"What are we gonna do on the bed?" The unicorn filly said happily, as she threw herself on the sheets.

Rarity winced a bit at that. Not only did her little sister have no idea what she planned, she was unaware about... such things in general. Well, she was way too young for it in the first place. She just entered school and the day she got her cutie mark was far away. Of course, she had no idea about that.

Really, though, in a way it was their parents fault, that they were in such a situation. Rarity was barely a mare herself and only recently moved away. What were they thinking, leaving that filly with someone, who still struggled with living by herself? There's so much that could go wrong...

She sighed internally. Of course, that was a load of nonsense. While it was rather irresponsible, there was no way they would have expected her to intentionally do something... wrong with her. And since she was aware of it, there was no excuse for what she was about to do to her sister. The only way to come out clean was to not do anything at all. But...

With a mix of guilt and craving, Rarity looked at her sister. Her small body was lying on it's back on top of the bedsheets, while she looked at her older sister with big eyes, filled with unaware curiosity. A foal's body shouldn't feel like this, but it seemed to become more enticing, the lower Rarity's eyes wandered until they full took in the pink buds of her undeveloped teats and the small slit of her young pussy. It was a sight that cause a tingle in Rarity's own.

As wrong as it was, the mare found it hard, nearly impossible, to resist the little filly who unknowingly presented her sweetest parts to her sister, while laying in her bed. Her naivety even made it naughtier, somehow.

"So?" Sweetie seemed to become impatient. "What will we play?"

Rarity smiled at her. A part of her told her that it was alright. It might be inappropriate, but she wasn't going to do anything really bad to her. Quite the opposite, if everything went as intended, it would even make her feel good. And as long as nopony else learned of this and Sweetie doesn't realize how wrong it was, everything should be alright.

Finally making a move, Rarity went to one end of the bed, where her hind legs were. Looking down at her, Sweetie's smile grew wider in anticipation. The mare smiled back, then went down on her. Lowering her head, she began to flick her tongue over one of the small teats, coating the pink bud with saliva.

Sweetie looked down curiously, unsure what to make of that. "What are you doing?" she asked.

Worried, Rarity stopped and looked up at her. "Does it not feel good?" she replied with a counter question.

"Dunno," the filly just answered. "It feels kinda... odd?"

The mare wasn't sure how to react to that. It was doubtful that the filly would be able to give her a straight answer, if she asked what exactly she felt. Should she continue, hoping that the feeling would become stronger and better? Or should she just go further?

Of course, what she should do is stopping altogether. But by now, that was out of question.

Having made a decision, Rarity moved a bit lower to the slit between the foal's legs. It was strangely cute in it's own way and she smiled warmly as she stared at it.

"Uh... That's a dirty place," Sweetie commented, even more unsure than before.

"No," Rarity replied, shaking her head. "It's beautiful."

"R-Really?" The filly had a hard time believing that the hole she was peeing out of could be anything but dirty.

Instead of answering, Rarity lowered her head again and licked it, from the bottom of the lips, across the slit itself, up to the tiny clit on the top. Sweetie gasped at the unfamiliar sensations that went through her body, as she felt the wet tongue of her sister on her "dirty place".

Again, the mare looked up and asked "Does it feel good?"

"I-I'm not sure..." the filly replied uncertainly. "But I don't think it's bad..."

Rarity gave her a reassuring smile, then went back and continued to lick her fillyhood. She was unsure whether it would work as intended, whether her sister would actually get aroused and pleased by her licking, but soon her soft moans began to fill her ears like sweet music. Reassured by that, she sped up her pace, quickly licking over the nether lips. Meanwhile, she ignored the craving that grew between her own hind legs, concentrating solely on her sister.

"I-It feels good now," Sweetie said, rather unnecessarily, between her moans. "What... is that?"

Rarity didn't answer, as she was too busy pleasuring the filly. It didn't take long until she tasted the sweet juices, that leaked out of the slit. Her little sister seemed to be more developed than she thought. She licked the fluids up, as she moved her tongue over the lips without interruption.

As Sweetie's voice grew louder, Rarity realized that she was close. She sped up a bit more, flicking her tongue over her quickly, giving special attention to her clit. Sure enough, the little body stiffened soon, while Sweetie let out a louder and longer moan. The mare stopped and looked up, watching as her little sister had her first orgasm. The face of the filly was flushed and her eyes closed, as if it was physically exhausting. Rarity smiled, as her body relaxed again and she lay in the bed breathing heavily. Sweetie herself smiled back, when she saw her sister through half-closed eyes.

"That... felt really good," she simply said.

"I'm happy that you liked it," Rarity replied, as she moved closer to her and gave her a kiss.

"But... what was that?" Sweetie asked.

The mare wasn't sure what to say. She could hardly give her "the talk" now. This would only raise more questions. "...I'll explain that when you are older."

"What? We do... that and you can't even say what it is? This makes no sense!"

She was surprisingly sharp for such a small foal. "Don't worry, it won't take too long," Rarity tried to appease her. "And if you are patient, we... can do it more often."

"Really?" Sweetie was happier about it than the mare thought. "Like, tomorrow morning?" And more enthusiastic than she herself was.

"Yes, like tomorrow morning. But now it's time for you to go to sleep."

At the promise to get more of that strange but great feeling, Sweetie had no objections. Rarity stayed with her for a while, having not forgotten her own urges. When the filly finally fell asleep, she moved a hoof between her hind legs, her eyes fixed on her little sister.
