Yuri, who attends the same university as me, is the first girlfriend I've ever had as an amateur virgin. Just being with her soothes my soul. She's always smiling, but when I take off her clothes, I'm surprised to see her plump, G-cup breasts. "What's wrong with you staring at me like that?" Wait a minute...! When I saw her healthy, voluptuous, and curvy body, which you wouldn't expect from her clothes, all I could think about was sex. Enveloped in her soft breasts, my dick was already fully erect. She's a shy girl who doesn't associate sex with anything, but when it does start, she's just too erotic...! A maternal college student aiming to become a nursery school teacher, and a naughty girlfriend who will do anything for her boyfriend at night! They've just started dating, but they love each other so much that they're completely absorbed in sex all day long!!
