MOMMY Sperm Donor

It's been a while since my husband pay the debt of nature. I am a single step-mom now, still young and fertile and desperately looking for a sperm donor. And while I analyse the options a weird thought came across my mind. Since me and my step-son have a very special bond, and I am already ovulating I ask him to naturally try to breed me and make me a mommy again. His hesitation turns me on because I know what we're going to do is so wrong, but I am not to blame as long as no one finds out.
