It's been about a month since the failed transformation spell was used on Sunset. Both Celestia and Molestia were besides themselves as they look over Sunset. They all but lock themselves in their room taking care of Sunset while their sisters and Cadance handle the royal affairs. Trixie stayed with them helping with Sunset care, and after calling Ponyvile to tell the other herdmates what happen. Moondancer, Minuette, Lemon Hearts, and Twinkleshine came to help care for Sunset while the others remain in Ponyvile. All of them did what they could to help in the care of Sunset who spent most of the time laying on the bed and eating regaining her strength and body weight.

Sunset was fed rich food that adds pounds and drinking her moms rich milk and her aunts when they traded places with their sisters. After a few days had past and Sunset showed signs of recovering, Moon and Luna talk her moms into letting them look after her during the daytime so that they can attend to court duties and the would sleep with Sunset in their bed. Cadance who is staying at Canterlot for awhile has been helping but the paperwork still piles up, as the four princesses hover over Sunset. Sunset's herd mates helped out with what they could do, but mostly they were stress relief for the princesses. Which is them being fuck silly by the princesses when there aren't any ponies around or when they're in their room.

Sunset also spent that time not only recovering but relearning to use magic not that she has her horn back. Then there are her new wings that made her an alicorn, which had never happen before. Her moms and aunts are teaching her to use her new powers and to control them as she has the strength of an Earth Pony now. As for flying her moms and aunts waited till she was well enough to use her wings. She's been exercising her new wings by flapping them to build up her new wing muscles. As an alicorn her body is that of an Earth Pony which is much heavier then a Pegasus or a unicorn. Which is why she is so strong, as her body needs to be able to power her wings to lift off the ground. (1)

"Now just keep flapping your wings like that," Celestia said as she and Molestia watches Sunset lifts herself off the bed so that if she falls it be on the bed. Sunset with her new wings had to have new clothes made for her which is why she like the other ponies in the room are naked. She does wear underwear and shorts but all of her dresses and shirts had to be replaced or altered for her wings.

"Was it this hard for you?" Sunset ask Cadance as she learns to fly.

"Yes but I did it outside," Cadance said who is sitting on a couch as Twinkleshine suck her cock. And with her are Luna and Moon who have Minuette and Lemon Hearts also stuffing their mouths with their cocks.

"Sunset is still in no shape to be outside," Molestia said.

"She is a hybrid now," Moondancer said as she takes notes on Sunset.

"Why are you taking notes?" Trixie ask who is laying on one side of the bed that Sunset is hovering over. She's been taking it easy since the others came to the castle, enjoying not being the only one the princesses can have sex with.

"Half human and half pony, this is the first time something like this has happen," Moondancer said having been studying Sunset's body while helping to take care of her. "Sunset is an alicorn cause by all five princesses using their combine powers. But she is only half as powerful as she should be."

"But is is still enough to give her the lifespan of a full alicorn and once she's in full health also what comes with having the body of one," Celestia said having done many magical scans on Sunset.

"Her body just needs time to adjust to her new powers. Her new body mass, horn and wings ate away on her body to grow instead of using our magic. The spell can't be used again on Sunset," Molestia said.

"It... was painful," Sunset said as she settles back down on the bed. "My body is just too different to work the same as the rest of you when it comes to magic."

"At least you can use magic now," Moondancer said.

"That's true," Sunset said.

"And you're healthy again," Trixie said eyeing Sunset's rear as she's on all fours flapping her new wings.

"Not something, I want to go through again," Sunset said.

"In fact you're healthy enough for some sex," Trixie said as she hops onto the bed getting in front of Sunset with her cock in her face.

"Hey!" Sunset said frowning as Trixie's giant horse cock is in her face.

"Yes we should test out your body when it comes to sex," Moondancer said joining Trixie on the bed with her cock pointing at Sunset's face.

"Sunset is healthy enough now," Molestia said.

"And it be nice to see how much Sunset's body changed. Sunset's human body was much more fragile then a human body. But remember you two not to go all out on her. She is still recovering," Celestia said.

"It be nice to see if your body be able to handle us, without us having to hold ourselves back so much," Moondancer said.

"That's because I'm smaller and can't have your cock stuff to the hilt inside of me. I mean just look how far it would reach if you stuff all of your cock inside of me," Sunset said as she used her hands to measure Trixie's cock and then place her hands on her body from her cunt to her chest. "As you can see that it would kill me. You're just too big and long to fit inside of me all the way."

"You are small," Cadance said still enjoying her blowjob. "But now you have a pony body, you're much more stretchable. You seen how bloated ponies become after either your moms or aunts cu in them."

"I seen that first hand, moms and aunts double team on Pinkie after she wanted to fuck my butt. Which I'm not ever going to do. There is no way I'm ever going to let anyone butt fuck me. And the rest of the herd knows what happens if they fill me with too much cum at once," Sunset said.

"She throws up which kills the mood," Trixie said.

"And left a mess in the bed when it happen the first time," Celestia said remembering what happen when Sunset was still getting use to having sex with her herd for the first time.

"You should try it, you might like ," Moondancer said.

"No!" Sunset snaps. "There is no way that your cock would be able to go up my butt without it being painful for me. My cunt up to my womb is made to be able to stretch and expand seeing how a child's body is bigger then your cock. Besides its dirty!"

"Now Sunset we do clean it out after we use the toilet," Trixie said.

"Yeah the toilets have the water jet thing," Sunset said. "But there is still no way I'm going to take anything up my butt."

"I'm surprise no one has tried," Trixie said.

"She uses the threat of her moms and aunts all using their real size on anyone who tries, double teaming their butts," Moondancer said.

"Which we will do," Molestia said.

"Yes it's so lovely to watch as a mare screams her head off as we share her asshole between us. And now that there's four of us we can double team both their butts and pussy. Or even see if that can't take all four of us in one of their holes at once," Moon said.

"That would either kill or completely ruin a mare," Luna said.

"Well it's not like we haven't done that before," Molestia said.

"I read about it in your dairies," Sunset said.

"I really shouldn't had left them out," Celestia said still not liking how Sunset read all of her dairies learning all about her life that she never shared with others.

"At least Sunset won't just blab your secrets out," Luna said.

"She did say that Starswirl's special talent was in astronomy and in not magic," Moondancer said.

"That's true," Molestia said.

"She work at studying magic harder then anyone else. She didn't had much of a sex life because of that and kept to herself," Celestia said.

"And she in her old age became quite the pervert to make up her lost time," Molestia said.

"Sounds like Twilight before she got into the herd," Moondancer said.

"Which reminds me," Trixie said as she taps her cock on Sunset's lips.

"Fine," Sunset said taking Trixie's cock in her mouth licking it.

"Oh yes, that feels so nice," murmured Trixie enjoying herself. "You are such a talented at cock sucking."

Sunset cringed at the comment, but bent her attention to the huge cock meat in her mouth, running her tongue all up and down the shaft and licking around the head as if it were the sweetest treat in the world. Which she had gotten a taste for since coming to this world and started having sex. Precum dribbled from the cock and onto her lips as she licked and sucked at the dick. Suddenly she felt hands behind her lifting her ass up into the air and she realized that Moondancer had moved behind her. Sunset knew what was coming next but she doggedly continue to suck and lick the cock of Trixie in front of her. She felt a hard object throbbing against her pussy lips and then suddenly there was a thrust from behind and she was impaled on the cock of Moondancer. Twelve inches of a twenty inch cock was sliding down her throat as another twelve inches of a nineteen cock slid up her pussy. Both Trixie and Moondancer could only put so much in her before it started to harm her and they held back as Sunset's moms are watching. With two feet of cock inside her, there was little that Sunset could do but kneel there and get fucked by her two herdmates.

Moondancer behind Sunset reached around to grab handholds on the Sunset's new big hanging tits and she pulled herself deeper inside Sunset seeing how much Sunset could take, while Trixie grabbed the back of Sunet's head and forced more inches down her throat also wanting to see how much Sunset's new body can now take. They only stop when she started to struggle between them as they reach the limits that her holes could take. Both Molestia and Celestia got on the bed watching as their daughter was spit roasted in front of them, ready to stop the two fucking ponies if they start hurting Sunset.

Gently Trixie and Moondancer fucked Sunset in perfect harmony. All the while they told Sunset she's gotten good at pleasuring her headmates and how nice her mouth and pussy felt on their cocks. The two ponies seemed in no hurry to cum and it seemed to Sunset that they fucked her face and pussy for hours with nice steady motions, making her cum again and again. They would both pull their cocks out so just the heads were inside her and then ram them back in deeper than ever until Sunset who felt like she was going to be split in half. On and on they fucked her, enjoying the pleasure her mouth and pussy was giving them until finally they pulled out and flipped Sunset over onto her back and in lock step gave their cocks three more hard strokes and each shot a big sticky load over one of Sunset's tits. The two came so much that the cum ran off of Sunset's tits like twin waterfalls to form pools of cum on her stomach.

They then lean down and began licking the other's cum cover breast, enjoying the taste of the other's cum, before going for the pool of cum on Sunset's stomach. Sunset took the time to look around and saw that Luna and Moon are now fucking both Minuette and Lemon Hearts from behind, while pressing their bodies together squeezing their big breasts together and them locking lips as the two princesses fuck them. And on the bed besides her, both her moms have Twinkleshine sandwich between them as they fuck her pussy and ass at the same time. Sunset look in front of her to see Cadance stroking herself as she prepares to have her turn with her pussy.

"Now that you're all lubed up you be able to handle me," Cadance said licking her lips as she lined the tip of her giant pony cock against Sunset's well used pussy lips. At 23 inches Cadance is much bigger then any cock Sunset had ever taken.

Cadance slowly press her cock into Sunset working her cock inside of her, using the cum already inside of her as lube to ease herself into Sunset's tight body. Sunset shivered as more and more of Cadance monstrous shaft was disappearing up her pussy. Finally Cadance had about more then half of her cock in when she bumped into Sunset's cervix. Sunset cried in pain mixed with intense pleasure causing both her moms to turn their attention to Cadance who got the message to stop trying to fit more of her cock into Sunset. She started ramming home about ten inches of her massive cock while keeping the head inside of Sunset, literally masturbating herself with Sunset entire body. Sunset hair was thrown in all directions and her tits jiggled even as Trixie and Moondancer after finishing licking off their cum on her started suckling her new breasts that are now in the D cup range. Strands of viscous juices were dripping onto the bed, forming a puddle of hot cream. Cadance licked her nipples pushing Trixie and Moondancer away so she can have her turn, squeezing them with her teeth while she continued to pile-drive her colossal cock into Sunset again and again. She could feel Sunset cuntwalls sucking in her rod, expanding to their limits to take in her oversized cock.

Sunset on her part lost count how many times she came as she was fuck by Cadance showing what being fuck by an alicorn is like. She was screaming her head off, till both Moondancer and Trixie presented their cocks to her mouth. She began stroking both of their cocks giving them hand jobs that she learn from experience how to give and licking or sucking on their cocks as she did. Both of them lean forward and began suckling on Cadance breasts drinking her milk as they enjoyed Sunset giving them both hand jobs and blow jobs. Cadance reaching her limit thanks to Sunset's tight pussy but remember not to cum full stop inside Sunset so as she was cumming she pulled out.

Cadance cock freed from the tight pussy of Sunset sprayed it's load all over Sunset's body. Both Trixie and Moondancer joined her in spraying down Sunset with their combine cum. They plaster the young princess's face and bosom with salvo after salvo of warm pellets of goo.

"You're drowning me in your warm spunk! More, MORE!" Sunset encouraged them, rubbing the layers of cum already covering her upper chest like it was body lotion, occasionally scooping some of it to messily slurp it up.

Thirty seconds into the cumfest, Moondancer and Trixie's cumshot started petering out but Cadance's massive batter rockets showed no signs of appeasement. Which is just like how both Sunset's moms and aunts do when they cum. Cadance unleashed torrents of goo over Sunset, outpacing the combined efforts of Trixie and Moondancer both in terms of number of wads, and volume of cum. Only after over a minute of non-stop cumming did her cum-cannon start slowing down, but she still managed to unload an extra half-dozen smaller spurts, each more plentiful than a pornstar's total orgasm. By the end of it, Sunset had received gallons of virile pony spunk over her face, hair and body. Ounces of cum were splattered all over the floor and the bed sheets. The delirious young alicorn fell back on the bed, wriggling her body over the warm layers of spunk, greedily eating up as much cream as she could muster, a immense smile covering her face.

"My turn," Trixie said taking Cadance place between Sunset's legs with her cock rock hard even after cumming.

"Give it to me," Sunset said as she settles down to another non stop orgy with her in the center of attention. Her new body is able to handle the amount of sex that ponies of this world can handle. And she is really getting into it, her body just responses to all the sexually pleasure that the ponies of this world seem to be made for and found herself loving it. With her new body she will really be enjoying herself instead of just letting her herdmates use her like a sex doll. She wonders what it be like when all of her herdmates join her.

Author's Note

1 - Pegasus have hollow bones, smaller body size and the lightest in body mass of the pony tribes. As even with magic they would have to have lighter weight then other ponies to be able to fly.
