An office sex movie by Karen Yuzuriha, my junior, a smart, beautiful, cute and extremely innocent girl. Today, Karen and I were assigned to negotiate with a client. Because I was subjective, I almost ruined the job, fortunately Karen was extremely sharp and got the contract. After that, we both went out to celebrate. Because I drank too much, I missed the last train, and my phone ran out of battery. Karen immediately suggested that I go to her house to recharge my phone. Thinking that if I didn’t do anything, it would be fine, I agreed. When I got home, Karen immediately wore a loose, off-the-shoulder shirt that made her breasts constantly appear before my eyes. Because Karen usually wore suits, I didn’t expect her breasts to be so big and beautiful! Knowing that I was peeking, Karen immediately confessed to me. It turned out that she had liked me for a long time but hadn’t dared to confess. Unable to resist Karen’s seductive beauty, we fucked each other all night long, Karen also let me cum all over her pussy again and again.
