The Power of Dragon Mating

After Twilight had gotten her fittings for her night with Spike finished she said, "Thanks Rarity, I'm sure he'll like these" Before leaving and heading towards her library. When she opened the door, she saw books all over the floor. She picked one up and said, "Who would toss our books all over the floor? Wait, these are... oh my gosh! When did we get books like these!?" she couldn't believe that the books on the floor were erotic fiction books. "Wait... Spike! Please be okay..." she said quietly as she ran upstairs. She saw Spike crying on his bed and asked, "Spike... are you okay?"

Spike looked up at her still crying, "I don't understand it Twilight, why am I having these thoughts and these horrible dreams?"

Twilight put and hand on his shoulder and said, "Don't worry Spike, you'll get through this, I promise. Why don't you go get us some snacks from Sugarcube Corner?"

Spike smiled and left towards Sugarcube Corner, and when he did, Twilight called Pinkie and told her to distract him while she gets herself and the library ready. She set up one of the rooms to look like a teacher's office and left a bag with a note on it for Spike then went to get changed.

When Spike returned, he looked like he was sick to his stomach. He asked himself, "I don't understand why Pinkie tried to sell me everything in the shop. Huh, where's Twilight?" He saw the bag and read the note which said, "Put this on and wait for me upstairs, I think you'll enjoy what I've got planned, Professor Spike. ;)" He blushed at the last part of the note and said to himself, "I have a bad feeling about this, but I'll at least try it." before putting on the cloths that were in the bag, including a pair of glasses.

He went upstairs and sat behind the desk that was there and waited for Twilight. After a few minutes, she knocked on the door and came in wearing a school girl's outfit with a white polo that exposes her midriff, and a plaid skirt. She said, "You wanted to see me Professor Spike?"

Spike cleared his throat and said, "Yes Miss Sparkle, have a seat." She sat down in the chair in a way where her skirt was lifted just enough to show her panties. "Now, I wanted to talk to you about your grades this year. They don't look good. If this keeps up, you'll have to be held back... again."

Twilight made a convincing whine saying, "Not again! My parents are going to kill me if I get held back a second time! There's got to be some way I can bring my grades up!"

Spike looked through the papers on his desk and said, "I'm afraid not Miss Sparkle, you've missed so many assignments, and the ones you have done are done so poorly that even if you got perfect scores on everything else this year, I don't think you'll be able to pass."

Twilight sighed, but then gave a seductive smile and said, "Perhaps there's some other way I could bring my grades up?" tugging her polo to show a nip slip.

Spike blushed and shook his head saying, "It's going to take more than flashing to get me to change your grade."

Twilight licked her lips getting up and moving to his side saying, "Oh really? What about this then?" she got underneath his desk and unzipped his pants, and started licking his cock.

Spike let out a soft moan and said, "That's a good start, let's see how far you can go."

As she continued, she eventually moved onto sucking it. Every once in a while, she would swirl her tongue around his cock. When Spike forced his cock all the way into her mouth, she felt herself gagging, but it stopped as she could feel his cum going down her throat. It tasted spicy, but it was also creamy and thick. As she pulled out she looked up to Spike, and swallowed before saying, "How was that Professor?"

Spike smiled saying, "It was a good warm up, and I'll give you points for swallowing, but I think I need to see a little more of your body before I'm convinced." he pulled her up and ripped her shirt off of her, revealing her D-cup breasts.

"P-Professor Spike! These uniforms are expensive you know!" Twilight yelled out in shock, still staying in character.

Spike chuckled and said, "Don't worry Miss Sparkle, I'll get you a new one, free of charge." before suckling on her nipple, twisting his snake like tongue around it.

Twilight moaned in pleasure and whispered, "Professor Spike... please... stick it in me..."

Spike smirked and said, "Not yet, not until I've covered your breasts in my seed." He pulled her and put her on the chair he sat in and leaned it back all the way. He rubbed his cock in between her breasts. "You might not be getting my cock in you yet, but I'll still give you something." he said moving his tail to her pussy and thrusting it in and out slow enough so as not to take her virginity with it. He wanted to save that for himself. "How does it feel Miss Sparkle?"

Twilight panted from pleasure, saying in between, "It... it feels great Professor!"

"Your tits don't feel that bad either, so soft and plush. I can't hold it back anymore!" he yelled in pleasure as he spread his cum all over Twilight's breasts. "Now for the fun part." he leaned the chair up a little so she was leaning back and he spread apart her legs before slipping his cock into her.

Twilight moaned, both in pain and pleasure, "It hurts... but it's even better than your tail Professor."

Spike moaned lightly saying, "Damn, you're really tight. If I keep this up, I won't be able to keep myself from cumming again."

Twilight wrapped her arms around his neck and pulled herself up to him, and whispered into his ear, "Do it Spike, cum inside me."

Spike blushed as she said this, but didn't hold back. He pounded her as hard as he could until he found himself close, "Twilight... I'm close again..."

Twilight smiled and said, "So am I... let's cum together..."

The two let out a scream of pleasure as they came together. Spike looked up at her and said, "So, is this your idea of helping me with those dreams I keep having? Cause if it is, I've gotta say, it's a good idea..."

Twilight nodded and kissed Spike on his cheek before saying, "Let's get ourselves cleaned up, Professor."

Back at the Castle, Celestia was watching the tape with Luna and said fingering herself, "If I had known he would grow up to be that big, I'd never had let him go with Twilight."

Luna huffed angrily, "I can't believe you agreed to let them do this Celestia, that could be one of us right now!"
