Yes, and Erza returns!

"...okay, Gemini, how about you try mounting me? Lucy, reform your legs, and sit on my face while facing Gemini," Natsu ordered as he laid on his back.

"Yes Master~!" they chimed at once. Immediately, Gemini straddled him, reaching down and guiding his still erect member to just under her pussy. Then, she lowered her hips, and let his manhood split her.

"Unh!" she moaned as her pussy took him to the root, and she rested her hands on his chest. At the same time, Lucy sat on his face, straddling his head with her newly reformed legs. Natsu wasted no time in tilting his head up and licking her folds.

"Oh, yes~!" she cooed, wriggling her hips against his face. His tongue licked at her entrance, and he sighed in pleasure at the taste. "Right there, Master... Lick my pussy more, please~!" she begged. He obliged, working his tongue faster, then harder into the cleft of her womanhood.

"Mmmnh..." he moaned in a muffled manner into her crotch. He reached up and grabbed her hips as she squirmed stop him.

Gemini smirked, moving her hips up and down while gyrating them, drawing out their Master's pleasure, then leaned forward, grabbing Lucy's hands in her own as she planted a kiss on Lucy's lips. "Unh..." Lucy murmured into the list as their hands rose, clasped together as they made out, enjoying the sex.

Natsu's tongue slid all the way into Lucy's entrance, and began to wriggle about in there, making her moan more frantically into the kiss with Gemini. She slid her tongue into Gemini's mouth, dominating the spirit's tongue.

The door was thrown open, and Erza walked in, armored and all, and carrying a basket. "Natsu, Lucy, I caught some food for..." she trailed off as she saw the scene, which paused as everyone turned their heads to look at Erza.
