The Only Thing Harder Than Pre-calc

It's the last day of senior year and Polly is struggling a bit during her last class before graduation. She thought the Tail Virus was done with her and she'd just have to rely on estrogen to give her the feminine body she wanted. That said, her chest and the space between her legs have been tingling all morning and she swears her tits are a little bigger.

There are a lot of rumors going around about Elara the bunny girl that sits in the row in front of Poly in pre-calc. One is that Elara is dualsex and has both sets of parts. Another is that Elara's horse hung and has the largest dick in the entire school. Both have made Polly's crush on Elara much worse.

When Elara sniffs the air and then passes Polly a note asking if she needs help, Polly's desperation to get fucked becomes overpowering.

By the end of class, the only thing harder than this pre-calc will be Elara's dick and the only thing either of them will be thinking about is how to fit it into Polly's new pussy.

The Only Thing Harder Than Pre-calc

By Zmeydros (Polly)
(Edited by Chaundra, Xaziana Tenebris, AkikoTigress, and WolfLeah)

The LED lights in the ceiling had curved, industrial-looking grates with thousands of tiny holes that obscured the center, brightest part of the oblong fixtures. Sitting at fourteen of the twenty little blonde wooden desks were students, six humans and eight mosaics (people who had been turned into animal hybrids by the tail virus). They scribbled down answers to a post-final pre-calc quiz with their number two pencils, sometimes looking up to read the whiteboards that covered the walls of the room. On the whiteboards, in just about every color of the rainbow except yellow, were helpful hints to the quiz questions written out in silly anecdotes and diagrams that Mrs. Thresher had made.

The directions for the quiz read: "Every problem you solve will give you points toward your final grade. All the answers are in this room. You can pass notes or text each other to help each other out, but no talking. Have fun!"

In the front corner of the room, near the blonde-colored wooden door with a tall, rectangular window in it was a fox girl mosaic, with deep reddish fur, her tail flicking as she worked. Behind her was a human guy who had his Padres baseball cap on backwards. To Polly's left was an edgy, cyan-haired girl with a bar piercing that went all the way across her left ear and a black upside down cross earring hanging from her right earlobe. In the front row, on the right side of Polly's crush, was a red-feathered gryphoness whose effort was also reflected by the flicking of hir tail. 

Sitting at the small steel teacher's desk that was off in the left corner of the front of the room was Mrs. Thresher, a curvy shark mosaic with lots of mom energy. Her long, thick tail swished as she read a Star Wars Old Republic novel and took sips from her lavender coffee mug. On her mug was "Triangles Rule" along with a bunch of trigonometry equations and diagrams. She was wearing a marine blue women's t-shirt that had "Hello there!" written bright yellow text.

Then there was Polly's crush, a bunny girl named Elara who was one row in front and one desk to the left. Her thick dragon tail had been intricately woven between the legs of her desk. The end of it was tapping on the back right leg of the desk while she thought. Her soft bunny fur, which covered the top side of her tail and the rest of her body, was white with black spots. It would've looked like Elara had been splattered by black ink if it wasn't for the black line of fur that went down her back and all the way down the top of her tail. 

Elara's wardrobe was something only a teacher's pet could get away with. She was wearing a purple sleeveless, mesh-backed blouse with low neckline that showed her D-cup cleavage and a green-and-purple plaid miniskirt. Her dragon tail was flipping up the back of her miniskirt enough that Polly could get a glimpse of her light pink panties, wide hips, and round, muscular ass.

Polly was two-thirds of the way through the quiz. Her gray head feathers and green cheek feathers flattened against her as she tried to concentrate. Her frilly, knee-length skirt, that was printed with a beautiful image of the keyhole nebula, was rippling like waves as she anxiously bounced her right foot. Her tits were aching, stretching the petite coral sports bra under her light yellow blouse. The touch of her light blue panties against the area just behind her balls felt far too good and the flesh there kept twitching.

Deeper in her abdomen, she knew something was going on. There was a tugging, like something pushing up into her, and it felt good, really good. She clicked her dark gray beak in annoyance as she tried to focus on a problem involving finding the volume of a swimming pool. The answer on the whiteboard made it pretty easy. She still wished she could get out of this quiz just go dive into a pool to cool the heat that was building in her.

Her eyes darted again to Elara's ass. This dualsex bunny had been the talk of the school ever since one of her dates revealed she had horse parts under her skirt, making her a laquine mosaic. The laquine strain of the Tail Virus was famous for turning people into mosaics that had legendary sex drives and oversized equipment. Polly didn't believe the rumor that Elara's horse parts were contagious, leaving her lovers with mare pussies and big equine dicks. That seemed like a tall tale, but based on how big the bulge between Elara's legs was, Polly did believe the rumor that Elara had the biggest dick in the entire school.

Polly had a feeling she was going to need that dick by the end of the day. Unfortunately, even though Elara had noticed her a few times, she'd frozen up and said something dumb every single time. Elara didn't even have to be there for Polly to freeze up, though. The Valentine's card Polly wrote last year was still sitting in Polly's locker because she hadn't had the courage to deliver it.

She sighed and brought her attention back to the pool problem. Her body left her alone while she finished it and then she moved onto a problem involving a roller coaster. She got about halfway through it before her tits swelled larger, causing her nipples to ache. Comforting herself by rubbing her beak against itself, she went back to the problem. Just as she was finishing it, there was a powerful twitch behind her balls and she had to stifle a moan. It felt like something was pressing into her from the outside.

A sudden, pleasurable rippling got her squirming and breathing heavily so she wouldn't moan. She couldn't stop her red tailfeathers from fanning or the tip of her small, tapered prick from poking free of her sheath, however. Elara's long bunny ears started to turn back toward Polly before her head followed. When she saw Polly's orgasmic expression, she turned away immediately. This reaction was similar to the rest of the class, except Mrs. Thresher, who was engrossed in her Star Wars novel.

Polly gripped her pencil a bit too hard as she finished writing out the answer to the roller coaster question. Her pussy was throbbing, the labia expanding until they were pressing against her seat through her panties. That throbbing got worse as her clit formed at the front. It ached as it formed, so many nerves suddenly coming to life. Then pleasure flooded from it, making her whole front flush and tingle. Her simple, tapered cock shoved itself further out of her sheath, pushing at her panties and the underside of her skirt. A high-pitched moan tried to make it out of her beak, but she clamped down on it. The squeak that came out was very soft, but it got Elara's ears turning toward her again.

Elara sniffed the air and then pulled a notebook out of her denim backpack. She tore off a small piece of paper and, as she wrote on it, she shifted in her seat. Then she passed it back to Polly.

Polly's eyes went wide as she was handed a note from Elara. Her eyes got wider when she read it. "Hey Polly, it smells like you're in heat. Do you need help?"

Every feather on Polly's body floofed while she blushed so deeply it felt like she was sitting in front of a bonfire. She flipped the piece of paper over and then froze, her feathers flattening against her. She didn't know what kind of help Elara was offering and didn't want to kid herself. Eventually, she just wrote "Yes, but I need to finish my quiz first." Her panties started getting wet as she handed Elara the note, her tail feathers flicking wider three times as she tried to control them. She knew there was no way Elara meant that she was going to help directly with Polly's problem.

Elara wrote another note and handed it to Polly. This one read, "I just finished mine. I'll wait in the empty classroom across the hall. Also, just in case we get separated," her phone number followed.

Polly looked into Elara's violet eyes as she gave Elara a thumb's up. The moment Elara turned away, Polly did a fist pump, palpable excitement rushing through her. She had Elara's phone number!? She had Elara's PHONE NUMBER! The feathers on top of her head stood up as she did an excited head bob.

Elara got up from her desk and gasped in discomfort. Then she unceremoniously popped her massive cock free of her panties. She grunted as it thundered to its full sixteen inches in length, reaching out further than the edge of her skirt. With her skirt lifted out of the way, her more-than-fist-sized balls were visible, stretching her pink panties.

"Whoops!" Elara said softly before pushing her cock downwards with one paw-padded hand and grabbed her quiz with the other. Since her dick was longer than her skirt, half of it was still visible, throbbing between her legs.

Polly stared at Elara's shaft. It was black, equine, and thicker than a soda can! 

Mrs. Thresher looked up from her book, her eyes quickly widening, as Elara hobbled up to her desk. Elara put her quiz in the plastic box on the corner of Mrs. Thresher's desk. 

As Elara walked back, Polly had to stifle a moan. She couldn't look away from Elara's prick. 

Leaning over her desk, Elara wrote a quick note and passed it to Polly.

Polly nearly happy screamed as she read the note. "I like you, so please don't leave me hanging. Let's help each other out so we're not all pokey while we're trying to get home." 

Polly nodded as her heart raced. Did Elara actually want to stuff Polly's pussy with her giant...? Polly shivered with arousal and started leaking precum from her cock tip as her brand new snatch started making a puddle of girl juice. She concentrated on keeping her feathers against herself so she didn't suddenly turn into a bird orb in the middle of class.

At first, Elara tried to gather her stuff while holding her cock in that less obvious, downward-pointing position. But she eventually got frustrated and just let her prick spring upwards, extending past the edge of her skirt. All eyes in the classroom were on her giant boner as everyone watched in stunned silence.

As the urge to leap out of her desk and lick up the pre beading at the end of Elara's dick got so big she put her pencil down, Polly made herself focus on the quiz.

The last question of the quiz was, "What line is Obi Wan Kenobi most known for?"

Polly didn't have to look at Mrs. Thresher's shirt to know that the answer was, "Hello there!" As she tried to write the answer, however, her pussy clenched so hard that she nearly dropped her pencil. Her panties were getting soaked, it felt so slippery between her labia, and there was this emptiness, like she would die if her pussy didn't get a dick inside it ASAP.

Elara got her backpack on and stumbled out of the classroom, one hand holding down her precum-dripping monster.

Taking deep breaths and bringing her eyes back to the quiz, Polly wrote down each letter of the answer. The moment she was done, she put stuff away in her red backpack. Then, she held her backpack in front of the tent in her skirt while walking up to put her quiz on Mrs. Thresher's desk. Mrs. Thresher turned to the next page in her novel and then gave Polly a big toothy smile before going back to reading.

As Polly exited the classroom, and crossed the hall, her heart pounded in her ears while her fem juices wet her thighs. It was so strange to feel the slippery mound between her legs squish as she walked, but it was also pleasurable enough that she was moaning softly. The clenching of her snatch could be felt as strongly as her pounding heartbeat. She walked straight across the hall and opened the door, paying no mind to the light blue lockers that lined the hallway or the graduation decorations that had already gone up.

Elara was sitting on the teacher's desk, one hand pulling her prick toward her muzzle so she could lick at her flare while the other hand was hidden by her balls as she rubbed at her clit. Her sopping wet panties were hanging over the back of the office chair. A moaning whinny escaped her lips as she bucked.

Polly quickly closed the door behind her, her feathers fluffing some. "H-hi Elara."

"Hi! I, umm, I know cuddling and maybe getting coffee would be a better way to meet up for the first time, but I'm currently way too horny for that." Elara moved the hand that was rubbing at her pussy up to her muzzle and licked it with her long, forked dragon tongue. "It smelled like you were in a similar spot, so I'm hoping you don't mind."

"I don't mind. I--" Polly clicked her beak nervously. "I think I need something inside me." She couldn't meet Elara's eyes after that.

"It smelled like you needed someone inside you, so that's not a surprise. And don't be shy about it. Us mosaics have a lot of needs." Elara bit hir lip, pausing for a moment. "Only issue is that, despite having this huge cock, I'm kind of a bottom. It's hard for me to get into fucking someone if my pussy's winking and being all needy."

"Are you saying that you want me to go in you first?" Polly's eyes were wide and her dick was harder than ever. Before she had a pussy, she'd gotten off an embarrassing number of times thinking about fucking Elara.

"I know I'd be able to get you back if you did. Sound good?" Elara's ears were pointing straight up as her smile was uneven, looking a bit nervous.

Seeing Elara be this vulnerable was lowering Polly's anxiety a lot. They both had needs and they were being open about them. It was way better than other interactions she'd had around sex. 

"Yeah, I can try. I'm not exactly experienced." Polly looked at the floor, feeling out of her depth.

"I'm experienced, but I haven't exactly been treated the best, so I've got some nerves too." Elara sighed. "Also, the Tail Virus strain that gave me horse parts never actually went dormant, so you could end up with horse parts. If that's not okay, I get it."

"That would be an upgrade for me. I'm annoyed at how boring my cock is." Polly's head and cheek feathers floofed up.

"Honestly, it's really hard for me to fit in anyone who didn't train for it unless they have mare parts." Elara moaned as her snatch winked so loud that the wet squelch it made echoed throughout the room. "Ngh! So I hope you catch my equine strain, for your sake."

Polly's tailfeathers fanned, her thinking Elara was hotter than ever. "About that, I kinda didn't have a pussy until the end of pre-calc today." She tapped the ends of her pointer fingers together, feeling very self-conscious.

"No wonder you need me so bad. You'll get something in there before we leave this room, I promise. I'll stick my tail in you if my cock won't fit." Elara motioned for Polly to come closer and stood up. "Come here, I've never kissed a girl with a beak before and I'm curious."

Polly walked over. Her heart was beating fast, but it was no longer pounding. Being a good six inches shorter, Elara looked up at Polly, a shy smile on her muzzle. Then she spread her arms for a hug and Polly accepted the invitation, pulling Elara against her. She felt Elara's soft, pert tits against her abdomen while Elara's shoulders pressed against the underside of Polly's tits.  Elara's thick dick was rubbing against the red feathers on the inside of Polly's left thigh.

Polly leaned her beak down for a kiss. Kissing the curve on the front of Polly's beak, Elara stroked Polly's back. Opening her beak more, Polly's strong, blunt tongue probed at Elara's lips. Elara answered by slipping her draconic tongue into Polly's maw. Their tongues danced, Polly's much stronger but less dexterous. She was feeling warm tingles from making out with her crush.

When Elara grabbed Polly's ass, Polly started grinding her modest, tapered cock against Elara's belly. She was one strong bunny and Polly could definitely feel toned muscles, but they were under a soft layer of fur and a little bit of fat. The result was that it felt divine rubbing against her.

Breaking the kiss, Elara reached between them and freed Polly's shaft from her panties. Then she rubbed her paw-padded hands on it, making Polly groan and drip precum. Elara moaned, bending down to suck the precum off of Poly's tip. She bobbed her head, wrapping her incredible tongue around Polly's shaft. She let out a soft whinny as she started fingering herself in time with her oral. Anxiety spiked in Polly as she realized Elara might not know her dick was at full size already, less than six inches.

Before Polly could try to warn her, Elara pulled away and lay back on the teacher's desk. Then she lifted her hefty balls, showing off her extremely plump and wet mare parts. The clit was as big as a cherry, the labia surrounding it making a teardrop shape. The clit was hot pink, like Elara's inviting passage while the lips around it were black like Elara's dick. Elara's tail was dangling down, the black scales on its underside matching Elara's horseparts.

"I need you. In here. So bad!" Elara's cunt winked, pushing her clit outwards while the lips closed in. Fem nectar dribbled down the underside of her tail.

Polly pulled off her skirt and then her top before working her way out of her overstretched sports bra. For a moment, she just stared at her tits, which were covered in gray-green feathers. They had been B-cups before but now they looked close to C’s. Euphoria made her smile at the edges of her beak while her cheek feathers fluffed. 

As she walked up to Elara, she aimed her prick at Elara's glistening cunny. Then, knowing she wasn't that large, she just shoved in. It was so very satiny, wet, and warm inside Elara. There wasn't much resistance, but Elara clenched and moaned sharply before Polly could make it all the way in. The texture of Elara's inner muscles was exquisite and Polly moaned at the tightness they provided.

"Keep going! I'm a bit overexcited." Elara took a deep breath and relaxed.

"Does it feel good? I know I'm not that--" Polly's feathers flattened against her as she spoke.

"Are you kidding? It feels amazing!" Elara moved her hips slightly so they were lined up better. "Pummel me with that rock hard cock."

"Okay!" Polly grabbed Elara's legs for leverage and started thrusting harder, groaning at how good it felt to spread Elara's plush folds over and over.

At first, Polly couldn't keep a rhythm going because she was so distracted by the extra weight on her chest. Her boobs had never been this big and it was mighty distracting, in a good way. Then there was the glorious eyeful of Elara's breasts and balls bouncing from their vigorous sex. Polly eventually found a rhythm, but something weird was going on with the lengths of her thrusts. On top of that, it felt like things were tight even though Elara wasn't clenching and her snatch was very stretchy.

Her eyes widened and her head feathers fluffed as she looked at her dick. It was darkening and was wider... and longer?!

"E-Elaraaaah? My cock's growing!" Polly moaned out.

"Isn't it cool?" Elara put her hands on Polly's tits, fondling them.

"Yeah! I love it!" Polly pulled all seven inches of her shaft out, seeing that the tip was getting flatter and more equine. "Oh, it's going to be beautiful!" Polly bounced on her feet.

"Absolutely. Now, get it back in me!" Elara spread her pussy.

With an energetic squawk, Polly shoved back in. That tightness continued in her prick as it kept growing. There was pressure in her balls as they started slapping against Elara's ass harder and harder. The feathers on her sac and sheath were disappearing into her skin as soft, black horse hide formed. Her pussy pulsed as her labia got thicker. Then her clit plumped up, rubbing between her labia as her balls tugged at the skin just in front of it. Her moans became higher pitched.

Elara put her hands back on Polly's tits as her tail moved up between Polly's legs. The underside was soon touching Polly's sensitive folds and Polly was gasping in delight. Her dick kept expanding as the faint outline of a medial ring could be seen about one third the way up the shaft. Polly's leg muscles were getting a workout, her shaft reaching ten inches long while being thicker than her wrist. She nearly came right there, seeing the rise of her flare deforming Elara's belly. Her balls swelled, nearly reaching the size of her fists. They felt so sexy, so satisfying as they clapped against the underside of Elara's tail and ass.

Polly's cunt was constantly leaking fem juice, quivering as it became more voluptuous. Feeling it ride against Elara's slicked-up scales was making her lose control of her hips as the urge to buck against Elara's tail fought with her will to keep thrusting. It was embarrassing how much her pussy was starting to mirror mare parts, how puffy and full it was. She could feel it was going to be every bit as amazing as Elara's snatch. With her pussy feeling so damn excited, Polly's hands were drawn to Elara's massive, sixteen inch length. She needed both of them to encircle its girth. As she stroked it, her snatch tingled, feeling even more needy.

Gaining another inch of length, Polly slammed into Elara, making both of them yelp in pleasure. Polly's medial ring got more and more defined, flicking Elara's clit and making her cry out in ecstasy.

"Ngh! I'm getting clo--OOOH--se!" Elara's pussy winked as she let out a soft whinny.

Elara's tail tip found its way into Polly's snatch over the next two thrusts and the moment it started entering. A static-like charge suddenly grew exponentially at the base of Polly's dick, in her balls, and in her depths as Elara stretched her open with her tail. It felt like someone finally scratching an itch she couldn't reach on her own along with the first sips of water after being stuck in the desert. And it was centered on her new clit, vaginal walls, and opening.

"Elara, I ca--AAAH--AAAAH--AN'T Stop it!" Polly's pussy pulsed along with her dick, powerfully as her tail feathers flicked. Her balls were hiking up against her groin while her red tail feathers fanned.

"YES! CUM IN ME--EEEHEHEEE!" Elara whinnied as her pussy contracted in powerful waves. 

Polly hilted herself in Elara. Her beak flew open, but instead of a squawk, she let loose a high-pitched neigh along with Elara. Polly's pussy undulated from her entrance to her womb. The sensation was like having waves cresting inside her as pleasure radiated from deep inside her abdomen. A much more blunt orgasm, like a whack from a two-by-four gushed from her dick like the thick spooge spilling out into Elara. Her flare swelled, trapping her jizz inside. With each spurt, her cock grew.

The tip of Elara's tail thrashed along with the rest of her body, making Polly's first vaginal orgasm reach new heights. Her whole body clenched as she squawked. As the intensity of her twin orgasms waned, Polly marveled at the bulge she was making in Elara's belly. Elara's dick, meanwhile, was spurting rope after rope of precum, wetting the fur on Elara's neck and chin. Polly pulled her dick up to catch the spurts, tasting the salty alfalfa and elderberry flavors of Elara's pre.

By the time it was all over, Elara looked pregnant and Polly's dick was fourteen inches long, two short of Elara's impressive sixteen. They both panted as they gently slid into afterglow. For a good while, they just stared at each other, but then Polly leaned down for a kiss. Polly squirmed a bit because her pussy was burning with desire as Elara's dick throbbed against her front. Then it winked hard around Elara's tail, making a squelching sound while pushing Polly's thick clit right into her sac. Polly gasped and shivered, feeling hot all over. Elara's tail had been nice, but it definitely wasn't enough.

Pulling her tail out of Polly, Elara smiled. "Does someone need my dick?"

"Gnnaah!" Poly squirmed as Elara's tail slid out. "Please, I think I'm going to lose my mind."

Elara spread her legs to make things less tight and Polly watched her cum-coated shaft exit, blushing under her feathers at the thick veins and how gorgeous her medial ring was. Having a horsecock was a great upgrade. As she got to the last third, which tapered ever so slightly, jizz started leaking out and dripping on the gray-and-brown tiles below. 

Polly's heart beat faster as she got closer and closer to popping her flare out. When it popped out, spooge flooded out of Elara, splattering Polly's balls and thighs as well as the side of the desk and the floor below. Elara pushed her tits up against the sides of her dick and moaned.

"Oh dear, we've made such a big mess." Polly's head feathers  fluffed as she covered her beak with her hands.

"Don't worry, I'm really used to myself, and girls who receive my horsey gifts, being this productive. I make frequent use of the mop closet and have never made the janitors clean up after me or my friends." Elara giggled. "Now get on your back so we can take care of your--"

Polly got on her back and spread her legs before Elara could even finish speaking.

"Good girl!" Elara lifted Polly's balls and put her small bunny muzzle right in front of Polly's mound.  "Oh wow, your mare pussy is so sexy."

"You really think so--OOOH?" Polly was interrupted by Elara's dexterous tongue licking into her hot, needy passage.

"Absolutely!" Elara licked across Polly's clit.

"EEEAAH!" Polly screeched as she got a jolt of pleasure. "Elara, please..." She shooed Elara's muzzle by gently pushing on Elara's forehead. Then Polly reached under her balls and spread herself open while her tail feathers fanned wide. "Fuck me!"

"Needy girl." Elara grabbed the end of her dick and lined it up with Polly's snatch. "Keep your breathing steady and every time you feel tension, take a moment to relax. I have a feeling you can take every inch, but let me know if I need to stop, okay?"

"Yes. Yes. YES. YES!" Polly chanted, her desire to be stuffed so strong her head was spinning.

Elara pressed her flare against Polly's entrance stretching her wider and wider. Eventually the tension gave, Elara's flare popping inside. Polly yelped as her clit sent a tremor of bliss through her. It was a little orgasm that made her head swim. Then her breath caught as she felt Elara's shaft press deeper. Her cheeks and chest flushed. She felt so vulnerable, so amazing, and she wanted to look at Elara, her crush's, face but she was too busy throwing her head back and moaning like a pornstar.

Every time Polly clenched, Elara stopped and waited for her to relax. Only a third of Elara's dick was in her and Polly absolutely wanted it all. She felt like she'd dove off a cliff wearing a wingsuit. Taking such a big dick, especially as her first, was giving her an intoxicating thrill along with the pleasure. Moving her hand to her belly, she felt Elara's progress from the outside. It was all so hot, her pussy started leaking like a poorly maintained sink, making Elara's entry even easier.

"You're doing great, hon! We're halfway there." Elara pulled almost all the way out and shoved back in.

"NGH! Feels so good!" Polly grabbed Elara's tits and started playing with them.

"AAAHN!" Elara arched her back as her nipples hardened.

Polly flicked Elara's nipples as best she could despite how clumsy she was from the immense pleasure. Elara growled and started thrusting faster and harder, adding inches until her medial ring made it in, hitting Polly's scandalously large clit.

"I'm CUH--UUMING!" Polly's pussy gushed, wetting her tailfeathers and Elara's groin as it felt like she was on top of a rocket.

Her whole body shook as ecstasy reverberated through her. Elara didn't hold back while Polly got off, instead, she kept adding more until her balls were pressed up against Polly's ass. Polly's orgasm kept going, her pussy convulsing around Elara's hard cock. Meanwhile, Polly's tits ached, gaining mass with every passing second.

As Polly fell into afterglow, Elara scooped her up and pulled Polly against her front. Polly instinctually wrapped her legs around Elara as Elara showed off her extremely powerful legs by walking them to the whiteboard and shoving Polly's back up against it.

"You know the best thing about bunnies?" Elara asked.

"Huh?" Polly  looked into Elara's violet eyes, the feathers on top of her head fluffing up with curiosity.

"They hop!" Elara started bouncing Polly on her lap while sandwiching her against the wall.

Polly's cock shoved itself out of her sheath, pushing up into the space between them. It was profoundly satisfying to be filled to the brim, to the limit of what she could take, by Elara's shaft. The pleasure was unbelieveable. She could feel Elara's flare moving inside her, the veins on Elara's dick rubbing against her inner walls, and Elara's more-than-soda-can-thick shaft stretching her repeatedly with its slight taper. But, best of all, was the way Elara's forming knot and medial ring were driving Polly's clit wild. It was like being hit by a machine gun full of pleasure rounds.

Tears started streaming down Polly's green-feathered cheeks. Ever since she started puberty, she'd felt like something was missing and now she finally had it. It had been like having an itch that no one could ever scratch. Now it was getting scratched by the girl she'd had her eyes on for years. And this girl, Elara, could really fuck.

"Are you okay?" Elara stopped, a worried grimace on her face. Her partially-engorged knot was just outside Polly's depths.

"I'm just so happy." Polly smiled with the edges of her beak.

"Gender euphoria is a hell of a drug." Elara leaned in for a kiss while slipping her knot inside.

Polly grabbed Elara's head, scratching behind Elara's ears as they kissed deeply. Their tongues danced across each other, Polly's boobs becoming fuller as her prick poked its way up between Elara's. If Polly hadn't been so focused on the kiss, she would've been embarrassed about how much she was grinding on Elara's knot.

When they broke the kiss, Polly let what she was thinking slip out. "You're so awesome."

"So. Are. You!" Elara bounced Polly on her thighs with each word.

"NGH! FUCK! AAAH!" Polly replied to each thrust, feeling the extra weight on her chest and loving it.

"You ready to get filled?" Elara thrust again.

"Haah! YES!" Polly bucked her hips.

"This feels so good, I'm gonna lose it. Hope you don't mind me getting a little rough." Elara growled with lust at the end.

"GO FOR IT!" Polly cheered.

"Remember, I warned you." Elara grabbed Polly's ass and held her up with remarkable strength.

Then Elara started making thrusts with a whole third of her shaft while keeping Polly planted against the wall. It required so much effort that Elara was panting like a steam engine. Her balls were smacking against Polly's ass. Every smack gave Polly extra pleasure, her instincts running wild by having such big, virile balls pounding against her. Polly's dick was fucking the space between Elara's tits, drooling pre while at full length. 

Soon Polly's tits were E cups and Elara's dick was harder than ever while precum was streaming out of it. Polly felt a familiar tingling, like tiny butterflies collecting on her clit, a special spot on the backside of her pussy, and at the base of her dick. She was careening toward the biggest orgasm ever. Having Elara so deep in her that she had a notable bulge in her belly was making everything insanely intense.

"I'm gonna make you so rrrrRRROUND!" Elara's flare engorged, dragging on Polly's passage as Elara went even harder. Their fucking was now making so much noise that Polly was worried the entire school could hear them.

"EEELAAAARRRAAAAA!" Suddenly Polly's entire body felt like it had been hit by a camera flash the size of Jupiter. Her tail feathers fanned while her head flew back. "AIIEEEEEE! SCREEE!"

The pleasure was unbearably fierce at first, but then it was like being next to a huge subwoofer at a dance club. Her body reverberated with pleasure as her mare cunt milked Elara's length and her dick spasmed, spurting her creamy goodness so hard that it went over their heads.

Elara roared like a dragon as she bit Polly's neck and jammed her knot in one last time. Her prick gushed like a geyser, Polly's belly swelling visibly from Elara's impressive productivity.

Polly felt like she was undergoing an exorcism. Her body flailed, moving without her having any clue what she was doing. Her dick was making a mess of their fur, splashing off the underside of Elara's neck. The sensation of her pussy being filled to the point she felt pregnant was making her see stars in her vision. Tears leaked from her eyes, her feeling like her body finally reflected the way she had always felt inside while feeling more pleasure than she thought she'd ever be capable of experiencing.

Planting her muzzle on the end of Polly's dick, Elara drank down the remaining spurts, her own dick not calming down until Polly was so full of cum that her belly was pushing them apart.

As they came down from their release, Polly was just staring across the room, feeling a palpable amount of awe and satisfaction. Every so often, she'd look into Elara's eyes, her beak hanging open. Eventually, when their eyes met and they weren't panting as hard, they kissed. Elara's tongue shared the delightful, tangy taste of Polly's cum. Polly's dick slowly made its way back into her sheath as Elara explored ways to kiss someone with a beak, even nuzzling Polly's beak to the side so she could kiss and nuzzle where Polly's beak met her face. During all of this, Polly floofed more and more until she was a content bird orb.

Elara sighed and held Polly against her, their cheeks pressed up against one another. "Where are you going to college?"

"I got into UCLA's gender studies program." Polly nuzzled against Elara's cheek, her feathers flattening against her. "I prepared myself for this being the first and only time we really get to see each other. I kinda blew all the chances I had by being too nervous to tell you how I feel." 

"Ehh, I was figuring out a lot about relationships and who to trust for my entire stint in high school. Turns out I have some really good news for you." Elara pulled her head away and looked into Polly's eyes. "I'm gonna be at Calarts, only a half hour to an hour away, depending on traffic." 

"Oh really!?" Polly's head feathers went up.

"Yeah, wanna see if we make a good couple?" Elara grinned.

Polly squawked excitedly when she tried to reply. Then she took a couple breaths to calm herself. "Yes, that sounds amazing!"
