Return the previous favor!

"Alright Slut, remember how I licked your cunt earlier?" Erza asked as she used her free hand to finger the zipper over her crotch.

"Mmmnh, yes Mistress," Lucy crooned, giving Erza bedroom eyes, thoroughly enjoying the rough treatment and being called a slut. Erza smirked as she lowered the zipper, exposing her own cunt.

"How about returning the favor then?" she asked, and Lucy nodded as much as she could while her hair was being held. Erza then used Lucy's hair to steer her head down to her crotch.

"Gladly, Mistress! I'm a fucktoy at your disposal!" Lucy grinned, before her face was **** right between Erza's legs. Her tongue came out and began to lick at Erza's folds.

"Mmmnh, good little slut..." Erza moaned, humping Lucy's face. Natsu and Lisanna continued to watch, even as Lisanna took Natsu's cock between her lips. She began to bob her head as Natsu sighed in contentment.

"...damn, maybe I should try acting that dominant towards Lucy from time to time," Natsu mused. Lisanna hummed in amusement around his cock.

Lucy also hummed, though in agreement with Natsu's assessment in addition to amusement, trying to speak said agreement. "Don't talk with your mouth full," Erza chided. Lucy nodded, and slid her tongue into Erza's pussy, and wriggled her tongue around expertly in there, finding all of Erza's sweet spots easily.

Erza cooed happily as she laid down, pulling Lucy's hair more to keep her face plastered against her loins. Lucy naturally gave light resistance to enhance the stimulation, and continued to lick frantically. Before long, Erza bucked her hips in need, and moaned out, "That's it, I'm gonna cum, keep licking, you little sex doll!"

Lucy of course was very turned on by this, and reached a fever pitch with her licking, and Erza gave a loud scream of pleasure, her hips jolting and spasming as her orgasm coursed through her body.

As this happened, Natsu grunted and filled Lisanna's mouth with his seed. She gulped it down, before pulling off as Erza came down from her climax. "...okay, that was quite hot..." Lisanna admitted with a blush. "Though I doubt I am ready to be treated like that..."

"I should hope not, Lucy's a Sex Genie, she has an excuse," Natsu chuckled weakly.
