He had a great body, but had trouble staying hard with me in the room so I only saw him finish inside her one time. As his orgasm started, he pulled on the first spurt went on her belly but then she ordered him to finish inside and the rest went in her. The aroma of cum just filled the room and my wife looked absolutely radiant and happy. That's the hottest moment of all! From then on, we invited him to our house when the kids were with their dad, and I stayed out of the room until he was spent. As a young guy, he always had two or three loads for her. It was pretty messy when she was ready for me (usually while he was dressing to leave). We still joke about how I wasn't really getting "seconds," - it was "thirds, fourths or fifths." Her subtle way of letting me know where I stood in the broad scheme of things.
