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 intentions; she deliberately forgot the documents to call me here! She continuously used her seductive body to seduce me, knowing my sensitive points, playing with my nipples and penis, making me unable to control myself! From dusk till dawn, she didn't let me rest for a single moment. I don't know how many times I ejaculated, I just know that all my sperm was drained by my beautiful female boss!
