Spike was a gentle dragon. He respected everypony and if he did something wrong he would always say he was sorry. He helped Apple Jack buck apples, Pinkie Pie plan parties, Fluttershy with her animals, Rarity with her clothes, and Twilight with her studies. Even when he was relaxing and some one asked for his help he would help them. Sure it was hard working, but he always got something back in return for his duties no matter how many times he says he doesn't want anything in return. On his birthday they would go all out just for him. He was a good, honest, and noble friend to everypony. He loved everypony in Ponyville and everyone loved him. When he was all done for the day he would go home say goodnight to Twilight then go to sleep wearing a smile.

Spike is now a teenager and things started changing now. Sure he still helped people, but he would be less excited about doing it for he would always want to just stay at home and relax. He would sometimes even hide so no pony can find him. His friends were sometimes an exception, but he started seeing them in a new light...a sexual one. He used to respect mares, but he started growing curious about sex like what it would feel like to ram it in them and hear them moan for more. Every mare he come across he would stare at their butts. He even got slapped once for it and he told Twilight that he fell trying to fly. He even stole panties from a mares house once and still keeps it hidden somewhere. When he takes it out and looks at it he would think about how hot Rarity is in her dresses and instantly gets a boner. He would always have to get rid of his boner by...playing with his instrument. The urge to do it disgusted him every time, but he couldn't resist. He still had a crush on rarity, but it wasn't just because of her beauty, it was because of her curves. Instead of really helping Rarity now he also came to get a glimpse of her butt and breast. He would blush at the sight of them both moving and jiggling as she walked. He would imagine eating her out and pleasuring her to no end. He hated himself for it because Rarity is a lady and she was far from such slutty antics.

"She is may be a lady, but she is my lady" Spike said "And no one is going to satisfy her, but me."

He also started to think of men in Ponyville as enemies and rivals. He would see a man talking to Rarity and he would get jealous at the sight. Twilight would see this and comfort him and that helped a little. He would get rid of them by lying to them or threatening them. As a teenager he would let his anger out by turning anything he can on fire. He almost burned the Mayor so Twilight had to scold him and sent him home while he cussed at them in whispers.

One morning, Spike woke up a little tired after his session last night which kept him up. He reluctantly went down stairs to make him and Twilight's breakfast. He hated doing this for he now felt like her slave doing chores everyday for her. When he was done he put the plates on the table and yelled

"Twilight breakfast is ready!"

"Hold on I'll be there in a second" Twilight replied.

He heard her in the library and knew she was going to be awhile so he just decided to eat his meal by himself. He gulped down his food and placed his plate in the sink. He did not feel like washing the dishes that day and he just dreaded on the fact that Twilight was going to mention it. He went to go look for Twilight in the library to see what she was doing up so early.

"Twilight what are you do..." Spike Paused.

He saw Twilight looking for a book with her rump pointed right at him. He never noticed until now that Twilight's butt has actually gotten bigger since he was a baby. It was because he thought of her as a sibling or mother and never bothered to even take a glance. The thought of himself looking at it disgusted him before, but now he cursed himself for not taking a look. He couldn't tell If it was bigger than Rarity's butt, but he didn't want to compare or at least not at the moment. He also noticed that twilight was wearing the panties he stole from a mare a long time ago. His face instantly dropped when he noticed.

"Where did you find that?!"Spike asked worriedly.

"What... oh this?" Twilight asked.

She shook her rump a little without knowing what the effect it had on Spike as his tongue now hanged out of his mouth.

"I found it under all your clothes and didn't know who it belonged to so I decided to try it on, they are pretty comfortable" Twilight said looking at Spike.

Spike saw they didn't fit on her well for it made a little of her butt crack visible, but Spike kept quiet about it. Twilight turned back to the bookshelf.

"I was just looking for a book called "The Lustful Dragon" have you seen it?" Twilight asked.

"He's right here" Spike whispered.

"What was that?" Twilight responded.

"Nothing...haven't seen it...bye!" Spike stammered and took off.

"Now that I think about it, what was it doing under all his clothes?" Twilight thought "I might have to talk to him about this later"

Spike went to his room and closed the door as he went in. He panted and locked the door behind him. He knew that he wanted to touch Twilight's ass and that he wanted to fuck her. He never felt this way about Twilight before and he was freaked out by the thought. He didn't want to do it because his heart was set at getting Rarity, but he thought may be he could use her as practice. Sure he thought it would be nice to have Rarity be his first, but what if he isn't good enough at having sex. What if she says he sucks at having sex or says he has a tiny dick. It was a weird thing for Spike to think, but he knew it could happen so he needed feedback. He didn't have to cum inside of Twilight he thought, he could save the honor of filling his favorite mare with his dragon sperm. It wasn't going to be easy and he had no idea what he was getting himself into or how he is going to pull it off. He also thought may be when he gets done with Twilight he could move on to a different mare like Rainbow, but he didn't want to push his luck. He jumped on his bed and reached for a picture of Twilight and stared at it with a smile.

"You're not technically my mom or sister" Spike said to himself "Rarity can wait, I'll practice my skills on you my slutty nerd."
