Rainbow Dash was feeling quite bored and needed some excitement in her life. Scootaloo was busy being with the CMC, so Dash decided to check up on her friends. Twilight was the first, but Spike refused Rainbow from coming in saying Twilight was in the basement doing experiments again. Dash checked on Applejack, but remembered she was at another rodeo. Dash skipped Rarity seeing a long line forming outside her shop. Next she visited Pinkie Pie, but Sugarcube Corner was being remodeled and Pinkie needed to watch. Lastly, Rainbow Dash finally decided to check on Fluttershy. Fluttershy shouldn’t be busy she figured.
Finally arriving at Fluttershy's cottage, Rainbow Dash finally noticed how long she had been running for, not having a break in-between her friend’s home. Hopefully Fluttershy had some kind of refreshments somewhere around the house, Shy wouldn't mind. They were friends back since Flight school after all. Rainbow Dash began to knock on the door and no answer came.
"Fluttershy you in there?" Dash knocked again and again no answer. She decided to open the door, and not being a surprise the door was open and not being a surprise the door was open. The door being open in case a furry animal found its way to her cottage. Dash entered and saw nothing wrong. She started to look around and spotted a glass of water. "I'm sure Fluttershy won't mind if I take this from her." She said mostly to herself since no one was around. She grabbed the glass and chugged it down. It had a bitter taste to it, and rather tangy aftertaste. "Some weird water she has."
After finishing the glass, Dash can hear the door open, as the pink haired resident entered her home holding bags in each hand, seems like she just finished shopping. "Hey Shy, need help?" Dash started to walk over, but never realized she started her friend.
"Oh my, Rainbow Dash what are you doing here?" Fluttershy said nearly dropping her bags.
"I was feeling bored and wanted to hang out with anyone. I hope I wasn't interrupting anything." Rainbow Dash looked around hoping it was fine for her to stay.
"Oh no, its fine, I was about to start feeding the animals." Fluttershy set the bags down and began to look around the kitchen as if something had gone missing. "Dashie have you seen a glass here? It was meant for Mrs. Bigglesworth."
"Umm yea I actually did see one and drank it, thinking it was water." Dash felt bad now drinking something that was important.
"Oh my, that glass was meant for Mrs. Bigglesworth so she can feed her litter, and I don't know what it'll do to a human. Zecora said there were no records of a human drinking it." Fluttershy stared wide eyed at Dash waiting for results.
The two stood there waiting for something to happen, but time passed by as nothing happened. "Nothing’s happening Shy. I guess you gotta have boobs for it to have effect, and last I check, I'm as flat as plywood" Rainbow Dash was confident.
"Alright Dashie, well since you're here, would you like to stay and watch?" Fluttershy started to go through her bags pulling out various animal feeds and such.
“Uhh, yea sure I suppose I can do that. Maybe I can help out a bit too right?” Rainbow went over to one of the bags and began to pull out various things she had no idea about. “Actually I have no idea what goes to who. I’ll just follow and watch.”
Fluttershy laughed a bit at Dash’s honesty. “It’s okay Dash, I’ll manage by myself. No need to worry, if something goes wrong I’ll ask. How is Tank by the way?” Fluttershy went over to the bag Dash was looking through and grabbed what she needed and moved them elsewhere. She placed everything in a different group. Fruit group, meant group, veggie group, and etc.
“Tank is doing great, the idea helps out a lot for him to keep up with me, but I don’t use it very often for him actually.” Which was quite true, Rainbow did like the idea of Tank being able to catch up to her but using it too often got annoying rather quickly. “How’s Angel doing? Still being annoying?”
Fluttershy gasps. “Rainbow Dash how rude of you to call him annoying, when he isn’t. He is still a child and has much to learn.” Fluttershy moved over to the bird houses and began to pour bird feed into the bird feeder.
“I suppose you’re right, sorry Shy, I never thought of it like that. Guess I’m use to the old turtle I got.” Fluttershy corrected her as she usually does. “Tortoise yea, does it really matter?”
“Well no it doesn’t but since I’m an animal expert it quite bothers me, sorry.” Fluttershy continued to move around the house feeding those first inside then she will worry about the ones outside. From time to time Fluttershy and Rainbow Dash would strike up a conversation or two about different things, of course Rainbow brought up Wonderbolts, while Fluttershy listened. Eventually the two head outside to a clear sky.
Fluttershy moved about the area around her cottage, Rainbow Dash followed behind doing her part every now and then. She didn’t do much, not wanting to mess up even more then she already had from earlier. She always had an easy time messing up stuff, but usually fixed the problem by the end of the day.
Rainbow Dash never knew how many critters and wildlife animals Fluterrshy had to care for. She always figured it was the ones inside and their friends, but was she wrong. She had seen so many animals she didn’t know the names for. The only things outside she recognized was a bear, ferrets, and rabbits, the rest were quite new to her. Nevertheless it was a learning experience for her, and was quite enjoyable to be honest. She never thought caring for animals would be fun. Well there was Tank, but he was a pet, a companion so it was different.
“How can you manage to afford so much Fluttershy? You don’t really have a job last I checked.” It was quite a mystery how Fluttershy can get so much feed for the animals.
“Oh well I help the vets from time to time, and they pay me, I always decline but they know I need the money in order to feed the critters.” Fluttershy said as she finished up the last of the feed for the animals. “There now little animals, eat up if you want to grow up, they’ll be more of that tomorrow.” Fluttershy mothered them as if she was the mom. It was starting to get dark and was best to head inside.
Rainbow Dash and Fluttershy began to walk inside, making some more small talk. Mostly of how Fluttershy is able to keep track of all the animals. Fluttershy giggled and reminded Rainbow it’s the same way she remembers the Wonderbolts. Dash felt a little embarrassed having memorize that much.
Once inside Fluttershy offered her friend if she wanted dinner. Rainbow of course agreed, she was starving having not eaten anything all day. Fluttershy set about to start cooking, till she heard kittens crying off in the corner of her house. “Oh my Mrs. Bigglesworth I forgot, your kittens need to be feed.” Fluttershy began to search her fridge to see if there was anything she can give to the poor kittens.
Meanwhile, Rainbow Dash was feeling a tingle in her chest. “Umm Shy, my chest feels funny for some reason.” She couldn’t help but feel heat build up in her chest
“Oh my, don’t tell me you’re having a problem also. I can’t treat others as well as I do with animals.” Fluttershy was worried for her friend.
Soon the tingling went away. “Ahh much better, it away Flu-” Just then the heat came back, and Dash looked down to her chest to see two mounds sticking out. “Umm Fluttershy, what did that drink do again?”
“It’s supposed to help nurturing animal’s mother produce milk for their young ones, why?” Fluttershy looked at Rainbow Dash with wide eyes. And soon enough, the two small mounds on Dash’s chest began to expand outward, stretching forward. The shirt slowly rising, as it began to wrap around Dash’s newly formed breasts; going from a nonexistent A-cup to a moderate B-cup in thirty seconds.
“Heheh, would you look at that? That drink made my boobs grow, now I ain’t so small chested, huh?” At first it felt weird, since Dash never had to worry about the added weight breasts would bring. The weight was nothing really, but it was different from having none. She quickly adjusted to the weight in no time. Nothing was going to ground her for so long. “Look Fluttershy, that drink actually has some effect on human it seems.”
“Oh my you’re right, we should tell Zecora about this, something worse could happen.” As she spoke, she couldn’t help but notice Dash’s nipples being rock hard poking through her shirt. “Umm Rainbow, are you wearing a bra?”
Rainbow ignored the question far to being playing with her boobs. “Umm actually no, I never bothered to buy any cause I had nothing to hide. But I guess now I’m gonna have to get some huh?”
“It’s okay Dashie, you can borrow some of mine, since I had to go through quite a few actually.” Fluttershy blushes having remembered all the bras she bought when younger that no longer fit her D cup breasts. “Let me go grab them for you.” With that Fluttershy began to walk upstairs to grab. She couldn’t stop thinking how the drink made Dash grow so fast, though it was a small change, but it takes years for a girl to grow to any size. From downstairs Fluttershy can hear the kittens crying out again. “Oh my, I forgot about them.”
Also from downstairs a voice is heard. “Umm Shy, we got bigger problems I think.” Soon enough a ripping noise is heard. “Oh no no no no no. Stop doing that.” Fluttershy couldn’t tell what was going on, and soon raced downstairs to see that Rainbow’s breasts had grown again, and enough to start ripping some of the shirt it seems. “Man, this sucks, I actually liked this shirt.”
“What happened?”
“I have no idea, I was just standing here waiting for you, until the cats started to cry again and soon enough my chest is swelling up again. It’s crazy I tell you.” Judging from their size Dash had to guess that she was now a D cup, in only a matter of minutes. She knew it wasn’t normal, since she had seen Fluttershy take forever to get to her current size, while Dash was breaking the laws of the physics as if she was Pinkie. As she began to touch them, she started to notice how sensitive they were to her touch. Letting out a moan here and there.
Fluttershy let out a gasp seeing Rainbow Dash caress her chest. “Rainbow, stop that right now, you can’t do that in public.”
“It’s a good thing I’m not in public then huh? Instead I’m with my best friend who will help me.” Rainbow stepped closer to Fluttershy with a sultry look to her eyes. “It’s not like we’re strangers to each other Shy, I’m sure you’ve thought of doing it with another girl haven’t you?”
Fluttershy began to blush. “Umm well yes that is true, but now isn’t the time I think.” Rainbow Dash took this time to lean in. “Dash what are y-” Rainbow Dash started to kiss Fluttershy, pressing herself against Fluttershy. Fluttershy gave in rather quickly, as she started to remove her shirt and bra as best as she can with Rainbow Dash assaulting her mouth, tongues moving in between the two. After a struggle and Rainbow pulling away, Fluttershy was able to remove her top, revealing her mounds; the two women had to be about the same size.
It was then the two got together again to resume their kissing, their chest mushing with the other, tit on it. It was so much for Rainbow Dash, her boobs seem to be really sensitive, or maybe she just needed to get use to the feelings, Fluttershy didn’t seem to have a problem at all with their flesh touching. Which was true, Fluttershy having had breasts for such a long time had grown use to the sensitivity that they came with, though she never did anything sexual often, she had experienced what kind of pleasure they brought to one.
For Dash it was still a new experience, and she needed a way for it to calm down, proving to be a task at first, but now that Fluttershy was helping her, it was starting to slow down. Or at least she thought it was, still the kittens started to cry again. Fluttershy this time broke off the kiss.
“Oh my, the kittens, I need to do something.” They resumed their kissing and broke again. “The little ones must be so hungry.”
“You can’t leave me like this Shy, I still need attention.” Which was true, the sensitivity was coming back again, and stronger too it felt. Shy looked worried, she had two things to worry about, her friend who needed some special attention, and her kittens that needed food. “So what will it be?” Shy stayed quiet for a moment thinking of what to do.
Fluttershy knew what she needed to do. She stood up and looked at Dash, with a look of lust, her friend needed her, and she needed Rainbow Dash at that moment also. She tackled Dash down, and began to lick at Rainbow’s nipples, and sucking on them. Rainbow Dash didn’t complain about the choice Shy made as she made noises of approval, moaning and telling Shy to keep going and asked for more.
As Fluttershy kept sucking on the nipple, she began to feel herself lift up slowly. She looked down and noticed that Rainbow’s chest was still enlarging further. As they swelled Rainbow could feel them touch more of Fluttershy, further arousing her, making her cry for more, hoping it wouldn’t end. But soon enough they did. They now seemed to be a G cup, already passed Fluttershy, who is believed to be the largest in Humanville. In less than an hour, she had gone to flat chested to G cup, she was pretty sure that was a (academy) record.
“Oh my goodness, Rainbow, your chest is huge, I didn’t think it was possible. We need to get you help.”
“No Shy don’t. Just finish me I’m so close, I really need it.” Shy had a feeling Rainbow was close, as she was too, for some reason, just feeling those orbs was enough to turn her on, which was new to her. She had never heard of anything like that, it’s usually stimulation that would cause an effect, and she was stimulating Rainbow, not the other way.
No matter, all Fluttershy wanted to do now was to make Rainbow Dash (and herself) happy with this little fun they have. She began to place her hands on both breasts and move them in a circular motion, making Rainbow yet again to moan out in pleasure. This drove Fluttershy on further to continue, with each circle completed, the closer the two were. She decided to take a nipple into her mouth again as she began to suck what she can, though nothing was being given, she just realized this, but nevertheless it felt good.
“Keep going, I’m about to cum.” And then as the words left, Dash’s body shook from the orgasmic feeling, she breasts seemed to have swelled up larger and then quickly started to shrink back down into her chest.
Fluttershy having herself reach orgasm as well, began to notice her head sinking back down onto Rainbow’s body. “Dash, what happened, you’re flat chested again?”
Rainbow having not yet recovered lied down panting at having such a good time, till she decided to look at what Fluttershy had just said, and soon enough noticed she was flat again. “Oh man, what happened? I was having so much fun and now they’re gone.” She pouted at having such a bountiful chest be gone.
“Oh, don’t worry Dashie, maybe it just wasn’t meant for you. I’m pretty sure your body wouldn’t be able to handle it properly since you’re always on the move.” Fluttershy tried to look at the positive side hoping to cheer her friend up.
“Yeah, I guess you’re right Shy, I don’t need a big chest, and besides it would keep me grounded to do anything, but it just felt so good.” Rainbow clearly wished it would happened again, she quite longed for the feeling now.
After a while the two sat in quiet, until a cat is heard purring. The two decided to check on the cat to see what was happening to see that Mrs. Bigglesworth was feeding her children properly. “Oh, Mrs. Bigglesworth you’re finally feeding the kittens, I’m so proud of you. Well, seems like everything is fine now, Rainbow, you can leave now if you want.”
“Yeah, after a day like today, I think I’m gonna head back to my place, thanks again for the time we spent Shy, I don’t think today could have gone better.” The two hugged each other goodbye, thankfully it was the dead of night and no one should be able to notice Rainbow walking around naked as she walked back to her house.
