Octavia opened up a small package in her staging room. It’d been left by Sweetie Belle apparently, a final piece to her dress from Rarity that she was showcasing tonight. And… yeah, it looked like it did belong with her dress. Then again, a Treble Clef brooch could really go with any of her things she thought as she pinned it over her breast.

She then grabbed her bow and left the room. The show was in only a few minutes, and she needed to get on stage. It was an important one too. It wasn’t a big show, but the few ponies that would be there were influential in the music world, so she would need to play her best. Show them the sort of musician she wished to be known as.

That was part of why she had commissioned a new dress from Rarity. It was simple and elegant, hugging her body with its black, satin cloth. It was cut to the hip, which was a more provocative look, but the simplicity of it was akin to normal classical musicians. After all, Vinyl had affected her music by being her roommate, so it was always classical with a touch of modern flair.

‘Now if only I’d ever thought of a way to add sex to it.’ The thought made Octavia smirk as she dismissed it. It was silly of course, as a cello was rather hard to make sex anthems on. You wanted louder base, like the sort that Vinyl played, especially at the topless clubs she went to. Octavia’s music wasn’t really for places like that.

No, they were meant to be more sophisticated, she thought as she stepped onto the stage. The curtains were closed still, with it being dark still back here. She could see her cello, along with a silhouetted figure standing next to it. She couldn’t make out much about the pony, except that whoever the mare was, she had a rather impressive figure, as she could tell even like this that she must have giant breasts, along with huge thighs, much larger than even Octavia’s!

And… it was Sweetie Belle, wearing a loose fitting robe. The eighteen year old mare didn’t hide anything with it, but how could she? Her nipples were large and erect, dripping with white milk as they bounced on her chest. Her chest swayed with her movements, something that happened when they made up maybe a quarter of her total mass.

And for Octavia, seeing another mare like this, it made her whole body heat up. Her tongue pulled itself out of her mouth for a moment, wanting to coil around those breasts. Her free hand gripped the air, wanting at those soft flanks, and… and…

She swallowed hard as she took a step back. “S-Sweetie, what are you doing here?”

Sweetie stepped forward, reaching up and grabbing between Octavia’s legs. The musical mare jumped at the sudden touch, but it wasn’t for the reason she thought it should be. It was because of how good it was. How much she needed the hand there, and she barely stifled her moan as Sweetie’s breasts pressed against Octavia’s.

“I got told by a good friend of mine how much you loved mares, and I couldn’t think of a better way to come out to the world than with another wonderful mare that the whole world should know. So, I came to help. You don’t mind, right?”

Octavia couldn’t speak as her body lit up like a candle from Sweetie’s aggressive hand. It only became worse as Sweetie grabbed her breast. They’d always been sensitive, but now… now she thought she might cum from just this. Did she really need a mare this badly? Sure, she’d been with ponies before, but never a mare. Not even when she caught Vinyl coming out of the shower, water glistening on her smooth body. Her small breasts being perky in the light…

Octavia leaned in, sucking on Sweetie’s neck to stifle her next moan. She… She had a minute. She would get off, and then Sweetie would go. Yeah… Yeah, that would work. That would make it better. She just needed her fill.

Octavia’s hands went up onto Sweetie’s breasts squeezing the gargantuan mounds as she sucked harder onto the other mare. They were so soft, and the whore’s milk slathered itself onto her hands. Would the milk show up on her dress? Would the crowd be able to smell her ecstasy? Would a mare in the crowd get aroused by it?

Sweetie could feel Octavia shake, so she reached up, letting the poor mare’s drenched cunt go as she grabbed one strap of Octavia’s dress, and then the other. The black satin fell off, before it transformed. Sweetie then pushed Octavia away, just as Discord let the curtain part.

Octavia looked to the crowd, blinking through her confusion. She was… she was supposed to be playing, but her body only wanted to keep playing with a mare. Any mare. It just… needed more. Needed more than her repressed self had allowed it.

Her thighs shook as she began to move, and she looked down as she went to grab the bow she’d dropped. And… and what she saw was amazing.

Her body had transformed to be similar to Sweetie’s, though as she wasn’t fully committed, her breasts were still manageable and without the constant leaks that Sweetie had. However, her dress had changed into lingerie that would make Vinyl blush.

First, over her breasts, was a triangle of black silk. Well, a triangle made of strings, so it covered literally nothing, but did hold them up, forcing them to bounce and squish together much higher than Sweetie’s free hanging set.

As for her panties, they were two sets of strings that outlined her dripping pussy. Nothing was hidden like this. In fact, bent over like this, she knew her pink folds and tight ass were on complete display. She… She should just get off stage. There was no way she could perform like this.

And then, Sweetie Belle began to sing. She didn’t just sing though. She danced while she sung, her robe falling away so that while she moved, the audience could see every part of her as it moved and dripped. And, of course, the whore didn’t keep it graceful, adding many movements that looked all too fun, such as bending over on one hoof, all while two of her fingers slammed into the cunt she was showing off to the crowd.

Looking to the crowd, in Octavia’s eyes, their shocked expressions meant they liked it. No, not liked. Loved it. That they wanted this sort of performance. That she could play with herself while she played.

And so, she put one hoof on the top of her cello, showing them all how flexible she was, and played her entire set with her bow grinding right between her slit.

It wouldn’t be until the after party that the two musical sluts would get fucked, but the paper in the magazines showed them with their audiences ‘applause’ coating every inch of them while they smiled at the camera, the quote being, “We hope that all of Equestria will see our shows soon, and we’re looking for stallions to join us immediately for our shows.”

Sorry these took so long to come out. They were done WEEKS ago, but things came up that had this fall to the side.
