“Unnghaaah…..wha…..?” Twilight Sparkle’s eyes started to flutter open, her lips making small noises of pain and confusion as she woke up from what felt like a long slumber. She saw the flickering lights of torches, and felt the chill of the stone floor on her naked purple skin… “Wh…WHAT?” Suddenly, she jerked upright, looking down at her own nude body, blushing intenestly and covering her chest with both hands, and sliding her legs together, before looking with panic around the room. The last she had remembered, she was simply reading one of her tomes in the library, and now she was alone and naked in a fairly spacious stone room, clearly one that had been built with purpose - strange, forigen markings were chiselled into the grey surface, and torches sat in sconces, their light dancing around the chamber which, as far as Twilight could see, had no exit or entrance. “Hnnng….ggghhh…?” But in fact, Twilight was not alone, and she turned with a start to see the shape of another also starting to stir, squinting her eyes to see familiar purple and green scales. “Sp–SPIKE??” Forgetting her nudity, Twilight jumped to her feet and rushed over to the dragon boy, kneeling down beside him and turning him over - and blushing when she realised he was naked too! Her eyes darted away from his (undeniably impressive) privates. As much as the two had been inseparable through their journeys, they had always avoided seeing each other’s bodies this way. Twilight apprehensively brought an arm back to her chest, covering as much of her ample bosom as she could, her other hand trying to gently shake Spike awake. “Spike, are you okay? How…what’s going on?” Spike’s own eyes fluttered open at the sound of Twilight's voice, and he looked up at her with a smile, before also coming to the same realisations Twilight had, his eyes wandering to the girl’s barely covered breasts…and wandering down to his own fully visible… “WAAAAHHHHH!” he yelled, averting his eyes with a blush and covering his manhood, sitting up in a panic. “Tw-Twilight, you’re…I’m…we’re naked!” He glanced around the enclosed chamber with confusion. “What the hell happened? I was just tidying up the study and then I woke up here! Did you mess up another teleportation experiment?” “Pff, certainly not!” Twilight said with an annoyed glare. “And that only happened one time! All I was doing was reading! I was halfway through that new book on treasure hunting and…hmm…” Twilight’s face softened and became thoughtful as she recalled what exactly she was reading. “I had just read a passage about temples…was…did the book bring us….ahhhh!” THHNNNNGGGG. Twilight’s sentence was cut off as a loud, deep noise rang through the chamber, the flames of the torches swaying and dust kicking loose from the ceiling. It was almost like the whole chamber had throbbed, the sound reverberating deep in the two companions’ chests. “Ugh…wh-what was that?” Spike said, bring a scaly claw to his head as the reverberation faded out, and finding his eyes suddenly drawn to Twilight’s nude body, wishing for a second she would just uncover so he could see her beautiful….before he came to his senses, shaking the thought from his mind. Where the hell did that come from? But Twilight didn’t have time to respond, as suddenly another noise filled the chamber, the harsh scraping of stone against stone, as part of the floor started to slide open just in front of them. Twilight tentatively got to her feet, still keeping her sensitive parts covered and slowly walking to the new hole - leaving her round butt and tail perfectly in view of Spike, who, again, had trouble looking away from it. Twilight’s butt is…wait, what am I thinking? There’s more important things to worry about right now! Spike got to his feet too, shuffling over with two hands covering his crotch, as he looked over the edge to see what Twilight was seeinging - a short drop down into a water filled tunnel. They both gave another quick glance around the room, but saw nothing but impenetrable thick stone. The only way out was down into the water… “W-well, I guess we have to swim our way out…” Twilight said, almost subconsciously starting to take deeper breaths. “Wh-what? No way! Can’t you just teleport us?” Twilight shook her head. “I can feel something in this temple already affecting my magic…and even if it weren’t, I’ve no idea where we are! I’d just as likely teleport us into a wall and…” Twilight shuddered, having seen the effects of misplaced teleportation on objects before, and quickly pushed the idea of such things happening to their bodies from her mind. “But I…we’ve got no idea how far it goes, Twilight!” The young dragon boy was a more than capable swimmer, but his race were not blessed with the largest of lungs. “Maybe we should just wait and…wh-wha?” THHNNNGGGG. The same deep bassy throb rang through the tunnel, Spike’s sentence being cut off…and again, suddenly, he couldn’t look away from Twilight’s nude form, eyes widening and face blushing. “W-well…we’ll never be able to swim if we’re covering ourselves like this…I…I m-mean…” Twilight turned with a raised eyebrow, getting ready to scold the young dragon before a loud gurgle and crash came from the tunnel below - and the water level started to slowly rise, quickly starting to leak water into their very chamber! “Oh crap…” Twilight said, feeling the cold water on her bare feet. “Well, we definitely can’t wait now. And…” she glanced at Spike with a nod. “You’re right…we can’t swim covered like this…” Almost as if she was getting it out of the way, she took a deep breath and forced her hands to her sides, blushing as her curvy naked form was exposed to the young dragon. “I mean…we have to get out of here…and it’s just us so…” Spike nodded, again, fighting this new and weird compulsion to eyeball every inch of her body, before tentatively moving his hands to reveal his shaft - rather impressive in size considering his age, though again, this was more a product of his dragon heritage. “I- I won’t look, Twi, I promise!” he said. Twilight was like a sister to him, and he had never once seen her as anything but that, but yet again…ignoble thoughts started to swirl in his head - but as the water level lapped against he knees, he again realised there were bigger things to worry about. “R-Right…we gotta swim…I just hope it’s not too long…” Spike said, his bare chest starting to rise and fall as he took long, deep breaths. “Don’t worry Spike, there’ll be an exit or at least an air pocket I’m sure - and I’ll be right with you to help if you struggle, okay?” Twilight started taking deep breaths too, a little more confident in her own swimming and breathholding capabilities than Spike, knowing she could fill her ample chest with quite a lot of air - if worst comes to worst, she could share some of it with Spike, even though the prospect of that felt a little weird… …though for Spike, the prospect sounded amazing, and he nodded his head quickly, wading over to the hole in the floor, happy that the water level had risen to a point where his slowly growing shaft was somewhat hidden. “O-okay then…I’ll…I’ll just follow you, alright? But don’t go too fast!” The water level lapped against his chest, just starting to reach the bottom of Twilight’s bust, as he kept taking deep breaths, waiting to follow Twilight’s lead. Twilight gave the young dragon a nod and reassuring smile. “Just stay close enough to grab me if you need help, okay Spike? Come on, let’s get going before this room floods!” She took one last deep breath, her bare chest rising and her boobs bouncing as she jumped into the flooded tunnel. Spike was frozen to the spot, eyes having been locked on Twilight’s boobs as she breathed, and taking a glance at her ample flank as she dived - for a few seconds, he simply obsessed on the image in his head, his shaft twitching and starting to grow. “Wh–what am I doing?!” Spike shook his head from side to side and took deep breaths again, the water level already reaching his neck from his horny delay, and took as deep a breath as he could before submerging himself in the water and following his pony friend… …and as soon as he submerged, his vision was filled with Twilight’s naked body, bare breasts and ass bouncing in the water, as she gave Spike another comforting smile before turning to swim down the flooded cavern. Spike gave the tiniest burbly moan, following closely behind, eyes locked between her legs as he tried to get every glimpse he could of Twilight’s nethers. He kept pace as best he could, though his younger, smaller body couldn’t quite cut through the water like Twilight - but he didn’t mind. With Twilight in front, he could stare at her all he wanted, and his eyes darted to catch a glimpse of any private part of Twilight he could - her breasts, her ass, her pussy…but still in the back of his mind, he felt guilty and dirty for even wanting to look. What’s going on with me? He thought, his breathhold and swim stroke on complete auto-pilot as he followed Twilight as best he could. I’ve always thought Twilight was pretty but…I’ve never looked at her like… THHNNNGGGG. …oh god I wanna touch her so bad I bet her skin is so soft… “Mmmphhgblblbl?” Spike gave a bubbly yelp as another throb of the temple practically forced the thought into his brain, and Twilight’s form suddenly stopped in front of him, turning back as the water vibrated around them, making sure Spike was okay. Spike hung in the water with a blush on his face and rosy cheeks, nodding to her with a nervous smile…his shaft clearly a little bigger than before. Twilight blushed herself and quickly turned away, continuing her swim down the tunnel. Was Spike…getting turned on? Suddenly her swim stroke changed, as she tried to keep her legs closed so that Spike’s wandering eyes didn’t see anything they shouldn’t - but it was hard to stop her boobs and ass wobbling as the tunnel continued to stretch on and on with no end in sight. Spike was feeling the slight ache in his lungs as the dive lengthed, but it took a back seat to the conflict in his brain - and to the feeling in his crotch. It was impossible to hide his arousal now, even though a good part of his brain was screaming at him to stop looking at his friend this way. “Mmmphhglblb….” He gave a bubbly grunt of annoyance as he noticed Twilight’s attempts to hide her private parts. Hey, let me see that beautiful… “MMMPHHGLBBB!” Spike’s grunt of annoyance quickly became pain as he suddenly became aware of the ache in his chest, and his scaly stomached sucked the tiniest bit inwards as he blubbed out a cloud of air. With all the excitement, he’d barely been focusing on keeping his air in or swimming with any kind of discipline. His cheeks bulged as he brought a claw to cover his mouth, trying to continue the swim with one hand and slowly starting to fall further behind Twilight. “Mmmpphh….MMPH!” Even with his new found pleasure of looking at the naked pony in front of him, his lowering air was now starting to bring him back to reality somewhat, and his eyes darted between Twilight’s quickly escaping nude body, to the walls and ceiling of the tunnel, looking around for any sign of escape or air pocket. Still, none appeared, and Twilight was still swimming on regardless, not aware of Spike starting to struggle behind her, still feeling a little embarrassed and ashamed at her young dragon friend being so…pleased to see her naked. This wasn’t like him at all. The other pony’s had joked a lot about it, since they spent so much time together, but she’d never once felt anything romantic or sexual for her dragon friend - he was a little too young, for starters! And, if Twilight was being completely honest, she still wasn’t sure if she in fact preferred the company of other mares instead of… “HNNNNGLBLLBLBLB!” Spike’s next gurgle of bubbles was loud enough to grab Twilight’s attention as she turned back, eyes widening as she saw the dragon a little ways back down the tunnel - she’d been so distracted by her own thoughts, she’d ended up swimming quite a ways away, and Spike was using both hands to clap his mouth shut between rapidly reddening and expanding cheeks, just kicking along to try and catch up. “Spglbigkblblbebl!” Twilight bubbled out his name as she turned and swam towards him, not caring about modesty any more… THHNNNGGGG. …and as the cavern throbbed again, the struggling Spike’s eyes widened as he saw Twilight swimming towards him, her curvy, naked body bouncing in the water, the sound of her screaming his name through the water sending a shiver down his spine. Tinges of pleasure seeped into his moans of exertion, his shaft growing further as he kicked his way towards the pony, practically crashing into her as Twilight opened her arms and held him close against his body. “Arglbe yblouglb oblkably?” she bubbled, her bare chest pressed against Spike’s. The naked hug, the bubbly speech, Twilight looking down at him so lovingly…Spike couldn’t resist anymore. He let his hands slip from his mouth and leaned in, locking his lips against Twilight. “Mmmphhglblb…” “MMMMMPHHPHGLLBLBLB?” Spike’s moan of pleasure was instantly joined with Twilight’s whine of confusion, and at first she was going to push the young dragon away - but then she realised that the young dragon clearly needed air, and was too panicked to ask for permission. She gave a few little fidgets of discomfort, before holding Spike closely and locking her lips tighter, blowing a small stream of air into his mouth that Spike greedily sucked down - though this was a bonus to what he actually wanted. He just wanted to kiss the beautiful mare, and his tongue started to slowly push its way into Twilight’s mouth. “Mmmphhpglblblb….” Twilight started to blush, both from losing the air she was donating to Spike…and the fact that Spike was starting to lean into this kiss like he was her lover. She shuddered a little, truly wanting to break free from the kiss, but if this was helping Spike calm himself a little, she was happy to do it for her friend. Though, the feel of his dick pressing into her stomach was showing that Spike was anything but calm. Twilight finally broke this kiss, starting to feel a little pressure in her own lungs, and gave Spike a weak, awkward smile. Spike smiled back, eyes almost drunk with lust, before he snapped out of his stupor again, blushing and awkwardly looking away. Twilight let the young dragon go, before turning and offering her back. “Grblablb oglbnlbl…” she bubbled, directing Spike to grip onto her shoulders - she didn’t want him to get left behind again. Spike nodded, gripping onto her shoulders as she kicked her way down the tunnel, her own eyes now scanning around for any drop of air. The slight ache she was dealing with was manageable, but she knew the stale air she gave Spike wouldn’t last too long, and she didn’t have enough to give him any more - plus, she kinda wanted to avoid the dragon’s wandering tongue, and was trying dearly to… “Mmmmmmmmmmmglblbl….” …ignore the moans and humps of Spike’s body gripping against her. His erect shaft was nestled comfortably between her ass cheeks, his body rubbing against her back, and the hands on his shoulders starting to curl around just a little more to clutch at the top of her breasts. Twilight gave a few small squirms, uncomfortable at what the dragon was doing, but trying to focus more on getting them both out alive. Spike, however, was in heaven. Twilight’s skin and fine fur was just as soft as it looked, and he was quickly wasting his replenished air as he failed to hide his pleasure and arousal. The voice in his head telling him to stop groping up his friend was getting quieter and quieter, and it wasn’t long before Spike was softly dry humping the swimming pony, rubbing and grinding his body all over Twilight’s back. “Mmmphglblb…..glgblbmmph….” He was losing air in clouds, and soon the dull ache was already starting to build again in his chest. Twilight gritted her teeth, squirming her ass away from the dragon’s shaft, and trying to focus on swimming through the tunnel. Spike was holding so tightly, he could feel the slight heaves of his chest on her back - they were running out of time, and now bubbles were starting to force their way out of her own lips, as her cheeks started to balloon and turn red. “Mmmphh….” “Mmmmphh….arglblblb!” Spike heard Twilight’s tiny moan of pain, and that just spurred him on more, his hands moving even further down Twilight’s bare chest. But finally, the ache in his chest flared enough for him to notice, and he gripped Twilight’s body harder, burying his face in her neck and blocking the air from leaking from him, cheeks puffing up - and his lips and tongue starting to kiss Twilight’s neck as they swam along. Twilight, again, tried to focus on getting them to air - though she had reached a point where she would definitely need to have a word with Spike about these inappropriate antics. Spike, however, could barely discern that he was even being inappropriate. His chest was on fire, the time bought by Twilight’s shared air already running out, but that was low in his mind compared to feeling the slight struggles of the pony as her own air ran low, feeling little twitches and shudders in her body as he clung tightly to her. His shaft again found itself nestled between Twilight’s round ass cheeks, his own heaves and convulsions making it prod and poke in places it shouldn’t. If Twilight had known any better, she would’ve thought Spike was doing it on purpose. “MMMMGPHBLBLBLB!” But as the young dragon’s stomach sucked in painfully once more, his body curling and his shaft pressing up even harder against Twilight’s asshole, she knew it was just his airless struggles…at least, she hoped so… Spike’s grip was getting tighter and tighter, and Twilight was leaking air freely as she frantically tried to keep swimming, her stomach twitching in and out. She gritted her teeth and tried to speed up, noticing that the clouds of bubbles shooting from the dragon were getting smaller and smaller. She glanced back quickly to look at his face, seeing blue starting to join the red in his cheeks, his head lazily rising up, a few last errant bubbles leaking from his lips - there was no way she could share more air, her own chest heaving hard now. But as she rounded another corner in the long cavern, her eyes widened as she saw the tiniest glimmer in the ceiling above - an air pocket, finally! “HNNGNBLBLLBL!” Spike’s clutch on Twilight finally released as they rounded the corner, his eyes snapping open as he clutched a hand to his throat and another to his convulsing stomach, just about managing to keep the water from his lungs - but he didn’t have much time. Twilight quickly turned, wrapping an arm around his waist and pulling him a long, Spike’s blue cheeked face pressing into Twilight’s bare breast. Unconsciously, he started kissing and licking it, the taste of Twilight’s flesh mixing with the water of the cavern, as Twilight frantically kicked them forwards, air leaking quickly out of her pursed lips. “MMMMMPHHHGLBLBLB!” She grunted with the exertion, stomach sucking in to show the slight outline of her ribs, coughing out a cloud of bubbles with each stroke. Just as the waters started to leak between her lips, the pocket was right above them, and with a strong kick from the floor, she broke the surface with a deep gasp, pulling Spike up too. “GAAHHHHHHHH! Hhhhhhhhhh….” “Glblbhkk….kkhaaah….haaah….” Twilight took a greedy gasp of the air, as Spike coughed up a little water and took a few ragged breaths, tightly hugging onto Twilight, his head deep in her chest, and his still hard shaft poking up against the pony’s nethers. She held the dragon close as they recovered, but tried to squirm her hips away from his. “Spike…haah…are you alright?” Spike coughed out a little more water, before looking up at Twilight with what almost looked like a smile, a red blush still covering his face. “Yeah…haaah….thanks for the…haah…help….” He let his head drop, resting it on her bare chest again as he reached his claw to rest softly on one of Twilight’s breasts, almost as if he was going to take a peaceful map. “Wh-what…what are you doing!” Twilight didn’t want to let the dragon go while he was recovering, but his hands had explored way beyond Twilight’s comfort, as she blushed and squirmed. “I… I wanna help when you need it Spike but you were…kinda…” It was hard for the pony to even say, so bizarre was the situation, so she glanced down below the surface, gesturing her head to Spike’s still hard shaft. “Can…can you keep that to yourself…please…” Spike looked up at Twilight again with another strange smile. “I’m sorry Twilight…I thought I could swim faster but…I got scared and…I just felt calmer holding on to you…” Even while he spoke, Twilight saw his hand slide under the surface to grip his own erection, starting to slowly jerk it. “And…I can’t help this, Twi…you’re so pretty…” “Spike, what are you…” THHNNNGGGG. Twilight was interrupted by another harsh vibration in the chamber, Spike giving a low moan just as it happened, but she had no time to respond to any of it. The sound of scraping stone echoed through their small air pocket, little particles of dust falling on the top of their heads - the roof above was slowly sliding down! “Sh…shit! Okay Spike, there’s no time, just hold on to me, okay? I’ll get us out of here…” There was no time to admonish Spike further for his antics, or to figure out why the dragon was seemingly overcome with a bout of horniness. These questions would have to wait for when they were safe - and while Spike’s clutches made Twilight uncomfortable, she knew she could deal with them until they reached some real dry land. She started taking deep breaths in and out, the dragon still casually resting on her breasts as her chest rose up and down. “Mmmm…even your breathing is hot…” Spike said, before he himself noticed the lowering roof. “I…I can ride you…I mean…ride on your back then, Twi?” he continued, seeming very calm at the incoming danger. “Yes, Spike, but hurry, fill your lungs!” Twilight replied in panic, as the descending roof brushed against the top of her head, starting to push her down. Spike did not share Twilight’s panic, almost casually clambering around her body to grip onto her shoulders, again letting his shaft nestle between the pony’s ass cheeks, and letting a hand curl over her shoulder and grip the top of her breast. “Okay sweetie…I’m ready…” Twilight didn’t even have time to respond, taking a deep breath and letting the roof come down to submerge her fully. Had Spike even gotten a proper breath? It was clear this place was having some kind of effect on him - already Twilight could feel him starting to wander with his hands again - all the more reason why Twilight had to get them out of there. She made no attempt to stop Spike’s hands from wandering, and simply swam quickly down the flooded tunnel once more. Spike, in fact, had gotten a decent breath before they submerged. But it didn’t take long into the swim for him to start moaning out trails of bubbles as he pressed his naked body onto Twilight’s back. “Mmmmblglblblb…..” The voice in the back of his mind, the one telling him that he was being wrong and creepy, was barely audible any more. Even the part telling him that he needed to keep his air in his lungs was getting quieter. He quickly slipped his arms under Twilight’s armpits, gripping onto her breasts from behind and pressing his shaft against Twilight’s asshole, bubbling out air with every movement. Twilight blushed intensely but kept swimming as strongly as she could, not wasting any time trying to block the dragon’s advances. The next curve in the tunnel revealed a long, murky stretch, Twilight barely being able to see the end of it, and with no further air pockets to speak of. She pressed on with gritted teeth, wanting to get the horny dragon off her back just as much as she wanted to get them both to air. Even with still mostly full lungs, her face glowed bright red, giving tiny whimpers every time she felt Spike’s shaft press up against her asshole, and the clutch of his hands on her breasts. Meanwhile, Spike felt like he was in heaven. He barely even realised he was underwater, or that his air was already leaving him in long trails. All he saw was Twilight’s naked body, jiggling and swaying in the water as they moved forward. He was just irritated that he could only see it from the back - but his wandering hands were getting more than enough action on her front, his soft gropes of her breasts now turning into harsh grabs, even giving her sizeable nipples little pinches. “Mmmpphhlglglbbb….oohhgglblblb….Twiglighlntlblblb….” He made barely any attempt to keep air in his lungs, tightening his grip on Twilight, his cheeks starting to bulge and turn red. His shaft stayed nestled between Twilight’s flank cheeks, the tiniest little trail of pre-come leaking from it and into the cave’s waters. “Stoglbp itglglbbl!” Twilight bubbled out a command to Spike, jerking and shuddering as she felt her nipples be played with, but she knew Spike was deaf to any reason right now. She had no idea what this temple was doing to him, but she knew she had to get them out before it got any worse. As much as she knew Spike wasn’t in his right mind, she wouldn’t hesitate to use force against him if he got too gropey - though she was acutely aware that the grip Spike had on her was stronger than she expected. “Mmmpphhhglblbb….” Spike’s next moan wasn’t entirely of pleasure, containing a little whimper of discomfort - already he had burned through a lot of his air, so enraptured by the pony’s naked body in his grasp. He started to give soft thrusts of his hips, letting his shaft stroke up and down between Twilight’s ass cheeks, and starting to give the back of her neck small kisses and nibbles. But his slight humps were joined by slight heaves of his chest on Twilight’s back. Not that the young dragon had even noticed. “Mmmph!” Twilight just kept on swimming with gritted teeth, trying her best to ignore the dragon’s actions. After another twenty seconds of awkward swimming, the murky end of the tunnel started to become clearer, showing a massive void of empty water ahead. Twilight’s eyes widened, seeing that the tunnel was actually coming to an end, that they would soon be able to swim up, perhaps to their escape! But her elation disappeared quickly when she cleared the tunnel’s exit, and she looked up to the surface above - or at least, to where it should have been. All that could be seen as she stopped and craned her neck upwards was water, water, and more water. How deep were they? How far away was the surface? “Mmpphglblb….GLBBB!!” Her bubbly murmur of concern was instantly replaced by a large glub of surprise. As she had stopped dead in her tracks, the full weight of Spike’s body pressed up against her back, the dragon’s shaft pushing hard against her asshole, sliding just a little into the opening as Spike gave a bubbly yelp of pleasure. “MMMMPPPHGBLBLB….” He pulled his hips back to thrust in again, but Twilight had reached her limit. She gripped the dragon's arms and ripped his hands off her chest, spinning quickly and pushing him away. “STOGLBP ITGLGLBBL!” She once again tried to yell her command to Spike, letting a massive cloud of bubbles leave her lips, and stared down the young dragon with a stern stare, blushing and covering her chest and pussy. Spike hung there in the water, still bubbling in pleasure, looking at the bashful pony and reaching to his shaft, starting to softly pump it. But despite his pleasured expressions, it was clear his body was struggling, his chest heaving and stomach twitching, and a tinge of blue entering his face as the column of bubbles leaking from his lips shrunk to a small trail. He didn’t care about air, or about escape. He just wanted Twilight to himself - every little bit of her. With a grin, he slowly started to manoeuvre over to her…before being interrupted by a painful convulsion in his stomach, sucking in and showing the tiniest outline of the dragon’s rips. “MMPHGLBLBL! GLLBLB! MMMPH! HNNG!” It seemed like Spike’s mind had now finally realised his need for air and ranked it above his horniness, as one of his claws gripped at his stomach in pain, the other clamping over his mouth as he doubled over and flailed his legs. Weakly, he looked up at Twilight, pointing at the hand clasped over his face - he needed more air. Twilight hesitated for just a second, still angry with the dragon for taking advantage of her - a tiny part of her wanted to refuse the dragon and just swim up without him. But, when she saw the pained expression of her beloved Spike, saw him struggling in the water with near empty lungs, she relented. She knew Spike wasn’t in his right mind. It wasn’t his fault. She gave a quick nod, uncovering her sensitive spots, and leaned in as the dragon moved his hand from his lips… THHNNNGGGG. Another reverberation rang through the water just as their lips touched. Quickly, Spike’s need for air was fulfilled, but as soon as the water trembled around him, all that was on his mind was Twilight’s naked body, pressing up against his as he greedily sucked the air from her mouth...and he just couldn’t help himself. In a flash, he brought a hand up to the back of Twilight’s head, roughly gripping her mane and pushing her face against his as his other hand quickly moved between the pony’s legs, starting to stroke and grope her folds. “MMMPPHGLBLB! NOOGLNLNLNL! HNNGLNLNLBLBLB!” Twilight’s eyes widened as she tried to wrench her head out of the kiss, bubbles leaking from between their lips, but Spike’s hand held her there tightly, her hips bucking away from Spike’s hand. She tried to push the dragon away, but her pushes were weak, and Spike had gained strength far beyond his years - another side effect of this strange place? Twilight had no time to theorise, now forgetting all about their escape, and just trying to get this horny dragon off her. Spike didn’t relent, even as Twilight moaned and struggled, as she yelled out bubbly pleas of mercy. He let his tongue slide into the pony’s mouth, letting them sink to the bottom of the huge flooded cavern, sinking down to the bottom as Spike moved them into a horizontal position, Twilight’s back finally hitting the cavern’s floor, Spike briskly gripping the pony’s wrists and pinning them to the hard stone. He broke the kiss and raised his head, looking down at the naked Twilight and straddling her hard. “SPIKGLBLLBE! PLBLEAGLSE! NOGLBOOGBLBL!” Twilight locked eyes with the dragon, frantically shaking her head, trying to wrench her hands from the dragon’s iron grip, but it felt like she was shackled to the floor with chains, only being able to twist and jerk her hips, her legs kicking ineffectually behind Spike. Spike just simply smiled, leaning down and giving soft kisses all over Twilight’s bare chest. “Mmmpphhglblblb….” Twilight whimpered as the kisses became more passionate, Spike’s tongue running all over her breasts, and she gave a bubbly yelp as his lips wrapped around her nipple, giving it a firm bite. All the while, despite Twilight’s attempts to evade it, Spike was moving his hips - and his engorged, twitching cock - to line up with Twilight’s lower lips, the head of his shaft starting to prod and poke against them, the dragon burbling with pleasure every second he spent toying with his housemate. “Mmmmmpphhglblbl….ohohoglbllbllbb….Twiglblighglbt…” As he finally positioned his dick ready to thrust inside her, he simply looked at Twilight with an aroused grin, air freely leaking from his lips as his face turned red once again. Twilight shook her head more frantically, tried to jerk herself out of his grip, tried to lock eyes with him one last time with a pleading look - but nothing swayed the dragon from his course. He let go of Twilight’s wrists, pushing his hands into her chest and groping her breasts hard, and finally did what he had wanted to do from the very beginning - thrusting his hips forward and pushing his shaft harshly between Twilight’s legs, sliding it inside her. “OOOOHGLBLBLBLBLB!” “NOOOOOGLBLBLBLB!” The two moans that rang out could not have been more different - Spike’s a burbly moan of pleasure, Twilight’s a bubbly wail of disgust, feeling the dragon’s dick push inside her pussy. With her free hands, she tried to push the dragon off, weakly slapping and punching through the water, but Spike was impossible to stop, starting to hump his hips back and forth, fucking the pony’s pussy hard and fast, giving a bubbly moan and grunt with every thrust. Twilight kept trying to fight him off, but Spike was like a lead weight on her body, and her struggles and kicks were only serving to turn Spike on even more, as he pushed himself harder and deeper inside the pony, barely making any effort to keep his air in his lungs, the clouds of bubbles already getting smaller and smaller with each grunt he made. “MMMPH! HNNGLB! BLBL! HNNGGLBLB!” Keeping a strong hand planted on Twilight’s chest, he leaned down to force his lips on Twilight’s, the pony trying to wrench her head away, but the dragon’s other strong hand kept it facing forward as he harshly locked lips with her, sliding his tongue down the pony’s throat. “MMPPHGLBLGLBMMMPGHHH!” Bubbles shot out of their interlocked lips, not a drop of it being shared, as the heaves and twitches of Spike’s struggling body simply made his thrusts more frantic and speedy, dust raising from the stone floor of the cavern as he fucked the pony with reckless abandon. Twilight still tried to stop him, but noticed his body starting to heave - maybe her only hope was to simply outlast him, but it was hard to keep her own air in with all that was happening to her. “MMMPPHHH! GLLLBLBLB!!!!!” Despite the primal urges going through his body, Spike couldn’t ignore his need for air forever, and finally with a harsh heave of his chest, he leaned up, breaking the kiss and bringing a hand to his own throat, cheeks puffing up like balloons, tinged with both red and blue, but still with a hand firmly on Twilight’s chest, still pumping his shaft hard and fast inside her, little tendrils of pre-come leaking from Twilight’s pussy. Even he started to shake his head now, but all it took was one more look at the struggling Twilight underneath him to make him forget the peril they were in… “Hnngg….mmmpphhh……ooohohglblblbl…..BLGLLLGLBBBLBLGLBLBLBLGAAAHGGLBLBLBLBLBL!” Clamping his hands on Twilight’s shoulders and pinning her down even harder, he started to mindlessly fuck her even harder still, giving a loud pleasured moan as he screamed out all of his air in one large column, feeling his orgasm start to build in body, desperate to come before his air ran out. Twilight’s struggles had slowed, as she tried her best to lock her lips shut, to keep as much air as she could, but the dragon’s thrusts were starting to get painful now, and she whimpered and yelped out small clouds of air with every thrust of the drake’s shaft. Spike kept up the pace even after his own air ran dry, now giving airless grunts as he gritted his teeth and locked his lips tight shut, face nearly completely blue as his heaving, convulsing body showed there wasn’t a hint of air left in his lungs, stomach pulsing in and out hard, his ribs nearly fully visible under his scales. He felt the water leak into his mouth, looking at Twilight ravenously, praying that he could come before he started sucking the water down… “MMMPHH…..MMMPH! HNNNG! MMMMMMMMPH…..hrk….glk!” …but, they practically happened simultaneously. With one last powerful thrust, the dragon came hard inside Twilight, filling her with his seed, just as his mouth opened and coughed and spluttered on the water. Twilight squirmed and writhed, shuddering as she felt Spike’s come fill her insides, but also looked in horror at the dragon start to choke on the water, the blue and red in his face combining to make a deep purple much darker than his scales - yet even so, he continued to fuck the pony hard and fast, gulping and choking the water down as he thrusted as deep and as fast as he could, riding the high of both drowning and coming, eyes locked shut and mouth open wide as his tongue flapped out, his deep moans of pleasure muted by the water filling his mouth and throat. After what seemed like an eternity, the dragon finally started to slow, giving the pony’s pussy one last weak thrust before finally sliding out of her, strings of come leaking from both his shaft and her pussy, as he gave a gurgly growl of pleasure. “Mmmmmmnnnggg….hrk…..glkk…..glbhkk….” Even while he choked on the water, he looked at the pony beneath him, and gave her a wry smile…before one painful heave finally brought the water straight into his lungs, and his eyes opened wide, clamping two hands to his throat to try and stop the water, but it was far too late. His chest and stomach heaved as he inhaled the cavern waters deeply, his brain finally realising that he needed air, as he kicked off the cavern floor weakly, taking a hand from his throat to claw for the surface, legs kicking weakly, but he barely moved at all. Twilight kicked off the cavern floor too, cheeks red and bulging as she watched the dragon struggle, seeing him choke down the water, his hard shaft started to soften as his movements got slow and pained - and for just a split second, he locked eyes with Twilight, looking at her in fear and confusion, weakly reaching out a hand… “MMMMPH!!! SPIKEGLBLBLBL!” Twilight shot into action, gripping the dragon tightly in her arms and kicking up towards the surface. Despite all she’d been through, she knew deep down that it wasn’t Spike’s fault. She needed to save him! But still, the surface above them wasn’t even visible, and Twilight’s chest and stomach were starting to heave too, as she kicked as hard as she could upwards, one arm wrapped around Spike and another clawing for the surface, Spike’s limp body weighing her down. “Hnngg…..hrk……glk…….blb….” Spike simply hung limply in Twilight’s grasp, his weak kicks adding nothing to their progress, as his deep breaths of the water started to get shallower and shallower, now no more than pained hiccups of the water as his eyelids fluttered and his vision started to go dark. He hazily looked up at Twilight as she tried to get them to safety, before his head flopped down to rest on her chest, weakly choking and gurgling, his body twitching against Twilight’s. “MMMMPH! GLBLLLB…..hnnGLBLBLBLLB!” Spike’s body was just getting heavier and heavier in Twilight’s arms, and it wasn’t long until a convulsion of Twilight’s stomach stopped her in her tracks, glubbing out a cloud of air painfully as she clamped a hand to her mouth, still keeping Spike held tightly. She gave him a small shake, trying to keep him awake, but his head simply flopped back, his chest and stomach convulsing one last time as he choked down one last breath of water, before shuddering and twitching, going limp in Twilight’s arms, eyes glassy and lifeless. Twilight’s eyes widened as she tried again to reach the surface - it was finally in view - but without a hand to cover her mouth, her air quickly left her lips in clouds and columns, her puffy cheeks deflating quickly, her arms and legs aching and cramping as the full toll of the ordeal finally hit her body. Her speed slowed to a crawl, eyes still locked on the surface so far away. “MMMPHHH!!!! NNNOOOOHHLGLBLBLBLLLBLBLBLBL!!!!” One last surge of adrenaline hit her as she frantically and desperately clawed for the surface, screaming her air away as she swam slower, and slower, knowing she would never reach the surface in time. Her chest heaved hard again, a massive cloud of air exploding from her mouth as she let Spike go to clamp both hands to her mouth, doubling over in pain, Spike’s drowned body starting to sink a little below her. She quickly reached out a hand to grab his, still valiantly trying to claw for the surface, but the last trickles of air leaked from between her blue cheeks, water leaking into her mouth as she tried to spit it out and grit her teeth, trying to drag the dragon’s limp body up with her…but it was no use. “MMMPPH…..HNNNG! GLKKKKK!” The most painful convulsion hit her stomach hard, as it sucked in, bringing with it a painful breath of the water. Twilight let go of Spike again, clamping both hands to her throat, splitting and coughing on the water, survival instinct forcing her to weakly kick her legs even as Spike’s body started to sink out of reach, but every painful inhale of the water made Twilight feel heavier and heavier. Even as she took her hands from her throat and clawed and kicked for the surface in a mad panic, she barely moved upwards in the water, her naked body swaying and twisting as the pained look on her blue face started to slacken, her vision blurring, her movements getting slower and slower. “Glbnnggg…….hnnngggg…..glk……….hng…..” The flailing of her limbs turned into a weak flapping, before barely moving at all, as she finally started to sink along with Spike, taking deep breaths of the water, her eyelids fluttering as she sank and breathed for what felt like an eternity. Eventually, she felt the cold stone floor of the cavern once again, laying there with arms outstretched towards the surface, giving one or two more choked breaths before her lungs filled to the brim. Her head fell to the side, her blurry vision just making out the motionless body of the drowned dragon slumped on the cavern floor, and with a few weak hiccups, her vision faded to black, a few errant twitches coming from the bodies of both pony and dragon before they hung motionless on the floor of the cavern.
