Walking into the master bedroom that is Sunset's room, Trixie walking with Sue found the others already waiting for them. The bedroom is a classroom that's been converted to be Sunset's man cave. The room is dominated by a king sized bed, which could have been bigger but the amount of fluids that spills on the mattress would make cleaning larger beds a big chore. The cleaning is done by hosing the mattress down and left outside to dry.

Sue's daughters Suni and Mina are already in the room playing with Sunset's X-box on an online game. Sunset is with Adagio, Aria, and Sonata who are preparing for the ponying up ritual. Which is them just going to sing while Sunset plays his guitar and see if they can't pony up.

"We're ready when you are," Aria said to Trixie.

"I just sing?" Trixie asked.

"Yep! You guys just stand there and let us play our music," Sunset said.

Trixie nodded and walk over to the Dazzlings who are already undressing out of their clothes like Trixie is doing as if it fails, they're still going to have sex. Sue and her daughters Suni and Mina also undress, showing off their slender and busty bodies. Both Suni and Mina have slender bodies with large breasts, while their mother Sue is a total milf with huge breasts, wide hips and large butt.

Trixie and the Dazzlings all began humming to get into tune as Sunset began playing his guitar. He started out slow, trying to warm everyone up, before he picked things up. His fingers danced across the strings and the four girls began to sing along. Sunset sang about the world being full of colors and how it should be preserved at all costs. A song that would later become known as "The Rainbow Song". It was something that Sunset wrote before he left the Rainbooms behind.

The song and the girls singing had the desire effect as they all glowed with magical energy. They were so happy singing together and playing their instrument. Sunset and the girls harmonized very well, showing how close they have all become. Allowing them to pony up, growing bigger and taller as pony tails and ears pop out or replaced their human ears. (1)

The Dazzlings all gain translucent wings and fin like ears, showing their dragon features off. They also gain bigger and fuller bodies with all of them now standing at over 9 feet tall. Sonata who has the biggest breasts before, are now massive even on her bigger body frame. Aria now has an even more massive jiggling butt with a more muscular built. And Adagio now has even bigger breasts and a butt pack with plenty of meat, that are well balance between the two, giving her an hourglass figure right between her two sisters pairs.

Trixie looks over herself and found that she now stands at 7 feet tall and has increased in both her breasts and butt size. Nowhere near the Dazzlings levels, but breasts are now E cups and her butt has gotten bigger, giving her a slender and busty built. Trixie felt so much stronger and feeling her forehead and checking a mirror she sees that she has one of those gems that Rarity and Twilight gain when they pony up, making her a unicorn. She turns and stares at Sunset's naked pony up form.

Sunset already a stud became an alicorn stud massive wings on his back, a muscular body that stand over 9 feet tall. Looking down Trixie saw that his 18 inch cock has grown to be 26 inches long and 4 inches thick. And below that are two massive melon sized balls, twitching with excitement as it's ready to unload its viral seeds in the wombs of the 7 women in the room. Sunset has become the stud that he was born to be.

"If you think that's impressive you should see what he be like as a full pony," Aria said to Trixie.

"He be bigger?" Trixie asks shaking with both fear and lust at the sight of Sunset's naked body.

"Yes," Adagio said as she pushes Sunset onto the bed and got on top of him in a 69 position and began sucking and licking of Sunset's massive cock, and Sunset large hands grabbed her big and soft butt cheeks squeezing them as he licks her cunt.

Trixie and the others joined in on the massive cock in front of them. Trixie went to work on licking and sucking Sunset's balls while Aria and Sonata joined their sister in covering Sunset's cock with their spit. Sue, Suni, and Mina stretched their necks allowing them to lick and suck on the shared cock as well.

Sue nudged the others away and push Suni to straddled Sunset's hips taking control, supporting herself on his washboard abs. Adagio relinquished his twitching knobhead with a final tug and guided the monster tip to the entrance of Sunni's quivering cunt. Slowly, Suni impaled herself on his cock head until the entire head was inside her pussy. She groaned in pleasure, relishing in the sensation of his pulsing rod filling her so completely. Still, she had only taken a few inches of his improved 26 inch staff and Sunset eagerly waited for her hips to push down so that he could feel more of his manhood being enveloped by her warm innards.

Sue push Adagio off of Sunset's face and replace her and as she watches her daughter Suni work the giant cock into her cunt, she's having her juicy cunt eaten out by their shared lover. She looks on proudly as Suni takes the massive cock of Sunset, working it into her cunt. Mina is watching with lust as she waits her turn with Sunset, like the others who are watching and waiting as it's their family's turn with Sunset today and they get to go first.

Suni panted as she slid a couple more inches of my shaft inside her overfilled pussy. The other women watched intently as over half of Sunset's giant cock somehow managed to find its way into the depths of Suni's vagina. Finally, he felt his tip hit the back of her pussy. Sunset always treated his women as a lover never going too rough, and never trying to push all of his cock into them.

The several inches that couldn't be fit into Suni's cunt allowed Trixie and the others to continue to lick the remaining inches of his shaft left outside. Join by Suni as she's one of the few monster girl races beside Nikki and her daughters Kolla, Ellen, and Rhonda, who are Nukekubis who can detach their heads and their heads can fly around. Stretching her neck around she licks and sucks on Sunset's balls trying to speed things up so he can cum into her womb. Sunset is a love machine and takes awhile to cum, and now that he's now a pony, his stamina and endurance would be much greater and be able to go on for hours before cumming.

Aria and Adagio decided to use their free hands to rub Suni's mound vigorously. The combination of Sunset's oversized prick plowing her cunt and the two sirens expert caresses brought Suni's over the edge. She exploded in a guttural orgasm so loud that even Sunset was surprised. Of course, it only encouraged him to buck more rapidly and to push his fat cock even further up her pussy. At the same time that Suni reached her second climax, Sue's cunt unloaded a thick slime of girly juice into his mouth as she, too, exploded violently. Sunset needed to hold her thighs to stop her from falling backwards.

Seeing that Sunset hasn't cum yet, both Trixie and Sonata grab hold of Suni's smaller body and between them, pump her up and down on Sunset's cock, while sucking on her large breasts. All awhile both Aria and Adagio continue to lick and suck on Sunset's juice covered cock and play with Suni's cunt. Making Suni scream out in pleasure as she made to ride out one orgasm after another, both her sister and mother stretched their necks to join on licking on Sunset's cock to get him to cum faster.

Finally after a hour of sex, Sunset fires his hot load of cum into Suni's womb, filling her up with his seeds. The amount of cum caused Suni's belly to bulge from the volume of cum being pump into her belly. Finally Sunset stop cumming and Trixie and Sonata quickly pull her off and place her on the bed, they grab Mina and lift her up in the air. Aria and Adagio who lick up the cum covering Sunset's still leaking cock, guided the fat head to Mina's cunt hole. Trixie and Sonata slowly lowered Mina onto Sunset's cock, made easier thanks to the cum and her sister's sex juices covering it. Sue watch with lust as her other daughter is being treated the same as her sister who is completely fuck dumb by Sunset and his other women in his herd.

Sue looks down at Sunset who she's still sitting on his face, and still enjoying his talented tongue. She can't wait for him to father children with her daughters and maybe give them new sisters. Sue stretch her neck again and rejoins in licking and sucking on Sunset's balls awaiting her turn with the stud her family managed to become apart of his herd.

Later -

Sue lays on her back as Sunset has both of her legs up in the air as he plows his bitch breaker cock into her cunt. Both of her daughter's heads are sucking on her huge breasts as Mina's body is being played with by Aira and Trixie and Suni is being played with by Adagio and Sonata. The pairs are working their fingers into the gooey cum fill cunts working more of it into them and licking clean their fingers.

Sue is completely out of it, having been fucked dumb by Sunset relentless sex drive. He has fucked her and her daughters 9 times each before cumming and switching between the 3, till they're all completely out of it, not that it stopped him. The pony up Sunset is a true stud, being the one who mates with his herd of mares to insure that all the foals and fillies are his.

Sunset came again, filling up Sue's already cum pack womb and kept pumping for several minutes before he stopped and just let his cock rest inside of her. Before pulling out and a flood of cum came out of her cunt, no longer blocked by his cock. He turn to the others and saw both Mina and Suni completely out of it and both can no longer able to go on.

"Girls it's your turn now," Sunset said.

"Good," Adagio said as she and the others place the two sisters on either side of their mother on the bed.

Sunset arranged them so that Aria is bent over on the edge of the bed, being the strongest physically she's able to take what he has planned for her and the other. He place Adagio on Aria's back, followed Sonata and finally Trixie. All four bent over with their wet cunts ready to be taken by their stud. Sunset bends over the bodies on the pile in front of him and rubs his sex juice covered cock up and down on the cunts, causing them to moan as they were teased by him.

Trixie gasps as Sunset works his cock into her dripping cunt working his way into her tight hole, then moans in displeasure as he stops and pulls out. Adagio gasp as he began thrusting into her cunt then he switched to Sonata who gasp and moans feeling his giant cock inside of her, followed by Aria who is pin by the 3 bodies on top of her causing the stack of bodies to shake.

Sunset spent the next few hours switching between the 4 tight cunts in front of him. Even as he was cumming he would cum inside one of them for a few seconds before switching so that all of them would be filled by his cum. Then he repeated it over and over again, causing them to cum again and again. They all could only lay there on a pile as Sunset switch between them and made them cum before he pulled out and did the same to another.

"They're all completely worn out," Sue said who has recovered with her daughters Suni and Mina who are still nestled up against their mother's sides.

"They're all out cold," Mina said.

"Hey with them so full of your cum and it dripping out and them stacked on top of each other. It looks like a fountain," Suni said stretching her neck to look at the girls dripping cunts.

From Trixie's overstuffed cunt, came a steady flow of cum that went down onto Sonata's cum filled cunt, mixing with her juices and dripping down. Mixing with Adagio's over filled cunt and her juices and mix with Aria's and her juices. Which drips on the bed and on the floor that forms a small pool of cum and sex juices.

"You're still hard," Sue said staring at the hard cock in front of her and glance at the clock which when she and Trixie came back to the house was around 2 and it's now almost midnight. Which looking out of the window seeing it's already dark. "You been fucking us for at least 10 hours without a break."

"Ready to go another round?" Sunset ask before the pony up transformation finally wore off. Turning Sunset, Trixie, and the Dazzlings back to normal. The lost of mass cause the stack of bodies to fall over, Trixie and the others still out of it.

"How about we go to the bath and clean up and use the toilets first," Sue said getting up.

"I guess, I can get something to eat and drink first," Sunset said getting up and walking off to the cafeteria. Wondering what the other girls of his herd will think of his new pony up form.

Author's Notes -

1 - To pony up humans need to have a strong bond with the someone who has Equestrian magic, like Twilight and Sunset in cannon.
