I had no money, no girlfriend, and my only hobby was visiting adult entertainment venues—a dull, unremarkable guy like me. Then one day, while wandering the internet looking for jerk-off material, I stumbled upon a site called "Little Sister Catering." I decided to register, and what showed up was a pure, radiant, orthodox beauty overflowing with innocence! "I'm Haru, big brother—what are we doing today?" she asked, leaving me flustered and tongue-tied. Haru-chan pressed close to me, acting cute and giving me a sweet kiss. I couldn't hold back anymore. I pushed her down and, lost in the moment, began devouring her pure white, slender body. Just lightly touching her pointed pink nipples made her twitch—she was super sensitive! Of course, her clit and pussy were insanely sensitive too, and on top of that, when she straddled me, she kept moaning in a cute voice, "Don't move so much! I'm gonna cum! I'm gonna cum!" With such a cute, serious-looking face, she was an unbelievable slut! Unable to control my excitement, I accidentally creampied her, and Haru-chan said, "Haru belongs to big brother, so let's do it a lot!" So cute—awesome!!
After that, we washed each other in the bath (my boner wouldn't go down, so she gave me a blowjob to finish me off lol), and she made me delicious food (I got horny and teased her with a toy lol). I had plenty of raw sex with Haru-chan, who changed into sexy cosplay! I licked her pink pussy, completely free of any dirt, and fingered it, making her twitch and scream, "Big brother! Big brother!" She carefully licked my dick, which stayed hard the whole time, then straddled me and slid it right into her pussy! Moving her hips vigorously on her own, Haru-chan went full slut mode, soaked with her natural juices. In return, I pounded her from behind, aiming for the depths of her womb over and over! She came so many times I lost count, her body shaking uncontrollably, yet she still wanted to cum more. "All of big brother's sperm! All of it! Please!!" Finally, I creampied her slutty pussy as she begged! After confirming my sperm spilling out, she cleaned up the rest with a post-sex blowjob and even swallowed it all! To think I had such a cute little sister—I want her by my side forever! Haru-chan is mine!!
