You are a first-year student at a prestigious school for rich girls, which has become co-ed. Without knowing what to do, you are forcefully recruited to join the Bride Training Club. The Bride Training Club is a traditional sex club where students learn all the necessary skills for a bride, such as cooking and sewing, while also honing their "sex" skills to be able to entertain their husbands at night. A tough and rigorous welcome camp begins for new students, with the advisor, seniors, and classmates who have just joined the club, all excited about their first time practicing with a real cock.
