Pairing: Heavily Implied!Reborn/Lambo

Author's Note: I know Nana is usually a pretty calm person. But the thought of her getting mad at the guy who ruined her- practically adopted by this point -son's innocence really amused me. Thus, this was born. It's short, but I still like it.

Summary: On Reborn's birthday Nana sees the one thing that could send her into a rage. A 25-year-old Lambo who, very obviously, isn't the innocent young boy she once knew.

It had been an accident. Nana had walked into the living room in order to present Reborn with his birthday cake. The moment she had, Lambo had caught sight of the cake. After running to get to it he had tripped. A large, pink bazooka had abruptly fallen out of his afro, flown into a wall, and bounced back, engulfing the surprised cow-child.

"Lambo!" Nana cried in horror. Before she could even think about putting down the cake to help the young boy, however, the bazooka began to spark.

"Oh no! It's malfunctioning!" Tsuna cried. He attempted to stand up, only to lose his balance and fall into the arms of one of his friends. A boy that Nana couldn't remember the name of at the moment as she was too busy coughing and waving away the clouds of pink smoke that were suddenly in the room.

"L-Lambo?" Kyoko was the first one to say something. And she sounded confused and disbelieving. Nana opened her eyes. And paled at the sight of the man that had ended up in the young child's place. The man looked up at her from his place on the floor, his expression confused yet somehow oddly detached.

"Mama?" His voice was deep, but the look in the one green eye that was open, told her all that she needed to know.

"Lu-Lambo? Is...Is that you? Is that really you sweetie?" She asked, knowing she had to make sure. The man smiled.

"It's good to see you again, Mama."

"..."

"Mama?" For the first time in her life, Nana cursed.

"WHAT IN THE SEVEN HELLS ARE YOU WEARING!?" The- obviously adult -Lambo looked down at his outfit and studied it, a blank expression on his face. Just like child Lambo's pajamas, it was cow print. A frilly maid's dress with an EXTREMELY short skirt, one that BARELY covered HALF the man's- admittedly shapely -THIGHS.

"A maid's outfit." He replied finally, looking up at her once again.

"But...But why?" She asked. What could possibly have happened to warrant her precious Lambo wearing such provocative clothing? Not to mention-

"Are your hands tied behind your back?"

"Yeah."

"But WHY!?"

"It's part of the game." Nana blinked, staring at Lambo with an expression that, quite frankly, mirrored the one that had been on the man's face most of the time he had been there.

"Gu-Game?" Lambo nodded.

"Yes. I'm supposed to be the reluctant maid who has been presented as a present for his master's birthday." It didn't take long for Nana to put two and two together. Although everyone else in the room still seemed confused, Nana got it. Nana, and the birthday boy in question, who had surreptitiously been edging his way out of the room as the atmosphere got steadily darker and more tense. Suddenly, the adult Lambo disappeared, and a confused child!Lambo had taken his place.

"Mama?" The young boy asked, looking up at her with wide, trusting, INNOCENT eyes.

"Yes, Lambo-san?"

"What's sex?" Realization dawned on the others' faces after the question had been asked.

"REBOOOOOORN!" Nana's furious howl subsequently caused an immense earthquake felt even all the way over in Italy.
