The wagon pulled up in front of Canterlot Palace. A guard walked up to the wagon and said, "Who goes there?" The doors in the back of the wagon opened up and out walked little Twilight Sparkle and her parents. "Ah, Twilight Sparkle. You're Celestia's student, right?" asked the guard.

"Twilight Sparkle is curious about a certain topic, and we chose to have her discuss it with the princess." said Night Light, in a rather nervous tone.

"A certain topic, eh?" said the guard. "Like what?"

"Something Twilight has found out recently and is unsure about." said Twilight Velvet.

"Yeah," said Twilight Sparkle, "peeing in-" and then Night Light covered Twilight's mouth with his hoof before she could finish her sentence.

"Please don't say that right now until you see Celestia. Then you can ask her." he said.

"Ok, ok, come on in." said the guard, and he opened the tall doors to the palace. Twilight Sparkle walked in, leaving her parents behind. She still felt a little nervous. What if Celestia did it to her? Nah, they were both the same gender, and that would be totally weird. At the end of the hall sat Celestia on her throne, sipping her tea.

Celestia noticed Twilight walking up to her. "Oh hello there Twilight, my good student. What do you need?" she asked.

"I'm here to ask a certain question" said Twilight.

"Yes, what do you wish to ask?"

Then Twilight said, "I'm here to ask: how does peeing in somepony mean love?" and then Celestia's eyes shrunk, with a surprised look on her face. Then that surprised look opened up into a smile, a naughty, maniacal smile.

"Oh, so you asked THAT question..." said Celestia in a perverted tone. Twilight noticed as Celestia's mane began to turn from bright multicolor to a light shade of lavender.

"What's wrong, Celestia?" Twilight asked, a little creeped out by her behavior.

"Oh, nothing!" said Celestia, her voice, eyes, and mane going back to normal. "Well, I can answer that question. Here come up into my bedroom."

Twilight followed Celestia up a large and wide staircase to another tall door. Celestia opened it and they both walked inside. "Can you take a seat here, please?" said Celestia, pulling up a chair at a desk. Twilight took a set down. Then, Celestia put on her glasses, cleared her throat, and used her magic to make a blackboard appear out of nowhere. "So, let the lesson begin" said Celestia, levitating a piece of chalk.

"What's the lesson?" asked Twilight as Celestia wrote on the board. She wrote: LESSON XXX: HOW PONIES MATE. "Mating? What does mating mean?"

"Well, you're about to find out, my student. Now, look and listen." said Celestia as she erased the chalk and drew a heart. "First, let's talk about love."

"My fillysitter Cadance can use love spells! She's who my brother peed in!" said Twilight.

Then Celestia explained, "Well, you see, when two ponies are in love, and they really love each other, so very much, they show how much they love each other."

"How?"

"Well, you know that hole that you pee out of?"

"Yeah?" said Twilight, looking at and pointing to her vagina.

"Good. Now, have you seen what your brother pees out of?"

"Yes."

"Come up here and draw it on the blackboard."

"Ok!" said Twilight, and she went up to the blackboard , took the chalk from Celestia, and drew a flaccid penis.

"Very good, my dear student" said Celestia. "Now, have you ever seen that get bigger at all?"

"No" said Twilight, "but doesn't your butt keep getting bigger and bigger as you eat more and more cake?"

"Yes, yes, that's true. Maybe I could use that statement as I demonstrate." said Celestia, her mane turning lavender again.

"Demonstrate?" asked Twilight. "Demonstrate what?"

"Oh, nothing" Celestia said as her mane changed back to its natural hue. She continued her teaching. "Now, for the mare. The process begins when the mare begins to please the stallion sexually. This is called seduction."

"What's that?" asked Twilight.

"The mare will seduce the stallion by acting all flirty around him. She will do things such as say sexy pick up lines, spread open her legs, point to her vagina, and moan."

Then Twilight asked, "And how does this relate to the peeing?"

"Well" said Celestia, "the seduction by the mare causes the stallion's penis to erect."

"Erect? What's that?"

"The penis grows and gets hard, and it looks like this." said Celestia, drawing a boner on the chalkboard. "This is called an erection."

"Eeeew!" groaned Twilight, disgusted by the imagery.

"Here's where the fun begins!" said Celestia, drawing a vagina above the erect penis. "Now, the stallion will insert his erection into the mare's vagina." Celestia drew an arrow fromthe penis to the vagina.

"And then he pees in her, right?" asked Twilight.

"No, not quite that." said Celestia. "The stallion proceeds to thrust his penis into the mare's vagina multiple times. This sequence can take from ten seconds up to a half hour."

"Really?"

"Yes. And then, after quite some thrusting, the stallion will climax."

"Does that mean peeing?" asked Twilight again.

"Not quite. Instead of pee coming out, this clear, hot thick gluey substance oozes out of the penis and into the vagina, which does the same." Celestia dream drops coming out of the penis and the vagina. "After this occurs, an orgasm, or feeling of extreme pleasure, overcomes both the stallion and the mare. This can take a few seconds to an entire night. And after that, it's done."

"Thanks for letting me know that!" said Twilight, and she began to leave.

"Hey, you sit back down!" yelled Celestia demandingly.

"Why?" asked Twilight.

"Because now I'm going to demonstrate! observe." said Celestia in a perverted tone, smiling and lowering her eyelids halfway. Then she yelled, "Butler!"

Twilight was confused. "Huh?" she said as Celestia's butler ran into the room.

"How may I assist you, Princess?" the butler asked. Celestia lay on her bed.

"Well" said Celestia, "for the first time it's not cake... hehe..."

"Oh? Then what is it this time?"

"You see, the reason I don't want cake this time around is because the more I eat, the royal plot keeps getting bigger" said Celestia, turning her butt to face the butler, whose eyes widened. Once again, Celestia's mane began turning lavender.

"Oh, I see, heh heh. So, what do you need?" said the butler, blushing.

"I really need a massage for my plot. You know, something that will make me feel so much pleasure... ooohhh..." said Celestia, lying down on her back. Twilight saw Butler's penis erecting, just like Celestia had told her. This would help her learn! Celestia spread open her legs, revealing her glory hole. She started to stroke her hoof across it, moaning pleasurefully. "Oh, yess, oh, oh!" she moaned. Butler showed his length, which was now in full mass. "Go ahead, work my pussy." she said seductively. Butler stuck out his length and shoved it into her vagina. He began thrusting, slowly at first.

"Oh, you must really appreciate me... ugh, ugh, ugh" groaned Butler as he continued thrusting. He wondered why Celestia had given him such a privilege. He realized that she thought that he was very special, and that she wanted to show it.

"I'm learning Celestia!" shouted Twilight, and Butler looked at her.

"Oh, don't mind her, please" said Celestia. "Just move along." Butler began to thrust faster and faster as he felt Celestia's moistening vagina.

"OH, YES BABY! I LOVE YOU, PRINCESS!" Shouted Butler. Then he swung his hoof back, and slapped Celestia's left sun.

"OW!" she screamed in both pain and pleasure at the same time. Her sun turned red, and then Butler proceeded to spank her right sun. "OI!" she screamed again. Butler thrusted faster and faster, and it wasn't long until the climax.

"HERE IT COMES!" shouted Butler, and he cummed, his dick shooting out of her vagina, squirting out his magic glue. Celestia cummed too. They both calmed down and breathed heavily. Twilight knew that this was an orgasm. "Oh, yeah, that was worth it" said Butler again in his orgasm.

"I love you" said Celestia softly. Then she turned to Twilight. "Now, I hope you enjoyed that demonstration" she told her. "Now do you know?"

"Thanks for teaching me, I know a lot know, princess!" said Twilight enthusiastically, jumping up and down. Butler was all confused now.

"Wait, this was a DEMONSTRATION?" said Butler in surprise.

"Yes, Butler" said Celestia. "Asked the same question to Lauren when I was your age, Twilight. And this is how she let me know!"

"Who's Lauren?" asked Twilight.
