Finding your Wings

Spike leaned in and kissed Scootaloo's neck. He embraced her as a lover, right there on the bean chair.

For her part, Scootaloo was all for it, moaning softly as her claw and hoof moved down his body. "I love you, Spike," she gasped. "You're so good to me... I want to repay you."

"You don't have to. I don't want to force you."

"But I want to!" Scootaloo insisted. Gripping his buttocks, she pulled him in close and rubbed her slit against his length. She was already dripping. "Take me, Spike. I'm yours."

Locking lips with her again, Spike pushed until his tip parted her lips. He waited there for a moment, and hearing no complaint, pushed in a bit further.

Scootaloo squeaked out a bit, causing him to stop, but she held onto him to make sure he didn't pull away. "Keep going," she begged.

Spike was nothing if not helpful, and that included being mostly obedient. He continued to enter slowly until he was all the way in. He held there for a moment to let her grow used to the feeling, but he could feel her changing.

At first, Scootaloo's vagina was the same as everypony else's; a vertical slit with a nub at the front end hidden under a hood. But Spike could feel his shaft being twisted as she gripped him. The whole thing twisted anti-clockwise until it was flat, with Scootaloo clamping her jaw shut as it turned. Her back legs held him in place as it twisted around him, neither letting him follow the twist, nor pull out.

When it all stopped, she released her grip, panting. Her pussy was now a horizontal slit, almost matching Spikes, save for the lack of a penis.

Spike pulled most of the way out, his small spines dragging and scraping against her soft flesh as he did. He didn't go all the way out, just far enough that his shaft was no longer twisted. As soon as he was straight again, he plunged back in.

"Ah! Yes! Spike, yes!" moaned Scootaloo, throwing her head back as he began to thrust.

Spike leaned in and pressed his mouth to hers. "It's still a library," he whispered, placing a claw against her lips.

Instinct was beginning to take over for Scootaloo. Her forked tongue shot out of her mouth, grabbed his claw, and brought it between her lips. She sucked on it lightly, using her tongue to jerk it off. It was just a claw, but feeling what she did to it filled Spike's mind with lewd thoughts and redoubled his drive.

He began to thrust rhythmically, slowly at first to match the speed of her sucking, but as she increased the movement of her tongue, he sped up his hips. Soon, it wasn't their voices that resounded through the library, but the wet slapping of their hips. Spike couldn't shush that, nor could he be too upset about it, as this was primarily his fault, as he was the one moving. Sure, Scootaloo was responsible for most of the fluids, but he was making the slapping sounds, and he did not want to stop.

He did kiss her again, though. With their long, forked tongues, they held each others' mouths together, muffling their moans as they breathed back and forth. Their breath was so hot that little flecks of fire shot out of their noses. Spike knew that there was a fire protection spell on the books in here, as he'd sneezed while reading something dusty too many times, and Scootaloo was too lost in pleasure to care.

More things began to change about Scootaloo. Her fur was soon replaced with scales, purple spines began to grow out of her back, and her belly was now covered in plates. They were hard, but flexible. Next to disappear were her hooves, starting with the remaining front, turning into a claw that clung tightly to Spike's arse. Then her back hooves, though it was hard to tell at first because her toes were curled up tight.

Things were a bit finnicky when it came to her tail, though. The tails of ponies and the tails of dragons were not at all similar. While ponies' tails were short with little articulation and long hair, cut short in Scootaloo's case, dragons' tails were muscular, with hard scales sliding against each other and a firm, hefty tip. The transition was slow and exhausting, but Spike's cock was a welcome distraction from the pain, and his warm, loving embrace made it easy to forget that she was being changed. She just felt right when she was in his arms.

"Scootaloo..." Spike gasped. "I can't... I can't last..."

"I don't care," huffed Scootaloo. "You've already made me the happiest filly in Ponyville!"

Spike wasn't kidding. A few moments after he spoke, he pushed his hips all the way forward, and a torrent of dragon seed flooded out of his cock, right into her waiting womb. Even that began to change, as his semen permeated her walls, rewriting her physical form.

Their jaws were locked together, their sharp teeth holding onto each other as more and more sperm shot from his tip. Finally, the two collapsed, with Spike on top and Scootaloo beneath. Excess seed dripped from their union down onto the bean chair.

"I have no idea how to clean that up," sighed Spike. "I'm going to have to look that up..."

"Can't you just throw it in the wash?" asked Scootaloo, her eyes glazing over. "I think that's how most ponies handle it."

Spike grimaced. "I want to make sure it doesn't stain, though. Perhaps I should put it in hot water right away..."

As he began to stand up, Scootaloo grabbed him by the wrist. "Please, wait." The look in her eyes was one of worry. "I... I don't want... to be left alone, here."

Spike leaned down and kissed her forehead. "This is the Castle of Friendship. This is one of the most secure places in all of Equestria. You're perfectly safe, here."

Scootaloo didn't budge. "I'll replace the chair if it can't be saved. I'll learn how to fix it myself, if I have to. I'll have Rarity help me to make sure it's not junk. Just please... Stay with me?"

Spike took a deep breath. Scootaloo had never been a dragon, before. She was at her most vulnerable right this very minute. The Castle of Friendship itself seemed to push through him, informing him of the right decision.

"The chair can be replaced," he breathed. "You can't be."

As if in response, a blanket floated over and covered the two of them. Taking the hint, the two settled in for a much-needed nap.
