Kanna is a serious and intelligent female college student attending a national university. Despite her mature demeanor, her striking beauty and slender figure stand out with an almost un-Japanese elegance. This is her first experience with grinding, as a thick 3cm cock slips wetly through her panties into her pussy. Gradually getting wetter, her erotic scent fills the air as her rational mind collapses, transforming her into a lustful girl who starts grinding her hips on her own. Teased relentlessly, she gushes girlcum uncontrollably, unable to hold back any longer. Finally, the massive cock plunges deep inside her, making her body convulse with pleasure, her face rolling back in ecstasy with a lewd, blissful expression. Her mind long gone, she begs, "I want more cock," thrusting her hips desperately. Even during blowjob, she pleads for more, receiving a massive creampie deep inside her. Afterward, her expression makes one thing clear—she'll never go back to ordinary sex again. Her very first grinding experience becomes a shocking moment that completely transforms her mind and body.
