Think

Cassandra took a moment and thought about what had just happened. Specifically with the piercing. She picked no. She said out loud she wanted more money. Her phone got a new message. Same offer of a piercing but now with more money.

So whatever weird ancient magic or sci fi alien science was going on someone somewhere on the other end of her phone was paying attention to her and was willing to bargain to get what they wanted.

And as she did before she spoke to her phone, "I would need a lot... a loooot more money for bigger boobs. And how much depends on what kind of breasts you want to give me. Big stupid bimbo balloon boobs would be at least a million dollars. Per boob. Regular human woman large breasts would be much less."

Cassandra pressed the NO button, taking a deep breath she looked at her phone screen and waited.
