The Diaper Spell

Spike sat high on Twilight's back as she trotted up the stairs to Pinkie Pie's room.  When they knocked, the door flew open and the bright party pony smiled. "Hey Twilight! Cool surprise! I'm so super duper glad you came here! But why did you come here?" she yipped. Twilight smiled. "Pinkie, I think you should have a party! It's Cocoa Puff's birthday today!" she said. Pinkie gasped. "Omigosh Twilight, I completely forgot! I better get ready!" she hyped, slamming the door. Twilight smiled and walked home. "Twilight, can we get home real soon? I have to go to the bathroom." Spike blushed. Twilight nodded, but slowered her pace. Just picturing Spike's warm pee running into his diaper and feeling it on her back gave her goosebumps. "Don't forget Spike, if you don't use your diaper all day, I'll take it off for good!" Twilight reminded her purple companion.

He nodded, but was shaking with the effort of holding in his pee. Finally, they arrived at home. "Just let me get my keys." Twilight told Spike, and he nodded. What she was really doing was performing her spell. She felt a wet, hot stream fill the diaper on her back and fill her with warmth. Embarrassed beyond control, Spike pounced off Twilight's back as she unlocked the door and ran inside. "I'm so sorry Twilight!" he sobbed, running off to his room. For the first time, Twilight felt a little guilty. How badly had she actually embarrassed her friend? Was she being mean? But it was so much fun, how could she not?

She trotted up the stairs and saw Spike curled up on his bed. Her horn began to glow and she changed his diaper. He sniffled, and thanked her. Hours passed, and finally, a curious piece of paper came through the mail slot and landed at Twilight's feet. "Party Party PARTY!" it read. "Come to Sugar Cube Corner at 6:00 to celebrate Cococa Puff's birthday!". Twilight smirked with satisfaction. It was going to be a great evening. At 5:55, Twilight trotted up the stairs. "Do you want to come, Spike?" she asked. "Fine, sure." he huffed, climbing onto Twilight's back.

At 6:00, they arrived to see the party had just begun. Spike hopped off, and walked off to enjoy the party. Twilight did the same, trying to locate Pinkie Pie. Finally, she did. Twilight's horn began to glow, and Roseluck, who was dancing, suddenly got a desperate urge to release her bowels. She raced off to the bathroom and locked the door behind her. Twilight smiled, and her horn started to glow again as Pinkie got a signal from her bladder that indeed it was very full. "So Pinkie, what's up?" asked Twilight. Pinkie began to sweat and gnaw at her bottom lip. "Be right back Twilight, I just have to use the little filly's room real quick." she chuckled nervously. Then, she raced off in the opposite direction.

When she got there, she tried opening the door, but it was locked. "Oh no!" she whispered under her breath. "I can't go anywhere but the bathroom, it's against the party pony code!". Tears began to fill her eyes as she approached Twilight again. "Back already? That was fast." the purple unicorn tried to sound surprised. Pinkie's haunches were squeezed tightly together and she was trembling. Spike was standing beside Pinkie, drinking a pepsi. He chugged it back, and Twilight's horn began to glow as Spike's diaper filled and he blushed.

Pinkie began to just up and down. Thinking she was dancing, the ponies began to stare and clap. Suddenly, Pinkie couldn't hold it any more. The pain was too unbearable, and she just couldn't hold it in anymore. Her bladder was too full to contain. The ponies gasped as Pinkie's pee splashed onto the ground.Spike looked at Pinkie and pointed to his diaper, then winked. She sobbed and nodded.

"Twilight, can I have a diaper too? Just for now? I mean, I'm not a filly, but..." she began to cry as she collapsed into her puddle. Twilight began to feel very guilty for what she had done, her friend was crying. Her friend was sad. Twilight nodded in sympathy and strapped a diaper to her friend, changing Spike's, too.

After that, Pinkie Pie was left to clean while the other ponies left, including Spike and Twilight Sparkle. When they got home, Spike sat on the couch and Twilight sat across from him. "Spike?" called Twilight. Spike looked over to her. "I just want you to know...you're still just...you know...a baby dragon...so don't...you know...feel bad, or get embarrassed. Because these things happen to babies. It's just...natural." Twilight comforted. Twilight had decided that she would no longer be using her spell on Spike, he had had enough. Spike blushed and nodded. He wasn't very comfortable talking about this with anybody.

Twilight nodded, and Spike went up to bed. So did Twilight. When Twilight woke up in the early morning, Spike was laying in bed with a wet diaper. Twilight gasped. Spike had wet HIMSELF. AGAIN! She clicked her tongue as she changed him in his sleep. She peered through her telescope and happened to spot Pinkie in her room, sobbing and looking at her diaper. Again with the guilt. Spike rubbed his eyes, and sat up in his fresh diaper.

"Morning spike. Good sleep? I had to change your diaper again this morning, by the way." she smiled. Spike bushed again, and nodded. "It was a great sleept. Sorry about...uhm..." he stammered. Twilight nodded in understanding.
