Take advantage of the water.

Natsu sat back as Lucy recovered. He was getting to really enjoy Lucy as a bimbo... He decided he'd keep her like this until the morning. But for now, he remembered Lucy had another sexy Celestial Spirit, begging to be used. He reached for the Sex Note and the pen in his clothes, and grabbed it, writing, "Aquarius will be unable to attack Natsu Dragneel, or Lucy Heartfilia, and when Summoned by Lucy outside of combat situations for Natsu, or leave until dismissed or Lucy runs out of magic, she will immediately take her top off..." He decided he'd decide on further adjustments after getting a read on her.

"Hey Lucy, your keys nearby?" he asked.

"Oh, yes, I like, keep them close, just in case!" she winked. "I mean, you've totes shown me my house isn't like, secure, apparently," she quipped.

He simply chuckled. "Mind calling Aquarius then? Don't worry, I got something for her attitude," he smirked.

"Sure!" she grinned, grabbing the gold key. "Like, Open, Gate of the Water Bearer!" Aquarius came out, and glared at Lucy, seeing her naked in the tub with Natsu.

"What... What the hell is the meaning of this!?" she demanded, setting her water jug down, and then reaching up behind her and undoing her top. "Wait, what am I doing!?" she shrieked, blushing as it came off, and she quickly covered her tits up.

"The hell did you do!?" she demanded, glaring at Natsu. "I know that hussy who Summons me isn't capable of this!"

"Hey, that's like, super hussy to you!" Lucy shot back, crossing her arms under her tits as she puffed out her cheeks.
