Slave.

"Alter Ego: Slave," Natsu said, making Lucy blink at the switch flipping in her mind.

"Master..." she cooed, still covering herself. Natsu guessed, correctly, that she wanted him to order her to expose herself.

"Move your arms so I can see your body," he smiled at her.

"Yes Master," she replied happily, and slid her arm and hand away from her privates, giving him an adorable little smile as she waved her boobs gently at him.

"Stand up," he told her.

"As you wish, Master," she cooed softly, rising to her feet, and placed her hands behind her back as she twisted her body back in forth in an eager manner.

He approached her, and stroked her stomach, eliciting another cool from her, before sliding his hands up to cup her boobs as he leaned forward to kiss her.

She leaned into him, and kissed him back, moaning as she pressed her breasts into his hands, eager for his touch. He then broke the kiss, and grinned as he continued playing with her tits.

She moaned softly as she loved him enjoying his property. She couldn't wait for him to have her serve him more liberally.
