Booted from the family

Last year I 19 was caught fucking my sister then 22 and as a result I was kicked out of home and out of the family. I was told it was all my fault as my sister has low esteem problems and I took advantage of her. I went from the favorite to the black sheep, just because I fucked my older sister. But undeterred I still had a job and found my own place to live, nothing flash in looks a rundown old house. Which I made an offer to buy, and it was accepted. I mainly bought the land as the house wasn't seen as worth anything, with help from my buddies we level the house and replaced the foundations and straighten the house. The roof was replaced and with that done, I could live there comfortably. A buddy rewired the place so it wouldn't burn down, and it became our hangout. My mother paid me a visit and told me I'd gotten my sister pregnant, and the tests showed her to be healthy. That was all the contact I had with my family since being kicked out. A week later my sister paid me a visit and me being a smartass as usual asked her if she wanted to fuck. Just to get reaction and I was shocked as she said OKAY and so I fucked her again. She continued to visit and most times I fucked her, as she pregnant and she is always willing. But sex stopped as she got close to having our daughter and in June our beautiful daughter arrived. I'm still not back in the family as far as my father is concerned and he doesn't know my sister visits me regularly with our daughter and my mother comes along also. I think she suspects that I'm still fucking my sister and comes to make sure I don't her pregnant again. But my sister does get to visit me every now and then without our mother and we have sex. I use a condom every time now, I'm happy with my actions. I see they have benefitted me, first I would've gotten my own place unless I was kicked out, second, I have a beautiful daughter with my sister. My sister also feels better about herself now another plus and she is willing to have sex with anytime I ask. The only thing that isn't going well is my relationship with my father and so it's another plus for me as I don't have to try and get his approval for all my actions as before. That I think made the rebellious boy I was, I've changed for the better now, I think of others now and not just myself.
