Sister and I love each other

Growing up me and my sister have always been super close. We did everything together. Where ever I went I took her aswell. One night we were left alone. We started talking about things and it turned into **. I asked her if she’d done anything with a guy. She said just hugged. Nothing more. She asked the same I told her I’d done everything had ** and oralsex. I started to get aroused. I then asked her if she’d like to see me naked. She said ok I said she had to aswell.
I got naked as did she. I got hard she was surprised that my ** was sticking up. She asked if she could touch it. She then put her hand around it. It felt great feeling her hand on my **. I showed her how to ** me. I got into the mood I asked if she’d like to try sucking it. She looked up at me and said ok. She then put it in her mouth and sucked until I came. I told her I was about to and she kept sucking until I came in her mouth. She swallowed it said it was a salty taste. I asked why she swallowed she said I thought I had to. Oral continued for a few months then She mentioned sec and how that felt. I told her she is a feeling you can’t describe. One night we were watching a movie and she handed me a condom. She said she wanted me to be her first.
We had ** a few times a week after that night. I moved out due to work a few months later. She finished school that same year and came to live with me.
We continued having **. This time she was on the pill so I was able to ** in her for the first time. She then started getting sick. A few days later she told me she was pregnant and the pill didn’t work. She was delighted that she was pregnant by me. I was excited that I was going to be a dad.
She gave birth to a healthy boy which made us both proud. We ended up having 2 more kids together all are perfectly healthy. No one knows the truth. The ** and ** are a dream. Never in my wildest dream did I think I would be this happy. She’s my soulmate we love being together
