Twilight and her friends were walking through Ponyville, the train ride had been short but then Canterlot was only a short ride away.

"Yo!" The exclamation caught the princess' attention and she spotted a smiling Vinyl Scratch wandering over. "Not you, Your Highness. I need to speak to Applejack, Rarity, and Rainbow." The mare had her dark glasses on but all three targets felt the gaze of the white unicorn upon them.

"Me, darling? Whatever for?" Rarity nonetheless stepped over, closer to the DJ. "You simply must let me make you an outfit for your next little party."

"Rave, but I need to talk to you three about Sweetie Belle," Vinyl looked to Rarity, "Apple Bloom," then to Applejack, "and Scootaloo." With her look settling on Rainbow Dash, the stand-in mother for the third filly, Vinyl gave a sigh. "We got the seeds out of everypony who wanted them gone, but I insisted on removing them from all the foals, they can always seek out mother once they are older. Your girls saw fit to evade and hide from this."

"Ah don't rightly see a problem with it, it doesn't hurt them does it?" Applejack was unsure as to the problem.

"There is more to it than just… the seed. In your head, you hear music, music that comes from the tree and other ponies who have seeds. It affects and is affected by mood." Vinyl explained it as best she could but couldn't see any revelation on the mare's faces. "Let me put it this way, if two ponies are having a really good time, they tend to broadcast a lot, other ponies tend to hear that and it makes them… excited, too."

Three mares blushed bright red. "Out, out, out!" Rarity clopped a hoof on the ground. "We mustn't subject them to… to that kind of thing."

"But Rarity!" Sweetie Belle's voice came from behind a nearby tree before the little white filly stepped out, her two friends following. "We block all that out with our own songs!"

Rainbow Dash looked at Scootaloo, then blinked. "You got your wings?" There was nothing that could stop the pair immediately zooming up as a wind kicked up, pushing them both higher and faster.

"You block them?" Vinyl was surprised at this revelation from the filly, her eyes narrowed. "How, show me." Sweetie began to sing her song, letting it grow inside, she leaned over to Apple Bloom and shared it with her. To Vinyl it was like the two had simply stopped being part of the network made up of ponies with seeds in them.

"What are you doing?" Rarity looked puzzled, but saw that Vinyl was smiling. "Explain this now, Vinyl Scratch!"

"I don't know exactly how she is doing it, but she is blocking it all out, everything. Sweetie, can you stop a second?" Vinyl reached out a hoof to touch the filly and immediately a song jumped from Sweetie to the DJ. Her awareness diminished down to her normal pony senses and it took a conscious effort to halt it.

"There, like that?" Sweetie Belle looked proud as punch, grinning up at a pony famous all over Equestria for her music.

"Yeah, just like that. Why didn't you just tell me you could block it all out?" Vinyl adjusted her glasses with her magic. "It would have saved this whole conversation!" It was like asking the wind why it blew, or the sun why it shone.

Grinning up, Sweetie shrugged her shoulders. "Didn't think it mattered. Why didn't you tell us you didn't want us to have the seeds because of naughty songs?"

"Seems like this could have been sorted earlier if everypony was a little more open. Just relax girls, we are all on the same side." Applejack put a leg over Vinyl and Sweetie's withers, the latter being much easier. "Now, let's all go discuss this together, like ponies." She gestured with one hoof toward Sugarcube Corner.

Pinkie had stayed in Canterlot, she had a shopping list that had been delivered by Mr. and Mrs. Cake, and she had to get a few things herself. She was trotting along when she saw a sign on a building that instantly got her attention. "House of Happiness? That sounds like the best place ever!"

Trotting over to the door, Pinkie was about to knock when it opened and there was a smiling changeling inside. "Oh, excuse me miss." The drone backed in, holding the door open for Pinkie.

It was still a little surprising to see so many changelings about, Pinkie only knew two with any kind of detail, one was a prince and the other an alicorn! "Thanks!" She beamed in delight, it was such a nice thing to just hold a door for somepony, it gave a sense of the pony finding you important enough to be worth a little of their time. Stepping in through the door, the drone gave a little bow and left the building.

"Good day Ms. Pie." A voice behind Pinkie got her attention and she spun to see a pegasus mare sporting nearly the same color pink as she did!

"Hi there. It said this was a house of happiness?" Pinkie bounced right up to the desk the mare was seated behind. "Do you make ponies happy?"

Cherry smiled a little wider, did she dare assume this pony was naive about what this place was? "We make a lot of ponies very happy. Were you after a little polish for your balloon?" Her dour day was ruined by the other pink mare, Cherry couldn't keep a frown on her face in her presence.

"My balloon?" Pinkie looked confused before a light pink wing extended out and brushed her flank, right where her cutie mark was. "Oh!" Pinkie suddenly put everything together and if she blushed it was hidden by her fur. "This is for that," she put emphasis on the word, "kind of happiness…"

"Yup, but not always what you are thinking. I won't name a name, but one mare comes here just to curl up and let a pony tell her how good a filly she is, not a thing more. We cater to all kinds of ponies, you could say we specialize in strange requests." Cherry finished signing the document before her and slipped it to the out-box.

Pinkie thought on it for a while, she hadn't managed to hook up with any of her usual friends, or any unusual ones, of late. Then a new thought came to her, these sorts of places usually charged. Cherry saw her potential client's face fall and her mane straighten oddly, she raised an eyebrow.

The earth pony sighed. "I don't have any bits on me right now." Pinkie started to turn, feeling all kinds of down now, but a hoof grabbed her tail. "What?"

"Bits are a form of payment. Having the greatest party planner in all of Equestria owe me a party is another." Cherry was, for the first time in her life, able to work on favors. Before, she had to keep the rent up and keep the changelings paid, but now, she was a lot more flexible. "So what is it you would like, Ms. Pie, I am sure we can find somepony who will meet your every need." Cherry smiled at the surprised mare, watching as her mane suddenly sproinged into a curly, fuzzy mess again.

"Oh, oh, oh! I want a stallion, if you have one." Pinkie closed her eyes and thought to her dreams. "No, two. I want the biggest cake you can find… actually, I might be able to cover that. And I want a mare as well."

Cherry pulled out a pad, taking notes. "Might I inquire as to what you have quite obviously planned out?" Slip, Gravel, and Velvet. She scrawled their names down.

"I want to get messy with the cake and the ponies. I want to suck, screw, and lick them all clean!" The moment Pinkie said it, her voice raising in volume, she clapped her hooves over her mouth, then giggled. "Please?"

"My dear, no pony needs to say 'please' here unless they wish to. Everything is given freely." Cherry was smooth with her words by now, scrawling down to get one of the few unicorns on their payroll to visit the room after everypony was worn out. These kinds of messes meant special cleaning.

Pinkie was practically bouncing in place, she had had this dream ever since Gel and Twilight had played with her, when she had been 'fed' her pies in a whole new way. When Cherry got up, Pinkie moved to walk with her as they ventured deeper into the building. "Where are we going?"

"We need to find your new friends, I don't demand ponies hang around waiting, just that they tell me when they are leaving the building… Gravel, have you seen Slip and Velvet?" Cherry spotted one of her prized stallions. Gravel was a changeling who knew full well how perfect he looked, his form rivaling Shining Armor's for 'stallion perfection'.

"Yeah, relaxin' down in room five. Who is this lovely mare?" Gravel looked Pinkie Pie up and down, he knew who she was, but seeing her here titillated the changeling.

"Five will be perfect, you're in on this job too, Gravel." Cherry saw the stallion's eyes light up with delight, Pinkie noticed it too and she realized that the ponies here enjoyed making other ponies happy. It was a revelation that Pinkie couldn't deny, she had found kindred spirits.

"Hi, I'm Pinkie Pie!" She held out a hoof to the stallion who took it and lifted it to his lips, kissing it gently. Pinkie blushed a little at this, it was more a Rarity-kind-of-thing than a Pinkie one, but it made her feel good.

"I am delighted to meet you and must admit, your reputation precedes you." Gravel sipped very lightly and nearly staggered. His eyes were wide at the slightest taste of the pink mare.

"Are you okay Gravel? You look a little… off?" Pinkie closed with him, pulling a stethoscope from her mane and checking him with it.

Gravel leaned on the mare and managed an almost drunk smile. "Just… tasted something a little strong, I am sure my palate will adjust." He sipped lightly again and leaned on her more. "In a moment…"

Pinkie giggled and helped the changeling stagger down the hall until Cherry knocked on a door and opened it without another word. Inside, two changelings were caught in flagrante delicto. She lifted a hoof to her snout to hide her wide grin, they looked cute together.

"Slip, Velvet, we have a job." Cherry smiled in at the pair and the pony… stallion, on top drove faster and faster until he was clearly at his limit and then he pulled out of the mare, leaving her trembling and squirming, clearly lost in a climax he had just brought her to.

Pinkie watched his rock-hard shaft bobbing around under the changeling and she giggled. "Uh, miss Cherry, we are going to need a lot of whipped cream too." Pinkie's eyes were locked on the shaft, even as green fire flowed around the pony.

"Velvet, Ms, Pinkie Pie, she has yourself, Slip, and Gravel on her dance card tonight, she plans to make a proper party of it with cake and, apparently, whipped cream." Cherry gestured to the stallion that had just turned into a mare. "Pinkie, this is Velvet, I am sure you will get along wonderfully."

Velvet was still randy as her stallion form could get and, right in front of her was a mare famous for knowing how to have a good time. "Cake? Cream? Which shall we start with?" Her wide, hungry smile turned into a gasp of shock when the pink earth pony somehow produced a double-tiered chocolate cake and set it down on the dresser. She gasped again when she saw the three little black ponies on top in various contortionist acts with a very full-looking pink pony.

"Me!" Pinkie plucked up some cake and took a bite of it herself before walking around behind the changeling mare and smearing it across her mound. Pressing her tongue against the dark, sweetened lips, Pinkie missed the door closing.

"You indeed, that isn't you getting attention." Gravel advanced on the cake, plucking up a huge amount with his magic, making sure Pinkie could see as he squeezed the dark desert down with his green power and shaped it into a big pony dong! "I take it you like sweet things? Velvet is sweet and sour, you might think it is an odd combination, but I don't mind it."

Pinkie saw the stallion shape the cake so that the dark chocolate looked exactly like a changeling shaft and, when he walked around behind her, she felt as he started to push it in. She moaned into the changeling's depths, her snout pushing cake deeper and seeking out that which she had already pushed in. It was a vicious cycle.

Panting from her release, reclining on the bed, Slip spotted the fun going on. Fire flowed over the changeling and she turned into the stallion she really was. Reaching out for some of the cake, he advanced on Pinkie and pressed the big gob of cake right up and under the pink tail, smearing dark calories all over her plot in the process. "Gonna fill you full of cake and changeling."

Moaning more, Pinkie closed her eyes and stumbled a little as the stallion behind her shoved into her rear while Gravel filled her vagina with magic-wrapped cake. Her prize was lost to her and she lifted her head to see what had happened when the flash of fire caught her attention. Sweetness filled her open mouth as another glob of cake was shoved in, she was about to gulp it down when Velvet reared up and mounted her head.

"Take it." Velvet's voice was deep, like the stallion he had become. He felt as the pink pony wrapped her lips around his shaft and sucked it and the cake in deeper. Not one to deny a mare her needs, Velvet started to buck and hump at Pinkie's snout.

When Sleek ducked her head in, she spotted the three changelings doing quite a number on the pink mare, she opened herself just a touch and inhaled the most amazing mix of love, happiness, bliss, and raw pleasure. She set a big bowl of whipped cream on the dresser beside the half-demolished cake. She spared a glance to see as one of her brethren shoved a cake-dildo deep into the pink pony and released it, he rolled to his back and slipped under Pinkie. She closed the door just as the pink mare lowered herself down, letting the third stallion have her cake-plugged hole.

Oh, I bet by the title you thought I meant they were 'going in' to Canterlot High, woops, no, I meant the cake is all going in to Pinkie!
