[Emotional Story] An Extraordinary Sibling Romance① (Forwarded)

My sister is actually my aunt's daughter, which is my cousin. She's only a few months younger than me. But because our families are so close, I'm the only son, and my sister is my aunt's only daughter. And my mom really wants a daughter, so basically our family treats my sister as the family's daughter, and she often comes to live with us. I still remember when I was little, I loved sleeping with my sister. Back then, I didn't want to sleep with my parents, but liking to sleep with my sister was really strange. Even stranger, my sister loved sleeping with me too. I would often hold her hand and tell Mom: When I grow up, I want my sister to be my wife, I want to be with her. At those times, my sister would smile sweetly, and Mom would always laugh heartily and say, "Okay, okay, okay." When you grow up, I'll let you marry your sister as your wife. What a silly child...... At that time, my biggest wish was to grow up quickly. Although I didn't really know what it meant to grow up, I knew that when I grew up, I could marry my sister as my wife.
Gradually, we really grew up. I should say our family background was pretty good. In high school, I grew into a fairly handsome boy, and my sister became widely recognized as a beauty.
At that time, I had just started to understand some things between men and women. Watching my sister become more and more beautiful, I started to have some very strange feelings, feelings even I didn't understand.
In high school, my sister and I attended the same school but were in different classes. At that time, people at school had already started dating. I admit I matured late in this regard. When my friends started discussing which school girl was prettier, which guy had already lost their virginity, and how many women they'd been with, I was still sweating and fighting on the football and blue fields, or entertaining myself with Jin Yong's novels. Actually, I wasn't bad—well-proportioned, tall, and considered a handsome guy.
My sister was obviously much more mature than me; maybe girls usually mature earlier than boys! Back then, my sister was widely recognized as the campus beauty, and since my aunt's family was well-off, many people liked her and had secret crushes. The bolder boys even sent love letters and flowers. There were several times it even caused a big stir, alarming the whole school.At that moment, I always felt a bit strange. In my eyes, the other girls were nowhere near as good as football. But my sister was different. She was like a piece of flesh in my heart, and I was afraid someone would take her away.
At that time, I already knew that it was impossible for me and my sister to be together. If we were together, it was incest. Don't ask me where I got that word—I didn't know, I just knew. So I had to force myself to accept that my feelings for my sister were only siblings to numb myself.
Several times I asked my sister, 'So many boys like you, but you don't have one.' My sister always stared at me wide-eyed and seriously said, 'I don't like those things. Pretending to be romantic, giving love letters and flowers—so cliché!' I like those sunny, sporty boys with a sense of humor—they make me happy and safe. I said: You've read too many novels, haven't you! How could that be! My sister said: Aren't you exactly that? Haha...... Even though my sister was just saying it, I still felt a bit off. This feeling has accompanied me throughout my three years of high school.
