"Dashie?" a sweet voice called, bringing Rainbow Dash out of her dreamy state. Though she was still dazed, her first thought was to look at her alarm clock.
"It's 2:35," she complained to whoever had interrupted her sleep.
"I'm sorry," the voice said quietly, "but I need to ask you something."
"Wassup?" she mumbled.
"Can I sleep with you tonight?"
"Can you-"
Now fully alert, Rainbow Dash looked up from her pillow towards her doorway, where a darkened figure stood before the light from the hallway. She could make out the curls of hair, chubby cheeks, and voluptuous curves of her new roommate, Pinkie Pie.
"W-why do you want to sleep with me?" Rainbow asked, blushing madly.
She could see her friend lower her head in response. "I had a bad dream."
Rainbow released the breath she was holding in. Of course she's only talking about sleeping and not...anything else."
Had it been anyone other than Pinkie, Rainbow would have asked if they were five years old, laughed at them, yelled at them for waking her up, and told them to go back to bed.
"Pleeeeeeease?"
But, unfortunately for Rainbow Dash, the one girl she couldn't possibly say no to was the one who was standing at her room's doorway.
"Fine."
She saw Pinkie's head perk up before she darted over to the bed. Rainbow, surprised by her friend's speed, barely had enough time to roll out of the way as the force of nature lept onto the bed next to her, taking the warm middle spot where Rainbow had just been sleeping. As Pinkie snuggled into her bed, Rainbow Dash felt the covers being dragged off her carefully more and more. When the blanket was completely removed from her body, she looked down at herself and realized that she had chosen only to wear a T-shirt and a pair of boyshorts to bed, with nothing else to keep her warm. She felt herself start to shiver and get cold as she now only had her arms and hands to warm herself with.
She looked over to her friend, who had taken her covers and wrapped herself up like a caterpillar in her cocoon. Rainbow thought Pinkie looked cute like that, but she also knew that if she didn't get some kind of covering, she might freeze to death.
"Pinkie," she whispered.
"Hm? What is it, Dashie?"
"Can I have some of that blanket? I'm getting kind of cold."
Even though it was mostly dark in her room, she could see Pinkie Pie's eyes open wide. "Oh, I'm sorry! Hold on." She wiggled around for a few seconds before the make-shaft wrap became undone and opened up to Rainbow. "Come on in!" Pinkie smiled.
Rainbow blushed as she saw Pinkie Pie clearly for the first time now that she was almost fully awake. She had chosen to wear nothing but a pink bra and matching panties to bed. Even though Rainbow thought she had an amazing butt, her attention was more focused above her waist and just below her chin. The bra fit almost too snuggly around her large boobs, and it showed off her cleavage very obviously. She blushed and turned away when she realized she had been checking her friend out for a little longer than necessary.
"I-I meant, like, you give me some of your covers."
"But it will be a lot warmer for both of us if we snuggled close together."
The thought of being so close to the almost naked girl gave Rainbow a feeling of ecstasy. Rainbow Dash would never admit it to anyone, but she couldn't help but feel attracted to Pinkie Pie. Maybe it was just because she liked girls and Pinkie was, in fact, a girl. Maybe it was because of the big smile that she constantly had on her face. Maybe it was because she had one of the sweetest personalities of anyone Rainbow knew. Maybe it was because she shared in a lot of Rainbow Dash's hobbies, especially fun and parties.
Or maybe it was because of her massive stripper titties.
Either way, she couldn't will herself to say no to her, maybe out of friendship, loyalty, or something else.
"Okay," Rainbow said, nervously. She then scooted her body over near her roommate and onto the blanket. As soon as she was close enough, Pinkie dropped the blanket and tucked it under Rainbow's body so that they were now both in the cocoon. Rainbow felt herself heat up almost immediately
"There," Pinkie sighed, "now we're both snug as two bugs in a rug."
Rainbow Dash tried to turn away from Pinkie Pie so that it wasn't so awkward facing each other, but the blanket was too tightly wrapped around both of them.
"What's wrong, Dashie?" Pinkie asked when she saw Rainbow struggling to move.
"Nothing," she said, avoiding eye contact.
"You know, if you're still too cold, you can come closer to me. I'm nice and toasty!"
"Um, no thank you Pinkie."
"Awww, don't be shy! I'll come over to you then!"
Before Rainbow had a chance to react, Pinkie wrapped her arms around her back and pulled her in close. Now Rainbow found herself being smooshed into her friend's body in a big bear hug. Rainbow couldn't help but blush as she felt Pinkie's breasts push up against her far less impressive ones.
"Wow, you really are cold," Pinkie said, although Rainbow felt lots of heat now. "It's a good thing that I'm so warm."
"Yeah, your really hot," Rainbow mumbled before she could catch herself. All Pinkie did was giggle in response.
What amazed Rainbow Dash more than anything and made Pinkie Pie more desirable to her was that she seemed completely oblivious to how sexy she was. As Applejack was happy to point out, Rainbow Dash was a horrible liar, and anytime she would let something slip that Pinkie might have picked up on, she casually threw out some lighthearted response and never came back to it. It made for some pretty interesting conversations between the two of them.
Pinkie seemed to do everything to make her roommate want her but did not have any intentions whatsoever. Pinkie was a few inches taller than Dash, so every time she would hug her, the athlete's face would go straight into her giant rack. It wasn't like Rainbow was complaining, but every time they broke apart, she couldn't help but want more. She wanted to touch her boobs, play with them, taste them.
Suddenly, just when she was about to drift off into sleep, she felt her top half being pulled closer to Pinkie. When she opened her eyes, she found that her face was about an inch away from her massive rack. Rainbow felt her face burn again as she stared at her friend's most tempting area.
"Um, Pinkie?" Rainbow asked.
"Hm?" Pinkie replied, almost asleep.
For a second Rainbow considered telling her to stop, and telling her to let go so that they weren't so close. But the thought of being in such a hot cuddling position for the whole night was enough for Rainbow to shrug off any anxieties.
"Never mind," she told her, to which Pinkie only hummed in reply.
Then she was pulled even closer, and everything went black as all of the light around her was obscured by Pinkie's breasts. They moved to make room for her inside of her impressive cleavage. Her mind went wild with the thoughts about how she was now essentially motorboating her boobs.
She wondered if she should wake her friend up, or if she was even asleep at all, or maybe she was doing it on purpose. She didn't want Pinkie to wake up and think that Rainbow was a pervert and had purposefully put her face in her tits on purpose. Then, not only would she be losing her crush, but her best friend as well.
Then again it wasn't like Rainbow Dash was uncomfortable. She could still breathe, it was dark so she could probably sleep easier than before, Pinkie's arms around the back of her head were firm but not crushing her, and she had two soft pillows that were far more comfortable than the ones that she slept on every night. They felt like memory foam, which was surprising to Rainbow considering how heavy they must be to Pinkie Pie.
Thinking about that made the urge to touch her hands even stronger now, and the only thing holding Rainbow back was the friendship that the two had built up over the years. But Pinkie Pie was making it very hard to think about that right now.
Although Rainbow had touched breasts many times in her life, her own to be exact, she had always felt envious of the women who had bigger ones than her. Even though she knew it would have been harder to compete in sports with them, she could have had the energy to power through. It eventually got to the point where she realized that she wasn't just jealous of big tits, but she was also attracted to them, and being around Pinkie so much gave her the opportunity to realize that. Nevertheless, she never tried to pull anything with Pinkie, even though she always made herself so tempting.
But as she heard Pinkie Pie start to snore softly, the temptation became too much for her to bare. She had to touch the boobs.
Slowly, she brought one of the hands that had been on the mattress and went to touch Pinkie's breast right above where it covered her ear. It felt almost like an electric shock of excitement hit the rest of her body when her fingertips made contact with the top of her breast. The soft, warm skin felt like magic in her hand, tempting Rainbow to sink her hand even further into the soft marshmallow skin. She was scared that her roommate would wake up and see her, so she paused there for a minute and listened. But all Rainbow could hear was Pinkie's deep breathing, so she decided to keep going.
She then pushed a bit of pressure into the tit, trying to get a better idea of what they really felt like. To her surprise, they didn't feel hard or heavy, but soft and light. Rainbow wondered how something like this could defy physics so much. She felt that she needed to research more.
She put the rest of her fingers around the breast and put the palm of her hand to the middle of her skimpy bra. She cupped the breast in her hand and squeezed it slightly. The soft flesh seemed to move with her hand. She gave it another squeeze and this time she heard Pinkie's breath hitch. She stopped, suddenly very afraid, but when the breath came out as a sigh, she continued. She molded the mound like it was dough in her hands and tried to be as gentle as possible, but it was becoming almost impossible for Rainbow to control herself.
By this point, she could feel herself starting to get very turned on, and she knew she had to stop otherwise she would have to get up from her heavenly position and go to the bathroom. Plus, Pinkie Pie could wake up at any time, and even though she had fun, she still did not want to ruin their whole friendship over her sexual adventure.
Rainbow decided that her curiosity had been fulfilled, for now at least, and took her hand off Pinkie's big tit and snuggled into her cleavage to try and sleep. As she drifted off, she couldn't help but imagine a nude Pinkie Pie surrounded by candy and coated in whipped cream and sugar. Her whole thing with Pinkie was something Rainbow knew she had to shake, but they were her thoughts.
Plus, it was Pinkie Pie, and she naturally smelled like candy and sugar.
When Rainbow woke up, she was surprised to find not only her face free of its soft prison, but that she was alone in the bed. She was wrapped up like a burrito in her blankets, still snug and warm. After taking a few minutes to wake herself up, she struggled out of the tightly wrapped covers and got out of her bed. She didn't bother changing out of her sleepwear since she wasn't planning on going anywhere.
She walked into the hallway and toward the little kitchen and dining room area in their apartment. Pinkie Pie was standing at the oven with a spatula in her hand, still wearing nothing but a bra and panties. When she saw Pinkie's exposed rear, she found herself tripping on a soccer ball that she had left out. She quickly grabbed onto the wall to stabilize herself and not fall on her face, but in doing so she caught Pinkie Pie's attention.
"Morning, Dashie!" Pinkie smiled when she saw Rainbow in the same room.
Rainbow quickly adjusted herself to lean up against the wall to look cool. "Hey, Pinks."
"I made you breakfast!" Pinkie exclaimed as she pointed to the stack of pancakes on the table, surrounded by chocolate syrup, whipped cream, sprinkles, and blueberries. She also set up two plates with silverware and a glass of orange juice.
"Thanks." Rainbow sat down at the table, using a fork to put two pancakes on her plate. She decided to pass on all the sugary toppings to stick to her diet, but she knew they would be gone after breakfast anyway.
"Thank you so much for letting me sleep with you last night!" Pinkie exclaimed. "It was nice to have a buddy to cuddle up with and make all the bad thoughts go away! You really seemed like you were enjoying it too!"
Rainbow almost choked on her pancakes. She took a sip of her juice before asking, "W-why do you say that?"
"After I woke up, I tucked you in like an itty bitty rolly polly and you didn't even wake up."
"Oh," Rainbow said.
"And before, when I did wake up, you were cuddling with my boobies."
Rainbow stopped picking at her food and looked at her roommate, still standing at the stove.
"Sorry Pinkie, I-I must have been really asleep, huh?"
"That's okay, it kind of tickled," she giggled. "And you make a really good teddy bear to hold tight."
"You know, Pinkie," Rainbow started nervously, "if you ever...do have, uh, another nightmare, I wouldn't mind if you...wanted to sleep with me some more."
Pinkie turned her whole body to Rainbow Dash and grinned from ear to ear, but Rainbow couldn't help but feel her eyes being dragged to below her chin. "I'd love to!"
Rainbow grinned and sat back in her chair, thinking about what would happen the next time Pinkie had a nightmare.
"Eight...nine...ten!"
Rainbow Dash finished stretching and got ready to take off on her run. After days of waiting, the rain clouds that had kept her inside had cleared to allow the sun to shine today, and all that remained was a cool blowing breeze that shook the trees and cooled the sun's heat. In other words, it was the perfect day to go outside for a run, and Rainbow would not let it slip by. In preparation, she wore a blue shirt with her old school's logo, a pair of shorts, and her favorite pair of running shoes.
Running had always been a favorite pastime for the athlete. It made Rainbow Dash forget about the world around her and all her problems; it was her release. It reminded her of when she was just a squirt, running laps around all the boys in the neighborhood that dared challenge her. The pride Rainbow got from seeing their defeated glares still hadn't faded. Every time she went for a run, she gave it 120% to make herself the world's fastest and most perfect runner.
Smiling, she cracked her neck to the side and back again and prepared to take off. She almost lost her balance when a voice behind her caught her off guard.
"Rainbow Dash, wait!" When she turned, she saw her pink friend running out of the door toward her. She had tied her long curly pink hair into two buns and was wearing a white crop top that tightly hugged her enormous rack. Traveling down, she saw her friend had chosen to wear a pink pair of shorts that weren't too dissimilar to Rainbow's, although instead of showing sleek muscles, they showed a set of pink thighs and a shapely butt.
"P-Pinkie Pie? What are you...you know I'm just going for a run, right?" Rainbow stuttered out, trying to resist Pinkie's curvy body's gravitational force on her eyes.
"I know, but I wanted to join you!"
"Wha-Why?"
"Because I like spending time with you, silly."
"We...won't exactly be talking. I'll be trying to run as fast as possible, and, um, I'm not sure you can keep up." Rainbow chose her words carefully to sound cool while also trying not to be mean to Pinkie.
"I can still try!" she cheered. "Plus, I think I have been getting a little chunky lately. A workout could be good for me."
Rainbow didn't respond, but she knew she was far from obese. Compared to Rainbow, who was a twig and didn't have much in the front or back to show off, Pinkie was quite a bit bigger. However, Pinkie was bigger in all the right places and had plenty to show off, and Rainbow was always attracted to girls who had more to show off.
"I guess that settles it!" Pinkie decided after getting no response from Rainbow. "Oh, should we act like we're in a race together? That'd be fun!"
Rainbow smirked and crossed her arms. "I don't know," she smirked, "You know you're going to lose, right?"
"We'll see about that, Dashie," Pinkie smiled, walking up to her and getting into a bent-over starting track position. Rainbow saw her crop top slip a bit, and she noted with a blush that the party girl had chosen to wear a contrasting black bra along with it.
"O-okay," she stammered, getting into position as well. Although she didn't go downward dog like Pinkie, she bent her knees and set her arms to propel herself forward. "Ready?"
"Mhm," Pinkie nodded.
"Go!"
Rainbow Dash had decided to run her usual route, about three miles long. It started by going up a steep hill for the first stretch, and from there, it was a quick jaunt to the nearby city park. She would run around the entire perimeter of the park, maybe stopping for a drink at the fountain near the end, and then go back down the hill and back to the apartment.
At first, it was a tough course for Rainbow to handle. Even with her training and slick physique, it was still daunting to go up such a steep hill and then continue. It was one of those hills that cyclists stopped at and chose to walk their bikes up unless they were exceedingly skilled. It went on for about half a mile and had no breaks in between, making it tough for just about anyone to scale without stopping. Although it was tough, it helped Rainbow with incline training and keeping her stamina up. Plus, once she got up, she could focus more on speed since there was no longer any climbing.
It was clear that her roommate was not used to it yet, though.
When they started, Pinkie Pie tried to run fast to keep pace with Rainbow, but as her legs met the hill, they seemed to struggle to propel her up the incline. Not even halfway up, Rainbow stopped to let the girl catch up to her. She was surprised that Pinkie was already panting hard, but she still looked determined not to give up. This time, Rainbow moved at a jogging pace so the party girl could keep up with her, but even at the slower pace, her roommate still fell far behind. It took three stoppages before the two girls were at the top of the hill.
"You alright?" Rainbow asked after Pinkie slowly jogged to her. The pink girl had put her hands on her legs and her head down, trying desperately to catch her breath.
"Yeah...Rainbow...of course...I am..." she gasped.
"Hey, if you want to turn around and go back, it's all downhill back."
"No...I'm alright." She stood straight up and wiped the sweat off her brow. Rainbow turned red and looked away. Something about seeing Pinkie Pie all sweaty was really attractive to her, and it became more so when she turned back around and saw Pinkie hiking up her shirt and her boobs jiggling around inside.
She cleared her throat. "Alright, let's keep going then."
"Okie dokie," Pinkie exclaimed.
They continued across the street and toward the park. The two girls could see that they weren't the only ones who decided to enjoy the perfect day. There were some middle-aged people playing tennis on the courts, a bunch of teenage boys playing an intense game of basketball, and many children running around the playground while their parents watched them.
Rainbow found herself going much slower as she circled the park. It wasn't because she was tired or hurt but because she didn't want Pinkie to fall too far behind. Rainbow checked behind her occasionally to ensure she was still keeping pace, at least somewhat, but it seemed like no matter how much she adjusted, Pinkie would still be falling behind.
Rainbow felt thirsty after running around the big park, and she figured Pinkie would appreciate the opportunity to take a break. By now, the athletic girl had lost track of how many times she had to stop for her friend, and now she was starting to feel embarrassed for her.
She got off the trail and ran toward a pavilion with a drinking fountain under its roof. She bent over and pressed the metal button on the fountain. When the cold water hit her lips, she instantly felt a recharge. It felt like ice was being put in her veins, cooling off the rest of her body and giving her energy to power through the rest of the run.
"Nice job, Dashie," she heard Pinkie's voice behind her.
Suddenly, without warning, she felt something slap against her butt. Shocked, she spit out the water in her mouth and started hacking. After clearing her airways, she turned around.
"P-Pinkie? What...did you just-"
"I thought you'd like it!"
"W-W-What?" Rainbow asked, beat red.
Pinkie nodded. "You and your sports buddies do it all the time, so I thought you'd like it if I did it, too! Since I think you did a super terrific job!"
Rainbow shook her head, trying to clear her thoughts. "Oh, well...I mean...you did...never mind. Uh, Y-You did alright too, Pinks."
Without thinking, Rainbow gave Pinkie a quick slap on her buttcheek in return, who giggled sweetly. It was a lot less hard than Pinkie's gesture, but Rainbow didn't want to hurt her. Plus, now she had officially touched her roommate's soft butt, and she seemed to like it, so that was a positive. Suddenly lost in thoughts, the athlete wondered if Pinkie would like it better if she hit her harder like the pink girl did to her.
It was then that Rainbow realized just how kinky she was.
"Thank you! I liked running with you, even though I was behind you the whole time."
Rainbow couldn't help but wonder if Pinkie had been staring at her butt the whole time.
"Anyway, could you please scootch over so I can have a drink, please?"
Rainbow realized she had been standing in front of the fountain, completely fazed out in her sexual thoughts.
"Whoops, sorry."
As Pinkie stepped past her, she looked the opposite way toward the playground, trying to clear her thoughts. She was watching a trio of boys throwing a football around when she heard a snap right next to her.
"Uh oh," Pinkie she heard Pinkie say.
"What's wrong?"
"I think my bra got unhooked."
Rainbow turned her head to look at Pinkie. The pink girl was still bent over, holding her breasts. Rainbow felt her face heat up instantly.
"O-oh," Rainbow mumbled, unsure of how to respond to the situation.
"Can you please help me?" Pinkie asked sweetly.
"How?"
"Just reach under my shirt and hook the straps together."
Rainbow Dash nervously looked around the area. Even though no one had noticed the situation yet, they were in plain view of the playground, and Rainbow knew that they wouldn't want their children to see a fully grown woman reaching into another one's shirt.
"Fine, but can we go over there?" Rainbow asked, pointing around the brick wall of the pavilion they were standing under. Pinkie nodded and followed her friend, still trying to hold her bra in place. Meanwhile, Rainbow was taking deep breaths to prepare for what she was about to do.
The other side of the wall was still in plain sight, but luckily for them, there was no one to witness what was about to happen. Once both girls were ready, Pinkie turned around and bent her back a little. Rainbow slowly tucked one hand under Pinkie's white crop top and grasped onto her loose bra strap. She then used her other and found her other bra strap quickly, trying not to think about what she was doing. That wasn't easy, with Pinkie wiggling around and giggling.
"Stop! That tickles!"
"Do you want me to help you or not?" Rainbow asked. Even though it came out sharper than she wanted, she wasn't angry at Pinkie but embarrassed that someone would see them.
"S-sorry, Dashie. I'll t-try to be less ticklish."
Rainbow furiously blushed as she thought about how she was essentially helping Pinkie get dressed like a little girl, except she had certain parts that a little girl wouldn't have.
Already knowing that the bra was probably a tight fit for Pinkie, Rainbow carefully stretched the bands so they wouldn't hurt her busty friend. She could still hear Pinkie breathing heavily, trying not to laugh, which made her roll her eyes as she tried to get the bands around her back. She crossed the straps in the back and tried to clasp them together. However, when she got them lined up, she realized they wouldn't hook together. She desperately tried to work quickly to stop the awkward moment but couldn't do it. Rainbow then realized that she could see the problem clearly, and it made her face even hotter than before.
"Everything alrighty?" she heard Pinkie ask.
"Uh, P-Pinks?" she spat. "Y-Y-Your, um...bra broke."
Pinkie's eyes widened. "Oh no! Did it really?"
Rainbow nodded, still unwilling to make eye contact. "Yeah, the hooks are shot. There's no fixing this."
"Well, that's okay," Pinkie smiled, "I've been meaning to go bra shopping anyway."
"Is...that so?"
"Anyway, are you ready to keep going?" she asked innocently.
Rainbow turned her head to meet Pinkie's eyes for the first time in what felt like forever. "How are you going to get back with no bra?"
"Easy," Pinkie said. "Uh, could you please let go?"
Rainbow realized she had forgotten to let go of Pinkie's bra. She had been too busy rubbing the cotton on the elastic between her fingers. She let go of the underwear and left the two bands hanging outside Pinkie's shirt and down by her butt.
She saw her friend let go of her ample chest, reach under her shirt, and pull her bra out from under it. Rainbow marveled at how big the cups were when compared to hers. While her bras looked like two pieces of leftover fabric attached to two bands, Pinkie's looked like it was made with a purpose. The soft and round cups stuck out and indicated a much fuller bust that needed plenty of support.
Pinkie then tucked her shirt in to wrap around her boobs to keep them in tightly. Rainbow's eyes immediately fell on the nipples poking through her shirt, now with no bra to cover them. Her friend walked over to a nearby trash and threw the garment away.
"Pinkie, what are you doing?"
She giggled. " I can't wear it anymore, silly, it's broken. Now let's go! I'm all ready!"
"...How are y-you even supposed to r-run like that?" Even though she didn't have massive tits, Rainbow could only imagine how much it would hurt to run without support.
"I just move my legs."
"I..." Rainbow was about to argue but then realized who she was talking to. "Nevermind. Are you ready?"
"Yeppers," Pinkie exclaimed.
"Alright, let's get going," Rainbow said as she began to jog again with her friend behind her. Rainbow tried to clear her head and focus on running, but the temptation of looking back was almost too much for her.
Rainbow's face lit up again when she looked behind her again.
She wasn't sure if it was because Pinkie was still winded from before or because she had a new obstacle to deal with because now she was moving even slower. Rainbow had to keep looking over her shoulder to make sure she wasn't outrunning the other girl. Each time she did, she would see Pinkie's massive rack wobbling back and forth and up and down with each stride she took. Because she was wearing a crop top, Rainbow wasn't sure if she would lose a tit from the top or the bottom because it seemed like either one was certainly possible at this point.
As they ran back home, Rainbow felt paranoid that people were looking at her friend. She could've sworn a car had slowed down to take a peak, and those two men sitting at the restaurant were probably talking about her. She didn't want people to think of her crush like an object because, to her, she was much more than that, more than meets the eye.
But even she found it hard to resist the temptation of Pinkie's headlights.
When they got to the hill, Rainbow decided it was easy for her roommate to go down by herself at her own pace. She didn't want Pinkie to try and stress herself, so she decided that it would be best if she went faster so Pinkie wouldn't bother trying to keep up. Rainbow felt her pace quicken as soon as she started downhill. The cool wind brushed by her face, cooling her off and taking the beads of sweat off her face as she descended further and further down. It was why she liked this part the best. It was a nice little reward after the rigorous run.
Rainbow stopped when she reached the bottom of the hill, just across the street from her apartment building. She put her hands on her head to keep her chest open so she could breathe easier, a trick she had learned from an old soccer coach. After a few seconds of deep breathing, she turned to see how far behind Pinkie was.
Although Pinkie obviously had not managed to keep up, Rainbow could see that Pinkie was jogging at a plodding pace, and she also saw why running without a bra was a bad idea. Pinkie's boobs were bouncing even more inside of her top now that she was going down a hill. When they bounced up, it looked like they were more in than out. When they bounced down, Rainbow thought they would spill out the bottom.
When she finally got to the bottom of the hill next to Rainbow, she bent over and put her hands on her knees, giving Rainbow Dash an amazing view of her cleavage as her boobs hung down. She felt her face heat up even more when she saw far enough down to see the top of her friend's nipples.
She turned away and tried to focus on something else before she got too excited or seemed like a pervert. "You know," she mumbled, "i-if you put your hands on your head, it opens up your tits- I MEAN CHEST...s-so that you'll be able to, um, breathe...easier."
Rainbow cursed herself for the mistake and having breasts on her mind, but Pinkie didn't seem to notice as she put her hands on her head and panted desperately to catch her breath. Now her shirt hugged her chest tight so that her nipples were poking out very clearly again. Rainbow was amazed at how round and perky her tits were, even without a bra. Perky was the only thing she may have been able to brag about her own breasts, but even Pinkie had that going for her. Rainbow felt a familiar ting of jealousy thinking about how perfect Pinkie's boobs really were, but also a longing to be intimate with them.
"T-thanks...Dashie...whew!" Pinkie brushed a bead of sweat off her eyebrow. "Is it hot out here, or is it just me?"
"Oh, it's definitely just you," Rainbow said from the cuff.
The busty girl smiled, "Well, thank you for letting me come with you! Even though I had a little accident, I had lots of fun!"
Rainbow thought about how she almost had a little accident herself, but didn't want to mention it to Pinkie. Instead, she asked the question she had been thinking about since they were at the park. They were both girls, after all, so she thought it wouldn't be weird to ask casually.
"Is it uncomfortable?"
"Hm?"
"Uh, i-is it uncomfortable...running without a bra?"
Pinkie turned her head to the side. "Shouldn't you know?"
Rainbow caught a bit of angst at the last statement. Her boobs may have been small, but she still ran with a sports bra to support herself and reduce injury. "I meant for you. D-did it hurt running today?"
"Not really," Pinkie shrugged, surprising Rainbow with her response. "I mean, it's less comfortable to run with my boobies swinging around, but they don't hurt me that much. I guess I'll just have to wear a stronger bra next time."
"Next time?" Rainbow questioned.
"Of course! I want to do this again with you! You're my best friend, and I want to hang with you as much as possible!"
"Thanks, Pinkie. Your my breast fri- BEST FRIEND, TOO."
"Aww, you're so sweet," Pinkie replied, again missing her friend's slip-up. "And, hey, maybe next time you'll even beat me!"
"Yeah...wait, what do you mean?"
Before Rainbow could react, she saw the pink girl burst at a full sprint toward the front door of their building. Rainbow realized what Pinkie was trying to do and tried to follow, but although Rainbow was clearly faster, Pinkie had just enough of a head start to beat her friend.
"Whoo!" she cheered, jumping up and down. "I can't believe it! I beat the old track team captain at a race! I must be the fastest girl alive!"
Rainbow tried to ignore how her puppies bounced while jumping up, but it got a little hard when Pinkie began approaching her.
"I told you I'd beat ya!" Pinkie beamed, wrapping an arm around Rainbow.
Rainbow's expression morphed into an awkward smile, and she chuckled. "Yep, you sure did."
"Oh my gosh, I need to tell everyone about this! This is so exciting!" The party girl then ran through the building doors, being held open for her by a very confused passerby.
Rainbow Dash just sighed and followed her inside the building, ready to take an extremely cold shower.
