"That's it I have had enough!" Spike yelled. Today was the day he finally snapped. Ever since he was a baby he had been Twilight's assistant. He cooked for her, found the books she wanted, cleaned the library, and even let her try her magic on him. Today was the day he finally got what he wanted and Twilight was going to do what he wanted for a change.
Looking around the room, everything was set. A couple of years ago Spike had gone to Canterlot and spent six months there learning from the few other dragons that had been brought up in pony society. They were older than him but served the same function of being assistants to high ranking unicorns. He had learned a lot from them about being a dragon but the best thing he had learned was that with proper instruction dragons has some limited use of magic. Even the most powerful dragon couldn't compete with an average unicorn in terms of versatility, but what dragons lacked in quantity they made up for in quality. Spike was able to perfectly execute the spells he knew every time and he had learned them without as much practice as Twilight had to put in. He could levitate objects to him, use the "come to life" spell, and give himself a mustache. Although his current favorite spell was not one taught to him by the other dragons but one taught to him by none other than Shining Armor himself. While he was sure the stallion would not appreciate what he was about to do with the spell he couldn't help but take a moment to mentally thank the unicorn. It had taken some modifications and a few extra steps but he was confident that even with the changes he was about to make, the spell was going to work flawlessly.
Twilight stretched her arms above her head as she slowly made her way back to the library. It had been a long day at the apple's farm helping them make their newest batch of pies. It had been worth it just to see Big Macintosh in an apron using a rolling pin to roll out the crusts. She laughed at the memory having not expected Applejack's brother to take part in the activity. Owlowiscious was over by Fluttershy's for a sleepover, so that would leave just her and Spike in the library. It had been quite a while since they had had any time for just the two of them. She knew she should set aside more time to spend with him, but somehow that particular item never seemed to make it to the top of her many lists. "Yes, I think this is just what we need." Twilight said to no one in particular. After Spike had come back from his time in Canterlot he had changed quite a bit. He returned much more mature both mentally and physically. Twilight thought that their working relationship was better than ever. She had told him before that he was her number one assistant, but now she was pretty sure she could call him the best assistant in all of Equestria and not be called a liar. He seemed to anticipate her needs before she even knew what they were. The physical changes were nothing to overlook either, he had grown taller than her and filled out quite nicely, losing the baby fat from his youth. His scales were really a very handsome shade of purple, and his claws looked just about the right size to grip…Twilight blushed at her own thoughts. Get a hold of yourself mare, she told herself. She was pretty sure Spike wasn't thinking of her that way, although he doesn't seem to have that crush on Rarity anymore, she thought. Twilight sighed at her situation, having a hopeless crush was difficult and she often wondered how Spike had done it when he was little. Lately he seemed more stand offish than he had ever been before. "Maybe I should have said yes to one of the times he had asked me to dinner." Twilight mused. What difference would it make getting food somewhere else when there was perfectly good food at home along with friends to share it with? Maybe Spike just wanted some time to be with me alone Twilight thought. It was true their friends were over often and if that wasn't the case then Twilight was out with them. Tonight was perhaps going to be just what the both of them needed.
Twilight saw she was approaching the library and felt very pleased with herself. She looked down at the small package she had picked up from the Cake's, it held Spike's favorites a ruby cupcake and a diamond cream puff. She had also been rehearsing a small apology to Spike and a promise to spend more time with him. While it was going to be difficult for her she had started to steel herself against whatever feelings she had in order to make Spike happy. She opened the door to only be greeted with darkness. "Spike?" she called. "I'm up here Twilight." Spike answered. His voice came to her from the direction of his room. Once he had outgrown his basket it seemed more natural to give him his own room than to make him keep sharing hers. Maybe I should have given him the option of sharing my bed, the unicorn thought. She felt heat invade her cheeks as she climbed the stairs, now regretting even having the thought and just hoped Spike wouldn't notice her current embarrassment. As she arrived at the top of the stairs she noticed that his door was closed so she knocked. "I thought we could spend some time together just the two of us tonight, and I brought your favorite from the Cake's sweet shop! Can I come in?" Twilight asked. Spike didn't' answer but the door did open and she happily trotted in looking forward to a night with a good friend. Once inside she heard the door slam behind her causing her to drop her package. Her entire body was then frozen. An immobilization spell? Twilight wondered.
Spike came into view holding a candle burning with a green flame and set it down on a nearby table. He picked up the box that had fallen and opened it. "Was this for me Twilight?" he asked, swiping some diamond laced cream onto his claw and popping it into his mouth. "Mmmm, my favorite," he commented as his eyes raked Twilights body, his voice taking on a husky tone to it. He set the treats down and began to rake his claws through twilights mane. "Wondering why you can't move? I'm sure you immediately figured out that this is an immobilization spell, taught to me by Shining Armor himself. Originally I learned it for your protection as an easy way to incapacitate an enemy," he told her. His claws straying from her mane to tease against her back. He continued on, "But recently I have been thinking of other more, unique ways of putting it to use. I have been able to highly modify this one for this particular use alone. I'm sure you noticed the candle, since my magic is all flame based it give me a way to anchor the spell as well as tap into it to modify at will. " Spike was fairly certain Twilight's face would have shown surprise followed by her thinking expression as a reaction to his words if she could have moved. "You see Twi I do a lot for you, and lately I feel as if I haven't been getting much in return. I have tried asking nicely, so tonight I am just going to take what I desire." While talking, Spike had rounded around behind Twilight and slapped her ass. He moved back around quickly and kissed her soundly on the mouth while reaching out and sticking a claw into the melted wax of the candle. Twilight felt her face relax as she was given conscious movement of it once again. She tried making a noise but found her vocal cords were still affected. Spike hadn't stopped kissing her while he made his modifications and Twilight found herself wanting to respond. Her previous feelings notwithstanding, his effortless use of magic and tone of voice were making him more attractive by the second. This wasn't the way she had envisioned acting on her feelings towards Spike, but he reasoned that he did deserve a reward for all the hard work he did for her. If this was the reward he wanted, who was she to deny him. She responded as much as she was able, closing her eyes and flicking her tongue against Spike's fangs. She felt Spike smile against her mouth as he deepened the kiss and pulled her closer to him. His claws found their way to her mane once again but this time he began teasing around her horn.
Once his hands touched her horn, Twilight felt heat spread throughout her body to settle low in her abdomen. He firmly stroked her horn in his confident hands and she was somewhat glad of the immobilization spell keeping her standing as her eyes rolled back into her head. Spike broke the kiss to peer down at her face, smirking at the expression he saw. "If you think that feels good wait until you feel this," he whispered into one of her ears. Suddenly his hand was replaced by something very warm and wet, Twilight's mouth opened in a silent scream at the pleasure surging through her. Spike knew no one had ever touched her horn in such a way before and wondered what she was feeling. Dipping a claw back into the wax of the burning candle he quickly heard music to his ears, Twilight was moaning out her pleasure with abandon. He set a slow but steady pace, occasionally wrapping his tongue completely around her horn. He reached down to fondle her marehood, finding it already wet and sensitive if Twilight's shrieks were any indication. While not exactly part of the original plan, Spike was not about to leave his lady wanting. He quickened his pace of both his mouth and claws, reveling in the noises emanating from Twilight's lips. He plunged two fingers inside of her body as he felt it quake around him. Guessing she was close, he wrapped his tongue around her horn and squeezed. He felt small bursts of magic against his tongue, and her body tightening around his fingers. Twilight panted as he slipped away from her body. "That was just the appetizer my little pony, the main course comes next," he huskily whispered into her ear.
Twilight felt the heat of a flame, it was warm but didn't burn her. Spike was breathing small bursts of fire, and she felt her body begin to shift towards the bed. Her eyes widened as she caught a glimpse of him performing his particular brand of magic. It was breathtaking how he could manipulate his flame to do his bidding. If she could have, Twilight knew she would have jumped Spike right then and there. She was very eager to find out the next phase of his plan. She felt herself settle onto the bed on her back with her head propped up by some pillows. He stood next to the bed and for the first time, she caught a glimpse of his dragonhood. It was a slightly darker shade of purple than the rest of him and larger than she had guessed. She unconsciously licked her lips at the sight. "See something you like dear Twilight?" he asked her. "Not to worry I'll give you something to occupy your delicious mouth." he promised. He moved onto the bed and straddled her chest sliding his dragonhood against her lips as she opened them to grant him access. He pressed into her mouth until he was completely engulfed and started to rock his hips. His body was flexible enough that he began sucking upon her horn again as she was sucking on him, mimicking the pace. Twilight moaned causing the vibrations to travel through him. Suddenly he removed himself from her mouth. "Now for what I have always wanted to do." Spike said breathily. He slid up over her head and positioned himself over her horn. Slowly he moved down taking all of her horn into himself.
He moaned at the feeling of fullness and thrust himself up and down against her. The feeling was so different to Twilight from his mouth that she didn't know how to react. The pleasure was almost too much as he began to move. She wished she could touch him somewhere else, needing to anchor herself against the sensations. Spike leaned up and blew out the candle, wanting to see what Twilight would do. She didn't disappoint him as she reached up and grabbed his tail before popping the end into her mouth and sucking. He propelled himself against her horn faster, "More Twilight." he moaned. She tried to calm her breathing as best she could and focus, to start performing some magic. He felt her horn begin to buzz within him causing Spike to cry out before he felt it spread outward to focus into his dragonhood. He panted as the pleasure he was experiencing began to reach it's peak. Twilight sucked roughly on his tail before crying out, "Oh Spike." He felt small bursts of uncontrolled magic pushing him over the edge with her. He rested for a moment before moving off of her horn and laying next to her. He viewed the contented look on Twilight's face as she snuggled closer to him, seemingly ready to fall asleep. He kissed her on the lips, "Guess what time it is now Twilight?" Spike asked her. His response was a tired "Hmmm?" He smiled before leaning in for a deep kiss, "Now, it's time for dessert."
Twilight's eyes opened as he climbed on top of her. "I don't think I have the energy to grab the box, you'll have to get it." Twilight said. Spike laughed, "The dessert I have in mind has nothing to do with what you bought." Twilight gasped as she felt something solid press into her hip. Spike attacked her lips with his own, massaging her tongue. He moved against her body, sliding his dragonhood against her marehood, feeling the slickness that had gathered there. "Are you ready Twilight?" Spike asked. "Yes, Spike please!" Twilight moaned. He thrust into her body, filling her completely. He stilled for a moment enjoying the sensation of being inside of Twilight before beginning a bruising pace. Slamming their bodies together and sealing his mouth over hers. Twilight wrapped her legs around him and moaned into his mouth feeling helpless against the onslaught. His tail snaked around hers and tugged slightly adding extra sensation. His thrusts slowed but became deeper as both enjoyed feeling the friction from the other's body. Twilight felt Spike swell inside of her, stretching her further and causing the passion to override everything else. Spike followed Twilight into bliss before collapsing on top of her and gingerly rolling to one side before pulling her close. He nuzzled his snout into her mane before sighing in contentment. "So," Twilight said quietly, "I'm not going to have to wait until you get fed up for that to happen again am I?" Spiked grinned, glad that they were on the same page. "What makes you think I'm finished?" Spiked growled. "I've been your assistant for years now, you still have a lot to pay me back for, and I've had a lot of time to envision my repayment." A shiver went down Twilight's spine as she imagined what Spike might have in mind. "I think this is going to be the best debt I have ever needed to settle."
