Rarity couldn't suppress a blush, as she heard these sounds out of Sweetie Belle's room. They weren't new, she heard them a while back ago. Even the situation was the same. Rarity wanted to check, if her little sister was sleeping. When she heard these sounds that sounded like her voice, she entered her room to see what was going on... and walked in on Sweetie as she was... exploring her body.

In hindsight, she had to admit that she saw it coming. While she told her herself that she had no idea what these sounds are, the truth was that she already guessed that they were moans. These kind of moans. It wasn't that she had no idea what she was doing. She just... kind of wanted to see it. And she never actually regretted it, even if it was awkward for both sisters.

And now that it happened again, Rarity standing in front of Sweetie's room, hearing these lustful moans from within, she... kind of wanted to do it again. But then, she couldn't just walk in again. Not just because it was embarrassing for her, but because it would made Sweetie feel bad. Again. She didn't want a repeat of that.

But she didn't have to, actually. There was another way to sp... check on her, without her noticing it. Although Rarity wasn't quite sure whether she'd manage. It was something she learned long ago, but never really used. And she wasn't a talented mage like Twilight Sparkle.

Still, Rarity decided to try it. She walked a bit along the wall, away from the door, to a spot where she would have a better view. Then, lighting up her horn, she tried to cast this spell.

But nothing happened.

She tried it again a few times, to no avail. Rarity was about to give up and just leave, when, on her last try, the wall seemed to open up and give her a view inside Sweetie's room. She couldn't celebrate the success, though, as the sight shocked her.

Sure enough, Sweetie lay on her bed, moaning in pleasure. But she didn't give it to her herself. Instead, a familiar pony was at her feet, her face buried deep in her crotch. The most startling thing was that it was an adult mare. Fluttershy.

With wide open mouth, Rarity watched as the yellow mare ate Sweetie out. As the initial shock faded, she wondered how she even got in here. But she quickly figured that it was through the window. For a pegasus, that was not a problem at all.

But there was something else, that she couldn't understand. Why? Why was Fluttershy doing something like that to a young foal? Why was Sweetie Belle letting her do it? Why are they together like that in the first place?

And why did Rarity feel so envious? Of who, actually?

Simple as it was, Rarity couldn't understand the scene in front of her. However, it was actually her feelings that confused her. She wanted to swap places with both of them. She wanted to feel Fluttershy's tongue moving over the swollen lips of her pussy. At the same time, she wanted to bury her face into Sweetie, sticking her tongue into her and tasting her juices.

Rarity moaned. She didn't even notice how one of her front hooves moved between her hind legs. Not that she minded. It was like any resistance broke down and she refused to deny how much seeing them like that turned her on. Longingly she watched as Fluttershy's tongue moved along Sweetie's small slit, while she listened to the moans of the filly. The lips of the pegasus mare were smeared with juices, as if she just greedily dove in.

Being quite into it for a while, it didn't take long until Sweetie reached her limit. Her body seemed to convulse as the final pleasure overtook her. Fluttershy looked up from her pussy and smiled at the sight of the orgasming filly. Afterward she moved up and kissed her on the lips.

As the two began to cuddle, Rarity dropped the spell, standing in front of a solid wall again. She also stopped masturbating. For now.

She probably shouldn't actually do this, but Rarity felt that she should give the two privacy. Still, she couldn't entirely approve. Not so much because she felt that it was wrong, but because of her envious feelings, which she still didn't quite understand.

Rarity went to bed. There was a lot to think about. Not to mention that she had to get rid of her horniness. She wasn't quite sure what to make of this whole thing. Either way she would have to talk with Sweetie Belle and Fluttershy. Rarity sighed. It would probably be uncomfortable and unpleasant.

But it could be the start of something interesting...
