Rainbow Dash walked into the party with her father, Bow Hothoof, pacing her. The known parent of a year-old foal and hidden parent of the same foal had gone with low effort costumes of a pair of togas and some birch leaves in their hair. As she took in the festive spooky atmosphere with a smile, the host of the party came up to greet them.

"Rainbow, so glad that you could make it this evening!" Twilight proclaimed with a brilliant smile. The lavender alicorn was dressed like a classic movie robot, complete with disk-like bubble covering her head. "I was worried that Prism was going to keep you from showing up."

Rainbow smiled fondly as she thought of her colt then directed it at her best friend. "Mom is watching him for me, and Daddy offered to be my plus one, so that's why he's here." She smirked internally as she thought about how he needed a break from watching him just as much as she did.

Twilight nodded in understanding. "It's good to see you again, too, Bow. Feel free to mix and mingle, the only pony you might not have met is my brother. He's in from the Crystal Empire because Cadance is feeling moody and wanting some space while she's pregnant." She nodded to a white unicorn stallion with an electric blue mane dressed all in white, a toy ray gun holstered on his side.

Bow's expression shifted as he tried to remember if he'd met the stallion before and ended up shrugging. "Don't think we've crossed paths before, but parties are good for that." He turned back to his date. "You want me to stick around, honey, or do you want some time to talk to your marefriends?"

Rainbow waved off her dad. "If you want to, you can go find some ponies who aren't going to be hock deep in mare-talk." She turned back to Twilight. "So are the rest of the girls here?"

"Fluttershy begged off, you know how she is about both parties and Nightmare Night, so she's holed up at her house as far as I know. Pinkie Pie is supervising at least one of the parties for the foals. I'm wanting to say it was Diamond Tiara's party." She shrugged before continuing on. "But Applejack and Rarity are here with Big Mac and Sweetie Belle."

Rainbow gave Twilight a puzzled look. "Are the rest of the crusaders here? You normally can't break the three of them apart with a crowbar, let alone for a party."

"Scootaloo and Applebloom are at one of the other parties with their coltfriends. Both of their coltfriends are a little too young for this party from what I understand." Twilight explained with a shrug and a smile.

Rainbow nodded in understanding. "Makes perfect sense to me. Don't have to worry about the fillies and colts getting into the booze if they aren't here to begin with." She looked out across the room to see the few ponies that had stuck around the entrance. Several of them she didn't recognize, but she did see the town klutz dressed up in a blue skirt, white top with a large red bow. Around her head she had a gold tiara with a red stone in it, and had her mane into two odd pigtails that fell from two small buns on either side of her head.

She noticed with a smile that she was accompanied by Doctor Hooves dressed in a caped tuxedo with a top hat and a white domino mask. "So those two finally are together? All of us in the weather team were sure that they would eventually start dating."

"Yeah, they got together about a year ago, so right around when you gave birth." Twilight explained with a wistful smile. "I've gone past him looking at rings while she's not around, so I think it's pretty serious."

Rainbow smiled happily for the loving couple. "They're cute together, so I'm not surprised he's thinking about it." She spotted a couple of ponies she knew standing outside chatting together, Caramel and Roseluck. Caramel was dressed in a fur loincloth while a plastic sword sat in a scabbard at his side while Roseluck was dressed in a red cheongsam and had an indigo wig on. Giving them a wave, Rainbow walked inside.

Rainbow had found a couple of friends from her weather team inside dressed completely differently from each other, but considering that Cloud Chaser and Flitter were twins, the idea of matching costumes had likely gotten old long before they were old enough to drink. Cloud Chaser was walking around in a chainmail bikini and a red wig, while Flitter was doing her best to strut in a red tunic and black pants. "Hey Cloudy, hey Flitter!" Rainbow called, walking up carefully to the twinned duo. "How are you?"

Flitter did her best deep harrumph, that ended up turning into a giggle. "We're good, Dash. How's your little one?"

Rainbow gave her an excited smile. "He's good! He's starting to talk, so I've gotta be careful about what I say around him. Can't have his fifth word be a swear." She said this last with a grin.

Cloud Chaser laughed. "Yeah, he needs to be a flier like his mom, not a sailor." She looked around. "So when are you coming back to the weather team full-time? Wrangling the Everfree's storms has been a lot harder since you went on maternity leave and then part-time."

"I wish I knew. Prism's a good foal, but he's still really needy. Mom and Dad are great about watching him, but they have lives of their own." Rainbow didn't mention that she emphasized with her Mom more than her Dad, seeing as Prism was his, after all.

"It's too bad you can't find the dad. Him sharing parenting duties would be the absolute minimum he could do." Flitter said while her twin nodded along.

Rainbow let out a resigned chuckle. "It's why you shouldn't get wasted at a party, Nightmare Night or otherwise. If I hadn't, I might have some more ponies to help out." 'I'm just glad everyone bought that lie.' She shrugged and smiled. "All the same, I'm going to go look around more. I'm hoping to find Rares and AJ."

"I think I saw Rarity and Sweetie Belle going into the library, while Applejack and Big Mac went into the dining room." Cloud Chaser said, pointing out which was where in turn. With a smile, Rainbow walked to the library, figuring that she'd end up talking far more with Applejack than Rarity.

Arriving inside Twilight's favorite room, she saw both Rarity and her sister. Rarity was dressed in a brilliant white dress with huge, poofy sleeves, while Sweetie Belle was dressed in a pair of tight gray slacks with a white blouse and black vest. Rainbow was about to talk to either one, but noticed that both were canon-deep in conversation with some ponies that Rainbow didn't immediately recognize. Rarity spotted her out of the corner of her eye, turned, blew her a kiss, then mouthed "later" to the former daredevil. Understanding that her friend was likely going to be busy dealing with fashion business, and her little sister with music talk, Rainbow gave her a nod of understanding before walking on toward the dining room.

Like the rest of the palace, the dining room had been made up tastefully in Nightmare Night decorations, complete with streamers that had a laughing cartoon Nightmare Moon on them. 'I wonder if Luna gets anything from the company that makes those' Rainbow thought as she looked for her best friend and former fling. After a brief amount of searching, she found first Big Mac dressed in all black, a black eye-mask obscuring his eyes while a black bandana hid his hair. Curiously, he had a plastic rapier at his waist, that he'd occasionally draw and talk about sword-fighting to a couple of listeners, including a particular orange mare.

Rainbow Dash smiled at Applejack, taking in the muscular mare's costume. Dressed in a flowing white dress, a black necklace and a circlet that seemingly did nothing to control the mass of ringlets that she'd turned her mane into. "AJ!" she called excitedly. "So good to see you!"

Applejack turned with a smile of her own. "Rainbow! I didn't think you were going to be able to make it! Your parents watching Prism?"

Rainbow waggled her hand in a so-so gesture. "Mom is, but I invited Dad along because he watches Prism almost as much as I do, so he needed a break, too. So he's currently wandering around the palace, meeting ponies while I find you and the rest of the girls." She pulled the farmer into a hug, just enjoying the guilt-free contact with another attractive pony. "Your costume looks good on you, though I bet it was a pain to curl your mane."

Applejack laughed before replying. "It was actually one of the easiest parts. Rarity knew a spell, which is part of why I went with this costume to begin with. I thought about dying my mane black to match, but that felt like too much. I've had a few ponies guess who I was supposed to be, but they've not had any luck yet.

"I'm dressed in a toga because it was easy and all I needed was a white sheet. I didn't have a character in mind when I made it." Rainbow shrugged, careful of her breasts breaking free of the tape keeping her bust contained within the toga. "So who are you supposed to be, exactly? I've got a good idea who Big Mac, Rares and Sweetie Belle are supposed to be, but no clue for you."

Applejack shook her head. "I ain't saying until you've at least guessed twice."

"Since I recognize your brother's costume, I'll knock out the theme guess first. Buttercup."

Applejack shook her head again. "Guess again, sugarcube. You've got the right idea, but I'm somebody else."

"Galadriel?" Rainbow had taken a little longer to guess this time, seeing the repeated shake of Applejack's head, Rainbow shrugged. "I really have no idea, how about you just tell meeeEEEEE!" It was at this moment, Rainbow saw it, an item from her nightmares, her very occasional fucked up wet dream, and a couple even more fucked up masturbation sessions. The pumpkin statuette that had possessed her father, used her body, and gotten her pregnant. Seeing Applejack's concerned expression, Rainbow didn't bother trying to play off her fear. "Applejack, do you know where that statue came from?" She pointed at it, trembling.

Applejack tilted her head to the side as she struggled to remember. "I think Big Mac bought it at a thrift shop around this time last year. He didn't have an immediate use for it, and tossed it in the back of the barn until this party. Why?"

"That cursed thing is why I'm a mother, that's why!" Rainbow hissed in fear. "We need to get it out of here, preferably to the moon or even further away!" She shakily grabbed it off the table, spilling the surrounding decorations on the floor and table. "We need to get to Twilight, NOW!" She handed the statuette to Applejack before flaring her wings.

"Rainbow, what are you talking about? It got you pregnant, how is that possi-BLE!?" Applejack yelled as her daredevil friend grabbed her by shoulders, lifted her off the ground, and started to fly towards the entrance where Twilight had been before they got started.

Unbeknownst to either of them, both of them had had wardrobe malfunctions, both of their breasts popping out of their respective costumes while Applejack's flowing dress had revealed the fact that she'd neglected to wear underwear to the party. A fact that Big Mac had noticed. A fact that had developed into a peculiar expression on his face and a certain glow underneath his mask.

-

With shouts of surprise at the sheer wind-speed that Rainbow created as she flew through the palace, she finally found Twilight talking with her brother. "Twilight! Teleport!" She yelled while panting. "Get rid statue!" She pointed to the statue that Applejack had dropped to the floor after noticing that her breasts had popped out of her dress. "Trouble if stays!" Rainbow continued to pant, her face white with terror.

Trusting her best friend with her life, and having never seen her this scared before, not even during Tirek's rampage, Twilight immediately powered up her horn and sent the pumpkin statuette into deep space. Sensing that the immediate danger had passed, she turned to her friend, searching for an explanation. One that came haltingly when Rainbow finally caught her breath.

"If you could make it so no one else could hear us, that would be great, Twilight." After another burst of magic, she started telling two of her best friends and the brother of her best friend what happened. "Two years ago, the night before Nightmare Night, I had a 'bad movie' marathon with my dad. Something we've done since I was just a filly. He'd found that statuette at a thrift store, and had it on the table. We watched a couple of movies, and when I got up to go to the bathroom, he noticed that I had turned into a pretty mare. He idly wandered what it would be like to be with me, and that was enough for the ghost in the statue. It possessed him, and it used my Dad's body to rape both of us. It got me pregnant, and sent us both to therapy."

All three listeners' faces fell, hearing about the trauma that Rainbow and Bow had gone through. "That explains why you didn't try too hard for me to find who knocked you up. You already knew who the dad was."

Rainbow nodded, tears of relief starting to form. "It's why he's been the primary one to help me raise Prism, too. Only right for the Dad to do around half the work, after all." And she gave her friends a small, pervy smile. "And while we've had to be careful, we've had some fun together since. It's helped us deal with the trauma."

Shining Armor spoke up at this revelation. "I suppose I should stop you from doing that, considering that it is against the law... but considering that you're both adults and it appears to be helping... I heard and know nothing." He gave her a thumbs up and a conspiratorial smile.

Rainbow let out a guilty laugh. "Oops, forgot that you're technically still part of the guard. Thanks for letting me go, officer!"

Twilight dropped the sound-blocking spell before speaking up. "If you want to talk about it, Rainbow, I'm always available to talk. Just let me know and I'll clear my schedule."

With that, a mysterious voice began to echo through the palace. "It's good that you're always available to talk, Twilight Sparkle. You're going to have to clear your schedule a lot, though." With a dark and lusty laugh, the voice continued. "Mostly because you'll be busy being enslaved to your brother." The laughing continued, and then stopped just before a burst of of yellow light overwhelmed Rainbow and her friends before everything went dark.

A distant moaning drifted past Rainbow's ear, causing it to twitch. A moaning that sounded distinctly pornographic. A pervy smile developed on her face. 'Daddy must be watching porn before coming to wake me up. Prism must have gone down for a nap easily and he's aching for some fun.' She shifted her position, running her furred and largely naked body against the smooth, cool surface she was on. 'Wait, this isn't my bed!' Her eyes opened, and a strange and foggy half-light filled her vision. "Am I in Twilight's basement? How did I get here?"

Thinking it over, she thought back over what she remembered. "Came to the party with Daddy, met Twi, saw Rares, and had a short conversation with Applejack. She was trying to tell me what her costume was." She began to tap her fingers together as she tried to concentrate and remember what exactly had happened. "And I saw something on the table. And I took it to Twilight... And I can't remember anything else." She stiffly stood up, taking note of the poor state of her toga as she did so. "Well, glad I got this sheet for cheap, because this thing is shredded. I don't even know if I'll be able to use it for rags."

Looking around, she found a set of stairs leading up into what she thought would be the kitchen. As she walked, she wondered if she'd hit her head. "Did Twilight decide to mix a Nightmare Night spell with a Hearts and Hooves illusion? It's like there's figures of smoke fucking." She continued to climb, a blush growing on her face as she saw more and more lewd activities within the smoke. A quick walk through a kitchen full of platters of food under what were probably stasis spells finally brought her into a massively changed dining room.

Four tables piled high with h'orderves surrounded an obvious translucent magical shield. Within the shield were two deeply familiar figures. Applejack's dress had been ripped from her body save for parts of the sleeves and the collar of the dress laying on her neck, while Big Mac was naked save for the mask and bandana combo almost disguising the golden glow in his eyes.

Applejack hung upside down, legs held up by two yellow tentacles. Her mouth and throat had been stuffed full of her brother's cock, which looked to have gone from large enough to please all but the most demanding of size queens to a size that a giantess would be intimidated by. Big Mac groaned as he thrust his mare-breaker deep within Applejack's mouth, while somehow having to presence of mind to make his extra-long tongue tickle the interior of Applejack's cunt.

A hauntingly familiar voice echoed from the room and from Big Mac especially. "Ah, the prodigal mare has awoken. My love who rejected me, but not my gifts. Bow's mind is a treasure, Slut. I can see just how wonderful of a mother you've become, and how good of a lover you are, too." The voice chuckled before continuing. "I will allow you to wander the castle, and see what I've done to those who have joined me, willing or otherwise. Allow you to wander, and prepare yourself for when you find Bow and rejoin your master in blissful submission."

Rainbow's breath caught in her throat as everything came back to her. The return of the statuette, and more importantly, how to defeat the spirit within. Taking a deep breath, she began to shout. "Applejack, for the love of everything, don't agree to anything it demands of you. Hold out until sunrise, and everything will be okay!"

That Applejack had heard or understood her words was hard to tell, as Big Mac let out a thunderous groan and immense pulses began traveling down his dick, through Applejack's mouth and throat, and directly into her stomach. Her work-hardened abs quickly lost definition as her stomach inflated from the semen hose pumping into her stomach. Tears fell from her eyes, both from fear and the discomfort of having her throat fucked.

Once the flood had ended, Big Mac began the laborious process of extracting his behemoth of a cock from his sister's maw. Rainbow could see that he was saying something, but couldn't quite hear it. She got closer to the shield, and could finally understand what he was saying. "You're a good cocksucker, eeyup! Gonna breed you now. Can't ever let you go, eenope!"

Knowing that this was the last chance she'd have to communicate uninterrupted with her best friend, Rainbow shouted as loud as she could. "Don't agree to anything, Applejack! Make it to sunrise, and this will be all over!"

Applejack had been hard at work trying to clear her lungs, but Rainbow's words managed to reach her. "I-I... I'll try!" That was the only sentence she could get out after getting the cum out of her throat and lungs. The tentacles shifted her about, holding her arms behind her while she was bent over at the waist. She let out a little shriek as her brother's titanic erection penetrated her seemingly too small pussy, stretching around its immense girth. With an orgasmic scream, her still swollen stomach bulged around the invading phallus as her torturous ecstasy began.

Rainbow shuddered in horrified arousal as she began to run away from the scene, unable to help and feeling deep shame at the fact she was now dripping wet. The only door that lead away from the dining area went to the library, so lacking any other options, that's where Rainbow went.

Like the dining room, the library had changed as well. Twilight's library normally had books that covered most any topic. Magic, science and history all had pride of place, with a few atlases rounding out the nonfiction. The fiction section was smaller, but the tomes within were much loved and great for when the bookish mare wanted to relax. All of that had been changed. Magical books for enhancing sex, dominating one's partner, and changing the body now filled the magical section, while books of pornographic pictures and the history of sex cults made up the science and history sections. Fiction was entirely made up of stories of heroines becoming the gleeful property of a dominating stallion or mare.

Rainbow walked through the shelves that had been moved to create a maze, the familiar sound of two mares fucking filling the room. Through seemingly endless shelves of smut she walked, coming closer and closer to the sound of pleasured mare. The occasional scream of forced delight echoed off the wood, giving Rainbow insight into the identity. "That's Rarity, I'd recognize that scream anywhere after saving her from falling." She said to herself, voice dripping with helpless frustration and lust.

Finally, she managed to get to the source of the screaming, and found something truly unexpected. Rarity's white dress had been shredded from her body, exposing her silky belly fur and pert tits, the shreds of her dress used to bind her arms behind her. On a more surprising note, Sweetie Belle's eyes had picked up a yellow glow, while only her white blouse remained, her black vest and gray pants had been haphazardly tossed into a pile away from the siblings. Rainbow noticed the stain of cum on Rarity's lips, and wondered just where it could have come from, considering that Sweetie Belle was clearly fucking her sister with a strap-on.

Seeing that her fashionista friend's eyes were glazed over, Rainbow moved around to the side so that she could understand exactly what it was that was happening to Rarity. A gasp escaped her mouth when she noticed what exactly Sweetie Belle was doing. Instead of using a strap-on to plunder Rarity's pussy, a flesh and blood cock was plowing her sister's ass. In an almost hypnotizing motion, the oddly feminine cock parted white-furred cheeks with a passion.

"Your ass loves my cock, Sis! It's so warm, wet and welcoming, almost like it was explicitly made for me to use. I'm going to use it forever and ever, you won't ever be able to sit right ever again! And yes, I'll breed you, but your ass is mine to use and abuse!" Sweetie's pale hand slapped her sister's even paler behind, leaving a red mark to slowly bleed through her fur. Rarity let out a squeal as her ass clenched on her sister's pounding rod, signaling that she was cumming from the rough treatment of her behind even before a gush of femcum squirted from her untouched cunt. A fact that delighted the possessed futanari mare. "Oh perfect, my darling anal slut came for me!" Sweetie Belle crowed. "So I'll have no complaints for using your ass as a cock sheath at all times, then."

Sweetie Belle started to fuck her sister's ass harder. "Rarity, your friend is watching me use your perfect ass. She's watching me break you and mold you into a living sex toy. Doesn't it excite you to know that she'll know just how hard you orgasmed as your little sister fucked away your free will?"

This was enough to cut through Rarity's orgasmic haze, causing her to launch herself forward, trying to get away from the deranged dom her little sister had become. An attempt that was only partially successful. The new sensation of cold air hitting Sweetie's cock-head was enough for the keyed up futa to finally cum. A veritable tsunami of semen spewed from the tip, soaking the floor, the walls of the magical cage, and Rarity's tail, mane and fur. Rarity let out a cry of disgust before shouting "You got it in my hair!" She tried to scrabble through the shielding magic, but her horn and body-check ended up completely ineffective.

Rainbow, who had been surreptitiously playing with her nipple during the show, finally recovered enough to herself to speak. "Rarity, I can't get you out of there, but if you can make it to sunrise without accepting any deals, we can all go free. Just hold on." She gave the white mare of a sorrowful look before adding "and I hope that you'll forgive me that I can't do anything more."

With that, she fled into the stacks, hopeful that moving on to a new location might do something to alleviate her guilt from being unable to do anything other than let her friends know how to avoid being enslaved. The books she ran past continued the previous theme of porn and submission, titles promising her bliss if she gave herself over to the spirit's control.

Eventually she found herself back at the locked entrance where she found Derpy and Doctor Hooves having a blissful time together, while Caramel and Roseluck were angrily yelling at each other as they fucked.

"Oh Doctor, I love you so much!" Derpy cried as her coltfriend plunged inside of her. Their costumes had ended up in a pile that they ignored in their hurry to fuck. "You feel so good inside of me, I wish we could be like this forever." Her beautiful yellow eyes focused entirely on him, love clearly written in them.

The good doctor gave her an affectionate kiss. "And I wish we could, too. And while it's not how I intended to ask, what with the both of us being naked, I have a super important question for you." He thrust harder into her accepting body, smiling all the same. "Would you make me the happiest stallion in the world and marry me?"

Derpy let out an outrageously cute giggle, then kissed him back before wrapping her legs around his back. "I love you so much, and of course I will. I'll marry you!"

On the other hand, Caramel slapped Roseluck across the face while she punched him in the chest as the two of them passionately fucked. "Fuck me, you bastard! Fuck me with the only part of you that's worth a damn! Stupid fucker, I knew I should have gone home when I saw you here!"

Caramel growled before slapping her tits. "You know you like hate-fucking me. You never could stay away from me and this dick." He bit her shoulder before even more roughly sawing in and out of her. "The bruises just make it better. You know it, I know it. So stop your bitching, fuck me, and punch me in the face!"

His head snapped back from her vicious right-cross. "You're right, the bruises do make it better, and the hate-fucking is great." Roseluck begrudgingly admitted. "But I still hate you, and hate that I still end up in bed with you."

Caramel hungrily kissed her before smiling. "I hate it too, but that just makes fucking you so much better." With a pair of cries, the two bestial lovers? came together, letting the two of them relax for the moment. The newly minted fiances ended up following them into their own climaxes.

Rainbow watched both pairs of ponies with confusion in her eyes, wondering at the seemingly normal behavior put on by both, and how they ignored her and the other parties present. She knew Derpy far better, so went up next to her. "Congratulations on the engagement, Derpy!" She said with as much enthusiasm as she could muster under the circumstances. The cross-eyed mare didn't notice Rainbow's words in the slightest, paying attention only to her fiance.

Rainbow was deeply confused, and tried to make herself known by shouting as loud as she could "Congrats, Derpy!" which also failed to get a reaction to the rainbow-maned mare's action. She began trying to physically shift her, even giving the gray mare a light punch with no effect other than Derpy shifting in discomfort. Throwing her hands up in frustration, Rainbow moved on, hoping to find something.

Rainbow found herself in a ballroom, a room she had been entirely unaware of the castle having. Within, two more couples were having intimate relations, but unlike the last pair of couples, there was clear evidence of possession within the two dominant members. Shining Armor had a bound Twilight on her knees fucking her large breasts on his massive erection while a futa Cloud Chaser was fucking a mare who appeared to be Flitter in a gimp suit from behind.

Both dominating partners had decided that humiliating their submissives was in order. "Twiley, you've grown into quite the mare, and your tits have grown even further. They're so fat and heavy that I wonder if you're actually a mare, though. As big as your tits have gotten, I think that calling them tits or breasts undersells them. Udders is the right word, and mares don't have udders, Twiley. Cows have udders, Twiley, and since you have udders, you must be a cow!" He pinched her erect nipples while continuing to thrust his cock between her well-lubricated tits.

Hearing her squeak in fear, frustration and arousal, Shining gave her an evil grin. "It's perfect that you've decided to let me have you. Cadance is going to need all the help she can get to feed our foal and me, and the spell to make a cow-slut like you lactate is foal's play." With a surge of yellow from his horn, Twilight's already impressive bust slightly expanded... and then expanded again. Cream-white liquid started to leak from her now heavy tits, lubricating his cock further. "Good cow, make plenty of milk for me, and I might even breed you. Good cows get bred, while bad cows end up stuck like this." A surge of purple and yellow energy shot forth from his horn and encircled her waist, sealing away her nethers from being touched.

Cloud-Chaser slapped Flitter's breasts through her thick suit, drawing a moan of pain from the masked and ring-gagged mare. "You've been a bad girl, Flitter; stealing my toys AND flirting with my dates. It's like you both want me, but also want to prove that you're better than me. Well no more, you ARE the toy now, and are going to be mine to use when I'm between dates." She raised her hips, running her cock over her sister's g-spot, causing the gimp mare to orgasm on the spot. "Oh ho, my toy is sensitive, I see. Well, I'll just have to train that out of you, toys exist for their owner's pleasure, not the other way around."

While it was impossible to see how Flitter was reacting to her sister's words, Twilight's face was perfectly visible when it wasn't eclipsed by her brother's cock. Rainbow could see slime coating her bookish friend's face, though it did nothing to obscure the fear and dismay etched into her features. It also did nothing to obscure the sound of dripping from her pussy. While Flitter would occasionally let out a moan when Cloud-Chaser did something, Twilight actually could talk. "Shiney, please stop! I know this isn't you! You love Cadance, and you don't want to hurt me!" she pleaded with a rough voice, tears trying to wash away the slime. "You're stronger than this thing, I know you are! Fight it, and stop hurting u-*upgh*!"

Shining Armor had grabbed hold of his sister's horn, using it to guide her mouth over the top of his cockhead as he flared. "Shut up and swallow my cum, Cow-slut. Your mouth is for use as a cum-dumpster, nothing more, so shut up and swallow!" Further and further her mouth descended on his cock, only the limits of her neck's flexibility preventing her from going further as he came down her throat. With each colossal spurt of seed, her stomach inflated, lifting her breasts up and making her look pregnant.

Having focused on Shining and Twilight, Rainbow hadn't noticed that Cloud-Chaser had cum inside of Flitter as well, flooding her womb with futa-cum and stretching the latex of her gimp suit. The cocks that had been tormenting their fuck-holes were removed, and Rainbow could see the consideration of both possessed ponies of what they would do next. Rainbow screamed out her next words, hoping to get through to both of them. "Agree to nothing, stall to sunrise, and you'll get out of this with your freedom intact!" With those words, Rainbow took off running again.

As she ran, she wondered why that all the ponies that she'd not recognized from the party were in the room fucking each other, but none of them were dominating each other like the ponies who were family members of each other were. It didn't make sense for what she'd seen of the rapist spirit before. Amazing at sex, sure, but gentle or tender were not words she'd ever use to describe what it did. And outside of the five couples she'd seen throughout the palace, only Caramel and Roseluck had anything other than loving interactions, and that was apparently normal for them.

She considered the problem as she ran, regretting the lack of exercise since she'd become a mother. However, she still had some conditioning, and could make her way through the palace. A word occurred to her as she ran, and what that word meant for the possessed gave her an epiphany. With her first confidant smile of the evening, Rainbow ran to find her father, hoping she had the means to finally end this farce.

-

Rainbow finally found herself in the map room, with the chairs that were supposed to be her and her friends' having been changed to various pieces of bondage furniture while the map showed chains starting to encircle three of her friend's cutie marks, and a hint of chains around her own. She also found the one pony she hadn't been able to find since this all started, her father. "Hello, Daddy" she called with some relief.

Bow turned to look at her, a subdued, lewd smile on his face and a dull glow in his eyes. "Hello, Rainbow. So nice of you to join me!" A pair of tentacles emerged from the air, just waiting to grab her. "Have you come to surrender so that this farce can end and all can join me in infinite pleasure?"

Rainbow took a seat on a spanking bench and shook her head. "Nope. I didn't give up two years ago, and I'm not going to give up now. And what's more, I can tell that Daddy didn't either. You've got nowhere near the control of him now that you did back then, and you won't ever again!"

A disdainful sneer replaced the lewd look, as he stalked over to her. "And WHY! PRAY TELL! IS THAT!?" the possessed stallion snarled.

Rainbow took to her feet, a determined look on her face. "Because we aren't giving you what you feed off of anymore! I love my father, and I'm not ashamed of what we've done! I love our son, and if it weren't a jail sentence, I would happily proclaim my love to the world!" She looked the cause of the dull glow dead in the eye, and with a snarl she shouted. "I love him, and you're not going to take him from me! Now get the fuck out of him, and then fucking leave this palace, or the sun will be the least of your fucking worries!" She grabbed her father by the shoulders, and pulled him into a fierce kiss.
