allowing him to enjoy intimacy with her on the condition of keeping this secret from everyone.
