Six weeks ago I went to my fiancee's house, only to find her mom Mandy supposidly drunk and semi naked on the couch sprawled out. I'd forgotten my fiancee was going to a rehearsal, so I was going to just leave, when I heard Mandy say in what I thought was a drunken fashion "Just put it in me, I need you". She was facing away by then with her bare asshole and pussy facing me. I'd always fancied her, so thinking she wanted me to fuck her. I got my cock out, started to stroke it as I played with her pussy. Mandy began to get all husky with her voice, telling me to "just do it". So not bothering to try and find a condom in my fiancee's room, I put my hard cock to her pussy and thrust in.

I fucked my future mother in law for about two minutes, before she spun over quickly and said "What the fuck are you doing". Putting my cock away quickly and sitting on the chair oposite her. Mandy sat up, covered herself up and asked me why I thought I could just fuck her. When I told her what she'd said, she told me she was on strong medication which sometimes made her very drowsey, and it also sometimes had the side effect of making her talk out loud when she slept. She went onto say she'd been dreaming of having sex with her late husband. I was totally embarrassed, but she told me she'd forget it, if I didn't say a thing to her daughter. For the next hour, I sat there as if it was quite normal to have fucked my fiancee's mother. When my fiancee came in she asked me if everything was ok. It was her moms answer which made me embarrassed and go bright red all over again, when she said "Every things fine honey, ...... and me were just having some fun with each other before you arrived".

Every time I've been back round since, Mandy has made various comments alluding to what I did. Some of them, I think, pointing to her regretting she stopped me fucking her. I'm not saying I would, actually I am. But it would sure make things kind of complicated.
