My Return

I'm Clifford 38 and had been overseas for almost 12 years, going straight after university to a great job. I had a 10 year contract and the corona virus stopped my return earlier, my family is only my Sister Sarah 34. Our Parents passed away in a car accident in 2016 and no other close relatives. Sarah is a quiet person by nature and married Arnold at 27, Arnold is quite a bit older than Sarah and she soon found out she was for display and not building a family. Arnold is gay and used the marriage to hide that from his family and church he belonged too. Anyway in 2020 his parents got the virus and didn't take care and passed away. Also his minster got it (2021) and also passed away, that caused Arnold to leave the church and so he decided to come out as gay. But first he divorced Sarah and she was well rewarded for her loyalty as he saw it, getting the home and a large cash payment. Arnold then left to start anew (his words) and shortly after I returned home. I went straight to Sarah and I took her skiing and we had a holiday together. I rented a cabin as Sarah doesn't like crowds and we could be alone if we wanted to be. I'm not the greatest when it comes to dating, but that didn't matter while overseas and I got regular sex. Paying for most of it, but it kept me satisfied sexually. Being alone around Sarah, I got horny not because I was sexually attracted to her. But I had become use to regular sex while away and it had been almost a month since my return. At the ski lodge everybody else seemed to be with someone and that only left Sarah and when alone at our cabin it was a strongest. But I was holding it in check, until I saw her topless. This cause me to get really horny and I made a move on her. If she had said stop I would've, but she didn't and I fucked her. I was surprised that she was still a virgin and her and Arnold never had sex during their marriage. But once I fucked her I was hooked and I wanted sex more and more with her and she always let me have my way with her. No Complaint from her at all, on getting back to her home I moved into her bed and have stayed there ever since. I never took any precautions and she got pregnant last month she had tests that show the baby is healthy and I'm quite content with our relationship. But decided to make official, going abroad and marrying Sarah using our passports and returning back to her home as man and wife. She says she is happy with being my wife, lover and most of all my sister and I'm very happy to have her as my wife.
