     "I-I have to fit! It's our only way out of here!"     
//-------------------------------------------------------//
"I-I have to fit! It's our only way out of here!"
"Aha! I knew they were here!" Rainbow Dash shouted with a grin and brought up the pieces of cloth. A white tank top that ended right below the chest, and the lower part of a bikini that mostly looked like a small streamer. The cyan mare had been looking for this specific pair for a while now, leaving her friend Twilight to wait on her. Luckily, they were where Rainbow though they would be, in the basement. She took a close look at them, looking for any sign of dirt or tearing, before quickly putting them on her naked body.
The lower part of the suit hugged her large behind tightly as they slid on, threatening to slide inbetween her buttcheeks almost immediately. Rainbow tried to stretch them out a bit further, but gave up after a few attempts, leaving them ase they were. As she picked up the top, she looked over at the doorway and the stairs leading to the underground section of the house, calling out; "Hey Twilight! You can come down now, I found them!"
After a few moments, she heard shuffles coming from the stairs. Slowly, her friend, a slightly larger purple mare, descended from the floor above. She was already dressed in a tight yellow bikini that barely succeeded to cover her frame, and she was blushing slightly when looking at Rainbow. "Well, that's...great." she mumbled.
Rainbow turned around, now with the white top on, and looked at her marginally embarrassed expression, still flashing a cocky grin. "What? Minding me running around without clothes on?"
"Well..." Twilight stroke her arm, "No, of course not, hehe. I was...I was just unprepared to have you be streaking, that's all!" she explained.
Rainbow blew a strand of hair out of her face and chuckled. "Alright then, if you say so." she said and walked by Twilight, taking the opportunity to reach up and rustle her friend's hair. "Come on now, we better hurry if we want to get going to the beach."
"I've been ready, Rainbow." Twilight replied and brushed her hair back with one hand. "You're the one who ran down here looking for your swimsuit."
"Yeah, whatever." was the cyan mare's response. She turned to face the door and noticed it was closed. She grabbed the knob to open it, but as soon as she touched it, the round knob broke clean off the door.
Rainbow froze, the doorknob in one hand, slowly realizing what just had happened.
"What is it?" she heard Twilight ask, before she also noticed the broken handle. "Oh..."
"Uhm..." Rainbow stuttered. She turned to face her friend, who's previously embarrassed expression had turned into one of worry. "Did you close the door?" the cyan mare asked.
Twilight shook her head. "It must've closed by itself when I went down here." she looked at the knob part in Dash's hand and then to the broken part still hanging on the door. "Could I try to..."
"S-sure." Rainbow complied, giving Twilight the doorknob and stepping back. Twilight got down on her knees, her large derriére resting on her heels, and tried to reapply the knob to the doorway, experimenting, twisting and turning it as she went. Rainbow stood silent by with her arms crossed, watching her work.
A few minutes later, the purple mare still had not found any luck in repairing the door. She sighed and rose to her feet, tossing the doorknob to the side in defeat. "This isn't working. I can't repair this." she said and turned to her friend. "We're stranded here."
"What!?" Rainbow gasped. "Bu-but we can't be! How are we going to get out!?" she almost shouted and began to pace around the room.
"Look, I don't..." Twilight started, but halted herself when she noticed what was in one of the walls. A set of small square-shaped windows were sitting right in the wall, about shoulder height, that couldn't be much larger than her head. "...Oh, wait." she finished.
Rainbow noticed the windows as well. Unlike Twilight however, she instantly shone up and headed towards them. "Ah, of course! We'll just go through one of these."
"Uhm, Rainbow...?" Twilight asked and walked up beside her, both of them now standing next to one of the small squares. "Don't they look a bit...small?"
"It's our only bet, Twilight. Do you see another way out of here?" Rainbow told her friend.
She was right, there really was no other way out except those windows. Twilight noted this and turned to examine the window they were standing in front of. It wasn't big at all. Perhaps big enough for a young filly or colt to climb through, but definetely not enough for a fully grown adult. Twilight figured that she would run into trouble right after getting her head and shoulders through, possibly ending up stuck at her breasts. And even if she would manage to fit them through...
My butt... she though to herself and looked back at her stupendous backside. Compared to the window it was enormous, much bigger than Rainbow Dash's and she could even feel the tightness of the bikini when she thought about its size. There was no way they could fit it through that tiny little frame.
She looked back at Rainbow Dash, who was now trying to open the window, and coughed to draw her attention. "Sorry Rainbow. I...I don't think I will the able to fit through that..."
The cyan mare, who had just managed to swing the window outwards, looked at her friend to examine her frame. She then looked over at her own features, feeling up mostly her boobs and butt.
"Yeah, no offense, but you might be a bit bigger than me." she admitted.
"None taken."
"Well, I guess I'll have to be the one going through this thing." she continued and patted the wooden frame forming the tight space.
"Are you..." Twilight began to ask if Rainbow was sure on what she was doing, but hindered herself. She already knew the answer she would get. The house they were in was a holiday house in the middle of the forest. Of course this was the only way, since there was nobody else nearby that could help them out.
"When I'm through, I'll just go around and open the door for you from the other side." Rainbow pointed out and stuck her arms through the window, beginning her clamber to reach the outside.
Twilight simply watched as her light blue friend angled her head past the window's frame, still worried about how things might end up. Rainbow was indeed a bit slimmer than her, her hips were slightly smaller and her ass was a little less round. But her features were still remarkable, she still had wide enough hips and big enough of a butt to give Twilight a reason to worry.
Rainbow, on the other hand, did not think twice about her size and shape, only focusing on what was ahead. Right after her head and arms had barely scraped past the frame, her shoulders reached the frame, and she had to push forward pretty hard on order to fit them through. She wiggled her shoulders, forcing them out piece by piece until both of them were through. When she tried to push herself further however, she immediately felt herself slow down. Her boobs had just reached the window's edge and were now pressing themselves against the bottom of the frame.
The mare tried to jerk her body forward, and bent her elbows downward so she could pull on her tank top. As she tugged on the white piece of cloth, her breasts followed with it. Luckily for her, they were not that small, meaning that she was able to ease them through piece by piece just like her elbows. Although, it made Rainbow worry a bit. If her breasts already made it difficult for her to squeeze through the small hole, what would happen when she eventually reached her even larger rump? Would that ever fit?
Being the kind of mare she was, she shook those thoughts out of her head as she managed to, with a small push, force her boobs out of the window and onto the bright green grass outside. The sun was still high in the big, beautiful sky, with a cool breeze sweeping over her face and rustling her hair gently. This strategy had to work. She was so close.
Maybe my ass will get me into a bit of trouble, but I'll manage eventually! she thought and pushed with her elbows onto the house wall, aiming to fit the rest of torso out through the window as well.
Twilight looked on as Rainbow tried to lift her legs whilst squeezing the rest of her upper body through the tight basement window. Her buttcheeks jiggled slightly with each motion, barely covered by the swimwear. The purple mare blushed and looked away for a moment, not wanting to observe her friend work her behind up and down. Luckily, Rainbow's waist was exceedingly thin, allowing her to slowly lift it into the window with her. But as she did, Twilight got a better comparison view between the cyan mare's rear end and the small square, the former being a little bit larger. She gulped, but said nothing, allowing her friend to remain the struggle.
Finally, Rainbow Dash shoved the last piece of her chest through the small square, resting only on her slim tummy. She was panting softly, but grinned cockily due to her current success in breaching both hers and Twilight's prison. "Heh, easier than I thought!" she said and rested on her arms, pressing her tighs against the inner wall to keep her balance.
After a moment's rest, she planted both of her hands on the grass, straightened her legs and pushed forward. The last piece of her torso went through the window easily. Then, it stopped completely.
Wait, what? Rainbow thought, and pushed forward again. This time, she felt no progress at all. Just a tug from her hips. She looked back and saw her more featured part press itself uneventfully at the frame. Yeah, I knew it was gonna be tough. Guess I'll just... she pondered and pushed forward again. This time she even tried to wiggle her hips in order to make her butt fit further into the passage. It was working...for a short while. Soon, she felt her progress stop again. When she looked back a second time, she saw that only a small piece of her hips and butt had fit through the window.
Aw horseshoes...
Twilight had seen when Rainbow's hips finally had entered the equation, and now saw the effects of it. The cyan mare in the hole was no longer moving forward as her hips were pressing against the walls, and was instead flailing her legs around, obviously trying to squeeze her well-shaped backside through the hole. All her attempts seemed to be in vain however, and she remained still in the same place.
"Curses!" she heard her friend shout. At that point, Twilight finally approached the stuck female, standing next to her butt.
"Um, Rainbow?" she asked. "Do you need my help?"
"N-no. It's fine! I'll just...keep going. I'll be out soon!"
"Rainbow, to be honest, you look a bit stu-"
"I'm not stuck!"
"...from where I'm standing, you certainly looks that way." Twilight remarked and placed her hands on her hips in a commanding tone.
Rainbow Dash didn't answer, but rather kept struggling, wiggling and pushing with all her strength. Slowly, she managed to painfully cram a bit more of her voluptuous behind into the square, now also squeezing her buttcheeks slowly in as well. Like before though, she couldn't progress further than a few inches before stopping fully again. After that, she wasn't able to fit any further through, no matter how hard she pushed, squeezed or twisted. Worst part was she hadn't even reached the widest part of her hips yet, and she was already caught.
Come on! Work it, twist it! she thought to herself as she struggled. Alas, she soon realized it had no effect. Thanks to her large ass, she was tightly stuck in the basement window.
Rainbow sighed and slumped down on the grass, panting from the struggle. She looked back at the window, and found that her hips hadn't even exited the hole yet. The mare groaned in frustration, finally admitting was Twilight had been telling her.
"Alright..." she grunted regretfully.
"Alright, what?" Twilight asked.
"You're right, Twi'... I-I think I might be stuck."
"There's no way to deny that, Dash." was her response. She looked a little bit closer at Rainbow's predicament, seeing how the top of her hips had squeezed into the frame, and figured all that was needed was a bit of pushing from her side. "Listen: you try to go forward, and I'll push you on, alright?"
Rainbow Dash sighed. It was a bit embarrassing, but she knew it would be impossible without her help. "A-alright then." she called back and fruitlessly pushed against the wall again, trying to fit more of her hips into the window. Hearing this, Twilight placed her hands on Rainbow's hips and pushed.
The cyan female could feel her friend's hands press on her backside, and she felt her hips press against the sides of the wall, not actually going any further. Twilight noticed it as well, and slowly put more and more force into the shoving. This caused Rainbow to slide forward a little, before she halted again. Now, the top of Rainbow's bikini part was sticking outside.
"Twilight... ow, stop!" Rainbow finally called out to her friend and slumped down on the ground. The purple mare ceased her pushing and looked at what they had achieved. By the looks of it; not much. "I... I don't think it's working..." the rainbow haired mare continued.
"Yeah, you're right..." Twilight said and noted just how large Rainbow's butt and hips were. The widest part of it had yet to come, worrying Twilight that they she would not be able to fit through. "Listen Rainbow, this might not be the best idea-"
"We don't have any other options, Twilight!" Rainbow called back, trying to wiggle her hips forward with no result. "It's our only way out. We'll just have to keep going... somehow..."
"Well, just pushing won't work." Twilight remarked. She looked closer at her hip area, and suddenly though of the bikini bottom Rainbow was wearing. "Alright then, I guess we'll try some more. Can you see your bottom piece from there?"
Rainbow Dash blinked in confusion and looked back at her wedged rump. Indeed, she could see a small part of her two-piece stick out of the frame.
"Yeah? So what?"
"Try to grab it and pull it towards you." the mare instructed. "That way, you might pull a piece of your wedged skin with you, which will make it easier for your hips to fit."
"Huh, you're right." Rainbow Dash replied. She reached down with a hand to the right hip and fondled with the tiny piece of cloth that was avaible. When she got hold of it, she pulled it forwards and felt a small piece of her hip squeeze further through. She grabbed the left piece and tried to pull that as well, but with one hip already dominating the space, it was much tougher.
"Twilight, can you push me on again?"
The other mare complied, immediately leaning her weight onto the plush butt in the window. Rainbow continued pulling the undergarment, until all of the cloth on that side had slid through the window, yet again exposing blue skin to the frame. She did the same on the other side as well, until both the bikini's side cloths had been pulled through.
Rainbow could feel that it had worked, as the pressure on her hips had increased heavily. However, she also felt that her rear's widest part had just entered the equation, refusing her any further movement forward. She tried going back to pushing, but like before, it had no effect at all. It just seemed like they'd managed to wedge the poor girl even further.
It... hnng... it must be my ass! she thought and ceased the pushing. She looked back and noticed that the front and the back of her swimsuit also were sticking out of the frame. She grabbed the back piece, right at the frame's top, and pulled it towards her.
Twilight was still going strong from the inside, poking and prodding as much of her friend's rear as possible. Suddenly, she noticed how the fabric covering Rainbow's butt slid through the gap, whilst also sliding in between her buttcheeks. Twilight blushed much harder now seeing this, and used one of her hands to adjust her own swimwear.
The cyan mare felt how a part of her slid through the window as she pulled on the clothing, but also how her behind was exposed even further by having the cloth be pulled upwards. Not trying to think on how it must've looked like for Twilight, she resumed her struggle, pushing hard on the wall.
This time they pressed on for an entire minute, but Rainbow Dash still didn't budge. Her hips had been painfully crammed into the small frame, and her buttcheeks squished, refusing to enter the hole whenever any of the mares tried to push her further. Eventually, Twilight called off the struggle from exhaustion. Both she and Rainbow almost collapsed.
"...Rainbow, I...*pant*...I don't think...*pant*...you're going to fit..." Twilight said between gasps. The sweat that had formed on her body made her tiny two-piece stick to her curves.
"I-I have to fit! It's our only way out of here!"
"You're just too big Rainbow. You're not going to fit any..."
"Bu-but...we must!" the cyan mare protested, the feeling of distress creeping into her. She braced herself and shoved hard on the wall without success. She tried pulling at her swimwear again, but could not progress that way either. "Please, Twilight! You have to push me through!"
Twilight saw the stuck mare's buttcheeks bulge against the frame's top, but she was more focused on her friend's hips that refused to move any further into the tight frame. "It's not your...butt that is the problem, Rainbow. It's the hips."
"But I..."
"It's your hips are wedged Rainbow Dash, not your butt!" Twilight exclaimed loudly. She took a determined step forward and stroke her hands at the point where Rainbow's wide hips hit the window sill. She then placed a palm on the mare's rump, the latter only being able to squirm slightly, and gave a light push forward. It felt like her friend was sitting like a rock. "You're not going to fit through. I'm sorry, but that is the truth. You're stuck, really bad."
"What are we going to do then?" Rainbow asked and heaved forward. "This is the only way out, so what can we do?"
"Hmm..." Twilight pondered and took her hand of the blue mare's rear. She looked into the basement, trying to find something that could possibly help them, and suddenly spotted something sitting on top of a washing machine. A full bottle of dish soap. "I got it!"
"What, what is it?" Rainbow asked, trying to twist her hips at the same time.
Twilight went over and snatched the bottle, returning it to the window. "A bottle of soap. Perhaps we can use it as lubricant and slick you up enough so you can squeeze through!"
Rainbow halted her struggles and shone up. "Hey, nice! Well, slap it on me already so we can get going! I don't to be in here a second longer."
"Well, I wish I could do that, but..." Twilight started and looked at Rainbows hips again. "...I believe we're going to have to pull you back a bit so we can cover your hips completely. Otherwise we'd still get nowhere."
Rainbow shrugged, although Twilight would not be able to see it. "Sure then, let's just get..." she said and tried to push herself back. All she could feel however, were her hips painfully squashed by the window. She tried fitting back a couple more times but without any success. "Shit." she whispered to herself. "Uh...Twi'? Could you give me a hand?"
"Sure!" Twilight replied and immediately went up to the window, beginning to pull Rainbow's swimwear back through the window and pulling her legs slightly.
Rainbow felt more and more of her butt slowly squeeze back into the underground room and tried again to wiggle her hips backwards. This time, she managed to force herself backwards more and more until her entire hip region fell out of the frame and she landed on her stomach. Her hips felt sore after her time inside the window.
"Alright, good." she could hear Twilight say from the inside. "Now let's just rub this on..."
The violet mare popped open the bottle and poured som of its contents on her hands before rubbing it on Rainbow's rear. The female being just sat and waited patiently in the window. After a while, almost all of the bottle had been emptied, and Rainbow Dash's entire bottom was soaked in the cleaning substance.
"There we go." Twilight called out.
"About time." Rainbow muttered and pushed forward again, immediately having her hips budge on the edges. Almost immediately she could feel her friend's hands plant themselves on her hips, helping her to press on forward.
Rainbow's hips and big butt slid in far easier than before, but both girls still had to struggle a bit to force them in. The mare in the window pushed hard against the wall, wiggling her rump through piece by piece whilst her friend behind her pushed on, forcing the soft buttcheeks into the frame. After a while of pushing, including Rainbow once again pulling on her bottom-piece, her lubricated derrière was wedged inside the window, refusing to budge forward.
"This is where we stopped last time." Twilight said and wiped off a bit of sweat on her forehead. She looked at her squirming friend in the tight square, the lubricant on her butt reflecting some of the interior light. "Focus on the hips, alright?"
"Hhng...yeah, yeah! Just push already!" Rainbow Dash called back, trying to wiggle herself through prematurely.
Twilight nodded. Here goes nothing... she though before leaning in on the almost bare rump in front of her. The stuck mare pushed as hard as she could at the house wall, twisting her body in an attempt to free her hips. She grabbed the left side of her swimwear with one hand and pulled hard, the fabric stretching to its maximum.
"Come on, come on..." she whispered, inching her hip further and further through.
Meanwhile, Twilight kept pushing Rainbow's butt, but realized pretty soon that she still wasn't moving. The widest part of the cyan female's hips were completely blocking the tiny window, and she could hear its owner's grunts from the outside as she was struggling to fit it through. Determined to help her friend out, Twilight mustered up her strength again and lifted up Rainbow Dash's legs instead, holding them in the same level as the window and pushed forward.
Rainbow felt what Twilight was doing and began wiggling even harder, feeling her ass slowly creep through the frame, thanks to the lubricant. She was pushing the wall so hard now that her wrists almost threatened to snap. As if automated, both girls slowly changed their strategy from pushing normally to small, quick bursts forward, edging Rainbow closer and closer to the exit.
Come on, squeeze! Squeeze! Rainbow though desperately, tears nearly forming in her eyes. Her hips were now right at the outside edge of the frame. She could even see the top of the crack between her tight buttcheeks.
Finally, after one big thrust from Twilight's end and with one large push from the stuck mistress, the widest part of Rainbow Dash's hips inched through the frame. She let out a grunt of relief and pushed again, squeezing the rest of her large rump out, before slumping down on the soft grass. Inside, Twilight stepped back, panting slightly from the effort.
Both of them rested for a couple of seconds, before Rainbow Dash slowly rose to standing position, rubbing her aching hips and covering her hands in the soap covering them. "Whew, that was a toughie." she panted and leaned down to look through the window she'd just squeezed through at Twilight.
"True. Now, could you get me out of here? I don't want to pull the same stunt you just did."
"Oh, right." Rainbow said and grinned, pulling the bottom-piece out from between her buttcheeks before taking off towards the door leading to the basement. Twilight went over to stand right by it, soon hearing the sound of her friend's naked feet moving down the stone staircase. A few moments later, the broken doorknob turned and the door swung open, revealing a content Rainbow Dash. "That wasn't too bad now, was it?" she told Twilight, arms crossed nonchalantly in front of her.
The purple mare scraped her foot against the floor and simply let out a small 'heh' in reply, hands behind her back and smiling sheepishly. Her friend rose an eyebrow, waiting for any other response. When it didn't come, she scrunched her lips and let her arms just hang. "Alright, I didn't actually know my ass was going to get me stuck." she said, placing one hand on her hip and looked back at her wide posterior.
Twilight let out a tiny giggle. "We still made it through, right?" she said placing a hand on Rainbow's shoulder. "Imagine if I would have tried doing  that. I probably would not have gotten my chest through!"
At this Rainbow chuckled. "Nah Twi'. Your boobs would have gotten through just fine. I would be a little more worried about this fellow." she said and reached out a hand to stroke Twilight's back, moving over a piece of the purple mare's hip and one of her large buttcheeks. "It's bigger than mine, so if you though I had trouble, man, you'd be stuck forever!"
The larger female moved away slightly from the caressing, a blush showing up on her face. "Rainbow! Haven't you heard of sophistication?"
"What?" the blue mare asked. "You didn't have anything against feeling me up before, right?"
"That was different, it was necessary!"
"Esh, come on. I'm just teasing with ya'. You're sounding like Rarity." Rainbow said and looked to the top of the stairs. "Come on now, wasn't there a beach to get to?"
"Oh, right! I almost forgot about that." Twilight exclaimed and looked out the basement window. Luckily, the sun still stood high in the sky, so there was still time to spend outside at the shore. Neither of the mares said anything else as they exited the room. Rainbow charged up the stairs whilst Twilight took one last look at the squares in the wall, before switching off the lights and closing the door.
