Doki Doki Breast Expansion Club It is important to join clubs in college in my country of Japamerica, and so I let myself be talked into joining a club by Sumiko, my childhood friend. Sumiko has a crush on me, but I quickly become interested in the busty Yumi. It seems like all the girls have a thing for me, and once they realize I love big breasts, things start to get very strange. Bold and Busty Olivia has always loved to show off her big breasts. That was why becoming a stripper was the ideal job for her. When she meets Chris, a mysterious man who shares her obsession with big breasts, she starts to grow, and is on her way to having a bust to fulfill her wildest dreams.
