"I told you a million times already Bon, it's gonna be worth it!" Lyra smiled wide as she trotted through the busy main street of Canterlot, a reluctant Bon Bon following behind her. “It’s in this big library, I know it!”

“If you insist, Lyra...” Bon Bon grumbled and rolled her eyes, somewhat annoyed with Lyra’s usual antics, but at least finding some joy in the fact that she was getting to see Canterlot for once. She continued to follow Lyra through the streets, eventually coming up to a large and old-looking building; the two large statues of books at the front door making it quite obvious what the building’s purpose was.

Upon entry, the two mares were greeted with the sight of books, as far as they could see. With shelves upon shelves upon shelves containing thousands of books, this building had to be the most expansive library in Equestria. The specific book that Lyra was searching for was bound to be somewhere within.

With a bit of a frown, Lyra gulped, glancing around at the seemingly endless rows of books. “Oh...this place isn’t as small as I remember.” she glanced over at Bon Bon, smiling nervously. “I think we might be here a while!”

“Ugh...” Bon Bon groaned as she face-hoofed and shook her head a bit. "Well...we didn't come all the way up here for nothing, I suppose. Let's get started." she replied, before she slowly walked towards the desk in the middle of the room, glancing over the large book on top of it, labeled 'LIBRARY GUIDE'.

"Hmm...what's in here?" Bon Bon thought out loud as she flipped open the book, blinking a bit as it only seemed to have two pages. The inside of the book was merely two large pieces of wood, carved along the sides to look like paper. On the two 'pages' was a long list of sections for the library; Lyra curiously approaching the book as well and skimming over list until she spotted an entry, 'Magical Textbooks'.

"Ah, that's the section we need!" she smiled excitedly again before looking up at the signs on the ends of the bookshelves. "C'mon, this way!" she immediately took off down the long hallway, following the signs towards the section she was looking for, Bon Bon following closely behind her. Arriving at the correct bookshelf, Lyra looked up and down at the two shelves on either side of her, packed with large spellbooks. "Well, at least this narrows down our search a bit!" she giggled, smiling back at Bon Bon.

"I suppose...let's get this over with." Bon Bon replied before she started down the aisle, looking at the spines of the books. "What exactly are we looking for, anyways? You never told me."

Lyra rubbed her chin gently as she glanced over the wall of books as well. “It should be titled 'Everything you ever needed to know about Transformation spells'...odd, I know, but it's the book I'm looking for!" she giggled softly again, walking slowly down the aisle and looking over the title of each book. "Man, this place has so many spellbooks...wonder what else I could find in here."

About halfway down the aisle, Bon Bon stopped once she noticed a book title that was longer than the others, squinting and leaning her head in closer and seeing that it was the very book Lyra was searching for. "Here it is, Lyra." she called out, reaching a hoof up to pull it out from the shelf, but Lyra's magic aura had already surrounded the book and pulled it out.

"Ahh, finally!" Lyra smiled wide and giggled excitedly as the book levitated over to her and flipped open, the unicorn eagerly glancing over the pages, flipping them rapidly as she looked for a specific page. "All my research has finally paid off! Well, I hope!" she poked her tongue out a bit towards Bon Bon before looking down again, stopping about halfway through the book.

"Right...can I go now, Lyra? I want to see the rest of Canterlot." Bon Bon sighed softly, quite bored with the whole situation by now; seeming to be more of Lyra's usual 'human' antics.

Lyra smirked a bit in response though, her horn starting to glow with magic again. "Heh, you'll be able to see ALL of Canterlot with this spell, Bons!" she winked to the earth mare, before looking back down at the book again, reading the spell on the page it was opened to. "Let's see if it works, then..." she thought out loud as her horn began to glow brighter with magic, a second magical aura starting to surround her body.

"Huh...? What do you mean 'see all of Canterlot at once'? That doesn't..." Bon Bon raised one eyebrow, stopping her question as she noticed Lyra's body starting to change at a rapid pace. "What are you doing, Lyra?"

The unicorn groaned softly, feeling her body changing inside and out as the magic quickly took effect; her torso growing longer while her front legs slimmed down, their shape changing to resemble that of a primate's, with elbows, wrists, and most importantly, hands and fingers! While her transformation took place, Lyra leaned back and stood up on her back hooves as her skeletal structure changed to that of a bipedal creature.

Bon Bon gulped softly, backing up a couple steps as the unicorn's magic continued, blinking her eyes a couple times in disbelief. "Lyra! What is this? What's happening to your body?" she only became more concerned the more Lyra's body changed; her gaze shifting down to see that the unicorn's back hooves had changed as well, looking slightly similar to her hands, but longer and flatter, with shorter digits.

Only moments later, the transformation finally finished; Lyra sighing as her magic aura faded from her new body. "Ahh...did it work?" she opened her eyes again, now looking down at Bon Bon from her new height. She had to be at least six and a half feet tall; her body now very much resembling that of the "humans" that she studied so often, all except for smaller details that retained their original shapes, such as her ears, snout, tail and horn.

“I think...?” The other mare’s eyes widened to the sight before her; a tall, bipedal creature with a body unlike anything she’d seen before, though still retaining recognizable features of a pony. “Lyra, is that you? What did that spell do to your body?”

Lyra however was too busy marveling at her new body; grinning wide as she stared at her new hands, watching her fingers wiggle back and forth. "Oh my sweet Celestia, it actually worked!" she giggled excitedly, hopping up and down a bit, which inevitably caused the two sizable mounds on her chest to jiggle and bounce with her.

"Is that what you were trying to do, then?" Bon Bon looked down a bit as she saw the anthro mare's breasts jiggling all around. She blushed softly to the strangely arousing sight; the jiggling orbs reminding her of swollen teats. "Lyra, why are your teats way up near your head?"

Glancing down, the transformed mare continued to grin as she saw her well-endowed chest jiggling around, bringing her hands down and grasping at them. "Heh, oh wow...they're even bigger than I thought they would be!" she began to blush softly as well to the light tingles that the squeezes provided, while her gaze turned back to Bon Bon again. "Because that's where they are, on this body!" she explained, not quite noticing yet how Bon Bon seemed to be getting increasingly further away from her eyes.

"I see..." Bon Bon gulped softly and glanced over Lyra's body, finding the new look to be equally strange and intriguing, especially the anthro mare's jiggly chest. The sight of those two E-cups wobbling and bouncing lightly was almost hypnotizing to Bon Bon, her cheeks blushing a bit deeper as she kept staring.

"Hehe...somepony likes what she sees!" Lyra teased with a playful smirk, placing her hands on the sides of her breasts and squishing them together, while her horn began to glow again. "I'll give you a pair of your own to play with, Bons!" she poked her tongue out playfully, while her magic enveloped Bon Bon's body, glowing brightly as the transformation spell quickly began.

"Ahh, L-Lyra! Wait!" Bon Bon gasped as she felt the magic surround her body and begin to change her; morphing her body in the same way that Lyra's had, causing her to stand up on her back legs as well as the magic changed her body. Lyra giggled excitedly as it finished, immediately hugging and cuddling the other anthro-mare.

"Ooh, you look so cute, Bons! Though, uh...since when are you shorter than me?" Lyra blinked a bit, having to look down slightly for her eyes to meet the other mare's.

Groaning lightly, Bon Bon rubbed her head, still feeling a bit dazed from the sudden transformation, though her cheeks blushed from the feeling of her new breasts squishing against Lyra's, roughly the same size as well. "Ahh...Lyra...at least ask me before using your magic on me!" she looked back up into the unicorn's eyes with a slightly annoyed look, though the soft, tingly pleasure emanating from her chest sedated her a little.

"Heheh, you're gonna love it, I promise!" Lyra smirked playfully in return, leaning her head down slightly and nuzzling Bon Bon's snout, giving it a soft slurp. "I'll show you how useful hands can be, too!" she slid her hands down the other mare's body, enjoying the feel of her new fingers stroking over Bon Bon's soft coat and down to her waist. Both of them seemed to be slowly growing taller as well, Lyra's 6-foot height now approaching 10 feet, with Bon Bon only a little shorter.

"I dunno, Lyra...this is kinda...strange..." Bon Bon's cheeks flushed a little darker from the new sensations coursing through her body; the light tingles of pleasure from her chest, along with the feel of Lyra's smooth fingers sliding over her new body, as well as another strange tingling that seemed to course through her whole body.

"Yeah, but a good kind of strange, right?" the unicorn smiled and nuzzled at Bon Bon's snout again, pulling her a little closer in their cuddling with her hands resting on the other mare's rump, lightly squeezing it which caused Bon Bon to moan softly.

"Mmnh...I suppose, yes..." Bon Bon lightly nuzzled Lyra in return, sliding her own hands around the unicorn's waist and to her lower back, cuddling back against her. As she glanced to the side a bit, she blinked a couple times, now seeing the top of the bookshelf beside her. "Lyra, are we...?" she turned her head further to the side and gasped softly, able to clearly see over the tops of the bookshelves. "When did the library get so small?"

Lyra raised an eyebrow as well, glancing to the other side and seeing over the tops of the bookshelves as well, before grinning a bit. "Heh, I guess the growth portion of the spell works faster than I thought!" she giggled softly, turning back to Bon Bon again. "Not only do we get these awesome bodies...but we get to have some fun as giants as well!"

Bon Bon gulped softly, a bit overwhelmed at the whole situation, still growing steadily along with Lyra as she cuddled up with the unicorn. "I know you said you wanted to do something similar to that shrinking potion we used a while ago...but I didn't know you meant something like this!"

"C'mon, Bons! These bodies are a lot more fun than they appear." Lyra giggled softly, lightly squeezing the other mare's rump and cuddling her a bit tighter, though she grunted softly as her head bumped into the ceiling; her height reaching 20 feet already. "Being big will only make it even more fun!"

"Oh, Lyra..." Bon Bon sighed and leaned in against the unicorn, smiling up at her while her hands stroked over her waist. "How did I ever get stuck with you?" she poked her tongue out playfully, slurping the end of Lyra's snout.

"I sometimes ask myself the same thing!" Lyra smirked a bit and nuzzled back against Bon Bon's slurping, gently pressing her lips to the other mare's while her hands stroked over Bon Bon's waist and rump, both of them starting to press against the ceiling now as they grew and grew; the magic still going strong within both of them.

With another pleased sigh, Bon Bon pressed her lips back against Lyra's, her eyes closing as she kissed her marefriend; her body relaxing as she enjoyed the various tingles of pleasure around her body. It wasn't until her head bumped against the ceiling that her eyes opened again, seeing just how much she and Lyra had grown in the past couple of minutes.

Before she could pull away from the kiss to say something though, her eyes fluttered as she felt faint for a moment; both her and Lyra’s growth surging for a brief moment, causing them to break right through the roof of the library as their sizes continued to swell. Both of the anthro-mares grew and grew until they were at least fifty feet tall, towering over all of the nearby buildings.

Realizing her new height, Lyra finally pulled back from the lip-lock with her lover, grinning wide. "Wow! Look at us, Bons! We're huge!" she giggled softly, glancing over the buildings of Canterlot, while lifting one of her legs up and carefully placing it down in the street beside the library. "C'mon, I wanna see how this thing handles!" she grinned towards Bon Bon for a moment, before lifting her other leg and starting to slowly and carefully walk down the street, seeing lots of ponies fleeing the streets before her.

"Lyra, wait! Be careful, you might hurt somepony!" Bon Bon gasped softly, hearing shrieks and cries coming from below as she tried to follow the other giant mare, though with no experience walking upright, she ended up being the more dangerous one. As she stepped forward, she gasped and began to fall over, scrambling to move her legs in front of her to stay upright. "Waagh, Lyrahelpme!" she shouted, before groaning out loudly as her left foot smacked against a rather sturdy building, stubbing her toe quite painfully on it.

Lyra had barely registered what had just happened before her eyes widened, seeing Bon Bon topple over towards the side of the mountain, just barely missing one of the castle's towers before collapsing against the mountain with a grunt. "Bons! 'You alright?" she bit her lip gently as she carefully navigated the streets, making her way over towards the fallen Bon Bon, who was now holding her foot and groaning in pain.

"Owww, it hurts...!" Bon Bon groaned, her eyes closed as she leaned back against the side of the mountain, still holding her foot firmly with both hands, her big toe reddened a bit from being bumped so firmly against the stone building.

The sight of her marefriend in such a situation caused Lyra to grin though; an imaginary lightbulb popping up over her head. "Heh...don't worry, Bon Bon, I'll make it all better!" she then knelt down at Bon Bon's feet and moved her hands out of the way, before grasping the injured foot's ankle, pulling it up a bit. With the soft foot in front of her face now, she blushed a bit, grinning wide. "It's...beautiful!" she sighed and leaned in, beginning to nuzzle at Bon Bon's soft soles as well as her toes.

"Lyra...?" Bon Bon raised an eyebrow as her eyes finally opened again, feeling a soft nuzzling at her foot, quickly followed by her other foot being rubbed by smooth fingers, stroked up and down repeatedly. "What are you doing, Lyra?" she softly blushed, wiggling her toes a bit from the strange sensation Lyra was causing in her feet; somewhat ticklish, but also strangely pleasing.

"Mm...they're so smooth...I didn't think they'd feel so nice!" Lyra grinned wide as she kept nuzzling at the other mare's wriggling feet, slipping her tongue out and giving Bon Bon's foot a soft slurp, from the heel all the way up to her toes, causing her to giggle a bit from the ticklish feeling.

"Nnh, Lyra...cut it out!" Bon Bon managed to speak through her giggling, smiling down at the unicorn as she kept wiggling her toes against the nuzzles and slurps they were receiving, quickly forgetting about the pain in her toe from all of the other sensations Lyra was providing. "That...hah...tickles!"

With a bit of chuckling herself, Lyra continued to slurp and nuzzle at the wiggling feet a little longer, before gently kissing Bon Bon's big toe and pulling herself up, cuddling with the Earth mare against the side of the mountain. "Heh...sorry, just got a little carried away...made you feel better though, didn't it?" she grinned playfully, feeling her soft chest squish up against Bon Bon's in their close embrace.

"Mmnh, I suppose..." Bon Bon nodded softly, a cute blush crossing her cheeks again as she felt her breasts pressing up against Lyra's. "This body is kinda weird, though...can we just change back now, Lyra? I don't want anyone or anything else getting hurt."

"What? Already? No way, Bons!" Lyra's playful grin curled into a smirk as she brought her hands up, squeezing Bon Bon's chest firmly, which made her gasp softly. "I wanna show you how much fun these bodies can be!"

"If you, ahh, insist." Bon Bon moaned as Lyra's hands lightly squeezed and fondled her sizable breasts, the feeling of the smooth fingers running over the soft mounds providing much more pleasure for her than the rubbing her feet had received. "Go ahead then, Lyra...you've got five minutes to convince me."

Still smirking playfully, Lyra chuckled, nodding her head softly. "More than enough time, Bon Bon." she then leaned her head down towards the Earth mare's chest, continuing to lightly grope them as her snout approached the left mound. Her tongue then slipped out and began to slurp over the nipple, flicking over it as well, sending soft jolts of pleasure through Bon Bon's breasts.

Bon Bon closed her eyes and sighed softly, her blush deepening a bit from the foreign pleasure. "Mmnh...that feels...kinda nice, I guess..." she quietly moaned, her own hands slowly wandering Lyra's back as she felt the little nub on her breast start to perk up and harden from being slurped repeatedly, becoming much more sensitive as well.

"Heh...I've barely started, Bons." Lyra giggled, giving Bon Bon's chest another firm squeeze before pursing her lips around the perky nipple, starting to lightly nibble and suckle on it; her ears perking up a bit as she heard Bon Bon gasp a few times between her soft moans. With her other hand, she continued to fondle and grope at the mare's other breast, thumbing over its nipple as well, eager to give her lover as much pleasure as possible.

"Ahh...Lyra...!" Bon Bon gasped and winced softly from the larger tingles of pleasure in her chest, her other nipple quickly perking up against Lyra's thumb as it was rubbed so much. "That does feel...ah, really nice!" she leaned back a bit more against the mountainside, feeling a familiar moisture between her legs already as her arousal quickly grew.

With a smirk, Lyra kept nibbling and sucking on the nipple, pulling her head back a bit as well, tugging gently on the sensitive nub to further tease her lover with pleasure. After a few more suckles though, she pulled her head back and grinned up at Bon Bon, returning her hand to the breast and lightly kneading both of them again, thumbing over both nipples. "Heh...they should feel pretty good, Bon Bon. But that's only the beginning!"

After squeezing Bon Bon's soft melons one last time, Lyra's right hand moved down the other mare's body and slipped right between her legs, feeling the heat of the aroused marehood against her hand as she lightly rubbed over it. "Let me show you how good fingers can really feel." she winked to Bon Bon, before she gently pinched the earth mare's clit between her index finger and her thumb, rolling it between the two fingers and gently pinching it as well.

"Ah-!" Bon Bon gasped sharply and flinched from the shocks of pleasure caused by her lover's teasing, her cheeks flushing a deeper shade of red. "Oh, m-my, Lyra...!" she stammered before groaning blissfully, feeling her sensitive love nub being pinched again.

"Heh, told ya!" Lyra chuckled, still smirking playfully as she teased her lover's clit, gently tugging at it as her fingers rolled over it. "I don't want to make you cum too fast though, so how about this?" her fingers then let go of the Earth mare's clit, before her index and middle finger pushed past the warm nether lips and slid inside, rubbing against the moist inner walls. "How's that feel, Bons?"

"Ooh...certainly feels...different, at least." Bon Bon sighed happily as she felt the two fingers rubbing inside her, writhing a bit underneath Lyra. As the two fingers rubbed back and forth over her insides, she felt Lyra's thumb return to her clit, sending another surge of pleasure through her body. "Nngh! Is this what she was trying to get at, with her constant raving about those...'humans' ?"

"Hope you're ready, Bons, because here comes the real pleasure!" Lyra teased as she kept pressing her thumb against Bon Bon's love button and rubbing it firmly, while her fingers began to push in and out of the moist slit at a faster pace, sliding along the silky walls within. At the same time, she leaned her snout down and latched onto Bon Bon's left nipple again, starting to suckle on it once more, teasing three of the mare's sensitive spots at once.

With a sharp gasp, Bon Bon arched her back and moaned out loudly, the triple-whammy of pleasure almost making her feel light-headed for a brief moment. "Ahh...oh YES!" she cried, squirming some more beneath Lyra's body, absolutely loving the feeling of the smooth digits sliding in and out of her sex, only causing more of her love juices to flow, slicking up Lyra's fingers even further.

Lyra smirked a bit as she kept up her suckling, mashing her thumb a little harder against the other mare's clit. "Heh...success!" she chuckled a bit in her mind, glad to know that Bon Bon was starting to really enjoy her new body. As she stretched her legs to get a little more comfortable though, one of her feet bumped against a tower, lightly cracking and tipping it, but also giving the unicorn a lovely idea.

While she kept up her fingering and sucking, her horn began to glow once more, enveloping the cracked tower with her magic aura and breaking it off, bringing it closer to Bon Bon's sex. As it closed in though, it moved lower, before prodding against the mare's rear entrance, teasing the tight pucker for just a moment and then gently pushing inside.

"Mmnh...?!" Bon Bon's eyes opened wide as she felt the phallic object pushing into her rear, before she cried out again, though the bit of pain only seemed to intensify her pleasure even further, her soft walls lightly clenching around Lyra's fingers as they kept sliding back and forth inside her. "Ohh, L-Lyra, what are you doing down there?"

Lyra pulled her lips from Bon Bon's nipple for a second to smirk up at her, giving her soft chest a playful squeeze while working her fingers more, pushing them more firmly in and out of her lover's snatch. "Just a little more fun for your new body!” she poked her tongue out for a moment before leaning down again and slurping over the mare’s perky nipple, still squeezing and fondling the other soft breast with her free hand.

With all of the pleasure Lyra was giving her, Bon Bon could only arch her back softly again and groan blissfully, her eyes shut tightly as she already felt her orgasm building up within her, rapidly approaching from the overload of pleasure she was receiving. As Lyra's fingers continued to rapidly thrust in and out of her sopping wet sex, the tower slowly and steadily pushed deeper inside her rear, adding more decadent shocks of pain to her pleasure.

If it weren't for Bon Bon's constant panting and moaning though, Lyra would have been able to hear a slight rumbling coming from behind them, another figure slowly rising up behind them, seeming to grow in size just as rapidly as Lyra and Bon Bon had.

"Mmnh, c'mon Bons...cum for me!" Lyra grinned eagerly as she kept suckling on Bon Bon's nipple, pulling at it and lightly nibbling it, while pinching the other breast's nipple between two fingers, pulling lightly at it as well. She could feel her fingers becoming more and more soaked with marejuices as they kept firmly rubbing along those silky walls, still pressing her thumb over the sensitive nub above as well, each teasing bump bringing Bon Bon even closer to climax.

"Nnh! Oh, Celestia...!" Bon Bon cried out one last time before leaning her head back further against the mountain, feeling the powerful orgasm start to rock her body. Her soft insides immediately clenched around Lyra's fingers, followed by a torrent of her sweet juices gushing forth, splashing all over the unicorn's hand and also onto the buildings below, soaking them with a coating of the hot fluids.

Lyra sighed happily, nuzzling against Bon Bon's soft breast as she felt the hot juices gushing onto her hand, slowly pulling her fingers out of the soaking wet slit and grinning up towards her lover. "Heh...I take it you enjoyed yourself, Bon Bon?" she teased, though upon seeing Bon Bon's shocked expression, she raised an eyebrow. "Is...that a yes?" the unicorn looked confused for a moment before turning her head to the side and gasping softly, her cheeks immediately flushing just as red as Bon Bon's.

Standing behind them was none other than Princess Celestia herself, having taken on an anthropomorphic form just like the two lesbian lovers, albeit somewhat larger, in both size and endowments. "You called?" she asked with a stern look, crossing her arms over her enormous chest; the two white melons at least double the size of Lyra and Bon Bon's.

"P-Princess!" Lyra stuttered, shivering a bit as she cuddled up closer to Bon Bon as if by instinct, giggling nervously. "This, uh...this totally isn't what it looks like, Princess! We were trying to...um...I mean, we were just, uh..."

"Having sexy giantess fun without your Princess, that's what you were doing." Celestia interrupted, putting her hands on her hips now. "You should know better than that, Lyra. How could you grow deliciously huge and not invite me to tag along? I've been waiting for years for somepony to finally find that musty old book and use that spell!"

“I...what?” Lyra blinked a couple times as she stared up at the giant princess, looking even more bewildered now. “Since when...huh? I didn’t know-”

“Oh, hush. You should keep yourself up to date with Equestrian law, dear.” Celestia giggled, before she approached the two mares, her stern look quickly shifting to a smirk. “Now, my little ponies, prepare for some REAL fun!” she then held her hands up, her horn glowing and procuring a rather large equine dildo in both of her hands.

THE END, I suppose.
