She negotiates, then agrees.

"...would you be open to removing whatever fucking curse you put on me if I agreed to your terms?" she asked, carefully testing the waters, no pun intended, with her question, still glaring at him.

He mulled it over as he started eating his eggs. "Hmm... Well, it'd be kind of redundant to do so, seeing as you'd no longer do the things that made it take effect, but if you insist..."

"...then fine, I agree to your terms," she sighed.

"Excellent, now sit up and wiggle your boobs around," Natsu ordered, taking another bite.

"Yes... Master..." she grumbled, before shuddering slightly as a pleasant sensation passed through her. She pulled herself to the edge of the tub, and began shaking her boobs about, and bit her lip as she felt the sensation once again.

Natsu grinned, and quickly finished his eggs as he watched the blushing and lightly scowling Aquarius turn her head away. He then wrote a little something in the Note to negate the fish order, and considered what to make her do next.
