Chapter Text

Sunday, Late Afternoon

To most students, returning to the hallowed halls of Luna Nova from the Forest of Beginnings was an occasion of great joy and celebration, and the end of a prolonged period of suffering.

For Akko and Diana, however, it was just the beginning of a long, long, long series of unpleasantness, starting with having to deal with Professor Ursula’s having seen the former’s head between the latter’s legs in a scene that was rather impossible to misconstrue as anything other than hot, passionate, dragon-on-rider action.

And though Ursula was able to keep up the polite smile and the feigned obliviousness, Diana and Akko were not nearly as skilled at poker faces. They spent a few moments in painful silence, feeling the mood get more and more awkward, before Diana broke the quiet.

“Professor Ursula, please know that if there is anything—anything at all—I can do to ensure your silence, just say the word and I will use every single connection, power, and privilege I have as a Cavendish to--”

Ursula held up her hand, and smiled. “Diana, Akko, it’s not necessary to bribe or convince me at all, your secret’s safe with me.”

The both of them heaved sighs of relief, before giving Ursula thankful looks. “Thank you, Professor,” Diana said, while Akko just beamed, tearing up at her idol’s giving her even more reason to love her.

Ursula smiled back, before her face turned serious. “If there’s one thing I will have to ask of you two, though, it’s to have a long, deep, and serious discussion about you your relationship upgrade. Believe me, rider-dragon Bonds get VERY complicated once you throw sex into the mix.”

Diana and Akko both nodded, their cheeks burning red. “We were already planning to, Professor Ursula,” Diana replied.

Ursula nodded. “Good. You two can use the ready room, if you’d rather not have this conversation back in your quarters, or elsewhere.”

“It will do just fine,” Diana said as she left, beckoning for Akko to follow.

They exited the warp stone chamber and into the ready room. Akko perched herself on one of the available seats, Diana double-checked that the door was locked behind, before she sat beside Akko on another chair. The two of them looked at each other, quietly collecting their thoughts, all manner of feelings flowing between them:

Nervousness. Embarrassment. Hesitation. Curiosity. Reassurance.

“So...” Akko started, “back there, when you tried to bribe Professor Ursula… does this mean you don’t want other people to know that we’re a thing now…?” she asked, trying to keep her voice calm.

Diana nodded. “Yes, but I assure you, Akko, that’s only because I’m not yet ready for the public to know about us—not before I’ve had time to think and prepare for how I’ll reveal our relationship. As you know, with my being a Cavendish, I’m held to a much higher standard than everyone else, and there’s so many conventions and expectations I need to uphold, I can’t just--”

Akko put a hand on her thigh, Diana stopped. “Can I please tell at least Sucy and Lotte?” Akko asked. “I promise I’ll keep them from spilling about it to anyone else, and I definitely won’t go shouting from the rooftops and the spires about how I’m your girlfriend now, even though I really want to.”

Diana looked at her, debated it for a while, before she slowly nodded. “Yes, you may, but just… do it in our room, with me around, please.”

“And have them sign something something so there’s a guarantee that they’ll catch hell if they do…?” Akko added.

“Yes,” Diana said. “Picked that up from our Bond?”

“Yep!”

Diana chuckled. “Hah, looks like it’s going to save us a lot of time and effort with communication...”

Akko nodded. “Mhmm! Still going to be a lot of things better said out loud like this, though: I love you, Diana,” she said, her eyes warm and loving.

Diana blushed. “I love you too, Akko,” she said, before she leaned in, closed her eyes, and kissed her.

Fwoosh!

Akko’s dragon fire surged into Diana, rapidly engulfing her entire being, the intense heat concentrated near her stomach. “Fuck me!” she cried as she pulled away, smoke and little tongues of flame pouring out from her lips.

“Oh shit—are you okay, Diana?” Akko asked.

Diana coughed and beat her chest, before she sucked in a deep breath, and exhaled a steady plume of smoke. “I’m fine, I’m fine...” she said, before she stopped, her eyes widening. “… Actually, no, I’m not fine, I’m suddenly feeling incredibly, painfully turned on all over again—help...” she whimpered as she squirmed in her seat.

“Wow, you’d think your body would have gotten used to my dragon fire by now with how many times we”--Akko made a seductive dragon sound--”back in the Forest,” she said as she slipped off her seat and knelt down between Diana’s legs.

“Well apparently it hasn’t, and still needs your assistance!” Diana cried as she struggled to pull down her pants, Akko taking over and getting them down by her ankles. Her panties were already wet and stained dark with fresh arousal, and Akko couldn’t help but stop and put her nose on it, inhale the scent of her excitement and the remnants of their most recent trysts.

“Akko...” Diana whimpered, looking down at her pathetically, desperate need pouring in her side of the Bond.

“I’m on it, I’m on it!” Akko said as she pulled away, hooked her claws into the band of Diana’s panties, and carefully tugged them down between her thighs. “I’ve got you, Diana, don’t worry,” she said as she put her claw on top of Diana’s pussy. “Ready?”

Diana quickly put her own hand atop Akko’s claw, her fingertips starting to glow as she harnessed her magic. “Ready.”

Their Bond tattoos pulsed and thrummed, the ruby red swirls on Diana flowing like water, the icy blue streaks on Akko thrumming and humming like a fire. Diana whimpered and moaned as she felt hot, slippery fluid form over her pussy and Akko’s claw, till they were both soaked and drooling with it.

Enchanted lube was a temporary solution at best, dissipating very quickly without a sustained effort to replenish it; but with Diana leaking ever more arousal as Akko rubbed her nails up and down her pussy, and her serpentine tongue licking and toying at her clit, they needn’t have worried about that.

Ooh...” Diana moaned as she leaned back into the chair and grabbed the back of Akko’s head. “Y-Yes, Akko, please, keep going...”

Akko hummed in reply, her pointed ears twitching as she buried her face back between Diana’s legs, pressed her lips and tongue against Diana’s pussy lips. Diana moaned and gasped, whispering increasingly heated and breathless words to Akko, literal steam escaping from her lips.

Technically, their Bond was more than enough for Akko to get an accurate read of whatever Diana was feeling at any moment… but really, there was just something about hearing Diana say it out loud, the worsening warbles and tremours in her voice, the moans and the whimpers in between her words, some of them cut short by a gasp or a moan.

A hot puddle of her Diana’s arousal began to on the seat of her chair, trickling across the worn-smooth wood and to the tiles below them. Her panties started to stretch, the metal buckles and zippers of her pants clinked and jingled as she spread her legs wider. The dragon fire inside of her started to burn hotter and hotter, making every last sensation all the more intense, the pleasure consuming and overwhelming her thoughts till it was all she could think about, all she wanted, all she needed...

… Then, suddenly, Akko stopped, the flames suddenly turning into a painful, hungry gnawing now that they she wasn’t feeding and stoking them.

“Akko...?” Diana whispered, tendrils of smoke pouring out of her mouth, her eyes wide open and wild.

Akko pulled her face from between Diana’s legs, her lips and scaley cheeks shiny and dripping with her arousal. “I want to put your chair against the wall, so I can climb on, claw-fuck you and kiss you without either of us falling off. Can I?”

Diana trembled, the heat inside her exploding like you’d just dumped a barrel of gasoline on it. “Get rid of your clothes and do it—now.”

Akko’s clothes burned into cinders, revealing her bare skin, her bright red scales, and the patterns of her Bond tattoos few ever saw. She effortlessly picked Diana and her chair up, carefully walking forward and putting them right up against the wall.

She checked to see if it would move, and when it didn’t budge, Akko climbed on, kneeling in the space between Diana’s legs, one claw on the wall for balance, the other already back on her pussy.

Diana looked down and watched, crying out and panting as Akko slipped her arousal-soaked nails into her, effortlessly pumping them in and out. Lewd, wet noises filled the air, the drip-drip of Diana’s arousal spilling onto the tile growing more and more frequent, and Akko’s own starting to join the mess.

“Diana?”

Diana looked up, saw Akko’s eyes, crackling and burning with lust and dragon fire. They started to close as she leaned in for a kiss, and shot wide open after Diana grabbed the sides of her head, lunged forward, and closed the distance.

Lips locked, tongues slipped into mouths and tangled with each other, muffled moans of pleasure rumbled in throats. Akko kept on pumping her nails in and out of Diana’s sopping wet pussy, arousal pouring and spilling out onto the seat and the floor, splattering onto Diana’s inner thighs, dripping from Akko’s claws. They pulled away for breath, Diana grabbed onto Akko’s shoulders, tilted her head back and cried out, feeling the fire inside her grow into a massive inferno, every last fiber of her being alight, before finally...

Akko…!”

The dragon fire inside Diana exploded, a flash of white coming over her vision, before her whole body shook and writhed from the shockwave, her pussy spasming and gushing like crazy onto Akko’s nails and claw, very literal smoke pouring out her mouth, her fingernails digging and scratching at her scaly shoulders, before they fell away, limp.

Diana alternated between coughing up smoke and sucking in air she sank into her chair, sweat pouring down every inch of her skin, her body still shaking from her orgasm. Akko pulled her claws out from between her legs and hugged her, pressing her naked chest up against Diana’s soaked shirt, affectionately nuzzling her cheek, their Bond tattoos glowing as Akko absorbed the excess heat from her.

Soon, Diana’s breathing calmed, her heart began to beat at a normal pace, and the overwhelming heat disappeared, replaced by a pleasant warmth washing all over her body as she melted into a puddle of sweating, smoking, satisfied goo.

Akko hummed as she pulled away, giving Diana an affectionate lick on the cheek. “I love you, Diana,” she murmured.

“I love you too, Akko,” Diana whispered breathlessly, her lips curling into a smile as tendrils of smoke lazily poured out of it.

They relaxed for a few moments more, before Akko climbed off, helped Diana onto a different, drier chair, and started looking for something to clean themselves up. She was in the middle of grabbing one of the towels when they both heard a knocking on the door.

“Girls?” Ursula asked. “Uh, I’d just like you both to know that the walls here aren’t soundproof, there’s a company of Freelancers coming here soon, and there’s deodorizing sprays under the sink.”

Akko and Diana’s eyes widened, their faces burning red all over again.

In record time, the ready room was cleaned up and the evidence of their tryst literally or figuratively burned, Diana was dressed and groomed, Akko was saddled and loaded up with all their bags. They were soon out the dragon-sized door and back to the campus proper, Akko rushing through the crowds as quickly and steadily as possible, Diana riding on her saddle and resisting the urge to wince with each step, the two of them keenly avoiding eye contact with anyone they passed by, human, dragon, or Fae folk.

Thankfully, it was standard practice to assume that anyone coming back from the Forest just wanted to get back to their dorm, a Bonded pair or a company of Freelancers.


CRASH!

Akko plowed through the balcony side doors of their room, the sturdy wooden bars breaking in a shower of splinters, Akko herself skidding and spinning across the marble floor until she crashed into the giant air bags on the far-wall.

THOOMPH!

Diana wheezed, her knuckles turning white as she tightened her grip on the reins of her saddle, and Akko climbed out of the cushions. She undid the straps of their bags, letting them fall to the floor with heavy thuds, the clatter of some of their equipment and clothes spilling out.

On any other day, Diana would have demanded she put them all away properly, but all she could think about now was getting into the miniature hot spring that was their “bathroom.”

Akko made a beeline for it, Diana wincing and whimpering as she bounced about on the saddle. Akko slowed to a stop at the shallow end, carefully picked Diana up, and lowered her down into the water. Diana yelped and tensed up as she sank past her waist, before she sighed happily and relaxed.

Akko transformed into her humanoid form, naked but for her saddle, now in the shape of a leather body harness. “Is there anything I can do to help, Diana?” she asked as she leaned on the edge of the pool.

“Can you please get me out of my clothes again, and get my comm-crystal out, too...?” Diana asked.

Akko nodded. Soon, Diana’s clothes and Akko’s saddle were hung up to dry on the side, and the both of them were in the water, Diana resting her head on Akko’s shoulder, their comm-crystals resting nearby on the rim.

“Better now…?” Akko asked after a few minutes of pleasant silence.

Much better...” Diana said. “Though I’m rather certain I shouldn’t do anything but lie down and read for the rest of the day...”

“We really need a plan for when we”--Akko made a seductive dragon sound. “We definitely can’t just keep doing like we did back in the Forest.”

“Agreed...” Diana replied, frowning. “I’m going to start remaking both of our schedules: we’re going to need a lot more ‘bonding time’ from here on out.”

Akko chuckled. “Geez, Diana, planning to make up for lost time?”

Diana blushed. “W-Well, yes, I am! But more importantly, this a manner of practicality; I’ve studied most every book and material about the Dragon-Rider Bond, and I know that pairs that get intimate for the first time tend to get rather… enthusiastic about it in the beginning, due to the novelty of it all.

“Regardless of how active our respective libidos are from here on out, I’d rather we have to fill in free time, than struggle to find more of it in the heat of the moment.”

Akko snorted, steam trickling from her nostrils.

Diana blushed harder. “Pun not intended...”

Akko’s face softened. “Do you want me to go get some supplies from the dispensary?”

Diana nodded. “Please do, though be discrete about it: just the absolute essentials, a day or two’s worth for the moment. I don’t want anyone connecting the dots this soon...”

“I will,” Akko said. “I could go right now, if you’d like; they stock stuff for aftercare, too, and I’m sure they’ll have something for you.”

Diana hummed. “That would be excellent, thank you.”

Akko kissed Diana on the cheek. A burning mark in the shape of her lips glowed on the skin for a moment, before it faded away. “I love you, Diana, see you soon,” Akko said as she got out of the water.

“I love you too, Akko, and please, take your time if it means throwing off suspicion,” Diana replied as she grabbed her comm-crystal from the side.

Diana spent the next fifteen minutes remaking their schedules, and sending out all manner of messages to the various establishments and organizations of Luna Nova. It pained her to see all the replies begging her to reconsider cutting them off from her time and expertise, but thankfully, no one argued when she said she needed time to herself and Akko.

Figuring out how they were going to be doing things now that they were getting intimate counted as “newly arisen, unexpected issues” with their Bond, right?

She spent the rest of the hour taking a proper bath with soap, water, and no hot rider-on-dragon action, dressing in her most comfortable nightgown, then laying on her bed, reviewing the lessons and upcoming quizzes and exams now that they were back in Luna Nova.

It was shaping up to be a peaceful, quiet night settling back into school life, until Akko came rocketing back in dragon form, several massive crates strapped to her sides and back.

THOOMPH!

Diana’s eyes widened as she looked past her tablet and at Akko struggling to pull herself out of the deep crater in the air bags. She quickly put it down, got off her bed, and stormed off to Akko, wincing and slowing down as her pussy began to ache once more.

“Ilaya’s Grace, Akko, what did you not understand about ‘the absolute essentials?!’” she cried as she got near.

“That’s what I told them!” Akko said as stepped past their saddlebags from earlier. “But they wouldn’t let me leave unless I brought ALL of this back!” she replied,

Diana grimaced; with Akko’s well-known clumsiness, ineptitude, and penchant for causing all manner of collateral damage, she probably shouldn’t have been so surprised the dispensary staff would cover every singe base they could think of.

If it was any comfort, the crates looked just like any other, meaning passersby couldn’t have even begun to guess about the contents, or assumed it was any number of innocent, inconspicuous supplies. For all they knew, it could have just been an extra large shipment of the things they needed regularly.

However, there was still another concern: “What in Isigrol did they give you?” Diana asked.

Akko pulled out a messenger tube from one of the crates; Diana opened it, and found a shipping manifest. Aside from the delivery of their usual enchanted fire extinguishers, useful potions and drugs for an avid magic-user like Diana, and nutritional supplements for Akko, there was an incredibly large number of items for sex, be they for protection like heat-resistant “claw covers,” for aftercare like “Rough Rider’s Remedy (TM) Topical Ointment: ‘Flaming Hot Special,’” or even for helping aiding the act itself, like “Rough Rider’s Remedy (TM) ’Supernova’ Sexual Lubricant.”

Diana was well aware that Luna Nova was avid to keep its reputation as being very well-stocked, in spite of the declining enrollment rates realm-wide, but it wasn’t until that moment that she truly realized just how well.

“Do they expect us to use all of this…?” she whispered, embarrassed beyond relief.

“Probably not!” Akko said. “I guess they just assumed I’d be getting steamy pretty often. That, or I’d end up with a LOT of people and folks who really can’t handle dragon fire.”

Diana nodded. Out of morbid curiosity, she opened one of the crates; inside were incredibly large sealed packages, all of them labeled “Flying Dragon’s Large.” She sighed as she turned to Akko. “Couldn’t you have at least mentioned that you’re getting intimate with a human? There’s no way we can use these things!” she said as she gestured to them.

Akko couldn’t blush in dragon form, but the look that came over her face was evidence enough, the embarrassed feelings pouring in from their Bond only confirming it. “Uh, actually… we kinda can...” she muttered.

Diana raised eyebrows at her, before she looked back at the box. She hadn’t noticed it earlier, but there was a small, definitely human-sized box attached to one of the corners. She opened it, found several vials; she picked one of them off its holster, and read the label:

“Fuck Physics (TM) Alchemical Sex Aid: ‘You bet your ass it’s going to fit!’”

Diana’s face turned red. She slowly, carefully put it back in place, closed the box, pulled the lid back on the crate, and made sure every single locking mechanism on it was securely in place. “… I’m going to go to bed now, Akko… don’t bother cleaning up, we can sort this all out Tuesday after class, among other things...” she muttered as she began to leave for her side of the room.

“Wait, Diana!” Akko cried, before she started opening crates, found and pulled out a box of something. “Take this—the menders said it’ll help with your uh, problem,” she said with the box between her teeth.

Diana took the partially soggy and bitten cardboard box, and read the label. “Rough Rider’s Remedy (TM) Vaginal Suppository: ‘Lady’s Lifesaver.’” Her face continued burning red. “… Thank you, Akko, that was very considerate of you...” she mumbled.

“You need some help getting it in?” Akko said. “I know I always do when it comes to backdoor deliveries.”

Diana shook her head as she carried the box off with her. “I’ll manage on my own, Akko; remember, us humans are a lot more flexible than you dragons.”

Akko giggled. “Don’t I know it...” she purred.

Diana scowled and kept blushing. “New rule: no sexual innuendo, or intentionally riling me up in public.”

“Got it!” Akko said, puffing up her chest as she rose in attention, before the two of them went their separate ways, Diana to her bed, and Akko to her nest in one corner. They settled back in and went to sleep soon, ready to go back to their normal lives in Luna Nova, save their new, secret for the moment romantic relationship.

… Or so they thought.
