Time Out

Apple Bloom was stirred awake along with Applejack as she woke up, turning over in bed. Apple Bloom righted herself in the pitch dark and tried to stand, finding her head just barely touching the top of the room. She panicked for a moment, worried that the room was shrinking around her. The wall pressed against her face as Applejack rubbed her belly. "Ooh, she's getting bigger!"

That made more sense.

"Hey!" Apple Bloom yelped.

"Bloom, was that you?" Applejack asked her belly.

"You know it is!" Apple Bloom yelled. "Can you let me out now!?"

"No can do, buckaroo," Applejack said. "Even if I could, you ain't done growing yet. You're still way too small."

"But these sure ain't!" Big Mac said, leaning over in the bed to suckle Applejack's swollen teats. Through her connection, Apple Bloom could feel her nipples tingle. Big Mac's baritone voice hummed through Applejack's body. "I've missed this too," he said, drinking his sister's milk.

"You're looking ready for another round, stud!" Applejack said. Apple Bloom kicked the wall of her little room. "Oh, I can feel her kicking!"

"I ain't ready for another round!" Apple Bloom yelled.

"Ooh, it sound's like somepony is cranky," Applejack teased. "Is it feeding time already?"

Before Apple Bloom could even object, she was knocked off her hooves as Big Mac grabbed Applejack's hips and lifted them up into a breeding press. Applejack's womb was squished around Apple Bloom, pressing her face up against the inside of her cervix. Big Mac pushed his dick inside Applejack, finding that there wasn't quite as much room inside her vagina, with Apple Bloom taking up more real estate inside Applejack's abdomen. He gauged his depth taking care to mostly not hit her cervix too hard. Mostly.

Apple Bloom could feel the impact against her cheek each time he bottomed out inside Applejack. But by now her shock and disgust had been replaced with simple indignation, forced to experience them having intercourse, and her along for the ride whether she wanted to be or not. "Really? Again!?" she complained.

Applejack just rubbed her belly to try to sooth her. "Oh, Bloom, if you ever had a dicking this good, you'd be addicted to it too." The connection they shared didn't let Apple Bloom feel the explicit sensations that Applejack was having, getting filled so perfectly with her big brother's dick. But she did feel the general sense of intense sexual pleasure from the act. Her own pussy quivered and dribbled against her hoof, making her realize that she had been rubbing it.

"You be a good filly after this and I might even share it once you get your mark," Applejack added.

The very concept would have been appalling to her but just two days ago, even as she was trying to get her school teacher that very same dicking. Even if she wasn't a grown mare yet, she wasn't a little foal anymore. Big Mac was bigger than Applejack, and he absolutely towered over Apple Bloom. The mere thought of ever taking her broth- her father's ginormous dick scared the living-

"Hnggh!" Applejack moaned as she came. Apple Bloom's thigh's clamped together on her hoof in her crotch. Her limbs just went weak as she stumbled against the slick interior of Applejack's inverted uterus. Above her, the ceiling flexed and bulged each time Big Mac fucked downwards into Applejack. Apple Bloom was too weak to move when she heard him grunting above her. Applejack's cervix stretched slightly open as Big Mac's dick throbbed and pumped another thick load of cum inside.

Apple Bloom was coated from head to hoof in his cum. She licked it from her lips, feeling intense satisfaction from it's taste. She was starting to understand Applejack's position regarding his appeal as she greedily consumed the rest of the large pool around her.

"Just like old times?" Applejack said from her hammock, watching Big Mac buck apples out of trees while is semi-hard erection swung underneath him like a veiny, clock pendulum.

"Eeyup," Big Mac replied with almost wistful resentment, doing all of the hard work that weekend.

Inside Applejack's gravid belly, Apple Bloom was finding her space becoming quite cramped. There was no wall that she wasn't touching. She didn't even have room to stretch her legs any longer. Her knees were nearly to her chin. She was hunched over, quite appropriately, in the fetal position. Ironically, inside the safe, protective padding of Applejack's womb, Apple Bloom found it nearly impossible to get comfortable. Her limbs pushed against the sides of her prison.

"Ooh, she's kicking!" Applejack squealed. Big Mac wiped the sweat from his brow and walked over to place his hoof against Applejack's belly, feeling their filly, full of life, moving inside her.

"Don't act like I can't hear you!" Apple Bloom complained. She no longer had to yell to be heard.

"Is my little foal getting cranky again?" Applejack asked. "Another feeding time?"

Big Mac gently stroked Applejack's mane. "I think it's Momma's turn this time," he said.

Apple Bloom was gently rocked back and forth inside Applejack as she sucked Big Mac's dick. Apple Bloom didn't want to admit it, herself, but she was feeling her own hunger pangs. Underlying that was a subtle envy that she couldn't ignore. A feeling that she wanted to be the one sucking his dick. She hoped it was just a feeling bleeding through her link with Applejack.

Applejack's moan of pleasure reverberated throughout her body, all around Apple Bloom. The world turned over around her as Applejack rolled onto her back. Apple Bloom felt the sensation of trying to swallow a big pill, like a really big pill getting stuck in her throat. Applejack's moans turned into guttural grunts and gurgles as Big Mac pushed his dick down her throat until his balls were up against her nose. Apple Bloom felt a strange sensation of her appetite being filled as Big Mac ejaculated straight into Applejack's stomach. This was followed by a dizzy sense, and Big Mac pulled out before Applejack asphyxiated.

Applejack's chunky burp thundered around Apple Bloom.

Apple Bloom didn't feel hungry anymore, but she didn't feel full, either. "How about an actual meal?" she asked.

"I agree!" Applejack said. The world spun around Apple Bloom again as Applejack rolled over to climb out of bed. With less room to be tossed around, Apple Bloom had a rather comfortable ride inside Applejack's belly as she trotted downstairs. Applejack opened the fridge and freezer to make herself a bowl of, "Ice cream and pickles!" she said aloud. Apple Bloom thought it was revolting at first, but quickly found that it was exactly what she was craving.

Applejack made herself a bowl and leaned over the kitchen counter to feed her face with a spoon. Apple Bloom felt a mental sensation of satisfying the craving, but her actual stomach still felt empty. Applejack's body shifted around her.

"Oh, ready again?" Applejack asked.

"Eeyup!" Big Mac said with pride as he mounted Applejack right there at the kitchen counter, pushing his fresh erection deep inside her.

Any objection Apple Bloom might have to them fucking again had vanished. She squirmed around inside Applejack's womb to reposition herself while Big Mac kept thrusting.

Applejack felt a fluttering in her tummy from Apple Bloom's movement. "Ooh, I think somepony is excited." Apple Bloom wasn't listening to anything other than the wet squelching of Big Mac's dick sliding in and out of Applejack's pussy. With little other point of reference, she turned herself to face towards the noise, feeling around in front of her for the now-tiny pucker in the wall. She could feel the dull thumping of the turgid flesh battering the other side, and she waited.

Big Mac's breathing became more rapid and shallow, turning into desperate grunts as he tried to push as deep as he could, restricted to being barely able to get half of his dick inside Applejack now as he started to cum. His flare stretched her cervix and inside, Apple Bloom planted her lips around it. Big Mac grunted with each pulsing throb of his shaft as he pumped load after load straight into Apple Bloom's waiting mouth. She swallowed it just as fast as he could feed it to her.

Even Applejack hummed in satisfaction, feeling her own hunger just as filled now.

When Applejack wasn't laying in her hammock or getting fucked, Apple Bloom was laying in a hammock of her own, swinging from side to side as Applejack's belly swayed under her with every step, rocking her to sleep. Until she was awoken by a frantic shaking of her hurried steps and the sound of running water. Like, a lot of water.

"Are you really that thirsty?" Apple Bloom asked.

"What? No!" Applejack said. "I'm on the toilet, Sugarcube! You were sleeping right on my darn bladder!"

"Ew!"

"Yeah, it wasn't no fun carrying you around the first time either. But at least this time it isn't for eleven months," Applejack groaned.

"You've gotten mighty big," Mac said, watching her from the hallway outside the bathroom.

Applejack eyed his erection as it throbbed underneath him. "You're one to talk." She leaned to the side to get some toilet paper and groaned, trying to navigate around her belly. "Ugh, I can't even reach myself no more!"

"Granny's gonna be home tomorrow night. I suppose it is getting to be about that time," Mac said, helping her.

"Time for what?" Apple Bloom asked.

Applejack rubbed her belly. "Why, for you to be born again, Sugarcube!"

"Oh. Right."

"I thought you'd be more excited to be done with your time-out," Applejack said.

"No, I am. I just..." Apple Bloom trailed off, readjusting herself inside Applejack's womb. She had wanted so badly to get herself free. And it had become undoubtedly cramped. And yet, the thought of actually leaving felt surprisingly melancholy. "It's just that this has been... nice. Strange, but nice. Learning about you and Mac, er, Dad, I guess. Knowing that I still have my parents."

Applejack slumped into her bed and laid on her side, rubbing her belly. "This has been nice for me too," she said. "I'm sorry about what I said earlier, about it being no fun carrying you around. Honestly, being pregnant is physically uncomfortable. But having you back inside me, feeling you grow, has just been so..." Applejack felt herself getting misty. "I love you so much, Bloom. You've always been my little filly. Having you was the best darn mistake I ever made!"

Big Mac held Applejack's hoof. "We made. Together."

"I'm so glad we could finally tell you the truth about us. About you."

Apple Bloom didn't need her umbilical cord to feel their love. "I almost don't want to leave."

Big Mac rubbed his cheek against Applejack's stretched belly. "You do look so beautiful like this, carrying our little foal inside you."

Applejack smiled. "Part of me would love to just keep you in there forever Bloom, keep you safe and sound. But if you get much bigger, you're gonna pop me open like a dang watermelon! So we gotta get you out."

"How?"

"The old fashioned way," Applejack sighed. "But to get that started..." She trailed off and looked at Big Mac. He took the last potion vial out of the kit that Zecora had given them. Applejack nodded and he drank it. He felt his scrotum start to tingle, and Applejack could see his balls visibly swell larger. They had both rehearsed the entire process from start to finish. She laid back on the bed and waited for what was to come next as he spread her legs for her.

Big Mac was in no rush for this chapter of their lives to end again so quickly. His nose nuzzled against her very full teats, swollen with life-nourishing milk. He was sorely tempted to indulge himself, but he knew it was for the coming newborn foal. He ventured lower to Applejack swollen pussy, taking long, deep licks inside her, savoring his sister's pregnant flavor one last time, taking great efforts to commit it to his memory. He would cherish it forever.

Applejack panted and wheezed, but less from pleasure, and more from the pressure inside her. "Mac, come on," she pleaded. Big Mac was many things, but selfish least of all. Nothing could make him deny his sister's plea.

Even if that was how they got into this predicament in the first place.

He reared up and gently mounted her, pushing the tip of his dick inside her very wet pussy. With Apple Bloom taking up most of Applejack's abdomen, barely a third of his shaft was inside her before he bumped into her cervix. Apple Bloom had lost all sense of up or down inside Applejack's womb. All she could feel was an insistent knocking behind her.

Applejack knew what was coming next. She gripped the bedsheets, and braced herself. Big Mac looked at her with worried eyes, but she just nodded with determination.

The knocking behind Apple Bloom came harder. The strong, muscular walls of Applejack's uterus flexed and bowed inwards. Apple Bloom could feel Applejack's cervix begin to stretch and dilate more each time. "What the hay!?" With one last firm push, the tip of Big Mac's dick popped inside Applejack cervix. Applejack stifled her yelp from the sudden discomfort but remained steadfast, nodding for him to keep going.

Apple Bloom panicked as what felt like the seat of a bar stool was suddenly shoved against her whole backside. There was hardly no room at all, but she still scrambled to move herself out of the way as Mac pushed more of himself inside. His massive girth moved up between Apple Bloom's legs against her belly. Applejack groaned and grunted feeling her being stretched even more.

Big Mac kept going until he was able to get his heavy balls resting against her ass. He sighed once he got full length back inside his sister again. "Ah, finally!"

Apple Bloom was now sharing her already-tiny apartment with a massive, veiny, tree trunk, with his tip pushed up against her chin. Applejack's breathing was coming fast and shallow with hardly enough room left inside her for her lungs. "Don't. Dawdle. Now," she panted.

Big Mac took one last look at her beautiful, pregnant body and nodded. He started thrusting gently, but with intention to finish as fast as he could. He would not prolong her discomfort.

Apple Bloom's concern only intensified as his dick thrusted inside along her torso. Even if she knew what to expect, nothing could have actually prepared her for the reality of what was actually about to happen once his tip flared in front of her.

Big Mac felt himself go past the point of no return. Every orgasm he had ever had in his entire life flashed before his eyes. From his very first wet dream, to when his hoof discovered himself. To losing his virginity with his own sister, and every time they made love since then. To the forceful ejaculation of Apple Bloom back inside Applejack's womb, and all her feedings in the past few days. Nothing even came close to this.

The effects of the potion swirled around, and within his balls, sending their production into overdrive. The sheer volume of cum shooting up through his dick almost hurt to stretch his dick around. What was once a quick blast of stallion yogurt turned into a continuous firehose of semen blasting Apple Bloom in the face. The tight seal of Applejack's cervix gripping his dick let his sister feel just how hard his dick was throbbing. And it also gave his torrent of cum no exit as it quickly filled what little space was left inside her womb. Apple Bloom held her breath, but was quickly reminded that she still didn't need to breathe.

Even with the rest of the space filled, he didn't stop cumming. The pressure actually started to push his dick back out until only the sheer girth of his flare remained stuck. Applejack moaned as her was uterus stretched to its absolute limit by the time he finished. The bit of extra space let Apple Bloom awkwardly turned herself around inside. Driven by instinct, her cozy comfort had been replaced with a frightful claustrophobia. Her legs pushed against the top of Applejack's womb and the top of her head pushed against Big Mac's dick.

The bit of extra pressure was finally enough to get him dislodged until it was Apple Bloom's head plugging the exit. The potion mixed into Big Mac's semen swirled around inside Applejack's bloated womb, being absorbed into her bloodstream. Applejack clutched her belly and groaned as her contractions started. Her body's natural instincts took over, beginning the process to push her foal out.

The walls around Apple Bloom's body squeezed her hard, downward against the tight exit of her cervix. Each squeeze, each push got her a little further as Applejack's cervix stretched open just a bit more. Once that widest part of her head was through, there was just the matter of her shoulders, and before long, she was nearly half way there. She felt Big Mac's dick against the top of her head and suddenly she was shoved back up inside Applejack's womb again.

Applejack grunted from having the wind literally knocked out of her. "The hay is wrong with you!?" Applejack yelled at Big Mac.

He rubbed his hoof over her belly one last time. "Sorry. I just wasn't ready for you to be done being pregnant," he said, before pulling himself out completely.

"A real considerate mid-wife you are!" she groaned, feeling her hard labor undone in one thrust. "Argh! Get her out of me!" Applejack shifted herself to the edge of the bed and rolled over to put her legs on the floor. She pushed again, hoping gravity would help this time. Thoroughly stretched from the first time, she was able to push Apple Bloom out a bit easier. Apple Bloom's head was out of her womb again, squeezed on all sides by her powerful vaginal muscles.

Applejack felt Big Mac on top of her back. "The hay are you doing now!?"

"This'll help," he said, pressing the tip of his dick against her anus.

"How in tarnation is that supposed to-!" her voice was cut off as he pushed his dick inside her ponut.

"Too much potion," he grunted. "Nuts too full."

They never regretted having Apple Bloom. But one inbred foal was enough. There was no sense in rolling the dice with another. As such, Applejack had become quite used to taking his full length up her tail pipe. But her pelvis was already quite crowded.

Through the thin divide, Apple Bloom could feel the girth of Big Mac's dick rubbing against her face as he pushed the full length of it back and forth up inside Applejack's rectum. He reached around and played with her clitoris as he did. Another contraction rocked through Applejack's body and her every muscle squeezed together to push Apple Bloom out a little more.

"Land's sake!" Applejack screamed. The symphony of pleasure, pain, and pressure became a jumbled mess of sensations clouding her mind of any rational thought beyond 'push'. With the next contraction, the top of Apple Bloom's head felt a cool breeze.

"I think she's crowning," Mac said as he continued to plunge his dick deep inside Applejack's asshole. More of her head emerged with the next push and Apple Bloom blinked in the harsh light of the outside world... and then with each time Big Mac's balls smacked her forehead. She winced and tried to look away, squirming inside Applejack's stretched birth canal to turn herself over.

"Bloom! What are you doing to me!?" Applejack moaned before pushing again.

Facing towards the floor now, she could see Big Mac's hoof expertly playing with Applejack's clit. With the next push Apple Bloom was able to get her first breath of fresh air.

Big Mac grunted above them and hilted himself deep inside Applejack's ass as he unloaded yet again, flooding her colon with cum. Apple Bloom felt the pressure inside built even higher and Applejack's pussy quiver around her, squirting her in the face with her mare cum. The rush of extra lubrication helped Applejack for the final push, sending Apple Bloom tumbling out onto the carpet followed by the deluge of her parents' collective cum gushing out of Applejack's birth canal.

She watched Big Mac slowly pull out of Applejack. Her strong ponut prevented any worse mess while his erection finally retreated back into his sheath. Applejack rolled over onto her back and breathed a sigh of relief, seeing that her massive belly had finally returned to her normal proportions.

Apple Bloom didn't understand why, but she started to wail.

"Oh, bring her here!" Applejack said. Big Mac picked up Apple Bloom and brought her to Applejack's waiting hooves. "There there. It's okay little one. It's gonna be okay."

"Hungry?" Big Mac asked.

"She must be," Applejack said, holding Apple Bloom to her swollen teats. As soon as the nipple touched her lips, Apple Bloom started to suckle. "There there. You've had a long day." As soon as she emptied one, she went right to the other, draining them both of her milk. "That's the way, little Bloom. Help you grow big and strong." Applejack stroked her mane until she fell asleep on her chest.

~

Apple Bloom awoke with a start. It felt like a part of herself had been severed, like she had just had a limb cut off. She looked at Applejack. Startled awake from her own nap, Applejack looked back at her just as worried. Apple Bloom looked at her umbilical cord, following along it from her belly button all the way back between Applejack's legs, into her marehood. With barely a tug, the remaining length freely slid out of Applejack. The cord in her hoof withered away and it fell from her belly button.

"No, no no!" Apple Bloom cried, trying to spread open Applejack's vagina with her hooves. But there was no way. The potion's magic in Applejack's milk had Apple Bloom nearly back to her original size in the course of her nap. It was over. She was out. The way was shut. And there was no going back inside to that lost paradise of her mother's womb.

Apple Bloom now understood why newborn foals cried. Applejack pulled her into a hug.

Applejack directed her to her full teats. "I've got one last feeding for you before these go away. Zecora said you'll be back to full size by tomorrow morning."

Apple Bloom started to suckle her mother's milk again. Her mother's milk. She looked up at Applejack. "Mommy..."

Applejack had waited her whole life to hear that.

She hugged her harder. "Yeah. That's right. We can't be telling everypony that, okay? But you can call me Mommy now." Apple Bloom nodded.

Big Mac returned from taking a shower. "She awake?"

Apple Bloom looked at him. "Daddy?"

Big Mac's erection slapped his belly.

"No!" Applejack scolded. "Only I get to call him Daddy."
