I have told this story on at least one thread, but it bears repeating here. When our daughter was a teenager, there was an older boy in the neighborhood who came around to see her. My wife and I were very afraid he might fuck her.
So, she and I talked it over and I suggested she let him fuck her, on the condition that he would let our daughter aloone. She agreed, as I was sure she would and when the made the "proposition" to this young cock, he gladly accepted.
He came to our house about twice a week, while our daughter was at school, and fucked my wife. A few times I was still there when he arrived, but I left quickly, while he waited, awkwardly. He knew that I knew he was fucking my wife, but I didn't think he would be able to talk about it!
It was a perfect situation for everyone concerned. Our daughter escaped being fucked before she was ready for it. This young guy got some "older" pussy, which he really enjoyed. My wife got to get some fucks from a guy who was young enough to be continually horny. And I got the joy of knowing I was married to the kind of woman that young guys would still want a piece of.
