He does, and lets Lucy out.

His hand brushed the lamp, when it suddenly started to sputter. He yelped and dropped it, jumping back, on guard along with Happy, as the lamp started gushing out a shimmering violet vapor. Smoke from some kind of Fire Magic? Natsu inhaled experimentally, checking to see if he could draw it in and consume it with his Fire Dragon Slayer Magic. Nothing happened.

Before he could ask any further questions, or try anything else, the smoke condensed. It all reformed into Lucy, who floated in a serene posture, softly smiling, her eyes closed, and her legs replaced with a tail made out of the odd smoke. Natsu and Happy stared at her extremely provocative outfit. She would actually be less sultry if naked. And yet, instead of reacting with the indignation and humiliation they had come to expect from her occasional, or frequent mishaps with her clothing and exposed body, she seemed quite at peace, and content.

"Mmmm~!" she moaned as she slowly stretched her arms over her head and arching her back, presenting her boobs to Natsu in a way that drew his gaze. Despite generally being disinterested in romance and sexual relationships, and lacking understanding about the nuances of such things, he did have a sex drive, it was just on the back burner as he focused on more important things. He blushed a bit, but didn't look away. He'd look as long as Lucy let him.

"...Lucy?" he finally asked, Happy hiding behind him, a bit nervous about the situation, and not at all distracted by Lucy's exposed state, more confused about where her legs had gone. He was a cat, an Exceed to be specific, naked or scantily clad humans did nothing but amuse him.

Lucy cracked her eyes open, and gasped in delight. "Oh, Master, I am so glad it's you who found me! Then again, it was to be expected, given your penchant for entering unannounced and uninvited!" she giggled, holding the back of her hand to her mouth.

"Wait, "Master?"" Natsu asked in disbelief. "What are you talking about?" He sniffed the air again. Yeah, that was definitely Lucy, but something else. Her scent was very much present, but mixed with the alien one. "Lucy, you okay? Where's the rage you normally have about me coming in? Your embarrassment at being in revealing clothing?"

"Oh, Master, such things are unimportant to me now~!" she scoffed as if actually offended at the idea of getting mad about Natsu invading her space or seeing her exposed. After all, everything she was was no longer hers entirely. She and everything she owned, every aspect of her being belonged to whoever possessed her lamp. And the concept didn't trouble her. She had attained a higher state of being that she loved being in, and the price tag of being a complete and total **** was just another perk in her mind now, given that she had been made as submissive as it was possible to be. Her mind was clear, free of the silly, arbitrary standards humans had when it came to seeking sexual fulfillment. She hadn't even known this degree of ecstasy was even possible!

"...what happened to you?" Natsu inquired, trying to wrap his mind around this surreal experience.

"Oh, I am so glad you asked!" Lucy grinned, leaning forward, beaming in delight as she saw Natsu's gaze went to where her boobs were pressed up as she crossed her arms under them. She most certainly wanted him to ogle her to his heart's content, fulfilling his voyeuristic wants was just another of the duties she enthusiastically embraced. "You see, this lamp isn't part of our normal magic system! It's in fact a relic from a world far beyond ours!"

"What, like Edolas?" Natsu questioned, only for Lucy to giggle.

"Oh, it's way farther out there than that, my Master!" she crooned. "Like, incomprehensibly so... but we digress, the point is, it claimed me, and turned me into a Sex Genie! Now, my powers and I are completely at your disposal! Please, do with me as you wish, I fully welcome it~!" As she spoke, her face took on the expression of a seductress, her eyes half open and reflecting lust and submission, wordlessly begging Natsu to use her, and her lips puckered slightly, partially open in a tiny "o."
