I was stuck working late in the office, completely exhausted after yet another round of orders from the department chief. Most of the staff had already gone home when suddenly Sasaki-san, the office idol, cheerfully showed up. She gently offered to give me a massage, saying she was concerned about my fatigue. I politely declined, saying "No, no, I'm fine," but she ignored me and started massaging my shoulders anyway. That's when I realized, "Wait, you're not massaging the right spot!"—and in that instant, I figured out she was using me to get a promotion from the chief. "Alright, alright, I get it. So stop the massage," I said, trying to push her away, but she insisted, "No, this isn't about work." Then, feeling her hands touch my cock, I was shocked when she suddenly said, "Let me suck you." That's when I realized she was just a filthy, insatiable slut. At that point, I couldn't hold back anymore—I made up my mind to fuck her relentlessly and give her exactly what she wanted.
