My sister (24) and I (32) are secretly in a relationship for years. Things are complicated since she was raped in the past.

*This is a long post*<br><br>I (32) am 8 years older than my sister (24). I also have 3 more sisters. We are an Italian family with 5 children and 2 cats and a dog. We're a traditional familiy. Mom teaches Italian language and literature and dresses like a teacher from a school and my dad is a professor in a university, teaching chemistry or biochemistry and he dresses like a student. That's what our family is like. Mom is a loving mother, father is a stoic professor.<br><br>Ever since we were kids, it's only my younger sister and me who have been close. We also have 3 other sisters, but the rest are not as close to each other, as my younger sister and I are. Our parents have always been happy about that. They'd say we should be close to each other as siblings.<br><br>My sister is very intelligent and learned everything quickly. As a child, she could already talk at the age of 2 very well, learned to read and write and had no problem with math. I'm not as book-smart as her, but good with my hands. She also looks really pretty. She isn't fat, but she has big breasts, green eyes and pretty hair. She always has been popular with boys. I'm on the other side average. I have brown hair, brown eyes, regular face, 6'2 tall and not fat. I work as an electrician for a company and she's a software developer at a big tech company in the USA. She is very smart and a masculine woman. She's very good with computers, plays Dota and a masculine sport. She loves hiking, camping, rock climbing, badminton and fencing. She's very sporty, I always thought she's very cool. I'm not as good at sports, but I'm good at fixing and making things with my hands like robots, Legos and electronics. I always loved her. She's always been my best friend. I love her always dressing up like a tomboy. I'm the opposite of her. I'm very emotional. I also love dressing up nicely and I love music, reading, writing and making art. She doesn't like any of that.<br><br>One day, something happened. At some point when she was 16, she got raped at a party. I wasn't there. I was 24 back then. I'm 8 years older than her. That rape changed everything. She wasn't the same anymore. She became very masculine and sporty. Before that, she liked theater and ballet and was very feminine. After she got raped, she changed completely. She stopped with theater and ballet and started with martial arts, badminton and fencing. She's very good at it now. I guess it was a way to cope with what happened. She became very angry. She'd constantly blow up at everyone. I was the only one who could calm her down. She didn't trust men anymore. She became very cold. She stopped painting and doing music, although she was very good at it. She stopped going to school because she was too angry all the time. She didn't trust men anymore and she'd constantly argue with everyone.<br><br>That's when I became her rock. I was the only one who could calm her down. I knew how to always talk to her. I'm a very empathetic person and I'm very emotional and I always was there for her. I could always calm her down from her anger. She'd call me day and night and I was always there for her. I gave her a shoulder to cry on. I was her best friend. She trusted me more than anyone in the world. I could make her laugh. I'm very good at doing voices and making faces and she loved that. I could always make her laugh, even on her darkest days. She said I saved her life. She said I was her emotional crutch. I was happy to be there for her. I always loved her and I was happy that I was able to help her.<br><br>One day, something happened. She was 18 and I was 26. She told me she felt sexually frustrated. I always knew she was beautiful, but I never dared to flirt with her. I didn't want to ruin our sibling relationship. But she flirted with me first. She told me she was sexually frustrated and asked me if I could satisfy her urges. I was happy and did. I was very nervous, but I said yes. We were both very nervous. I'll never forget how she looked. I'll never forget it. I was so nervous, but I did it. I was able to satisfy her urges. It was the best moment of my life. I was so happy and she was happy too. She told me later that she loved me and that she was so happy that I was able to satisfy her urges. She told me she was sexually happy and she thanked me for that. She said I was always there for her. She said that I saved her life twice. Once from her darkness and later from her sexual urges. She told me she loved me. I told her I also loved her and that I always had loved her. We hugged each other and kissed. And since that day, we are in a romantic relationship. We are secretly in a relationship for 6 years. Our parents don't know.<br><br>It's not always easy. Since she was raped, she's a very angry person. She's constantly very angry and she blows up constantly. I have to calm her down all the time. I'm the only one who can. I'm the only one who knows how to talk to her. I know how to calm her down. Sometimes, I also get angry. I'm a very patient person, but sometimes I'm also angry. But I always try to be patient with her. Sometimes, she's so angry that she breaks things. That's okay. I don't mind. I'm also happy when she's happy. When she's happy, I'm happy too.<br><br>Now, we live together. She lives with me in a big house with a big garden. We have 2 cars. I have a big Jeep because I love big cars. She has a small Smart. We are both happy. We have a big dog and 2 cats. Our dog is from a shelter. We saved him. We also saved the cats. The dog is very big. He's half wolf. He's very loving. The cats are also very loving. We are a big family. We're a big happy family. We're a traditional family. We dress up nicely. She dresses up like a tomboy, I always dress up nicely. She has green eyes and I have brown eyes. We are a happy family. We have dinner together every night. We eat Italian food. Mom sometimes cooks for us. We visit our parents regularly.<br><br>She's very intelligent. She's a software developer for a big tech company. I'm not as book-smart as her, but I'm good with my hands. I'm an electrician. I work for a good company. I make good money. We're rich. We have an expensive house and 2 expensive cars. We are a rich family. We are happy family.<br><br>Sometimes, she has flashbacks. She woke up in the middle of the night. She cries. She's in pain. That's when I have to comfort her. I talk to her. I calm her down. I hug her. That's when I have to be her rock again.<br><br>Sometimes, I'm also angry. I'm a very patient person, but sometimes I get angry too. When she blows up at me, I feel hurt. But I have to be patient. I have to be her rock. I have to be her crutch.<br><br>I'm happy to. I'm happy to be her rock. I'm happy to be there for her. I love her so much. I'm happy to be her boyfriend. I'm happy to be her partner. I love her. And she loves me too. And we are happy. We are a traditional family. That's what our family is like.
