"Pardon me, Highness?"

Celestia tilted her head to the side, glancing slightly back at private Strong Hoof, who was using his hoof to scratch the back of his head.

"Yes, private? Is something the matter?"

Strong Hoof briefly contemplated how to address his ruler, but couldn't quite come up with anything. Like usual, he and the princess were waiting outside of the young prince's grade school for classes to dismiss. The difference this time was that the princess had absolutely insisted on waiting among the throng of other parents for her son.

"It isn't that anything is wrong….just that, well," the young stallion hesitated as if there was something he didn't want to say out loud.

"With respect, majesty. You sort of…stand out."

Celestia's eyes widened. She looked around, noticing that not only was she noticeably taler than everypony else around her, but that the other parents were all staring at her. She suddenly felt embarrassed, and worried that she might get mobbed by the them at any second.

Fortunately, the school bell rang at that moment, followed by a herd of little fillies and colts exiting out the front of the school. Celestia's eyes immediately zeroed in on the black mane of her precious little boy. Her golden clad hoof flew up into the air, waving to her little one with great fervor.

"DRIZZLE! DRIZZLE BABY, OVER HERE!" She shouted to the foal, who was within talking distance.

Strong Hoof sighed, fighting back the urge to face hoof. Drizzle's face lit up as he dashed and leapt into his mother's hooves. She squeezed him tightly, nuzzling his mane and taking in the sweet scent of the little colt. The collected parents seemed to be touched at the heart warming sight of a mother and son.

Celestia swiftly spirited her son to the carriage, and before long they were on their way back to the castle. Drizzle seemed to be very excited about something, which was evident by his big smile and antsy movements as he sat next to her. Celestia was about to ask him what he was so happy about, but decided against it, thinking that he would tell her when he was ready.

Celestia relieved her Private, knowing that it was his mother's birthday.

Drizzle seemed to skip along down the halls as he and Celestia made their way to the royal bed chamber. Celestia had to bite her lip as she watched Drizzle's tight little bubble butt bounce around as he happily trotted along. Celestia had seen, explored, and had her princess cock deep inside that juicy little crack, but she couldn't help feeling excited every time she looked at it.

At that moment, she wanted nothing more than to bend her head over slightly and push her tongue inside his tight, pink hole. As soon as they were in Celestia's room, the princess closed and locked the door as Drizzle turned on his hoof and beamed a smile to his mother.

"My goodness, sweetie. What has you so excited?" She asked, tilting her head slightly.

Drizzle stuck his face into his saddle bag and pulled out a sheet of paper. Celestia took the sheet with her magic and brought it closer to inspect it. It was a test, and it had a big red '100' at the top of it with the equine letters spelling out 'great job!'.

Celestia felt her heart glow like her own sun.

"I did it, mommy! I did it!"

Celestia felt her pride swell like a balloon in her chest. Everything turned into a blur as the alicorn wrapped her colt up in a big hug that threatened to force the air out of his little lungs.

"Oh, Drizzle! Mommy is soooo proud of you! Your lessons with Twilight must have paid off."

No real surprise to Celestia. If there was anypony in Equestria that would guarantee that Drizzle would pass it was Twilight.

She set her now slightly dizzy son down and beamed smiles down at him.

"You were right, mommy. Aunty Twilight is amazing."

"Now now, sweetie. Twilight may have helped you, but it was you who worked hard and earned your passing grade. You should be very proud of yourself."

Her son sat up straight, puffing out his chess with pride. Celestia couldn't help but giggle at how adorable he was. Suddenly, though, she felt something tingle between her hind legs. Celestia wasn't un-accustom to interesting sensations from her nether reagin, but this time it wasn't coming from her long dong. This time she was feeling a burning, nagging from her mare parts.

Celestia gulped hard.

She slinked backwards onto her large bed and sprawled out on her back with her legs open.

"Drizzle sweetie," she called sweetly to the little colt who was still busy with his poses.

The young prince looked over at his mother laid out on the large bed, her mommy parts wet and pink. Drizzle was suddenly a foal caught in the headlights as he gazed with a slightly opened mouth at the opening that was beckoning to him.

"Mommy's going to give you a really nice reward now, sweetie. Now come her and have a taste while it's still hot."

An aw struck colt approached the edge of the bed and climbed up, coming face to face with his mother's swollen pussy lips. The pungent smell seemed to waft exclusively into Drizzle's nasal passages, coating his brain in a warm, pink fuzz.

"No need to be shy, baby. Mommy wants you to give her a kiss right here," she whispered, pointing to her monist opening.

Drizzle opened his mouth and let his tongue fall out. Celestia bit her lip as she watched his mouth inch closer to her already sensitive pussy.

All of a sudden, it was like Celestia was hit with ten thousand volts. Drizzle's little, pink tongue sloppily worked its way within her depths. His big eyes altered between looking up at his mother and back to her plump mound. Celestia openly vocalized her enjoyment, while her mare parts coated his cheeks in her sticky, clear juices.

Drizzle had only done this with his mother once so far, so he wasn't too sure what to do.

As if sensing her baby's uncertainty, Celestia used a hoof to tilt his head up so that he was looking at her.

"That's good, sweetie, but why don't you try sucking like how mommy does to you," she cooed to the eager little pony.

Drizzle nodded, looking down at Celestia's pussy. He opened his mouth and tried his best to suck his mother's pussy into his mouth. Using all his ability, he sucked as hard as he could. Celestia instantly felt herself loosing her composure as her little boy gave her an amazing pussy blow job. His little mouth made adorable little wet sucking sounds as he closed his eyes, using his mouth to slurp and blow his alicorn mother's marehood.

Celestia felt her eyes roll into the back of her head as her back leg twitched spastically. Drizzle had only given her cunnilingus once so far, but if this was any indication of his future talents then Celestia was sure he was going to make three other princesses very happy.

His slick little tongue suddenly found Celestia's pearl as it emerged, and instantly sent the ivory mare over the edge and spiraling into orgasm.

Her orgasm was mostly silent from Celestia bitting her lip. Her hooves held Drizzle's head between her legs as she washed his mouth out with her clear, hot liquid. The surprised colt's eyes shot open as his mouth was filled to bursting. On instinct, he started gulping. The load of liquid orgasm wasn't nearly as thick as the cum mommy had fed him in the past, so Drizzle was able to gulp it down with little effort.

Celestia rode her orgasm for another minute before her body went limp, leaving her panting and smiling. The sun princess loved a good female orgasm once in a while. It was refreshing and reminded her of the days when she was an adorable little filly touching herself for the first time in a flowery field in the Everfree forest.

Drizzle raised his head like he was coming up from holding his breath under water. His lips and cheeks were wet and glossy with his mother's love.

Celestia smiled at her baby, gently touching his cheek with her hoof.

"That was very good, sweetie," she praised, drawing a shy blush on his face.

"Drizzle baby, as a reward for your good grade, mommy is going to let you do whatever you want today."

Drizzle suddenly hd a look on his face as if asking "whatever I want?", to which Celesia nodded once with a smile that betrayed the royal princess.

"So, baby, what would you like to do first?"

Drizzle was a buzz with ideas of all the things he would like to do with his mommy. He hesitantly opened his mouth to speak.

"I-I really want to…to kiss you mommy."

The princess' heart almost stopped right then and there. There was no doubt that Drizzle was going to grow up to be a real princess slayer. Most stallions wouldn't hesitate to jump into sex, or anal, or a blow job. But Drizzle wasn't just thinking about his own enjoyment, he wanted to seduce his mother as well.
Not that he needed to, Celestia was so hot and wet that she feared she would cum from the next touch.

With a seductive giggle, her horn lit up, and she levitated the colt to within kissing distance of her muzzle. Drizzle was suddenly struck by an invisible wave of her pheromones, causing his head to swim and his heart to beat faster.

Kissing was nothing new to them, but something about this seemed completely different. Both of their berths were thick and heavy, and their eyes were locked onto the others.

They closed their eyes and came together. Celestia let Drizzle take the lead, using his small lips to open hers as his tongue passed the opening and entered her muzzle. Instantly her mouth was filled with the sweet taste of his saliva. His small organ swirled around her larger one, the small colt moaned and sighed into her, while Celestia did her best to stifle herself from moaning wildly.

Her hooves glided down his sides o his little blank flanks, where she massaged them in little circles. Their kiss got more heated as it continued till it was a mashing of lips and tongues.

Finally Drizzle parted from his mother's hungry mouth, panting heavily, his mouth glistening with his and Celestia's saliva.

Celestia smiled with a sultry glint in her eyes.

"I want to…to kiss your…"

"Kiss my what, sweetie?"

Drizzle looked down as if he was ashamed.

"Your butt…mommy."

Celestia blushed. She had been a bit conscientious about her ample rear. More so since it seemed to have grown bigger lately, but if Drizzle wanted it, it was his.

She set him down on the edge as she got up and turned around, laying down so that he had access to her big, round flanks. Drizzle gazed upon the royal plot like a filly at a big chocolate cake. He placed his comparatively small hooves to the mounds of white meat, marveling as they sank in to the warm mounds.

Celestia sighed gently from her son's touch, gently moving her rump as he massaged her butt.

"Please don't stare at mommy's plot so much, honey. Mommy's embarrassed about how big it is," she cooed in an adorable tone.

"I don't think it's too big, mommy. I think it's really pretty."

The sun princess felt herself blush. Drizzle used his hooves to open her ample cheeks, exposing her taint and anus.

Celestia gasped from the feeling of Drizzle's moist tongue touching her asshole, feeling unbelievably glad hat she had cleaned herself extra down there. His small organ circled around her winking ass, caressing every wrinkle. Celestia giggled to herself, clenching her cheeks around Drizzle's soft cheeks, nearly smothering the foal.

Drizzle wasn't slow down though. He kept licking and wriggling his tongue against her resisting sphincter.

"Come on, baby, you can do it. Get right inside mommy's asshole!" She pleaded internally. She really wanted Drizzle to put his tongue inside her ass, but she also got an amazing feeling of depravity in watching him work so hard for something he wanted.

His saliva coated her anus, making entry a little easier. With some pushing and prodding, his little organ finally broke through her resistance and slipped inside of her. The alicorn princess threw her head back with a mouth wide open in a small, silent orgasm. Her rectal walls clenched tightly to the unknown intruder, but Drizzle's tongue just kept sliding inside.

Once he was in as far as his little tongue would go he started swirling his tongue around, tasting the inside of his mother's rectum.

"Mmmmmmm! That's so good, sweetie!" Celestia moaned, biting her lip.

Drizzle moved his hooves around in circles on Celestia's big rump. The soft, plush fur was smooth as silk, and cheeks were getting warmer as he rubbed. Her ample rump wasn't the only thing getting warm. Her pussy was so wet now that Celestia was sure that she was making a wet spot on the bed.

"D-Drizzle, baby, mommy can't wait anymore," she stated in a pleading tone.

The little prince pulled his organ from his mother and sat back, his face red and him out of breath. Celestia transitioned to her back, opening her legs and revealing her soaking wet princess pussy. In his sitting position, Celestia could see his little pink cock standing up against his body. She licked her lips as she eyed he misty little morsel, remembering how yummy it felt inside her.

"Come on in, Drizzle. My door is always open."

Drizzle hesitantly moved atop his mommy till the tip of his cock touched her moist opening. He could feel his mother's enormous cock under him, though he couldn't see it because of her concealing spell. His warm little body wasn't even long enough to cover her whole shaft, but Celestia loved how he felt on top of it.

Drizzle shifted and wiggled as he tried to find his mark. He thrusted up, but his cock only slid along her pussy, stimulating her exposed clit and causing the sun princess to shudder. His next attempted thrust went down and touched her asshole. This caused Celestia to throw her head back in another mini orgasm.

Fun was fun, but if Celestia didn't get her son's little cock in her pussy now she was going to lose her mind.

With her magic, she angled his shaft at her opening, and with her hind legs she wrapped around him, pulling him in and causing a wet smack to sound out from the place they were now connected.

Celestia's heart raced as she felt something warm and thick spurting inside her vagina. Her tongue lolled out, and her head filled with bliss as the feeling of Drizzle coming inside her replaced everything else. The little colt clung to her tightly, his hips twitching with every burst of seed.

His little moans and squeaks were so cute that Celestia could feel her pussy oozing with even more arousal just from listening to them. She took a deep breath, stroking her son's mane to comfort him. Drizzle recovered quickly, looking up at his mother with a quizzical expression.

"You can do whatever you like, sweetie. Mommy is rewarding you, remember?"

Drizzle's face lit up with excitement. Her held on tighter to his mother's middle, slowly moving his still hard penis around inside her. Celestia bit her lip from the incestuous pleasure. Drizzle's cock wasn't fully 'developed' yet, but the tip touched her sweet spot ever so slightly, and it was pushing her to yet another climax.

His mother's soft breasts were pressing against his chest, and he could feel that her nipples were hard. They jiggled and shifted under him as he humped faster. He wanted to hear mommy moan, to make her feel as good with his penis as mommy made him feel with hers. He focused his movements, trying hard to match his breathing with his thrusts.

Celestia quickly began to notice that his pounding of her sopping cunt was getting better, harder and even more amazing. His hips bumped against her, making a low thumping sound as they met.

"D-does it feel good, m-mommy!?" Drizzle asked, sounding needy.

Broken from her pleasure induced daze, Celestia looked with lust crazed eyes at the little pony between her legs.

"It feels amazing, sweetie! Fuck me! Don't stop until I cum all over you!"

With his mother's insistence, Drizzle closed his eyes tight and began thrusting with all his might. His pink penis burned inside Celestia's pussy as she squelched and spurted his juices more and more. The sun princess tilted her head back, her mouth falling open and her tongue lolling out.

In the most un-princess like way, she moaned long and loud, to the joy of her son.

His little cock felt like it was going to explode, his mother's pussy felt more amazing than the first time time he had sex with her. She was moaning wildly as he pounded as hard as he could.

Celestia could see a white light in the distance, and she galloped as hard as she could to reach it.

"M-mommy! I'm comming!"

Drizzle threw his head up as he slammed himself inside her and blew his load. Celestia touched the light in her eyes and came with a wave of cum all over, showering Drizzle's body in her pleasure.

Drizzle could feel her pussy sucking him in, holding his colt hood in place as his cock leaked his fluids and cried in his little voice. As if her pussy wasn't holding him hard enough, she wrapped her hind legs around his hips to hold him in tight while she lost her mind to orgasmic bliss.

The spent colt collapsed atop his mother, nuzzling into her soft, white coat. Celestia held her baby as she panted, her face wet with sweat. She stroked his mane, giving him a moment to recover before she moved on to their next round.

Fifteen minutes later and Drizzle was sitting on the edge of the bad, his mother sitting on the floor before him with his cock inside her mouth. To Celestia, his little colt hood was the sweetest treat since she ate a slice of that cake the Pinkie Pie and the other bakers brought to the bake off. It was warm at the tip, and the shaft was smooth and tender in her gently sucking mouth.

"I-it tingles, mommy. I just squirted," he whimpered with hint of pleasure and pain in his voice.

Celestia's almond shaped eyes looked up at him with glazed over lust as she slurped up his short length till her moist lips popped off the tip. Her magic replaced her mouth as she giggled seductively.

"You made mommy feel good with your mouth, I'm just returning the favor, sweetie."

With her golden aura of magic she was able to fondle his little balls as she lapped at his head like it was a lolly pop.

"You know, sweetie, mommy really loves your cum, so don't hesitate to give her a nice big mouthful."

With that she engulfed his colt hood, coating it in her hot drool as she slurped like a slut. She couldn't tear her eyes away from the sweet sight of his cute little face in ecstasy. His little moans got louder and shriller as she amped up her sucking. It wouldn't be long now till he popped for her.

Drizzle started thrusting his hips up into her mouth as he huffed harder and faster. Celestia let his have his way, but she needed to assert a little control. With her magic she made a long, thin rod and started prodding it against his asshole. Drizzle hesitated as he felt the foreign object slide up inside of him. He cried out in ecstasy as the rod slid deeper into his rectum till it touched against his prostate.

"M-Mommy!" He cried out, clenching his ass tight.

Celestia wrapped her tongue around his cock while squeezing his balls. His little scrotum clenched as he moaned and came three hard spurts into the back of his mother's throat.

Celestia held back the urge to cough from the spurts that hit her throat. She kept her lips sealed around the base to keep any of his semen from escaping. After Drizzle stopped trembling, she started pulling her mouth off of him, popping her lips off of the tip. Celestia held his warm cum on her tongue as she noticed Drizzle looking at her with a weary expression.

With a sly grin, she swooped up and sealed her lips to his, using her tongue to push his own cum into his mouth.

Drizzle tried to pull back a bit, but Celestia had him in her clutches. Soon their tongues were swirling together as they exchanged cum and saliva. Once Celestia was sure that all the cum was inside his mouth, she pulled back.

"Swollow it," she commanded sweetly.

Drizzle hesitated slightly before tilting his head back and letting the thick seed to slide down his throat.

Celestia giggled like a filly.

"Well then, baby. What would you like to do next?"

Celestia laid facing the head of the large bed, her big ass pointed toward the little colt who was gazing with amazement upon her ample rear. Drizzle's request was that he get to try anal sex with her this time.

Celestia wiggled her rump at her son, which swayed from side to side. She then started bouncing her meat buns up and down like a professional stripper. Her cheeks clapped as they bounced them, all while Drizzle watched with eyes so large they nearly popped out of his head.

Setting her big ass down once again, she used her magic to pull her cheeks open, exposing her winking, pink anus. Drizzle's colthood was hard and ready, but there was one little problem.

Drizzle mounted his mother's ample rump, his fore hooves resting on the small of her back. He pushed his hips forward, but found that the tip of his dick only made contact with air. With a determined face, he kept pushing and prodding, but he couldn't find anything.

"What's the matter, sweetie? I thought you wanted to have butt sex with mommy."

Drizzle kept struggling, but to no avail. His frustration and failed efforts were making him sniff and feel like crying. Celestia's motherly instincts kicked in once she heard him sniffle.

"Oh baby, what's wrong?" She asked with worry.

"I-I can't reach it…m-mommy."

Celestia realized it then. Drizzle's dick was so short and her ass was so plump it was impossible for him to get to her asshole. The princess knitted her brow in disappointment that she wasn't going to feel her baby's cum pouring inside her ass, but she wasn't going to let him go wanting.

"There there, my baby. Mommy might know something that's almost the same."

Just when he was about to ask after what she meant, when suddenly she clenched her cheeks, encasing his dick in a thick cocoon of hot ass meat.

"M-mommy, that feels good!"

Celestia giggled to herself, enjoying the feeling of holding her son's little tool in her butt.

"Really? I'm so glad to hear that. Once you're ready, you can start moving, sweetie."

Drizzle swallowed as he pulled his hips back, feeling the pull of Celestia's cheeks on his shaft. He sighed gently from the new stimulation, while Celestia inhaled sharply from the sensation of his cock rubbing against her plush coat.

Once he was almost free, he pushed himself balls deep into her deep crack. The deep part of her crack was hotter than the earth's core, and Drizzle had to concentrate so that he didn't cum too soon.

"Don't keep mommy waiting, Drizzle. Pound mommy's rump like a drum," she cooed to the cheek fucking colt mounted behind her.

Not wanting to disappoint his mother, Drizzle stared moving faster, matching his thrusts with his breathing. His pelvis gently collided his her butt, but even the gentle slapping caused waves of ripples to spread over her snow white mounds. Celestia was beginning to sweat, making her rump slick for Drizzle's thrusting.
Her rump jostled, and she was loving the subtle yet firm pounding that Drizzle was giving her.

"How are you liking it so far, honey?" She asked cooly, knowing that he was loosing his mind.

"Your butt is so soft and squishy, mommy. I-I love it soooo much!"

"Tee hee, then don't hold back, sweetie. Mommy's rump is aching for some harder pounding."

Drizzle's little hooves gripped hard to her cheeks as he started bumping against her with all his little might. Sweat dripped from his forehead, adding to the beads already covering her plump orbs. Her inner cheeks held tight to his cock, nearly sucking him in as he used her ass to beat his burning meat. Drizzle's little balls collided with Celestia's gushing pussy, which soaked them with every collision.

"Fuck, honey! Mommy's so wet!"

Drizzle only heard a slur of muted words as his body thrust with full force into her cushiony backside. Celestia wrapped her etherial tail around his chest and started forcefully pulling in rhythm with his movements. Their movements were wet and sloppy, and the sound of a little colt panting and slamming his cock between her rump was a sweet and sick sensation that delighted the princess greatly.

"Mommy, I'm gonna cum!" Drizzle cried out desperately.

"Do it, sweetie! Give me a big fat cream pie right between my cheeks!"

He pushed in as far as her squishy cheeks would allow and blew his load. Celestia felt the hot spurts of cream fill her buns and ooze out the top, pushing her over the edge. Her pussy squirted so much it was like she was peeing, and her cock squirted a fat load of princess cum all over the bed.

Drizzle moaned like a filly, which only aided Celestia in her own climax.

Drizzle's orgasm lasted another ten-seconds before he collapsed onto his mother's back. Celestia shivered with post orgasm and soon realized that her baby had collapsed onto her back. She smiled, wrapping her big wings around him like a blanket. Them and the bad were both a mess, but she decided that a little nap was fine for now.

It'll all come out in the wash anyway.

It was around nine at night when Celestia decided to leave a sleeping Drizzle in the freshly cleaned bed and take a stroll through the halls. She was just admiring a new crystal chandelier when a glimpse of midnight blue drew her attention.

"Ah, sister, what brings you out at this time? Shouldn't you be keeping your foal warm whilst he slumbers?" Luna asked after she and Celestia affectionately rubbed horns.

"I needed to stretch my legs," she explained. "And this isn't the olden days, Luna. We aren't living in the forest where we needed to huddle together for warmth."

Luna chuckled.

"Times sure have changed. Though I do sometimes miss the feeling of closeness we used to share."

Celestia smiled, but soon felt a twinge of sorrow at the fond memory.

"Yes…back when it was the three of us."

Luna suddenly looked like she had said something she shouldn't have.

"Apologies, sister. I did not mean to bring up painful-"

"No, Lulu, it's alright. I'm glad to have these memories of her, even if they do sometimes hurt."

"Indeed," Luna added.

The two sisters nuzzled each other briefly before pulling away and smiling at one another.

"I'm glad that I ran into you, Lulu. There's something of importance that I wanted to speak with you about."

Luna's brow knitted in quandary.

"Of course. Whatever could it be, sister?"

Celestia dawned a devilish smirk that sent chills up her little sister's spine.

"I want to start planning…Drizzle's coronation."

Luna's cock sprang to life and started throbbing like a heart. She felt her mouth water as she displayed her own smirk.

"Oh yes, indeed. That is something worth…discussing."

Author's Note

Drizzle's ass is in for a wooooooorld of pounding.
