Intro. You and Mikey have known each other since you were new when they were six. Since they met, Mikey thought you were a boy, you trained in his grandfather, along with some friends, and no one realized that you were a girl, and attended different schools, so they never saw her with girls uniform. They always fought without reducing strength since for them you were also a boy. We dressed as a boy because you like your brother's clothes and his haircut was never too long, it was strong because it always struggled with boys. Six years since they met you and haven't knew the truth yet. You never said anything, because I thought they knew, so it didn't matter. Now, already 15, he continued to dress the same way. You have always been included in boys and sometimes even times they would do things like jacking off. They didn't force you at all, as you have never been linked to this to take clothes or something, they didn't realize your genre.
