My Little Bimbo

Walking along the dirt road that connected her cottage to the rest of Ponyville. Though it just narrowly bordered the Everfree Forests, she never felt too nervous about it. So long as she never ventured more than a few hundred feet or so, even the boldest Timberwolf left her alone. As she walked, Fluttershy’s now big breasts bounced. Though she was already endowed as is, the way they moved now seemed almost impossibly so. Normally, Fluttershy would be extremely self conscious about if anypony could see her tits bouncing like this, hence why she often chose to walk slowly.

But today, Fluttershy’s worry over being late to meeting up with her friend, more than made up for any previous insecurities. Though as she made her way along the dirt roads, she never once thought about what would happen if anyone saw her like this. The way she moved only seemed to make her panting harder and harder, both her boobs and ass were bouncing in a way that could cause any stallion who would be fortunate enough to see her, to burst out in a hard boner.

Her nipples were soft, but were getting bigger as it rubbed against the soft fabric of her shirt, and while that seemed to send a tingling figure through her body, Fluttershy didn’t seem to even notice. As well as this, her hips swayed from side to side almost hypnotically as she walked. If she was in town walking like this, there was no doubt that many stallions, and even some mares would turn their heads to gawk at her lustfully. But Fluttershy was oblivious to any and all of this. Eventually, the town of Ponyville came into view, but just as she was getting to the town, she saw a decently sized lone cloud.

“Rainbow Dash? Are you up there?” Fluttershy called out, standing a little under the cloud. She recognized it as her friend’s napping cloud, so wanted to be sure. “I’m sorry I’m so late, but I wanna show you something!”

“Huh…wah?” Rainbow groaned, lifting herself up from her cloud. Rubbing the sleepy from her eyes, she looked down to see Fluttershy waving at her. “Oh? Fluttershy? Hey!” Spreading her wings, the athletic pegasus descended to a few feet in front of her friend. “What took you so long? I was so bored waiting, I ended up taking a nap!”

“I know, I know, I’m sorry. But I want to show you something.” Fluttershy commented, gesturing her hand towards the amulet. “Isn’t it lovely? I got it in a package today.”

“Oh, well, it’s shiny, but not really my style.” Rainbow commented, looking at the red gemstone. It was bright in the sunlight, and though not fully interested, she couldn’t look away. “So who sent it?”

“Um…well…I don’t know…” Fluttershy blushed as she explained. “But it was addressed to me, and it does look lovely.”

As the two of them spoke on and on, Fluttershy couldn’t help but look at Rainbow. She’s looked at her friend before, there was something a little different about this time. The petite blue pegasus typically wore work out shorts, and a short shirt that just barely covered a sports bra. The mare was athletic, always working out in order to train and would fly with the Wonderbolts. But because of this, her chest was small, almost flat, and her hips weren’t too wide as she was on a strict diet.

Compared to Fluttershy, Rainbow Dash was her borderline antethisis. A bit shorter, barely a chest or ass, extroverted and extremely social. There were numerous times the timid pegasus envied her athletic friend. But then again, Fluttershy couldn’t even begin to imagine what it would be like to be that overly social with others. She would often bring Angel with her just to go to the marketplace, and yet she was aware that Rainbow wasn’t just friendly and loved to socialize, but has had far more ponies in her bed than Fluttershy.

“So, wanna hear what happened to me the other day?” Rainbow asked, looking at her friend. “Trust me, you’re gonna laugh.”

“Sure, I’d love to.” Fluttershy replied, knowing Rainbow’s style of humor was a little more explisit than she could handle, but couldn’t say now. “Just…don’t give me too many details.” Rainbow giggled as she began.

“So there I was, flying as fast as I could.” Rainbow said, starting her story, all while Fluttershy looked at her friend. “And when Soarin suddenly…” There was just something about her as she spoke. “...help him…” Something the timid mare just couldn’t place her finger on. “...his fat cock…” Her words seemed to become little more than mumbles. “...slapped me right in the face…” And each inch of her body kept Fluttershy’s eyes all over her. “...I sucked his dick…” She just couldn’t look away. “...and then I…”

Fluttershy couldn’t help but stare more and more along Rainbow’s body, from her small tits, down her fit belly, and modest flank. But what’s more, her mind was starting to wander as fantasies never conceived in her mind were manifesting. The blue pegasus’ chest seemed to swell out, becoming even bigger than Fluttershy’s, and her hips grew almost just as big as hers were. But just as soon as thought this, she shook her head, confused over why she was thinking this; even closing her eyes for a moment.

‘No, no, no, this is bad.’ Fluttershy thought to herself, her mind racing as more and more images of an incredibly busty, and super slutty Rainbow shifted around. ‘I shouldn't be thinking of my friends like that.’

“Fluttershy? Hey Fluttershy!” Rainbow commented, her tone sounding a little different than before. As soon as Fluttershy opened her eyes, she saw that her friend now looked exactly as she had just thought of. “Like don’t close your eyes on me, that's super rude!”

“I…I…I…” Fluttershy stuttered nervously, her eyes unsure what to look at first. “R-R-Rainbow…Dash?”

Rainbow was the same, sort of. Her tits were now a few sizes larger than Fluttershy’s, with hips to rival hers as well. Her clothes seemed to have changed a little too. Her jogging shorts were tight against her flank, leaving it to be more like that of a large pair of panties or a thong, while her sports bras seemed to someone stretch to hold back the mare’s tits, and her shirt was so short, Fluttershy could see the underboob whenever Rainbow took a breath. These tits were so massive, they were even putting her own impressive size to shame.

“Hey! Are you staring at something?” Rainbow asked, her tone sounded almost like flirting as she looked at her friend. “Or do you see something you like?”

“I…uh…you see…it’s just…” Fluttershy nervously responded, not fully sure what she could do. Shaking her head, she blushed as Rainbow was starting to get a little too close to her. So much so, both their tits were pressing together. “R-Rainbow, I think you’re a little…” She cooed a little, feeling a shiver of pleasure as she saw the mischievous look on her friend’s face. “...a little…t-t-too close…”

“I think I’m fine, and speaking of fine.” Rainbow commented, reaching out to grope at Fluttershy’s breast. “Girl! Were your tits always this soft? And no bra? Feeling a little naughty today?” Fluttershy only shivered as her friend was making her nipple tingle and get harder under her shirt. “Fuck…Fluttershy, these things are huge, like what are you feeding them? Not that I mind, I mean tits this good shouldn’t be kept to yourself.”

Pushing forward, Rainbow had pinned Fluttershy with her massive breasts. Both mares were so close and the timid mare could feel a shiver running through her spine as she was feeling a small tingle within her body. Shaking it off, she shifted a little, but all it did was cause her own tits to push against Rainbow’s. This caused the sportsmare to look at her friend with lustful eyes. It was strange, uneasy, and yet there was something about soft these huge breasts that seemed to send a shiver through Fluttershy’s spine.

Though Fluttershy didn’t notice it, she too had changed. Though her tits and ass seemed to swell a little more, her clothing had changed. Rather than the same sweater and short shorts, she was now wearing a brighter red tub top that hugged around her tits to keep them perky and forward, while her hips and ass were just barely covered by a short, black skirt. The term “slutwear” would normally come to mind if Fluttershy could see herself, and yet she didn’t even notice her clothing had changed.

“R-R-Rainbow?!” Fluttershy gasped as she tried to back away. “What are you doing?”

“Just admiring your rocking tits!” Rainbow chuckled, smirking at her sheepish friend. “I mean, look at mine!” She laid her hands along her gigantic rack. “Yeah, pretty impressive right? Shit, I bet I got the biggest pair in Ponyville, fuck…Equestria even!” She then looked at Fluttershy with a smug expression. “I got the biggest tits, and I’m still the fastest flyer around. Oh yeah, I’m just that awesome!”

Fluttershy continued to stare at her childhood friend. Rainbow Dash had always been very boastful, it was part of her nature after all. But she was certain this blue pegasus never had breasts like that, as well as this, she was also very certain that Rainbow wasn’t into mares like that, especially her. Sure, the athletic mare liked to party here and there, and drink more hard cider than she should, but she’s never portrayed herself in such a manner.

Fluttershy was nervous, unsure as to what to do. Swallowing hard, she saw that Rainbow had a predatory look in her eyes. It was something Rarity had warned her about before, but that was for vulgar stallions who would take advantage of her good nature and blessed endowments. Never did Fluttershy ever think for a moment that these nervous feelings could be triggered by Rainbow Dash of all ponies. Swallowing the last of her courage, she tried to speak, but her voice trembled.

“Uhh…uhh…I-I-I’m sorry, Rainbow…” Fluttershy stuttered, backing away and started to walk more towards the town. “But I gotta go…okay, nice seeing you…bye!” Before Rainbow could respond, she was already moving ahead.

“Oh…okay…I’ll see you later!” Rainbow called out, waving at her friend as she let her leave. Once Fluttershy was far enough away, she sighed. “Shit…was it something I said? Maybe I was laying it a little too hard on her.”

Taking flight, Rainbow relaxed back on her cloud. Laying back, she let her huge tits rest on her body. She was so soft, and she felt as if she had a burning sensation throughout her entire body. Swallowing hard, she started to grope and tease herself. As she did, Rainbow closed her eyes, fantasizing of herself and Fluttershy in this cloud. How she wanted to feel her childhood friend’s own soft body against her own. It was an immense pleasure that was making the blue pegasus moan out.

“Fuck…that feels so good!” Rainbow moaned, twitching as nearly her entire hand was fingering her sobbing wet pussy. “Fluttershy…fuck…I’m sorry, but you’re so sexy…” Groaning, she felt as if she was about to cum. Her orgasm was small but very wet, soaking the cloud she rested on so much that it was causing a small amount of rainfall from it.

Fluttershy, not stopping for a moment, couldn’t help but think about what she had just witnessed. Sure, Rainbow was that outspoken to some ponies. She had seen her friend’s “relationship” with Soarin, as well as other members of the Wonderbolts, but to straight up hit on her like that…to push those large, beautiful, massive…Fluttershy shook her head, trying not to think about it. There had to be some explanation for it. Anything, so long as it made sense.

“Rarity! Yes, Rarity might know something.” Fluttershy said aloud to herself. “I just gotta ask Rarity!”
