Two G-cup Classmates Study Camp At My House! Erotic Things At Every Break! Yuri Adachi, Mirei Uno

My childhood friend Yuuri and I have known each other for 10 years. She often hangs out at my place, joking around like a guy friend. Lately, Yuuri's best friend, Uno-chan, also started coming over. Uno-chan is popular with the boys in class, and I felt a sense of superiority or happiness. Gradually, after school, my home became their hangout spot... One day, my parents and Yuuri's parents go on a trip, and we decide to have a study camp at my place, including Uno-chan. I thought we'd just chat normally and study together under one roof. After a study session, as we get into our futons, 'Have you two ever had sex?' Uno-chan suddenly blurts out, and an awkward silence fills the air. From there, things start to go off the rails... 'I have, with a senior two years above me.' 'Want to study sex too?' 'Huh, what are you doing??' 'Study sex with me too?' 'Not fair, let me join.' 'You really love boobs, huh.' 'Hey, which one feels better?' Before I knew it, every break we'd devour those white, glossy big breasts and fuck wildly like animals in heat, in a fierce 3P.
