Like me, Muscle Junior is also a former athlete. The day I realized there was no professional world for the sport I loved, I felt a despair that still haunts my dreams. That's how dedicated I was to sports. As if to fill that frustration, I now spend my days sweating through sex. That's when a certain woman caught my eye. Kasumi-chan, a "sporty beauty attending Nippon Sport Science University." An 18-year-old who has experienced various sports since childhood and dreams of excelling in both "sports and education." She has an innocent personality, fair skin, a slim, toned waist, and a plump, beautiful ass. This beauty exploded her hidden sexual desire and squeezed every drop of cum from Jiro. After seeing the amateur footage of her, Junior called me, which is rare. "I'll show you hot sex with Kasumi-chan from Nippon Sport Science University, so please let me fuck her!!" Hearing Junior's eager words, reminiscent of when we first met, I felt nostalgic and wanted to see athletes having sex. That's how this project came to be. Please enjoy this work where sexual desire, cum, and sweat fly everywhere. Kasumi-chan appeared in sexy clothes that showed off her white skin. "This is super sexy, right? ♡" The sexiness of the mesh detailing along her waistline. It's a man's nature to want to untie things like that. Since it was her first day off in a while, Kasumi-chan also actively played with Junior's nipples.
