While working, I received a phone call from Riho-senpai, she was on an important business trip but forgot to bring the documents. Therefore, Riho-senpai asked me to bring the documents from the company to her. After finishing the task, it was already late, so we had to stay overnight at this place. Since we didn't prepare in advance, we had to share a room together. It was at this moment that I realized Riho-senpai's true intention, she deliberately forgot the documents to call me here! She kept using her seductive body to seduce me, knowing my sensitive spots, playing with my nipples and penis, making it impossible for me to control myself! From midnight till morning, she didn't let me rest for a single minute. I don't know how many times I ejaculated, all I know is that all my sperm was completely drained by my beautiful female boss!
