I would do anything for my son and his wife. When I noticed how much she has been struggling because she is not pregnant yet, I immediately offered to help. She has been doing everything she can, checking her temperature, logging every shift in her cycle, and tracking hormones like it was her full-time job. She thinks there is something wrong with her, but I know better. In fact, I've helped breed a lot of women before, so I know that this is never their fault. All she needs is to get a real man's seed, and if my son is not up for the task, she can have mine. She doesn't want to cheat on her husband, but she is so desperate to get pregnant, I know she is not going to say no to having her father-in-law's dick inside her, and I was going to make it worth it for both of us.
