Spike smiled, humming softly to himself as he walked back to the locker he was renting. Sure the addition of those tall metal boxes made him think of a high school, but the cost per year definitely didn't. Thankfully his new friends had pulled some strings for him, so he didn't have to haul his heavy books back and forth from the college.

And all he had to do was service three futa mares for almost a month without pause or break. Sure things may have started off a bit fast for his liking, but it had worked out in the end and that's all that mattered to Spike. Even if that meant he had been fucked in just about every position imaginable over the last three and a half weeks.

Just thinking about it made Spike’s cock twitch and is hole ache for some hot, fresh dick. His mind went back to the last time he had been fucked only a day earlier by a certain prismatic pegasus.

She had interrupted him while he had been showering after a rather lengthy session with Pinkie Pie and Twilight. Being a former high school the showers were attached to the changing rooms which were in turn right near the entrance of the school as well as the auditorium. This meant the chance of getting heard and thus caught was high but evidently Rainbow Dash hadn't cared in the slightest.

She had just walked right in, forced the dragon to spread his legs and rutted him like the whore he had become. Never one to turn down a nice hard cock, Spike had taken it all without complaint, even though he had been rather surprised by the sudden intrusion. Spike couldn't help but think back to how the warm water had cascaded down his body while the pegasus fucked him fast and hard.

Though it made for poor lube, Spike had grown so used to taking fat horse cock that he was easily able to accept it all. It helped that Twilight had taken to pounding his slutty asshole at least once a day, stretching him constantly. With the unicorn’s help he could now easily take both Pinkie Pie and Rainbow Dash without complaint or almost any lubrication.

A fact that both ponies took advantage of by walking up to him, flipping his skirt up and jamming their cock up his ass. They hardly needed to ask for permission as both knew that the slutty dragon would let them have their way with him whenever they wanted.

And he loved every single second he spent on the end of their cocks.

Spike shook his head, and did his best to dismiss the memories that plagued him only for another to come to mind. It had been his first meeting with Pinkie Pie the day after he had joined the club, and the excitable pink pony had thrown him a party. His welcome to the club had been an incredibly fun affair, though there had been one part that he hadn't really expected.

Though in hindsight he probably should have.

Namely it was how each one of them minus Sunset had taken their turn fucking him, though not before Pinkie Pie got her turn. The earth pony was small, though her dick was still a few inches longer than Spike’s own, compared to the other club members, it was tiny. What she lacked in length as well as width, she made up for in monumental volume however, outclassing nearly everyone.

After only a few minutes of partying Pinkie Pie had taken him aside and asked to fuck him while they played games. A little shocked at the request, but more than a little excited, Spike had of course agreed. Nothing could prepare him for just how productive Pinkie Pie’s surprisingly small balls were though.

They didn't even need lube as the pony dripped pre cum like a broken faucet. A leak which quickly became a torrent after entering Spike fully and beginning to thrust into him. Throughout it all they played board games, laughed, and ate it cake while Spike was pumped full of jizz.

Though a little weird, Spike grew used to it, but that changed when he felt his stomach brush against the table. Only then did he realize that his belly had grown to the point that it felt like it might burst at any moment. Just thinking about that time and the weight of all that futa cum made Spike want to go find Pinkie and relive it all over again.

Pushing that thought from mind, Spike walked over to his locker and pulled it open. He was about to deposit his books into the metal confines of the rented space when he noticed something odd. A single slip of paper adorned with a wax seal sat atop his things, as if it had been slipped through the grate at the top.

“Huh, that's weird,” Spike murmured.

Grabbing the small slip of paper Spike sliced open the seal with a claw and began to read.

Greetings Spike.

I hope you are well and that you are available to help me out for a few hours. You see I have an important exam coming up and I tend to get rather… excited when put under such pressure. As such I was hoping you could assist me while I studied in the library. If so I will be waiting for you there.

Sunset Shimmer.

“How… formal,” Spike muttered to himself.

Spike immediately began to wonder just how big the younger futa mare was, especially given the hushed manner that her appendage was spoken of. Apparently no one could handle her when she was fully erect, and only Pinkie Pie was able to swallow a third of Sunset’s load. Everything about Sunset Shimmer’s male appendage was shrouded in mystery, with Twilight merely stating that they were stretching him out so that Sunset could use him as well.

I guess I’m ready for her now. Spike thought. I’ve certainly been fucked and stretched enough times. Heck I’ve swallowed litres of cum and managed to keep it all down.

The dragon deposited his books, closed the locker and spun the combination before walking away, a spring in his step. Excitement and nervousness warred within him, his intense lust battling against the hushed manner of which his clubmates spoke of Sunset. Intense, demanding, enormous, and with an output that put even Pinkie Pie to shame.

It was enough to make the young slut wonder if this was a good idea, though he was quickly reminded of his own still burning desire. With a needful heat blooming strong in his belly, Spike knew he couldn't turn back now. This was a challenge he would not back down from, especially given just how hungry for dick he had become.

Putting one foot in front of the other, Spike made a beeline towards the distant library. While he walked Spike couldn't help but wonder if the futa mare was going to use him in as public a setting as the others had. Each one of them seemed to have a kink for stealth sex, either that or they were simply so needy that it overwhelmed their sense of reason.

Either way Spike had quickly grown used to stifling his moans and generally keeping quiet while getting fucked. These skills had served him well, though the dragon had never thought he would need them in the first place. Either way Spike was looking forward to what Sunset Shimmer had in mind for him.

Making his way through the crowds of students which gathered in the halls, Spike quickly crossed campus. Upon reaching the large domed library, the dragon began to look around, starting at the darker, quieter section at the back. There he found several other students, a few empty study rooms, and a dozen large wooden desks with towering dividers between them.

It was here that he saw the familiar sight of a certain flaming haired mare who was nervously chewing on her pencil. Upon noticing that Spike was now standing next to her, Sunset Shimmer’s eyes went wide and she glanced from left then right.

“Oh thank goodness you’re here,” Sunset Shimmer whispered. “I assume you got my message?”

“I did,” Spike replied with a slight blush.

“So does that mean you will help me with my erm… problem?” Sunset asked.

Spike nodded. “You don't want to do it right here do you?”

“Well I was hoping we could,” Sunset Shimmer admitted. “The desks are really deep so I figured there was enough room.”

Spike glanced at the peice of furniture and guessed that there would indeed be enough room for him under it. Things wouldn't exactly be comfortable but the dividers went straight to the ground, meaning noone should be able to see him. Sound though, now that would be an entirely different problem altogether.

“I suppose there is,” Spike admitted. “Are you sure I can erm, take you?”

Sunset Shimmer nodded hastily. “I had hoped to test things in a more private setting but I’m afraid I’ve gotten so excited that I can't wait a moment longer.”

“Well then I better get to it then eh?” Spike remarked with a slight smirk.

Sunset Shimmer grinned. “Oh thank you Spike. After this exam I’d gladly tutor you in any subject you need help in.”

“That's not needed,” Spike cautioned.

“I insist,” Sunset Shimmer stated firmly.

Spike hummed. “That would be appreciated. Thanks.”

“Don't thank me yet,” Sunset Shimmer cautioned.

Spike lifted an eyebrow. “What is that supposed to mean?”

“You will see,” Sunset Shimmer answered, wiggling her chair back enough to allow Spike to slip underneath.

With one final shrug, Spike knelt down and crawled into the dark enclosed space. With three sides blocked off by wooden walls, Spike’s only source of illumination came from between Sunset Shimmer’s legs. Though enough for him to see clearly due to his draconic eyesight it took a few seconds to adjust to the gloom.

When that happened he was amazed to find that he was trapped in an enclosed space with an absolute monster of a cock. It was easily bigger then even Twilight’s penis with a girth that would put a baseball bat to shame. The sheer dimensions of the thing made Spike doubt that he was even awake at that very moment.

After giving himself a sharp smack across the face, the dragon reminded himself of why he was here and what he was supposed to do. No matter how monstrous her size, or titanic her emissions, the futa mare had trusted him to get a job done. Even if accomplishing that job would require him to stretch out his ass in a way that it had never been before.

Well that wasn't wholly true, his new friends had made sure to double and even triple team him on more then a few occasions. All while stuffing him so full of jizz that he had probably more cum then dragon by weight. Everything he had gone through had led up to this point, and though Spike still worried, he wasn't about to give up.

After inhaling a deep lungful of pungent air, Spike got to work by wrapping his hands around the beastly appendage. He started with stroking it as best as possible, but even that was difficult due to the fact that he couldn't even wrap a claw around the thing. Furthermore it took a few casual strokes before the dragon really accepted that what he was seeing was indeed real.

A soft gentle moan made Spike smile, and move a little closer, positioning his lips near the tip of Sunset’s cock. The heady aroma filled his senses, and made Spike want nothing more than to simply dive in. That would take time though as adapting his mouth and throat to such a beast would be a herculean effort.

After briefly psyching himself up, Spike slipped his lips around the head and began to stretch his jaws wide. Only to be surprised when he realized that such a task wasn't as hard as he had assumed it would have been. Time spent sucking off both Twilight and Rainbow Dash at the same time had ensured that he was ready for this moment.

With this thought in the back of his mind, Spike pushed onward, taking more and more of the mare’s cock. While he did this the dragon continued to stroke as much dick as possible, working the shaft to the best of his abilities. He hardly even paused as he passed the midway point, the thick horsecock sliding easily into his throat without issue.

The bulge it made would be easily visible, and Spike could feel it travel down his body as more of the futa mare’s cock slipped inside of him. Short breaks were necessary, but the futa slut had gotten so used to doing so that it was like second nature to him at that point. Within a minute he had reached as deep as Twilight had managed to get and then after a short pause, Spike pushed ever onwards.

Each new inch of cock which slid into his gullet passed the point that even Twilight had gotten, stretching him in ways he had never experienced before. It was like he was a virgin all over again, taking his first dick and being forced to adapt to strange new situations. Ignoring that thought, Spike readied himself for the last few inches, a sense of pride and accomplishment welling from within him.

After filling his lungs with much needed oxygen for one final time, he pushed his entire body forward. Then with a soft plap, his chin met Sunset Shimmer’s crotch and all two feet of her mammoth cock was inside of him. So huge was the mare’s meat that it felt like it had gone all the way through him and out the other side. That may not have been physically possible, but it sure felt like it anyway.

Sunset Shimmer seemed to be enjoying herself as well, with Spike able to hear her soft, almost feeble moans from his slightly awkward position. In that moment Spike knew that this wasn't enough for him, and more than that, it was not enough for Sunset. From the way she was moaning, to the soft throb of her cock and her bulging balls, it had evidently been quite some time for her.

She deserved to fuck his ass and dump her load directly into his guts.

He didn't pull back immediately though, using his long thin tongue to work her cock while he slowly ran out of air. Before that happened he sucked, slurped and worked her dick like the professional whore he had become. Only when his lungs began to burn did Spike begin to pull back.

And back and back some more.

Having to physically crawl backwards in order to unimpale himself on her massive horsecock. Once done, he breathed deep, stroking her shaft with one claw while the other searched through the pockets of his dress.

Finding the small bottle of lubricant wasn't hard, and he quickly applied a thin line of cool liquid to Sunset’s dick. He then bent over, pulled aside the pink lace panties he was wearing, and squirted the rest inside of himself. It felt weird, but Spike knew he would need it all if he was going to squeeze this beast into his soon to be ruined asshole.

After pulling his lips off the head of her dick, Spike swiftly turned, and expertly guided the mare’s shaft against his hole. The slightly confused moans from his partner turned into a surprised yelp when she felt the dragon push back against her. The head of her titanic horsecock entered easily enough, having made an audible popping sound after sliding inside.

The rest was much harder, and meant that Spike had to awkwardly crawl backwards with his ass raised up into the air. While this happened, he used one hand to brace himself against the wall while the other traced the beastly appendage as it traveled up his torso. The indent was so massive that he could even see it in the dim light, the first few inches dwarfing his own tiny dick by several orders of magnitude.

Spike grunted and scraped, the task of impaling himself on her cock taking a surprising toll from him. It was a difficult process, and one that necessitated several short stops in order to try and relax and loosen his tight hole. Sunset Shimmer didn't seem to mind, though she was a little too overwhelmed to say or do anything at that moment.

All she could manage to do was cling desperately to her desk, gritting her teeth as she felt her cock get squeezed into the vice like confines of Spike’s ass. Thankfully the dragon was nothing if not adaptable, and it didn't take long before he began to stretch around her. Despite the size and girth of her dick, Spike remembered well all the times he had his guts filled to the absolute brim.

Suddenly he was even more thankful for all those times he had been used by the three other futa mares. For it allowed him to push deeper and deeper with only short breaks to let his body shift around. Only at the halfway point did he stop for an extended period of time, taking a deep breath and feeling how far he had managed to get.

The bulge was incredibly far up his belly, and the dragon took a moment to relish in the small sense of accomplishment he felt. That wasn't the only thing he was enjoying however, as Sunset Shimmer’s soft moans had grown louder. If he listened they almost sounded like growls, exciting some part of him that enjoyed being dominated by someone bigger than him.

In this case only a single part of her was bigger, but that was the most important part in Spike’s mind.

After taking another deep breath, Spike braced himself against the walls of the box and pushed back hard. With more than a foot of dick stuffed up his backside, Spike once more reached the point that no one else had managed to get. This time he didn't hesitate, ramming his way past it and filling his ass with so much dick he could feel it lifting him off the ground.

Spike shuddered, a hand going to the now massive bulge that he could feel going all the way up to just under his ribs. The pleasure he felt was immense, and sure enough he came suddenly, shooting his load onto the library floor. He didn't care though, for all that mattered was the soft feeling of fur against ass which signalled that he had managed to get it all.

The position may have been awkward, and Spike knew he was going to get a cramp from it, but again, he didn't care. To service such a monster was worth any price, and any minor suffering he may experience.

With a grunt, he began to move in earnest.

Back and forth he went, using both his arms as well as his legs to fuck himself on Sunset Shimmer’s cock. With each time she bottomed out, Spike felt like another small part of him had been changed, altered somehow by the mammoth cock. Organs were pushed aside, and intestines straightened as his body was altered to better service such a beast.

In time he even began to relax, having adapted to her elephantine size after only a few minutes. Again he muttered a silent thanks to his new friends for having prepared him for this moment. Something Sunset Shimmer was sure to do as well once she wasn't struggling to not cry out in ecstasy for the entire library to hear.

She hadn't expected this, and it was obvious that she was only just barely managing to keep herself quiet. With one hoof pressed against her lips, and the other gripping the edge of the desk, Sunset Shimmer felt conflicted. On the one hand she felt amazing, and being able to get balls deep inside of her partner was as amazing as it was new to her. Though on the other, she had noticed that she was getting some odd looks from a few other people.

A sudden squeeze drew forth another moan, and she knew right then and there that she wouldn't put a stop to this moment. It was too good, and she would do anything for the dragon to keep doing what he was doing. A sentiment her and Spike shared even though they had not spoken a word to one another.

As time passed, Spike grew used to the odd position, and the way he was forced to crouch beneath the desk. It would never be comfortable, but it was at least tolerable. During this time he came more than a few times, his diminutive cock spurting thin, short ropes against the library floor.

Both of their moans had grown louder, with Sunset Shimmer having been forced to stuff a hoof into her mouth in order to stifle the sound. All attempts at studying were gone, and she even began to thrust along with Spike’s movements. Turning the dull slap of flesh meeting flesh into something clearly audible in the quiet space.

Neither cared, and as Sunset’s orgasm began to edge closer, she couldn't help but moan to her heart’s content. Knowing that it wouldn't be long, Spike picked up the pace, pushing himself to go as fast as possible.

Until all of a sudden, he felt it.

A single powerful throb was the only warning he got before Spike felt the first wave of cum shoot inside of him. A spurt so powerful and massive that it dwarfed the entire emission of a lesser pony in an instant. He could even feel the load as it traveled down Sunset Shimmer’s cock before exploding inside of him with all the force of a firehose.

Over and over he felt his insides stretch and balloon as he was forced to take a seemingly endless amount of futa cum. His own orgasm happened at about the same time, but it was an afterthought in the face of Sunset Shimmer’s eruption of seed. In seconds Spike could feel that he had become bigger then he had ever experienced before.

His belly was now so large that it pushed him up off the ground and made him look pregnant with triplets. Yet still it continued, filling him to the point that he began to worry if she would ever stop. Thankfully it wasn't quite endless, and after slowly trailing off, Sunset Shimmer’s cock fell still though it didn't shrink or soften in the slightest.

The futa mare sighed contentedly. “Thank you for that,” she whispered.

Spike grunted, too lust in a cum drunk haze to even form a coherent sentence.

“Are you okay down there?” Sunset Shimmer inquired.

“Yesh,” Spike slurred.

“Oh good. Because I was going to start studying again. Do you mind staying down there for a while longer? I wont cum again for a while so you don't have to worry about that,” Sunset Shimmer pressed.

“Hokay,” Spike replied.

“Wonderful. I’ll plug you up when I’m done, which should be in an hour or so,” Sunset Shimmer continued.

Spike didn't even care, and merely grunted again.

“Thanks again Spike,” Sunset Shimmer stated, wiggling her chair forward and sealing Spike into his wooden prison.

I love my life. Spike thought to himself.
