"Now then, Player Quinn has rolled a six. That means she has landed on the body modification square. And since she rolled an even number, that means I shall decide your fate."
"Wait, what do you mean?" she asked nervously.
"This is the Game of Change, Player Quinn. Do not fret, since you are the first player, I shall be gentle."
"Wait, can't I-AHH"
The youngest sisters hands recoiled upwards, slamming against the thin fabric of her revealing tank-top. An overpowering, uncomfortable ache had exploded within her mammoth melons. Something inside them was changing, though she couldn't tell what. From what she could tell, it wasn't her breasts that were changing. Rather, it was something inside them. A foreign object, one that was steadily growing. Unused to such a feeling, she let out a groan of discomfort, drawing the concern of her family.
"Quinn, are you okay?" Cosima asked.
"N-no, something feels weird with my tits! Somethings g-growing in them..."
To emphasize her point, Quinn reached up towards her dug her fingers into the thick breast flesh. Though merely intending to draw her family's attention to the change, her squeeze sent whatever was inside her tit shooting out. Her swollen nipples exploded in pleasure as a jet stream of breast milk shot out, soaking the fabric of her top. Her nipples too had grown rock hard, pressing themselves against the top in eager anticipation of further milking.
"Oh my God," Quinn yelled, "I'm lactating!"
"Yes, I figured it was fitting, considering you were the bustiest here," the game explained.
"How long will I be like this?"
"Forever, assuming you don't get a transformation to change it back."
Before she could even complain, another ache blasted through her bosom. Much more powerful than before, it was almost painful. The growth was faster, too; Quinn could feel the milk expanding at an exponential rate. It didn't take long for the dairy liquid to fill the inner cavities. She collapsed backwards in discomfort. And the milk wasn't the only change, either. Her breasts had swollen due to their new cargo, expanding her already massive E-cups straight into F-cup territory. Her expanded tits overflowed the already tight-fitting tank-top, breast fat spilling over the sides. Thankfully, Quinn was the type of girl who didn't wear bras in the house, leaving the experience more embarrassing than it was painful.
"T-this is awful." she complained. "It's like I'm some pregnant cow..."
The rest of the group exchanged awkward glances. They realized there was little they could do to help Quinn. Instead, their thoughts turned to what was next. Who was going to take the plunge and roll the die? To their disappointment, it seemed the game was going to decide for them.
"Enjoy the lactation, Player Quinn. If you need a breast pump, just ask and I can provide you one. Or your family can help relieve you, it matters not. In any case, with her change complete, let us move to the next round. Player Rachel, please grab your token and die, please."
Rachel's eyes widened at the news. She didn't want to play, but what was she to do? She swiped the red token, causing it to mirror her figure. It didn't change much; her flat features meant that the token was pretty much her already. All it grew was her hair and a bulging belly. One look at the token left Rachel feeling self-conscious, but she pressed on, placing the token on the starting square. She let the die go, rolling a three.
"Very good, that means you have landed on..."
