"An unexpected private party with Pinkie" or "Pinkie parties harder than ever before"

The prince had been preparing for weeks and weeks his section of the entire palace had been completely redorated in hopes of a huge turn out, but sadly no one had came, unknowing to him all of his letters had been accidentally dropped in a sewer and lost forever, so he decided to fly to the little town of Ponyville hoping to find somepony to come to his magnificent party.
He looked all around the town, but it seemed everypony he had turned to was very busy, but this didn't dishearten him, no, he continued to search the town hoping at least a single pony would come to his party.
Meanwhile, at the sugar cube, Pinkie was bored. She had just finished 3 parties over 3 days, all for her pet crocodile Gummi. She wanted to hold an after after after birthday party but all of her friends said no.
The prince spotted an odd little place and decided he'd try it, he trotted up to the doorway and knocked, not exactly knowing what to think of it, "hello? Is anypony home?"
Pinkie walked to the window. "If I can't start a party, perhaps I can join somepony else's!" So she headed out, Gummi sitting in her hair, whilst she searched for the best party ever!
Just as the prince finished his sentence, the door flung open, nearly smacking him in the face. He was about to yell in protest, before noticing who was responsible for the rude shock. A pink little mare bouncing out, wearing a party hat-no, a crocodile wearing a party hat on her head.
The prince eyed the pretty pink mare, he was at least double her size, and he immediately took a bit of a liking to the way she was so abrupt with doors, "oh, pardon me miss, I am Prince Molester, and I came here hoping to invite you to a little party of mine," he said looking the mare up and down then spied gummy on her head wearing a party hat, "it would seem you are already prepared for one, am I interupting something, miss?"
"Not at all! I was actually looking for a party to go to! I'm Pinkie Pie!" Pinkie exclaims in her usual over-excited way. At the same time, she shakes hooves rather violently with Prince Molester, slightly startling him. "So tell me more about this party of yours? I assume someone like you would have a ton of guests already!"
"Its wonderful to meet you miss Pinkie! And, well uh no, actually I was looking for somepony to come to a big party I was to throw, but sadly nopony came, and it seems nopony wants to at all," he sighed slightly and then perked up realizing she had pretty much said ok to coming to his party, "You, would like to come?"
"Well of course silly," Pinkie giggled. But truthfully she was both excited and sorry for the prince. She would have to do something about that. "I have lots of friends, perhaps I could invite some for you! Cool huh?" Pinkie says as she nudges Prince Molester
He looked the mare over once more then smiled, "No no, I think, you'd do, you're quite the pretty little mare, and I'm certain you're the life of the party even if its only a party for two~"
Pinkie felt unusual. She had never experienced a party for two, especially as she always invited everyone. She looked at the prince with one eyebrow raised, and said "Party for two..." before realising he had noticed her talent for being the life of the party, then finally she said "Okie dokie loki! This should be fun!"
He nearly squeed, finally finding someone to come to his party, even if it may have been a different kind of party, which actually made him Even happier, he quickly wrapped his hooves around her and enveloped them in magic, teleporting them to the palace ball room which was completely empty, save for the party decorations which seemed to litter the room
Pinkie had been caught off guard by that teleport. She now knew what twilight feels when she teleports. After shaking of the dizzy spell of that teleportation, she takes in the sight of the ball room, full of decorations, which appeared, to her at least, to be put up in a rush. "Nice place!" she said, still feeling somewhat dizzy from the teleportation. "So where shall we start?" Pinkie was trying hard to ignore the second-rate quality of the decorations, before remembering about Gummi. Gummi was not on her head!
Gummi was pleased with himself. He had managed to escape from Pinkie Pie by hiding under a nearby streamer when Prince Molester had teleported them. As long as he stayed there, and Prince Molester kept her distracted, Gummi could have all the party snacks he wanted. Of course, being a baby crocodile, he didn't realise the fatal flaw in that plan, which involved getting to the snacks.
"I think gummy may have escaped your head and stayed behind miss Pinkie, don't worry, he'll be fine," he smiled reassuringly then hugged her a little tighter before letting her go, "Well, I have games and food, and all kinds of things to do, and even a super special game we could play if you wanted to~"
Pinkie looked into the prince's eyes, and thought about this special game. "Special game?" she asked... whilst grabbing a glass of punch. She knocked a chip or two onto the floor, which Gummi proceeded to snap up
"Mmhm, a very special game miss pinkie~ it may require us to be, in a more comfortable area though" he said and winked at her
Pinkie remembered this line. Cherilee had told her about how Big Mac used the same line on her. Oddly enough, Pinkie felt this was a perfect opportunity to learn a new lesson in friendship, and perhaps she could get spike to send a letter about it to the princess. "I see where your going with this." she said. After a short pause, Pinkie immediately said "Let's do it."
Her reaction actually caused him to blush a little, as he had thought there would've been more of a chase, but he certainly liked her abruptness and he smiled, "certainly, where is good for you? My bed is the biggest in all Equestria, but right here is good for me too, actually~"
Before he could continue, Pinkie had already leapt towards him. "Let's just do it now!"
He pulled the mare into a hug and fell on to his back, the mare was on his stomach and he pushed his hips up, poking his member at her marehood, "Right now?~" he smiled
Pinkie went straight for it, like a cat after catnip, only less violently. She let his horsecock go straight into her, before she realised how big it was. She was so surprised and aroused by its size, that the only sound she could make to respond to the prince was a soft moan, but that was all that was needed.
The prince was getting used to her abruptness and began to slowly pump into the mare, his dick being quite snug in the little mare made it a bit hard to pump.
Just then, Princess Cadence walked into the room. She didn't notice the two ponies doing it on the floor, as she was concerned about the time, ensuring that her distant cousin Prince Molester was done with his booking, then onto the little crocodile munching away at the tons of snacks left over. Suddenly, she notices Pinkie and Molester doing it in the middle of the room. She is so disgusted she nearly faints.
Pinkie hadn't noticed the princess. In all truthfulness, all she could notice was the giant semi-flaccid dick of the Prince. She could feel her whole body shuddering as the huge log inside her grew longer, harder, and started to move.
The feeling of her tight hole around his dick was exhilarating, he began to pick up the pace slamming into her harder, pulling out faster. He was fully aware of Cadence's presence, but simply did not care if there was an audience.
Pinkie had by now lost all sensation in her hooves. She had still not noticed Cadence, as she was facing the wrong way. She went limp about 5 minutes in.
Cadence leaves in a gallop to tell Princess Celestia. Hopefully she would send the two of them to the moon... Cadence storms into the throne room, to notice her husband, Shining Armor, eating some hay. Satisfied with that much, she runs over in tears to explain what she has been unable to unsee.
He continued to pump hard into the mare, not quite realizing she had gone limp, he just kept pumping his stallionhood harder and harder into her, his muscles tightened ever so lightly at this point
Pinkie's vision was failing her. She had never had sex with a allicorn before, and at this rate she just wants it to stop, but it wouldn't stop. She faints rather quickly... Head going straight past the prince's right hoof.
Shining Armour looked at his wife. She was clearly distraught
"Honey, what's wrong?"
"I-It's Prince... *sob* Molester..,"
"Surely it's not just him..."
"I-Its also P-Pinkie Pie..."
"You mean twily's friend?"
Cadence merely nods, crying slightly more
"What are they doing?!?"
Cadence looks away...
"Honey, tell me..."
"They are having... *sob* sex in the... *sob*... ball room..."
"Honey don't worry... We are heading to the crystal empire tomorrow. We can leave him behind..."
Meanwhile, Molester continued to have his way with the mare, pumping even harder now, his cock throbbed inside her, he'd soon cum, but he wasn't quite certain whether or not he could do so inside, but was quickly making up his mind.
Pinkie began to stir... She had recovered from the orgasm she experienced, and it was beginning to become pain...
He realized she was waking up, and soon it wouldn't be any fun for her, so he thought he'd give her a rather rude awakening, he pumped harder and harder, his member throbbed more and more, finally, he slammed inside one final time, lodging the full length inside her and exploded with cum
The pain hit its peak. Pinkie woke up all of a sudden and gave a bit of a squeal. For about half a minute there was a still silence, in which a cartoon checklist went through Pinkies head.
He kept his member firmly planted in the mare and panted slightly, wondering why Pinkie hadn't said anything about him cumming inside her, or complain to him about being so rough
Suddenly, Pinkie gets up, a little shaken. She fails to hide her confusion and mumbles, "What just happened?"
"Well, uh, pinkie," he stammered a little at her questioning what had happened after being so quick to jump straight to it, "it would seem you've had sex with me~"
"But... I mean... I know that much... Uhh..." Pinkie stutters, clearly dazed and confused by the fact she had fallen unconscious from the excitement and pain.
Gummi was still munching away at chips, paying no attention to what had just happened.
He smiled at the mare, she was seeming even cuter now and he almost felt a little bad that she had passed out and he had just continued to have sex with the mare, but shrugged it off as she had been quicker to jump the gun than he did, "Something the matter, miss Pinkie?"
Pinkie struggled to remember. She must have fallen unconscious or something. That was probably it. "No, nothing wrong." She was wondering where to go from here, and her face showed this clearly.
He noticed the mare's pink face turning a bright shade of red, and took this as a little bit of initiative to try and see if Pinkie would like to continue their little party, "Um, miss Pinkie, would you like to continue this in my bedroom, I think it'd be much better if we did this somewhere more... private, so we don't have anypony interrupting us, and all," he smiled
Pinkie thought about this. Then she remembered the pain of the Prince's large cock, and said "Perhaps another day, today really hurt... But it was fun!" Pinkie smiled.
"Aw, if you really must be going, Pinkie..." he pouted a little, "I'll gladly take you back home."
Pinkie realized this meant a teleportation back. Suddenly, she remembered Gummi. She looked around and saw him, hiding behind some snacks. In a flash, she grabs Gummi and returns to the same spot. "Okie dokie lokie!"
He pulled Pinkie into a hug and enveloped them in his magic, landing right in front of sugarcube corner as they had left it, "That was quite the party miss Pinkie, perhaps you'd come to another party of mine sometime?~" he said as gave the mare's cheek a kiss, and then released her from his hugging.
Pinkie released a breath of stale air. She would have to get twilight to help her with withstanding teleportation...
"Sure. When's the next party? Perhaps I can bring a..." Pinkie giggled. "... A friend?"
"Why, yes of course miss Pinkie, that sounds like it'd be quite the party~" he said then thought for a moment, "and I'm not sure when the next party would be... sometime soon, though, definitely."
"Okie dokie then! See you next time!" Pinkie said... And went back inside.
"Be seeing you then pinkie!" He teleported back home to clean up the decorations, and a little pool of liquids on the floor, and then try to convince Cadence she had been dreaming or something... He certainly couldn't wait for the next party, and hoped pinkies friend would be as willing to party as hard as she had.
