Sunset Shimmer was walking down the sidewalk, on her way to a slumber party hosted at Fluttershy’s home (at the meek girl’s request, oddly enough.) She was clad in her usual purple shirt, black jacket, and orange skirt, and carried her backpack on her back, though it was somewhat heavier than usual due to holding some materials for the party. She sighed lightly in relief finally when she came into visual range of the house and sped up her pace a little.

When she arrived at the door to the house, she reached an arm out and knocked on it thrice, then quickly returned it to her backpack strap to help relieve some of the strain from having walked around with it for a while. A few seconds passed before the door was tentatively opened and Fluttershy was seen on the other side, looking a little scared.

“Oh, hi, Sunset,” The shy girl said, barely audible over the arguing in the background between Rainbow Dash and Applejack.

“Uh, hi,” Sunset replied before averting her gaze to the arguing girls sitting on the couch and lightly grimaced. The pink-haired girl in front of her moved to the side to allow her entrance, which was quickly taken as she addressed the cyan and orange-skinned girls. “I swear, it seems like half the time I come across the two of you together, you’re fighting in some way.”

Dash glanced at the kournikova-coloured girl and quickly responded, “Yeah, I know-”

“Clearly,” Sunset interjected as she set her backpack down on the floor. “While I respect your right to compete with each other, right now you’re being pretty loud,” She added while looking sternly at the other girl.

The rainbow-haired girl looked back at her and opened her mouth as if to respond, but shut it when she saw Fluttershy’s worried expression. “R-right, sorry,” She replied apologetically.

A light scoff was heard from Twilight who was sitting on a armchair near the couch and holding a book. “I’m not even sure why you try at this point, Sunset. I mean, sure, we can stop it now, but it never seems to stick, you know?” She said in a mildly demeaning manner.

“Sorry,” Applejack responded, mostly aimed at Fluttershy.

“Sorry isn’t going to do anything,” Sunset bluntly replied. “You need to actually back it up.”

“Um, I’m sure they’re trying...” Fluttershy meekly interjected, still standing near the door.

“Oh, I’m not all too sure about that,” Rarity responded. “While I don’t mean to demean your optimism, darling, I doubt everything is going to turn out the way we wish.”

Rainbow Dash sighed heavily at this and reclined deeply into the couch, then opened her mouth as if to reply, but was cut off by a pair of loud thumps at the door. Fluttershy jumped and squeaked in fear at the noise, but inhaled and exhaled deeply to calm herself before reaching a hand to the handle and opening the door.

“Hi, Fluttershy!” A very excited Pinkie Pie said while she stood at the door, balancing multiple boxes of pastries on her hands and head.

“Hi, Pinkie,” The yellow skinned girl replied, before moving out of the way to allow her friend to nearly bound her way into the house, somehow keeping the box stacks stable. She then stood near the coffee table at the center of the room, a huge grin plastered on her face as she looked at the other girls in the room staring at her with light amusement and confusion on their faces.

“Wait a minute,” Twilight said, drawing everyone’s attention to her. “How did you knock on the door?” She asked, utterly baffled.

Pinkie’s smile became even bigger for a few moments before she gleefully responded, “With my booty!”

The other girls’ then stared at the energetic girl again, this time with a heavy mix of amusement, awe, and confusion.

“You... knocked on a door... with your ass?” Rainbow Dash questioned, looking like she was about to break out into extreme laughter.

“Yeparooni!” Pinkie replied, hopping up and down a little.

Twilight opened her mouth to respond, but kept it open as no words came for multiple seconds before she eventually sighed and covered her face with a hand in defeat.

The assorted snacks were set on the coffee table and the girls sat around it on various seats, all wearing in their usual pajamas while watching the cheesy horror movie Rainbow Dash picked with differing emotions; Fluttershy cowering into the side of slightly grimacing Rarity, Twilight occasionally switching her gaze between it and her book, Pinkie being utterly enthralled and overreacting at multiple points, and the others just watching with light amusement.

After the movie had droned on for a while, Fluttershy began to shift around a bit more, feeling a light pain in her chest. She then slowly pulled away from Rarity to get up.

“Is everything alright, darling?” The white-skinned girl asked concernedly.

“Um, yeah,” The shy girl replied quietly. “I just need to use the bathroom,” She elaborated as she stood up and briskly walked over to and up the stairs, drawing a few glances from some of the other girls.

Rainbow Dash chuckled, then said in a lightly amused manner, “I didn’t expect this movie to literally scare the piss out of her.”

“The movie has been going on for quite some time, I imagine it’s likely that she needed to use via more... natural reasons,” Rarity responded, sounding a little peeved.

“I was just joking, alright? Chill,” The athletic girl replied, holding her hands in front of her defensively.

“Could of at least tried to sound sarcastic,” Sunset said flatly from beside her.

“Hey-”

“SSSHHHHHHHHHHH!!” Pinkie loudly interjected, facing the other girls and holding a finger to her lips to indicate silence, to which they obliged.

The rest of the movie was watched in relative silence from the girls, and when it ended and the credits rolled, Sunset looked over to where Fluttershy was previously sitting and noticed she still wasn’t back.

“Is Fluttershy still using the bathroom?” She asked, a tad concerned.

“It seems so,” Rarity answered while looking to the empty seat beside her.

“Hmm,” Sunset responded before getting up. “I’m gonna go check on her,” She added while going over to the stairs, then went up them. She next traversed the upstairs hallway to the bathroom, but stopped upon hearing some quiet noises emanating from one of the other rooms. She slowly walked over to the door of said other room and attempted to discern what was happening on the other side, but failed.

She took hold of the door handle and turned it, then opened the door slightly and called through the crack, “Fluttershy? Are you in there?”

She next heard some a gasp and some quick shuffling through the door, followed by what sounded like a door opening, then slamming shut. “Uh, Fluttershy? You alright?” She said as she opened the door farther and walked into a bedroom, and from the bright coloring and tons of stuffed animals, it was clear that it was Fluttershy’s. She made note of the disheveled bed and clothes strewn about the floor as she looked around the room before spotting a closet.

Sunset tentatively made her way over to the closet and grabbed the handle, then swallowed to mentally prepare for what she may see in there, and opened the door, leaving her to stand face-to-face with Trixie.

“Sunset!” Trixie cried in bewilderment and shock.

“Trixie!” The other girl yelled back in a similar tone.

“What are you doing here?!”

“Checking on my friend! What are you doing here?!”

“Trixie was-” She noticeably hesitated while a faint red tinted her cheeks, “-talking with her friend!”

Sunset squinted in suspicion at the other girl. “‘Talking’?” She questioned, her voice quieting down somewhat.

“Um,” Trixie gulped as her cheeks flushed even brighter, “Y-yeah, talking...” She finished, the kournikova-skinned girl staring at her, looking completely unamused. The usually vainglorious girl sighed in defeat before she admitted, “Okay, fine. Trixie was...” She paused to look for a decent way to put it, “playing with her mommy.”

The yellow and scarlet-haired girl looked at her in utter bewilderment and asked, “‘Mommy’?”

The frost-haired girl’s blush turned crimson red as she covered her face in shame at her accidental admission, leaving the other girl to stare at her, completely baffled as to how Fluttershy could’ve possibly consummated such a relationship with Trixie of all people. She was pulled out of her perplexed stupor, however, when a short squeak was heard from the bedroom door.

“Sunset!” Fluttershy squealed, looking at the other girl in light shock and embarrassment.

“Fluttershy!” Sunset responded, refocusing her confusion at her. “Do you mind explaining why Trixie is in your bedroom?” She asked in a lightly stern manner.

“Oh, um,” The shy girl started, her already existing blush growing brighter. “W-well, we...” She stuttered, clearly embarrassed.

“Fluttershy,” The orange-skinned girl replied calmly, drawing the other to look at her with with her face half covered by her hair. “I’m not mad that you have a girlfriend, just confused as to why it’s Trixie,” She said, then lightly blushed as she remembered what the girl referenced her girlfriend as. “And... a little as to the nature of your relationship.”

“O-oh, w-well,” Fluttershy responded, her blush deepening even further, “Trixie d-didn’t really have any friends, s-so I became hers... Um, and then, w-we, umm...”

“Had sex?” Sunset finished inquisitively.

The other girl shyly nodded and quietly replied, “Um, y-yes, and I’m trying to help her become nicer to others...”

“Oh, okay,” The primrose and scarlet-haired girl responded, her tone more friendly now, but quickly dipped back into confusion. “And you haven’t told us this, why?”

“Uh, well, I kind of thought you girls wouldn’t really like me being around Trixie...” The shy girl replied, sounding a little scared and hesitant.

“Hey, no, it’s alright,” Sunset said comfortingly as she approached the other girl. “I mean, if you were just having sex with Trixie, then yeah, we probably would feel a little betrayed. But since you’re actually trying to help her,” She paused as she arrived in front of the yellow-skinned girl, “Then you’re alright,” She finished, but quickly added, “More than alright, that’s actually pretty admirable!”

Fluttershy started to blush now moreso from the compliment as she quietly replied, “Um, t-thank you...” She next slowly sidestepped the other girl and walked over to the open closet to see Trixie still inside, who looked rather scared when she saw her girlfriend, and quickly hugged her.

“Shhhh, it’s okay, Mommy’s here...” The usually shy girl said comfortingly while she petted the other girl’s back, continuing to do so for more than a minute before she looked back at the kournikova-skinned girl still standing near the door, now rubbing a hand on her forehead. “Um, Sunset?” She asked with mild concern.

“I-it’s alright, I understand,” Sunset responded, rather embarrassed with the encounter, before putting her hand back at her side. “Um, do you want me to tell the others?” She questioned, her tone sounding more casual.

“N-no,” The pink-haired girl meekly replied, “I’ll do it, just, um, when I’m more comfortable with it.” She then started to move backwards slowly to the bed and sat down on it while still hugging Trixie.

The other girl shook her head lightly to clear mental images of what the other two would be doing together before responding, “Uh, alright. Well, I’m gonna go, just come out soon, the other girls are a little worried.” She heard a quiet ‘okay’ and muffled ‘mm-hm’ from the other girls as she turned around and headed for the door, then walked though it and cast a wayward glance back at the others that quickly evolved into a bewildered stare when she saw what they were doing; notably, the sapphire-skinned girl suckling on one of Fluttershy’s nipples.

She would’ve left if it weren’t for her quick re-examination of the girls, where she noticed a large belly on Trixie which made her look a few months pregnant, and definitely wasn’t there a couple days ago. She stood baffled at it before reassessing the previously thought to be sexual position they were in, coming to only one logical conclusion.

“I-is she getting milk from that?” Sunset asked in an utterly vexed tone while meekly pointing at the shy girl’s huge breasts.

“Um, yes,” Fluttershy replied calmly, making the orange-skinned girl sigh with bewilderment and putting her off-balance for her next statement; “Do you want some?”

The question made the usually rather confident girl completely stop moving and blush madly out of embarrassment while she lost herself in thought. Nearly a minute passed before she looked back at the other girls and defeatedly replied, “Oh, why the hell not?”

Sunset closed the door before walking over to the pink-haired girl, crouching down slightly when she arrived to put her mouth level with the breast not currently being milked by Trixie. She next tentatively moved her head forward and stuck her tongue out, eventually having it touch the large pink nipple present on her friend’s massive primrose boob.

She started sucking lightly, just to get a taste of the milk, and found the taste to be absolutely glorious. She never tasted anything like this in her life! And that was saying something, given how she had two different worlds of experience, one of which she spent a lot of time an a literal royal palace. The taste was so good, she just had to have more, so she quickly took her hands and wrapped them around the huge mammary in front of her, suckling harder on it and she gripped and kneaded its enormity.

She was lost in the irresistible warmth and flavour of the milk, slowly closing her eyes as she delved into a trance in which it was the only thing that mattered. Her sucks became deeper as time flew by, its relevance now meaningless as the milk began figuratively began to fill her mind and literally began to fill her belly. She put a hand on her slowly expanding tummy, feeling it grow as it filled with more milk, completely null to any sense of any discomfort it may bring.

Unfortunately, Sunset’s lack of breath eventually got the better of her, making her pull off the nipple with a wet ‘pop’. She pulled away from her friend and sat down on the floor in front of her, slowly rubbing her rather large belly.

“Oh, wow,” She groaned in discomfort and amazement as she looked down at her multiple-month-pregnant-looking belly. “I drank so much,” She stated, looking up at the other girls she now remembered were in the room.

“Mm-hm,” Fluttershy nodded while looking down at the kournikova-skinned girl with a motherly smile, while Trixie looked pleasantly drowsy, if a little amused, as she rested her head on the breast she was nursing from previously. The normally shy girl then opened her arms wide as if to ask for a hug, which made the sitting-down girl crack a light grin before getting up to her feet. She groaned as she stretched her limbs, relieving herself from the light cramps she got while nursing from her friend, then walked a couple steps forward and wrapped her arms around the busty girl.

The first sensation Sunset got from the hug was pleasant softness, but was quickly replaced as the other girl squeezed her arms tightly around her, and lifted her up.

“Woah, what are you doing?” The scarlet and golden-haired girl asked in a mix of worry and shock as her belly was placed on the yellow girl’s shoulder. Her question was quickly answered however, when Fluttershy began patting her back and Trixie giggled like a child, making the usually confident girl blush madly with embarrassment. After a few seconds, she opened her mouth to protest, but a loud belch came out instead.

“Really?” She responded in an defeated tone, making the sapphire-coloured girl below her break out into full-on laughter.

A few minutes passed during which the pink-haired girl forced a few more belches from Sunset before she finally let the now flaming-cheeked girl down to her feet, allowing her to back up a few steps and glance awkwardly around the room as Trixie's laughing died down. “Um, t-thank you, Fluttershy,” The light-orange girl finally said. “Thank you, for the, uh, milk...”

“You’re welcome!” Fluttershy beamed, looking at the other girl with an ecstatic smile. “Oh, and don't be afraid to to ask for more of that whenever you like! Just, um,” She added and gained a bit of a blush herself, “Be discreet about it.”

“R-right, of course,” The kournikova-skinned girl replied before biting her lip and looking at the other girl hesitantly. “Um... I’m just gonna go now...” She meekly added as she slowly walked over to the bedroom door, casting another wayward glance back at the others before closing it.

Author's Note

It may seem odd that there is no Chapter 3B, and that’s completely intentional. There will likely be an unequal amount of stories on each side, and there will also be other chapters that are side specific, the main reason being to keep them lined up, so that character counterparts will end up on each side of the same chapter.
