My Girlfriends Mother

I'm Bevan 26 married to Sherry 25, we met at university and hit it off straight away. I'm from a well off family and didn't need to work while at university, Sherry lived with her mother Susan war widow 42 and had to work to support herself thru university. After Sherry and me became serious and had started fucking, Sherry suggested I move in with her and her mother Susan. So we could see more of each other. I agreed as I only renting anyway instead of staying at my home with my parents and the rent would help Sherry and Susan more than my landlord. I moved in and shared Sherry's room and we regularly fucked, with Sherry working odd shifts to pay her way. I was home with Susan a fair alone and one night she had a little too much to drink and I got to fuck her as well and after when Sherry got home I fucked her as well. I'm no angel and usually do what I want, I got Sherry pregnant in 2019 and so we married 2 months later. This was a blessing for Sherry as she didn't have to work anymore, as being in my family now. My family started to pay her university fees and increased my allowance to provide for us both. But I didn't tell them I had also gotten Susan pregnant the night I took advantage of her being drunk. But we weren't really worse as a result as my father Robert quickly guessed I was the father as no other man was around Susan and she had mentioned she hadn't dated since her husband Henry died 4 years earlier. So he increased my allowance again, he wanted it kept under wraps and out of the news. My mother Grace became very attentive to both Sherry and Susan after Robert told her of my actions. I'm a only child and pretty much had things my own way growing up, Grace now had 2 grandchildren on the way and that what took her interest the most. As Susan was pregnant to me and Sherry was happy with marrying me, I pushed my luck as they say and asked Susan to join us in bed and continued a sexual relationship with her and having threesomes with Sherry. I passed my courses with flying colors as they say and Sherry in her last year now and also doing well. On her finishing the 5 of us will move in with my parents, Sherry already has a job at the family firm as do I. Susan is to be my P A, Roberts idea as she had problems with our sons birth and can't have anymore children so Henry is her last . So Robert thinks if Susan is my P A I can't play up too much and keep it in my extra large family. Sherry has also missed her latest period and my be pregnant again. Grace is hoping for a girl this time. As Sherry also had a boy Robert after my father and Susan had boy Henry after her late husband. Grace looks after the children when we are are out working or doing whatever. She gets on with Sherry and Susan and is as thick as thieves with Robert says. As soon as Sherry finishes her courses we all heading back to the family estate and Robert will be happy we're all together fulltime. The estate is only 20 miles out of town, but it's a lot quieter than at Susan home. Which is up for sale and hasn't yet had an offer.
