A beautiful high school girl on her way home from club activities recreates the traditional 48 positions! Can I do it in the right pose? The ones taking on the project are Rei-chan from the prestigious swimming club and her tall coach. "I don't hate you, teacher, but I'm embarrassed..." We start by observing the two who can't be honest with each other. They hesitantly exchange kisses, and start with cowgirl cunnilingus in "Iwashimizu". Her fair, beautiful breasts are teased in "Mukudori", and then she moves on to close-contact insertion in "Matsuba Kuzushi" while holding one of her legs. "Are you okay, teacher?" Even though she's trembling in a perverted position, Rei-chan cares for her coach. The coach even happily drinks up her pee. The creampie instruction for the two lovers escalates as they switch from uniforms to competitive swimsuits. Her slender beauty might just burst with semen!
