Spiked by Spike

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?"
