Celestia sat in the tastefully decorated office twiddling the tips of her hooves as she waited for the doctor to return. She may have looked calm and composed, but in her chest she was a ball of nerves and tension.

For months she had been stressing and obsessing about this day.

The day she visited the fertility clinic.

Being a good ruler and helping her subjects was all she had wanted since first being crowned. Being the only ruler for over a thousand years meant she didn't have time to think about being a mother, but now Luna was back, and now that Twilight had become a princess, she started to think about it more and more. She wasn't alone as a ruler anymore, meaning Equestria wouldn't fall apart if she wasn't on the throne.

The thought of having a child of her very own both excited and scared her, but before that, she had to find out if she could have a foal.

The door to the office opened as a mare in a white doctors coat entered.

"Good afternoon, your majesty," the brown unicorn mare greeted as she came in, holding a manila folder with her magic.

"Hello, doctor. Have my test results come back yet?" She asked, feeling the butterflies swarm in her stomach.

The doctor opened the folder and quickly breezed through the papers.

"Yes they have, but I'm afraid you won't like what it says."

Celestia felt her heart drop into her lap.

"Oh, my. Can I not have a foal?"

The doctor gave her a sympathetic look.

"Well, according to the tests, you hit menopause some centuries ago."

Celestia lowered her head and sighed. Inside she knew before coming in that she wasn't going to get good news. Being thousands of years old meant that she was well past the age of conception.

"I'm so sorry, highness, but there are other ways. Using a donor egg for artificial insemination, a surrogate mother."

Celestia stood from her seat.

"Thank you so much, doctor. But this has helped me come to a descision."

~Three months later~

The orange light of sunrise shined in through the large window as Celestia quietly moved about the large bedchamber as not to wake the sleeping colt on her princess sized bed.

She smiled warmly at the grey colt as he snoozed with the cutest look on his face.

She had adopted Drizzle Drop after learning that she couldn't have a foal of her own, and she had never been happier. She and the little colt had bonded almost instantly, he didn't even hesitate to call her mommy.

Celestia had taken on lighter duties so she could spend time bonding with her little Drizzle. Luna, who had told her older sister that she had her full support, said she had no problem taking on some of Celestia's duties for her while she and Drizzle bonded.

But today was to be a sad and proud day for Celestia and her new son.

Today was his first day of school.

She moved to where the little colt slept peacefully, leaning over and giving him a kiss on his forehead.

"Drizzle, sweetie, it's time to wake up," she cooed.

Drizzle stirred and stretched before looking up at his mommy with a sleepy smile.

"Mommy, are the cookies ready yet?" He asked, still somewhat in a dream.

Celestia giggled at her adorable colt's question.

"No, sweetie, it's time to get ready for school."

"Mmmmm, ok, mommy," he sighed before drifting back to sleep.

Celestia smiled and rolled her eyes. She used her magic to pick up the little grey colt and laid him on her back. She moved into the bathroom and wet a rag with warm water. Drizzle slowly woke up as she used the washcloth to wipe his face and clean the sleep from his eyes.

"Are you excited for your first day of school?" She asked the waking foal.

"Sorta. What do ponies do at school, mommy?"

Celestia picked up his little blue toothbrush and applied a dab of paste before holding the end to his lips. Drizzle opened his mouth, and Celestia began brushing his teeth.

"Oh, all sorts of things. You'll learn things like math and spelling, and you'll get to meet and play with other fillies and colts."

Celestia raised a glass of water to Drizzle's mouth so he could rinse. He swished the water in his mouth before spitting it back into the glass.

"Will you be with me at school mommy?" He asked as Celestia lifted him off her back and set him down on his hooves.

Celestia felt her heart flutter. She wished she could be with him.

"I'm sorry, sweetie, but school is only for little ponies," she explained as she picked up a comb and started brushing Drizzle's messy black mane.

"Mmmmmm," he pouted, sticking out his lower lip.

"Now, now, my little Drizzle. I'm sure you wouldn't want your mommy there embarrassing you."

"You wouldn't embarrass me. My mommy is the coolest mommy in all of Equestria!" He proclaimed with his chest out proudly.

Celestia felt her heart beat quicken. She couldn't have been happier to have such a sweet and sensitive little colt as her son. She had known and helped many mothers in her life. But she never knew a mothers joy and pride until Drizzle came along.

Celestia swiftly wrapped her hooves around Drizzle and nuzzled his head, messing up all the brushing she had done. He was so soft and warm, and his sweet little colt smell made her giddy and filled with peace every time.

"Mommy, can we play before I go to school?"

Celestia's eyes shot open at her son's question. She bit her lip while looking at the clock above the mirror.

"I-I'm sorry, sweetie, but we don't have time."

Celestia held her breath. Since bringing Drizzle home she hadn't said no to him once. She hated denying him. She wanted nothing more than to flop onto her back open her legs and- no! There wasn't time. If he was going to throw a fit, then he was going to have to throw a fit.

"Oh, ok mommy," he replied, sounding somewhat disappointed.

Celestia ran a hoof over his soft mane.

"We'll play once you get home from school, I promise."

Drizzle smiled up at his mommy. Celestia felt silly for thinking that her sweet little colt would throw a tantrum. He was such a good boy.

"Private Strong Hoof," she called to the earth pony guard posted outside her bedchamber door.

"Yes, your majesty?" The guard asked, opening the door slightly.

"Bring the chariot around, we shall be departing soon."

Strong Hoof nodded once before galloping off to retrieve the royal chariot.

……………….

The chariot came to a slow stop in front of Canterlot pre-school. Celestia set Drizzle's saddle bag on his back, feeling her motherly instincts well up in her chest.
She knew it was silly, but she couldn't help but worry about her precious little baby. What if he got home sick? What if he got bullied by the others?

Her train of thought was interrupted when she felt Drizzle's little hoof touch her own.

"It'll be ok, mommy. I'll see you after school."

It was all she could do to not burst into tears then and there.

She hugged him, and him her, Celestia giving him a big kiss on the head.

"Thats right, sweetie. Now you listen to your teacher, and pay attention, and I'll see you this afternoon."

Drizzle hoped down from the chariot.

"Bye, bye, mommy. I love you."

"Bye, bye, sweet heart. I love you too."

She watched with tears in her eyes as he galloped off, finding a group of little ponies. All of them ran off and started playing together.

"Your majesty, shall we get going? I have orders to have you back at the castle as soon as possible."

Celestia wiped a tear from her cheek.

"Yes, private, let us away," she said with some difficulty.

Private Strong Hoof took off on the road back to the castle. He had been a personal guard for the princess for almost a year, and he couldn't help but sympathize with her. She reminded him of his mom. The day he told her he was joining the royal guard she cried for an hour. At his graduation he almost needed an umbrella to shield himself from the waterfall of happy tears.

"Dont worry, majesty. He's a smart kid, he'll be ok."

Celestia smiled while taking a deep breath through her nose, feeling calmer from the act.

"Thank you, private," she said simply.

………..

Celestia yawned as she walked down the large hallway. The meeting she just came from was the first she had attended in three months, and it was just as long and boring as she remembered.

A mirror mounted on the wall caught her attention. She had noticed it for some weeks now, but seeing herself in the mirror really showed it. Her rump was…..bigger, her hips more wide, and she had noticed her teats had grown in size as well. Where they were once only cones under little pink nipples, now they were closer to the udders of a cow, her nipples a little longer.

She liked the new changes to her body, it made her feel more feminine. She contributed her bodily changes to an excess of estrogen in her system. Being a mother made her more beautiful, she reasoned.

She struck a pose, sticking out her rump and puckering her lips, giggling to herself as she did so.

"Uhh, sorry to disturb you, your majesty."

Celestia jumped, quickly followed by straightening her appearance. She turned around to see private Strong Hoof standing behind her, a confused look on the young stallion's muzzle.

"Oh, uh, private. What is it?" She asked, hoping the private didn't see too much.

"It's almost noon, majesty. Shall I get the chariot to pick up prince Drizzle?"

Celestia had been so distracted by her own rump (not the first time that happened) that she hadn't even noticed the time, but she felt greatly elated that it was time to pick her little Drizzly up.

"Yes, yes, absolutely!" She cheered to her young guard.

"Right away, princess."

………………………………..

Celestia sat nervously in the golden chariot as she waited for the bell to ring. She realized as she waited that this was the longest she had been parted from her baby since she brought him home.

"What if he doesn't remember me? What if he eloped with some filly while at school? Oh sweet stars! What if he joined a roving gang of pegasie and went off to rob a bank?!"

She noticed that she had started biting the tip of her hoof when she snapped out of her motherly freak out.

An abrupt ringing sound broke the silence, telling her that school had concluded. She watched patiently for a glint of Drizzle as little fillies and colts swarmed out of the school.

Out of the mob came a grey colt carrying a blue saddlebag. The happy little colt hoped into the chariot and was immediately swept up in a warm hug from his mommy.

"Mommy, school is so much fun!" He muffled from within his mothers bosom.

"It was? You weren't lonely? The other ponies didn't bully you? You didn't even miss your poor moth-"

"Mommy!"

Celestia was again snapped out of her mania.

"Oh, sorry, sweetie. How was it?"

Drizzle flashed his mother a big grin while wagging his tail back and forth.

"It was really cool! I played hide and seek, we ate peanut butter and jelly sandwiches, and I made you a painting."

Drizzle dipped into his saddle bag and pulled out a crudely painted picture of Celestia on a grassy field with a big splotchy sun behind her. Her mane and tail were a mish mash of every color mixed together, obviously an attempt to copy her rainbow etherealness.

She loved it.

She clutched the painting to her chest and cuddled it like it was a stuffed rabbit, making an elated squee as she did so.

"Oh, my sweet little baby. I love it! We'll have to hang it in the royal gallery!"

Her eyes shifted from the painting to the little foal looking up at her with those adorable baby blue eyes of his, and suddenly she couldn't contain herself any longer. Using her magic, she picked Drizzle up and planted a big sloppy kiss right square on his forehead.

Drizzle didn't complain, but private Strong Hoof took notice and started pulling the chariot back to the castle to save the poor kid the humiliation of being seen smothered with kisses by his mom.

Celestia finally broke her kiss with a loud pop, setting her son down next to her. Celestia was positively beaming with motherly pride. Here she was stressing and obsessing about the most ridicules scenarios, and he was just fine. He wasn't afraid of school, he was excited.

Drizzle was more than just a child for her to care for. For centuries Celestia had to be brave and courageous for the sake of her subjects, but she was filled with anxiety and fears, and without Luna she had to face it all on her own.

But Drizzle……….he gave her courage.

She may have been the princess of the sun, but he was her sun.

"Mommy, we're gonna play when we get home, right?"

Celestia smiled down at Drizzle, his eyes filled with excitement and hope.

"Of course, baby."

Her response was calm and soothing, but in her head she was hoping up and down like a filly on hearths warming eve.

……………….

Private Strong Hoof went to park the chariot while Celestia and drizzle entered the palace.

Celestia carried herself with her signature royal demeanor as she watched Drizzle hop and gallop through the entry hall, eager to start their long awaited play time.

"Your majesty, your presence is requested in the meeting hall."

Celestia's stomach dropped to the floor. She glared with venom at the guard who took her out of her elation.

"Who?" She snarled.

"Uh, it's Filthy Rich. He says he needs to discus next months trade arrangement," the guard replied, shaking in his golden boots.

Celestia growled, her mane taking on a flaming demeanor.

"Mommy, is everything ok?"

Her son's sweet little voice broke her from the growing rage.

"Yes, sweetie. Mommy just has some work to finish up and then we can play."

Private Strong Hoof entered the hall then, scanning the room and assessing that the mood was sour.

"Private, please take prince Drizzle to our bed chamber and wait for me to return," she commanded, to which the private saluted and escorted the young prince down the hall.

Celestia bit her inner cheek as she stormed to the meeting room.

She was going to give Filthy a piece of her mind.

…………………..

Fifteen minutes later saw the princess of the sun in no better mood than she had when she entered the meeting room.

"The nerve! The nerve of that greedy, bit pinching cur! To demand that I allow a ten percent interest increase on trade goods!"

She vented her anger to a room filled with her royal advisors. The assembled group of ponies exchanged nervous glances as the princess fumed figuratively and physically a little, a fine steam rising from her royal head.

"I-is there anything we can do for you, highness?" One pony asked nervously.

Celestia turned and looked on at her advisors.

"I am going……to go play……with my son! I had better not be disturbed……"

Nopony objected as the princess left the room, maintaining her royal saunter as she left.

………………….

Private Strong Hoof sat with the young prince as the two played with building blocks. Together they had constructed an almost exact replica of Canterlot castle, with the addition of a big tower in the middle with lots of cannons.

Cannons are cool.

Being the go-to play mate had been the young guards un official second job since the prince came to the castle. He didn't really have much experience with little kids, but prince Drizzle wasn't loud or crazy like other little ponies, he was really laid back and sweet, and Strong Hoof started to see him as like a little brother.

"Strong Poof, why is mommy taking so long?" The young prince asked.

Strong Hoof wasn't crazy about his nick name. He got it one day when Drizzle planted a whoopee cushion under Celestia's chair. It was meant to play a prank on his mother, but Celestia saw how tired the private looked from playing with Drizzle and told him to sit and rest.

Hence, Strong Poof was born.

"Well, your mommy is a very important pony. She works hard to make sure that everypony is happy."

"Ohhhhh. Is mommy like a boss?" The little colt asked with a cute tilt of his head.

Strong hoof ruffled the little scamps mane with a hoof.

"Yes, champ. Like a boss."

The two continued to stack blocks on top of each other.

A moment later, the door opened and Celestia walked in with a smile that said she was trying to hide her irritation. Drizzle sprang up and started bouncing in place.

"Mommy, mommy, mommy!" He cheered, running up to his alicorn mother where he was picked up with her magic and held in a snuggle against her face.

"Majesty, is everything alright?"

Celestia lowered Drizzle and gave the private a reassuring smile.

"Yes, private, everything is fine now."

Strong hoof admired the princess for more than just being his ruler. Growing up with a single mother, he saw how hard it must have been for the princess, and being so important meant she had to juggle motherhood and princessness together.

"Thank you for watching Drizzle, you can take off for the evening."

Strong hoof smiled before going to attention and saluting the princess.

"I'll see you tomorrow, majesty."

"Bye, bye, Strong Poof, 'tee, hee'."

The private left the royal bed chamber, Celestia locking the door behind him.

She turned now to the little colt who had been patiently waiting for his mother.

"Is there a little colt in here who wants to play?" She asked with a sultry voice.

"I do, mommy, I do."

Celestia giggled before removing her crown, neckless and slippers. She then laid down on her side and opened her back legs, exposing her plump teats.

"Now come here, little boy," she cooed, beaconing him to her with a hoof.

Drizzle's face lit up bright as a star. He bounded to where Celestia lay, but stopped just shy of her.

"Mommy, aren't you gonna bring it out?"

Celestia realized that she had forgotten about 'that'.

"Oh, silly me. Of course, my dear."

Her horn lit up, and an aura of golden magic enveloped the place between her legs. In an instant, a large pair of white, veiney balls came into existence, followed by a long grey and white splotchy horse cock. It laid flat to her underside almost up to her chest, the thick length of it pulsing with her rapid heartbeat.

The large organ made a wet sound as it was released from its restraint and plopped to the floor.

Celestia intended to keep her "princesshood" a secret from her adopted son.

Until that one time.

It happened one night when the two were in the royal baths. She couldn't help it, seeing her little Drizzle playing and splashing with his little toy boats made her feel so relaxed and comfortable that she didn't even notice that she lost control of her concealment spell, her fat cock splashing loudly as it hit the water.

It was the most awkward and embarrassing thing ever to explain to her son what the large length of meat between her legs was.

She explained that since mommy was an alicorn, she had both boy and girl parts.

Fortunately, Drizzle was a very smart and understanding boy. She just didn't expect that he would want to "explore" his mother's naughty bits.

Of course Celestia was going to tell him no, but she thought about it. Drizzle had never known his birth mother, so he never got to experience close bonding with a mare to develop skinship.

So………….she did it.

And never regretted it.

"Wow, mommy, it looks even bigger today than it did yesterday."

"That's because mommy has been waiting all day for our playtime," she replied, using her tail to lightly brush his face.

Drizzle reached out to touch his mother's throbbing penis, but was stopped when she lightly slapped his hoof.

"Ah-ah, what are the rules, mister?"

Drizzle groaned.

"Words used during playtime are only to be used during playtime."

"And?"

"Places touched during playtime are only to be touched during playtime."

"One more for the win."

"What happens during playtime doesn't leave playtime."

Celestia smiled and gave the eager foal a single nod.

Without hesitation, Drizzle jumped on his mother's fifteen inch long dick and clamped his mouth on the head. Celestia winced at the long awaited oral contact form her colts sweet little mouth.

"S-slow down, sweetie. Mommy's eager to play too, but if you start so suddenly she'll-NNNNNNNGH!"

Celestia tensed up as she felt herself blow a big load inside Drizzle's tiny mouth.

Drizzle's eyes shot open when the first load of his mother's come hit the back of his throat. He gulped as fast as he could, but her thick seed flooded his throat and oozed out from around his soft lips.

Celestia put a hoof on the back of his head to hold him in place while he drank and gulped her batter as best he could. She bit her lip, feeling her balls tighten and flex as they finished emptying themselves into the colt's mouth.

Drizzle kept his lips sealed around his mother's cock to suck out the leftover jizz still inside her urethra, lapping at the flaring head still in his maw.

Celestia released her grip from the back of his head and let her still stiff cock flop out of his mouth.

"Whoa, mommy! That was a lot. You're still hard too!"

Celestia sighed, trying to regain her composure after coming so hard.

"That's because mommy loves you so much," she whispered, using a hoof to wipe a glob of sploog from his cheek.

Drizzle smiled and swooned against Celestia's long penis, moving his head down until his face was nuzzled between her orange sized balls.

"'Tee hee', You're such a mama's boy, Drizzle. Sometimes I think you love my balls more than my breasts."

Instead of a reply, she felt Drizzle's mouth start suckling on her left testy like he was breast feeding. He used a hoof to massage her other testicle, gently kneading the tender white flesh.

Celestia watched with growing hunger at Drizzle's little rump as he stuck it up and waggled it back and forth. She licked her lips as she imagined how good it was going to feel sliding herself into that tight little tail hole.

She levitated a pillow over and rested her head on it, reveling in the amazing feeling of a little colt's mouth sucking her balls. Drizzle was perfect for this kind of "play". being so young, he had no hesitation in exploring things that felt good. He loved cock, and even better, he loved his mommy's cock.

Drizzle alternated his sucking between hard and soft, switching it up with long, broad licks up her sack, savoring the taste of his alicorn mother's ball sweat.
Venturing lower, he found his mother's slit. He had never played there, and the idea sorta made him curious. He swiped his tongue up the pink slit, tasting Celestia's musky juices.

Without warning, an aura of magic enveloped him and lifted the young colt from his mother's nethers.

"Ah, mommy……?"

"Drizzle, sweetie. Fun is fun, but I'm sorry, mommy can't let you play there."

Drizzle liked that place, but if mommy said no, then there was a good reason.

"Ok, mommy," he agreed, somewhat disappointed.

"Besides, mommy is still hard, and I can't wait to feel myself inside you," she purred through half lidded eyes. Drizzle smiled sheepishly, wiggling his butt while he hung in the air.

Celestia turned and set Drizzle down on his belly with his rump hanging off the edge of the bed facing her. He threw his tail up and back, exposing his little pink tail hole. His own cock was small, even for his age, only three or four inches long, but it was the cutest little thing Celestia had ever seen.

Many nights she would simply hold it in her mouth, rubbing her tongue along the sides and then coiling her tongue around it while Drizzle sucked his hoof and drifted off to sleep, all while Celesia hummed a lullaby to him.

He wasn't old enough to ejaculate, but sometimes he would reward her with a dab of his sweet pre. It was so thin and clear, but to her it was better than Pinkie Pie's most famous punch.

But it wasn't his little colt hood that had Celestia slack jawed and drooling with a goofy smile on her face this afternoon. His puckered pink button was completely exposed between his tight little ass cheeks.

It looked so sweet and juicy, like a pink cherry between two scoops of ice cream!

Celestia sat on her plump rump and leaned in, smelling deep the scent of his ass, which was sweet and pungent.

"Mommyyyyyyyyyy! You know it embarrasses me when you smell my bum……"

"Ohhhh-but mommy can't help it! Mommy's little baby has such a cute little boy pussy…"

Drizzle felt his cheeks get hot, and he averted his eyes to the bed under him. He liked it when mommy used bad words during play time, but it still made him feel funny in his tummy and between his legs, and feeling her hot breath on his puckered tail hole made it worse.

Celestia's tongue fell from her open mouth, the tip slowly drawing closer and closer to his opening.

Drizzle made the cutest squeak of surprise when he felt mommy's tongue touch his butt hole. It wriggled and snaked around the tight ring, coating it in her warm saliva. Celestia's brain was quickly turning to pink jelly as the sweet and heady taste of her sons ass hole coated every taste bud on her tongue, she took broad licks up his hole, up his crack and stopped just shy of the small of his back before moving back gown and starting her worship all over again.

Drizzle's eyes crossed, and he gripped the silk sheets with his little hooves as tightly as he could, the sensation of mommy's tongue on his butt making him feel funny and good at the same time.

Celestia put the tip of her tongue right on his button and gently pushed it in, only getting a quarter of an inch inside the warm hole.

"NGH! M-mommy, my…my…..colt..pussy…feels good!"

Drizzle's moans and hearing him call his butt a "pussy" wrung out in Celestia's head like a beautiful song. She felt her huge cock twitch hard, telling her she needed to rut him NOW.

She pulled her oral muscle from his rectum, a strand of saliva connecting her tongue to his ass. She puckered, and gave the twitching hole a kiss before rising to her hooves.

"U-use your hooves to……s-spread yourself open, sweetie," she whispered between excited huffs of breath.

Drizzle slowly reached back, using his hooves to pull open his cheeks to further expose his mommy's target.

The act wasn't necessary, but Celestia loved the sight of her precious little boy spreading himself and offering up his rump to her like a mare.

"N-now, what are you going to say if mommy starts hurting you?"

"I-I say stop," Drizzle replied with his cheeks all ablaze.

"Thats right. But mommy hasn't hurt you yet. Your colt pussy has adjusted well to mommy's princesshood."

She licked her lips, placing her fore hooves on the edge of the bed to mount him. Using her magic, placed her cock between his cheeks, sandwiching it between his soft little cheeks. Her enormous cock dwarfed his rump, and Celestia loved the feeling of being between such soft, warm buns.

Her dick moved down until it touched his golden gate. With a grunt from both mother and child, his ass parted, welcoming the first few centimeters of Celestia's cock.

Drizzle let out a sweet little girl moan as he felt his mothers impressive girth fill his empty ass, touching his walls and coating her cock with his inner moisture.
Celestia felt her back legs tremble and weaken, the sensations in her penis filling her with tingly pin pricks of rapture. Her son's ass was so heavenly, it was all she could do to not slam herself down to the medial ring and impale the little colt on her length.

"So tight! He's hugging it! My son is hugging my cock with his aaaaas~!" She moaned internally as she sank deeper and deeper into his moist hole.

Drizzle continued to moan and squeak, feeling himself flex and relax around the hard penis in his tail hole. At first this kind of play made his bottom feel funny and uncomfortable, but seeing how much mommy liked his butt made him happy, and soon the uncomfortable feeling made him feel funny in a really good way.

Celestia took her hooves off the bed and placed them on his soft cheeks, her hooves almost covering his little cheeks completely.

Even though his asshole was so accommodating to Celestia's big dick, she could only get half of it in before his rectum got to tight to go further. But it was plenty for her.

She stayed still, trembling as she felt his rectum pulse around her. She massaged his blank flanks as she let him adjust to her girth.

"I-it's ok, mommy. I'm ok, and I-I know it feels good, so go ahead and start moving."

Celestia could tell what Drizzle was trying to say. He couldn't wait for her to start thrusting inside his ass. She knew how much he enjoyed this. The feeling of having a big cock deep inside his boy cunt, hollowing him out until she couldn't hold her boiling lust in any longer and painted his rectum with her hot come.

"Alright then, sweetie. Here comes mommy!"

With that she pulled her long cock almost all the way out of his ass, holding it just at the opening before pushing back in, making a wet sloshing sound as she entered him again.

Celestia felt her balls stir and shift from the stimulation in her cock. Her piss hole flared open when she bottomed out again, swiftly pulling out and pushing back inside.

Drizzle brought a hoof to his mouth and started sucking on the tip like a baby. He could feel his mother's hard cock push up against his tummy, filling his belly with a warm sensation.

Celestia bit her lower lip as she picked up her pace, moving faster in and out of Drizzle's loosening ass. Unable to stay still any more, Drizzle let his other hoof move down his body till he touched his own penis. He didn't know exactly what to do, but he started rubbing it gently with the tip of his hoof.

Mommy's grip on his flanks got tighter, her rhythm getting faster as the growing pressure in her balls drove her closer to cream pie her son's ass.

She fell forward, her hot and heavy breath tickling Drizzle's mane as she dripped sweat on him from above.

"Oh my sweet little prince, your mommy feels sooooo good in your rump," she whispered into his ear. Drizzle was beyond words. The burning friction in his ass had turned him into a hot and bothered little colt who was eager to feel his mothers cum ozz into his colt pussy.

Suddenly, out of the blue, Drizzle's body was stricken stiff as a rock. His anus twitched and clamped hard on the cock inside him, halting Celestia's thrusts. His mouth opened wide, and he threw his head back as far as he could, giving Celestia a great view of his face just as his baby blue eyes rolled back into his head.

He released a girlish squeal, the sound of which caused a devilish smile to crest her lips. Her heart fluttered, she didn't expect that today she would watch her baby have his first orgasm, nor did she expect to be the one to drive him to it.

It was beautiful to watch. His sweaty little face contorting with pure bliss and ecstasy.

He couldn't breath. All that he could do was release little breaths mixed with squeaks of desperation. Celestia closed her eyes and gave him a sweet peck in his forehead, the act seeming to bring him down a bit as his eyes returned and he fell forward on the soft bed.

"Shhhhhhhhhhhhh~" she cooed to him, nuzzling her cheek on the top of his head.

It worked in soothing him, as he was out from a mix of ecstasy and fatigue.

But Celestia wasn't done yet.

Using her magic, she picked up the light foal and moved away from the bed, her dick still inside his still twitching ass pussy. She closed her eyes as she continued to move the unconscious colt up and down on her iron hard dick.

She didn't take long to ejaculate. She closed her eyes and grit her teeth as her first burst of cum exploded inside Drizzle's tight little ass.

"GHAAAAAAAAAAA!" She groaned as the floodgates opened and she let go with a stream of jizz deep inside her son's asshole. Her back legs buckled, and she fell to her rump, continuing to erupt her thick seed. Come started to shoot out from around Drizzle's O-ring as her orgasm started to die down.

She set Drizzle down, rump up, slowly withdrawing from him.

Her head popped out of now gaping hole, her splooge oozing out and dripping down his thighs. Celestia took a moment to catch her breath, stroking Drizzle's head while she gently sang him a song.

Slowly the spent colt returned from the other side, slumping to his belly as he swooned into his mother's hoof.

"Mmmmmm. Mommy, that was a lot of fun."

Celestia giggled.

"Mommy had fun too. Are you alright, baby?"

Drizzle reached between his legs and gently touched his distended asshole. The little ring closed beautifully, releasing a little dab of cum.

"Mmhmm. I'm ok, but what was that that happened to me, mommy?"

"Well, sweetie, that is what's called an orgasm."

Drizzle rolled onto his back and looked up at Celestia with a quizzical expression.

"Like what happens when you kiss mommy's penis, or what happens when we play, sweetie."

Drizzle's eyes grew wide, and he grinned like he had reached a great revaluation.

"Does that mean that I've grown up, mommy?!"

Celestia smiled warmly down at her little scamp before bending down and blowing a raspberry on his soft little belly, to Drizzle's laughing joy.

"Maybe just a little," she teased.

"M-mommy? I need to go potty."

Celestia nodded, picking him up and carrying him to the bathroom. She set him on the toilet so he could take came of his business. She gathered a wad of baby wipes and used some to clean her face of sweat and her cock of it's left over come. She waited for Drizzle to finish before she picked him up and cleaned him from head to hoof of his own sweat, cleaning every speck of her semen from his body.

After they were both clean, Drizzle went back into the bedroom and moved toward his building blocks to play, but Celestia stopped him.

"Drizzllllle. It's time to eat, mister. We need to get you to bed, you have school tomorrow, remember?"

Drizzle looked up at her with a pouty face.

"But mommyyyyyyyyyy!"

Celestia only gave him a stern glare.

"Butts are for play time, young colt. I did ask Miss. Soufflé to make your favorite dish, buuuuut….."

Drizzle's mouth opened wide, visibly watering.

"You mean……roasted carrots with holidays sauce?"

Celestia touched a hoof to the tip of her nose.

Mother and son both walked down the halls to the royal dining room, Drizzle smiling widely and humming happily as he walked next to his mommy.

The two enjoyed a nice meal together, Celestia taking a piece of carrot and dipping it in sauce before popping it into Drizzle's open mouth.

Celestia had just lowered the sun, but Drizzle was already so tired that he was falling asleep. She carried him on her back and laid him in bed, covering him with a blanket.

"Good night, my little prince," she whispered to him as he sucked his hoof peacefully.

Celestia then found his painting and left the room to hang it in the royal art gallery as promised.

She perused the paintings on the walls for one that she could take down. She found a spot that belonged to an expressionist painting by an artist named Visage. She found the painting much like she found the stallion himself, which was dull and tasteless. Drizzle's painting was a much better fit for the spot.

"Tia, what in mother's name are you doing up at this hour?"

The beautiful voice caused Celestia to look to her left with a big smile.

"Lulu!" She exclaimed to her beloved little sister.

The two got close and rubbed their horns together, the act of which caused little sparks of magic that conveyed feelings of love and affection for each other. The two had done this since the time they were little fillies.

"Drizzle fell asleep, thank goodness. So I came to hang this painting he made for me," Celestia explained, holding a hoof up to the painting like it was a rare treasure.

Luna shot Celestia a hurt look.

"And what ever did you do with the painting I made for you when we were fillies?"

Celestia deadpanned a glare at her sister, pointing with a hoof down the hall. At the end of the hall was mounted a painting of two little ponies, one white with a pink mane and tail and the other blue with a blue mane and tail. Between the two was a large pink heart, which looked like it was done using the artists hoof.

The painting was mounted in a gold frame that was accentuated with rubies, sapphires, and white jade, two display lights shining on it from two angles.

"Oh," Luna replied, her cheeks blushing as she flashed a smile.

"Honestly, Luna. I'm offended that you would think that I wouldn't keep something you gave me."

Luna used a hoof to rub the back of head head.

"Apologies, sister. I was foolish."

Celestia nuzzled Luna's head. How could she stay mad at her sister?

"How is your boy? Today was his first day of school, was it not?"

"Indeed, and he accomplished it with the glory and stride one would expect from a prince of Equestria," Celestia commented as she looked fondly upon his art work.

"He sounds like a joy, and we could not be happier for you, sister. Perhaps one day I shall have one of his like."

Celestia felt a cold sensation in the pit of her stomach. She had yet to inform Luna of there inability to bear young. Luna had assumed that her decision to adopt was her first and only option.

"Luna……how would you like to have a sleep over with Drizzle?"

Luna's face turned bright red, her eyes shot open.
