Mary, almost cried. She had just got her breasts, and they were she had grown bigger than the other 3 girls. She Figured at least a C-cup, but the the thought of haveing a dick or balls made her sick. She loved being a girl. So sadly she said 'my breasts'. She felt a sensation in her chest and cupped them. They quickly deflated beneath her fingers to nothing but nipples.
The other girls were secretly happy to see them shrink. Carrie was glad that she wasn't the smallest anymore, and Jill was happy to now have the largest chest of the 4.
Jill was next she confidently rolled a 5, she landed on change 2X. 2 potions came up from the game. She had to Choose Mature or Regress one for her and one for another player. Jill thought for a momment, she grabbed the bottle that said mature and handed the regress bottle to Mary. Even though she had a flat chest she was still the most mature looking of them all. Mary frowned again, she knew the penalties for not going along with the game. They both downed the liquid, and replaced the bottles back on the board, the labels of the bottles shimmered and switched names.
Jill gulped and quickly got up, the changed started. She felt a little dizzy the romm felt like it was growing, her freinds looked bigger, especially MAry. She felt her chest, her c-cup were gone, and they were smaller than they were at the start of the game. She was now younger than 9. The Shrinking slowed and she stopped at what they figured was 5. She was now about 3'6", a good 2 feet shorter than the other girls except Mary. MAry was now at least 5'10", and her chest hadgrown to about a small B-cup. She looked to be about 25.
