Author's Note

As always, spoilered paragraph contains the optional kinks.

Also a note: I'm gonna take a couple days' break from uploading. I have the rest of the story outlined, but the details have been changing enough as I commit them to paper that I want to think over the course of the story and where I want it to go. The ending is going to be the same, but it'll be how we get to that point that I'm mulling over.

Memento

Rainbow Dash sighed as she reclined against Gilda in their shared bed. It had been 24 hours since she had returned to the temple, and the changes were beginning to accelerate. Now completely bare save for the Element hanging from her neck, there was no hiding the way her body was growing.

Her six pack had grown into an eight pack like Gilda’s, and her arms and legs were packing on enough muscle to put most female bodybuilders to shame. If Gilda’s build was anything to go by, Rainbow Dash would be putting male bodybuilders to shame soon enough.

No wonder the pegasus had such a voracious appetite the past few days! She couldn’t stop apologizing for emptying out the griffon’s reserves of fruits and vegetables, but Gilda insisted it was alright. Then she would try to get Dash onto eating meat like her, which Dash flatly refused each time. She’d already possibly screwed herself out of the Wonderbolts bulking up like this, she wasn’t about to screw herself out of being a pony altogether.

Looking down, the swell of her rapidly expanding breasts took up her view. She was easily past an F-cup now, though she couldn’t be sure. Her dark blue nipples were longer and thicker, and her areolas wider. Not quite at Gilda’s level just yet, though she’d noticed that she was catching up to the griffon in height.

Though she couldn’t see it, she could feel her snatch aching with constant need. Like Gilda, she was wet all the time now, which made resisting the griffon’s advances next to impossible. In fact, they were just coming down from yet another mid-morning romp.

Rainbow Dash probed her mound with a finger and inhaled sharply. Her folds were definitely meatier, and she couldn’t remember the last time her clitoris hadn’t been erect. It had to be jutting out almost a full inch, and was definitely plumper. The pegasus quickly withdrew her hand before she got herself all worked up and she and Gilda ended up fucking yet again.

As she withdrew her hand, her fingertips passed through her pubes. Unlike her mane and tail, her other body hair was a uniform red. When she had come to the island, they’d been trimmed into a neat triangle over her sex. Now, however, they were growing out into a curly, dense bush. Yet another thing making her like Gilda. Similar crimson crops were sprouting under her arms, and it was working wonders to trap in and amplify her rank scent. Dash suspected that the island was making it all grow in a lot faster than it would otherwise.

Rainbow Dash frowned. All of this was the last thing she’d wanted when she set out to get Gilda. While the temptations and whispers of the Spirit had been easy enough to ignore, her mind always grew hazy if she dwelled too much on the life she was away from, especially Applejack.

Would she ever make it home? It had only occurred to her the past couple of days that she hadn’t really had an exit strategy. She figured if Gilda refused, she could go get her friends and try again. She hadn’t anticipated the Spirit intervening directly. Now here she was, rapidly changing into something she wasn’t supposed to be and slim chances of getting off the island herself.

No, she had to try something. Anything. Perhaps the griffon she knew and loved was still in there somewhere? The pegasus resolved to jog her memory.

“Gilda?” she quietly asked, stirring the griffon from her post-coital catnap.

“Hm?” she replied sleepily.

“Just how much do you remember about life before the island? I mean, you gotta remember something. You knew who I was, for example.”

Gilda heaved herself up, her usually serene face scrunched up in concentration. “I vaguely recall that I visited your town. We had a fight, and I left believing our friendship was over. Words cannot describe how happy I am that was not the case!”

Her hands reached out to stroke down Rainbow Dash’s sides. The pegasus hummed in appreciation and leaned back into the griffon. Inside, she was disturbed at how readily she was accepting Gilda’s affections. The Spirit might not have rewritten her personality, but it was attacking her inhibitions. At least, that’s what she told herself.

“Anything else?” Rainbow Dash prodded, holding fast in her resolve not to let this become just more sexy time (yet, at least).

“It is hard to describe,” Gilda continued. “I have no recollection of most events before I came to the island. After I sent the journal away, the only written account of my past before serving the Spirit went with it. Places, people, all of it is gone. However, you and your friends stayed.”

She pondered for a few more moments. In the process, she leaned forward and pulled Rainbow Dash on top of her. Despite the pegasus’s rapid development, the griffon was still bigger and stronger.

Rainbow Dash yelped as she came to rest on Gilda’s broad chest. A fierce blush flooded her cheeks, and the heat in her loins intensified as her expanded rack squished softly into Gilda’s breasts, only to be enveloped in their superior volume. The warmth of the griffon’s ever-present milk was oddly soothing, especially as it ran down Rainbow Dash’s boobs and down her abs.

“The best that I can describe what little memory I have is in feelings,” Gilda finally said. She was purring now, and rubbing Rainbow Dash up against her. “I remember you, and I remember that we were close friends for many years. I also remember how much I looked up to you, and the jealousy I felt that you had other friends. As for the events that prompted those feelings, I have no recollection.”

Rainbow Dash’s eyes were screwed shut. She wanted nothing more than to lift one of Gilda’s legs and grind their cunts together with wild abandon. But she needed to keep the griffon talking. Something had to be in there. “Do you remember Junior Speedsters?” she managed to get out.

“What was Junior Speedsters?” asked Gilda. Her talons were now pricking into the chiseled muscles of Rainbow Dash’s back, making the pegasus shiver in delight. Dash could feel how they extended and retracted with practiced ease. No doubt Gilda could shred right through her if she ever wanted to. Best to stay on her good side, then.

“It was - nnnnhh~ - flight camp for young pegasi and other flying creatures. You were the only griffon. Hffff, you were so alone and afraid. I - hah~ - knew you had potential, and just needed some encouragement.” Rainbow Dash grit her teeth. The way her tits were grinding into Gilda’s - getting all hot and slick and slathered in all that milk - was running the risk of making her cum hands-free.

Gilda rumbled in pleasure. The stench of her arousal was easily drowning out all other scents in the room. Still, she maintained her composure. “So that is how we met, is it? I do recall something.”

The pegasus stiffened. Had she found a way in? Perhaps gotten through to her?

“Let me show it to you.”

Rainbow Dash was crestfallen that it pertained to something she had with her. At least she got the reprieve of Gilda rolling out of bed and away from her. That allowed her overwhelming lust to subside somewhat. But it was only short lived, for a minute later, Gilda effortlessly hoisted her up to get back in bed, then placed Dash right where she had been.

The pegasus was now straddling Gilda’s washboard of a belly. Dash resisted the urge to press their breasts together again, and opted to prop herself up with her hands against the stone wall at the head of the bed.

Meanwhile, Gilda produced the object she had fetched. “I brought this to the island with me. Though it no longer functions, and I do not know precisely what it is, I do know you gave it to me.”

Rainbow Dash timidly took one hand off the all to take the battered and worn accessory. It was a digital wristwatch, bright blue with yellow lightning bolts on the band. The long dead and corrupted LCD face was flanked on either side by Captain Spitfire and Soarin. Just from a glance, Dash immediately knew its significance.

“This...you...the Wonderbolts watch I gave you for your birthday,” she breathed. Even though she knew nothing would happen, she pressed the buttons with her thumb just to be sure. “I figured you’d have thrown this out long ago!” Her chest tightened and tears welled in her eyes as it sank in. Even after their fight, even after Gilda had renounced her past life, she had still held on to this last artifact of their friendship. What Dash didn’t know is that mention of the watch had been removed from the journal before she had the chance to read it.

Gilda cocked her head in mild concern. Why was Rainbow Dash sad? “That’s right,” the griffon cooed, “I knew that we would be reunited one day. And here you are!” Her hands ran up and down the pegasus’s impressive, milk-soaked abs. That broke Rainbow Dash out of her storm of emotion and coaxed a pleasured moan out of her. Perhaps another round of sex would cheer her up?

Rainbow Dash dropped the watch and planted both hands on the wall once more. Her heavy breasts hung down over Gilda’s face. From this angle, she could feel the way her pulse throbbed within them. It was like she could feel them growing in real time!

“Y-yeah, I’m here now,” Rainbow Dash said with a sniff. The fires of arousal were stoked ever higher by the sentimental feelings that’d overcome her moments before. Her hips bucked involuntarily, causing her snatch to grind up Gilda’s abs. Holy fuck that felt good! Given the pleasured groan the griffon made, she must have enjoyed it too.

Before Rainbow Dash could have second thoughts, she was caught off-guard by Gilda latching her beak onto one of her nipples. For such a rigid body part, the griffon was able to use it with care. Her thin tongue lapped at the fleshy nub now trapped in her maw, and she suckled as best she could given her anatomy.

Rainbow Dash’s fingers and toes clenched. Her unkempt nails dug into and scraped lines down the stone bricks. Her hips rolled in a steady rhythm now as her pussy was dragged up and down Gilda’s solid belly. The blush had taken over most of Dash’s face, and she panted needily.

There, the pegasus was in better spirits already! And she would need to be if she were to serve the Spirit. Gilda smiled as she kept working on Rainbow Dash’s nipple. Her hand came up to gently squeeze and massage the unoccupied breast. The other hand rested on the small of her back to feel those rapidly developing muscles and the way they flexed and bulged with her movements. Dash responded by picking up the pace. Soon Gilda’s abs were just as coated in the pegasus’ arousal as hers were in Gilda’s milk.

With Rainbow Dash properly warmed up, there was no chance of her lasting long. “Ahhhh, fffffuck Gilda, I - AH!” her whole body tensed as she dumped a generous gout of girlcum onto Gilda’s body. There was enough to trickle down between her abs to her mound, where it matted her abundant pubic fur.

Gilda released Dash’s nipple from her beak to grin hungrily up at her. “Do not think you can take another nap so soon, my dear,” she growled, “For I am only just getting started. Let me show you how real animals like me make love!”

With that, Gilda grabbed Rainbow Dash and rolled over in the bed to pin the pegasus. Her hot breath washed over the mare’s face as she rumbled and purred. Her olympian muscles flexed over the pegasus in full view. Veins stood out prominently on her arms and legs.

In this position, Rainbow Dash simply could not resist. “H-heh, s-sure Gilda!” she said with eagerness, a little bit of fear, and a hazy, lingering sense of remorse at what she was doing. “Show me what you goo-ahh-hahh.” Dash never had the chance to finish as Gilda’s beak pressed into her tender neck and the griffon’s knee pressed into her hypersensitive snatch.

It would be another two hours and almost ten orgasms between the two of them combined before they emerged from the temple outbuilding to start the day. Before Rainbow Dash could take her leave, Gilda stopped her and turned her around. The griffon then planted a soft kiss on the pegasus' lips.

"I will be out gathering," she said to Dash, "Perhaps later I can show you how to make tools, so you can come with me."

Rainbow Dash, her mind clearing in the afterglow, said "Aheh, if you want, sure!" Her heart wasn't in it, however.

Gilda planted one final kiss on Dash's cheek, before gathering up her leather satchel and leaving out the temple's front gate. Rainbow Dash sat down at the base of the palm tree in the center of the court yard and buried her face into her drawn-up knees.

"Dammit!" she groaned, tears prickling at her eyes once more, "Why can't I stop doing this? AJ, I'm sorry. I'm so fucking sorry."
