I have a low sperm count and haven’t been able to get my wife pregnant over the last two years we have been trying We decided fertility treatment was too expensive and after alot of talking decided to ask our college age neighbor who looked like me when I was younger if he would be willing to help out. My wife is 35 but still has a great body and ass. He has a girlfriend but they live long distance so he enthusiastically said yes.
In June we had him over for dinner and after a few drinks him and my wife went up to the bedroom. We were all super nervous but I gave them about 15 mins before I went up to watch. They were casually masturbating each other totally naked and she was telling him not to be nervous that he was doing her a huge favor. He then got on top of her and fucked her really good. Hard and fast and shot a big load inside her. They fucked 3 times a week all through the summer until he had to go back to college. By July I was comfortable enough that he could come over when I wasn’t home. My wife works from home and on two occasions when I got home from work early I caught them fucking. As time went on the sex became more passionate and he starting to make my wife cum which I think helped her finally get pregnant. We found out right before he left to go back.
As a thank you I let her give him a nice sexy blowjob as a parting gift before he went back to school.

She said when he comes back during thanksgiving he can have some fun with her pregnant body which I’m all for.
