Fantastic. It’s great to read about your experiences, it’s very much like mine/ours. My wife cheated on me many times and like you I spotted her panties in the hamper and saw that they were semen stained. Well many years later I haven’t fucked her in over 8 years and she has a boyfriend whom I really like and get along with very well. He’s extremely well endowed and knows how to use it too. And like you, I get more enjoyment masturbating to the sounds of her moans and screams and the sounds of him going in and out of her obviously very wet pussy. Good for you, I hope your wife still has a good boyfriend and you’re not touching that anymore 🙂
