'Celestia, damn it! Not again!' Spike raged in his head.

The dragon's claws clenched the silver tray he was holding tighter as he approached the purple alicorn. The glasses on the tray clinked due to the tremors plaguing his arms despite his best efforts to stay calm and balanced, but he knew that it was all in vain. His efforts to ignore what was in front of him had been constantly failing him for the past few years, always progressively becoming worse as each day passed by. It was tolerable when he first started hitting puberty, but now at 19 years old it was pure torture.

"Oh, thank you Spike." Twilight said as he shakily placed the loaded tray on the table next to her books.

"No prob." Spike mumbled softly as he averted his gaze from her body. Despite his best efforts he couldn't help stealing a glance at his closest friend. As usual her attention was completely focused on the pile of books and papers in front of her, allowing Spike to look at her for as long as he wished if he wanted to. His quick peek was enough; all she wore was a pair of panties and a loose-fitting tank top that she had borrowed from Rarity. Thanks to Rarity's larger bust the top hung loose on Twilight's smaller frame, exposing more of her body than should be. But as usual, Twilight remained oblivious to her surroundings, especially Spike's reddened face and awkward stance.

"Need, uh... anything else? I'm getting kind of tired." Spike asked hesitantly.

Twilight shook her head, her eyes remaining on her work as she reached for one of the glasses Spike had brought up. "No thanks, I'm not going to be up much longer." she stated. "I'll be up there in a little bit."

Without another word Spike made his way out of the room and headed for his bed. As he pushed open the bedroom door he paused and looked silently into the room. Both his and Twilight's bed were on opposite sides of the room yet no sort of barrier was in place between the two. It always annoyed him that not only did Twilight leave the space between their beds vacant, but that she constantly declined to allow him to claim a bedroom of his own. 'I'm not a little kid anymore. Why does she always treat me like one still?'

With a huff of frustration, Spike trudged to his side of the room and changed into his pajamas before climbing into bed. Though the lights were off and his eyes were closed Spike found himself unable to fall asleep, his mind filled with nothing but Twilight around the castle. Eating breakfast with only a towel wrapped around her still wet body, reading and studying in outfits similar to what she had on tonight, even exercising and stretching every morning in nothing more than her underwear... sometimes...

Spike's ears picked up the sound of Twilight approaching. He glanced over to the clock next to his bed and saw that he had been lying awake for a little over an hour. The bedroom door slowly opened and Twilight entered. Her horn glowed dimly, lighting the way just enough for her to navigate her way through the quiet halls and the dark room, but also illuminated her body in an almost hypnotic way. Spike couldn't help but turn his head towards her and watch as she walked towards her bed, wondering once more if the light wasn't enough to illuminate his side of the room enough for her to see him or if she just didn't care. Whatever the answer, Twilight stopped at the foot of her bed and slowly lifted her tank top up off her body and over her head. Spikes eyes remained locked onto Twilight's body, the contours of her upper body clearly visible to him; he could even see her nipples were erect. He continued watching her as she then slowly bent over and slipped her panties down her legs before kicking the flimsy garment aside and climbing into her own bed. As soon as she was settled under the sheets the glow of her horn dimmed, the room barely lit by the light of the moon.

It wasn't long before Twilight fell asleep but Spike remained wide awake. He tried closing his eyes once but his mind was bombarded by images of Twilight naked. This wasn't the first night he had seen his friend strip down right in front of him; in fact, it was a nightly occurrence that had gone on for almost as long as he could remember. He no longer tried to stop his erections whenever he watched Twilight preparing for bed... it was a battle he lost every time and always would. However, each night he grew more and more frustrated as he was unable to find a discreet way to relieve himself almost every night. He had already woken up Twilight a few times when he tried to jerk himself off under his sheets and he dared not to try it without some sort of cover, leaving him with no choice but to relieve himself when he was sure Twilight would be gone for long periods of time. For the most part it meant he only did so when Twilight was out of town, usually saving the day with the rest of their group of friends. However, there had been an extremely long period of calm over Equestria for almost a year, meaning Twilight had no need to leave town and could spend more time reading at home.

A lot more time.

Spike grimaced silently as he tried to ignore his throbbing hard-on. He spotted Twilight's discarded panties still on the floor and thought about retrieving them... surely they would still be warm from her wearing them all day, and her scent must be deeply embedded in the fabric, especially around the crotch-

'No. Get a hold of yourself.' Spike's conscious intervened. He flipped over to face the wall and shut his eyes again, hoping that sleep would eventually overcome him. He wanted nothing more than to give in and jump on top of her and ravage her, to satisfy the urges that currently went unfulfilled, but after restraining his instincts and wants for a while longer he finally managed to fall asleep, relief once more evading him.

"I'll see you later, Twilight. Have fun." Spike called out as he left the castle, not waiting for an answer. He didn't want to hang around for too long; Twilight and her friends were having another girls-night sleepover and Spike wanted to be far, far away from the gathering of girls. It was bad enough that Twilight tormented him every night but six sexy mares in their sleepwear would be too much for him to handle. Fluttershy thankfully dressed rather conservatively while Applejack and Rainbow Dash usually donned t-shirts and boxers. Pinkie Pie... no one could really predict what Pinkie Pie would show up in, but the main problem besides Twilight would always be Rarity. The outfits she wore left little to Spike's imagination, and on a few previous occasions she had worn outfits better slated for Hearts and Hooves Day. Then there was the matter of her outfits made from sheer fabric that she tended to share with Twilight-

'Stop it.' Spike reminded himself.

Taking a deep breath and filling his lungs with cool crisp air he headed off to his usual hangout spot. A brief fifteen minute walk brought him to his usual hangout spot, The Phoenix. Despite it being Ponyville's only bar it wasn't usually crowded, but it was a favorite gathering place for the few stallions that resided in town. Once he entered he headed straight for his normal table and ordered his usual. As soon as the bottle of Dos Equus arrived he quickly downed half the bottle in one gulp and ordered two more. His first drink was gone upon the waitress's return, and by the end of his first hour there he had polished off six bottles of beer.

"Yo Spike, what's up?" a voice suddenly called out.

Spike looked up and saw a familiar pegasus stallion had just come in and waved him over. "Hey Thunderlane, pull up a seat."

Thunderlane joined Spike at the table, ordering another round of drinks for the both of them and eyeing the waitress's rear as she walked back to the bar. "Should tap that soon." he muttered to himself before turning back to Spike. "You're here pretty late. Finally getting a day off tomorrow?" he inquired.

Spike huffed and took another large swig of his seventh beer. "Yeah, right, like I'd ever manage to get an extra day off. No, just had to get away from the castle for a bit, especially since Twi is having another sleepover tonight."

Thunderlane's ears perked up at the last bit of Spike's sentence. "Oh really?" he asked while leaning closer to the young dragon. "Is Rainbow Dash there?"

"Yeah, all of her friends are. Rainbow Dash, Pinkie Pie, Rarity, Fluttershy, and AJ." Spike listed off.

"You lucky little dragon, you." Thunderlane grinned, slapping Spike on the back. "So what the hay are you doing here instead of hanging out with those hot mares?"

"Trust me, it's not as fun as it sounds." Spike muttered in annoyance. Thunderlane raised an eyebrow in doubt so Spike continued. "It's bad enough Rarity still teases me almost every time I see her, but having all six of the girls together is worse than you can imagine. I mean, I can barely stand the torture Twilight puts me through just by herself. I mean, come on! Spending almost every second at home in just her underwear is too much!"

Thunderlane couldn't help but smile as he pictured Princess Twilight strutting around her castle in mere lingerie. "She does that everyday?" he asked trying to sound sympathetic.

Spike nodded. "I know it's our home and all, but she still thinks I'm just a kid. She doesn't see me as an adult dragon with... certain needs."

Thunderlane placed a sympathetic arm around Spike. "Have you tried anything with her?" he slyly asked.

Spike was mid-drink when Thunderlane spoke, causing him to choke on his beer and cough violently. "What? Of course not!" he said once he caught his breath. "She's like a sister to me. It's... that kind of stuff is just wrong."

"You weren't saying that during that threesome with those spa sisters." Thunderlane reminded him.

"Yeah, but... yeah." Spike gave in, remembering how he spent his 18th birthday at the town spa receiving a very 'special' treatment, courtesy of Thunderlane and Big Mac.

"Come on, you gotta admit she's one of the hottest girls in town. And you get to see her like nopony else can!" Thunderlane added.

With the alcohol helping to cloud his mind, Spike nodded after a few moments. "Okay, yeah. I'd... she is hot." he admitted.

"You're damn right, she is." Thunderlane agreed, taking a large swig of his own bottle. "Seriously, you're the luckiest guy in Equestria, living with her. I'd pay out the plot for a glimpse of what you get to see, you lucky bastard."

"It's not that much fun since I can't do anything about it. She'd probably have Princess Celestia banish me if she caught me." Spike said somewhat sourly, recalling how many painful nights he had gone through.

Thunderlane looked like he was deep in thought for a few moments before he reached into his pocket and brought something out enclosed in his hand. "Would you?"

"...huh?" Spike asked, caught off guard by Thunderlane's odd question.

Thunderlane leaned in closer to Spike. "If you could do something with Princess Twilight and nopony would ever know about it, even her, would you?" he asked in a hushed tone.

Spike sat in silence as his brain processed Thunderlane's question. 'Not even she would know- no! There's no way something like that could ever happen. But if it could... I mean, it's normal, right? Twilight is a hot mare, and I do get to see her... like that... every night...

Thunderlane grinned as Spike nodded his head once. "Heh, what guy wouldn't?" he chuckled while he patted Spike's back.

As Thunderlane's hand moved back he skillfully dropped a small bottle into Spike's open shirt pocket but before Spike could investigate what was inside Thunderlane stopped him. "What's-"

Thunderlane brought a finger to his lips and winked at Spike. "One should give you six hours. And of course, I trust this will remain a secret between just us bros." he said before getting up. "Whelp, better get on home. Got work in the morning. Have fun.'

Spike sat alone for a few moments as he tried his best to collect his thoughts and figure out what exactly just happened. He eventually glanced at his watch and saw it was already past one in the morning. 'The girls must be asleep by now.' he thought. Once his bar tab was settled he got up and trudged home, making sure to take his time walking back. When he finally arrived back at the castle he smiled as only silence greeted him; a quick peek into the living room showed all six mares were fast asleep in their sleeping bags by the fireplace. He quickly scurried up to his room and shut the door behind him, glad that for the first time in many months he finally had the room to himself.

Cautiously, he extracted the bottle that Thunderlane had dropped in his pocket and inspected it closely. It was the same type of bottle doctors normally put prescription pills in but this bottle had no label on it. However, there were about a dozen round white pills with a small horseshoe stamped on each one, though Spike didn't recognize the symbol to determine what it was. 'I'm sure it's in one of Twilight's medical books.' Spike thought, but he had absolutely no intention of bothering to flip through hundreds of pages anytime soon. Instead he opened his bedside table drawer and tossed the bottle inside before clambering into bed.

'I'll have to ask Thunderlane about those pills next time I see him.' Spike thought as he drifted off to bed. However, it wasn't a top priority task to do in Spike's head, and as the young dragon drifted off deep into slumber his memory to do so drifted off deep into the depths of oblivion.

3 weeks later...

Twilight sat hunched over her desk, the top of it strewn with loose pieces of parchment, piles of books, and quills too worn out from use for any further use. Scattered around where she was seated were more piles of books, some left splayed open while others formed piles higher than the average pony. However, the mess in Twilight's study went completely unnoticed by the purple alicorn. She was too engrossed in her latest project, made even more obvious by her lack of any clothing besides her bra and underwear.

"If I... then this goes... but then... arrgh!" Twilight groaned in frustration. She angrily drew a large 'X' over yet another failed theoretical spell and wiped the parchment aside, no longer caring where it landed in proximity to the overflowing trash bin next to her desk.

"I was sure that..." Twilight mumbled as she levitated six books in front of her and began scanning the pages in no certain order. She managed a small smile as she enjoyed not having Spike around to complain; he was spending the night over at Sweet Apple Acres to help Applejack and Big Mac fix their tractor. No doubt he would be trying to talk her out of spending all day- well, the past three days trying to deconstruct Bont the Viscous' formula on the ideal cloud construction as well as any ways to further maximize the water capacity of the clouds made in Cloudsdale using any new discoveries she made. However, all the solutions she had come up with had only decreased the average cloud's water capacity or made the clouds too unstable for use.

With another new piece of parchment in front of her, Twilight began scribbling her equation once more, trying to decipher where she went wrong once more. A sudden sharp twinge flashed through her head, causing her to drop her quill and rub her head to try to subside the sudden severe headache.

'I guess I finally overdid it.' Twilight sighed. The sudden pain in her head had always been the final telltale sign that she had overworked herself, and the pain would only become worse until she finally got some sleep. A quick glance at the clock showed just how long she had been at work; it was almost 3 AM, meaning she had been awake for almost 22 hours doing nothing but writing and reading, for the third day in a row. Still, being unable to solve the problem (never mind that there may not be a better answer than the one already in use by the Weather Team) was bugging her inside, and with great reluctance she grabbed a few blank pieces of parchment before heading to bed in defeat.

Once back in her room she simply fell face first onto her bed. There was no need for her to change out of her day clothes since she spent the whole day in just her bra and panties once again. With Spike out of the castle the entire day and not due back until tomorrow, plus the fact that there was an extremely minuscule chance of anypony coming over to visit, Twilight easily concluded that the time spent dressing herself would be much better used to instead increase her studying time. She let out a muffled groan into her comforter as she began pulling herself correctly into bed, but just as she was almost in bed a fresh spark flickered in her mind.

"Wait! If the cloud base is the temperature minus dewpoint, then divide that by 4.4, then... nnh!"

Twilight grasped her head again as another bolt of pain shot through her head. She was so close to solving an important piece of the elusive equation but this damn headache was stopping her from being able to fully concentrate. Afraid that she would lose her train of thought if she waited until she woke up, she quickly jumped out of bed to search for something to help ease her mind for just a few critical moments.

"I think I have some medicine all the way bathroom, but Spike should have... aha!" she cried triumphantly, pulling out a bottle of pills from Spike's bedside table. She quickly opened the bottle and used her magic to quickly gulp down one of the white pills inside, not bothering to wash it down with any water. Instead she quickly bounded back over to her bed and began scrawling her new idea on one of the pieces of parchment she had brought up with her. She smiled as her idea became clearer as her head began to feel lighter and lighter, but after a few minutes her concentration began to waver. Her eyes began to lose focus of her own writing and it wasn't much longer until the quill silently slipped from her broken magical grasp. No matter how hard she tried Twilight couldn't find the strength or concentration to pick up the quill again, and soon it became impossible for her to even keep her eyes open any longer. All the strength in her limbs seemed to disappear which caused her to fall onto her back, the whirling sensation in her head finally overpowering her and consuming her conscious state.

She was now out cold, her barely clothed body sprawled out on her bed, exposed to anypony who walked into her bedroom. Luckily nopony else was home to see her like this.

Until Spike returned home early.

2. More Problems

Spike slowly opened the front door just enough for him to slip inside, taking care to gently shut it behind himself. Waiting a few moments for his eyes to adjust to the darkness he began to quietly make his way towards his bedroom. As he passed Twilight's study he took a peek inside to make sure she hadn't fallen asleep at her desk yet again. Spike smiled when he saw her desk was vacant, a good sign that she actually went to bed. The last thing he needed was to carry her to bed once again; though he and the Apple siblings had fixed the tractor quicker than anticipated, it had been a very labor-intensive job that left all three of them very sore. Though AJ had offered to let him stay over for the night Spike had to decline the offer; things between him and Apple Bloom were still slightly awkward after last summer's creek mishap...

As he neared his destination Spike groaned when he saw the soft glow of light leaking out from under the bedroom door. 'What the... why in Celestia's name is she still awake at four in the morning?!' he thought. Suddenly he regretted not sleeping over at Sweet Apple Acres but it was too late to change his mind. 'Hopefully I can just go to bed and do whatever task she has in mind in the morning.'

Taking a deep breath Spike finally summoned the courage to enter the bedroom but couldn't help wincing, expecting to hear Twilight ask him to fetch Celestia-knows how many books from downstairs. However, only silence greeted him, though he soon spotted his roommate passed out amidst a few scrolls scattered around on her bed.

Spike chuckled softly to himself. "At least she made it back into the bedroom." he said as he headed over to his own bed, but as soon as his eyes fell onto a certain item he felt his heart drop like a rock.

'Shit! I forgot about those!' he panicked as he saw the bottle Thunderlane had given him on top of his bed. Glancing once back at Twilight, Spike opened the small container and quickly counted the pills inside.

One was missing.

'Oh fuck my- she couldn't have taken one, could she?' he thought in alarm. Quickly bottling the pills back up he rushed over to Twilight, unable to help looking over her barely-covered body before he gingerly touched her shoulder.

"H-hey, Twi, you awake? Twilight?" he called out, eventually shaking her lightly. There was no change in Twilight's steady breathing nor did she show any signs of coming to, strange since Twilight was a relatively light sleeper. A series of pokes to her side resulted in the same outcome; she was out cold.

Thunderlane's words from a few weeks ago came back to Spike's mind; "One should give you six hours". 'Are those... did I just drug Twilight?'

Picking up one of the stray pieces of parchment, Spike ran his hand over some of the words scribbled on it and saw that the ink was still just barely wet. 'She must have just passed out right before I got home.' he estimated. 'So I have about five hours before she comes to.' He sighed and began collecting the parchment pieces and quill to put away, but once he realized something he froze.

'I have five hours... to do whatever I want.'

Dropping the items in his hand Spike faced Twilight once again. His gaze covered Twilight's whole body; from her slender legs to her delicate neck, and everywhere in between.

Especially everywhere in between.

Spike soon couldn't take his eyes off of her toned, flat stomach. Just above it were her firm perky mammary mounds, and just below was no doubt her tight little fuck hole. Though he had seen her naked plenty of times there was still something completely mesmerizing and captivating about her barely clothed body, especially now that she was so vulnerable. So susceptible. So helpless...

Spike gulped, his mind exploding in conflict and turmoil as his conscious waged war with his primal instincts. Unfortunately for his morals, his body seemed to have already given in to his curiosity and desires and before he knew it his hand was pressed against her stomach, right over her belly button.

"Warm..." Spike muttered, dumbfounded by what he was doing. He knew he had to pull his hand back immediately, but his body refused to listen to reason. Instead, his hand began making small circular motions around her torso, allowing him to feel just how warm and soft her body was. He could feel the slight rise and fall of her body every time she took a breath of air, yet she showed no reaction to his touch or presence. It wasn't until his hand bumped up against the lower portion of her bra that Spike finally stopped his hand.

'That's enough Spike, don't push your luck. You should get to bed before you get caught.' he thought. Thankfully for his conscious, his lustful instincts actually agreed with him for once... for a split second.

'...you should get Twilight ready for bed first.'

'But she sleep nude every night! I can't strip her myself! She'd kill me!'

'So you're going to make her sleep in that uncomfortable bra? She's not even tucked in properly. What kind of friend would you be, leaving your best friend like that?'

Spike always hated it when the greedy side of him was right but he couldn't think of any response good enough to convince himself otherwise. "Just get her in bed. She won't know... hopefully." he repeated to himself a few more times before he managed to summon the courage to lift his hand off of her stomach and up to her bra. His worries of figuring out how to flip Twilight over to unclasp her bra were banished as he saw she was wearing a front clasp bra, but his ease quickly devolved into sheer terror as his trembling hand inched closer and closer to her chest.

'It's nothing you haven't seen before, Spike. It's just... you're just being a good friend, that's all.' he shakily thought as he finally came into contact with her clothing. He tried his best to ignore the pleasurable feeling of his fingers brushing up against the covered underside of Twilight's breasts and spent a few moments fumbling with the simple clasp before he finally managed to undo it. Spike couldn't help but be mesmerized as Twilight's bra fell open and her breasts spilled out into view. The next thing he knew he found his outstretched hand cupping one of her bare tits and gave it a gentle yet firm squeeze before he quickly pulled his arm back.

'What am I doing?!' he thought to himself in horror. He fully expected Twilight to sit up in anger and severely scold him for touching her like that, or maybe even attack him and have him imprisoned. However, only silence reached his ears and Twilight remained unmoving. '...I guess she really is out cold.'

Lust began to cloud Spike's judgement once more as he slowly reached out with both hands and gently cupped both of Twilight's firm mounds. "She's... they're so soft." he murmured as he carefully massaged her chest. He was surprised by how warm her breasts were in his hands, not to mention how soft they were despite always looking so firm. He even swore he felt her nipples hardening due to his touch. The longer Spike continued touching his closest friend the more he was growing addicted to her body. His previous annoyances with her exposing herself to him and unknowingly causing him so much pain vanished into thin air; heck, he'd gladly reorganize every book in the castle a different way every day if he got to touch her like this more often.

Spike had no idea how much time had passed before he managed to pull his eyes away from Twilight's chest. However, his gaze locked on to Twilight's barely covered mound in between her legs, almost causing him to start drooling. 'I wonder how she... feels... down there...' he couldn't help thinking. He gave Twilight's breasts one last squeeze before moving his hands down her body to her waist, his thumbs hooking themselves underneath the waistline of her underwear. Spike then remained still, not because he had a sudden change of heart, but because he couldn't remember why undressing Twilight was okay in the first place. Luckily for him the reason barely returned to his head after just a few minutes.

'Getting her ready for bed. Yeah, that was it.'

Still halfheartedly convinced that he was doing the right thing Spike slowly began to pull Twilight's panties down, but as soon as her naked slit came into view he lost his breath. 'She- she shaves down there?!' he finally managed to think. Now exposed to him was Twilight's pussy, with not a single hair on her mound to be seen. It wasn't uncommon for unicorns to use certain spells to keep their pubic region trimmed or partially shaven, but Twilight's was the first Spike had seen that was completely bare. Spike also found it odd that her privates looked slightly different than what he had seen in magazines or what glimpses he had of other mares; Twilight's inner labia lips were almost nonexistent, leaving the slit in her puffy outer lips as the only clue of where her foal hole lay. 'Maybe it's an alicorn thing...' Spike began to think before he quickly banished the thought from his head. It was already nervously arousing that he was seeing her naked form so up close... he didn't need to have these same thoughts every time he saw one of the other princesses.

Spike soon found himself kneeling down to get a closer look at Twilight's pussy. He tried spreading her legs to get a better view but of course her panties prevented him from doing so. Without any further hesitation he slipped her panties down her legs and tossed them aside before slowly moving her legs apart, this time finding success. As her crotch came into view Spike couldn't help but gaze in awe at what he saw.

"Fuck..." he said under his breath. As Twilight's legs parted her slit did so as well, revealing the small, fragile looking hole that led up to Twilight's womb. Despite Twilight being a full grown mare, especially now that she was an alicorn, her pussy looked so small for somepony her age. 'I mean, it's not like she's the most sexually active pony, but damn.' Spike thought.

Glancing down at his own crotch, Spike finally realized that his penis was fully erect and was now forming quite a large tent in his pants. "Fuck." he huffed again before unzipping his pants and lowering them just enough for his cock to spring out. He glanced twice between his own rock-hard erection and Twilight's exposed hole, having a hard time imagining he could fit inside of her. Ever since he hit puberty his body had grown larger than Twilight or even Princess Celestia had predicted, and though he was still able to function in society, rumors of his dragon heritage and 'assets' had some mares too terrified to even approach him.

With nopony around to witness his action, Spike tried his best to measure the girth of his cock with his hand before holding up the resulting 'O' up against Twilight's crotch. 'She'd be way too tight... right?' he guessed. He glanced around the room to ease his mind that he truly was alone before he took a deep breath, preparing himself to cross one of the final lines.

'Here it goes...' he gulped as he slowly moved his hand so he had one finger extended and pointed right at her pussy. Carefully, slowly, and as gently as he could, Spike began to let his finger probe her small entrance before letting it slip inside of her up to the first knuckle, stopping only to make sure he wasn't causing any damage to her body. Though she wasn't very wet her hole was very warm, and while he could feel it wrapped around his finger it wasn't overbearingly tight. He let his finger sink in more, stopping once he had sunken the entire length of his finger into her and relished the wonderful feeling. 'Not too bad. I wonder how it is with-'

Spike didn't get a chance to finish his thoughts as his body responded automatically. Pulling his lone finger out of her, Spike decided to attempt three digits to better gauge Twilight's capacity. At first it appeared that this second attempt would be too much for her body to handle; a quick coating of his own saliva proved to be just enough lubrication to get his fingers back inside of her.

'Wow, this is much tighter.' he grimaced as he barely managed to get two knuckles deep inside of her. 'It'd feel so good if my... was inside of...'

Withdrawing his hand once again, Spike stood back up and pulled Twilight's body slightly closer to the edge of the bed. He hastily shoved his pants all the way down and kicked them aside before he stepped closer and let the underside of his hard-on rub up against Twilight's crotch. He gave a few slow thrusts before he pressed forward until the base of his cock was where her tight little hole lay beneath his member, allowing him to roughly judge just how far his tool would penetrate inside of her.

"Wow. Almost to her belly button." Spike couldn't help but brag out loud.

He wondered if he would be able to fit his entire shaft into her or if she wouldn't be able to handle all of what he had to offer. He closed his eyes as he imagined her writhing underneath him, crying and shrieking as he pounded his cock into her body over and over again. "No, slow down Spike! You're so big, I can't handle all of it! You're cock is amazing, it's in so deep!" As he continued to imagine Twilight becoming addicted to his cock he began to stroke himself with his hand, occasionally opening his eyes to look at the naked real-life Twilight laid out in front of him. All of his pent up frustration and desire had been nearing peak levels before tonight, and as Spike imagined himself cumming inside of his closest friend he let out a growling moan and let his cum erupt from his cock.

The first heavy spurt of dragon semen was lobbed onto Twilight's stomach, filling her belly button with the white fluid. The second, third, and even fourth shot contained more power behind them and managed to launch themselves up to Twilight's exposed breasts and chest while a few stray splatters dotted her neck. Shots five and six lacked the volume and force of the previous ones and simply fell down onto Twilight's crotch before trickling down either side of her cunt and onto the edge of the bed sheets.

Panting hard as if he had just run a marathon, Spike wrung out the last bits of cum from his cock before he looked down to admire his work. He had just cum harder than her could remember and the amount of sperm present was surely more than enough to completely flood Twilight's womb, but as Spike's breathing returned to normal his sense of accomplishment began to evolve into horror.

"Oh fuck, that was good. That was... fuck. Oh fuck."

The gravity of what Spike had just done to Twilight hit him like a train. 'What have I done? I just... to her... oh fuck Celestia, I'm dead!' He quickly took of his shirt and began wiping his semen off of Twilight's body but the sticky cum was tougher to get out of her fur than expected. Most noticeable was the considerable deposit he had left on her stomach; the fur remained matted down and would surely remain stuck together once her body had dried. Even though she had been drugged he didn't want to risk waking her by somehow getting her to the bathroom and washing her body off, leaving him with no choice but to quickly soak a towel in warm water and clean off her body the best that he could.

"Gently... slow down, Spike." he said to himself as he washed her body clean. If he scrubbed too hard she would definitely notice the raw parts of her body when she woke, but if he wasn't thorough enough she would surely spot the dried semen on her. By the time Spike had finished clearing her body and disposed of any semen-covered evidence he could find he figured he had about an hour left before the drugs wore off. Wondering if he should try to redress Twilight, Spike quickly decided to just tuck her into bed as originally planned. Hopefully her memory after taking the drug was hazy and she would think she managed to climb into bed herself before he got home. After getting her back under her sheets he took one last very careful look around the room to make sure everything was as it should be before he finally made his way to his own bed.

"Oh." Spike sighed as he saw a familiar bottle still lying on the middle of his bed. He picked up the bottle and took a step towards the trash can before stopping. 'No, gotta get rid of these where nopony will ever find them.' he thought to himself as he carefully tucked the pills deeper in his bedside table. Giving one last sigh Spike finally turned off the light and climbed into his own bed, ignoring the lonesome feeling of no longer being able to touch somepony else's warm body. He closed his eyes and tried to fight off the barraging accusations his mind was bombarding him with, but there was no escaping the fact that he had crossed a line he never should have and whatever consequences came in the morning he would be facing alone.

All he could do now was wait.

8:19 AM

Spike's eyes remained shut despite his ears picking up the faint sound of somepony trying to wake him. As the voice grew louder and louder he groaned in exhaustion and forcibly cracked one eye barely open to see who apparently hated sleep so much.

"Bwaagh!" he yelled out in surprise as his vision was filled with Twilight's face. In a panic he bolted upright and fell backwards out of bed before he clamped his eyes shut once more. Surely the feeling of cold steel being clamped around his limbs was next to come as the Royal Guards arrested him. Or perhaps Twilight would just end his miserable existence right then and there before having his lifeless corpse dragged off to the edge of some desert-

"Spike? Are you okay?" Twilight asked, looking concerned while holding out a hand to help Spike back up.

Cautiously, Spike opened his eyes again and saw that... everything seemed normal. There were no guards in the room with them, Twilight wasn't poised to attack him; it was almost if...

...maybe he got away with it?

"Uh, yeah... yeah, I'm fine." he stammered as he stood up on his own. "What's going- er, how are you?"

Twilight's face broke out into a massive grin of triumph. "I did it, Spike! I finally managed to solve the formula! This is going to change weather in Equestria as we know it! I can't wait to tell Rainbow Dash, she's going to be so excited that cloud production is now going to be almost 40% more efficient!"

Besides the fact that Spike would normally have about as much enthusiasm over a cloud's production and carrying efficiency as Rainbow Dash herself he had a more pressing matter on his mind. "Are you, uh... are you feeling okay?" he asked her as he tried to calm his nerves and gauge how much she remembered from last night.

"I'm fine, Spike. Well, I didn't get to bed until three I think, but I don't feel tired at all." she said as she stretched her arms. Spike just noticed that Twilight was once again dressed in only a tank top and panties, and as she stretched her arms out her nipples could be seen through the thin fabric. Still, it didn't compare to what he had seen just hours ago, or what he had done to her...

"Spike?"

"Huh? What?" he said as his attention was brought back to the present.

"I said we should start packing for Cloudsdale." Twilight said as she began organizing what she wanted to take with her. "Once I deliver my findings to Weather Manager Cirro Stratus we can then begin working on deconstructing Trotson's thesis on molecular biology and-"

Spike's mind shut out the sound of Twilight talking; he was too busy feeling relieved that she seemed to have no idea what had gone on mere hours ago. Maybe, just maybe, he was in the clear.

3. No Going Back

Almost two months had gone by since Twilight had succeeded in improving the cloud formula. The weather factory management was of course ecstatic to be able to produce clouds that were more efficient and easier to produce and began work immediately to implement Twilight's findings. Rainbow Dash shared in the enthusiasm as well, mostly due to the fact that this meant she would have to work less.

"Hey Twilight, just got a message from Cloudsdale. Looks like they'll be able to start using the new clouds this spring." Spike called over to Twilight.

Twilight simply nodded as she was preoccupied with yet another pile of books in front of her; today she was researching the abilities of Poison Joke to see if there was any practical use for the devious plant. She didn't mind that this new project would be extremely difficult and slow as winter was approaching and, barring any unforeseen villains arriving, she didn't have much planned until spring when she was to examine the new clouds.

Spike on the other hoof was dreading Twilight's newest obsession. It had been troublesome enough that he had been tasked with gathering the dangerous plant and it was a miracle there were no mishaps related to its malicious affects. There was also the worry that most of whatever Twilight came up with would surely be tested on him since there were few visitors during the winter. He knew if he complained she would launch into her 28 minute long 'I have a spell that returns dragons to their normal state so there's nothing to be worried about' speech, and the spell did indeed negate any ill effects of practically any spell, potion, or poison, but it was still an experience he wasn't looking forward to.

Just as Spike finished returning yet another stack of books to their designated spots he heard Twilight groan softly. Looking over he saw her rubbing her temple, a sure sign that the end of a long workday was finally near. "You should get some rest, Twilight. You know those headaches only come once you've overexerted yourself." he stated.

Twilight nodded. "Yeah, you're right Spike. It's not like there's any rush to this, I guess, since it's just for fun."

Spike rolled his eyes at the fact that Twilight was willing to work so hard 'for fun'. "You should go upstairs. I'll put everything away for you." he offered.

Twilight smiled gratefully and patted him on the head as she passed him. "You're the best assistant ever, Spike. I'll see you upstairs."

Spike let out a sigh of relief as Twilight headed off to the bedroom. He was thankful for any night where Twilight went to bed first as it meant he could go to bed in peace without getting an eyeful of Twilight's body to make sleep almost impossible. However, it was no longer just the arousal he felt whenever he saw Twilight nude; he also felt pangs of guilt from the memory of what he did to her that night. Guilt, and a small bit of desire to have it again. Or more...

"Spike! Where's the medication for headaches?" Twilight called out.

"It should be in the bathro-" Spike began but was cut off.

"Nevermind!" Twilight shouted out. "I found your pills. Thanks Spike!"

The young dragon shrugged before resuming his task of replacing the books back in their place. About 15 seconds later realization hit him like two speeding trains colliding head on. He dropped the small pile of books he had in his hands and raced for the bedroom at breakneck speeds, hoping that he would be in time to prevent another disaster.

"Twiliiiiiiight!" he yelled as he screeched to a halt in front of the open door...

...just in time to see her put down an empty glass onto her own bedside table.

Twilight looked at Spike with a confused look. "Woah, calm down, Spike. What's wrong?" she asked.

"NOTHING!" Spike quickly shouted out before he managed to regain his composure. "Ahem, I mean, nothing. I, er... I just forgot where 'Plant and Potions 6th Edition' goes. But I think I put it back in the right place."

"It should be on the '2-5 years out of date but still relevant' shelf, next to 'South-East Equestria Herbiculture'." Twilight said before placing a stack of empty papers next to her bed.

"Yeah, right. I should, uh, go rebooks the place- replace the books!" Spike stammered as he scurried out of the room back to the library. Once there he sighed in annoyance as he saw a certain owl had beat him to it and was just placing the final stray book back onto its shelf before rotating his head to face the dragon.

"Hoo-hoot."

"Of course, the one time I actually wanted work to do." Spike muttered.

Owlowiscious simply gave a hoot of indifference, causing Spike to scowl. "Yeah, same to you, featherbag." he said as he turned to leave, flipping off the owl as he walked out of the library. Spike ignored the owl's response and made his way back to his room, his mind overwhelmed with one single question;

What would he do?

Spike saw that the lights were still on inside the bedroom. Cautiously approaching the doorway he peeked inside and saw that the pill had taken effect while he had been gone. Twilight was indeed once again passed out thanks to the pills from Thunderlane, but this time she had somehow wound up on Spike's bed. "Damn it." Spike muttered in annoyance. Sleeping in her bed wasn't a favorable choice for him as he always found her mattress too soft to sleep on, nor was sleeping on the couch in the living room. There was no denying he was drained of energy after working all day but he knew his only choice was to get Twilight back into her own bed, meaning it was up to him to prepare her himself yet again.

Despite Spike's attempt to reason otherwise he didn't feel nearly as much hesitance at the thought of undressing Twilight as he did weeks ago. Her outfit tonight of a simple pair of panties and a tank top would prove to be more complicated to remove but Spike he now knew that Twilight wouldn't wake for anything until the pills wore off. Shimmying her panties down her legs was just as easy and quick as he thought, allowing him to take in the sight of her exposed crotch yet again before he finally managed to pull his gaze away to work on her top. However, her tank top proved more difficult than her bra did before, especially since he couldn't simply just tear the item off of her body.

"Grrgh, come on!" Spike muttered in annoyance as he failed to get one of the straps off her arm. After a few more minutes of failure he climbed onto the bed and straddled her stomach as he gently lifted her upper body slightly with one arm. After some trial and error he finally managed to slip the straps free of her arms, allowing him to bend forward and remove her top completely. 'Yes!' Spike thought in triumph, pleased that his cunning was no match for Twilight's clothes, but his victory wasn't the only reason he felt so good. A quick glance downwards revealed that his semi-erect member was pressed against the unconscious mare's breasts, more than likely contributing most of the 'good feeling' he felt at the moment.

Unable to help himself Spike slowly drew his hips back and allowed his cock to nestle itself deeper in her cleavage. A few test thrusts back and forth raised his erection to full strength once more, but when he finally summoned the courage to reach down and push her tits together he couldn't help but let out a groan of pleasure. It felt so good to have her breasts enveloping his dick; her warm, soft body touching one of his most sensitive body parts, giving him more pleasure than he could recall. It wasn't long before all caution was thrown to the wind and Spike found himself grinding and thrusting himself against her chest at a moderate pace while squeezing and playing with Twilight's tits. As he gave a gentle pinch to both of her nipples he fantasized that she was gasping how large his dick was in between gasps of pleasure, begging for him to coat her breasts with... his...

"Woah!" Spike yelped out as he quickly pulled himself out of Twilight's intoxicating presence. He grabbed his cock and squeezed down on it, silently begging that the overwhelming throbbing went away before he created a mess he'd rather not have to clean up or explain in the morning. It was a nerve wracking few moments but the feeling eventually passed, allowing Spike to breathe a sigh of relief. Cumming all over Twilight's exposed body had been fun and erotic as Tartarus before, but the cleanup was a pain to do, and leaving her covered in cum... no matter how erotic the idea may be... was not worth the risk of what would happen if he were found out.

But Celestia-be-damned, he wanted to cum.

Unable to come up with any satisfying alternatives at the moment, Spike finally opted to get Twilight into her own bed. He first pulled back all the covers from Twilight's bed before he carefully lifted her up and carried her the short distance back. As he positioned her how she normally slept he soon found himself kneeling directly over her body, his chest just mere inches away from her own breasts, and his still erect penis was just above-

...no, now his cock was pressed up against her body, rubbing against her mound and lower abdomen.

Celestia's flank, Twilight's body felt so warm.

Spike knew he was in a bad spot, but damn it felt so good. Even though he had stopped himself from cumming before he felt his levels of pleasure building quicker than he had expected. Rubbing up against her crotch with his cock before had been an unforgettable experience, but doing so now with their bodies almost touching top to bottom was extremely more intimate. Finally, Spike allowed his arms to lower his chest down so he was directly in contact with Twilight's torso, her soft breasts squished against him.

Spike remained motionless for a few moments as his mind was flooded with lust and desire once more. By the time he gave his hips a small thrust forward he found Twilight's lower body was slick with his precum. Any feelings of guilt or worry were drowned out by how good he felt and soon he was once again dry humping away against her body. His mind once again wandered away to how Twilight may react to being filled with his member; would she whimper and writhe underneath him, or would she be more vocal and claw at his back as she tried to get him deeper inside of her? Soon his small uniform thrusts gave way to slightly jerkier, erratic movements in his hips and it wasn't long before one misguided movement caused his cock to slip out from its nestled place between their bodies.

Still lying on top of Twilight, Spike reached down to place his throbbing member back where it was until curiosity hit him. Shifting his lower body slightly he proceeded to rub the tip of his erection against her unprotected slit, quickly causing him to feel a shiver run down his spine as guilty pleasure dominated his head. His precum caused her crotch to become slick and slippery, and soon thoughts about trying to slip his cock inside of her began appearing...

'Just do it.'

'I... I can't. She's-'

'Out cold and will never find out.'

'But she's my... what if I hurt her?'

'She wants it. And you want it, too. You know you want to.'

By the time Spike's mind came back to reality he found himself rubbing the tip of his cock at Twilight's hidden entrance in small circles. He held his breath as he desperately sought any reason to stop now and pull away before it was too late but his mind had one more dark fact.

'She'll never know.'

Despite Spike's precum soaking the area around Twilight's slit he still found it difficult to begin penetrating her. He felt her body eventually give way and her tight love hole tightly embraced his invading rod as he continued to slowly slide it inside of her. Spike's mind went blank as he felt just how hot and tight Twilight's hole was; absolutely nothing compared to this feeling, not even the tit fucking he gave her just moments ago. It felt so good... why did he not do this sooner?

Spike was only 3 inches into her body when he felt the urge to cum returning rapidly. He still wasn't done his first full stroke into her but didn't fight the feeling this time. Instead, he gave one last jerk forward, embedding himself about halfway right before his cock spewed forth a torrent of sticky white fluid, coating the inside of Twilight's cunt and flooding her tight tunnel. Spike let out a few small grunts as he released the last bits of his load, not once caring at all that he had just cum inside of Twilight. His thoughts were still preoccupied with wondering if he could fully embed himself inside of her cunt, and thanks to his cum he now had all the lubrication he needed to do so. With his cock showing no signs of softening any time soon, Spike focused his attention back on the naked mare underneath him and resumed pushing forward, sinking himself into her hot, wet depths.

Though her hole remained tight, Spike's cum did indeed allow him to eventually bottom out inside of her, though he definitely felt the tip of his cock pressing up against something quite firmly deep inside of her. He remained motionless for almost a minute, basking in the feeling of having his entire shaft wrapped so tightly in something so hot.

'I'm doing it... I really did it. To her.' he thought in confliction. Now wasn't the time for Spike to suddenly find his morals, though, and he began to slowly pull back, stopping once he was barely inside her and pushed forward once more. Another groan of satisfaction escaped his lips as he hilted himself again, the second thrust just as pleasurable as the first. He then began to slowly move back and forth, taking nice long strokes to enjoy her body for as long as he could. He was in no rush to cum again.

"I can't believe I'm... with Twilight... like this..." Spike panted as his pace gradually increased. He found himself mesmerized by Twilight's tits bouncing back and forth every time he thrust forward and couldn't help but think how he had been unaffected by her perfect chest up until now. Countless stallions would spend every last bit they had to see the princess completely naked, yet here he was fucking her. Never again would he complain about her undressing in his presence; in fact, he may have to make sure he turned in to bed before Twilight every night from now on.

Spike was in absolute heaven; the only thing that could make the experience any better would have Twilight moaning and writhing underneath him, her pussy squeezing his cock ever time he thrust into her. He began to wonder how he might be able to convince her to allow him to fuck her while she was awake and perhaps allow him to indulge in some of his kinkier fantasies, and though he knew that such a scenario would never happen ever he still fantasized about what exactly he would do to her, increasing his speed as his thoughts ran on.

'I'd bet a million bits her asshole is even tighter. And her mouth, I'd love to have her sucking my dick. And I bet she'd let me try anything to her at least once. Maybe she'd even let me... film us... for later. And maybe... even...'

Before Spike could finish his last idea he let out yet another moan as he came once more. His arms wrapped around Twilight's neck as he thrust his hips forward as much as he could, grunting each time he shot a load of cum deep inside of her pussy. Even though it was his second orgasm in less than ten minutes he still managed to fire off six strong spurts of sperm into her womb, but once he felt his orgasm finally subside there was no denying the fact that he was exhausted. He let his arms give way and he collapsed on top of Twilight, his sweaty body pressed firmly against hers as he slowly caught his breath.

Once he finally managed to find the strength to prop himself up again with his arms he looked down at Twilight's face. She looked so peaceful and innocent despite the unsolicited ravaging she just took, and surely she would look just as exhausted as Spike had she been conscious and aware of what happened. Part of Spike's mind thought about trying round 3 closer to when the pill would wear off so she could wake up to him cumming inside of her, but he obviously knew that there was no way in Tartarus he could ever do that. Instead he took a few more moments to look down at her before he suddenly leaned down and kissed her on the lips, pulling back after a few seconds and finally getting off of the bed. There was no way Spike could clean out his cum from Twilight's body, and since there didn't seem to be any leaking out onto the bed he took one last look at her naked form before he finally tucked her in under the sheets and retreated to his own bed. Once he was settled in he looked once more over where Twilight lay before he turned his attention back to the bottle of pills by his pillow. He picked up the container and stared at its contents for almost a full hour before he finally made up his mind.

He knew what he had to do tomorrow.

The next evening...

"Hey Spike, over here!" Thunderlane called out, waving the dragon over to his table.

Spike waved in acknowledgement and took off his cloak before making his way over to the pegasus. He was glad to be able to get out of the chilly evening air but was slightly apprehensive about what he needed to talk to Thunderlane about. "Hey, what's up?" he simply asked as he sat down.

"Dude, it's been a while since you've come down here." Thunderlane stated before taking a long swig of his drink. "The Princess have you busy playing librarian again?"

"Uh, yeah." Spike said before getting straight to business. "Actually, about that... remember that, um, stuff you gave me a while back?"

Thunderlane pondered Spike's question before he was able to recall the event he was talking about. "Oh yeah, almost forgot about that." he chuckled before dropping his voice. "You end up using them?"

Spike's face turned slightly red as he answered. "Y-yeah, um... well, I mean..."

Spike went silent for a few moments as he summoned the courage for what he was about to do. Taking a deep breath, he looked Thunderlane in the eyes as he spoke.

"Do you have any more?" he finally asked.

Thunderlane couldn't help but smile. "Ah, well, they're a bit pricey, and I am currently low on supply. But... I'm sure we can work out some sort of deal. Your phone has a camera in it, right?"
