Due to an unexpected turn of events, I found myself alone with my friend's wife at his house. She teased me with a panty shot. Just lightly touching her made her arch back and react intensely; when I inserted my dick, her innocent appearance was completely unrecognizable as she convulsed all over and came hard. To save face for my friend, I held back from ejaculating to avoid pregnancy, but she smeared semen into her vagina and tempted me to have internal ejaculation. This is a story of cuckolding.
