Spring.
Spring at Celestia's School for Gifted Unicorns always meant a few things.
First, it meant the school year would be over soon, and students were discussing their summer plans. Vacations, camps, jobs.
Certain students were beginning to worry about exams, even though exams were over a month off. Needless to say, by "certain students," that means "Twilight Sparkle." Because who else could worry about exams a month out?
This pre-Ponyville Twilight was already very much the Twilight we would eventually learn to love, so it's no surprise that she spent that spring how she spent every season, buried in the library, studying her brains into something that resembled mashed potatoes, forgetting to eat, forgetting to exercise, forgetting to bathe.
Spring.
Spring also meant something else, for the students Twilight's age.
It meant the female students in her grade were getting their first estrus. Unicorns entered estrus much later than earth ponies or pegasi, but when it hit, it hit that much harder.
Lemon Hearts was the first, and as her pheromones infused the tightly-packed female dorm, the rest of them followed her like dominoes into hormonal lunacy. Twilight, although socially stunted, was a perfectly healthy example of unicornkind, and her first heat hit strong and hard, like a violent buck right beneath her tail.
Being Twilight, she dealt with this by going to the library, grabbing some books on advanced calculus, and reading.
She sat on a towel, because she was leaving wet spots everywhere, and that was embarrassing, especially when Spike had offered fetch some diapers from the store.
All things considered, this was expected: mother had explained, a year or two back, that unicorns have wetter heats and gushier orgasms than the other tribes of pony, a side effect of clamping down on your magic to keep the sensations from coming out your horn. It was a small price to pay for all the good aspects of being a unicorn.
...or was it? More fiery liquid dribbled from between her thighs. After finishing this calculus book, she would find an anatomy book, and determine which gland was producing all that liquid. She didn't think it was pee, but she wanted to be sure. And if it was magically summoned, there might be a magical way to eliminate it....
Twilight concentrated on her book, grinding her teeth, and tried to ignore this fresh Tartarus deep in her guts.
She also planned to have Spike bring her a dry towel, if she saw him.
She would not explain to Spike why.
Spring.
Spring at Celestia's school.
The school nurse and the school chef de cuisine, working together, increased the doses of birth control potion in the cafeteria food, and the school nurse and the facilities engineer increased the doses of birth control potion in the water supply.
Celestia sniffed the pheremones in the air and suggested further increasing the dosage.
Spring.
Spring at Celestia's School.
As hard as the Twilight and her friends were having it in their dorm, the young stallions had it worse. They had to smell the estrus hormones pungently wafting from the female dorm.... while there was nothing they could do.
Azure Almonds, the lone unicorn offspring a large earth pony family, sat at a study desk in the dorm, trying to read his History of Magic book.
It wasn't working.
Two years before, the school nurse had referred him to a dentist in Canterlot to get an abscessed tooth drilled out of his skull. The tooth had burned, throbbed, flared, flamed in his jaw before he finally went to the nurse with the problem.
His privates presently nagged him the same as that tooth had, but no dentist or nurse was going to be able to help with this agony.
The locker room was replete with the sound of clopping in the toilet stalls, and the plumber was coming in twice a day to clear the shower drains.
Azure Almonds, however, was not going to clop.
No, he intended to get laid.
And, because he hadn't clopped, getting laid. Would. Be. Bucking. Epic.
The problem, he admitted, was that he didn't know how to get laid. The gals liked him well enough, with his gray eyes, muscles from growing up among earth pony siblings, and the bright white blaze on his muzzle, but 'liked him well enough' was a far cry from getting up inside one of their snatches.
His first hope was Lyra--far and away, the hottest in his grade--but she was into mares. Minuette and Twinkleshine were also hot, and Amethyst Star or Lemon Hearts would do.
Heck, he just wanted to get his willy wet. Even one of the weird ones like Moon Dancer or Twilight Sparkle could handle that. He wasn't picky.
He tapped a hoof on his chin. He didn't know how to get laid. But he could find out. This was a school, after all. Maybe there would be a book?
He stood up from the study desk. Cock flopping out of its sheath as he walked, his balls swollen and pendulously swinging, hurting every time they slapped against his inner thighs, he headed to the library.
Twilight realized that, for the last seven minutes and twelve seconds, she had not actually been reading the advanced calculus book.
She'd been staring at an illustration.
An illustration of a handsome pegasus stallion standing in front of a lecture hall, waving a wing at a chalkboard.
The caption read, Lightning Integrator demonstrates the Fundamental Theorem of Calculus to his students at Cloudsdale College, year 242.
Pegasi.... she'd only met a hooffull of pegasi in her entire life. ...what did their feathers feel like? Feathers, running up and down her spine, ohhhh.... Other than a hoof shake, she'd never even touched a pegasus. "He could integrate me any time...." she whispered, rocking on her chair, rubbing her swollen nethers against the sopping wet towel, and then clapped her hooves over her mouth and looked around.
"Pardon?" said another student, standing about twenty feet away and browsing the self-help books.
He was pale blue, a shade darker than the sky, with a black mane and tail, and a white blaze on his nose and white sock markings on his lower legs.
This pony was in some of her classes. His torso faced away from her, tail toward Twilight, and he looked over his shoulder.
"You said something about..." he smiled "...integration, Twilight?"
Uh-oh. He knew her name. What was his name? Think, Twilight, think.
Twilight didn't like him. She remembered that, for one hundred percent sure. But why....?
Oh, right. He and Twilight shared the exact same birthday, she a few hours his elder, so the dorm always had a combined ice cream and cake party for Twilight and what's-his-name every year, ever since magic kindergarten.
If it had been her birthday alone, she could have begged off the irksome party once a year, and spent more time studying.
What-was-his-name?!?
She couldn't think. The stupid estrus hormones filling her bloodstream were impairing her higher cognitive functions, and the ache, the ache in her groin was so distracting, and oh sweet Celestia oh no oh no oh for hoof's sake his male genitals were hanging out!
His.... penis... was mostly erect and hanging under his belly, and his scrotum and... and... and testicles were distended, hanging down, swaying slightly, throbbing.
She squeezed her eyes shut.
Okay, it wasn't like she'd never seen a pony with a hardon before. Hardons happened, especially at their age. The polite thing was to ignore it. Everypony ignored the hardons, and ignored the girl's puddles. The was just what was done. In polite society.
Her towel was entirely soaked, and she could smell herself. No doubt he could smell her, too. She faced back down at her book and opened her eyes again.
The urge to stand up and run back to the dorm, climb into her bed, slip under the covers, and masturbate wantonly nearly overwhelmed her.
But that exact plan had worked so poorly yesterday...
She couldn't get up. Her juices soaked her entire backside. She probably looked like she had peed herself. (Which she had not!) Twilight needed to sit there and dry off for a little while.
Except, of course, she was getting wetter, not drier, by the minute.
She levitated her water bottle out of her bag and took three long swigs. No need to risk dehydration. Moon Dancer had found herself in the nurse's office on an IV exactly that way.
(The nurse, kindly, had said: "I get a half dozen of these every year.")
Today, Twilight decided, her mare parts pained her even worse than yesterday--and yesterday had been the strongest, and most embarrassing, day of her estrus so far.
Her labia were swollen and throbbed with every beat of her heart, and her clitoris rubbed against the towel. She'd borrowed the towel from Lyra, because it was softer than anything Twilight owned, but it still rubbed her winking, protruding clit raw. She shifted her weight and pulled her rear legs up onto the chair a little more, trying to get her weight off her loins, but as soon as she did that, the cool air hit her sopping wet privates and sent a chill up her spine, where it settled into her chest, just above her sternum... and clashed with the molten metal swirling in her lower abdomen, around her uterus and ovaries.
And, Twilight thought with a frown, darn you Lyra! Lyra had a steady fillyfriend one year older than her, and those two were handling each other's heat, so Lyra wasn't nearly as bonkers as the rest of them, and it wasn't fair!
Hooves shuffled against carpet as he moved a few inches left, selecting a different book. Twilight shifted her eyes and saw his.... ahem. His testicles were really swollen inside his blue scrotum, and throbbed with his heartbeat.
Azure Almonds. That was his name!
With a frown, she thought, His almonds most certainly are a shade of azure.
Azure's nose burned as Twilight's pheromones swirled in the corner of the library. He could see the puddle she was sitting in, the mint-green towel (likely stolen from Lyra) soaked to a dark forest green. Luckily it was a varnished wood chair, and not upholstered. It would be easy to sanitize.
Twilight's body odor also filled the area. Sweaty, a bit ripe--she was famous for spending more time studying than showering. Boinking her would not be the same accomplishment in the eyes of the others as, say, boinking Minuette (a total eight-point-five out of ten, agreed the entire male dorm), but.... pussy was pussy, Azure decided, and if he didn't get off today he was sure his balls would detonate and geld him. So the heck with what the others thought. Besides, the intoxicating scent of her heat outweighed the icky smell of her mane and sweat.
So. He would attempt to boink Twilight, and if that failed, he would admit defeat, head to the locker room, and clop in a toilet stall.
But how? How to boink Twilight? Everypony knew she only loved books....
Idea!
Oh, thank Celestia. Azure wandered away, leaving Twilight in peace. She looked at the handsome, handsome pegasus stallion in the book's illustration. After about a minute of staring she whispered, "Fundamental theorem of Calculus? No, the fundamental theorem of sex..." and reached her left hoof down toward her tail.
Okay. Okay. He could do this. Easy. Twilight loves libraries. So. So. Just....
...make like a library. No, there was no way he could do this. How is a unicorn supposed to be like a library?
He wandered down the next rank of books and heard a desperate whisper: "Fundamental theorem of Calculus? No, the fundamental theorem of sex..."
Peering through the bookshelf, he saw Twilight's ears perk forward, and a hoof dipped away from the book, under the table, down toward her....
Oh. Oh! This was his chance. She was rubbing off. Prudish, bookworm, princess's pet, rules-follower Twilight Sparkle was rubbing off in public. This was a golden opportunity. Think fast.
He grabbed the oldest looking book on the shelf and opened it. The edges of the pages were crumbly, breaking down into musty-smelling dust.
He levitated the book up, and rubbed it all over his mane and cheeks and neck.
Then, just to be sure, he levitated it down and rubbed it on his cock and balls.
He now smelled like old library. Little bits of old paper clung to him. That had to help, right?
He sneezed.
A quick peer through the bookshelf showed Twilight hadn't noticed his sneeze, and was still bearing down on her own nether regions, muttering about calculus and pegasi.
Darn. Darn. Peagsi? Did she have feather fever? Every male in the school was a unicorn, which could explain why she wasn't already getting her heat quenched.
There was no way he was getting wings--real, prosthetic, or costume--in the next few minutes, so just move on, and hope her feather fever was a preference and not an immutable desire.
Okay, how to be a library?
He trotted to the reference section (cock and almonds slapping painfully as he went), and found Bucklett's Quotations.
Flipped to the index.
L.
L-I-B.
Libraries. Perfect.
Twilight shuddered, gave a little squeak in the back of her throat, clamped against a rogue spell before it could light up her horn, and a gush of hot liquid squirted from her nethers and soaked her left fetlock. The smell of her own masturbation hovered around her, and her ears wilted as she pondered the embarrassment potential should Princess Celestia or one of the librarians wander through.
Did alicorns go through heat? Would The Princess understand? Well, Cadance certainly had heats.... poor Shining Armor....
Twilight's hormones were simply out of control and she didn't know what to do. Her dock and upper tail were soaked, the wetness coating her own anus, making it feel slick and weird. Yuck, yuck, yuck. Everypony knew the first heat was supposed to be the worst, but going through even a fraction of this a few times a year for her entire adult life... yuck. Maybe a hysterectomy was in order, so that this didn't interfere with her studies for life.
She could grab Spike and trot home--her parents lived slightly less than an hour's trot away, right here in Canterlot--and take a few days sick in her own room. Mom and dad would understand. Of course, trotting down public streets with her tail and bottom sopping wet would be all kinds of embarrassing...
As she lifted her hoof away from her clit, she realized that for all the fantasizing and masturbating, all the attempts at release, the grinding, roiling, flaming agony in her abdomen and loins was getting worse not better.
Stupid evolutionary imperatives. She knew about sex. All about it. Got the lecture from her mom. Read a dozen books. Heck, more like a dozen dozen. In years past, Twilight had cast scrying spells and seen her parents make love, and watched her brother and the foalsitter, Cadance, together. She learned a lot that way. Specifically, she learned she didn't want to have sex. It seemed... messy. Icky. Squelchy. Time consuming, time away from her studies.
Not her kind of thing.
Sex seemed too personal, and Twilight was more comfortable with books than with other ponies. She didn't want to be close to a pony, especially not an icky colt or stallion who just wanted to get his own release from his own throbbing agonizing nethers.
Oh. Oh! Oh, yuck: if she had sex, should would drip... semen... from her vagina for hours, or a whole day. Oh yuck. Yuck! Her own juices were icky enough!
She bent her head way down, pursed her lips, and blew on her clit and labia, trying to dry and cool them off.
It didn't work.
She took in a deep breath, to blow harder, and--
"Hey, Twilight?"
She jerked her head straight up and her ears twisted in different directions. "What! What! You're interrupting my studying, Azure Almonds!"
He grinned, very slightly. "It looked like you were studying your own.... belly."
Twilight's eyes widened and fire swelled under her cheeks. She tapped the tabletop with her right forehoof and kept her left foreleg--still soaking wet from her own pussy spew--hidden beneath the table.
Azure Almonds stood there, and Twilight sniffed, smelling something different... but familiar, and nice... coming from him. Something comforting.
He smelled like old books.
His penis was still throbbing underneath his barrel. She looked away from it, looking at his face. She stared at the white blaze between his gray eyes. Few ponies had blaze and sock markings. It was more common than, say, prismatic manes, but still quite rare.
She didn't find it attractive, but it was something to stare at that wasn't his throbbing cock.
He levitated a heavy book and dropped it on her study table with a thunk. "You spend a lot of time here in the library, Twilight."
She sniffed. "This school is expensive, and my parents pay a lot of money. I want to make the most of it."
"I think I understand why, now, you like the library so much."
"I'm trying to bone up on calculus," she snapped.
"Bone up, eh? Can I help?"
"You're still in algebra."
He blinked. "Well, that is the syllabus, for the rest of us."
Twilight's left foreleg inched towards her clit again, and ground her teeth as she forced it away. "What. Do. You. Want. Almonds?"
He looked at the book and read, "'The library is the temple of learning, and learning has liberated more ponies than all the wars in history.'"
Twilight's eyes widened and her stomach turned sour.
"'A library is not a luxury but one of the necessities of life,'" he read.
Fresh juices poured down her labia and coated her anus and dock again.
"'I discovered me in the library. I went to find me in the library.'"
"Please stop," Twilight said, as her clit and asshole clenched in time with the throbs in her lower belly.
"What?" Azure's face wrinkled and his ears wilted. "I thought you liked libraries? I'm trying to understand why you like them so much, and I think it's working. You're a good example, Twilight. I don't get grades like you. My parents pay a lot of money for this school, too, and I want to make the most of it. I can learn from you."
She nodded, curtly, and let her left forehoof--hidden under the table--begin to play up and down her pussy lips.
"'Your library is your portrait.' I guess they mean your personal collection, rather than the library you go to."
She looked up at him, and began to rub her clit harder. She knew the motion in her shoulder would be visible to him, but there was nothing she could do. "Azure. I'm not feeling well. I might... uh... go back to my dorm and take a little shut-eye."
"Of course, sorry I bothered you." He smiled, and levitated the book closed.
As her left hoof ground against her clit, Twilight's right forehoof reached across, to her left armpit, just below where it met her barrel, and felt to verify that the crystal implant was still there, under her skin, where it had been for two years now.
Not that she needed the magical implant. She wasn't going to have sex. Not today. Not tomorrow. Not ever. It was silly of her parents to have made her get a birth control crystal. Why was she rubbing it, anyway, while she rubbed her clit at the same time? That didn't make sense. She wouldn't have sex. She was in control.
Stupid parents. Stupid birth control implant. Stupid estrus. Stupid colts.
A powerful squirt of liquid gushed from nether regions, and struck the carpet with an audible splat.
His ears perked forward. His nostrils flared as he sniffed.
She stared at his throbbing cock. She had no idea if it was small, medium, large. She had no basis for comparison. She had no idea. But, she knew, knew, it was the smell of her estrus pheromones here in the library that were making it throb.
She had made him erect. That was a.... strange... feeling.
Nopony had ever paid her any mind before. Twilight was... an egghead. She never exercised. She hardly ate. She knew she was scrawny. Lyra, with her jaunty mane, lean muscles, musical genius, and pastel colors, drove the guys crazy, especially because they knew Lyra liked other fillies, and was forever out of reach. A lot of them liked liked pale--opposite to Twilight--and Twinkleshine had lost her virginity moons ago, well before she ever came near estrus, and they chased her constantly.
Twilight was just.... Twilight.
And despite being just Twilight... she was giving somepony a throbbing hardon.
Vagina to Brain, she heard in the back of her mind, I'd really like to know what that thing feels like. Getting curious down here.
She lowered her head to look at her nethers, a tiny smile spreading across her face.
Anus to Brain, leave me out of this. Call me on our first wedding anniversary.
Brain here, messages received and understood.
She clenched her eyes and bore down on her clit with both forehooves. Her tongue stuck out a fraction of and inch and she bit it.
A checklist. She needed a checklist. Where was a scroll? Her quill and ink? Step one: don't have sex. Two: see step one. Three: see step two.
Step four: verify birth control implant.
Step four: Check!
No. No step four.
Step five: give somepony a throbbing erection.
No! No! None of that! Don't think that!
"I memorized one quote," he said. "I like it a lot."
Twilight nodded and said, "hnnnnnnrrrk."
"It went, 'A library book, I imagine, is a happy book.'" Then he nosed open the large book's back cover, levitated out its catalog card, licked the back of the card, and slapped it to his blaze.
"Now, I am a happy book." He smiled at her.
Wonderful parents. Wonderful, reassuring birth control implant. Wonderful estrus. Wonderful colts.
Twilight smiled up at him. She was going to screw his balls clean off.
She opened her eyes and leapt onto the table, chair and sopping towel flying backwards. With a perfect four point landing, she hit the center of the table, and then pronked off the table, tackling him. He landed flat on his back and all his wind huffffed out of his lungs under her weight. The catalog card flew away.
She slammed her soaking wet hips onto the middle of his belly, just below the ribs, leaned over, and gripped his left ear in her teeth and gave a pull.
The ear-bite-and-pull was something Twilight had seen Shining Armor do to Cadance, and Cadance always howled in delight. Oh, how mad those two would be if they knew Twilight had scryed on them.......
She tasted the fur of his ear, and adjusted her bite ever so slightly. Azure's mane tickled her nose and he smelled like a book oh Celestia he smelled like a wonderful, old, musty book. The tip of his penis was pushing against her spine, right above the tail. A spasm ripped across her bottom and her loins and she ground her sopping wet marehood across his barrel and bit down harder on his ear. He yelped, and she tasted his blood as her teeth broke his skin.
"Remember first-day orientation this year?" Twilight asked, releasing his ear, which was actually bleeding pretty well, now. Oh. Oh! Oh goodness. He was going to need stitches.
"No!" he said.
"I consent. Do you consent? Celestia was really, really insistent on consent."
"Yes yes yes! I consent! Is my ear bleeding? That hurt, Twilight."
"Don't ruin this. We'll get you stitches later."
"I need stitches?"
"Don't ruin my first time!"
She spit out some of his blood, and wiped her face with her left hoof. On her hoof, she tasted... herself. With a quick lick, she sampled her own juices on her forehoof again, and an idea formed. "If you ejaculate before I break my heat, I'll buck you in the testicles and teleport you to the moon! Perform cunnilingus!"
"What? Twilight, you use crazy-big words."
"Eat my fillybits!"
"Oh! Oh! Heck, yes!"
She rolled off him--oh Celestia there was a bloodstain spreading on the carpet from his ear--shifted herself around a half-turn, planted her rear legs on either side of his head, and plopped her nethers right down onto his face.
"Mmmmrrrrrrrpppphhhhhhh!!!!!"
His levitation lifted her bottom up and he gasped. "Leave some weight on the floor, Twilight, or you'll smother me!"
She flexed her legs and lowered herself to his face, more carefully.
His tongue traced between her lips, and Twilight's entire world changed forever.
A lightning bolt shot cross her hips, down her legs to the floor, and made her tail flag straight up, exposing her anus to the world as it clenched tight. Branches of lightning circled around her ribs and settled into her belly and the muscles around her uterus spasmed in surprise. The wonderful sensation ran up her spine, into her head, and her other lips quivered and she drooled, dripping saliva onto the puddle of her own fluids on his belly.
And then he did it again!
Planting her forehooves on the carpet, on either side of his hips, she took ragged gasps in time with his licks. Her clit winked, protruding out, as if it was chasing his tongue, but he wasn't licking it, he wasn't licking it, he was teasing her, her butt muscles clenched with every contraction of her pussylips, and her vision grayed as blood rushed away from her head.
"Oh sweet Celestia for the love of the moon and the stars lick my clit!"
Upon hearing her name wafting across the stacks, Celestia slipped off her formal metal shoes and began sneaking across the carpeted floor of the library. She let her sensitive alicorn nose guide her.
Somepony was really deep into estrus.
Egads, she got tired of dealing with this every spring for the last eight centuries.
Staring, Twilight realized Azure's throbbing privates were only a few inches from her own nose. She leaned down and sniffed.
His privates smelled like books, too! Her horn tingled with a building magical discharge, and she clenched down on it, squelching the spell, and the magic rebounded down her spine and out her vagina.
"Gaaack!" he gasped, spluttering, coughing, as the huge squirt shot from her nethers and splashed his face, going up his nose. "Twilight! Did you just pee on me?"
"No! That was just a really gushy orgasm."
"That was, like, a pint."
"Don't stop licking! Gushy orgasms are what happens."
Azure licked her pussy lips, up-and-down, and said, "Are you sure?"
"We're unicorns, unicorn mares and fillies gush. It's the magic. It's gush or blow holes in the wall with our horns. I choose gush."
"What?"
"Didn't your parents teach you anything before they sent you off to boarding school?"
"No!"
"What are they, earth ponies?!?"
"Yes! And stop talking about my parents during sex." He licked her, slow and deep again.
Twilight intercepted another spell just before it could manifest and scorch the ceiling, but she sprayed another gush of hot fluids across his face.
"You're absolutely sure?"
"If you don't like it, go back to your dorm and clop."
He licked down her lips, toward the back of her slit, and her butthole clenched at his proximity.
"Don't stop, Almonds!" Twilight lowered her weight just... a... little... more... and his tongue began to explore up into her vagina, parting her lips, and the lighting bolts up her spine, encircling her hips and belly, and hitting her head, intensified.
She leaned down and touched the tip of her tongue to the tip of his penis.
He tasted like old books. She spurted onto his face again, and he dug in even deeper with his tongue.
(She was getting dehydrated. She needed to drink a lot of water once they were done. Post-sex checklist, item one: drink.)
Twilight's tongue licked up the right side of his cock, from the base to the tip, over the top, and then back down to the base on the other side. She closed her eyes and rode his tongue-fucking for a few seconds, and then made an O with her lips and gently pulled the first half-inch or so of his tip into her mouth.
He moaned into her snatch, and the vibrations changed the rhythm of the lightning bolts running from her asshole up to the tip of her horn. She licked her tongue across the slit at the tip of his cock.
For a split second, her brain rebelled: That's where pee comes out!
The clenching in her ass and abdomen replied, He's half-drowned on our squirts! Let's be a team player! She started flicking her tongue around his tip, while massaging with her lips.
"Hey, Twilight?" he gasped.
"Don't stop to talk!"
"Don't play with my tip, if you want me to last."
She sat up, and looked over her withers at his horn and the top of his head, which were mostly covered by her tail. Her tail was stingy and soaking wet. "But... what do I do?"
"Suck my balls?"
She leaned down.
Celestia grinned and shook her head at the noises coming from somewhere ahead of her. Students. Students never changed. In the centuries she had run this school, every spring played out the same way.
Celestia recalled the desperately rushed research to invent birth control spells, the first year she ran the school.
Walking more slowly and quietly, ears rotating to fix the squelchy noises, Celestia continued sneaking toward the students, preparing a lesson in discretion and in what should be done behind closed doors.
A small sleet storm--good, old-fashioned, freezing-cold pegasus magic--usually ended a session of public lovemaking most effectively.
Twilight nosed his erect cock to the side, and found her nose touching his ballsack.
He clenched when the velvety softness of her nose touched him, and his tail slapped against the floor.
Yes, his scrotum was blue.
And throbbing.
And swollen.
She rubbed her snout against it and his entire body spasmed beneath her.
The scientific part of her brain--the little bit that wasn't fogged under a haze of hormones and the clenching in her vagina and asshole--said, His ejaculation is going to be extremely large, and you don't have a dry towel.
Good, she told herself. A lot of drippy spunk might cool off my heat.
Her tongue reached out, and caressed his left testicle. There was a bit of a sweaty taste, but not too bad. He moaned into her pussy again, and she shifted her head an inch, and began to lick up and down between his balls. His cock started throbbing against her cheek even harder, and his tail smacked the floor in time with her licks.
With a smile, Twilight realized, He's enjoying this!
She pulled his right ball entirely into her mouth.
"Ohhhh.... wow, Twilight, that feels great!"
And then he shifted his head, and he tongued her clit for the first time right at the... exact... moment... it winked out at him.
Celestia peeked over the bookshelf and recognized Twilight Sparkle instantly. It also impressed her that Azure Almonds, of all ponies, was the one whose face Twilight was sitting on. Azure wasn't as asocial as Twilight, but he wasn't a Cassanova, either.
As much as she wanted to ice them, levitate them both up, and give them a stern lecture and several days' detention...
...Twilight needed a good rutting more than she needed a lesson in discretion.
Celestia frowned. Azure's ear was bleeding freely, and a good-sized puddle of blood spread underneath the two lovers.
The princess hunkered down and looked through the books, ready to intervene if Twilight hurt him worse, or in case her orgasms started manifesting through her horn. Celestia prepared a shield spell, just in case. Twilight was fully capable of blowing a hole in the ceiling and injuring somepony on the second, or even third and fourth, floors.
Given that Azure's face was soaked like somepony just out of a swimming pool, it seemed likely that Twilight had already taught herself to be a pussy-squirter, not a spell-spurter.
Thank goodness for small favors, hmmm? Twilight truly was an excellent student.
Azure's lips clamped around Twilight's clit, and his tongue began to massage it.
Her entire body lit up, from tail to horn. Her ass clenched, her pussy squelched more fluids onto his face, her ears went totally erect, and her spine straightened.
That straightening led to her lurching upwards, his right ball rebounding out of her mouth with a loud pop!
His body jerked and he yelled, releasing the pressure on her clit. "Ow! Twilight, that hurt! Be careful down there!"
She rolled off him and turned herself around again, head-to-head and tail-to-tail with him. "Intercourse."
"My ball really hurts, Twilight."
"Do you want your penis in my vagina?"
"Yes! Shouldn't you get down on all fours and present? Isn't that how this works? That was in health class."
"No," Twilight said, crawling onto him to straddle across his hips, facing toward him. She grabbed his shaft in her levitation and brought his tip just to her pussylips. As it touched her for the first time, she spurted again, and sprayed pussyjuice all over him, soaking his cock. He moaned happily.
"This is my first time," Twilight explained. "I want to control the speed and depth. Let me take lead, and be as gentle and as slow as I need."
"Oh. Okay."
She slammed her hips down with all her strength.
Celestia's eyes widened and Twilight brutally impaled herself on him. His scrotum was swelling and blackening, but the young idiot was too enraptured by the estrus hormones coating his muzzle and nasal passages to realize he needed a trip to the nurse.
Well, Celestia decided, letting those two finish and release their mutual hormonal pressure cookers could only make the nurse's job easier. No need to try to ice fully-charged testicles, hmmm?
Celestia frowned, feeling a wet sensation under her own tail, and decided she would need to call Fleur-de-Lis to an "appointment" in her Royal Chambers tonight, herself...
Twilight hilted him, dropping her entire weight across his hips.
"Yeeep!" he said. "Wait, didn't that hurt?"
Sweat broke out across Twilight as he filled her up. "Nope! Felt.... oh, good..."
"Wait--you're sure this is your first? That's fine, I don't care, but you just hilted me."
"First... uh, penis in me, yes." She squirmed, trying to get another fraction of an inch insertion, and his tip hit her cervix. "Oh! That's.... unpleasant..."
"What?" Azure frowned.
"I went too deep," she said, and lifted herself up, until her lips barely held him aligned, and then lowered herself gently.
His back arched, and he sucked in a deep breath. "Oh.... Celestia, you're so warm... and wet..."
She placed her forehooves on his chest and closed her eyes, as shivvers shook her entire body. So long as she didn't go too deep and bonk her cervix, this was wonderful.
Vagina to brain! This is what we needed!
Anus to brain! We're starting to have second thoughts here!
Vagina here! Today is my day, get to the back of the line!
Back of--! Was that a joke?
Twilight opened her eyes, and clenched her vaginal muscles. He throbbed in return and another orgasm--a different one, compared to when he had used his mouth--built.
She lifted herself again, quickly this time, and dropped her hips hard.
He gasped, and smiled up at her. "That's nice."
His face dripped with her juices, the coat matted on his muzzle, his eyes blinking her juices out, mane disheveled. He looked like he had just emerged from a shower.
She leaned down and licked his chin, around his jaw, and then planted a deep kiss.
Her hips kept working up and down as she sucked her own juices off his face, savoring her own taste and the sweaty-musky-library-y taste of her first lover.
First lover, she thought. I'm going to do this again. Yay estrus!
The fire that had built over the last week in her lower abdomen, deep under the muscles, around her uterus and ovaries, now was spreading across her lower body, a different sort of fire engulfing her canal and making her clit and lips and asshole and tail all spasm in time. Her thrusting turned rhythmic, regular, and he added tiny little shifts upward of his hips in time, which gave her that tiny extra fraction of an inch that seemed to make all the difference. Now that she was in the zone, the tiny little nudges against her cervix were... nice... "oh Celesssstia...."
She sucked her own pheromones and pussy sploosh off his cheeks and her biggest, wettest, most brain-bending orgasm of all hit, her vision graying out and swirling with stars, a splash! sound echoing across the library as she soaked both their hips and tails and the floor below them, her channel tightening around him so hard that he gasped and shuddered and his eyes rolled up and he made a "sssssrrrnnnkkk" noise and then--oh! Oh!--magma, his massive wet magmatic fire suddenly inside her and squelching out of her as she kept pounding her hips up and down and up and down and their mixed juices making splort splort splort noises as she pistoned and she looked over her withers again at her own bottom and tail, and his thick white spew was going everywhere, good gracious that was a huge tremendous ejaculation, getting white spunk across her bottom and his balls and into both their tails and slicking her butthole and that actually felt kinda good, in a naughty way, getting her butthole coated with juicy spunk and generally making a wet sticky mess and "Oh sweet Celestia here I go again!" her entire body clenched as one last massive wave rushed across her, and this time a few sparks shot from her horn and it wasn't as gushy down below but it felt so good!
She lowered herself one final time, and sat straddled across his hips, forehooves on his chest, panting.
They looked into each others' eyes.
Her entire bottom and environs throbbed, their mixed wetnesses cooling in the library's air.
"That was just what I needed," Twilight said.
"Wow. Yeah. Me too!"
She leaned forward, lying down on him, and nestled her head against his right shoulder, chest-to-chest, belly-to-belly, his penis still deep inside her, but softening with each heartbeat.
"Now this is nice," Azure said, wrapping his forelegs around Twilight's withers.
"Mmmm-hmmm," she murmured into his neck. "Remember health class?"
"Oh... oh, gracious..." he gasped, and his entire body--well, less one part--stiffened. "Are you--"
She chuckled, and nipped his right ear, careful not to draw blood, this time. "You ask that now? While I feel that enormous load dripping out of me?"
"Well?!?" he choked out.
"I've got an implant. We're safe."
His body relaxed underneath her. "Wow. Lucky."
"Shhhhh," she said. "In health class, they said this part here, the cuddle, is what actually breaks your estrus. Just hold me for a few minutes, okay?"
"Really?"
"Well, yeah. How else could fillyfoolers break their heats?"
"...huh."
He hugged her, and she nuzzled deeper into his shoulder. He lost his erection and slipped out of her, with a wet slurp sound. A large wad of his seed dripped out of her, soaking her clit and his balls.
"Almonds?"
"Hmmm?"
"Could you please... rub my withers?"
"Of course."
She drowsed against him, enjoying the warmth of his body, the chill of their mixed drying fluids, and his hooves rubbing the now-sore muscles of her withers, and she fell not quite asleep, but not fully awake, either, as the sickening throb of estrus hormones finally quieted across her body.
"Twilight?"
"Hmmmm?"
"Feel like your heat is broken, yet?"
She sat up, and squirmed her hips against his abdomen. "Yeah. I think so! I'm not waiting a whole week next time. I'm grabbing the first one of you I see, the minute it hits. I'll get so much more studying done this way, if I just rut my heat away instead of having my brain buzz with hormones for a week."
Twilight giggled. "Why didn't anypony tell us how easy this was to fix?"
She climbed off him, and stood, shakily, on all fours, looking down at him. "Moon Dancer still needs her heat broken, she's complaining about not being able to study, either. Want me to recommend you to her?"
He hoofed at his bleeding ear, and then at his swelling testicle. "Yes! But first, can you help me limp to the nurse's office?"
Twilight paled, and gulped.
Celestia snuck away, quietly, and made her way to the infirmary, beating the two lovers there by about five minutes, and spent the wait chatting with Nurse Sternheart, an older unicorn mare.
Twilight barged through the infirmary's swinging door backwards, pushing it open with her bottom, and leaving a smear of vaginal fluids and semen on the varnished wood. She levitated Azure Almonds in and gently placed him on the nurse's triage table.
"Well, my most faithful student," Celestia said, "I see your levitation has improved markedly. Mr. Almonds weighs twice what you do, yet you handled him easily."
Twilight and Azure looked at the goddess-ruler of Equestria--even worse, headmare of their tremendously selective and prestigious school--and gasped.
A wad of semen fell from Twilight's vagina and landed on the tile floor with a loud splat.
The entire left side of Azure's face was bloody from his torn ear, and as the adrenaline of the sex wore off, he breathed through gritted teeth at the pain in his swelling testicle.
Nurse Sternheat looked at Twilight and asked, "Back so soon, Ms. Sparkle?"
Celestia cocked her head. "Back?"
Twilight blushed and flicked her tail. More semen landed on the tile floor.
Celestia walked to Twilight and laid a wing over her withers (which were about the only dry, non-sticky part of the student's body). She said, "Anything I learn in this room, Twilight, I will treat with medical confidentiality."
Looking at the floor, Twilight mumbled, "Nurse Sternheart had to remove a glass soda pop bottle from my... nethers... yesterday."
