Fun with Sis

I'm Mathew answer to Matt 37 divorced 2 children who live their mother Rhonda 34. After the divorced I bought myself a new house 4 bedroom, I prefer to work from home and late last year my sister Grace 33 came to stay with me until she found own. Grace is a little overweight and has low self esteem issues and as I wasn't having my children for Christmas I decide to make Grace's Christmas special. We lost our parents in a 2020 car accident before the pandemic stuck. I wasn't dating and so I was going give Grace a great time and to that end I took her away to the coast for 3 days over Christmas. She has a fuller figure with curves in the right places, but isn't as slender as she thinks she should be. Rhonda has a slender body like Grace wants and is only 10 pounds lighter than Grace. Grace put on a one piece swimsuit and I got horny just looking at her. But I took her to the beach for a time then back to our hotel room. Anyway she said she was going to shower and I asked did she want me to wash her back, adding Rhonda loved me washing her back in the shower. Okay Grace said and I joined her in the shower both naked and I got a hard-on and Grace seen it and asked me did I want to fuck her. I said yes please and again got an okay from her so I fucked her in the shower and for the rest of our trip and on return had her move into my bedroom with me. In January Rhonda and her partner Joyce broke up and as our house was sold because of our divorce, she was living with Joyce. So she and the children moved back in with me, Rhonda quickly worked out I was fucking Grace. But she also wanted fucking by me to satisfy her sex needs and she also started with Grace also. Which meant the 3 of us were sharing the same bed and by April I had gotten Grace Pregnant and all tests so far show the baby is fine, not to be outdone Rhonda is now pregnant as well (late May). So I've remarried Rhonda and have Grace and her in my bed every night. Fun with Grace and I'm back with my wife and still fucking my sister as well.
