Another day of sales calls with the beautiful and diligent Yuri Sasahara, but an unexpected issue forced us back to the office. Buried in preparing estimates, we suddenly realized it was already late at night. The entire building was empty—only Yuri and I remained. We grabbed dinner and drinks from the convenience store, chatting and drinking together, when suddenly the power went out. In that instant, Yuri tightly embraced me from behind, pressing her warm body against mine—and I couldn't help but get aroused. When the electricity returned, we decided to spend the night at the office. Later, I woke up to the sound of the shower. Peeking quietly, I saw Yuri alone, pleasuring herself.
