Pinkie Pie Seduces a Shoggoth.

The people of Ponyville stared agape at the horror at the edge of their quaint little town. Stretched out before them was a horrible fleshy beast roughly the size of a bus. Nopony could quite define the beast as appendages and sensory organs bubbled in and out of its central mass as it saw fit. In fact the ponies were so confused and horrified that none of them seemed to notice as it consumed Pip and Scootaloo whole and alive and added them to its already tremendous bulk.

"Stand back everypony," came a shout as the elements of harmony excluding pinkie, who was probably out doing some manor of horribly destructive shenanigans, cut their way through the crowd. "We'll handle this," continued Twilight. Twilight charged up the magic in her horn as she readied to blow the newest unspeakable horror to bits.

"Wait!" Pinkie shouted as she threw herself in front of the monster just in time to stop her friend. "Twilight, this is a shoggoth. You can't just blow it up."

"Well, why not," whined Twilight.

"Because, if blow you it up you'll just end up with thousands of little shoggoths." Explained Pinkie. "The only way to deal with a shoggoth is to talk to it." Then Pinkie pulled a tuba from seemingly no and began playing a tune. To the shock of everypony a long snout grew from the front of the shoggoth and played a song to match pinkie's.

After a tremendous and, at least for pinkie, physically exhausting jam session with the shoggoth, most of the crowd had dispersed. Now, only the elements of harmony and Ponyville's most enthusiastic fans of brass bands remained. Finally, Pinkie and the shoggoth went quite. "Ponies of Ponyville," Pinkie announced, "Dave and I have reached an agreement. He shall stay in Ponyville and seek gameful employment."

"But how do we know it won't try to kill us the second we turn our backs," said Rainbowdash, eyeing Dave the shoggoth suspiciously.

"I'm sorry Hon," said Applejack, quickly drawing her friend's attention, "I don't think we have that choice."

"Well I for one welcome this new being to ponyville," said Rarity, extending a hoof for Dave to shake. He extend one of his fleshy arms and politely shook her hoof, leaving behind a great deal of sticky residue.

"Well then," Twilight spoke up, as Rarity wiped the residue off of her hoof on Fluttershy's coat, "without further adieu, by the power vested in me as a princess of the realm, i deem Dave the shoggoth an official citizen of Ponyville."

With that, the last vestiges of the crowd went back to their business and Dave was left alone to seek out a suitable drainpipe to live in, but as he started to go he heard Pinkie say, "You can stay with me for awhile, Dave." Ever since his escape from bondage, Dave had found the idea of living in a building unsavoury at best, but for some reason he found something about this pony to alluring to pass up the offer.

"You just sit tight I need to use the little filly's room," Pinkie told Dave after she had led him up to the giant cupcake art the top of Sugarcube Corner. Dave felt a little unnerved when Pinkie cast a sultry glance at him as she left the room, but he was sure it was only his imagination.

Dave was unsure of what to do while he waited for Pinkie to finish her business, but luckily for him, he didn't have to wait very long. He reeled slightly as he saw Pinkie emerge from the bathroom in lacy black lingerie. Subconsciously, he created several new eyes, but quickly averted them because he was a gentleshoggoth, after all. "Like what you see," said Pinkie, "I hope you're ready for your private welcome party. In his arousal, Dave couldn't stop himself as many butts grew on random locations on his body. "Oh, I see your already ready to go." Pinkie said and then kissed the closest thing that Dave had to a mouth. Which was one of his new ultra sexy butts.

Pinkie Pie was very knowledgeable when it came to shoggoths, but even she was shocked when Dave's many butt-cheeks grew nipples and began to drop half and half. However, Pinkie was not a mare to shy from an opportunity, so she suckled from his eldritch butt tities until she had to come up for air. "That's some quality shit right there." She gasped for breath, and shoved her hoof into the nearest of Dave's butt holes, but she found that something else occupied that space. Suddenly, from all of Dave's abuses erupted long penises tipped with hexagonal prisms rather than the rounded heads most ponies were used to, but Pinkie was a connoisseur of shoggoths and therefore knew that a hexagonal was far superior to a normal one.

Pinkie was already wet, so climbing onto Dave's gargantuan shoggoth coco and sliding it into her pink pony pussy was easy. But what neither Dave nor Pinkie knew was that, because her husband was away, miss cake had been listening to Pinkie and Dave the entire time and when on of his dicks came down through the ceiling, she had taken her chance. She stretched the shoggoth member down enough that she could funnel it into her hot milf pussy.

But that didn't matter to Pinkie and Dave because they were having the night of their lives. Pinkie had shoved all of Dave's shoggoth beef into any holes that she could find, and when she ran out of holes on her body she shoved them into electrical sockets and lighting fixtures. Even for a shoggoth, this was unbelievably painful, but Dave didn't care, he wanted his shoggoth shlongers shocked till he came volumes. Pinkie had effectively pinned herself with the absurd number of dicks in the room, but the electric shocks that reached her through Dave caused her muscles to spasm and convulse in a way that got Dave off.

It wasn't long before Dave's penises began to violently twitch and leak dry cane sugar. The sugar mixed with Pinkie's marecum and the resulting concoction formed into small gelatinous creatures and slink away into the cracks in the walls. Finally, Dave shot out a great wave of sugarcum, and with it came the remainder of what had once been Scootaloo and Pip, now fused together into a horrible gooey monster with the head and legs of a pony and the body of a sea turtle with urchin spines growing from its back.

That monster as born into the world from Dave's nurturing inwards and began to frantically hunt for a new host, so it quickly tore Pinkie's vagina to shreds and started to break her pelvis in an attempt to enter and attach to her uterus. Dave just watched because shoggoths find that super hot.

Finally, Pinkie managed to pull the Scootaloo monster out of her cervix and throw it across the room, where it scurried away most likely to die pathetically and stink up Sugarcube Corner for the next few months. Pinkie laid on her back and as the sugar, blood, marecum jellyfish leaked out of her, she said in a breathy voice, "best... shoggoth... ever."
