Sounds great, though he feels like he's forgetting something...

"Would you like me to join you in bed Master?" Mirajane cooed.

Natsu thought about it a moment. That did sound so enticing, but... He had the strangest feeling he was forgetting something...

...

Happy paced around the cottage he and Natsu lived, waiting on him. "What's keeping him?" he asked no one in particular.

...

He shrugged, and decided it probably wasn't that important, and said, "Yeah, definitely."

She beamed and took his hand, leading him to the master bedroom. They both got under the covers, Natsu spooning Mirajane, and placing a hand on her tits from behind.

She cooed, and pressed her back into his chest, and her ass against his crotch, and both drifted off.
