My Drunken Neighbors

I've 2 neighbors Donald and Marion both in their thirties and they live together, but aren't married. I'm Brett 45 divorced and live alone, Donald and Marion goes out every Friday night get drunk and then fight all day Saturday. I was quite happy living peacefully and not doing much except work. One night they really got drunk and passed out on the front stairs. As it was a cold night I got them inside and put Donald on the lounge and was putting Marion on a chair near the table. I had her leaning on the table while pulled the chair out to sit her in. It was then I moved her dress up and saw her panties and I got horny. So I fucked her draining my balls into her, then I put her into the chair and left. Now months later they aren't getting drunk anymore as Marion is pregnant and Donald cannot remember fucking her at the time she got pregnant so he told me. I asked did you two getting really drunk and maybe had sex and can't remember even getting home. Yes he said, that's when it happened I said. So I'm the cuckoo in their nest, at least it more peaceful now.
