Breast Development Strategy: A Certain Girl's Summer Vacation

A small adult game focused on breast growth. The player character earns money through part-time work and breast milk sales, then invests in supplements and new bras to follow various growth schedules. The game features dynamic growth mechanics based on actual data rather than preset values, with all progress recorded for varied playthroughs. Visual content includes 12 static CGs and 3 animated CGs, each with 5 size variations that unlock as the character's bust grows. The game contains masturbation and nipple depiction but does not include standard sex scenes.
