I am a normal office worker with a girlfriend. My senior colleague is Karen, a very gentle, kind, and extremely attractive woman. Today, Karen and I were working on a document for tomorrow, but we couldn't finish it, so she had to stay with me. Suddenly, a heavy rain poured down, and the train was also temporarily stopped, preventing me from going home. Seeing this, Karen invited me to stay at her place overnight, as her house was quite close to the office. Although I knew it wasn't appropriate, there was no other option at the moment. When we arrived at Karen's house, both of us were completely soaked. When I looked at Karen, I felt like time stood still. The rain had made her thin shirt cling to her body, revealing her skin and underwear underneath! Unable to resist Karen's allure, I disregarded everything, rushed towards her, and ejaculated inside her wet pussy!
