It was supposed to be a normal day. Twilight finished with all the university work and went home early to enjoy some break time with her son, Spike. He seemed so distant lately and it unnerved her a little. Ever since he got his wings and became an adult dragon, he would spend hours in his room. And each time he stepped outside, he was sweaty and very thirsty. He would steal a bottle of water, then rush off the washroom with all his blankets and that plushie of his.

Twilight didn't want to assume the worst, she was his mother after all. A little trust was always needed in this kind of relationship. But at the same time, he was acting very suspicious and she just had to know why. So the plan today was to surprise him with a massive dinner and party at Sugar Cube Corner. All she needed to do was convince him out of that room. This is why she rushed to finish her work early today. So she could the most amount of time needed.

Twilight walked into the castle quietly in case he was sleeping. Carefully, she moved up the stairs and over to the hallway leading to his room. Containing her joy, she moved slowly toward the door and cracked it open. All her plans were so close to being ready... and instantly, they all shattered upon what she saw on the other side.

Leering into Spike's room, the alicorn was left blushing bright at the dragon's enlarged cock standing out in full view. She jumped back, seeing such a thing was so wrong for her. He was her son, not some hot stud at the beach. But no matter how many times she slapped herself to get the image out, it wouldn't. It was there to stay, longing for her to look back inside. Her legs were like iron, and her head was as light as a feather upon landing back at the image.

It was quite the prize of dragon cock. The base was a huge and swollen knot, and bumps continued upward underlining the shaft. A bulging vein ran along the top and stopped at the head. It was a smooth and rounded cap, with a hole at the top. Her heart stop and her brain screamed at her to stop looking at her son's cock. She had studied dragon biology many times while raising him, but never realized just how real and amazing a dragon cock would be in real life.

The alicorn gulped loudly, trying not to make a sound. She was scared that anything could possibly alert the dragon inside. If she was caught, it would be the worst humiliation of both their lives. Twilight didn't even know how to react, so she just froze in place. Spike's hand came into view, proving much to her horror this wasn't some random morning wood moment. No, he very much pulled it out in full view.

His claws wrapped around the base and bounced it back and forth. This showed how firm and hard it truly was. Twilight felt her heart beat fast and hard against her chest. Her legs shook and her hips quivered like it was right in front of her. Her mouth opened and the alicorn could feel her tongue lolling out. They tried to fight such horrid and disgusting thoughts. This was her own son. She raised him from just a tiny egg.

Yet the next thing he did only add more to the strangeness. His Rarity Plushie came into view. Her eyes went so wide. No, he couldn't possibly be thinking that. Maybe he was just looking at it for the sake of having Rarity's image in his head. Yeah, that had to make sense. He always had a massive crush on Rarity. No surprise he would polish himself to her visage. As disgusting as that sounded, it was the only logic holding her mind together.

But things just kept getting worse as Spike pulled back on a flap under the plushie. Strange, Twilight never noticed that there before. What could possibly be hidden in there-- Her mind was instantly shut down as Spike dropped the opening over his meaty cock. Twilight watched, almost in slow motion, as the head entered the secret compartment. Her breathing became ragged and her hooves started to slip from the shock. She could feel a small trail of saliva coming down her chin.

The Rarity plushie's bottom expanded as the massive cock pushed upward. Twilight was left breathless as it managed to contain the entire length without ripping once. Her body started to heat up, making the air around her heavy and thick. The alicorn could see the bulge continue up and up the plushie until it stopped at the bow. The head of his cock pushed the fabric inward. Her eyes were drawn to the plushie's face deflated with each fuck. That expression seemed so wrong and yet so damn erotic.

Her son's cock continued to move in and out of the pocket. The dragon was growling, enjoying the tightness of the fabric around his cock. Twilight watched with her heart going crazy, each thrust leaving her so light-headed. He was grunting and huffing like he was fucking the actual mare. The way the plushie jiggled and danced was mesmerizing. It was almost like Rarity was there on top of him.

Things reached an absolute peak of strangeness when the plush started to moan. Twilight blinked twice over and reeled her head back in utter confusion. What was that noise? It sounded exactly like Rarity!! Did Spike put a voice box into it? Her sick and disgusting son had defiled the present Rarity gave him by not only fucking it but putting a voice box inside it?!

"Yes! That feels incredible... Spikey Wikey!" The plushie answered. Rarity's voice was so sweet and innocent. It was a little high-pitched, but still a perfect copy. Twilight couldn't believe her son would do such a thing. She had to leave right now and tell Rarity to the truth of this horrid action. But her body wouldn't leave that spot.

Her legs started to slide forward, the heat building inside her too much. The alicorn wanted this to end so badly and yet, she couldn't stop herself from falling onto her back. She creaked open the door more, getting a full view of Spike's face. He was so entranced with lust. There was no way he could see his own mother. And the plushie continued to cry out in such obviously fake pleasure.

"Oh yes! Don't stop! Spikey! Spikey!" Each pitch from the fake Rarity and growl from the real Spike pushed Twilight closer to doing the unthinkable. She wanted to scream and break the tension even if it meant total embarrassment. Yet, nothing could stop her hoof from reaching down over her pussy. Twilight bit her lip, trying to fight the urge to rub. But her son's actions were so fucking hot. He looked so much like a dragon that any stallion would be jealous. She just had to touch a little, and maybe then her brain could work properly.

Spike started to thrust faster, the fabric bulging harder and harder. It was so wrong and yet... The thought was so wrong, so twisted. Why would she be thinking about her own son?! Twilight bit her lip hard, trying to focus on anything else. None of it could save her from doing this horrid thing. She couldn't stop herself from giving in to the lust.

Twilight's hoof pushed through her folds. It was so hot and wet down there. Her juices were running down her leg and dripping onto the floor. The alicorn couldn't take it anymore, the sight of her son fucking a toy was driving her insane. She just needed a little release and then she could tell Spike off. It wouldn't be her fault, she was only touching herself to calm down.

The plushie continued to cry out.

"You feel so amazing, Spikey Wikey!"

And her hoof began to rub. Her walls clamped and released in motion as she tried to match her son's pace. Twilight's mind was lost as the image of Spike stood above her. She tried to picture anything else. Maybe her favorite guard, Flash, or that hot gardener outside, Timber. Heck, she would prefer the image of Rarity's ex, Thunderlane. Just not the visage of her own son thrusting inside her.

But no matter what she did, his image returned. She was starting to feel sick with herself. The moans from the plushie and the grunts from the dragon were starting to break her resolve. Her eyes went wide as she could see the knot growing and shrinking. Each thrust was pushing harder and faster, the bulge moving further up the plushie. Her own hoof was going crazy and she was getting wetter and wetter. Her mind could see it as clear as day. His incredible dragon cock plunging into her pussy and destroyed all her motherly pride.

"Don't stop! Spikey Wikey!"

The words hit her so hard, sending chills down her spine. Her body shook as the pleasure took over. She wanted that voice to keep talking, urging her Spikey to fucking her with no regard. Her hoof was becoming drenched, the wet squelching sounds filling the air. Her breathing became labored and her hips began to buck back. This was so wrong and yet, her brain didn't care.

"Keep going!" The plush cried out, "Please, Spikey Wikey! Don't stop!"

Her son did not disappoint. He growled and moaned louder, the sounds making Twilight's legs shake. She was reaching her limit and there was nothing stopping her from releasing her pent-up sexual desires. The voice was getting to sound so real, yet she had to keep thinking it was fake. The only sense of reality that defied the lustful hotness. Unsure if she was against the horrid actions any more or just plain jealous that Spike wasn't thinking of her in the same way she was utterly lost to him.

"I can't stop!" Spike growled out, "I'm gonna cum!"

The plushie was bouncing and wobbling wildly as her son thrusted his incredible dragon cock deeper and harder. Much to Twilight's shock, the final piece of strangeness peaked at the edge of her own lustful madness. The plushie replied with words Rarity would never say in public. "Yes, Spikey... fill my pussy with your seed."

Twilight's mind tried to question the sheer impossibility of that combo of words. However, all other thoughts faded away as she couldn't hold out much longer. She didn't want to cum while watching her own son. Her body was shaking and her head was spinning. She could feel the orgasm coming and there was nothing that could stop it.

"Yes, Spikey! Fill the plushie up!!"

And with that last comment, Twilight couldn't hold it any longer. Her eyes went white and her pussy clenched. She came so hard, the fluids flying up in the air and coating the floor right in from of the door. It was the best orgasm she ever felt in years. Her brain went numb and her body shook from the pleasure. Nothing could stop her from reaching this bliss.

All the confusion of the scene would have to wait. Her questions could never be answered... especially with Spike going right back to pumping after a few minutes. Seriously, he wasn't finished after all that. Dragons were so fucking hot, Twilight's answered herself as her hoof went back to work.

Miles away in the Boutique, up in Rarity's room, the unicorn mare laid back against her bed frame and breathed so heavily. A radio in one hoof, while she positioned an alicorn plushie right against her pussy. Hearing Spike grunt and growl on the other side of the speaker, she laughed and reached back down. This revealed a large stallion-shaped dildo on her plushie. Flicking it back on and watching it plunge back into her pussy.

"Spikey Wikey... You're so fucking hot!" Her eyes leered on the Twilight plushie, imagining it was the real Twilight thrusting into her. She pushed the mic away to ensure he didn't her say, "Wow... if only your mother was this whorish."

Author's Note

Yeah, just a quick fun, and disgusting incest fic. No need for a major story. Sorry, I couldn't bring you guys the final part of the Sleeping Dragon Trilogy. I hope this is a good stand in as this month has been a surprising amount of chaos. That other story will be postpone till August. Not because it's hard one to finish, no, rather I won't be posting any clops at all in July outside of stories still going on. This is to give me some proper breathing room before fall.
