Erza tries to seduce Natsu as a dominatrix!

"That was a good job, Slut," Erza grinned as she pet Lucy's head. Lucy crooned in delight at her temporary Mistress's touch.

"Mmm, thank you Mistress..." Lucy replied. "I'll do it for you again any time you want, if Master allows..."

"Speaking of your Master..." Erza got up, leaving Lucy still tied up on the floor. She then approached Natsu.

"What's up?" Natsu asked Erza.

"Well, seeing as I'm a switch, I'd like to dominate you a fair amount as well," Erza told Natsu. "We already discussed you wishing to have something of a temporary submissive mode, didn't we?"

Natsu grimaced. "I dunno... Seems like it'd be changing a core part of me... Like I said, dragon pride and all that..."

"Master, there's nothing shameful about acting submissive... Besides, don't you act like a total bitch around Erza whenever she gets mad?" Lucy teased Natsu from where she was on the floor.

Natsu sputtered, and protested, "That's... That's different! At that point, self preservation is a factor!" Lisanna was laughing at this, sitting back up.

"True, but it still counts. At any rate, you don't even need to set pride aside," Lucy sniggered along with Erza. "Like I said, nothing shameful about being submissive to someone else. In fact, it's a point of pride to be able to satisfy your partner, whatever their preferences might be. I should know, I'm a Sex Genie!"

"...okay, but how would it even work?" Natsu asked, and Lucy pondered.

"We could implant a submissive mode in you that swaps you to submissive at say... A code word from Erza, for about an hour? And maybe give you a safe word that shuts if off if she pushes a bit too far?" she added.

Natsu paused, and considered this. It still made him uneasy, but he did still want to keep Erza around as a fuck buddy, and this would go a long way. Trading off the submissive role was only fair if she was a switch...
