"No," answered Twilight when she heard Celestia's pleads.

"But Twilight, you know NOTHING about what he's like! He's all... sex-addicted!" said Princess Celestia.

"So?"

"Look, Twilight, he's... he... every 48 hours..."

"Princess, I know enough about humans to know that some, like Devon, are like that. And there's nothing I can do Princess!"

Princess Celestia pondered over it. Then it stuck her like lightning.

"Twilight, maybe you and your friends can do something about Devon," Celestia fluttered her eyelashes, looking at Twilight with innocence.

"No," said Twilight.

"Twilight, as your teacher and mentor, I order you to-"

"Princess, no. I mean, I'm flattered that you chose me, but me? With Devon? This pervert, sex-addicted, jerk?"

"Twilight, ad your mentor, I need you to-"

"Ask somepony else! Princess, I'm a virgin, and-"

Princess Celestia shook her head.

"Then you're no longer my faithful student. You have failed me Twilight Sparkle," she said in a somber tone.

"Wait!" Twilight exclaimed. The princess raised her eyebrows.

"I'll do it!" said Twilight, defeated.

"YESH!" cheered Princess Celestia. "He'll be there in an hour,"

"WHAT!?"

"Devon?" Princess Celestia asked her 'guest'.

"Yeah? I'm kinda busy, you talking mule. And like I had promised myself-"

"Devon, you're going to Ponyville. Now." she said.

Devon looked at her puzzled. "Says who? You? Pft! You're just a gawdawful pony princess," he said, stretching his fingers.

"Devon, you need to. You need to learn about friendship, and my student Twilight Sparkle has offered to do so herself," she said, partially telling the truth.

"Friendship? No,"

"And there's a bonus," she blurted out. This made Devon stand up.

"And what is this bonus you speak of?"

"Twilight Sparkle. She had offered to help you complete your... duty.... task... whatever."

Devon raised his eyebrows.

"Is she hot? Even though she's a pony, is she horny?"

"She's hot and horny. And she needs you Devon,"

"Okay, get me to Ponyville, NOW! My 48 hours are nearly up,"

"Twilight, this is Devon, Devon, this is Twilight," said the princess.

Twilight was a purple mare, with purple eyes and an indigo mane with a vertical pink stripe running through it. On her rump was a magenta star with smaller white stars surrounding it, and on her head was a long, purple, unicorn horn. She was slim and looked tight, and Devon was ready.

"Nice to meet you," said Twilight, smiling.

"Same," said Devon.

"I'll leave you two alone. Luna's waiting," said Princess Celestia, flying off back to her castle, leaving a silent Devon and smiling Twilight together, alone.

"So, Devon. I'm Twilight, Princess Celestia's faithful student. Or so she says. I was here to teach you about friendship," she said, spinning around. Devon followed her to a giant tree (which he found out was really a library). But with each step Twilight took, Devon could only look at her ass (or how they said it, rump), and how it shone in the sunlight, and was already having a vision of his cock in there, pumping into the mare.

Inside the giant tree, Devon got instantly bored. He really, really, didn't want to learn about friendship. His 48 hours were going to be up in ten minutes, and this fine mare was just standing in front of him, like a virgin, and Devon wouldn't be able to keep his hands off her soon.

"Devon, the princess tells me you need to have an orgasm every 48 hours, and if my calculations are correct..." she paused for a second. "... those 48 hours will be up in nine minutes,"

Devon nodded. "But they're no girls in sight, except you," said Devon.

Twilight nodded. "And that's why I'll be happy to help you. Help you have your desired orgasm,"

"Really?" said Devon, searching for the buckle in the belt that held his pants up.

"But." she said. Devon hated buts. Not butts. He adored butts, especially soft, silky ones which belonged to girls. He just hated buts. "If I do, you must permit me to give you one lesson about friendship,"

"No way," said Devon.

"Yes way. Like I said, the clock is ticking," she said, pointing at a clock hanging off the wall. Devon brought his hand to his face.

"FINE!" he screamed. There were only three minutes left, and he wasn't going to fail. And anyways, Twilight was smoking hot.

Devon didn't have any time to waste. He fumbled with his belt

"FINE!" he screamed. There were only three minutes left, and he wasn't going to fail. And anyways, Twilight was smoking hot.

Twilight walked at the window, and closed the curtains.

“You can leave a light on” Devon winked.

“Sure. How else can you masturbate?” Twilight smirked.

“What?” Devon yelled.

Twilight threw a book and a box clinex to Devon. “don’t spill any…. Thing… on the carpet please.”

Devon was stunned by this action. “I thought you…” his pants fell of and revealed his weewee.

“I said I would help you” Twilight turned away. “not that I would have sex with you.” And she ran outside.

“That mule of a…” Devon looked at his watch… “crap! Only two minutes left!” he opened the book and saw the purple unicorn on a picture, together with five other hot ponies… “Hello there…and all nude…”

***

Three minutes later, Devon walked in the kitchen with the unopened box and the book.

“That was fast.” Twilight smirked.

“No wonder.” Devon said. “six hot smoking girls, and nude…” he threw the book on the table. “and a forced arm.”

Twilight wanted to levitate the book.

“I wouldn’t open that for the first… ever….” Devon said.

Twilight closed her eyes and felt some rage coming up. “You didn’t …. In my book”

Devon started to smirk. “I wouldn’t load on your carpet. Which I didn’t…” he smiled.

Twilight opened the book and felt the content of her stomach coming up. “grose.”

“My revenge.” Devon smile. He walked to a drawer and searched for some food. “hay? Twilight… do you have something to eat? I’m kinda hungry.”

Twilight threw the book away, and grabbed Devon with her magic. Sure. But first, you need to learn your lesson”
