Yuri, who attends the same university as me, is the first girlfriend I ever had as an Amateur virgin. Just being with her heals Kokoro. When I took off her clothes, I was 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, plump body, which I couldn't imagine from her clothes, I could only think about sex. Wrapped in her soft breasts, my dick was already fully erect. She's a shy girl who doesn't associate sex with sex, but when it starts, she's too erotic...! A motherly female college student aiming to become a nursery school teacher, and a naughty girlfriend who will do anything for her boyfriend at night! The two of them just started dating, but they love each other so much that they have sex all day long without even realizing it!
