He returns the favor!

"How about you lay back and spread your legs?" Natsu then asked Lisanna.

She blushed but smiled as she did as he asked, parting her thighs to present her snatch to him. "Going to fuck me again, Master?" she asked.

"Not exactly," he grinned, crawling up to her. Her eyes widened as he leaned in, and extended his tongue, licking at her folds.

"Ahn~!" she gasped, jolting at the sensations. "Master Natsu?" she asked. "Isn't this something... oh... subs do for their dominants?" she asked through her moans as Natsu kept licking. But she didn't move away.

Natsu grinned, continuing to pleasure Lisanna, making her writhe. He was actually having fun with it, and quite enjoyed how good he could make her feel. "Enjoying yourself?" he asked rhetorically, before resuming licking her again.

"So much..." she mewled, her hips continuing to squirm as she rapidly approached release. "Please, Master, make me cum!" she begged. Natsu kept going more intensely, and grinned as Lisanna cried out, and her pussy spasmed around his fingers, and she arched her back.

"Unh..." she whimpered, before laying back on the bed, trying to catch her breath. "Thank you... Master..."
