Twilight sighed and stretched her arms lazily as the hot rays of the rising sun met her through the window of her royal summer escape. She had a just finished a late and lazy breakfast in a bright and cosy room and was now ready to tackle her lazy holiday. Goodness, she loved having a chance to be lazy!

And she especially loved it here: At some point in time, Princess Celestia had renovated this old and sturdy lighthouse off the coast of Equestria. Time and the advent of the steam-engine had opened new trading routes and made this particular beacon obsolete. Therefore it was the perfect place for the sun princess to disappear to whenever she managed to find some free time in her usually tight schedule. Ever since the pier had been rotted away, the place was only reachable through teleportation, the small island was far enough off the coast to be extremely hard to reach and provided much privacy. It also helped that it had a wonderful beach and a big pantry.

Perfect for a short vacation far away from the tough world of politics and courtly responsibility.

And watching the sunset from atop the old tower was so romantic, Twilight could not be thankful enough that Celestia had taken her on this wonderful trip. It also amused her endlessly that the guiding beacon of hope, that was the sun princess, made her holiday home in a lighthouse.

As the young woman cleaned out the remains of their breakfast, she took in the cosy atmosphere and the simple beauty of the interior. It reminded her of good old Golden Oaks. Smiling softly, Twilight looked outside and a smirk appeared as she saw a very familiar divine princess making her way towards their favourite spot on the beach.

“Couldn’t wait for me to get some of her sun in…” Twilight said while shaking her head with a small grin. If there was one thing that topped seeing Celestia, then it had to be seeing Celestia in her bikini.

Eagerly, Twilight changed into her own bikini, a simple tube top with an almost embarrassingly conservative pair of bottoms. Never go bikini-shopping with Twilight Velvet. Finally, she packed a small bag of other beach items and followed her princess down the narrow path to the sandy shore.

What awaited her was both surprising and bemusing at the same time: Priness Celestia of Equestria, the lady of the sun, the ruler of a nation, the banisher of Discord, Sombra and Nightmare Moon and the 7 foot titanic leader that was adored by men and women alike… was happily sitting on the beach with a small shovel and a bucked and was about to build a sandcastle.

Twilight blinked a few times and decided to rub her eyes. But the picture did not change: Celestia was still wearing a white triangle bikini with her sun motive on the left top-triangle, a hip cloth and a baseball cap. She had her long, flowing hair in a gently waving ponytail and she was shovelling sand into a bucket.

“I didn’t know you brought THOSE kind of toys…” Twilight said bemused and laid down a towel close to the princess.

Celestia let out a soft giggle and grabbed behind her, producing a filled watering-can. “You can be so stuck-up.” She began to water the sand in the bucked and looked to Twilight. “I always build sandcastles when I’m on the beach. It’s so relaxing and calming.”

Twilight shook her head softly and sat down, her eyes on her happy princess. “It’s just one of those thing I didn’t expect to see in this life…”

“Neither did you expect to see me place a trail of kisses around your navel. Yet it happened yesterday night, correct?” Celestia answered with a smirk, earning a blush from the purple haired girl.

“Well, yes, but sandcastles?” Twilight said, shaking her head slowly “The pranks I understand… but this seems a bit out of character.”

“Actually, I got into it at the edge of the Renaissance. The advent of modern siege weapons made castles basically obsolete and the ones made of sand are so much cheaper. Let alone razing them… Four months of sieging and keeping morale up are poison for the soul.” Celestia said with a laugh and turned the bucket around on the ground. As she lifted it, a nice round bucket-shape of sand stood on the beach.

Twilight bit her lip. It was true: Celestia had seen the horrors of war over and over in her time. She had led Equestria against monsters both literal and metaphorical and ensured that there was peace in the present. Others would have turned into bitter, distant balls of rage. Her princess was happily shovelling sand with a song on her lips. Still, this demanded more teasing! “The classic paintings of you usually showed you towering over the known world with an air of wisdom and benevolence. They never showed you playing in the sand.”

“Oh, you have only seen the ones available to the public.” Celestia laughed merrily and began to dig out a moat for her new castle. “Maybe I’ll show you the more… risqué ones in my private collection. You’d be surprised how many artists tried their hand in erotica of me.”

“That sounds both intriguing and a bit creepy.”

“Oh, they meant no harm and I always found it flattering.” The sun princess giggled softly, now focusing more on her digging.

“Maybe another time.” Twilight yawned and turned to lie on her belly. “I didn’t catch much sleep last night due to somebody showing me a very romantic sunset and then taking full advantage of my amorous state. Then there was something with a trail of kisses around my navel… so I guess I’ll try to get some sleep now…”

“Of course, dear, I’ll quietly build up another kingdom here. Can’t wait to share that with you as well!”

Twilight nodded softly at the suggestion. She was glad Celestia was so happy and closed her eyes, so only the sound of the waves and the scratching of the princess’ shovel remained in her world.

As Twilight awoke, probably hours later, she noticed that something soft was covering her back. And something scratchy on her legs.

Lazily, she moved around and what seemed to be sand fell off her lower body. She grabbed up and discovered that it was the cloth, Celestia had been wearing that was on her back.

“You sleep like the dead my dear-heart.” The princess giggled from the side, sitting on a towel next to Twilight’s.

“Hm?” Twilight muttered sleepily.

“You have to watch out sleeping on the beach, dear. My sun won’t hurt me but sadly I can’t dim her for you. I covered you up before you got a sunburn.” Celestia explained further and extended a hand to run through Twilight’s hair.

“Oh… thank you…” the slowly awakening student answered and looked towards the mentioned celestial body. She had probably slept through half of the day.

“Don’t mention it, my love.” The solar princess answered softly. “I had my fun with it…”

Twilight snapped awake in an instant. “What did you do?”

The princess offered a conspiratory smirk. “Hmmm… should I tell you or should I let you stew? Decisions, decisions…”

“Celestia, I swear I’m not kissing you for the rest of our trip if you don’t tell me what you did in my sleep!” Twilight threatened grimly “Not another quesadilla incident!”

A small pout formed on the princess’ lips. “You will never forgive me the quesadillas, will you?”

“Oh, I forgave you the quesadillas. But I will never FORGET the quesadillas.” The smaller woman answered darkly “Pranks are one thing but the quesadilla was pure evil! Now tell me what you did!”

Celestia sighed and nodded. She reached under her towel and revealed a bunch of seemingly fresh polaroids. It always amused Twilight that Celestia kept to analogue pictures, even though she did own a cell.

Twilight grabbed the pictures and took a look.

The first showed her soundly asleep from above. But where her lower back ended and her butt began, Celestia had covered her in sand downwards. Her legs were entirely encrusted with it. Celestia had also drawn gentle scale patterns on the hull and it all ended in a big fin. Pretty incredible how thin the sand must have been and yet it covered her figure very tightly. Celestia had even put a small flipper just below her hips, making her look like a very sandy mermaid. She was resting her hand on both her hands and next to her face, the princess had drawn a fishing hook and written “Best Catch of the Century!” in the sand.

A soft smile invaded Twilight’s features as she looked at Celestia’s handywork. “I must have slept like a baby if you managed to pull that without me waking up.”

“You deserve some rest. It’s our holiday after all.” The sun princess added “So… what do you think of my sandcastle?”

Twilight blinked for a moment and then remembered what the two had been talking about before her nap. It didn’t take her long to find the rather elaborate piece of sandy architecture next to their spot.

The construction almost reached Celestia’s hip with its tallest tower. The base was a hexagon at its base with each corner featuring a round tower reaching into the sky. Celestia had added a broad moat, filled with water, a huge gate and banners made of handkerchiefs.

“I have to admit that is the first time I see an eight sided castle…” Twilight admitted bemused.

“Oh, it’s for all of us.” Celestia smirked. “One tower for every element, Luna and I get one and one is for Spike. I figured he could use some privacy.”

Twilight giggled softly. “It looks nice…”

“And now for the best part!” the sun princess smirked and got up.

“And what would that be?”

“I already took a picture, so I can remember it but the most fun part is…” Celestia slowly approached the castle with a broad grin “BECOMING CELESTI-ZILLA!”

And Twilight was in shock as the most regal being in existence began to swipe down the towers she had erected herself. The castle toppled slowly but certainly as the solar princess roared and finally flattened the main building by jumping onto it knees-first.

Celestia got up laughing merrily and her laughter intensified as she saw the look on Twilight’s face. “What? I have fought so many monsters in my time, it’s about time I become one, right?”

“Yes… but such a monster? This sandcastle was built by a poor and overworked princess who just wanted to relax and have some innocent fun. And you annihilated it without any mercy!” Twilight said in a mock-dramatic voice, earning a giggle from Celestia.

“What can I say? Muahahaha?” the sun princess answered with a grin and got up, wiping the remains of her victimized castle off her legs. “But seriously now: You need some protection! Lay down on your belly and take that top off…” a naughty smirk crossed Celestia’s face “Or the other way around… I’ll do your back.”

Twilight rolled her eyes while getting back onto her stomach. “I don’t do strip-tease for a castle-crasher.” She muttered and pulled the tube top over her head, her young and perky b-cups firmly planted on the towel.

Celestia meanwhile wiped the sand off her legs and approached Twilight slowly. “Oh, how virtuous…” She said with a grin and grabbed the sunscreen bottle.

Twilight relaxed and expected to feel Celestia’s strong, caring fingers on her back, but to her surprise, she felt two legs and knees next to her thighs and a soft, perky butt on her own, slightly flabbier one.

Celestia was doing the reverse cow-girl on her bum!

“Now… about that sunscreen!” the princess giggled and grabbed Twilight’s left ankle.

“I can reach my own legs!” Twilight objected.

“No, you can’t! Try it!”

“Not with you sitting on my ass!”

“Exactly!”

Twilight let out a groan and surrendered to Celestia’s hands. She knew that her princess was in full “free time mischief mode”. A state of mind that she usually entered when the realm was safe, no petitioners were banging on the door, all letters had been sent and every nook and cranny of the castle and the school for the gifted were clean and neat. It was usually best to just surrender to it and let her have her fun. Usually the end result would be fun for everyone involved. Even if the path could be frustrating.

Celestia put a few cold drops of the squishy sun screen on the calf in her hand and began to gently distribute it on the leg. Her fingers were incredibly soft yet strong and powerful and Twilight did her best to swallow a slight moan as her leg was kneaded and caressed. Celestia was endlessly gentle and patient, gently stroking from her Achilles tendon down to her knee, stroking around her patella and back up again towards the ankle. Slowly she returned down again, this time further, tickling over the outside of Twilight’s thigh. Feeling that Twilight was reaching the brink of her flexibility, Celestia let go off the leg and grabbed the other ankle, pulling it up as well.

“You have really nice legs, you know… a fish-tail would ruin so much…” Celestia noted absentminded as she gently rubbed over Twilight’s calf. A mischievous thought jumped her head and the princess moved over finger over the sole of Twilight’s foot, earning a loud yelp and a lot of wiggling from the smaller woman.

“Don’t do that!” Twilight yelled from below.

“Fine, fine…” Celestia sighed and continued to cover the leg with sun screen. Again, Twilight strained herself to not admit how much she enjoyed the strong, flexible hands kneading and caressing her. The princess knew how to push buttons that Twilight never knew she had!

Finally, the leg was let go and with a quick movement, Celestia turned around, now looking down at Twilight’s back while still half-sitting, half-hovering over her butt.

She heard how Celestia squeezed another load of sunscreen out of the tube and expected two warm, slippery hand to dance over her back. She was severely mistaken. Instead two massive, firm and fleshy mounds rubbed over back, hot as the sun and slippery like sin.

Twilight sucked in air as she felt two slightly harder nubs on the mounds leave hot trails on her back and her arms flexed in surprise. “She is rubbing her breasts over my back! She is soaking me in sunscreen with her breast!” her mind screamed. Twilight gritted her teeth, the closeness and pure eroticism of feeling Celestia’s soft chest sent fire through her whole body. It was a miracle how well Celestia’s curves had survived the hardships of time. Even after thousands of years, they were magnificent. Sure, Twilight considered herself a demisexual and breasts didn’t do much for her, but this pair went beyond such barriers. Even straight girls would motorboat those!

A soft moan escaped her and she surrendered completely, lying on her belly as her back was being covered in more ways than one.

Finally, Celestia stopped her treatment and just rested on top her lover.

Again, this pushed a button deep down in Twilight’s psyche. Maybe it was due to Celestia’s sheer size or maybe it was a bit of a submissive streak of her, but she loved feeling Celestia on top of her. The weight, the warmth and the sheer safety. It was as if nothing in the world could reach and hurt her. And Celestia knew exactly how much pressure to put on her to make it work.

Suddenly she felt two hard, hot teeth close around the rim of her earlobe and bite down softly. She sighed, her head turning without resistance as Celestia pulled and nibbled gently.

“Stay on your belly….” The princess muttered into Twilight’s ear “It’s unprotected…”

Twilight didn’t resist or complain. Celestia had set up the rules and she would follow them because it led to more of this.

The princess sat up and slid back, off Twilight’s butt and just behind it. “Oh, look at you! You haven’t been in the water all day…” One of her hands went down and toughed Twilight’s slightly damp slit.

“It’s just sweat, I swear!” Twilight interrupted quickly. Getting bothered over being a mattress and some nibbling! That was just humiliating.

“Sweat doesn’t have your scent of delight…” Celestia giggled. And pushed.

Twilight gasped as two firm fingers pressed her bikini into her budding flower. The rough texture of the inlay rubbed over her sensitive spot. Fire spread through her loins, hotter than the sun on her back could ever be. Celestia knew exactly how to push her most sensitive buttons.

“Almost enough for another moat…” Celestia giggled, her eyes growing a bit wider as Twilight groaned under her sensuous attacks. But she knew that Twilight needed more and she knew how to give it.

The princess carefully began casting spells, first levitating a good amount of sand into the air. She put some distance between the sand and twilight and called upon a bit of the sun’s fire. After a few magical adjustments to the form and a quick dousing of the cold from between the stars, the princess levitated a very hard, very smooth and perfectly shaped object into her had.

“Twilight! I made another sandcastle!” Celestia giggled as she pressed the object against Twilight’s moist entrance.

“WAH! Where did you get that from?!” Twilight screamed in panic. She turned her head and looked at the object Celestia held up for her. It had a dark, grainy look, but it was clearly smooth and had a matte sheen to it. “You made a dildo out of glass?” she asked incredulously.

“Oh, love, I am older than plastic and rubber! I can make a dildo out of anything!” Celestia laughed merrily. “And don’t worry, its hygienic. My heat disinfects all!”

“I’m not worried about tha-AAAAA!” Twilight gasped as Celestia penetrated her flower with the slightly warm object. It was smooth, hard, and so delightfully fitting. It stretched the young woman just enough to give her this wonderfully feeling of fullness. Celestia quickly found and rhythm and enjoyed the cacophony of gasps and groans she would earn from her beloved. Her other hand slowly reached down her own body, tracing over her muscled belly down to her own, moistening bottoms. But no, she would wait. Twilight’s gratitude would be sweeter than anything she could do to herself. Instead she began rubbing and squeezing Twilight’s firm buttocks. The student gasped at the feeling of a soft hand pushing under her bikini, greedily squishing and groping her supple flesh. Her toes curled at the feeling of Celestia’s fingernails digging into her skin.

“Celestia! Not so… I’m-AH!” Twilight gasped as her princess picked up the pace, now ramming the glass shaft faster and faster into her twitching folds. Twilight felt the fire of her loins intensifying, her moans now echoing over the beach.

Suddenly Celestia felt Twilight’s folds clench down on the dildo and Twilight let out a loud “OHHH!”. The princes twisted and pushed forcing Twilight to ride out her climax as hard and long as possible until the pupil’s folds relaxed. Twilight let out a gasp as the burning fire of orgasm slowly burned out and only a soft heat remained. She felt Celestia pull her new toy from her quivering folds and heard her stand up. A numbness began spreading through her legs. God, this was a good one. The girl looked to the side and saw Celestia sitting down next to her all while licking the dildo as if it was a Popsicle.

“We have those in the freezer…” Twilight wheezed, slowly getting breaths again.

“Not nearly as good as self-made ones, my dear.” The princess teased. “Now turn around… we have to do your front now.”
