It was a beautiful afternoon in ponyville, the calm warm sun shining down as a stallion can be seen fishing on the dock. it was ‘sort of his hobby. The small house with a hay thatch roof may look primitive, but the land of magical pastel ponies had its tricks, inside a mare paced as she tried to make a decision, hoping her mother could help…

Rarity was nervous. She had come over to consult her mother on a better way to keep her sister safe from the other preds in town. Before now she had resorted to just swallowing her whole like some petite pastry. She was asking her mother what she could do differently, worried she had hurt her sister’s young mind by eating her every now and then. it’s nice having her over more often but it’s not getting easier. The mare thought, glancing back at her sibling busy drawing at the kitchen table seemingly laser-focused. the mare really hoped she hadn't harmed her...

“I can't keep swallowing her and the spells don't always work,” the mare said, expressing her worries to the elder as she walked into the living room.

“I know, but I think I have a solution to that problem,” Cookie Crumbles said. The mare that had taught Rarity everything sitting down to enjoy the visit.

“Oh?” Rarity listened curiously, sitting down as well… the couch comfy but doing nothing to quell her nerves

“Rarity, it may be hard to think back to for you, but do you remember when you were really little, and sometimes you got scared?” the older mare asked.

Rarity nodded. “Do you remember where you went when you were scared?” Cookie Crumbles inquired.

Rarity thought long and hard, then a memory came back to her. She gasped. “Mother! I can't just walk up to her and... Are you saying I should…?” Rarity was unable to finish her sentence as she thought about it, her face turning rose.

Cookie Crumbles chuckled and nodded, “I believe she won’t mind much if you can explain it to her.” the mare stated, smiling and peering into the dining room by leaning over a moment…

Rarity chuckled nervously, then sighed, unsure what to do. “But… but what if she says no? I can't just force it on her, can I?”

Cookie Crumbles chuckled. ”oh, darling! You need to relax! If she were afraid of you, she would have run away after she found out you eat ponies by now, I know she trusts you, and I don’t think she will refuse. Granted, the situation will be odd for her. But I think, if she’s anything like you, she’ll enjoy it,” Cookie Crumbles told her daughter.

Rarity blushed even more uneasy at that, “but mother I’ve never done it to guh um protect anyone before” the mare broke into a whisper on the last part, her mother only chuckled more.

“Oh relax you’re my daughter and you pack just as many away as I do, I'm certain you can do it, now push that thought down and go get her” the mare stated, remembering when she used to hide her daughter away.

Rarity took a deep breath, thinking long and hard on this. “Alright but what if she says no?” the mare asked uncertainty…

Cookie crumbles, chuckled. “With how much you were fine with it, I'm sure she’ll love it as much as you did,” the elder smiled, patting her belly... “It's still open if you ever feel the need”

“Mother!” Rarity blushed as she lost her tone before relaxing, the mare paused looking toward the dining room she got up.., “I hope you're right...” the mare sighed looking back at her mother.

“Have I ever not been there for you... I'll watch in case you need help” the elder started, getting up as well, her eldest daughter blushing even redder…

Rarity tried to smile and hugged her mother “um hehe” she stammered nervously before she walked back over to her sister, who was still drawing.

Cookie crumbles followed behind and waited to see if her daughter would need help...

As rarity came in she found her sister was still focused on her scribbles. “Sweetie, darling?” began Rarity as she put an easy explanation together.

“Huh?” Sweetie looked up from her page and smiled nervously. “Do you want to swallow me again? It’s ok, sis I trust you, and as long as you keep your word, you can eat me.” The filly blushed as she squirmed in her seat.

“No, no, Darling. I want to try something different and um...”. began Rarity as she struggled to piece together a simple explanation.

Sweetie’s smile vanished. “Rarity?” she whimpered. To her, she thought her sister wanted her like the other preds did. knowing after it was explained that her sister had ‘cravings’. She didn't want to be digested as she expressed this without needing to say so.

Rarity caught her sister’s reaction mid-thought and looked up to notice her sister shrink back with a hint of fear and was quick to correct herself. “Oh, no, no! I mean I want to have you in a much more special place! In my, um my hehe” the young mare tried before realizing she couldn't explain it unless she gave her a bit of the talk.

Sweetie blinked. she noticed her sister was speaking as if she was uncomfortable, the filly had only learned one kind of vore thus far and her sister was making her mind race why she loves having me as a snack? What does she mean! I only know one way in, was there more? She seems so uncomfortable does she want to… keep me!

Rarity stammered a moment “Swee~ sweetie, no, no, Darling. That's not what I meant. No, there is a special place inside my tummy called my womb. Now, to get there, I don’t swallow you like you would think.” The mare blushed breaking her sibling from her thoughts as she said this.

Sweetie’s eyebrow went up in mild confusion as her mind froze a moment, the jolting from her deep thoughts letting her speak again, “Oh, um, ok. Is it safe?” the filly asked innocently, not yet understanding what she would be doing.

Rarity nodded as she began to explain in more detail; her sister smiling innocently at her as she saw the drawing the filly had been working on, “Yes, much safer but, Oh, Darling what’s this?” began Rarity only to realize her sister had made a vore drawing.

Sweetie blushed, trying to hide the picture at first before sighing. “It's nothing; just me in your belly like you’ve been doing. Hehe… um, what’s so different if you send me to your womb? Where is it?” the filly inquired innocently, explaining that the last time she was a snack was still on her mind.

Rarity blushed trying to find the simplest way to explain. “Well, dear, there is a special place inside my tummy called my womb. Now, to get there, I don’t swallow you as you would think.” the mare said. Seeing this only raised more questions in her sibling’s mind, she sat down and spread her legs. “You see this, Dear. I know this is sudden, but that's where you came from,” the mare said as she laid down, and situated herself in front of the filly, blushing with her sibling. “You see this here?” Rarity said as she pointed to her nether-regions and used her magic to spread it as far open as she could; a gaping vagina in full view.

Sweetie turned away and blushed, looking down at her own small folds. Just what in Tartarus did her sister want if that was involved? “RaRiTY?” the filly whined, displeased with her sister’s show of indecent exposure.

Rarity Blushed in understanding as she sat back up, letting her folds close as they winked wetly from the brief stimulation. ”Sorry, Darling, but that’s the entrance to my womb. If you were to crawl in there, I could keep you safe without having to swallow you. I would just sit down and you would slip right into my womb. You would be warm, snug, and wouldn’t have to worry about other ponies trying to eat you when I’m not looking,” Rarity explained.

Sweetie started to giggle with a mix of embarrassment and nervous energy. A rose blush on her face. “hehe Rarity, that's nuts! , um. I hmm…” the filly began as gears visibly turned in her head. “Sigh. Ok, so you're saying I came out of my mother’s pee hole?” the filly finished in a perturbed voice.

Rarity felt like she would rather pass out than give this talk, but pushed forward. “Uh, hehe. Yes. I mean, no! you came out of mothers! vagina er oh dear. sigh let's start over,” the mare answered before correcting herself and going into detail. “Let me clear things up. Yes, that's where we pee, but it's also where foals come from,” the mare finished as she blushed, rolling her eyes at how badly she wished Cheerilee had given this talk rather than her.

Sweetie didn't want to talk about it anymore and tried to say so. “Rarity, can you just skip the how and tell me what happens?” she asked, hoping to get things over with.

Rarity couldn't be happier to oblige. “Oh, of course, dear. You see, what happens is that I'm going to do something called unbirthing Or rather, put you in my oven for lack of a better term,” the mare let out, holding her composure.

Sweetie’s face scrunched up in an expression only a filly could manage as gears visibly turned again. “Um, ok. So long as you think it's safe I guess it couldn't hurt to give it a try?” The filly seemed unsure as she said that, but did, in fact, trust her sister with her life as she got up and hugged her, ready to do as she commanded.

Rarity let out an excited squee, only to blush and hug back. “Of course, darling. I wouldn’t force it on you; that's why I wanted to explain,” the mare said as her folds tingled in anticipation.

Sweetie smiled, then frowned. “Well, when are you going to uh, unbirth me?” the filly asked, sounding impatient as the word left her lips with the sound of unfamiliarity.

Rarity giggled as she put a hoof on her sibling’s shoulder. “How about now? just hold still and help me get you in, It's not as easy as swallowing you dearly,” the mare said as she turned around.

Sweetie’s mind reeled for a moment as she realized she would be going up to a place where pee normally came from but pushed the thought out as she blushed. “Rarity?” the filly let out, nervously unsure of herself as she spoke, Rarity turned around and flagged up her tail, her mare bits in full view. Sweetie could only blush and stammer at the view even as it looked to get closer. She could smell Rarity’s scent get stronger until the winking slit squished against her muzzle. She blinked as she thought about backing away from the folds.

“Are you ready, Dear?” asked Rarity as she blushed, licking her lips as she cleared her mind the best she could from any perverted thoughts. This wouldn't be like the other times she had made a snack out of a handsome stallion. This would be to keep her sister in a safer space within her warm, lithe body. Rarity waited as she felt a tongue curiously extend into her folds.

Sweetie blushed. Why did her sister’s pee hole taste pleasant? But before she could think further, her sister had asked her a question. “Uh, I guess?” the filly let out, not all too confident in her answer. Before she could get a reply, Sweetie found her muzzle slipping between the soft lips of her sister’s pussy.

Rarity moaned as her sister’s muzzle slipped in. “Shush! Once your head is in, Dear, I’ll do the rest,” the mare said as she began to sit down.

Sweetie blushed as she was left in a warm dark tunnel. the fold slipping over her muzzled and face as if she were a living dildo. The filly listened as her sister’s voice cut out too muffled sounds when her ears were forced to lay flat against her skull. The wonder and slight worry of what was happening was nothing compared to the strange feeling as the filly felt her own folds twitch.

Rarity cooed as she looked down her chest and watched her belly to see the bulge her sibling was making in her abdomen. She patted it with her hoof as she almost lost balance. “That's a good filly, hmm. *Pant* Oh, Darling, I’m going to enjoy having you in there!” the mare giggled with excitement, delighted her sister had agreed.

Sweetie wiggled as she was pushed against a restricted nub of flesh. A scent of arousal she had never noticed before assaulted her nostrils as she slipped inside surprisingly easily. To her, it was dark, so she lit her hor, finding walls of soft spongy flesh pressed against her as she stared at a strange fleshy nub that looked like an internal butthole.

Rarity slowly squatted down onto Sweetie, forcing more of the smaller pony inside. The velvety texture of the accommodating passage rubbed and massaged against Sweetie as if she were an actual cock shoved inside the mare, which only helped pull the smaller pony inside. Or that was the direction Rarity forced her mind to go, refusing to let her perversion taint they’re relationship.

Sweetie was confused, her young mind not able to understand the feelings of arousal as her sister guided her hooves to join her chest as they slipped in together inside Rarity’s passage. The filly tried to push them out to get comfortable, but only managed to wedge herself tighter inside and bring more pleasure to the larger mare. She felt the passage spasm around her and could feel her sister’s clit winking against her underbelly as she slipped even further in.

Rarity struggled as she tried to relax her cervix to let her sister in. “Oh. pant... Come on! Ahh,” the mare let out just as the gateway opened and her sides slipped forward and up.

Sweetie squirmed as her sister shoved harder. She was about to complain when the nub gave way and she found herself in a much softer place, her body beginning to slide in more easily. An odd pleasure from that brought a smile to Sweetie’s face as the tight space gave way to one with more room.

Rarity moaned, unable to hold her arousal any more as her vagina hungrily clenched at her sister’s small form. “Oh! pant Almost there Darling! Hm mngh, ahh! So warm!” the mare giggled panting as she began to slide over her sister and sit down.

Sweetie grunted as the walls around her barrel clenched hard around her and massaged her with more vigor, pushing her harder against the top of her sister’s womb as she decided to help and try and curl up. The juices around her increased in volume and increased again when she slipped in further. Though muffled, Sweetie could just make out a very pleased sounding moan from Rarity. Sweetie smiled. Knowing her sister was happy made her happy.

Rarity was almost to the floor now. As her belly was very large, a lumpy mass shaped like a small foal squirmed as if to get comfortable. “Easy, dear. I'm almost done,” the mare said as she used her magic to hold her sister’s back legs against what remained of her sibling’s belly.

Sweetie groaned as the passage around her lower belly clenched tightly and her sister sat down on her before she was forced inside the womb to curl up, She squeaked as the sudden jolt into the womb was unexpected.

Rarity sighed in bliss as she enjoyed the bulge forming in her belly. The mare used her magic to rub on the bulge, a small smile forming on her face as she felt her body recover...

....

“Very well done, dear. You make me jealous, seeing you so full and happy,” said cookie Crumbles, her proud voice startling her panting daughter.

Rarity looked up, It was as if her mother had vanished, only to reappear, having forgotten she was there. Rarity rolled her eyes as she felt things take hold. She could feel her body accept her sister as an umbilical cord attached to her little sister and brought their hearts into sync. Rarity was just happy there weren't any complications and that her mother hadn't forced her to recycle her own sister into her own foal.

Sweetie felt strange as she felt something bite her belly, but still trusted her sister as she felt suddenly exhausted and fell asleep before she could complain. The filly would stay till her sister wanted to hold her again, but until then, the filly was the older mare’s baby bump.

Cookie crumbles chuckled as Rarity seems to not get it, too caught up in a feeling she knew a lot more about. “What oh don't start I am not fat!” the now foal burdened mare and daughter retorted, making cookie crumbles giggle more.

“You don't know do you, Rarity darling it’s your sister’s first unbirthday! I'm so proud, of both of my young preds” the elder mare giggled, moving in to hug and enjoy teasing her daughter for the next few days….
