Celestia can't get Twilight off her mind and she's worried it's starting to become rather unhealthy. The answer might be found at the bottom of a bottle or end of a quill or between the unicorn's loins. No matter where it is found, Celestia is pretty sure she already knows the answer.

Trigger Warnings:Sex

What? Oh, fine. Don't be adventurous.

Hornjob, light hoofing, futa, oral, and masturbation. Happy now weirdos?

The Quill is Mightier than the Dildo

Celestia had dreamt of this for a long time. Just her and Twilight, alone in a darkened room behind locked doors, cuddled close together on a soft, warm bed.

Twilight was nervous at first, of course, but she was inexperienced, if she was experienced at all. Celestia was slow and gentle, easing her young, vibrant student into it. It didn’t take long for Twilight’s nervous whimpers to turn to moans as Celestia allowed her talented tongue to go to work on Twilight’s horn while a hoof gave her the pleasure she needed below.

It had been too long since Celestia had done this. She had forgotten the thrill she always got when she took the lifeblood of another magic user into her mouth. A unicorn’s horn was, by nature, blunted and due to its extreme sensitivity, only crazy ponies even tried to sharpen it to a point, so there was no danger to her. But being a goddess with centuries upon centuries of life and strength under her, she could very well snap it off with her teeth.

She didn’t do that, obviously. That would be cruel, and she could never be cruel to her sweet Twilight. She was almost ashamed, doing this now, claiming her student’s innocence.

Almost.

Twilight’s horn was warm against her tongue as she coiled the oral muscle around the magical organ. The grooves made her imagine what it would be like to feel it inside a different orifice and that thought brought a moan from Celestia’s throat.

Just inches below her lips, she could hear Twilight’s breath coming in increasingly shallow gasps as the unicorn rapidly approached her bursting point. Celestia couldn’t help but grin as the horn in her mouth grew hotter and Twilight began bucking her hips against the alicorn’s hoof.

With a cry, Twilight suddenly filled her mentor’s mouth with warm magical fluid while simultaneously soaking her hoof and the sheets beneath her with her juices. Celestia pulled her lips off of Twilight’s horn, her mouth still full of the unicorn’s ejaculated magic. She swirled it around like she was tasting a fine wine. It tasted of grapes. Or was that raspberries? Mulberries perhaps? Maybe it was

The sharp cracking of her quill breaking jarred Celestia from her musings. She looked down with annoyance at the large splotch of black ink soaking the parchment. For a moment she considered using a bit of magic to remove the ink and preserve what she had written, but only for a moment.

She tossed the broken quill in the nearby trash bin and rolled up the scroll before tossing it in the fire that blazed in the fireplace. It was pointless. She always got caught up in the details. The details were always the most important. They made it seem more real.

But it wasn’t real. Twilight Sparkle was asleep in her room near the castle library, Spike either curled up in his basket or beside her, and Celestia was here, alone in her bedroom, trying to vent her frustrations with ink and quill.

It was unfair. She practically raised Twilight herself, treating her like the daughter she never had. And she loved it. Reading to Twilight, sharing meals with her, teaching her, tucking her into bed at night, it stirred a warm feeling in her breast that had not been there in centuries.

And then Twilight blossomed from a cute little filly eager to learn into a ravishing mare with a near unquenchable thirst for knowledge. And suddenly, Twilight didn’t need her anymore. Twilight could read any book she wanted, even teaching herself a translation spell so she wouldn’t have to ask for help from somepony that read a language she did not. Twilight, a lonely filly looking for companionship, was now a mare with her own little baby dragon to look after. Gone were the days when she would snuggle up against Celestia in the alicorn’s bed, snoozing in the comforting warmth of her wings. Gone were days when Twilight would simply follow Celestia around from sunup to sunset, pestering her with the cutest questions. Now, she saw her only at lessons, which were increasingly infrequent, as Twilight was just teaching herself now.

It was almost as though Twilight was avoiding her….

With a snort, Celestia shook her head.

While she didn’t necessarily want her little filly back, she still wanted her Twilight. She wanted Twilight to be hers and hers alone. She had used the word ‘ravishing’ or ‘desirable’ or even ‘delicious’ when thinking about Twilight, and especially whenever she tried writing. It wasn’t a maternal instinct anymore, if it ever was.

Celestia sighed as she drew another quill from the jar on her desk and pulled a fresh sheet of parchment from a stack. It was very unbecoming of her, having thoughts like this about Twilight. This little obsession of hers was merely a phase. Yes, just a phase.

So four years is a phase now? said a very obnoxious voice in her head.

Yes, she replied, dabbing the quill in the inkwell.

You’re talking to yourself again.

Shut up.

Celestia pressed the ink-laden quill to the parchment and began writing again. This time she would do something better. Something more productive…

“Ah!”

Celestia heard Twilight cry out in surprise and alarm just before the door to her bathroom slammed into her nose. Being a functionally immortal goddess with decades of training and battle under her proverbial belt, the blow stunned her more than her hurt her.

Okay, fine. It actually hurt a lot and practically made her jump out of her skin.

Backing up a few feet and holding a hoof to her slightly bruised nose, Celestia called through the door, “Twilight?” her voice coming out slightly muffled.

The was a few seconds of silence followed by a hesitant, “…Princess Celestia?”

“The one and only,” Celestia replied, removing her hoof from her nose. “Is that you, Twilight?”

“…Yeah,” came the reply through the door.

“Twilight, what are you doing in there?”

“Nothing,” came the very weak reply. Not weak as in faint, but rather in the sense of a bad lie.

“Twilight, I’m coming in,” Celestia said, turning the knob on the door.

There was some resistance at first, but that quickly stopped, likely because it really was futile. Celestia swung open the door to reveal Twilight standing near the sink, wrapped in a towel, and looking ashamed. The door to the medicine cabinet was open and a few of its contents had been removed, most now laying in a small pile in the sink.

One bottle, however, lay at Twilight’s towel covered hooves.

The purple unicorn opened her mouth to explain, but whatever explanation was coming died in her throat and the bottle was surrounded by Celestia’s magical field.

“Wait!” she said, sounding near panicked.

Celestia ignored her for the moment as she brought the bottle close enough to read the words on the front.

“‘Madam Marevelous’ All-Purpose Lubricant’.” Celestia read aloud, shifting the bottle to the side so she could peer inquisitively at Twilight. “Why were you trying to get this, my faithful student?”

Twilight’s mouth opened and closed several times, her face so red it might have become permanent. Eventually, after several moments of silent mouth flapping, she croaked out, “I was just curious.”

Celestia raised an eyebrow. “Curious? About lubricants?” Celestia chuckled in her motherly way as she set the bottle on the sink counter. “You could have asked, my faithful student.”

Twilight averted her eyes. “You would have wanted to know why.”

Celestia lowered her head so it was level with Twilight’s. “Of course; I always take interest in your little experiments.”

“Irony,” Twilight said under her breath.

“What was that?” Celestia asked sweetly, despite the fact she had heard Twilight quite clearly.

“It’s not important,” Twilight said quickly, making to leave. “I’ll just… go to the library and do this later.”

Celestia blocked her path, keeping her gentle smile in place. “With my towel?”

Twilight looked panicked again. “Well, uh, you’re not using it right now.”

“I was planning on a bath.”

“You have other towels,” Twilight said, trying to edge her way around Celestia’s leg.

“Ah, but that one is my favorite.” Celestia kept smiling as she closed the door with her magic, just in case Twilight dared a mad dash between her legs. “Now why don’t we calm down and explain ourselves?”

Twilight looked forlornly at the closed door for a moment before backing up a few paces from Celestia. “Princess,” Twilight began unsteadily, Celestia simply smiling reassuringly and waiting.

After a few seconds too many of silence, Twilight took a deep breath and started again. “Princess, I have a rather… unique condition I haven’t told you about before.”

Celestia tilted her head. “You do?”

The unicorn nodded. “It’s… very embarrassing.”

Celestia gave Twilight her best comforting smile. “You have nothing to be embarrassed about with me, Twilight.”

Twilight nodded and then opened her mouth to continue speaking. After a moment devoid of silence, she closed her mouth and simply let the towel fall.

Among the things Celestia expected to be hidden by the towel ranged from porn magazines to anatomy books to, stars forbid, one of her own ‘late-night assistants’. So her look of surprise was warranted when she found herself looking at a healthy pink horse phallus, currently attached to her faithful student.

Celestia initially assumed it was a strap-on, which of course made her wonder who exactly Twilight planned to use the thing on, but the longer she looked at it, the more apparent it became that it was actually a real, physical penis attached to Twilight.

The infinitely awkward silence that followed was broken by a tentative, “…Princess?”

It was only after this that Celestia realized she had begun to drool. With a hasty swipe of the tongue and a ‘slurp’ that was louder than she liked, Celestia cleaned up the drool and covered her embarrassment with a large and nervous smile.

“Ah, I, uh, see what might be the problem,” Celestia said nervously.

“I kind of tried a spell I shouldn’t have,” Twilight admitted, looking away. “A-and now I can’t get it to go away!”

“Really?” Celestia said, leaning down the get a better look at the phallus before her, trying to keep her expression detached.

“The counter-spell didn’t work. A-and the book said that it should go away after I, um…” Twilight trailed off, blushing heavily.

“Climax?” Celestia offered, admiring the size of the magically induced organ while trying to look like she wasn’t doing anything of the sort. It had to be at least ten inches long and an inch and a half thick. The flare at the tip was probably two inches, if not more.

Twilight nodded. “B-but it said I had to-to cl-climax three times!”

“Hence the lube?” Celestia asked with a smile, raising her gaze to look at Twilight’s face.

“Y-yeah,” Twilight said, cheeks aflame.

“You should have just asked me for help,” Celestia said in a low and husky tone.

“I should have asked- ? Eep!”

Twilight made the cutest noise when Celestia’s tongue made a swipe along the flare of her cock. The phallus suddenly shot up to full hardness, Twilight’s embarrassment likely having kept it, heh, ‘half-cocked’ before.

“Princess!?” Twilight cried out while backing up, only to quickly run into the side of the tub.

“You obviously could use some help, Twilight,” Celestia said, her smile salacious and anything but motherly. “Allow me.”

Any more protests from Twilight were drowned by the throaty moan that she gave as Celestia took her flare and first few inches into her mouth. Twilight’s cock was warm in her muzzle and tasted clean and meaty on her tongue. The alicorn took her time to properly work the organ over in her muzzle, lathering what she had taken in her saliva.

The sounds Twilight was making alternated between adorable, breathy gasps and deeper grunts, with the occasional moan mixed in. It was music to Celestia’s ears. Long had she wanted intimacy like this with her Twilight, although it had never quite worked out this way in her head.

Finally, after who knows how long, Celestia freed Twilight’s cock from her mouth, leaving the unicorn panting, but still rock-hard and throbbing. Noisily licking her chops, Celestia laid herself down on the marble floor of the bathroom, scooting herself a little closer to where Twilight was propped up against the edge of the tub.

Celestia brought a hoof to Twilight’s cock, pushing it gently until it flopped to the other side, admiring how the saliva-soaked end glistened in the light. She continued to grin as she dropped her head lower, noting how the unicorn’s breathing became faster as her nose bumped the base of her shaft. This brought a delighted giggle from Celestia, as did the sizable pair of testicles Twilight also sported.

Celestia gave each testicle a long, loving lick with her tongue, eliciting more gasps from Twilight, before beginning to move up the shaft, slathering it with saliva. Celestia was careful; she knew these sensations were new to Dear Twilight, and she didn’t want the unicorn blowing her load just yet.

Eventually, Celestia was back at the top, circling Twilight’s flare with the tip of her tongue.

“…Pr-princess?” Twilight managed to get out.

“Hm?” Celestia replied, not stopping her tongue swirling.

“C-could you-” Twilight gulped nervously “-could you t-take, ah, it d-deeper?”

Celestia slurped her tongue back into her mouth, swearing she heard Twilight groan in disappointment, and gave the unicorn another lusty grin.

“And how much deeper would you like it, my faithful student?” Celestia asked, holding her head up with a hoof.

Twilight avoided eye contact as she said in a quiet voice, “All the way down.”

Celestia didn’t answer. Instead, she lined Twilight’s flare up with her mouth, quickly scooping it in with her tongue. The alicorn slid her lips down the shaft until the head rested on the back of her throat. She took a few quick breaths around the cock before lunging her head forward, surprising both herself and Twilight as she took the entirety of the unicorn’s length in a single swallow.

While this was a something of a victory for Celestia, her gag reflex was rather unhappy with it. Her throat squeezed down on the intruder, which only served to turn Twilight’s gasping moan into a throaty cry of climax. Celestia felt the shaft pulse in her throat as it deposited a hot load of cum into her belly. But as nice as that was, she was still choking.

She hurriedly pulled herself off Twilight’s cock, catching half of the next spurt in her mouth and the rest on her face. The third and final spurt of spunk was less powerful than the ones before, and only managed to catch the tip of Celestia’s chin before splattering her neck and chest.

Twilight let out a happy, airy groan as she fell over sideways, the aftershock of her orgasm still working its way through her system. Celestia occupied herself with enjoying the still-warm cum in her mouth, allowing it to properly soak into her taste buds before swallowing it down.

The alicorn once again noisily licked her chops as she stood up, using her magic to collect the cum soaking into her fur.

“Princess…” Twilight croaked from the floor as Celestia gathered up all the cum into a floating sphere before her before promptly scooping it in with her tongue and swallowing it down.

“Come on, Twilight,” Celestia panted, feeling her own arousal running down her thighs as she helped the wobbling unicorn to her hooves. “We still have two more to go.” she opened the bathroom door and began to walk out. “Oh, and grab the lube, if you will.”

Twilight nodded and reached for the lube and

Celestia grunted through clenched teeth as she came, her juices soaking her hoof and the seat of her chair.

She’d been writing with one hoof the past few minutes or so, not trusting her magic to keep the quill steady. Finally there was no point and she dropped the quill as her climax rippled through her. The alicorn screwed her eyes shut and clenched her jaw harder, trying to be as quiet as possible.

The spells that kept the noise in her chambers from reaching the outside halls had a charm woven in that allowed sounds of certain volume to escape. This was so that if an assassin were to somehow corner her, the guards could hear her scream. But it also made keeping her pleasure private problematic.

Finally, after what seemed like an eternity of riding the stormy waves of pleasure coursing through her, Celestia’s orgasm tapered off, leaving her sweating, panting, and her thighs soaked. She was leaning back in her chair, noting how the slightest movement brought a soft squelch or squeak to her ears.

After a while of simply staying like that, she leaned forward to read over what she had written, ignoring the cooling mare-cum soaking her seat for the moment. While her quillmareship had gotten a little frantic and less neat near the end, this little foray had brought her better satisfaction than the other one. Granted, this was far more ridiculous, but Celestia could forgive that; this had certainly been more productive.

It still wasn’t real and it still had been nothing more than masturbation, but Celestia did feel better.

The alicorn stifled a yawn and glanced at the large clock on the wall. Well past midnight. She cleaned the quill of ink and placed it back in the jar with its fellows, putting the stopper in the inkwell before setting that aside as well. She hesitated as she regarded the few sheets of parchment she had written on. Should she burn these too, to hide the evidence?

After a small shake of the head, Celestia rolled the sheets up and tucked them away in a drawer, locking it securely by both magical and mundane means.

She rose from her seat, the cushion still slick with her juices, and used a quick spell to clean up the mess. Satisfied that both she and the chair were clean and dry, Celestia doused the various lights that kept her room lit and slid beneath the covers of her bed.

She had planned on just laying there in the dark, thinking up some way to put this madness of hers to rest without doing any permanent damage. But, as soon as she moved into a comfortable position, she was snoozing away. Her dreams, however, were not free of a mischievous and tempting purple unicorn.
