Happy's return says yes!

Before Natsu and the two girls could discuss anything further, the door opened, and Happy walked in with a small basket with a couple of fish. "I had some luck, but not as much as I would have liked," he was pouting, before looking up. "...you guys are still going?"

"Uh, yeah," Lisanna blushed heavily, covering her body.

"Don't worry about it, he's a cat, your body does nothing for him," Natsu chuckled.

"Well, I'm part cat at the moment!" she pointed out. Natsu paused, not having considered that.

Happy waved her off as he headed for the ice box to store his fish. "Yeah, but from what I understand, the parts that matter are still human. Your ears are cute though," he assured her.

"...oh," she replied, relaxing.

Natsu chuckled. "Guess that's the end of the fun for tonight..."

"Awww," Lucy pouted, her lip quivering. "Does it have to end?"

"Do you want the awkwardness of sex while Happy is around?" Natsu asked her, raising an eyebrow.

"No thank you!" Lisanna immediately agreed with him.

"I second that!" Happy agreed with a snigger.

"You better not make a habit of interrupting our fun," Lucy huffed, crossing her arms as she stared at Happy. "Else I'll personally see if Erza's record for how far you can be sent flying can be broken."

"...A-aye!" Happy yelped. Natsu laughed a bit at the half joking threat, and they headed for the bed, Happy agreeing to sleep on a pillow on the floor so Natsu could share the bed with his lovers. They were soon peacefully asleep.
