The Ancient Chamber

It was another day in the Crystal Empire, another boring day in this boring kingdom. That was the mindset that Prince Frosty Heart held. Being raised in this arctic Empire, he had lived a somewhat sheltered life. Once, he and his family would visit his aunt, Princess Twilight, or even the other alicorn monarchs. But since the death of his father, Shining Armor, Princess Cadance, his mother, wouldn’t let her son out of anyone’s sight.

Waking up, Frosty only groaned, knowing that if he took too long to awaken, one of the Crystal Guards assigned to him would come knocking at his door. Sitting up, he did a little stretching before igniting his horn. At once, the door opened and a small force of maids came into the room. More personal attendants stationed by his mother, these mares were quick to help the stallion from his evening wear, and prepare him for the day.

After finishing getting dressed, Frosty left his room, where one of the Guards, Obsidian he thinks his name was, escorted him to the dining room. The massive, crystalline chamber, where grand banquets were once held, were nothing more than a long table, but only a chair on each end. Resting upon it were scores of hot and freshly prepared food. Sitting at the table, one of the servants, a unicorn stallion, approached the Prince, igniting his horn and displayed all the food.

“Good Morning your highness.” The servant greeted me respectfully. “Today’s breakfast consists of finely processed grains, fresh fruits cultivated and selected by our local gardens, and vegetables that will help a growing stallion such as yourself.”

“I’m nearly a hundred, I don’t think I’m gonna get any bigger anytime soon.” Frosty sighed, often irritated when others thought he was still a colt. But regardless, he looked across the table with a curious expression. “Where’s mother?”

“Regretfully, Princess Cadance is unable to join you for breakfast; as she has already eaten.” The servant explained, maintaining his professional composure. “She is busy with the recent archeological discovery under the Empire.”

“Oh? She’s still on about that.” Frosty asked, picking up a cup of his morning tea. “Well, whatever works for her.” Taking a sip, he sighed a little. “Well, I think I might as well pay her a visit. What’s my schedule today?”

“Oh course my prince.” The servant replied. “Right now, we have your breakfast. Following this, you have your magic tutor, history tutor, mathematics tutor, governmental tutor, and then a break for lunch. The chef is preparing something special, a vegetable pie and fruit tart for dessert. Then you have your fencing exercises, and finally your flight instructor has asked you to learn more about your weather control.”

“Then dinner, where the chef prepares something really fancy.” Frosty rolled his eyes, taking an annoyed sip of his tea. He couldn’t help but grumble. “Mother certainly is trying to keep me busy.”

“Well, tell the chef I’m skipping lunch. I’m going to pay my mother a visit.” Frosty commented, putting down his cup. “I know if I skip out on lessons again, I’ll get an earful, so I’ll just skip eating.”

“My Prince, if I may?” The servant commented, speaking a little nervously to Frosty. “With all due respect, you do require a full course of food. An alicorn such as yourself requires proper nourishment.”

“And I’ll have my nourishment.” Frosty commented, gesturing over to the food in front of him. “I’ll just eat a bigger breakfast.” Ignoring any other words the servant had, the alicorn began to eat. He was lucky Cadance wasn’t there to see him, as his table manners were very, very unbecoming of a member of the royal family.

Following his breakfast, and his various tutors, Frosty managed to find his time. Still feeling full from his morning gorging, he made his way to where he knew his mother would be, the archeology site. A little over a year ago, it was discovered that there was an ancient ruin under the Crystal Empire. From what little Frosty could learn, it was apparently far older than the current Empire. Though Cadance was keeping much of it a secret from her son, no doubt in some attempts at keeping him safe, Frosty had managed to get some of the workers to explain that his mother fears this could be from King Sombra’s reign.

Arriving at the site, Frosty doesn’t even bother to be subtle, waltzing into it without a care at who sees him. At his sides were more of the guards. The workers, upon seeing the Prince, quickly bow before him, and look at him curiously as he continues to make his way deeper and deeper into the site. It was strange. Like he understood, from his history lessons, that the Crystal Empire was formed from the native crystal mines being enhanced by magic, but for the caverns to go so deep, he couldn’t help but smirk with curiosity.

After several long minutes of walking, Frosty eventually arrived in the chamber that his mother was in. Now while the young prince was young by alicorn standards, he still looked the part of a well fit and healthy stallion. Princess Cadance, however, was much older, and had the body of a mare a fraction of her age. The only thing about her that was somewhat impossible for normal mares, were her features. She was tall, taller than the average mare, but shorter than her aunts, but her endowments were nearly rivaling them.

A slender neck that led down to a pair of large, supple breasts that were hugged by her attire. Even custom made, her royal regalia only clung to her alluring figure. One's eyes would only continue to follow her curves downwards, along her waist that shows not a scrap of pregnancy fat, and ended with her large, round ass that almost made faint sounds as she walked, and then her smooth looking legs. Frosty had lived long enough to know his mother was hot, but never really thought much of it, only what few whispers some servants didn’t know he had heard before.

“Frosty?! What are you doing here.” Cadance asked, gasping as she saw her son there. “You should be with your tutors, or taking or lessons, or something. Just not here. It’s dangerous.”

“Technically, this is my lunch break, and I’m choosing to skip the food to pay you a visit.” Frosty calmly replied, not wanting to give his mother the chance to go into her lectures on safety. “And since I’m here, what have your archeologists found out?” Cadance huffed a little, but it was too late to just send him away, and she did want to spend some time with her son.

“Fine, well, just stay by me.” Cadance replied, gesturing over to a table. On it, were number of drawn maps, charts, and various articles of pottery and crystal fragments, as well as other strange, broken relics. “We’ve managed to locate a chamber deeper into the ancient ruins. From what we have learned, is that it is preSombra in origins.”

“PreSombra? Then this means the chamber is from the time of Princess Amore?” Frosty asked, recalling his Crystal Empire history. “But why would it be this deep into the ground? We have to be almost a mile under.”

“Nearly, but there’s something else to it.” Cadance commented, pausing as if listening for a sound. “Can you hear it?” Frosty paused, closing his eyes to listen for whatever sound she was mentioning. After a moment, he heard a small hum.

“Sounds like…a hum…from the Crystal Heart.” Frosty commented, looking up to the ceiling. “Could the radiance of the Crystal Heart be a sphere and not a dome?”

“That’s what we were considering, but there still this chamber to investigate.” Cadance commented, tapping her finger on the map. “So, since you’re here, would you like to join me?”

“You want me to go in there, where there could be some danger?” Frosty chuckled, before composing himself. “Sure, I’d love to.”

“Don’t tempt me.” Cadance replied, somewhat giggling as she smiled to her son. “Since you were clever enough to find a time to come here, we might as well give it a look.” Her tone then shifted. “But only a look. If anything happens, you run. Understand?”

“Yeah, yeah, I understand.” Frosty chuckled, starting to walk ahead. “Let’s go.” Cadance sighed, following behind, while Crystal Guards followed them both.

Arriving at the room, both mother and son saw that unlike the rest of the ruins, this chamber was remarkably well maintained. Nothing was cracked or broken, with not even a bit of dirt or dust anywhere. Even as they walked into the room, there was a slight chill that ran down their spines. But this could just be the age of place, or an ancient magic maintaining it. The guards remained outside the chamber, guarding the only visible way in and out of it. Along the walls were numerous markings of ponies engaging in some sort of dance, feast, and other activities. But other than that, the walls held numerous ancient looking writings and carvings. They seemed to tell something, but it was seemingly difficult to decipher.

“Any idea what any of this means?” Cadance asked, looking at her son. “I’ve had scholars look through this chamber, but none of them can translate it, or even identify the language itself.”

“Hmm, maybe it was because they weren’t alicorns?” Frosty commented, taking a step forward. Reaching out with a hand, he gently rubbed along the markings. “I remember some of this, from those books Auntie Twilight sent me.”

“You can read this?” Cadance asked, looking at her son with amazement. “What does it say?”

“It’s not a language.” Frosty explained, igniting his horn a little. “These are spell sigils. Which means if the right spell configuration is made, then we can see what else the chamber is hiding.”

Igniting his horn some more, Frosty’s magic fully illuminated the room. But as the light of his spell touched at these sigils, they began to give off a faint, almost dim glow. The sigils swirled and moved, as if coming to life as they were being reshaped into what could be considered a language. Cadance watched in amazement, marveling at the magical talent her son had. And yet there was something else, like she felt a small longing for her son. Immediately, she shook away such a notion, and believed this was just pride in how good Frosty was.

“Got it!” Frosty commented, almost sweating as he had to concentrate on his spell. “Okay, I believe I have it now as a language.”

“Amazing! I wouldn’t never considered it to be hidden under such a spell.” Cadance commented, getting closer to Frosty to look. The stallion almost blushed as he started to notice how good his mother smelled. But he disregarded this feeling as he focused. “So, what does it say?”

“Well, from what it looks like.” Frosty commented, ignoring the previous feeling he just had. “I think it’s…it could be pre Unification of the Three Tribes. So if we take that into consideration…”

Frosty continued to adjust his spell, squirting and changing the stone script on the wall as if it were water until it was seemingly being translated. But as the letters, or what could be called letters, moved, they took new shapes. Rather than a script, they became images. Iconography of mares and stallions, naked and together. And within moments, the mares and stallions on the walls were in a wide variety of sex positions. Frosty and Cadance couldn’t help but blush a little as they watched this, but then a sudden sound caught their attention.

The door was closing. Both Frosty and Cadance gasped, eyes wide as they rushed over to the door. Numerous guards grabbed at it, trying in vain to hold it open, but it wasn’t enough. Just before mother and son could get to the door, and then it was closed; darkness enveloping them. In the dark, there were no sounds on the other side, even as the guards were slamming spells and magic at the door. Frosty and Cadance were doing the same, banging hands against the stone. But it was to no avail, the two alicorns were trapped.

“Fuck, fuck, fuck, fuck, fuck, fuck, fuck!” Cadance shouted, smashing her hands against the door, the room only being illuminated again as her magic pushed against the door, but it did nothing. “We’re trapped! Trapped!”

“I know, but mother, relax. Calm down.” Frosty commented, placing a hand on Cadance’s shoulder. “No doubt the guards are working hard to get the door open. All we can do now is wait.” And as he spoke, the room slowly illuminated, but with a reddish light as many of the carvings along the floor and ceiling started to glow. “See, this must be something I triggered with my spell. So all we have to do is wait.”

“Can’t we just try the spell again?” Cadance asked, still visibly panicking. “Surely there has to be something?”

“Possibly, but it’s probably not a risk we should take.” Frosty commented, gesturing to the imagery carved in the wall. “I’m willing to guess this was a chamber for ritual sex.” He then pointed over to various corners of the room. “And those sigils are powerful anti-magic wards. Most likely to prevent scrying or teleportation. So we’re stuck here until the guards get the door open from the other side.”

“You’re being…a little too calm about this.” Cadance commented, groaning in frustration. “How can you stay calm?!”

“Well, it’s like Auntie Twilight told me about magical traps and chambers. It’s to stay calm, and be patient.” Frosty explained, walking over to one side of the room. “For now, we should wait. You found this door closed when you first found it right? So surely there’s a way to open it from the other side.”

“You’re right, you’re right.” Cadance sighed, trying to compose herself. Walking over to her son, she sat besides him. “So, since we’re not going anywhere. Why don’t we talk about how your studies have been.” It wasn’t exactly the ideal situation for him to be able to talk to his mother, but Frosty took what he could.

It was impossible to tell just how long they’ve been in this chamber. The reddish light was the only illumination Frosty and Cadance had. Still, it was good for him to get a chance to talk to his mother for such an extended period of time. Before today, the only time he had to even see her, let alone talk, was during meals. Everything else was whatever message a servant told him, or some letter. Despite being trapped in some ancient chamber, Frosty was happy that he was at least with his mother.

That said, the mare beside him was starting to sweat. Some were no doubt worried and nervous, but her body was certainly getting hotter. At first, Cadance ignored it, focusing more on her conversation with Frosty. He had grown into such a fine young stallion. He was fit, strong, and handsome. For a moment, she could see Shining Armor in their son, and it made her heart flutter a little. Her face was going red, but she only believed this to be the growing heat in her body.

“Are you okay?” Frosty asked, now starting to sweat as well. “Is it just me, or is this room getting hotter?”

“It is.” Cadance replied, looking around the room. “I don’t think the heat is meant to kill us, but if we don’t do something, we’re going to overheat anyways.” As she said this, she started to fidget with her clothes.

Frosty’s eyes widened in shock as he saw his mother start to strip from her clothes. Even with the underwear she wore under the dress, it still showed off just how huge her tits were. The young alicorn couldn’t look away, feeling as his body was getting even hotter. By the time she was down to her underwear, Cadance was still panting more and more. It was like disrobing was making her body become hotter and hotter.

“Frosty, I know it’s not the best, but you should get out of those clothes too.” Cadance suggested, worrying that her son must be going under even more heat than she was. “It’s just so we don’t overheat.” She gently rubbed his head. “Besides, I’m your mother. Whatever you have, I’ve seen it before.” This surprisingly put the stallion at enough ease to start striping.

Frosty, despite being small for an alicorn, was still a very well built stallion. His muscular frame was impressive, nearly surpassing the strong figure of his late father. Cadance couldn’t help but blush a little, and she couldn’t take her eyes off her son as Frosty took off the rest of his clothes, until all that remained was his underwear. That is when Cadance saw that her son was gifted, especially gifted as his bulge seemed to surpass Shining’s impressive size.

Now, the two of them sat there, both down to their underwear in this chamber. But it still wasn’t enough. If anything, the two of them were feeling even hotter than before. Cadance and Frosty looked at each other. And while words were not exchanged, they both knew what had to happen. To avoid overheating, the two of them were going to need to get fully naked. They hesitated, but the way they were sweating more and more was too much. It had to be done.

Cadance was first again, slowly taking off her underwear. Frosty’s eyes widened in shock as he got a full view of his mother’s bare tits. What was practically a national treasure, the alicorn’s chest was quite endowed. Plump and soft looking nipples, all resting comfortably over her slender waist. But then, her panties revealed her delicate looking pussy, all along her perfectly rounded ass. The mare was a living sex goddess, and while he knew this, seeing his mother’s figure all his life, Frosty struggled to maintain his composure.

“Come on, Frosty.” Cadance commented, trying her best not to stare directly at her son as she blushed. “We can’t overheat here.” Her son nervously nodded as he slowly pulled down his underwear.

Cadance’s eyes widened a little as well when she saw her son’s cock, or rather his half erect size. The stallion was a gift, very gifted. Already sporting something that easily rivaled his late father’s. The mare couldn’t help but swallow nervously, the heat in her body only growing hotter and hotter. Even at this distance, the two of them picked up a new scent. It was a mix of musk and sweetness; the arousal of the other. Though neither would say anything about it, their bodies were getting turned on.

“We…we need to do something about this chamber.” Cadance commented aloud, standing up as she didn’t want to keep sneaking glances at her son’s limp cock. “I’ll…I’ll look over here and see what I can find.”

Cadance walked over to a nearby wall, Frosty’s eyes following her a little. Her curves were so hypnotic, and the way they bounced was making it impossible for him to keep his cock soft. Trying to distract himself, he looked somewhere, anywhere that wasn’t his mother’s alluring, goddess body. This brought his attention to some of the sigils he had triggered. Squinting his eyes a little, he tilted his head and saw that there was a deeper meaning to the markings.

‘These icons…this isn’t just a ritual chamber.’ Frosty thought to himself, silently mouthing his thoughts a little. ‘It’s a sex chamber. So this heat…it’s arousal.’ Glancing over to the door, his eyes widened as a realization dawned on him. ‘Which means, the only way out is to…’

This was an impossible choice. Even if he was correct, and the only way to open the door is to proceed with the chamber’s rituals, Frosty would have to fuck his own mother. There had to be some other way, there just had to be. And yet, the more he looked at his mother with a worried expression, the harder it was for him to think of anything but her alluring body. It was becoming too much for him. His cock was nearly at full arousal, and it was already leaking out little bits of precum. That was, until as she looked over the wall, Cadance bent over.

That was it, this was what pushed the stallion’s mind over the edge. Her pussy, this sweet, sexy snatch was too much for Frosty to handle. Swallowing the last of his doubts and worries, he slowly stood up. His cock wasn’t hard, it was throbbing, massive and oozing out precum. His eyes were fixed on his mother’s ass, almost feeling the softness of it against his hands. Frosty trembled a little, feeling as a more instinctive, animalistic aspect was spreading through his mind. Was this part of the ritual? Was he just finally letting it all go?

“There has to be something we can do.” Cadance commented aloud, unaware of her son drawing closer to her. “Frosty, what do you think we can do?”

“I know a way.” Frosty replied, walking closer and closer to his mother. “It’ll be tough, but I’m sure we can do it.” He licked his lips, he was just about to touch her, to reach out and claim the unsuspecting mare.

“Well, whatever it is, anything is better than staying here.” Cadance replied, unaware of the almost sinister, lustful eyes behind her. “So, what did you have in min-aahh?!”

Frosty sprang on his mother, grabbing at her hips and pulling her closer. As he did, his fat cock slipped between her smooth, warm thighs. Cadance arched herself back in instinct, which caused her large best to bounce. Looking back, she saw her son, Frosty’s eyes were almost gleaming with an emotion she was all too familiar with. This was love, but deeper, rougher, and more raw. A loving lust, one that was sending ripples of heat throughout her body. But then, she noticed his fat, throbbing cock between her legs.

Cadance tried to speak, but as soon as a small coo nearly left her lips, she covered her mouth. This wasn’t happening, this couldn’t be happening, this shouldn’t be happening; and yet it was. Frosty’s cock wasn’t just shoved between her thighs, but the length of the shaft was slowly rubbing along her soft pussy lips. Cadance shivered, feeling as her aching embrace was getting wetter and wetter, and the smell of Frosty’s musk was numbing at the mare’s senses.

“F-Frosty…can we…can we talk about this?” Cadance asked, nervously looking back at her son. “Like…m-maybe…just maybe…we could…um…” Her words were trailing off as she had to repeatedly muffle herself as her son’s cock was making her moan a little as he rubbed.

Frosty’s hands were doing more than just hold at Cadance’s waist, he was groping her ass. The milf mare’s flank was so soft, like a big, fat pillow of solid pudding. The stallion’s fingers nearly sank into them as he groped and squeezed hard on this fat ass. His cock throbbed some more, leaking out more precum, and the moisture of his mother’s pussy on his shaft was making him shiver with delight. She was getting aroused, she had to be. Her body was craving this just as much as he was.

“F-Frosty…Frosty…think about…think about what you’re do-” Cadance tried to plead with her son, to stop him from making a major mistake. But he wasn’t listening. Moving his hips a little, he slid his cock between his mother’s thighs. “There…t-t-t-there’s still time to…time to…” Her words were trailing as she struggled to hold in her moans.

Frosty’s cock throbbed madly between Cadance’s thighs, oozing out his rich, potent precum; letting it drip on the ground. The mare could smell the sweating arousal of her son, a sensation she hadn’t felt in decades. Her mind resisted, even though it was weakening, but her body was longing for this touch. She missed having a strong, hung, and needy stallion between her legs. Her mind tried to hold back, she wanted to fight back against this, but Frosty’s hands, the way he was grinding between her thighs, it was all too much.

“If…if you’re…in pain…” Cadance suggested, swallowing nervously as she looked down at this cock. “I…I…I-I-I-I-I can help you.” Frosty’s grip loosened a little bit, letting his mother walk forward.

Turning to face her son, Cadance could see he was desperate for this, driven by an urge to fuck. Not only that, but it looked so painful, her precious son was in so much pain and anguish. Her motherly heart nearly skipped a beat as she looked at him. Frosty’s cock throbbed, his eyes trembled, and his body shivered. He was in need of this, he wasn’t able to handle these lustful urges, and it pained the mare to see him like this. Looking over to the door, she was confident it would be some more time before anyone would arrive. Surely, there was no harm in helping.

“I’ll…I’ll help you relieve some tension.” Cadance commented, trying her best to remain composed, but it was hard as her own body was incredibly aroused by all of this. “But…if we do this, we can never tell anyone.” She hesitated for a moment, but had to commit to her resolve.

Slowly, she got on her knees, now fully facing this cock. Frosty watched as his mother was staring at his dick, the way it was pulsing, leaking, and throbbing. Cadance swallowed nervously, not sure how she should go about. It had been many years since she’s done this, and it wasn’t like she lost all her experience. But the fact it was her son’s cock that was making her body feel so hot that was sending a sense of shame, and yet this shame felt so arousing. She shook her head, trying to forget those thoughts, she had to get her son off, or who knows what he’d do.

Reaching out, she slowly started stroking along her son’s cock. She felt the way it was throbbing to her touch. Her fingers naturally danced along the length, making the alicorn wince and moan. Cadance hesitated for a moment, was she hurting him? No, no, that wasn’t it, he was still letting out those sounds of pleasure. He was feeling good, she was slowly stroking his cock and making him feel good. She swallowed nervously, she felt her own body still so hot, so needy. Her pussy ached to be touched again, even for a little bit again.

‘I shouldn’t do this. This isn’t right.’ Cadance thought to herself, shivering as the smell of Frosty’s arousal was getting stronger and stronger. ‘Frosty…you’ve grown up into such a big stallion.’ She didn’t want to think about these things, but her mind seemed to only wander and ramble. ‘You’re…you’re just like your father. Shining used to make the same noise when I-'' She gasped as she shook her head. ‘No, no, I shouldn’t be thinking this. I’m not doing this because I want to. We need to do this…to escape. Yes, yes, that’s it. To escape! I’m just jerking off my son because I want to or anything.’

The more she denied this, the more her senses were being afflicted by the scent of Frosty’s masculine size. It was numbing her mind, making it harder and harder to think. Her face was a scarlet blush as the stallion was huffing faster and faster. His cock throbbed in her grip, which was getting faster and faster. Was he about to cum? Surely, he had to be. Cadance may have been without sex for years, but she still knew how to jerk off a fat cock. Moving faster and faster, she could tell Frosty could cum soon, but he needed a small push. That is when she noticed his balls.

“Just…just a little more…” Cadance cooed, trying to speak her son into his climax. Reaching with her free hand, she started to gently heave and massage Frosty’s balls. “It’s okay Frosty. You can do it. Cum for me. Cum for mommy.” Her words were enough, the stallion gasped as he felt his cock swell before finally releasing in orgasm.

Frosty’s climax was big, above what a normal stallion should be able to do. Spraying out, his hot spunk splattered against Cadance’s face. By instinct, or just not wanting to mess up her face, the mare opened her mouth, taking the length in her mouth. Her son reached down, grabbing the back of her head, pulling her to deepthroat the full size of his girth. Cadance’s eyes went wide as she felt her throat bulging from her son’s cock.

She wasn’t choking. As much as Frosty was pumping into her belly, it would take a lot more than this amount of spunk to make Cadance gag. But the strength of this orgasm was certainly impressive. Frosty was such a healthy stallion, and the flavor of his cum was heating up his mother’s insides. Her pussy was soaked, dripping her sweet nectar onto the floor. Shivers ran down her spine, and her tongue rolled around the length of her son’s cock.

Holding Cadance’s head in place until he finished his last few spurts of cum, Frosty eventually released his mother from his grip. Cadance slowly pulled herself off, making sure to adequately clean off her son’s cock before slowly standing up. Her legs wobbled a little, which made her tits bounce a little. Frosty was huffing, recovering from his orgasm, having it drain more out of him than he thought. Cadance was hoping that this was enough and turned to look back to the door.

“Okay, I hope that was enough for you.” Cadance commented, still feeling a little lightheaded, but didn’t notice that while tired, Frosty wasn’t finished, and his cock was getting hard again. “Now, all we have to do is-” Her body tensed up as soon as she felt Frosty’s hands against her ass again. “F-Frosty…i-i-i-isn’t….isn’t what I did…e-e-enough?” Her son only answered by pushing his cockhead against her soaked pussy lips.

Before Cadance could say another word, Frosty pushed forward. His mother was so tight, only getting the cockhead in, causing her to let out a low moan. She wanted to fight back, but it was like this dick was just draining her of any resistance and strength. After a moment’s pause, Frosty started to delve his dick deeper and deeper into his mother. It was amazing, tight at first, Cadance’s moist embrace was taking in her son like the two were made for each other. She moaned a little more as Frosty’s cock was slowly working his way to bottom out inside her.

Cadance felt as her strength was being slowly fucked out of her, Frosty’s length was buried so deep, and the way her pussy was being stretched out from it was making it harder and harder to think. She didn’t want to admit it, but the pleasure was immense. She hadn’t felt this good in years, and even the shame of getting turned on by her son fucking her was only adding to the sensation of growing ecstasy. Her mind conflicted with her body, but any attempts to speak only let out small moans.

Frosty’s cock was good, a natural savant at fucking his mother’s perfectly fuckable hole. But he heavily lacked her experience. He wasn’t going to last long. Humping faster and faster, the alicorn was getting himself ready to cum. Cadance could feel it, and while her mind was screaming at her to move, to push him off, or anything, her body was numb, frozen in place as if her pussy was eagerly awaiting the climax to come. Opening her mouth, a whorish moan slipped out, which drove Frosty into a wild fuck frenzy.

Faster and faster, the alicorn was hammering his dick in his mother. His dick throbbed madly as his balls were tightening against his body. Letting out small, almost primal sounds as he hissed through clenched teeth. After several more long moments of passionate fucking, Frosty shivered as he slammed his full length in the mare’s soft embrace. Cadance gasped as she felt not just the full length of Frosty’s cock stretching her, but it was nearly pushed past her cervix, letting him release his hot, thick, and heavy load in her womb.

As soon as Frosty came in Cadance’s pussy, both alicorns felt their bodies get hot; hotter than before, and on the verge of collapse. Her son didn’t have the endurance to hold on, and collapsed backwards, his cock slipping out of his mother’s pussy. Cadance’s body trembled as her legs wobbled, and her pussy dripped out the potent release still warm in her womb. Gasping and panting, she looked at her son, her eyes caught the flickering light that started to erupt around the chamber.

The sigils were glowing, perhaps this was part of whatever this chamber demanded of them. As well as this, the room was not feeling as hot. If anything, it seemed to be getting a little colder. A small number of grinding sounds were slowly being heard. Cadance could only guess what was happening, but for now, she conjured what magic she could, cleaning herself and Frosty’s bodies. Afterwards, she dressed herself back up, but needed to be careful to get her son dressed again. No sooner had they finished being dressed again, her ears perked at the sound of the door opening.

On the other side, guards, researchers, and medics gathered, rushing in to look the royal family over. Cadance only let out a small sigh, counting her fortunes that none of them caught her and her son naked in this chamber. Frosty was fine, a little tired, but wasn’t in any danger. Just wanting to leave this chamber, Cadance lifted her son up, carrying him from this room. None of the guards or medics stopped her, and she chose to ignore the numerous questions that the researchers had. Answers could come later. For now, she wanted to put her son to bed, and take a long bath.

Several long hours passed since the events in the chamber, Frosty rested on his bed while Cadance had to handle some business. Since waking, the prince had a vivid memory of what happened in that chamber, and while the guilt was eating him up, his body couldn’t forget the warm softness of his mother’s pussy. Whether Cadance felt the same, he didn’t know, and it ached at his heart whenever he thought of it. Currently, he was taking a bath, resting comfortably in the royal bathhouse. Thankfully, he was the only one there. But his mind just couldn’t forget what he and his mother did.

“Mother…” Frosty murmured weakly to himself, laying his head back against the rim of the massive bathing pool. His cock was hard, throbbing almost painfully as his mind and body were almost imagining Cadance working his dick. But not of him forcing himself on her, but of her skillfully working her beautiful body on his shaft. “I…I can’t forget…what I did…”

While Frosty was in and out of his fantasies, Cadance, who was feeling equally guilty for avoiding her son like this, was making her way to the bathhouse as well. Her mind and body equally couldn’t forget what happened in that chamber. It was sheer fortune she was able to apply her magic to prevent pregnancy. She had to speak to Frosty, she couldn’t avoid him forever, and she needed to talk about this before anything strange could be bred from these feelings. But first, she needed a bath, something to help her fully clear her head as she planned out her coming discussion with her son.

Arriving at the bathhouse, Cadance didn’t even notice that Frosty’s things were already put in a nearby basket. Her mind was in such a mess, she couldn’t see anything but the goal of taking a relaxing bath. But when she finally walked into the open chamber that made up the bathhouse, her eyes widened as she realized she wasn’t alone. Frosty was here, in the last place she wanted to find him in, especially after what happened in the chamber. She had just barely let out a quiet gasp, when Frosty saw her.

Frosty’s cock was so big, Cadance’s body reacted to just the sight of it. Swallowing nervously, she couldn’t help but gawk and stare in awe at her son’s size. Such a thick, juicy, meaty looking girth that his strong hands were eagerly stroking. Her body trembled a little, her nipples hardened and her pussy was getting wet from it. She wanted to look away, but just couldn’t. Her softness desired to be teased, to be touched, and to be pleasured again. She didn’t want this, and yet she couldn’t turn away, and her body felt the phantom sensation of her son’s cock inside her.

“M-mum?!” Frosty gasped, speaking timidly as he could barely look directly at her. “C-could…could you please give me a moment. I’m almost done.”

“There’s no need.” Cadance replied, looking at her son with panting eyes. Trying to compose herself, she walked into the hot waters, sinking up to her shoulders, leaning against the edge of the baths. “We’ve…we’ve done worse.”

“Y-yeah…” Frosty blushed, looking away as he fidgeted nervously. “H-how have you been?”

“Probably the same as you.” Cadance replied, trying to maintain her composure, but unable to look at her son. “Just…just coming to terms what happened.” She sighed a little, feeling so nervous as she slowly rubbed her thighs together.

“I…I didn’t hate it.” Frosty weakly replied, blushing sheepishly as he spoke. “I…I don’t know what came over me, but I was…it felt so good.”

“F-Frosty…what happened down there…what we did…” Cadance tried to explain herself, but her words were only getting caught in her throat. “I…okay, yes, it did feel good. But there are ways about these things. What we did…it felt good, it felt really good. In fact, I haven’t felt so good in years.” Her emotions were letting her true feelings coming out as she just couldn’t hold it in. “It’s just…how it all happened, I just…I just don’t think we should-”

Her words were cut off as Frosty approached her, splashing the water as he moved closer to her. Cadance could see it in his eyes. Determination and longing. As the alicorn of love, she could always see the strength one has in their love for another. And for her son, it was blazing all around him, like his body was enveloped in a flaming aura of want and passion. She trembled a little, knowing what he was most likely about to do, and she couldn’t allow it to happen again, she just couldn’t.

“F-Frosty…listen to me…please…we can’t do this…” Cadance said, trying to sway her son away from his actions, but they were to no avail. He was only getting closer. Her body was stuck in place, and her lips quivered nervously. “W-w-w-w-we can’t…we…we…we…Frosty…I’m telling you, we-” Her words were cut off as Frosty’s lips pressed against her.

At once, her body erupted in climax. Just being forcibly kissed by her son was enough to push her over the edge. It felt so good, she couldn’t deny this feeling. Her mind resisted, hating every second of being at her son’s mercy. But her body, her body was so limp and soft, completely submitting to the pleasure that was going to be renewed throughout her being. Frosty wasn’t driven by the same magic that afflicted him in the chamber, but he couldn’t hold himself back after hearing that his mother didn’t hate him.

‘I can’t let this happen! I have to stop this!’ Cadance’s mind screamed at her, feeling as her son’s tongue was slipping into her mouth. Her body let out a soft moan as her body got hotter. ‘I…I…I just…I’ll…I can’t hurt my son. I’ll let him just let it all out.” Though she wasn’t fully into it, Cadance accepted the situation.

While Cadance confronted her son, the researchers were hard at work studying the various sigils and runes within the chamber. The door had remained open, but were reinforced with various stoppers and buttresses to prevent it from closing again. There was so much to learn about this chamber, and yet Cadance had yet to tell them anything. Rather than wait for the Princess to detail them, the researchers were trying to decipher as much as they could.

Suddenly, some of the sigils started to glow. Quickly, the researchers were preparing to flee the chamber, but the door made no attempt to close. Curious, they monitored the runes, writing down as much as they could about this strange circumstance. Their horns ignited, trying to cast all manner of analysis spells on the sigils, feverishly writing as much as they could, but no magic revealed anything. But then, another sigil ignited, letting off a warm sensation that almost kissed the researchers. Whatever was happening, they were excited to write it down.

“Frosty…Frosty…” Cadance moaned, bent over the edge of the baths. Water splashed loudly as her son was hammering his cock in and out of her pussy. The cum of his previous orgasm leaked out of her pussy. “Don’t…don’t stop…just let…let it out…” Her moans echoed out in the room.

Frosty couldn’t think, nothing in his mind existed but the overwhelming desire to fuck his mum. The Prince and Princess moaned out, feeling as their passions only swelled and swelled. Her pussy was wrapping so warm and tightly around his cock, while his dick rubbed and pleasured every inch of her sensitive insides. Any thoughts of defiance or resistance meant nothing to the mare. All she wanted was to feel her son fucking her. The taboo of mother and son fucking was building up the pleasure that was getting the two of them to their next orgasm.

Pumping faster and faster, Frosty felt as he was about to cum again. Cadance’s pussy squeezed tightly, not wanting to let her son’s dick go. The stallion huffed and groaned, humping harder and deeper. His cockhead was passionately kissing at his mother’s cervix as she was cumming over and over again on his shaft. She couldn’t get enough of it, she couldn’t think of anything but having Frosty’s cock in her. She missed this feeling, the way her insides were being stretched and filled, how her large tits bounced with each thrust, and wet slapping sound as his hips met with her ass.

“Frosty…Frosty…again…cum in me again…” Cadance moaned whorishly, fully submitting to the pleasure. “Fuck mummy, fuck her like she’s yours. Give mommy…your hot cum…” Her words were enough to push the stallion over the edge. Frosty moaned out, gasping as he slammed his full length back into her.

At once, another hot and thick load of cum pumped in her pussy. Cadance’s womb was savoring the sweet and warm feeling of her son’s spunk flooding in her most precious place. Her horn gave off weak sparks as she was quivering in her own climax. Frosty held himself in place, his cum soaking his mum’s insides as the two of them panted in the afterglow of their pleasure. But they weren’t finished. Cadance’s pussy was still squeezing along her son’s length, milking it for more, while Frosy’s cock was still throbbing hard.

“Frosty…come here…” Cadance weakly moved forward, pulling her son out of her pussy. Turning around slowly, she lowered herself in the tub. “Let me clean you off.” Opening her mouth, she took in Frosty’s cock, bobbing her throat over it like a heat stricken whore.

“What is this?” One researcher asked aloud, writing down more and more as other sigils were igniting. “Quick, quick, another one is illuminating!”

The researchers were in a frenzy, rushing in and out of the chamber. Papers and scrolls were in their hands, books floated behind them, chalk and charcoal were being rubbed against the papers to get imprints. They wouldn’t make any headway in understanding the meaning, but there had to be something about it. There were dozens of sigils, but only some were glowing, and almost none of them were close to each other to reveal any noticeable pattern. To them, it looked so random, but there had to be something.

“Quickly, before it fades, get an etching!” Another researcher shouted, getting his papers to many of the sigils. “We can’t lose this progress. Label in what order they glowed. I want times on how long between them did they begin to activate!”

The researchers rushed as fast as they could, not wanting to lose a second of it. They needed to mark, draw, etch, and label any and everything they could. They didn’t even think of finding Cadance over this. They were just so focused on the research. But then another sigil began to glow. Quickly that one was marked and labeled, as well as a time between them. It was impossible at first to see any pattern. The locations seemed random, and the amount of time between igniting also varied.

Cadance was laying on her back on the smooth tiles of the bathhouse floor. Her son was hammering his hips hard against her pussy. His cock was rubbing faster and faster. She was cumming from the feeling, to be held like this, and yet her son was becoming more and more assertive. It was like he was almost possessed by the insatiable desire to fuck and breed. What little sanity remained in her mind was trying to get her to magically prevent pregnancy, but magic was so difficult to focus on throughout all the pleasure being fucked into her.

“Frosty, Frosty, keep going.” Cadance moaned, reaching up to gently pet her son’s cheek. “I love you, son. You don’t need to hold back.” Her eyes sparkled with a blurring of love, passion, love, and compassion. “Show mummy how much you love her-aahh!”

Frosty grabbed at Cadance’s legs, lifting them as he started pushing even harder. Cadance hadn’t fucked in a long time, but she knew what her son was doing. This wasn’t a loving missionary position, he was pushing to fuck his mother in a hard and deep mating press. She arched her head back as she moaned as she felt Frosty’s cock pushing so much deeper inside her. Her insides eagerly accepted her son’s cock, taking in every throbbing inch of it.

Frosty huffed, groaning out in pleasure, feeling himself getting closer and closer to his next orgasm. The previous releases that were still hot in Cadance’s pussy were sloshing and helping the dick slip in and out of the mare’s pussy. The two were trembling, his body tensed up a little bit as he was about to cum again. Cadance reached up, grabbing at her legs to help pull them back and let Frosty fuck even deeper.

The stallion’s cockhead was partially poking through the cervix, ready to deposit the next hot and pontent load in her fertile womb. Her belly tingled, tits madly bounced as her nipples trembled. She was moaning, panting her hot breath as it kissed against the stallion’s neck. His eyes narrowed as if he were a predator ready to strike. Pushing his body over the mare’s, he hammered faster and faster, bottoming out his length in the softness of the mare’s embrace.

“Frosty, Frosty, Frosty, Frosty…don’t stop…keep going…” Cadance moaned, feeling her eyes almost rolling back as she trembled at her son’s savage fucking. “Inside, inside, cum inside me…I want it…” Frosty couldn’t hold himself anymore, and slammed himself into his mother’s pussy.

His next orgasm flooded deeply in her womb. Her ovaries were being saturated in his potent seed. Part of her was trying to get her to cast her spell, to prevent a possible pregnancy. And yet the rest of her being ignored it, only wanting the pleasure that she craved. Frosty had already come in her a few times now, and yet his dick wasn’t settling down. She wanted more, she needed to feel her son deep inside her.

As if feeling her mother’s desires, Frosty shifted his hands, lowering them as he groped at Cadance’s ass. The mare gasped as she felt the strong groping of her son’s hands against her flank. Her body trembled, still sensitive in the afterglow of her previous orgasm, but it wasn’t enough for Frosty. Pulling at her, he stumbled himself backwards, off the floor. Showing remarkable strength, he managed to lift Cadance up. Her body weight pushed down on his cock, making her gasp. To support herself, she reached her arms up and under Frosty’s arm.

Seeing his mother’s moaning and sexy face so close to him, Frosty couldn’t hold back his feelings. While fucking upwards into Cadance’s pussy, he pulled her head closer to his, causing them to kiss. As soon as their lips met, the two of them immediately started to make out. Their mouths moaned into the other, their tongues rubbed and danced as the stallion humped upwards faster and faster. Her pussy was tightening around his length, the cum inside her womb was eagerly soaking every inch of her precious place.

Cadance’s mind was melting, never wanting this feeling to end. All that mattered was how good this felt. She wanted nothing more than to have her son’s cock claim her as his. The way he strongly squeezed at her fat ass, making her huge tits bounce and rub against his muscular chest, and how passionately he was kissing her. He was so devoted to bringing out as much pleasure as possible. She longed to always have him inside her, she wanted him to take her whenever he wanted.

Frosty’s cock throbbed, still not having the endurance to last long against his mother’s perfectly fuckable pussy. It was too heavenly, and all he could do was release himself again and again. It would take a long time before his dick could settle down, but he was going to cum in his mother over and over again. His mind was void anything but the craving instincts to fuck and breed. Kissing more passionately, Frosty felt as if he was about to cum again. Trying to keep his mother held up, while continuing to hammer in her pussy, the stallion and mare moaned in each other’s mouth.

Frosty’s next heavy load was pushed and pumped in Cadance’s pussy. She gasped a breathless moan of orgasmic bliss. She loved this feeling, every resistance was fucked away, and all she longed for was to let this passion continue until the two of them would collapse. This seemed to somewhat be the case as Frosty’s legs were getting weak. The mare felt as if the stallion was losing his grip and balance. Thankfully, he was able to turn himself around, falling back onto the floor. Cadance landed on him, feeling his cock slam deep into her pussy again.

“Frosty!” Cadance screamed in another orgasm, looking at him with lustful eyes. Pushing herself over him, she made out with her son again as she moaned and wiggled her ass over this cock. “Let mommy show you how much she loves you.”

Lifting herself up, the mare carefully turned herself around. She did so to keep the cock buried inside her, not wanting to give it up for any reason. Now facing away from Frosty, she started to bounce up and down the shaft, riding it. The stallion only watched as his milf mum’s huge, soft ass bounced and pressed against him with each motion. But he was too driven by lust to stay lying down. Something in him almost commanding his every moment to be spent fucking his mother.

Reaching up, he grabbed at her arms, pulling her back. This caused her to collapse backwards, laying her back against his chest. The mare cooed, curious as to what Frosty was going to do. Her answer came as her son’s hands then reached up and started to brutally grope and tug at her tits. Her touch starved breasts were so sensitive, with her nipples making her nearly spray out her hot nectar as he teased and twisted them. Cadanced moaned her sultry sounds, letting Frosty start thrusting upwards and back deep into her as his hands squeezed at her chest.

“So rough…so tough…keep going…don’t stop…” Cadance moaned, her eyes becoming half open and twitching as she was lost in pleasure. “Fuck mummy…play with her tits…make mummy your whore…”

Frosty couldn’t stop himself, he had to keep fucking. Humping upwards, he made her soft curves bounce as his hips smashed into the mare’s flank. The two of them panted and moaned, feeling nothing but the sweet joys of the pleasures. The water seemed to ripple as the floor shook slightly from the hard, deep thrusts. Cadance moaned, rolling her eyes back as she was taking the hard size of Frosty’s cock. But he wasn’t going to settle back. After a short while, he was able to get some strength back.

Now laying on their side, Frosty was tugging and playing with one of Cadance’s tits, while the other bounced freely as he was fucking into her. The mare moaned out, feeling herself getting through another strong orgasm. Her mind was like a mush, and her passions were the only thing keeping her from passing out. Seeing his mother’s beautiful breast bouncing, Frosty only swallowed nervously before opening his mouth.

At once, he cupped his mouth over Cadance’s nipple, licking along it as he suckled the whole lucious areola. The mare moaned out, feeling as her tits were being teased, and tight pussy was stretching eagerly to take in her son’s cock. It was so good, her pussy was spasming out her soaked climax as passions melted away any sense of reason. Frosty only rubbed, suckled, and fucked, his hot breath coming out of his nostrils as he sucked on Cadance’s tits as if he was trying to drink her milk.

“F-Frosty…don’t suck…ahh…don’t suck that hard…” Cadance moaned, just barely holding on as she was just barely hanging onto herself. “Mommy…mommy doesn’t have any…any milk…” Her words seemed to trigger something in the stallion’s head. Whether thought or instinct, he huffed, sucking hard before pulled his mouth off with an audible pop.

Cadance gasped out, arching her head back in the pleasure of her sensitive nipple being freed of the warm, wet mouth. Frosty called on what strength remained, his horn sparking on his body was straining but determined to do this. Tilting Cadance’s body back up, he lifted her a little. But unlike before, he walked slowly and carefully back towards the bathhouse’s pool. Thanks to the still warm waters, it provided the support he needed. Slipping his hands fully under his mother’s thighs, he hoisted her legs up and then groped at her fat tits again.

Cadance moaned, her tongue hung out of her mouth as she was being fucked even deeper. Now that her weight on his legs wasn’t as much of a burden, he only focused all his strength into fucking. His cock hammered hard and deep, making her ass splash as it smacked down against the surface of the water whenever he dropped her on his dick. His hands squeezed and groped tighter, tugging at her nipples as if he was trying to milk her.

Both alicorns couldn’t say anything else, only moan and groan in their carnal cravings. The stallion was going to cum, he was going to let out his biggest load in his mother, while the mare was on the verge of collapse, all it would take would be another heavy orgasm in her pussy to put her over the edge. Shame still washed in the back of her mind, but she knew it was too late. There was no going back, and all she wanted now above all things, was to feel Frosty’s next orgasm flooding her womb. She wanted him to fuck the place he was born full of his hot seed.

Close, Frosty and Cadance were getting so close. The two of them could feel as their hot releases were coming. Pulling back as he lifted his mother, the stallion pulled her down by her breasts, while slamming his full length into his mother’s pussy. Her cervix gave way for this masculine dick, letting him push hard against her womb’s inner walls as he deposited his biggest, hottest, thickest, and heaviest load of virile cum. Her fertile insides were flooded, her ovaries saturated as she felt a warm shiver run up her spine. But eventually, Frosty’s body couldn’t hold on anymore, collapsing the both of them in the water with a loud splash.

That was it, the two of them had fucked, again. But not just fucked. Cadance and Frosty had engaged in a passionate exploration of the other. It was like nothing else outside the bathhouse existed, and the two of them were in their own little world, even for the time they had together. Their bodies had been joined, and there was no way either would go on normally without the other. Her pussy and his cock were in such harmony, like they were both meant to fuck like passionate lovers.

“Frosty…are you…are you okay?” Cadance asked, cooing as she seemed to catch some of her breath. Frosty only nodded, giving out weakened moans. “Good, good…cause I’m sorry, but…but I’m still so horny.” Her eyes fluttered as she looked at him so seductively. “Would it be okay…if you sleep in my bed tonight?” Frosty’s cock only throbbed in agreement, making her giggle and moan.

The following day, Frosty and Cadance, having had a long night fucking in so many positions, the bed’s matress was halfway off the bedframe. But when the morning finally came, the two of them were still so tired. The long night of sex, the possibly gallons of cum that he had fucked into his mother, and how her mind was marked so thick with her son’s hot scent. It took nothing short of magic and a very intense bath to even look remotely functional by the time they were able to even sit for breakfast.

Thankfully, the meal helped, and the head researcher was quick to give a report to the Princess. Insisting the two of them go to the chamber below the castle. Curious to know what they had managed to learn, they followed him. All the while, the head researcher went on and on about how ancient the site is, the cultural significance of it, as well as many other boring things both alicorns were a little too distracted to pay attention to.

“And here we are!” The head researcher explained, gesturing to the chamber. Cadance and Frosty only let him continue, trying their best not to blush as they saw the room where this all began. “Well, following the incident, we studied every inch of this chamber. Cross examined every sigil of all known and even lost languages, and we’ve finally cracked it!”

“By all means, please continue.” Cadance commented, not wanting to interrupt the researcher. “What have we learned?”

“This chamber predates even the first iterations of the Crystal Empire, a chamber of fertility ceremonies.” The head researcher explained. “You see, back in the ancient times, fertility was highly revered, and in such a harsh environment in the north, reproduction and foal birth was rare. So this chamber was designed and blessed by some enchantments to heighten the arousal and fertility of the mares and the virility of the stallions.”

“You don’t say.” Cadance replied, almost wide eyed as she was realizing what he was getting at. Nervously laughing, she couldn’t help but fidget a little. “And…how effective would this enchantment be?”

“Oh, by our estimations, not even magic, let alone modern medicine could prevent pregnancies in this chamber, or those affected.” The head researcher commented, looking more at the chamber than the royal alicorns. “Truely a miraculous site.”

“It really is.” Cadance replied, looking nervously at Frosty, who’s eyes were open wide in shock. Looking down at her body, she gently rubbed at her midsection, just above the womb. Using a little bit of magic, she could feel them, Frosty’s little swimmers, his hot and potent seed impregnating her eggs. There was no going back, she was now pregnant. Letting out a small sigh, she mumbled under her breath. “Well, shit…"
