I'm making drawings in my notebooks, and my brother comes from school, he asks to see what I'm doing and I show him why I admire him a lot. He tells me that my body is growing more and more and he admires me too, he likes how my body is evolving and I am becoming a great girl, it makes me very excited, I am happy to hear it from him. He says that we are going to play something more fun than coloring, I accept and he tells me to take off a shirt, I still don’t wear a bra, because I’m a little sister, he is terrified of how big they are in my breasts, and asks to I squeeze them and play with them, I feel something strange, a good and delicious feeling, I keep playing with them until he takes off his pants and asks me to suck his dick, he says again that it is a fun game, and I I suck, I drool all over, I keep sucking, he looks at my ass and says it’s really big, and asks me to get up my panties, a little more, I get up ... He asks me to take it off, asks me suck it more and then I ride it, as if it were a little horse and when it's over I suck it until it comes in my mouth. He asks me to put the clothes on quickly, that mommy is coming and he doesn't want to play anymore.
