With some coaxing.

"I dunno... I'm not sure I have the nerve to do something like that..." Lisanna blushed.

"You could always wish me to grant you that nerve," Lucy grinned. "I'm sure Master would accommodate such a wish," she told Lisanna, who blushed. "Or, if you're turned on by it, perhaps a compulsion..."

"...Natsu? I wish I was bold enough to do what Lucy did," Lisanna let Lucy's gentle, but persistent goading get to her.

"...I wish for you to grant that wish," Natsu told Lucy after a moment, seeing her expectant look. With a grin, she snapped her fingers. Lisanna jolted, and while blushing, she got under the table, and crawled towards Natsu's cock. Lucy had granted her just enough nerve to go through with this, but not making her so brazen that she would do it without embarrassment.

She grasped his member as it started to get hard again, and began to stroke it tentatively. She grew more confident as she felt him squirm in pleasure, and she leaned down to lick his cock.

"This is so embarrassing... But also very thrilling!" she thought. She ran her tongue along the head of his manhood, and then down the side of his shaft, fondling his balls as she worked.

"...I can't believe you talked her into it," Natsu moaned to Lucy quietly.

"She liked the idea, she just needed a nudge," Lucy giggled. As if to prove her point, Natsu grunted as he felt Lisanna's lips wrap around his tip gingerly, before she began bobbing his head.

Natsu squirmed, unable to believe the turn his life had just taken. He had been sucked off by one girl under the table, and now it was happening again already from another girl.

Lisanna gagged slightly as she took him to the root, but was determined to do a good job, and kept going. She didn't stop until Natsu's cock throbbed, and he released into her mouth, through the amount was less than with Lucy. Understandable, he was about spent.

She pulled off of his member, and swallowed, still blushing heavily, but coming back up with her spoon. "...not a word to Mirajane or Elfman," she hissed to Lucy.

"Like that doesn't go without saying?" Lucy giggled, and Lisanna gave Lucy a flat stare.

"Who told Natsu about my crush on him again?" she asked Lucy in a deadpan.

"...touche," Lucy chuckled sheepishly.
