The person in charge of the big job was surprisingly beautiful, but also had a charming smile and an easy personality. We went out drinking as part of work and drank a lot, and although I was drunk, I still had my senses. I don't know how she felt, but that day we had the best sex of my life. Since then, whenever I wanted to jerk off, she would contact me, carefully licking my member, which was tired and dirty after a day's work, and shaking her hips violently but gently, making me even more excited. I had the best mistress in the world.
