There were many situations that older siblings would never want to find themselves in, especially when it came to their younger ones. But today, there were four individuals who found themselves in, perhaps, the number one thing on that list. In the often-used music room of Canterlot High, Rainbow Dash, Rarity, Applejack and Flash Sentry were all sitting together quietly, their expressions those of great discomfort and apprehension. Nobody there actually wanted to be, and that sentiment was as clear as day for all of them. But, here they were, and every once in a while, one of them would let out a long sigh. After some time though, Rainbow, after glancing at the others, cleared her throat and began to stand up from her chair, gaining their attention.

"Ya know...I only recently found out I was Scoot's sister...so maybe it's not really my place to..."

But, unfortunately for her, Flash cast her a dark look, prompting her to sit back down, chuckling nervously as she did so.

"Hehe...right...guess that was never gonna be that easy."

Rubbing his temples, Flash sighed again.

"We all knew this day was coming."

Applejack turned to him.

"Yeah...but now it's here."

Rarity nodded.

"Indeed. They're just so...so...so young."

Flash nodded back.

"I know. But...our parents all think they're old enough. So...here we are."

None of them seemed happy at the prospect, but for now, they just remained silent, slumped into their respective chairs as they waited. However, after a few further minutes of this, their attention was soon drawn to the door of the music room, wherein they heard a knocking upon it. Though they all looked nervous, the four teenagers gave each other looks of understanding, before looking back to the door yet again.

"Come in," Rarity called.

The door opened, and upon the other side were three youngsters, their sisters, Apple Bloom, Sweetie Belle and Scootaloo. The three girls, naturally, were a little uncertain about seeing their older siblings here, but, in they came, closing the door behind them. Gesturing to a set of chairs opposite them, Flash and the others watched as the Crusaders took a spot, getting themselves comfortable before, finally, Apple Bloom broke the silence.

"So...y'all wanted ta talk ta us?"

The four older teens looked to each other again, then, after looking back to the Crusaders, Applejack nodded.

"Yeah...we did."

A silence fell over the group once more, and after almost a full minute of it, Scootaloo frowned.

"So...what did you wanna talk about?"

Raising her hand, Rainbow nervously scratched the back of her head.

"Well...it's kind of a...a hard thing to say."

Instantly, the athlete got herself looks of ire from the other three, prompting her to look at them with confusion.

"What?"

Then, realisation came to her, and her eyes widened with horror, leading to her slapping her hands over her mouth.

"Argh! Right! Bad choice of words!"

Flash slapped his forehead at his half-sister's behaviour, all while the younger girls just continued to look confused.

"Will somebody please just tell us what's going on?!" Sweetie Belle rightly demanded.

Looking to her, Rarity appeared dejected, as she reached forward, and gently placed her hand upon Sweetie's.

"Sweetie...little Sweetie...my precious little sister."

Sweetie raised an eyebrow.

"Rarity...why are you talking like that."

Then, her expression became one of fear.

"Oh no! Is somebody dying?!"

Instantly, Rarity waved her hands in a defensive manner.

"No! No, no, no, no, no!"

She tried to force a smile.

"It's just that...there are certain things that girls your age need to be told. Important things. Things that those in your family..."

She gestured to the rest of them.

"...like us, are responsible for telling you."

The younger girls looked to each other, then back to their elders.

"Like what?" Apple Bloom asked.

Another silence followed those words, but this time, it was Flash who, at the end of it all, decided to get the ball rolling, albeit with very clear reluctance on his part.

"Girls...there comes a time when two people, who care about each other very much...decide that they want to go ahead and...well...do things in their relationship that they haven't done before."

He was met with blank stares of the three girls before him, and after a quick look to his fellow older siblings, none of whom looked like they wanted to add their voice to matters, the lone male continued his explanation.

"And when I say things, I mean...um...physical things."

Hearing that, the Crusaders, to the surprise of the others, developed a look of understanding.

"Oh! I get it now!" Sweetie Belle exclaimed.

Rarity looked to her with confusion.

"You...you do?"

Sweetie nodded, then turned to Scootaloo.

"Yeah! You guys are talking about sex, right?"

As one would expect after an utterance of that nature, all four of the older teens looked to their youngers with absolutely gobsmacked expressions, as though the girls had just said the most shocking thing in the world. The Crusaders, for their part, looked as though they hadn't done anything wrong by saying this, but, after some time of seeing their siblings just blinking slowly, they began to worry a little bit.

"Um...you guys okay?" Scootaloo asked.

Shaking her head, Applejack suddenly looked very concerned.

"Where...what...how did y'all hear about that?!"

Apple Bloom shrugged her shoulders.

"From a book."

Rarity turned to her.

"What book?!"

Here, it was Sweetie Belle who answered.

"Well, it was a few weeks ago. We were studying in the library when we heard somebody laughing.”

Apple Bloom nodded and continued from there.

"We went ta check it out, an' we saw it was Snips an' Snails."

Scootaloo was next.

"They were snickering over some book they had from the library, and when we asked them about it, they freaked and just ran off."

Flash sighed.

"And you read the book afterwards?"

The girls nodded, leaning to the older teens looking to each other. There seemed to be a silent but shared understanding between them, and when they turned their gaze to the Crusaders once more, it was Rainbow who spoke next.

"But...you didn't read all about it...right?"

The Crusaders thought on that for a moment before answering.

"Well...we read about girl and boy parts," Apple Bloom started.

"And what happens when a girl gets pregnant," Sweetie added.

"And stuff like diseases and contra...contra...contra-stuff," Scootaloo finished.

"Contraception," Sweetie corrected.

"Yeah, that," Scootaloo replied.

Hearing all of this, the older teens, rather expectedly, had no idea how to react. They had come in here expecting a very different situation to the one they'd been given. But, after looking at their younger sisters for what seemed like an eternity, they shared a collective sigh.

"Well...ah guess that's that," Applejack remarked.

Rainbow nodded.

"Yeah. Definitely wasn't expecting that."

Applejack looked to them both.

"Guess...guess we weren't really needed."

Though a little put down at that, the girls looked to their respective Crusader.

"And...and you girls are okay with all this stuff you've learned?"

The Crusaders, hearing that, appeared at least a little bit taken aback, but soon recovered, smiling genuinely to their sisters.

"Yep!" Apple Bloom answered.

Sweetie Belle and Scootaloo seemed to share the sentiment, and that, at the very least, was something the other three girls could accept. However, in that silence which followed, Flash slowly got up from his chair, before beginning to make his way over to the music room door, catching Rainbow's attention.

"Where you going, Flash?"

The boy looked to her, his face a completely blank and unresponsive one.

"I am going to do the one thing all big brothers should do when they learn that some boy has accidentally taught their little sister about sex."

He turned the knob of the door, making his way out before closing it behind him. Scootaloo had watched him go, and now looked to Rainbow with concern.

"Aren't you gonna stop him?"

Rainbow, thinking on that, gave her half-sister a smirk.

"Yeah...but not before he's made Snips and Snails wet their pants, Scoots."
