  1. >Starlight collapsed onto the couch as she returned home one evening
  2. >she was sweating profusely, every muscle and bone ached
  3. >these exercise routines were the absolute worst!
  4. >but the alternative was plain; the years rolled by, and she wasn’t young enough to just eat whatever she wanted
  5. >just a year prior, she suffered the biggest embarrassment when her best shirt’s topmost button snapped off and hit Celestia during a high society party
  6. >then it was from embarrassment, and today it was how she physically felt
  7. >as she moaned, ”I’m literally going to die!”
  8. >Trixie snickered
  9. >and that gave Starlight enough energy to lift her head and glare at her roommate/friend-with-benefits/pain in the ass sorcery student
  10. >”The heck are you laughing at?” Star growled
  11. >Trixie sat, munching on a huge bowl of a poorly conceived breakfast cereal of Pinkie’s design that was predominantly sugar
  12. >lightly seasoned with oat flakes
  13. >and she was even following Pinkie’s even worse conceived suggestion of using chocolate milk
  14. >”The Great and Powerful T-rrrixie is simply laughing at the jokes on this cereal box!”
  15. >Star thought to herself, ‘wait for it…’
  16. >”Also the state you keep returning home in. You look ridiculous! All that effort and you’re not getting slimmer.”
  17. >Star forced herself to her feet and stood over her so-called friend with the dreaded judgemental arm-fold pose
  18. >”I’m not *trying* to get slim. I’m building muscle. Lean muscle helps keep fat at bay by boosting the metabolism. Besides, you realise one of these days your *own* metabolism’s going to crash and burn too, Trix. And when it does, and your ass balloons until you’re suddenly the Fat and Flabulous T-rrrixie, don’t come crying to me.”
  19. >since she was already standing, she figured she’d do some wind-down stretching
  20. >and Trixie watched on with glee as she got an eyeful of Starlight’s jogging spats-clad thighs and ass as she bent down and touched her toes
  21. >she poked fun, but Trixie *really* liked what all her roomie’s efforts was doing to her body; an underlying meaty thickness and little bumps and divots of muscle forming
  22. >but it way *way* too much work
  23. >The Svelt and Sultry T-rrrixie was still flat bellied, wide hipped and, not to put too fine a point on it, a Perfect and Perky Poster-rrrier
  24. >and she had perfectly formed boobs
  25. >still, Trixie didn’t have a heart of stone, and she’d had her fun
  26. >… and more to come later as she continued to watch Star finish her post-exercise stretches
  27. >she said, “So The Wily and Opportunistic T-rrrixie has convinced Applejack to sell her one of her special bottles of hard cider in agreement for me to performing at her next family gathering.”
  28.  
  29. >Trixie then presented the large bottle of rare as hens teeth and hard as a diamond alcohol
  30. >Star paused and her jaw went slack. “Wow, that *is* impressive! We should save this for Hearthswarming.”
  31. >Trixie huffed. “Heck no. I’m popping this open tonight.”
  32. >”You realise it’s the running of the leaves tomorrow, right? We can’t be drinking the night before we both intend to spend the hours jogging. Not to mention that you *swore* you’d join in *and* claimed we’d come in the top ten.”
  33. >”I do, we can, I did and we shall! The Great and Powerful T-rrrixie may not be *quite* as fit as her bestest of best friends, Ms. Glimmer, but I can easily see you in third behind Dash and Applejack, and me in a very impressive fourth!”
  34. >Star pouted. “The only running you do is *away* from trouble and *towards* performance venues, and only when you’re running late. This is an endurance run! I’ve been telling you to take it seriously for weeks!”
  35. >”Trixie’s going to open this bottle now. Whether her grouchy and miserable friend also enjoys some of the finest hard cider in all of Equestria or not is solely in her hands…”
  36. >Trixie popped the cork, and the smell of sweet apples and strong alcohol filled the room
  37. >Starlight frowned and sighed, then went and got two glasses. “Just a couple.”
  38. >”Whatever you say, Star.”
  39.  
  40. >waking up next to each other was typical
  41. >even being in a tangle of limbs
  42. >the throbbing heads was less so
  43. >”The Grave and- *ulp* Palpable Trixie wishes for death…”
  44. >”Ugh… less long words. Or any words.”
  45. >Starlight sat up and squinted at the evil, *evil* sunlight pouring through the window
  46. >what time was it?
  47. >there was a knock at the door
  48. >”Hello? Starlight Glimmer and Trixie Lulamoon? It’s Mayor Mare. The running of the leaves begins soon and we need all participants signed in within the next half-hour.”
  49. >Starlight launched herself to her feet
  50. >and promptly faceplanted as nausea and still-lurking alcohol flowed through her system
  51. >the second attempt fared better as she helped herself up with the wall
  52. >”Just don’t bother going,” Trixie mumbled
  53. >”I’m not letting you skip this, Trix. You promised me!”
  54. >Trixie suddenly sat up and hauled herself out of bed. “Yes! I’m up!”
  55. >she blinked and scratched her head
  56. >”What the heck!?”
  57. >”Glad you agree.” Starlight said as she guzzled some water and some homemade hangover cure powder, and offered the same to Trixie
  58. >”I don’t feel well…”
  59. >”Nor do I, but this’ll help.”
  60. >the magician nonetheless took the water, downed the powder, then immediately started getting ready
  61. >within fifteen minutes, they were both dressed and…
  62. >well, by their lidded, dark eyes and pale complexions, *ready* wasn’t the right word
  63. >but they were soon out and up at the gathering station at the forests edge, just in time to finish their registration
  64. >”I’ve *so* got this,” Dash said, sprinting on the spot at full pace so fast she was kicking up a dust-cloud
  65. >as usually, the short girl was slim, powerfully built but compact and was the perfect fit for the event
  66. >”Sure, burn yourself out, string-bean,” Applejack said with a chuckle
  67. >she was gently warming up her tall, big, curvy, brawny body with push-ups, sit-ups and slow jogs back and forth across the waiting area
  68. >Twilight was sticking to stretches, her long limbs and princess-powered perfectly balanced physique taller than even Applejack
  69. > and she waved to Star and Trixie, but the glowing smile shifted to concern
  70. >”Good morning… I hope?”
  71. >Star offered a polite wave back, but Trixie groaned
  72. >”It most certainly is not a good morning…”
  73. >”But we’ll make do,” Star added, then insisted, “*right?*”
  74. >Trixie stood up straight and suddenly saluted. “Yes ma’am!”
  75. >she then relaxed and looked concerned. “The heck was that? What’s wrong with me?”
  76. >”There’s no shame in stepping out if you’re not well,” Twilight offered
  77. >”Don’t encourage her to quit, Twi. She promised me we were going to compete.”
  78. >”Exactly! Like she said,” Trixie said, then frowned and looked confused
  79. >”That’s what I like to see, Trixie,” Dash said and slapped her on the back. “To hay with any ouchies or upset stomachs. Dig deep, fight through the pain!”
  80.  
  81. >Mayor Mare climbed the small stage and pulled out a megaphone. ”Could all competitors please make their way to the starting line!”
  82. >begrudgingly, Trixie and Starlight joined the bright-eyed citizens of Ponyville
  83. >”And most of all,” the Mayor continued, “have fun!”
  84. >”I didn’t realise torture would be considered fun,” Trixie grumbled
  85. >”Could you stop complaining? Just focus.”
  86. >Trixie clammed up and got ready
  87. >”Three, two, one, go!”
  88. >the crowd settled off into a jog
  89. >all the more athletically inclined citizens quickly found themselves out front
  90. >Starlight settled in for the long haul as her medicine worked it’s (literal) magic, taking the sting out of her hangover and easing her stomach
  91. >although not having eaten breakfast, she knew she was going to be in trouble
  92. >Trixie was already hitting the wall, but felt compelled to keep struggling
  93. >the powder helped but as she tried to keep pace with Starlight, her shortcomings became *very* apparent
  94. >the regular citizens started overtaking
  95. >Trixie pushed harder, but stumbled
  96. >”C’mon, Trixie!” called out Starlight
  97. >the magician couldn’t answer, she was gasping for breath
  98. >and Starlight was focused on her own condition, breathing and pace
  99. >it became easier for the prodigy as she watched the leaves fall with the thundering of Ponyville’s feet
  100. >she soon came to enjoy the run
  101. >but after the hour long event drew into its final stretch, the lack of fuel kicked in
  102. >Star slowed, and was overtaken
  103. >but managed a respectable seventh, before promptly collapsing into a pile of leaves
  104. >once she wasn’t in danger of passing out, she watched the finishing line
  105. >Trixie wasn’t anywhere to be seen
  106. >more and more people poured through
  107. >then the stragglers
  108. >then, finally, Trixie appeared
  109. >held piggyback by Derpy
  110. >Starlight had recovered enough to meet her at the finish line
  111. >she wasn’t as angry as she could have been
  112. >just disappointed
  113. >”Well, fourth was right,” Star said
  114. >Trixie, pale faced and looking sick, give Starlight a confused look
  115. >”Fourth to last, I mean. Thanks, Derpy.”
  116. >the screw-eyed postwoman saluted. “She was in safe hoo- uh, hands!”
  117. >Derpy dropped Trixie off, and she finally walked past the finish line before Granny Smith, Cranky Doodle and a crutch-using, hobbling Bulk Biceps finished too
  118. >but as soon as she did, Trixie felt a jolt run through her
  119. >as did Starlight
  120. >and a magical swirl of energy formed between them, before fading
  121. >they both cried out, ”what the hay was that?”
  122.  
  123. >Trixie went straight home, feeling miserable and drained
  124. >while Starlight went out to order some food
  125. >her annoyance had been plain, and she voiced it clearly but calmly
  126. >after all, Star didn’t want a repeat of the whole bottle incident
  127. >”I’m disappointed, but what’s done is done.”
  128. >as usual, when push came to shove, such remarks hurt Trixie more than she would ever admit
  129. >but it would be fine, they’d had plenty of these bumps in the road this before
  130. >and on Star’s return, she had several bags from the burger place Twilight loved so much, and Trixie perked up
  131. >”Woo! That’s what I’m talking about! Real food! Less ‘quinoa this’ and ‘kelp that’.”
  132. >Star thrust one bag into Trixie’s hand, and kept four for her herself
  133. >with a raised eyebrow, Trixie dug out a single meal and soda
  134. >while Star unpacked hers; several meals, two shakes, a giant soda and a family sized tub of ice cream
  135. >Trixie held out her hand to take her extra share, only for Star to bat it away
  136. >”Mine. You’ve got yours.”
  137. >Trixie dig into her burger. ”So much for the diet and exercise, huh?”
  138. >Star demolished her first in seconds. ”I’m punishing myself.”
  139. >Trixie rolled her eyes. ”Seventh isn’t *that* bad.”
  140. >”Not for my performance, Trix, but for letting you talk your way out of practicing and talking me into drinking. I’m going to binge until I can’t eat any more and feel sick, regret my decisions, and work off every single calorie to make sure I don’t fall for your crap again.”
  141. >Trixie felt bad again, but she only agreed to join in with the stupid run to get Star off her back
  142. >… and, maybe, because she just enjoyed spending time with Star, and she was feeling left out of all the extra time she spent exercising
  143. >but as usual, Trixie couldn’t help but feel like Star wasn’t being fair
  144. >”Right, sure,” Trixie said with a huff. “I’m everything wrong with your life.”
  145. >”And here comes the victim game again!”
  146. >the pair glared at each other
  147. >then just silently ate
  148. >Star was seriously pigging out
  149. >Trixie was surprised at just how much she was packing away, then Star even seemed worried too
  150. >she had just eaten he fourth full meal
  151. >”How am I still not full?”
  152. >before any answers could be given, there was a knock on the door
  153. >Star stood to answer
  154. >while her roomie’s back was turned, Trixie stole herself another meal and crammed it down before her roommate even reached the door, and guzzling down some of Star’s huge soda as the door was opened
  155. >”Oh, hey, Twilight. What’s up?”
  156. >”I just came over to retrieve the Book of Bonds and Bindings. Thanks for looking after it for me. Oh, and hi Trixie. Hope you’re feeling better.”
  157. >Trixie went to respond, only to feel a shiver run through her and a heavy pressure in her stomach
  158. >Star gasped and shuddered as well, and frowned down at her well toned midsection as she rubbed her belly
  159.  
  160. >Twilight looked at both of them. “Do you girls want me to call the doctor? Between earlier and the way you’re both looking now, I’m getting worried.”
  161. >”The Great and powerfu*uooUUURP*!”
  162. >Trixie clapped a hand over her mouth
  163. >sweet Celestia, that was loud!
  164. >”Uh… excuse me.”
  165. >”That certainly was great and powerful, alright,” Star said with a smirk. “Maybe try not stealing my soda when my back’s turned, Trix.” Star then turned to their friend. “And no, Twilight, I’m sure we’re both fine.”
  166. >”*ahem* as I was about to say, The Great and Powerful T-rrrixie was just having an off day. I can’t be amazing *all* the time.”
  167. >Twi shrugged. “If you’re sure.”
  168. >”Anyway, let’s go find that book. Now, where did I put it…”
  169. >Twilight and Star entered her bedroom and left Trixie to fight down the blush from her gastric outburst
  170. >the pressure in her belly continued to mount
  171. >she rubbed her stomach and groaned as it, too, violently burbled
  172. >then another shiver ran through her
  173. >the pressure shifted… mostly lower, but it seemed to spread
  174. >why was her butt tingling?
  175. >Trixie stood up and headed for the bathroom, and looked herself over
  176. >she still looked a little pale
  177. >did something just move?
  178. >Trixie looked down
  179. >then turned to the side and removed her skirt
  180. >her sexy and seductive panties really emphasised her butt, and she grinned as she felt her posterior
  181. >perfectly padded yet tight
  182. >she then gasp as she watched and *felt* her ass, hips and thighs suddenly swell out
  183. >her butt alone grew by about three inches
  184. >closely followed by her boobs grow by an inch
  185. >finally, even her belly gained a little subtle padding as, with a final rumble and tingle, the pressure abated
  186. >”M- maybe Star’s right. Maybe my metabolism’s breaking down…”
  187. >she stripped down and gave herself a once over in the mirror
  188. >weird as it was, she wore the weight well at least… she looked extra curvy
  189. >”Trix?” Star suddenly called out through the door. “You weren’t going anywhere today, right? I’m heading out for a couple of hours and I need you to keep a eye on those other artefacts!”
  190. >Trixie panicked for a moment and put on her underwear, then reached for the door handle
  191. >”Wait!”
  192. >the house door closed; too late
  193. >”Damn it.”
  194. >she left the bathroom, sat down and, still feeling a bit strange, decided to stay put
  195. >by way of taking a nap
  196.  
  197. —
  198. >”I have no idea what happened,” Starlight said as she and Twilight studied the Book of Bonds and Bindings. “I swear, I never wrote this.”
  199. >Twilight shook her head. “I believe you, but that’s the problem; this book doesn’t just respond to writing. It can be activated by verbal contracts as well.”
  200. >Starlight gulped as they both stared at the page in the magic book
  201. >scrawls, symbols and musical notes were strewn about
  202. >they glowed and changed colour
  203. >Starlight didn’t remember much about last night
  204. >but any time alcohol and Trixie was involved, it usually ended with angry words, angrier sex and a more level headed morning-after apology and cuddle session
  205. >she hated how much she loved Trixie sometimes
  206. >”So how do we work out what it says?” Star asked
  207. >”I can translate it, but it will take time. We can instantly replay the contract spoken if particular phrases are repeated in its presence. Any idea what you might have said?”
  208. >Star shrugged. “No idea.”
  209. >”It could have been any incidental conversation so long as it contained some sort of agreement or contract. For example; if you pass me that book,” Twilight said and pointed to a nearby notebook. “I’ll shake your hand.”
  210. >the magic book glowed, turned a new page, and more notes and glowing symbols appeared
  211. >Starlight shivered, much like she kept feeling earlier, gingerly picked up the notebook, and handed it to Twilight
  212. >then, Twilight shuddered too, and both magically gifted girls were compelled to shake hands
  213. >the symbols faded, and the page was empty once more
  214. >”Until I can get this translated, I’d be careful about what you do, Starlight. If you think of anything that could help, let me know. Otherwise, I’ll get on with translating and get back to you if I can glean anything else.”
  215. >Starlight sighed and clutched her head
  216. >what a mess…
  217.  
  218. >Starlight left Twilight’s palace, and went for a walk
  219. >she hadn’t fulfilled her pigging out session, but she didn’t feel like it anymore
  220. >she could eat, strangely, but she wanted to meditate and try to remember what had happened the night before
  221. >they had been discussing the running of the leaves
  222. >Trixie was being difficult, as usual
  223. >Star knew she mentioned she wished she had Trixie’s lackadaisical ability to just eat everything she wanted
  224. >… if the book overheard that, it would explain why she was able to eat so much earlier, yet felt nothing afterwards
  225. >she just might have Trixie’s seemingly flawless metabolism!
  226. >but what would she have said?
  227. >”Howdy, Starlight!”
  228. >a familiar voice broke her focus, and she turned to see a familiar face wave her down
  229. >”Hey, Applejack. Great job on winning the running of the leaves! You were unstoppable today.”
  230. >the farm girl blushed. ”Aw, shucks. That’s mighty kind of ya, but it ain’t about the competition. We’re all doin’ our part to shake the leaves to roll in fall. Y’all did pretty good yourself, even though ya didn’t exactly look your best.”
  231. >”Self inflicted issue, that’s all, but thanks.”
  232. >Applejack looked across at Starlight’s home. ”All the same, is Trixie okay? She wasn’t lookin’ well earlier.”
  233. >”Again, self-inflicted. We’re quite the pair when it comes to messing up and having to learn hard lessons from the fallout. She’ll be fine.”
  234. >”I was about to go invite you both to Sweet Apple Acres; we’re havin’ a thing to celebrate the fallin’. Y’all wanna go invite Trixie? It only feels right.”
  235. >Starlight glanced at her home; it was time to prove a hypothesis, and teach Trixie a lesson at
  236. >”Best not disturb her. She still wasn’t feeling well, but I’d love to! I’ll bring her something back so she doesn’t feel left out.”
  237. >”Well, come on over then! No time like the present.”
  238. —
  239. >Trixie yawned and sat up
  240. >she definitely felt better after that nap, though a quick feel of her inflated rump proved that, yep, that was still a thing
  241. >… as nice as she wore the weight, she was wondering if maybe she should start joining Starlight in her exercises
  242. >she began dreaming of herself, toned thighs and a little bicep action
  243. >”The Fit and Fabulous T-rrrixie does have a certain appeal.”
  244. >no time like the present!
  245. >she knew the artefacts Starlight was examining were important
  246. >and with incorrigible idiots like Snips and Snails around, not to mention the too curious for their own good CMC, The Mature and R-rrresponsible T-rrrixie wouldn’t leave until Star got back
  247. >she did still feel cruddy for insisting they drink, after all
  248. >so Trixie settled into some exercises here
  249. >stretches first!
  250. >bending here and there, pacing around the house
  251. >she felt a shiver, and a budding pressure in her gut
  252. >”Oh, what now?”
  253.  
  254. —
  255. >Applejack wasn’t even eating anymore
  256. >she watched, slack jawed, along with Dash, several other of the runners from earlier, and the Apple family, as Starlight gorged herself like she hadn’t eaten in weeks
  257. >”It’s all so good!”
  258. >whole pies, dozens of fritters, piles of cupcakes
  259. >oh, it was amazing!
  260. >and she didn’t feel a thing!
  261. —
  262. >”No, stop! Not again!”
  263. >Trixie’s stomach churned and groaned
  264. >and the tingling and pressure in her stomach intensified until it was painful
  265. >then it burst
  266. >like last time, it focused downward, but spread through her body
  267. >her ass suddenly shook and quaked
  268. >Trixie ran to the bathroom mirror just in time to watch her panties strain as her ass bulged against them
  269. >”No, no, no!”
  270. >*SNAP*
  271. >her butt exploded through the already fully packed garment
  272. >and her cheeks jiggled and swelled out until they were easily twice the size as before, spread across door-frame wide hips and Applejack-shaming thighs, but without the underlying muscle; just plush softness
  273. >her belly then flubbed out a couple of inches, becoming just short of flabby
  274. >then that was overshadowed by her breasts filling out, growing into overflowing handfuls, although her bra managed to weather the onslaught of titflesh
  275. >Trixie stammered as she looked herself over and felt her expansive curves
  276. >she *hated* that she kind of liked how she wore the weight
  277. >but there was no way any of her clothes would fit!
  278. >she couldn’t just turn up to a performance in any old outfit!
  279. >half the mystique was the outfit, and they had to be form fitting!
  280. >lure the eye to Trixie and not the trick, that was her motto
  281. >though… she certainly would stand out-
  282. >”Trixie! I’m back! You okay? I brought you some absolutely amazing food from Applejack’s place!”
  283. >Trixie wrapped a towel around herself as best she could, and opened the door
  284. >”There you-“
  285. >Starlight’s eyes went as wide as Trixie’s butt as the magician struggled through the doorframe
  286. >then she blushed and gulped
  287. >”oh… wow.”
  288.  
  289. >”Don’t ask! I don’t know and I haven’t touched anything!” Trixie squeezed her ass and bit her lip. “I only just woke up from a nap.”
  290. >Star continued to stare, red faced, at Trixie’s amazingly plus body before she finally said. “You haven’t been eating anything, have you?”
  291. >”Not since the burgers earlier. I haven’t even picked at your leftovers, I swear.”
  292. >Star approached and put an arm around Trixie’s shoulders. “It’s alright, I believe you. It’s probably tied to the book. Twilight said we might have triggered a verbal contract. You don’t remember anything like that, do you? It could be anything.”
  293. >the physical support helped calm the magician down. ”The Ailing and Out-of-sorts T-rrrixie remembers a lot of things, but no. Last night is a blur.”
  294. >Starlight glanced behind her friend and couldn’t fight off the smirk as she stared at the sheer size of dat ass
  295. >”Well, if you do, just tell me. In the meanwhile…”
  296. >she grabbed a handful of jiggling, smooth and pliable booty, and Trixie gasped
  297. >”I’ve gotta say, this isn’t a bad look for you, Trix. Maybe your fast metabolism is more of a curse than a blessing.”
  298. >”Trixie… kinda, sorta agrees, but all the same, I still prefer being slim. The Flippant and Hindsight-Considering T-rrrixie is coming around to the idea of going with you on your exercises.”
  299. >”Okay, that’s fine. But…”
  300. >Star stroked her friend’s pudgy belly and leaned closer, whispering and purring into Trixie’s ear
  301. >”…it could be this ample and sexy form of yours is temporary. Maybe we could have some fun before Twilight works out the contract?”
  302. >Trixie gulped as Star continues to stroke and rub against her enhanced curves. “Yeah… it would be a waste.”
  303.  
  304. >the pair took it into Starlight’s bedroom, and climbed into bed
  305. >Trixie removed her bra, and her confined bosom was unleashed
  306. >they were as big as her head!
  307. >they hung over her subtly rounded, soft belly in a perfect blend of curves
  308. >naturally, the real main event was Trixie’s colossal ass
  309. >Starlight immediately took the opportunity to bury her face between her cheeks, wrapped her arms around the huge swells, and pulled them together
  310. >it was like a giant marshmallow with the plushness
  311. >Star moaned as she was enveloped in the warm, smooth and borderline spherical bliss
  312. >Star could have stayed here all night…
  313. >”I get it, the Thicc and Full-figured T-rrrixie is to be adored and admired, but come on!”
  314. >reluctantly, Star complied, and climbed back over to Trixie’s pretty face and still respectably enhanced bust
  315. >the pair began to stroke, grope and kiss
  316. >it was an exciting change of pace to have Trixie, usually the weaker of the two, put her extra weight to work
  317. >and definitely more of a challenge, and Trixie soon found herself on top of the fitter, slighter woman
  318. >Trixie then pushed her tits in Star’s face, and pulled her in a tight hug
  319. >she then slid one of her legs between Star’s own, and the pair began grinding
  320. >which gave Star a great opportunity to reach around for more rear groping as they moaned
  321. >she couldn’t help but be amazed at how she couldn’t reach all the way around her kinda, sorta girlfriend’s body
  322. >Trixie was so much woman!
  323. >but she also couldn’t help but worry Twilight would solve this situation before Starlight got what she was *really* after
  324. >”Wanna put that ass to good use?”
  325. >”Trixie’s listening…”
  326. >”Sit on my face and I’ll lick you until you scream… over and over and over!”
  327. >Trixie but her lip and giggled. “Trixie can definitely get behind that.”
  328. >”Oh, I’ll get behind, alright…” Star whispered and licked her lips, slapped Trixie’s ass with a thunderous clap then narrowed her eyes. “I’ve just got to do one little thing first. How about you eat that pie I brought you from Applejack’s? And maybe you could put on that sexy-as-hell, lacy gown?”
  329. >”Trixie wouldn’t normally want to eat in the middle of playtime.”
  330. >”Oh, I just don’t want to be the only one doing the eating…” Star tan her fingers up Trixie’s shoulders and gave her the ultimate fuck-me eyes. “And I’ll be at it for some time. All night, if it’ll please you.”
  331. >Trixie gibbered and her heart raced; sweet Celestia, she hadn’t seen Starlight so horny in a long time!
  332. >”Deal! See you in ten minutes!” Trixie climbed off, and Starlight enjoyed watching all that flowing, juggling booty as Trixie walked away
  333. >Starlight teleported herself on some clothes, all the bits she had in her savings, then teleported herself to Sugarcube corner
  334.  
  335. >a shocked Mrs. Cake yelped, blinked, then said, “oh, good evening Starlight. We’re technically closed…”
  336. >she was in the middle of putting everything into storage
  337. >Starlight threw her bits on the counter with a heavy thud
  338. >”I’ll take *everything* you have!”
  339. >she didn’t wait; she used her magic to take every cake, piece of bread, cookie, pastry and more and floated it together
  340. >she then strained as she compressed it all into a super-dense, sweet singularity as big as a regular piece of candy, then licked her lips
  341. >Mrs. Cake’s eyes went wide. ”I don’t think that’s a very good idea, Starlight!”
  342. >”Probably not!”
  343. >she floated it into her mouth, and swallowed it whole
  344. >”But she… uh, *this* is going to be huge!”
  345. —
  346. >Trixie finished her treat
  347. >she kind of regretted it, as today had made her wary of eating anything else, but screw it, that pie *was* delicious
  348. >a message teleported in with a familiar pink flash
  349. >Trixie floated it over and read it
  350. >’Starlight, make sure neither of you eat anything! I’m still translating the contract, but anything you two eat is being multiplied and transferred directly as some sort of mass into Trixie! Something about you “betting her ass” about coming in the top ten at the running of the leaves? Just to play it safe, I’ve managed to add a contingent overlap spell that should stop Trixie from suffering any undue effects from the contract by balancing the focus of mass. I should have it all solved by morning. Be safe, Twilight.’
  351. >Trixie scowled
  352. >Starlight knew what was happening to her and was taking advantage of it!
  353. >she hid the scroll away, and eyed the leftovers from earlier
  354. >two could play at this game…
  355. >she tore into the cold food greedily, then raided the fridge, emptying that too
  356. >she groaned as her stomach gurgled from the binge, but it settled just as Starlight teleported back in
  357. >”Sorry about that! I forgot I had to talk to Twilight about something,” Star said and wiped her mouth
  358. >Trixie smirked and did the same. “I’ll *bet*. Oh, but where were we?”
  359. >she headed for the bedroom, and grinned as she felt that familiar pressure begin to build
  360.  
  361. >”Your throne awaits, my lady,” Trixie said and gestures to the bed
  362. >Starlight lie flat across the bed, face up, near the edge
  363. >and with a flash of magic, she was naked
  364. >”And *your* throne awaits, my lady,” Star said with lidded, eager eyes as she gestured to her face
  365. >Trixie giggled and approached, then felt a tingle run through her so strong she gasped and stopped in her tracks
  366. >she then patted her stomach as it loosed an especially deep, long and unsettled rumble
  367. >both of them couldn’t help but let a little worry slip into their expressions, about how big she was about to become, but when their gazes met, it was all sultry smiles and they winked at each other
  368. >Trixie turned, wiggled her rump, and slowly lowered herself over Star’s face
  369. >the prodigy trembled with excitement as the gigantic, looming ass soon took up her whole view
  370. >then the eager, wet lips between Trixie’s legs, spread and waiting, took centre stage
  371. >Star took a deep breath, and her own arousal peaked as that meant she got a huge whiff of Trixie’s juices
  372. >then they made contact
  373. >Star was utterly enveloped in soft, plush booty fat
  374. >then Trixie’s full weight was applied
  375. >the bed creaked
  376. >Star’s face was buried deep in Trixie’s pussy
  377. >and as her senses were overwhelmed, she just ran on instinct
  378. >and plunged her tongue deep inside
  379. >Trixie immediately gasped and tensed up as Star began licking long, deep and familiar
  380. >Star knew Trixie inside and out, and it showed as Trixie’s cries rose in pitch and intensity
  381. >and then with a shrill scream, she came
  382. >Star was sprayed with Trixie’s femcum
  383. >then Trixie, even through the intense climax, shuddered as she realised the pressure inside had just burst
  384. >the power mostly spread lower, like normal
  385. >Trixie’s ass swelled, smothering Starlight until only her legs were visible
  386. >and, as before, her belly and boobs tried to grow out as well
  387. >Starlight was also overwhelmed by just being smothered by more and more Trixie
  388. >her magic flared up and pulled one of her toys from a nearby drawer
  389. >and plunged it into her own womanhood
  390.  
  391. >but then Twilight’s contingency magic kicked in
  392. >more power was pulled from Trixie’s inflating ass
  393. >Trixie couldn’t tell what was happening as she was still deep in the dopey afterglow
  394. >things were getting… lower?
  395. >her legs spread farther along the floor
  396. >the bed’s creaks turned strained and stressed
  397. >Starlight’s own climax rang out as she screamed, muffled deep within and under Trixie’s gigantic ass
  398. >the vibrations started Trixie’s second buildup of pleasure
  399. >and it was only then that she had the focus to realise what was happening
  400. >Trixie’s hair brushed the ceiling
  401. >her foot knocked into a dresser nowhere near the bed
  402. >and her lacy gown shripped and burst even around her shoulders
  403. >then one side of the bed gave way with an almighty crack
  404. >”I- I’m growing? Ahh-!” Trixie moaned
  405. >Starlight could only feel more and more ass smother her, unaware of the rest of the growing woman on top of her
  406. >only Star’s knees downward were exposed now
  407. >and she was concerned by the breaking bed, but to Star, it was just more indulgent ass covering her
  408. >it didn’t even register that Trixie’s sopping wet slit had grown more spacious
  409. >as Trixie fidgeted, Star got another lungful of air
  410. >she kept licking, while plunging her own toy inside herself
  411. >Trixie braced her arms on the wall and ceiling as she fought to find a comfortable position as her body continued to grow
  412. >more, and more, and *more* Trixie filled the room
  413. >the rest of the bed groaned and splintered
  414. >”S- Starlight! S- stop! Ahh-!! Oh fu-l”
  415. >the tiny woman was relentless
  416. >there was enough room that, despite how it should have clued her in, Star pulled her arms free from Trixie’s engulfing thighs, and pulled Trixie’s lips farther apart
  417. >and buried her head and arms inside, getting as deep as she could
  418. >”No! N- aaahhh!!!”
  419. >Trixie’s second climax literally shook the room
  420. >her feet smashed through the walls
  421. >her arms and head punched through the ceiling
  422. >and her all-encompassing ass smashed through their home
  423. >it was late evening, but the ruckus drew all eyes on Trixie as she tried to squirm free from the wreckage of Starlight’s home
  424. >the thirty foot tall, ultra curvy magician hadn’t even recovered from her second orgasm when Starlight’s relentless efforts only redoubled
  425.  
  426. >all her magic was being pushed into massaging and penetrating Trixie’s clenching inner muscles, rippling and quivering like a giant vibrator
  427. >the third and final climax rang out hard and fast across Ponyville with an almighty echo
  428. >and, at last, with a ground shaking rumble, Trixie collapsed with all her weight
  429. >she didn’t know how long she was numb from the overwhelming pleasure, but as embarrassed onlookers stared, another concern hit her
  430. >”Starlight?”
  431. >silence
  432. >she sat up, panicked
  433. >”Starlight!?”
  434. >still nothing
  435. >Trixie looked around, tears forming in her eyes and she frantically searched for her friend
  436. >then she felt a faint tap against her inner thigh
  437. >Trixie reached down and plucked a drenched, disheveled and bruised Starlight free
  438. >in a dazed, tired tone, she said, “did the earth just move or am I losing my mind?”
  439. >Trixie wept as she clutched Starlight against her cheek
  440. >”Thank Celestia you’re alright! I thought I’d lost you for a second!”
  441. >”I’ll be alright,” Star said and winced. “Kinda hurt all over though.”
  442. >in a flash, Trixie’s relief and joy spun into anger as she (gently) shook her friend
  443. >”You idiot! The Great and Gigantic T-rrrixie almost smooshed you like a bug because *you* were making her bigger without telling me what was going on!”
  444. >Starlight but her lip and couldn’t look Trixie in her giant, purple eyes
  445. >”Sorry… I was having a little too much fun with… well, all this.”
  446. >she gestured down to Trixie’s body
  447. >the magician stood
  448. >she hadn’t changed too much in proportion, although her ass *was* even bigger than before
  449. >just all tied to a thirty foot body
  450. >then the fact she was naked, and everyone was staring, sunk in
  451. >”Uh…”
  452. >Trixie covered herself as best she could
  453. >Star levitated some sheets and curtains to plug the gaps Trixie’s hands and arms couldn’t reach
  454. >there was a *lot* of Trixie to cover
  455. >Twilight teleported in, gawped at the scene, and pinched her brow as she growled with frustration
  456. >”Really? What were you two thinking!?”
  457. >the maybe/maybe-not girlfriends glanced at each other, and both grinned
  458. >”We weren’t?”
  459. >Twilight wasn’t impressed, and asked, “and what did you learn from this mess?”
  460. >Starlight scratched her head. ”That too much of a good thing has consequences on your health?”
  461. >Trixie patted her ass, sending a ripple along the building-sized mass that took a *long* time to stop jiggling. ”And that That over-indulgence is bad and can harm those around you, even if you don’t intend to?”
  462. >Twilight sighed and shrugged. “Sure, that works. Now let’s see about fixing this mess…”
  463.  
  464. >”We welcome you all back to a special do-over of the running of the leaves,” Mayor Mare called out
  465. >the town had once more gathered
  466. >only just before the start line was the giant Trixie, in a hastily sewn pair of shorts and a running top
  467. >”Just gotta come top ten to break the contract…” she said and stretched
  468. >she carried her weight easily enough, and having legs literally longer than people were tall?
  469. >coming top ten was all but certain
  470. >Twilight smiled up at her. “And everyone here is contracted to have their cardio work against your mass using the Book of Bonds and Bindings. You’ll be literally getting weeks of intense exercise in a few hours. My spell is still in effect, so you’ll shrink too, but I don’t know if it’ll be enough to get rid of all of it.”
  471. >”Be that as it may, The Vast and Voluptuous Trixie’s still somewhat torn about losing all this weight, but it’s been fun while it lasted.”
  472. >”It’s either that or you sleep in my barn, Sugarcube,” said Applejack, matter of factly. “And you work off the weight alone.”
  473. >”it’ll be fine, Trix,” Starlight said, bandaged and still bruised. “And I’m sorry for taking advantage of your situation. I let my excitement get the better of me.”
  474. >Trixie winked down at her, but couldn’t hide her shame. “And I should have just confronted you about it, like you have to my actions in the past. Sorry Star.”
  475. >she knelt down and they hugged
  476. >”Makeup sex later?” Star whispered
  477. >”You bet- uh…” they shared a look. “For certain!”
  478. >they shared a giggle
  479. >”On your marks!” Mayor Mare called out
  480. >everyone lined up
  481. >”Get set! Go!”
  482. >everyone ran and settled into a jog
  483. >but a combination of the jiggling ass and sheer width of Trixie meant overtaking was… frankly, too risky
  484. >and having been better rested and not nursing a hangover, Trixie made steady way through the already bare trees around Ponyville
  485. >Dash and Applejack once again took the lead, but everyone else kept a respectful distance
  486. >but Starlight, still injured, began falling behind
  487. >until Trixie slowed, picked her girlfriend up, and carried her the rest of the way
  488. >it was a unique experience; Trixie was shrinking as the run went on
  489. >and as she passed the halfway mark and was still twenty feet tall, she didn’t care if she was still huge or normal sized at the end
  490. >Trixie just had to admit, she was having fun with this exercise thing
  491. >maybe there would be room in the future for the Fit and Fabulous T-rrrixie!
