I moved to the city to attend college, and during a long-overdue visit back home, I found myself excitedly talking about my new girlfriend. When my younger sister Yui learned about her, jealousy overwhelmed her and she clung to me nonstop. She was no longer the girl I remembered—now mature and alluring, she pulled my body closer and closer. Her chest had grown slightly, her soft, shapely figure impossible to ignore. Her blowjob skills had crossed a new threshold, driving my cock into a frenzy. From morning till night, she stimulated me relentlessly, making me cum again and again like a helpless mess. Despite her cute face, the wet, slurping sounds of her blowjob had me rock-hard once more. Even as I prepared to leave, she gave me a long, thorough blowjob until my balls were completely drained. This homecoming became an unforgettable experience—consumed by deep jealousy, and overwhelmed by endless, irresistible pleasure from her mouth.
