Sora and Kairi had found their way back to one another. After the battle with Xehanort and his Seekers of Darkness, they had won. After losing both their hearts to the unknown, they had found each other.

Finally, after years of fighting to find the other once more, they could finally be together. The Darkness was behind them, and now they were free to finally be together.

“Ahh… I’ve missed this place,” Sora sighed, falling back onto the soft sand of Destiny Island. “It feels like years since I was last here!”

“It has been,” Kairi reminded. “We were kids last time we really got to enjoy ourselves out here,” Kairi commented, letting her feet sink into the sand, watching the waves crashing nearby.

Sora nodded his head, a thin frown on his lips. The two of them were adults. Far from their time as kids, far from when they both began their journey. “I missed a lot of homework.”

“You’re lucky ‘had to save all of reality’ was an acceptable excuse,” Kairi teased, and Sora laughed.

“Donald was a rough enough teacher. He made sure I kept up with my studies. We had a whole classroom set up on the Gummi ship.”

“Studying English with him must have been fun.”

“‘Sora, no, pay attention!’” Sora declared, trying to imitate Donald’s characteristic lisp. ‘“What’s two plus two!?’” He wagged his finger, continuing to imitate the wizard as Kairi laughed. “Don’t worry. I paid attention. It’s six.”

Kairi gently pushed Sora’s shoulder as she continued to laugh. He laughed with her, only to gasp as she wrapped her arms around him, squeezing him in a tight hug. “I really missed you, you big doofus,” she muttered.

“I missed you too,” he whispered, wrapping his arms around her.

She held him a little tighter, gently kissing his neck. “I really… really missed you.”

“And I you.” His hands gently slid up and down her back, nuzzling against her. “Kairi?”

“Yeah?”

“I love you.”

How long had she wanted to hear those words…? She had wanted to spend her life with Sora since she was young. Friends forever, but as she grew older, she began to realize it wasn’t just friendship that she wanted.

She wanted him. In mind, body, and heart. She wanted to spend her life with him as more than just a friend. She wanted love, and to love in return, and finally, after years of the fates keeping them apart, she was free to be with him.

“I love you too,” she whispered, and she kissed his lips.

Sora froze for a moment. He had never kissed anyone before, but he had waited for this moment for so long. He had saved himself for her, even. Princesses of faraway kingdoms confessed their feelings for him, but he held firm.

He didn’t want anyone else, but Kairi. He wanted to love her till the end of his days, and finally, after so long, he had his chance to do just that.

He held her tight, kissing back. Her lips were so soft, and then felt her tongue gently pressing against his lips. He parted his lips, accepting the tongue and moaning quietly as it explored his mouth. One of his hands slid down, gently rubbing against Kairi’s butt as he was reminded of how much she had changed.

They weren’t kids anymore. They were adults, and as embarrassing as it was, Sora had been filled in regarding the birds and the bees.

He had no intention of forcing things to go further than Kairi wanted, but he was more than happy to move alongside her. If she wanted this, he’d give it to her. If she didn’t, he’d wait for as long as she wanted.

The two stood on the beach together, quietly making out as the sun set in the distance. Neither paid any attention to it, though. The love they shared burned far hotter, and more brilliantly, than any star.

Truly their love was a beautiful thing, but the light of it proved to be blinding as a pair of golden eyes stared at them from the shadows of a palm tree. It stared at the two Keyblade Bearers, slowly swaying side to side.

It did not stare in anger for its fallen kin, nor did it stare in hunger of their hearts. It stood there, wanting only to stare at the light that was their love. It had never seen such brilliant radiance, and it wanted to be a part of it.

Somehow.

It stepped forward, moving a tendril out of the shadows as it slowly began to inch forward, moving silently over the sand as Sora and Kairi remained locked in the other’s embrace. They were happy to just melt in the other’s arms, and this sealed their fates as the Heartless began to dash towards them.

Sora opened his eyes, having only wanted to stare at Kairi’s face as they kissed, but his eyes widened as he saw it. A Heartless, one that resembled some kind of squid or octopus, was running at them on several long, tentacle-like legs.

The brunette pushed Kairi back as he formed his Keyblade. He took a swing at it, believing he was the creature’s target, but it leapt over him entirely. Sora’s gaze followed it, before he tried desperately to stop it. It fell onto Kairi, and immediately it seemed to melt.

“Sora!”

“Kairi!”

He ran to her side, trying to pull the Heartless off of her, but it had already seemed to melt into her skin, flowing over her arms like it was a living tattoo. The black mass rose up to slide over her clothing as Sora’s eyes widened in fear.

“Kairi!”

He watched as the darkness crawled up Kairi’s mouth. Her blue eyes stared at him, too afraid to even say anything as darkness slid down her throat. She coughed, clutching her throat, hoping to spit it, only for her eyes to vanish under smooth, black skin.

She laid motionless on the floor, unmoving as Sora stared at her. She almost looked like a mannequin. Smooth skin, her clothes having seemed to vanish under the darkness. He wasn’t sure what he could do, but he clung to his keyblade.

Maybe there was a spell he could use? Maybe-

“Sora?”

A voice. Kairi’s voice. But how? She didn’t even have a mouth anymore. Sora just stared as the black figure slowly rose up. The darkness seemed to blink, before a pair of bright blue eyes stared at him with clear confusion.

Big, blue eyes. Like a Heartless’ normal eyes, but… blue. The same shade of blue as-

“Kairi?”

“Sora?” She turned her head to look at him as the darkness seemed to shift slightly. Sora was able to see more detail in the darkness, like purple veins were traveling from the bottom of her feet to her head, and long violet locks flowed down her back, like hair.

Sora was about to speak when his face turned red and he froze in place. Kairi, or this Heartless controlling Kairi, had… breasts. Breasts that were much bigger than before. Large, heaving tits made of darkness, completely bare, with purple nipples standing on top.

He quickly turned his eyes away, trying to catch his breath as Kairi shifted slightly.

“I feel… weird.”

“T-that Heartless attacked you! Are you hurt? A-are you still… you?” he asked, turning his gaze back to her, careful to keep his eyes on hers.

“I think so. I still feel like me. Just… better,” she confessed, watching her fingers slowly move back and forth. “Stronger.” She turned her head towards Sora, and in an instant, she stood before him.

“Whoa!” He jumped back, only for her hands to catch him and bring him close, pressing her chest against his.

“Sora…”

“Huh?”

Sora watched as two small antennas popped out of Kairi’s head. She gave them a wiggle as Sora glanced down, watching Kairi’s body become more hourglass-like. It would have been impossible for any normal human to have a figure like this, but it was quite clear that Kairi was no longer normal.

“I don’t just feel stronger… What I feel is stronger too. Including my love for you, Sora.” She opened her mouth, revealing a row of black, sharp teeth. Drool dripped from them as Sora felt…

Honestly, he felt aroused.

Kairi’s body was shapely, curvaceous, with a voluptuous figure that begged for attention. The teeth did absolutely nothing to dissuade him from admiring her smooth black skin, her bright, blue eyes, or how soft her chest felt pressed against his.

And judging by Kairi’s tone, she noticed just how enamored he was.

“Do you like my new body?” she teased. “Sora, you big goof… If you want it, all you have to do is ask,” she purred, gently nuzzling her cheek against his. Her long tongue slithered out of her mouth, licking his cheek as he felt one of her sharp teeth brush against his cheek.

He gulped, and his cock pressed against Kairi’s thick thigh, earning a moan from his girlfriend. “Oh, Sora… Is that a Keyblade in your pants or are you just excited to see me?” Sora blinked, before he snorted quietly.

Kairi seemed to pout at that, and her face seemed to blush slightly as she stepped away. “O-okay, so maybe that wasn’t so clever.”

“N-no. I-it was good,” he replied, and when he heard Kairi laugh with him, he knew for a fact that she was still her.

Once the two were done laughing, Sora placed a hand on Kairi’s cheek and leaned in close. “Kairi.” She stared back at him as his thumb gently brushed against her skin. She licked her lips, slowly coloring them pink through her own strange powers. He tried his best to ignore how soft they looked as he made his vow. “I promise, I’m going to help you turn back to normal. I swear… but until then…”

“Yes?” she teased, drawing hearts on his chest with her finger.

“I think you look really, really hot… and I’m kind of, uh..” Her other hand rubbed against his hard cock, gently kneading it down his clothes. “Y-yeah.”

“Heheh. My thoughts exactly.”

And with that, Kairi shot her hands out. Her clawed fingers tore right through Sora’s clothes, and they fell to shreds onto the floor as his eyes widened.

“H-hey! Kairi, that was my favorite-oof!” She tackled him down, pinning him under her body as she smiled down at him.

“You’re my favorite,” she replied, dragging her claws against his chest. “And now, I can finally show you just how much I love you, Sora.”

“Whoa…” The way her claws dragged against his skin was… something else. He gulped, feeling her body gently grind against his as she moved her hips, slowly bringing them closer to his hard cock.

Black tendrils slid out of her body, gently stroking Sora’s skin as his eyes widened. He shuddered at the sensation, before he felt her bare, naked pussy rubbing against his cock.

“W-whoa…”

“You like that?” she asked. “Then you are going to love this.” She gently stroked his bare, naked dick with her soft, warm tendrils. The two both moaned at the sensation as the tentacles aimed his cock at her waiting, wet pussy.

She teased herself, rubbing the tip into her again and again, before she sat down. His cock slipped right inside and the two cried out in pleasure at once. Kairi’s hands landed on Sora’s chest as she bounced herself up and down, mewling in pleasure as his cock throbbed inside of her.

“Ahhh! Fuck, it’s so good! I’ve wanted this for so long! Sora!” Her claws dug into his chest, drawing a bit of blood as she moved her hips. “Just s-sit back and relax, Sora! Let me do all the work!” she cooed, bouncing herself up and down as his rod slid in and out of her.

Sora obeyed, moaning in pleasure as her warm, wet pussy squeezed his shaft. His eyes widened as small tendrils moved within her pussy, adding even more pleasure to what he was experiencing. He nearly shouted, arching his back as Kairi matched him.

“Ahhh! S-Sora, you’re so big, and hard, I love it! Oh, you really love this new body for me, don’t you?” she cooed, groping her own large breasts. He stared at them, watching Kairi’s fingers sinking into her rack.

It was so fucking hot, and he could feel his precum coating the inside of Kairi’s cunt. He kept thrusting, fucking her as hard and as fast as he could as Kairi moved her body on top of him.

Were anyone to wander onto the beach, they would find a unique sight. A monstrous woman with bright blue eyes and large, heaving tits riding a young man, bouncing up and down on his cock as she impaled herself over and over again.

“S-Sora, you’re making me lose my mind,” she panted, clawing at his chest, cutting at him. “S-suh, sorry! I’m sorry, I-”

“It’s okay,” he grunted, and he quietly used a quick spell to heal himself. “I can take it.” He grinned as he slipped one of his hands behind her backside, spanking it. “Question, can you?”

Kairi shuddered at the challenge, and she quickly began to move her body even faster. She fucked herself raw on his cock, letting it pump her full of precum, getting her ready to receive his seed. She enjoyed every moment of it, bringing herself to the edge of a climax, but holding back each time.

She wanted to make sure she came at the same time as her lover… Speaking of who, Sora stared at Kairi’s new body, and part of him kind of liked her even more like this. Her new confidence, her raw desire, and now to mention the gorgeous body…

He grabbed her ass, digging his fingers into her plump, soft ass. “Kairi!”

She squealed on top of him, screaming as her entire body began to tremble. She felt his cum flooding her insides as she came with him, riding the waves of the orgasm. The greatest orgasm of her life…

So far, at least.

She moaned with pleasure as she threw her head back, crying out almost like an animal as Sora’s cum coated the inside of her pussy.

The two rode the waves of pleasure, before they eventually came down. They were ready to go again, but Sora and Kairi were also happy to just lay on the bed together. They stared up at the night sky as Kairi dragged her long tongue along his cheek and neck.

“Mmm… So, how’d you like that, stud?” she asked, stretching a tentacle out of her body to gently rub his dick.

“That… was… amazing,” Sora panted, and Kairi giggled as she licked his cheek again.

“My thoughts exactly. Want to go-?”

“Hell yeah!” Sora pulled his lover into another kiss. The two laughed, rolling on the sand as they began to make love all over again.
