Twilight sat at her desk, twirling a quill around in her magic. For the last could of days, she's been feeling agitated and bored. Unable to do any work or reading.
"Seriously, this is getting ridiculous!" She shouted, throwing a small book onto her bed. "Maybe a bit of light reading will help," she said with a shudder.
Naturally, for any normal pony, this book would be considered way too much for light reading, but for Twilight, this wasn't even close to heavy. She laid down on her bed and flicked her hair out of her face.
"I should really get that cut soon..." she mumbled, opening her book of Arcane Differentials to the first page and letting out a quiet hum.
The tried for an hour to read, but nothing was working. She switched books, twice, but still nothing.
Eventually, she decided that she needed someone with obviously a lot more experience in being bored than her, Princess Celestia.
Twilight leapt off her bed and walked over to the middle of the room. Her horn charged up with an ethereal purple glow and in a matter of seconds, she was hurtling away from her library and over to Canterlot.
She arrived with a crack and blinked the stars out of her eyes. "Where...?" She asked, before realization dawned. "The Princess's chambers!"
Her announcement was followed with the two doors opening; a loud creak signalling the sun princess's arrival.
Twilight sat in the middle of her room, in her rump, waiting. Celestia walked in with her serene smile and saw Twilight.
"T-Twilight... What are you doing here?" She asked, a nervous look making its way onto her features.
"I need some help!" Twilight shouted, forgetting who she was talking to. "Icantdoanythinfandi'mbored!" She threw out.
The door behind Celestia shut and she walked in further, "I'm sorry, can you repeat that slowly?"
"'m bored and I can't study..." Twilight admitted, embarrassment echoed onto her face. "I don't know why..."
"O...kay..." Celestia replied, taking a seat on her repaired bed. "Come sit with me and I'm sure we can find something for you to enjoy." Celestia patted the bed next to her and held a wing out to her student.
"Sure."
Twilight jumped up and laid down next to her teacher, nuzzling close to her warmth. "What did you have in mind?"
Celestia looked away, a slight blush visible, "Have you talked to Luna lately?"
It was Twilight's turn to blush and shuffled her ass which was still a bit sore. "Yes, a couple of nights ago, why?"
"Did she mention talking to me?"
"Only that you let her have the two nights off..."
"Two nights, I only said one..." Celestia mumbled, taking a mental note to punish Luna later. "Yes, I did." she said, louder. "Luna also brought up some good points regarding you..."
Twilight beamed, "Me? What did she say?"
"She...." Celestia stopped and a small grin worked its way onto her face. "Lulu loves you so much it hurt."
Twilight grinned, "Really!"
"You betcha!" Celestia nuzzled her student roughly, rubbing muzzles.
Twilight giggled and pushed Celestia away playfully, "Stop it!"
Celestia placed a hoof on Twilight's cheek and pulled her face closer, "Oh Twilight, I wanted to tell you..."
"Prince-"
Celestia cut her off, their lips touching. Sparks of electricity ran along their horns, intertwining at the tips. Twilight breathed deep and a flushed a bright red.
Twilight pushed her away more forcefully after realizing what was going on. "Celestia, what the Tartarus!"
"My student, rela-"
"Don't tell me to relax, you kissed me. You. Kissed. Me!" Twilight's eyes went wide as she imagined Luna striking her down with lightning as she ran through the streets.
Celestia chuckled and smiled at her frantic student. "Twilight, please!" she shouted, gripping her shoulders. "Listen to me!"
"She'll be so angry with me..." Twilight mumbled, going into some sort of haze.
A few seconds later and a flash of light made the two cover their eyes. "Twilight!" Luna shouted? Looking around and spotting her mare. "Twilight, I felt your magic, are you alright!"
Twilight jumped up, knocking Celestia's hooves away. "Oh Luna, this isn't what it looks like!" She made her way over with tears in her eyes, "I'm so sorry!"
"Pray tell, what are you sorry about?"
"I... Celestia kissed me... and I liked it..."
Luna's ears perked up and she gave a grin towards her sister, "I see..."
"Please don't be angry..." Twilight looked down, a tear falling to the floor.
Luna gazed down at Twilight with mirth and giggled, "It was about time you did something, sister."
Twilight frowned, "What?"
"Oh yes, I knew about Celestia's infatuation towards you." Luna thought for a second before smiling, "At least she finally worked up the courage, rather than clopping to a scry of you..."
"What's Luna talking about?" Twilight asked, turning to Celestia. "What do you mean scry?"
Celestia sighed and jumped off the bed, made her way over to Luna and placed a wing on her sisters back. "I love you, Twilight Sparkle."
"I-whu-what?!"
"Oh yes, very much so. Though, not as much as me yet." Luna added. "I expect she could, in time, match me." Luna smiled at Celestia, "I know I would like that..."
"Me too," Celestia said, nuzzling her sister.
As that went on, Twilight's mind had gone nuclear and had to be woken up by smelling salts.
"Huh..." she mumbled, jolting out of her daze. She looked over to Celestia and Luna standing here looking very worried. Twilight's face fell, "Oh, it wasn't a dream..."
"No, I do love you." Celestia held out a hoof and hesitantly, Twilight took it. She pulled her into her feet and kept her hold a little longer than usual.
"Princess... I..."
Celestia placed her hoof on Twilight's lips, "Don't worry, Luna still loves you and nothing will ever change that." Celestia pulled Luna forward, "We spoke the day before you two met last and came to an agreement."
"Twilight's eyebrows raised. "What agreement, to use me?"
"Good heavens no, of course not." Celestia looked shocked, "We would never do such a thing."
Twilight relaxed, "What then?"
"Well..." Celestia looked to Luna for guidance.
Luna nodded and smiled lovingly at Twilight, "We both love you, so I agreed that we could 'share' you for lack of a better term."
"Share me?!"
"Remember, my little sparkle, I still love you and I'm sure you do too." Luna cupped Twilight's cheek and she instinctively leaned into it. "There were times when ponies used to be in herds... Good times, alas, no more."
"I read about them..." Twilight said, brushing as she remembered the part about sex among herds.
"We remember when herds were the main family unit... We would like that with you."
"But you're... Sisters... You can't have sex."
Luna and Celestia glanced at each other and blushed. Twilight stood there slack-jawed. "Seriously!"
"Yes and it was so good," Celestia said, biting her lip. "You know, I could go for some more, Luna."
"Maybe in a bit, sis."
"But..."
"We are alicorns, we are all female... Excluding that one you killed, Luna." Celestia glared at her sister who shrank back. "No matter, we cannot mother foals anyway."
Twilight frowned and started to reassess the situation. "They love me... Both of them. They only want what's best for me and they are goddesses."
Twilight looked to Celestia and moved forward, she tilted her head and locked lips with Celestia, gently placing her hoof behind her head.
Celestia closed her eyes and leaned into the kiss, moaning ever so slightly. Their lips mashed together while Luna sat there watching, feeling pride for her mare and her sister.
The two came apart, a thin strand of saliva connecting them together. Twilight breathed in and smiled, "Yes..."
Celestia blinked and then grinned. The didn't respond and instead kissed Luna who squeaked and wrapped her legs around her sisters neck, melting into the kiss.
Twilight leaned in and pulled Luna away from Celestia and into her own legs. Their lips neared each other's and stopped to simply enjoy the moment.
Luna smiled and stroked Twilight's hair, "Why don't we move to the bed..."
Twilight hesitated, "I... Yeah, sure..." she looked over to Celestia who gave a loving smile.
"Don't worry..."
"I know," Twilight gave a quick smile back and followed Luna to Celestia's bed then jumped up.
"Why is it always my bed, when can it be yours?" Celestia huffed and laid down next to the others.
"We can go to mine if you'd like?" Luna tilted her head, "But you always say it's too cold. Though you always snuggle closer, so there's that..."
Celestia stuck her tongue out and placed a wing around Twilight, pulling her closer and into her chest.
Twilight inhaled Celestia's scent and nuzzled into her fur, "I missed this..."
"I know," Celestia whispered, "...my star"
Twilight gripped a little tighter and ran her back legs across Celestia's thighs. She let out a little gasp and nuzzled harder, "Are you wearing saffron dust?"
"No, my star, I am not," Celestia replied, grinning at Luna who's horn was alight with an aphrodisiac spell.
Luna's lips mashed against her sisters and the two of them fell into an embrace, with Twilight grinding in the middle.
Luna gasped and felt her own nether start to ignite. She saw Celestia's horn lit up with the same spell and narrowed her eyes. "It. Is. On," she whispered.
"Bring it, dear sister."
Luna's glow around her horn deepened its color until it was pure black. The intensity of magic around her horn made the light bend, causing it to look like a miniature black hole.
Celestia's horn glowed with the intensity of her sun with small bursts of magic acting as sun spots and throwing random mana off.
Twilight who was, obviously, oblivious to this, started to nibble and lick at Celestia's body, making the mare 'eep'.
The more magic that was poured into Luna's spell, the more horny Twilight became, until she ground her mare-hood against Celestia's leg.
Twilight moaned, "Oh yes, keep doing that Luna, more!"
Luna stared at Twilight in shock, "H-how..."
"I... Ah... Know your magic, ah, signatURE!" Twilight gripped Celestia's body as her clit ground against her knee, causing lightning to flow through her nerves.
Celestia grinned at Luna and quickly glanced at Twilight. Luna nodded and focused all of her magic at Twilight; Celestia did the same.
The result was instant and Twilight screamed out in pleasure as her fur stood on end and she came, twice. She fell back onto Luna who wrapped her legs around her sparkle, "Have fun?"
"Y-yes..." Twilight said breathlessly, "Round two?"
"Anything for you." Luna charged up her horn and a flash of light lit up Celestia's marehood. In it's place stood a replica of what Luna had the other night, but Celestia-sized.
Celestia grinned as Luna lowered her front and presented herself. "Please, master. Be gentle," she said, blowing a kiss and winking.
Twilight sat there in shock. "You have a... a..."
"Penis, dear," Celestia interjected. "Would you like one?" Celestia's horn lit up and Twilight's own nether started to form into a penis. Twilight sighed before grunting as she felt Luna wrap around her from the back and grip her newly formed body part.
"Bigger than mine..." Luna pouted as she ran a hoof along Twilight's dick, "Just."
"They are both amazing, I'm sure." Celestia smiled and looked at Twilight's penis with lust and hunger.
Twilight gulped and looked down. Purple with black splotches lined the shaft which ended in a pink flared head with white spots.
She looked back up with heavy breathing, "I have a penis..." she said, looking Celestia in the eyes.
Celestia chuckled, "I know, it's hard not to gobble it up." She then glanced to Luna, would you like to screw your marefriend?" Luna returned to her revealed position, "She's very eager to be filled..."
Luna nodded and grinned, "Please Twilight, I want to be your bitch!"
Twilight turned around and saw Luna's cunt staring her in the face. Immediately, her cock started to grow, making her coo and rise to her hooves.
"I feel... I want... I have..." Twilight tried to formulate the words, but they kept getting jumbled up inside her head. Only four words could be said without slipping up, "I love you Luna."
"Then rut me like you should!" Luna growled, "Make me scream." She used some magic and gripped Celestia's cock. "Can't leave my big sister blue-balled."
Celestia closed her eyes and sighed as the silky aura caressed and flowed its way across her dick, forcing her to lean back in fear of falling over. Her breathing deepened and she bit her lip to keep from moaning.
Twilight gripped Luna's rump and pulled herself up so that her cock was level with her mare's vagina and sighed. "This feels... right somehow."
"Strange, I was always the more dominant..." Luna shook her head, "Fuck me already!"
Twilight wasted no time and pushed the tip into Luna, making her shudder. "Ooh yes..." Luna moaned, wigging to boost the pleasure.
Twilight slapped Luna on the rump, "That's for the other night... My friends were curious as to why I was sitting on a doughnut..."
Luna grunted and growled, "Please, darling, fuck me or Celestia will!"
Twilight's ears perked up, "Celestia, fuck me as well!"
Celestia grinned, opened her eyes and shrugged before crawling over and lining up her penis with Twilight's anus. She rubbed it gently around the hole, making the mare coo.
"How do you like that?" Celestia asked, spanking Twilight. "You're just a bigger whore than Luna," she whispered into Twilight's ear.
"Right, that's it!" Luna used her magic to pick Twilight up, her legs flailing and forced her forwards until her penis was shoved inside Luna's warm, moist, inviting hole with an obscene squelch.
"Ooh," Twilight moaned, falling forwards onto Luna. She nuzzled Luna's cheek, her face red from embarrassment, "Why haven't I done this before..."
"Enough talk... I have waited a long time for you," Celestia said, moving behind Twilight and probing her cunt with her own tip, "Too long..."
Celestia took a deep breath and pushed forward, slowly inserting her dick into Twilight with a gasp. Twilight closes her eyes and shook against Luna, her legs griping tighter.
"Ah! Be gentle, I'm still quite tight..." Twilight asked, inhaling as Celestia entered her.
Celestia took heed and actually slowed down, giving Twilight time to get used to her size. She leaned down and kissed Twilight on the back of the head, breathing her scent in, "I'll go slow, for you."
Twilight looked back and smiled. "Thank you," her face grew red, "'tia."
Celestia kissed her on the nose and then moved past and kissed her sister, "Not getting bored are we?"
Luna rolled her eyes, "I could hold my erection all day if I wanted to... Plus, you could never bored me." she gave her sister a grin and swiveled her hips.
Twilight instinctively pulled her cock out and in, in turn making Celestia moan, "Twi, babe..." Celestia bottomed out with a sigh.
Twilight smiled and closed her eyes, enjoying the feeling of being sandwiched between two of the most powerful beings in the world, both of them essentially bowing to her in this instance.
She felt such a rush and forced her tongue into Luna's mouth, pushing her back onto the bed and fucking her.
Luna felt herself squeeze her lovers cock for all its worth, milking it for its precious seed. "Oh, Twi, HARDER!" She shouted, wrapping her legs tighter and helping her mare into a better position.
Celestia surprised by her ferocity quickly started and slammed her dick into Twilight's cunt.
Twilight used her magic to quicken Celestia up, "Fuck..." she muttered, "Oh fuck, oh fuck..."
She shuddered as her first orgasm raged through her body and fell onto Luna, a quivering mess.
Luna smiled and stroked her hair, "Hon, I know you're in bliss, but can you fuck me... now."
Twilight nodded and on shapely legs rose. She levitated her penis to Luna and quickly found her rhythm again.
Twilight bit the edge of Luna's ear gently, making Luna gasp and shut her eyes, cooing.
Celestia grinned and pounded Twilight harder, taking great pride in her ability to make her student let out grunts and lust filled moans. She bit her lip as she found herself close to blowing her load and slowed down to preserve the pleasure for everyone; she didn't want it to end too soon.
"Ah... AH," Twilight grunted, shaking from having herself filled to the brim with more-meat. "Oh, Celestiaf faster please!" She cried out, desperate for release.
Luna snorted, not to be outdone by her sister and slammed her muzzle into Twilight's, locking lips and ramming her tongue down her mare's throat. They wrestled tongues, but in the end, Luna's more experienced and stronger one won, holding the other down and exploring her mouth, then ultimately making its way down her moist hole.
Twilight gagged, at first, but then got used to Luna's wet appendage, enhances by a quick lengthening spell to be quite pleasurable and found herself moaning as it basically tongue fucked her esophagus.
Luna felt Twilight's walls clench and her grip around her dick strengthen. Twilight pulled on her coat and shook, releasing her mare-juices inside Luna and all over Celestia.
Luna retracted her tongue and brought her hoof down to her own, engorged, clit. She groaned with satisfaction as she rubbed it furiously, closing in to her own release.
Celestia was also close and quickened her pace so she would blow close to the same time as her sister. This was a special day and nothing say special more than, "Cumming inside a loved one at the same time as your sister."
Twilight laid there on top of Luna, simply taking her mentor's cock. She simply didn't have the energy to carry on and this way, she would get to enjoy herself either way.
A couple of seconds was all it took for the other princesses to cum together. Luna gasped and let out a lengthy moan, signalling she had her orgasm. As soon as Celestia heard, she grunted and then inserted herself fully, pumping her baby batter all over Twilight's sensitive and rippling walls.
Twilight gasped as she felt the boiling seed touch her flesh and clenched her eyes shut as she battled through the slight pain.
Celestia tumbled back onto the bed as she sighed happily as her penis shrunk back down to resemble a normal clitoris.
Luna gently licked Twilight's cheek, cleaning her, much the same way a mother would care for a foal, then said, "I'm glad you enjoyed this."
Twilight grunted and pushed herself up, "How could I not, I got to experience something that nopony ever has, even if it did sting..." she reached round and gently rubbed her sensitive slit.
Luna giggled, "I guess she should have told you... though you get used to it after a few hundred years."
"I guess you would..." Twilight said, snuggling down on the bed, her own penis sliding out of Luna with a wet 'pop'. She blushed at the thought of doing this for a long time to cum and smiled as Luna joined her next to Celestia.
Celestia turned and wrapped her wings over the two after using a cleaning spell. She kissed Twilight and Luna, "Goodnight you two. I love you."
