Strange sensations were dancing through Twilight's head. Even considering that it was a dream it felt strange, felt being the keyword. Perhaps this was the first time Twilight had ever been self-aware while dreaming. She gazed around at her surroundings, the whole area was dark blue and purple with spots of white above her, giving the appearance of a painted night sky.

"So this is what the inside of my head look's like, it's much warmer than I thought it would be" she thought to herself. Not only was it warm, it was getting warmer, so warm in fact that a sweat began to form at Twilight's brow. At that point a ball of light began to form at Twilight's crotch, a very hot ball of light.

"What is this!? I-I can't...!"

Twilight awoke in her bed, it was about 8 o'clock in the morning and light was pouring in through the window.

"What a bizarre dream... and I wonder why it was so hot," Twilight mumbled to herself. There was still some sweat lingering on her dark skin which she wiped with her pajama sleeve. "I guess I was just using too heavy of a blanket for summer," Twilight's thoughts were suddenly interrupted when she noticed a strange tightness at the front of her pajamas. Twilight quickly peered under her sheets only to see a 9" erection pitching a tent at the front of her pants.

"GAH!" she cried out.

"Twilight?!" yelled Spike from the kitchen. Twilight could hear him dashing up the stairs, and by instinct she covered up her groin area with as much blanket as she could to hide her new attachment. "Are you okay?!" shouted Spike as he burst through the door.

"O-Oh yeah, I just, uh, conked my noggin on the headboard when I woke up and it surprised me is all," responded Twilight.

"Is that it? Man you nearly gave me a heart attack."

"Sorry, by the way what are you doing up so early?" Twilight asked.

"Oh well I just thought I would make you some breakfast, seeing as it's your birthday and all." Twilight went a little wide eyed at this comment, in all the excitement she had completely forgotten that it was her birthday.

"Aww, that's so sweet of you, just let me get changed and use the bathroom and I'll be right down."

"Well I was just going to give you breakfast in bed" Spike said with a big smile.

"No! I mean, I uh, don't want to get the bed messy is all so I'll just eat at the table."

Twilight knew she could cover herself up from across the room, but if spike came anywhere near the bed, there could be problems. Also, nobody likes getting crumbs in the sheets.

"Well fine, just come down soon so it doesn't get cold," said Spike just before he returned to the kitchen.

Twilight didn't waste a moment, she grabbed a change of clothes and hurried into the bathroom. She made sure the door was locked and the blinds were closed before finally dropping her pants to inspect herself. Her erection hadn't gone down at all, still going strong even after almost getting exposed.

"Oh man oh man what happened? What am I going to do?! Okay I just need to analyze the situation" she thought to herself. The scared girl hesitantly reached down and touched her penis, it was quite sensitive and sent a chill up her spine as soon as her hand made contact with it. It was thick, dark, and intimidating, in fact Twilight even heard it roar! Well that actually came from a bobcat that was being transported to Fluttershy's house at that moment but that's beside the point.

Underneath her dick hung a large ball sack, which sent another chill as Twilight felt it with her other hand. These new sensations were too much for her and she quickly had to let go. Once again sweat began to form on her forehead, and Twilight began to breath heavily. That's when another thought popped into her head. She reached down below her sack and felt for her girl parts.

Gone.

She could only feel skin where there used to be a slit, the proof of her gender. She still had her feminine form, her curves, her hips, even her c-cup breasts were just as they had been before. Down on her crotch though she only had man parts. What did that make her? A woman? Was she a man now? The legendary hermaphrodite?

Sadly she didn't have time to contemplate it because that's when Spike called out to her announcing that breakfast was finished.

"Okay I'll be there in just a minute!"

"Oh crud, what am i going to do now?" the genius girl thought to herself.

Her erection hadn't gone down at all, in fact touching it had only made it worse, to the point that there was a drop of precum hanging at the tip. That was when Twilight got an idea, she could just tuck it into the waistband of her skirt and hold a book in front of the bulge. After all, she read books at the table all the time, it wouldn't be that weird... right?

Twilight discarded her pajamas and pulled on her purple shirt and lavender skirt. She had tried to wear her panties but her wiener was much too pert and so it only led to hurt.

She left her pajamas on the bathroom floor as she walked out which left them very heartbroken. Twilight had never left them in the bathroom like that and they began to wonder if she would ever wear them again. Grief washed over the pajamas as they were encompassed by the cold blackness of space. Eventually, they stopped thinking.

With a glow of her horn, Twilight was holding a book in front of her crotch and she was on her way to the kitchen table. When Twilight walked in the room Spike was immediately confused why Twilight was holding a book like that... but decided not to question it because hey, it's her birthday she can do what she wants. Twilight sat down and looked at her plate, one fried egg and a piece of toast.

"Sorry it's not much. When I started we only had three eggs, and I tried to cook two of them with my fire breath and well..." Spike trailed off at the end of his sentence.

In Canterlot, Princess Celestia was very confused about why her star pupil would send her two uncooked eggs, a piece of bread, and a glass of milk but she was far too busy to question it.

"Oh uh, it's fine don't worry about it" responded Twilight. There was silence for a few seconds, both of them feeling uncomfortable for different reasons.

Wanting to change the subject, Spike asked "so, uh, what book are you reading there?" Twilight realized then that, in her haste, she had forgotten to check what book she pulled from shelf.

"Sewing For Idiots" she read aloud. Twilight's heart sank at the thought of Spike thinking she was reading a book intended for idiots.

Spike gave her a quizzical look and asked "well that's... nice, but why?"

"Well I, uh I... was considering helping Rarity with some of her dresses. Yeah that's it."

"Oh but don't you think that's kind of a beginner book? You would need to be pretty great to be able to give Rarity any help. I mean she's smart, beautiful, nice..."

At that point Twilight stopped listening, she was becoming lost in her own thoughts. She had to figure out exactly this had happened, though she already knew she was dreading accepting it. She didn't have these man parts before she went to bed, and she didn't consciously cast a spell to change he body like this, so there was only one option left: sleep casting. She hadn't sleep cast in years, she thought she had gotten over that when she was ten. A demoralized feeling swept over Twilight's mind.

"Hey Twi, are you listening?"

"Huh?" Twilight had completely forgotten that Spike was talking to her. "Oh, sorry Spike... I just zoned out for a minute there. What were you saying?"

"I said that we still need to pick up the cup cakes and decorate the library for your party this afternoon. Everyone is coming over at 1, right?."

Oh crud, the party. Just another thing that had slipped the poor girl's mind in all the confusion this morning.

"Uh, okay yeah, why don't you go get the cupcakes and I'll set up the decorations while you're gone."

After breakfast Spike headed over to Sugar Cube Corner, and as soon he had stepped out the front door, Twilight began pouring through her books for an answer to her problem. Because if she couldn't get rid of her new attachment, it was shaping up to be a very, very long day.

Author's Note

This fic isn't going to be sex based, although I do plan for there to be a couple of scenes for that.

Lastly, this is my first fic so any constructive criticism is welcome.

Edit: I made some changes to the formatting as it was suggested by some other users.
