Natsu's way too excited to stop!

"Alright, Lucy, reform your legs!" Natsu ordered in a cheerful tone. "Then lean over the seat! You too, Lisanna, right next to her!"

"You're quite chipper~!" Lucy giggled as she complied, her tail detaching and splitting from the spout of the Lamp, her legs returning, and she and Lisanna bent over, turning their heads to look at each other.

"Of course I am!" Natsu chuckled. "I got two lovely ladies, and just got rid of one of the biggest banes of my existence!" He immediately positioned himself behind Lucy, and after a moment, pressed himself right into her.

"Unh... Glad you're happy Master, and I mean that most sincerely," Lucy crooned as Natsu buried himself to the root, and began fucking Lucy slowly. As Lucy closed her eyes in pure contentment, Natsu reached for Lisanna and began to finger her labia.

Lisanna jolted at the unexpected stimulation, having expected Natsu to just fuck Lucy, then her. So his fingering came as a surprise, but a welcome one. "Oh, unh... Okay..." she moaned, smiling at his actions. She pressed her hips back against his fingers. He then pulled out of Lucy and got behind Lisanna, wasting no time thrusting into her whole using his other hand to finger Lucy.

"Ah... Yes, right there, Master..." Lucy crooned. "Deeper please..." Natsu obliged, thrusting his fingers in to the knuckle, and wriggling them around.

"Like that?" he asked, and Lucy nodded and moaned.

"Yes Master... A little clumsy, but you'll improve," she assured him, before he pulled out of Lisanna, and re-entered Lucy. As he resumed fucking her, fingering Lisanna again, Lisanna turned her head towards Lucy, and leaned forward a bit to kiss her, getting her attention with a peck on the cheek. Lucy turned to return the kiss, moaning into Lisanna's lips.

Natsu kept swapping, and as his pleasure built, he grinned. "Hey girls..." he grunted. They moaned in acknowledgement that they were listening. "Who wants me to cum inside them? I'll give it to whoever begs better..." he panted out, mentally planning to give Lisanna a slight handicap, given Lucy was the Sex Genie.
