We'll gather only busty college girls and hold a breast weighing game! We'll invite all kinds of types, such as skinny busty girls, innocent busty girls, black gal busty girls, and petite busty girls, and the team that first reaches a total breast weight of 10,000g will be the winner in a team competition! The winner will receive a prize! The college girls will be told by the game host that if they perform a breast development technique called "Pie UP", "they will instantly grow larger due to the increase in hormones", and their bare breasts will be played with!
