I am a normal office worker with a girlfriend. My senior colleague is Karen, a very gentle, kind person with an extremely attractive figure. Today, Karen and I were working on documents for tomorrow, but we couldn't finish in time, so she had to stay with me. Suddenly, a heavy rain started pouring down, and the train was temporarily stopped, so I couldn't go back. Seeing this, Karen invited me to stay overnight at her place, as her house was quite close to the office. Although I knew it wasn't appropriate, I had no other choice at that moment. When we arrived at Karen's house, both of us were completely soaked. When I looked at Karen, I felt frozen. The rain had made her thin shirt cling to her body, revealing her skin and underwear! Unable to resist her seductive appearance, I ignored everything and rushed to take her, ejaculating inside her wet pussy!
