We are in our 60's. My wife cuckolded me in our second year of marriage. It took 2 more years to catch her. That was devastating. I was too insecure to leave her after she told me my dick was so small it couldn't satisfy anyone. I knew she was still seeing the man with the huge dick. Sometimes it was so loose when we had sex I knew she was seeing him. I began to fantasize about what it would be like to watch her. It began to give me erections thinking about it. She finally agreed to let me watch. It was even more devastating. I couldn't believe she could take anything as large as his cock but it disappeared to his balls easily. I had never seen her orgasm as often or as intensely. Even as devastated as the sight was to be I came without being touched.
Afterwards we talked. I acknowledged there was no way I could do that for her. We agreed she could do whatever she wanted as long as she told me about what she did. After the super stud moved away, she started seeing a fellow teacher that was black and just as well hung. They have been getting together for the last 16 years. When she comes home, I clean her pussy as she tells me the details. Everyone is happy.
