Opening an Unlocked Door Ch. 03

Trunk was trying not to look too happy. His son had just gotten a life changing medical diagnosis, one that would leave him the slave of a hyperactive libido that demanded satisfaction multiple times a day. But now he could finally field an entire team of wolves during the football game at the family reunion. Plus it had always been... difficult trying to make sure that Logs felt supported and loved. Lupines really depended on scent and pheromone signaling. Facial expressions were... fine, but nothing beat a blast of affection and packship chemical signals the moment you saw your family in the morning. It kept you grounded and supported.

"Dad... It's fine, I know you're excited." Logs said, reading some medical printouts.

"Huh?" Trunk asked surprised. He tilted his head.

"Your tail has been wagging a mile a minute ever since the doctor said what was going on." Logs flipped the page, revealing a packet on Hypersexuality Under Nonadolescent Gains.

"Ah... right." Trunk let his tail start to wag again.

"I'm... feeling alright? Not really sure how to process this..."

"How's Gust handling it?"

"He's freaking out a bit. Feels... very responsible. He said he was going to go work out. Try to get in a better mental state."

"... yeah. That's fair." Trunk said. "Have you thought about whether you want to stay in school during all this?"

"Well, it goes faster if I stay around the trigger..." Logs said, trying to sound clinical, but his scent was tinged with arousal.

"Alright, your room will stay made and read if you want to come home at any point." Trunk said.

"Thanks dad. Umm... any advice?"

"You're going to want something icy to suck on. My teeth being replaced by fangs was probably the worst part. Maybe wear a kilt or skirt. Your junk is going to swell over the course of a day and underpants are going to be difficult to stay ahead of. I'll try to bring you some clothes but..."

"There's going to be a bit of a jump." Logs supplied.

"Yeah... human to lupine has a middle part where clothes aren't really going to work. Maybe some of your brothers' older sweats..."

"That'll be nice. At least until my fur grows in."

"It's going to be patchy for a while. And you're probably going to feel pretty hot. Temperature regulation takes a while to get back on track. Ice baths can help." Trunk said, and the silence between the two stretched out for a few seconds. "Alright. Well... You want to grab food on the way back? I'll bring you and your friend back to your dorm. Make sure you're comfortable."

"Thanks dad, I really appreciate it."

The doctor walked back in, juggling a number of prescription scripts, dietary guidance, descriptions of treatment, and the details for a few local support groups.

"Thanks doc, I'll read this stuff over. Any restrictions on sexual activity?"

The doctor chuckled a bit. "Make sure you're hydrated. If anything starts to hurt or become uncomfortable, feel free to call the office and we can help you figure out if it's something you need to come in for. Expect stuff to be very sore and to feel very tired, but there shouldn't be much pain, other than stretching depending on when everything grows. You have any questions?"

"Not really... I'll try to read through all this first... then do some research if anything jumps out at me."

"Sounds good. Do you need a wheelchair?" The doctor asked.

"Probably not?" Logs guessed.

"Alright, the exit is just down the hallway on the left." The doctor left the room, leaving behind the prescriptions.

"Hey, dad, you mind grabbing Gust and picking up all the supplements and prescriptions I'm supposed to grab?"

"Absolutely. You need some water?" Trunk offered.

Logs nodded, and Trunk passed him a water bottle before leaving the room. Logs took as sip as the door closed, then finally let his legs apart, stifling a moan as a meaty slap filled the air, droplets of pre flying through the air as his new shaft bounced off his upper stomach. He looked down at the angry purple spire that had been a constant distraction the entire day.

He'd... grown. Aggressively. His dick was entirely mutated, long, hefty, and constantly dripping. It was definitely an alpha's dick, with a furry sheath, fist sized knot, and a pointed head that dripped between his pecs, begging to be sucked and licked. Just a constant stream of demands, wanting to be stimulated as Logs walked between specialists. His macros were good, his bones were good, the only issue was that his hormones were clearly intended for someone literally twice as tall and four times as heavy as he currently was. Just a constant outpouring of... everything. He groaned as his groin clenched and cloudy liquid sprayed against his chest, his balls aching to be unloaded inside someone.

He reached down, hesitantly touching himself. He was... slick, his hands easily sliding across the sensitive skin, as his dick turned from red to purple, eagerly loving the attention. It pulsed, swelling, pressing against his chest, begging to be sucked. Logs leaned forward and the salty bitter scent filled his head as he breathed heavily, his mind going blank. He opened his mouth and gave his shaft a lick. He shivered at the sensation. He was like anyone else, stroking... fairly frequently, but this was... different. The same sensation, compressed down. Both hands joined in his tongue and his brain went blank. It stopped being a want and shifted into a need, as both hands, his chest, his mouth started stroking his massive shaft.

He slowly thrust, the slick flesh moving between his arms and chest, as his balls churned, swelling even larger, if that was possible. The strain... just felt better, as his balls pulled down, his sack straining, the sensations adding as the thrusting shifted into bucking in his hospital bed. His mind went blank, white, slowly pushing over the peak.

"You ready for class?" A familiar voice asked moments after he reached the peak and he knew he was going to unload.

Logs kept the peace of mind to keep sucking, his mouth on his shaft as the first pulse of bitter salty liquid. Then gagged after the second, third, fourth, and fifth blast overflowed his mouth and spilled out on his face, leaving him a cummy wreck in front of his boyfriend.

"... in a moment" Logs manged, trying not to groan.

"Mind if I help?" Gust asked, leaning in and kissing Logs on the mouth, slowly licking him clean, swallowing.

"No..." Logs murmured, hands playing over the built pecs of his griffin boyfriend. Gust smiled, his wings flaring, bumping the IV stand.

"You're adorable... how are you feeling?"

"... overwhelmed? Like... fuck, this thing is big and needy." Logs murmured back. "Makes me feel a bit dizzy."

"I... kinda like that. You're hot as fuck." Gust said, leaning in for a kiss.

A nurse walked in a moment later, checking up on an EKG reporting abnormal outcomes as the two were covered in white goo, making out, ignoring Logs's pulsing balls that would not stop.

***

A few hours later, the two were back in the apartment, trying to figure out what pants Logs could still use, their schedule for the day completely shot.

"... jeans no, kahkis no, guess it's some form of sweats?" Logs said, trying to work around the bulge between his legs.

"You could always go with a kilt. Your dad did recommend it." Gust said, wings continually beating in the still air, turned on as anything.

Logs groaned, but nodded. Trunk had dropped off some of his siblings old clothing, which was tent-like, but usable. He wrapped a tartan skirt around his waist, then used a belt to pull it tight, It... stayed in place, despite the unsheathed shaft swinging just below the edge, his heavy balls pushing it forward. "I... look like the world's biggest perv." He complained to Gust, blushing. Gust couldn't get over the difference, flat chest, bony arms, thin legs, massive throbbing dripping tent constantly half hard and demanding attention. Logs noticed the admiration, and blushed, a new feeling seeping through him. It was hard to frame as anything other than... delight. He could barely resist playing with his new length, even as it hardened threatening to lift the skirt... completely impossible to ignore. Logs knew that the the head reached almost mouth hight, begging to be licked and sucked, its virile scent overpowering everything else and leaving him a moaning wreck...

Gust chuckled, breaking the horny spell. "You're adorable, you know that?" He asked. Logs was going to respond, but the scent of his leaky dick knocked any response out of his brain, and the sensation of his boyfriend touching it... comparing it against his forearm... showing off how much of a virile beast he was, as his vision went slightly dim from bloodloss... then Gust opened his beak and his mouth slid down the entire shaft, staring up at Logs, eyes filled with adoration as his new knot slipped through Gust's beak. Logs tried to keep it back, to keep his endurance up, but the sensation, across the greater length, and especially from his new knot... yeah, no. Logs unloaded. Again. Again again, his refractory period was... shrinking. Fast. He felt like he could spend the entire day cumming, and Gust was just able to milk out another whenever he wanted.

His churning balls pulled up as he clutched the feathery head of his new boyfriend, stroking the sensitive spots as he spurted, feeling the happy chirping radiate down his dick and up his spine, yet another load leaving him gasping and seeing spots, ass and thigh hurting as they clenched, trying to eke a bit more sensation as he gradually came down.

"You're not the biggest perv. That's your lucky boyfriend. And I will make sure everyone knows." Gust said, kissing Logs, leaving a thread of cum dangling between the two of them. "Now... let's grab breakfast, and go for a workout. You have a lot to build up if you're going to match your dad."

Logs slumped back, and gave a shaky thumbs up. He was entirely... overwhelmed. Not quite able to wrap his brain around Gust wanting to deal with all this... but he was definitely willing to go with it. And his doctor recommended it. Even better. Food, work out, if he could manage it, some schoolwork. The big goal was to keep everything properly anchored, which meant straining his new muscles as they kept growing...

He winced, as his shoulder spasmed, pushing against his shirt, swelling like a decent pump... or what he imagined to be a decent pump. Cross country had not remotely informed him on these changes. He knew that a pump existed, but did it... like actually lift a shirt that had fitted yesterday? Did it make him horny and want to make that part workout right? Did it encourage his boyfriend to kiss him and completely blank out his brain from any clear train of thought?

Well... the last one was definitely happening, even if it wasn't common.

"Let's go make sure you're as amazing as I see you," Gust said, rubbing his cheek against Logs's neck and chin. "I can't wait to lose to you in a bodybuilding competition."

***

The workouts were... different. Unending was the best way to describe them. He just didn't feel tired, his body easily taking in nutrition and turning it into mass. He felt hungry, horny, energized, and eager, but not tired. Even as he pushed into the third hour and his boyfriend called it quits, pulling him away to get a proper meal. Logs couldn't really disagree, his eyelids were sticking open from the salt crystals. It felt a tad disconcerting, as they walked across the campus common, dripping clothes and burning joints a background sensation compared to the little blob in his brain screaming happily that he was HOLDING HANDS with HIS MASSIVE BOYFRIEND.

Ok... upgrading that. It was a bit more than just a tad disconcerting. Everything was so much more intense and needy and just great. He felt giggly all the time and he couldn't stop looking at his boyfriend's bulge, and...

"You doing ok?" Gust asked, a tad concerned at his newly vascular friend. The little guy had... gone unreasonably hard, able to lift... honestly a lot, guzzling protein, always ready for more. He'd blanched when his phone alarm had gone off, saying they'd been working out for hours longer than he'd realized. It had just been... so nice. Just going from exercise to exercise, keeping up, downgrading as needed, trying higher weights, exploring each other and their own limitations. But that wasn't healthy. It was borderline dangerous, but... Logs had never looked better, all his clothes straining across his body, flushed, eager, newly thick cock begging to be fondled, even through his pants and compressions shorts.

"I... yeah. Yeah... I'm very good." Logs said. "Ummm..." He blushed, obviously wanting something, but not willing to say anything, as they passed by oblivious groups of people. A few canines blinked and sniffed, confused by the potent pheromones drifting off the giggly tiny human.

They made it inside and Logs looked around. "Umm... can you... you know... show me how to take something? I've... never tried something as huge as you..." Gust found himself pinned against a wall, Logs's head snuggling between his pec valley, two hands really really wanting to worship but needing permission first.

"I'd love to." Gust murmured, and guided two hands towards his churning balls, his dick straining his compression shorts "You really don't understand how cute you are..." He drew Logs into a kiss, lifting him off the ground, grunting a bit as Logs hugged back, pulling against his fluffy chest, sweaty skin pressing against feathers.

He carried Logs upstairs into the shower, throwing their clothes to the side, revealing two naked, horny bodies. "So... how experienced are you?" Gust asked.

"You'd be my first..." Logs murmured shyly, comparing his forearm... then the rest of his arm against Gust's shaft, impressed, and somewhat worried, his horniness warring with his prudence. Prudence was rapidly getting defeated by holy fucking crap, look at that massive thing. Prudence shifted from a cautionary angel towards an eager slut telling him not to miss his chance.

"Alright... let's try to do this right. You deserve it." Gust murmured, chirping quietly, nuzzling his smaller mate. He started washing Logs, leaving the smaller male squirming happily with all the affectionate touching, dick dripping with expectation and desire.

***

"... ok, this is not going to work." Logs sighed as the two lay on top of Gust's bed. Or, more accurately, Logs comfortably sat on top of fire hydrant sized monster that Gust carried between his legs. It was virile, heavy, and smelt like a dominant apex predator, but it was thicker than Logs' bike seat. He was literally sitting on it, and all his weight was resting on his glutes.

Gust chirped, a tad annoyed, his lion's tail lashing. He couldn't exactly disagree, it wasn't like he'd had sex with anyone under seven feet tall, and at some point size differences went from hot to a serious limitation. Sure, there were pervs who managed to fit horsedicks inside of them, but that was very much at their own pace, after stretching out a bit, with floppy shafts. He looked down his body, at the angry purple beast that normally swung between his knees, veins ringing it and extending onto his abs, and Logs purched at the top, feet playing idily up and down. Yeah... that wasn't fitting inside without severe soft tissue damage.

"Yeah... you're right. You want to fuck me instead?" Gust offered.

"You sure?" Logs asked, looking down that the bodybuilder.

"Yeah, I haven't had a proper stretch in a while, and you're perfect for it right now." Gust said.

"Sure... umm... thanks. I... didn't think you'd be into bottoming. You seem like... such a dom." Logs said, trailing off a bit.

"Oh, normally I am, but I'm not going to turn down a hot piece of ass like you. And sometimes giving myself a pec job while getting fucked is just perfect." Gust said, then squawked, not expecting to have actually... you know... said that. Out loud. A nearly 10 foot tall, half tonne, griffin doesn't usually lift their tail for many people. Especially not for a mostly normal human with just an 18 inch shaft. But... fuck it, Logs was cute. And he did smell really nice. And that was a really good looking throbbing eager shaft. Especially when it bounced off his chest, splattering the two of them with pre. "Yeah... can you get down to the foot of the bed? I'll try to shift around to give you easier access... Bit hard with my glutes sometimes."

Logs nodded dumbly, getting off the borderline stool, a strand of pre connecting them for a few inches before breaking. He got off the low bed and watched Gust scootch down, pulling his shaft between his pecs, dousing his feathers in lube to avoid rug burn. He carefully bucked once, his shaft easily sliding along his abs and chest, then trying it again with his hands, arms compressing his thick chest into more of a tunnel, the tip slipping through his beak and into his throat with each careful thrust.

Gust lifted his legs up, one hand hauling his heavy, nearly head sized balls out of the way over a thigh, exposing...

"Oh hey, you don't have a cloaca." Logs said, surprised. Gust chirped, annoyed, as if that was the most surprising thing about a griffin wanting to get fucked by someone almost half his size. "And you have a... pussy?"

Gust nodded, irritation building. "We can talk anatomy later! Can you just shove your stupid wolf dick inside of it before I get annoyed and shove your stupid head inside?" He cringed at the line. "Sorry... just... I... don't usually-"

He squawked, when Logs pushed a fist inside, expertly playing with his G-Spot, as he felt an experienced tongue teasing his clit. "Fuck... I thought you said this was your first time..."

"First time taking it up the ass. I had some pretty kinky fuckbuddies in highschool. They really encouraged me to learn how to go at it with... well... everything." He said, his hand slowly shifting from gentle teasing towards slow thrusting, fist making sure to brush against the rough part of Gust's tunnel with each careful movement. Logs kept up the efforts, loving Gust's chirps and gasps, tongue making sure that his erect needy clit was getting all the attention it deserved. Gust groaned and his wings stiffened as his first orgasm hit, a spurt of cum splashing him in the face.

Logs chuckled, and he fed his pointed head between Gust's dripping lips, slowly pushing in, careful to thrust smoothly, going a bit deeper each time, one wet thumb playing with the finger sized nub, leaving Gust panting and moaning, barely able to get out a word. "Fuck... you're good." He managed after another orgasm finished, stars slowly fading from his eyes.

"Don't worry, I'll keep going even after I cum." Logs said.

Gust relaxed, and laughed. "Oh, I am not worried." He murmured, slowly easing into the easy thrusts, his own dick starting to slide in time with Logs's thrusts, as he started swallowing himself, loving his own flavor.

Logs carefully thrust, abs tense, breathing controlled, pushing off his orgasm as he tried to thrust in and out as far as he could, angling up against Gust's G-Spot with every push, kegals tense as his newly enlarged balls churned their approval.

It was sooner than Logs wanted, longer than Gust expected, but Logs groaned and hilted, pushing in completely as he gasped, unloading spurt after spurt, his ass and legs spasiming. Gust's legs wrapped around him, pulling him in close, pushing hard against his clit, another orgasm crashing as warm seed filled him. Logs groaned, his abs and kegals finally giving up, and he nearly whited out. The sensations spiraling up from his dick, from his prostate, from his balls slapping Gust's ass... were nearly too much. He went limp against Gust, head swimming in sweaty, horny, needy, and happy griffin pheromones.

"Fuck man... Can you give me some tips? You did... really well there..." Gust managed after Logs stirred.

"Heh... yeah.... If you want to do it again."

"Fuck yeah, I want to do it again. That... yeah... you pushed me through orgasm after orgasm. It wasn't like... how it feels to be pinned down and dommed, like with my centaur ex... but... fuck, you knew what you were doing and how to use... everything. And your dick wasn't half bad either."

"Ugh... sorry it was so short." Logs complained. "Normally I'd go most of a night..."

"Don't worry. I'm certainly not."

Logs laughed. "Yeah... give me a bit and I'll start playing with your clit and G-Spot again."

Gust tensed his kegals, wrapping around Logs's still hard shaft. "Oh don't worry, you're about to discover one of the best parts about being a hyper." He curled up, pushing his head between his legs until he could give Logs a kiss. "We're all multiorgasmic... and your refractory period is probably shorter than the time it takes for you to get soft..." He started trying to milk Logs, his trained internal muscles grasping the shaft like a glove, slowly stroking it.

Logs gasped and he reflexively started thrusting again, his dick's oversensitivity fading into pure pleasure again. "... I think I'm going to like learning with you." Logs said.

"I can't wait." Gust agreed, laying back and starting to thrust, his waterproofed mattress slowly compressing under the weight of their combined emissions, prearranged barrels of water and protein shake near the beds to help them keep going without passing out from dehydration. "Now... can you show me your clitplay again? I loved that."

***

The two of them eventually stopped, collapsing onto the bed in a cocoon of warm wet horniness, Gust purring loudly enough to vibrate the dishes in the kitchenette. They closed their eyes, and fell asleep in each other's arms, completely exhausted, sore, drained, and brains swimming in endorphins.

Logs woke up first, feeling refreshed, aware, and as he breathed in his boyfriend's scent again, the stirrings of his libido making themselves known, his dick starting to rise against the feathers, still slathered in Gust's fluids.

"You're an eager one, aren't you?" Logs laughed as it brushed against his chin, catching a few stray hairs that hadn't been slicked down by all the oral.

"I could have told you that." Gust murmured, head reaching down and rubbing against Logs. "How did you sleep?"

"Ugh... sore... but feeling good. Sucks that we have class soon." Logs groaned. "I want to go at that again."

Gust blinked, a bit confused, and looked over at a clock. "Logs... it's dinner time soon."

"Wha? But... I feel like I've slept all night... and we went for forever yesterday... Umm... today. I was sure it was like... 4 am..."

"Nah... look." Gust pointed to the window where the setting sun was slowly making its way towards the horizon.

"... huh. So... that nap was like... a few hours?"

"Yep. I usually only sleep like 2 hours a day. Maybe a bit more if I worked out a bit too much."

"Hyper things?"

"Yep, it fucks with your brain chemistry and causes insomnia for a lot of people. Sleep is a weird thing. Like... yeah... you're supposed to get 8 hours but most hypers report that they manage well on one or two and feel well rested. Doesn't hurt that your libido and endurance are amped up to the point that you'll probably make use of that time. Definitely a field of active research. I think there's a sleep study ongoing if you want to sign up for it. They'd probably appreciate being able to track the brain shifts." Gust said, slowly stroking himself and leaking over the two of them.

Logs thought about it for a moment, as his dick demanded that it be shoved somewhere warm and tight, and it was right there, and there was a massive dick dripping onto the two of them, and... His stomach interjected with a loud demanding grumble, saying that it hadn't been satisfied and he'd burnt a shit load of calories today.

"I... maybe. Let's go clean up and grab food?" Logs managed. His stomach interjected again, sending a stabbing pain as it noted how empty it was. "Umm... food and clean up?"

"We can't go outside like this. Trust me. One, it's gross. Two, it'll spark an orgy. You're a potent little fucker, and you'll get a lot of people eagerly begging to be filled." Gust murmured, sending happy tingles up and down Logs' spine.

"Ok, shower and food. If... you can..." Logs said, trying to get out of the hug. It was futile, and Gust laughed as he stood up, carrying his boyfriend to the shower, where he eagerly cleaned every inch of the adorable half-lupine.

"You're getting some decent whiskers and the beginnings of fur." Gust noted, leaving Logs to feel his... well, everywhere. Yeah, there was new hair, a weird mix of stiffer and softer, his undercoat and coat and he swore that his canine teeth were just a tad sharper. He knew he was more sensitive to scents, or Gust was just shoving everything in his face. But it was reaching down between his legs and playing a symphony of pure desire and pleasure he couldn't ignore. Just... absolute perfection.

Logs winced as Gust rubbed... honestly any of the major muscle groups. His entire body was complaining about overwork. And yet... the overworked tube between his... ok, that's definitely knees. And those balls are definitely bigger than his fists now. Those two parts of his body were definitely still eager to get to know more of that smell, regardless of the rest of the complaints.

His shaft slowly rose, getting a laugh from Gust, and a thorough cleaning, leaving his balls churning. It was hard to tell what was... new from being new, versus just repurposed hormonal drives, versus... well just being overwhelmed, but Logs couldn't stop feeling his new furrier chin and... maybe thicker lips... they just felt so... sensitive... and-

Logs's head went blank when Gust kissed him, and he melted into the larger man's embrace.

"You're really really cute, you know that?" Gust murmured. "And I'll make sure to properly help you work out all the kinks in your muscles after dinner. And after that..." He grinned. "Let's see if we can get some kinks into your muscles. It's what got me mine." He stood up and made a pose, muscles bulging through his feathers. It took a lot of effort to get vascular definition through down. Gust had managed it.

"I... really think I'd like that." Gust managed, and the two headed off to dinner.

It was a simple affair. Protein, carbs, fats, and fiber, in quantities that left Logs's stomach aching. But he was still hungry, his body demanding more fuel, leaving Gust to keep getting up and grabbing more for the two of them. Gust carefully tracked the quantities, using a scale to make sure that he was following his own nutrition plan. Logs ate as much as his mouth would let him, jealous of Gust's lack of gag reflex and how far his beak could unhinge.

Gust chuckled. "Don't worry, you'll get to see exactly how much my throat can take in a few weeks." He said, as two thumps from beneath the table could be easily heard.

Logs blushed. "It wasn't that... just... fuck... more food. Can't get enough. Mouth too small." He complained before tucking in again.

"I don't know about that. I haven't seen lips that kissable in a long time." Gust said, leaning down and giving him a playful nip on the shirt. Logs felt like he wanted to squawk, or gasp, or pin down Gust and ride him on the table or... His pants ripped, tearing, causing Gust's pupils to dilate as their pheromones stopped being trapped by overstrained polyester and elastic.

"We're going to have so much fun." Gust promised, wing protectively wrapping around Logs, as a few other people nearby started sniffing the air. Gust stopped teasing as much after that. He really wanted to get Logs back to the room. And he didn't want to share just yet. He was still in the "amazed" part of the relationship, rather than in the "show-off-y" portion, where he was comfortable enough in Logs as a person and lover to bring him to orgies, game nights, sports competitions... you know, places where other people would be exposed to his self evident incredibleness.

*Fuck... am I in love with this adorable munchkin?* Gust wondered, as his wing pulled the cute, distracted, horny, hungry human closer. He wasn't sure... but... fuck, everything about him was hitting hard.

Logs's head was filled by the scent of horny, protective, griffin but it had started taking on a new edge. One he could only describe as... comforting? Home-like? A place where he wanted to return to and snuggle every night? It was the same feeling he got whenever he was around the family... sort of how... his other siblings described being part of the pack. *Oh well... there were worse situations to be in...* He thought to himself as he rubbed his head against the massive pecs of his bodybuilder boyfriend with a libido a mile long and a dick not much smaller.
