My Younger Brother's Wife is for My Exclusive Use Beatrix

Since puberty, I started seeing my younger brother in a peculiar way. Of course, I was still attracted to girls, but at some point, I began mistaking my brother for one. I couldn't grasp my own gender identity or how people determine gender. By my standards, even though my brother is legally male, in reality he exists like a woman. If he were a woman, it'd be natural to fall in love. The idea of brotherhood feels like an outdated social constraint. I don't want a life bound by such dull conventions. One day, I couldn't resist the urge to have sex with him. Playfully, I took his penis into my mouth and delighted as it swelled up. He moaned, "It feels so good... I might actually be hornier than you, big brother... So let's do even naughtier things," inviting me further. I finally gave in to his temptation.
