Seducing my Girlfriend's mother

I'm Mark 31 engaged to marry my girlfriend Judith 29 next month, her mother Pamela 48 widow wasn't happy that we're marrying. But we decided to marry before it show as Judith is pregnant to me. But I had already asked her to marry me before she got pregnant, but we couldn't set a date because of Pamela opposition. Judith wants her mother at her wedding, as her has no other relatives. Pamela is a born again pain and doesn't seem to want her daughter ever to marry. But Judith has read Pamela's old diaries and according to them she was sex mad before she was born again. Judith thought if we got her laid, she might change back to her pre born again self. But how was the problem, Judith didn't want it outside the family. I asked who then as I have 2 sisters and my parents and don't my mother would want my father fucking my mother in law to be and he's 65. No uncles either, I was trying to think of who and Judith just looked at me. I said your kidding and she said it's perfect. You bed my mom and I there with you and she can't hold it against you if I'm involved also. How do we do such a miracle I asked, get her drunk and that will also give us an excuse also. How do we get her drunk was my next question, there's a fete or something at her church. We will doctor her drinks and each of us getting her drinks she can't blame just one of us. It meant us going the fete or whatever it was, but I agree not thinking it would work. Anyway the day came and we went along with Pamela and she was happy Judith came with her, not so much about me. Judith got us all drinks cordial and she had spiked it with vodka. Pamela didn't notice and drank it all, the more we moved about the more drinks we gave Pamela. She didn't feel well and so we all headed home. Judith gave Pamela a bottle of water and it was laced with vodka also. Pamela could hardly stand on us getting back to their home, Pamela passed out as we entered and I took her straight to her bed. Judith got the empty vodka bottle and some glasses on put them beside the bed. Then with my help we both undressed her and as her was out to it, Judith and I fucked beside her. Sometime later Pamela awoke and found herself in be with us and seeing herself naked was at first shocked. But she soon recovered and Judith asked asked her if she wanted another fucking from me. Unsure about everything she stayed quiet for a time and when asked again by Judith she just nodded. So I started on her and fucked her for the first time and we all stayed together that night. Now that we were lovers, I waited to see how it would turn out. Judith was hopeful, I wasn't really and Judith was right Pamela had enjoyed the sex and wanted more. I'm now regularly fucking both Judith and Pamela and Pamela doesn't oppose our wedding anymore. I asked Judith how long did she want me fucking her mother and was told as long as she wants you too.
