One day, my sister-in-law came over to visit us. Later on that night, my wife asked me, "Can you take Heidi home?" I said sure. As we got to her house, her kids were asleep in the back seat. She asked me to help take the kids in. I said sure. So, we put the kids in bed. I said, "Have a nice night, Heidi," as I got to the door and turned to say good-bye. At first it seemed like a normal hug for us, but I could really feel the warmth from her breasts. The next thing I knew, we were kissing each other like crazy. Then she said, "I see how you have been looking at me over the years. I've wanted you so much." We made love for an hour and a half. I had to leave, so we agreed not to do it again. Yeah. Sure. We make love at least fifteen times a year. Her husband works with me. It's the best sex I ever had, and nobody has a clue.
