The flooding hour

Finally home after a long day, Chomper, a blue and quite chubby anthro t-rex, flopped nude onto their bed. So many people had been insufferable today, especially that damn Littlefoot. Who cares if he was shorter than them, he was still clearly better!
With a heavy sigh, the rex closed his eyes. Surely, someday, those idiots would see it his way. Littlefoot, Rhett, Shorty... A bunch of other people he didn't feel like naming... He'd prove to them, someday, that he was the best. He just needed to do something big, something that would finally give him the respect he deserved. But what?

The next thing Chomper knew, it was night. He'd fallen asleep while trying to think of a way to one-up his rivals. "God damn it, there goes my sleep schedule..." He looked over at the clock: 3:02 AM. Continuing to lay in bed for a while, trying to get back to sleep, Chomper eventually heard what sounded like distant running water. "...I didn't leave a tap on... What the hell?" He lived alone, as well, so it wasn't like someone else had turned something on.
As he got out of bed to check what was going on, there was a splash; he was up to his knees in water! "Oh, for the love of... Wait..." Chomper had a fairly big house, and his bedroom was on the second floor. Looking out the window, nothing out of the ordinary was happening outside, and there was no possible way the ground floor and basement had entirely flooded.
"Ah, good, this is a dream." With his fear assuaged, the dino turned on the light, squinting for a moment. The water level was steadily climbing, overtaking his bed by now, and soon requiring Chomper to swim. He smiled and splashed the surface for a moment, before letting himself sink under, not even getting a breath first. His room looked strange like this, several things floating a bit off the floor. Quickly realizing he was instinctively holding his breath, he blew some bubbles and opened his mouth to inhale-
"KAGLURGL!" The water caught in his throat, and he immediately coughed it back out. This wasn't a dream! He scrambled to the surface with a few more coughs. "Fuck, this is real! How the hell is this actually happening!?" Swimming over to the window, Chomper tried to open it so he could get out, but it seemed to be stuck somehow. He'd last opened this a couple days ago, and pretty easily too, so this didn't make sense! The dino pounded on the window in an attempt to break it, but that wasn't working either.
With the water just a couple feet away from the ceiling by now, Chomper swam over to the door, diving down to reach its handle. After a moment of figuring out how to brace himself properly, he got it open, and darted back up to the surface to take some deep breaths and get ready. He did sort of have a plan; try the rest of the windows, and the front and back doors. If those were somehow all stuck, he'd grab his scuba gear and figure something out from there. It was interesting to think about that gear actually being used for something practical for once; he'd only ever used it before when he was messing around in the bathtub.
The last inches of air were going away, now, and with one last breath through his nostrils, Chomper watched the water reach the ceiling. Not wasting any time, he swam throughout his flooded house, trying window after window to no avail. Each faucet he went past along the way was fully on, the drains blocked, but that couldn't possibly send out enough water to fill his entire house in just a few hours! Even if given a ton of time, the water would just leak out, but that wasn't happening here. Someone must have sealed him inside! It was probably Littlefoot, that jackass... This was certainly an elaborate way to try to get back at him. Of course, once Chomper got out, having survived this would be exactly what he needed to finally prove he was the best!
After trying both doors and confirming they were stuck as well, the dino had been holding his breath for 4 minutes. He was still fairly calm, with his breath holding record being 14 minutes, though he was feeling the need to breathe by now. With the last of the windows checked, and still no immediate way out, Chomper rolled his eyes. Scuba it is, then. Maybe I could actually sort of enjoy this for a while with that, too?
As he started swimming down to the basement to get his scuba gear, it occurred to him that some things around seemed... Out of place. Sure, the flooding might've knocked some stuff around, but there were things that were quite far away from where he'd left them. Case in point; one of the chairs from the first floor seemed to have fallen all the way to the basement somehow, and one of its legs had come off. How the hell did that even happen?
Taking his mind off that for now, Chomper continued through his basement to the closet where he kept the scuba gear. And, its door was stuck too. Ugh, this just can't be fucking easy, can it? Bracing like he had with the other doors, he pulled and pulled, but the door wasn't moving. Now, he was starting to freak out again; if he couldn't get this door open, he was going to have a lot less time on his hands. N-no, don't tell me they knew about this!
He tried harder and harder to pull the door open, and it still wouldn't budge. Adjusting himself to brace more effectively, he yanked with everything he had-
And the door flew open, as if it hadn't even been stuck in the first place. Chomper was launched backwards several feet from his unexpected success, flipping over before quickly righting himself. He gave a smug smile; whoever set all this up was going to be pissed. Except, the scuba gear wasn't in the usual spot. The dino looked all through the closet, burning another minute, but it just wasn't there. Cheeky fucker moved it to waste my time! He could almost hear Littlefoot's distant laughter at this.
There was nothing for it; he'd just have to look around the house for his scuba gear. The rest of the basement had no sign of it, so he started to return upstairs before pausing and looking back. He'd passed the chair again, and its broken off leg was definitely in a different spot. Wh... Oh, that fucker's here, isn't he!? They were probably using his scuba gear, too!
Paying no mind to the fact that there weren't any bubbles that would've been left behind by it, Chomper angrily swam up the stairs back to the first floor. Another few minutes passed as he searched, and his anger slowly gave way to fear, his breath hold closing in on the double digits in length. He still hadn't found anything, not his captor nor his scuba gear, and his cheeks had grown to half the size of his head. Pausing for a moment, the dino covered his mouth as he tried to think of where he hadn't checked, before hearing something fall in the bathroom. Got you now, asshole! He could see the side of its doorway from here, so there was no way someone could get out without him noticing.
Bolting straight for the bathroom, he found... No one. One of the decorations had fallen. "Gobld DABLMN- Mmg!" Chomper covered his mouth to cut his outburst short. He couldn't be wasting air on talking to, apparently, no one. But then, how did that chair leg move if he was alone? He didn't think about that for long, as it turned out coming to this room wasn't a complete bust; his scuba gear was here! Strangely, it was precariously perched on its side on the edge of his bathtub, but Chomper was finally in the clear.
When he reached for the regulator, the tank happened to fall to the floor, rolling because of the bathtub's rounded edge and going for the doorway that happened to be across from it. Oh, come off it, how does an object know to be annoying? He chased after it, but it was going surprisingly fast and didn't seem to be slowing down, barely outpacing him.
Then, the tank turned. Not a small amount like if it had rolled over something, but nearly 90 degrees, rolling off into another room. Chomper stopped and watched it, and things finally clicked. ...Littlefoot didn't do this. There's a fucking ghost in here. As he came to that conclusion, he heard a distant chuckle, as if it was reading his mind. It was similar to the laugh he thought he'd imagined before, as well. That closet door taking so much effort to open, until it suddenly didn't, had to have also been this thing's doing.
Without really having any other option, Chomper continued going after the scuba gear, which just kept rolling away from him. He realized pretty quickly the ghost was just messing with him and wasting his time, and while he didn't have a whole lot of that left, he continued to play along, hoping the ghost would eventually be satisfied and let him breathe. The chase led him all over the house, with the gear even rolling down stairs and floating up them - because of course it was. It would dart past him faster than normal whenever he managed to corner it, always managing to keep out of his grasp.
Eventually, Chomper had been holding his breath for 13 minutes, and while he wasn't yet at his record time, all the exertion from the ghost's "game" had brought him to his limit. His huge - and now purple - cheeks kept him from following the scuba gear into the next room, smooshing against the door frame, but he couldn't swim any more anyway. Covering his mouth, the dino thrashed as his lungs burned, and he ran entirely out of breath.
"MMBLARGALBL!" A cloud of bubbles was shot out as his lungs gave up, but Chomper didn't inhale just yet, closing his mouth again and grabbing his neck. He was entirely empty of air, not even able to puff his cheeks, and he frantically looked around for any sort of air source, assuming the ghost still didn't want to give him any. Except, as he sank down to stand on the floor, something bumped his foot. The air tank! Not only that, but the regulator was being held up toward him, finally giving him a chance to breathe.
Not hesitating, Chomper grabbed the regulator and shoved it in his mouth, and just in time, as he finally instinctively inhaled. "FSSSS-GLP!" He finally got his badly needed air, sure, but then the regulator was pulled away again, and he only barely managed to swallow the water he ended up sucking in. It seemed the ghost wasn't done with him just yet, as the air tank started rolling away again.
While he was doing much better now, the dino's lungs still burned and he couldn't keep himself from bubbling, so he didn't have long until he'd just be back on the edge of drowning. As annoying as it was getting, entertaining the ghost was the only thing keeping him alive, so he once again swam after the scuba gear.
This time, it seemed it had something different in mind; the purge button on the regulator clicked in, and a thick trail of bubbles was being left behind as the air tank continued rolling. Chomper briefly panicked before he figured out what it intended; the ghost wanted him to inhale the bubbles instead of breathing directly from the regulator. Swimming up to the ceiling, he opened his mouth and caught what air he could, carefully inhaling it every now and then. This definitely wasn't giving him quite enough air, as he missed most of the bubbles, but it was letting him last longer than he thought he was going to.
As he slowly grew more desperate, Chomper accidentally sucked in too much, some water getting into his throat. He gulped, then coughed, and barely held back from inhaling by continuing to drink. Thankfully, once again, the ghost let him breathe, raising up the regulator and letting him grab it. Though he got a bit more air than last time, it still wasn't enough, and the regulator was soon pulled away again, the dino not needing to gulp water as he'd expected it this time.
Then, of course, off the tank went, thankfully not spewing out bubbles. Another round of "Chase the air tank" it was. Chomper only hoped he could hold out through these until the ghost got bored. But, when he followed it into the next room, the storage room, it became clear that things would be quite different this time.
The door closed behind him, and he already knew not to bother trying to open it. There was that laugh again, and the two coils of rope laying about the room started to move! Interestingly, they were acting like snakes, "slithering" toward Chomper at an unnerving speed. Of course, the ghost was definitely behind this, and wanted to tie him up, but also wanted to have some fun with it.
This room's ceiling wasn't very high up, so the dino couldn't swim up to avoid the ropes, but it probably wouldn't have helped anyway. Whenever they'd get close, they'd lunge at him, and he'd only barely be able to dodge because of the water's resistance. It wasn't long before one of the rope snakes got onto him, and it immediately started coiling around him. He quickly pulled it off, but just as he managed that, the other rope caught him. While he kept removing them as fast as he could, they seemed to be speeding up, getting farther along him each time, until finally one of them caught his arms. It was over at that point, and within a few more seconds Chomper was completely tied up, barely able to move. The part around his hips shifted, letting his hard cock flop out and exposing his butt. He hadn't noticed until now, all this time underwater and being toyed with had gotten him rock hard.
Just that movement was enough to tell him what was going to happen. With head-sized cheeks and a heaving chest, he watched as his box of sex toys opened up, one of his bigger dildos floating toward him. While it wasn't like he couldn't take it, this wasn't the time! If he came, he was going to lose a lot of air, and it wouldn't be long from there for him to start drowning!
He squirmed what little he could, but there was nothing Chomper could do. The dildo got to his butt and shoved itself inside, up to the hilt. "HMMGH!" Bubbles burst out from his nostrils, and he tried his best to keep from losing more, unable to cover his mouth or pinch his nostrils. The ghost started fucking him with the dildo, and while it still felt good (and part of him did enjoy this), he still struggled to get loose as his lungs burned.
About 30 seconds later, Chomper was fighting to both hold his breath and not climax, still struggling in the ropes and now rebreathing in his huge cheeks. Soon enough, his arousal hit the point of no return, and as much as he tried to hold it back...
"PLBALABL-HUULP!" He came hard, losing nearly all his air and involuntarily gasping, though thankfully managing to swallow like before. A few more bubbles spurted free with each shot of cum, and Chomper shivered as he tried to hold what little air he had left. Barely even able to puff his cheeks, he looked over at the air tank with wide eyes, mentally begging for it to come closer. But this time, it didn't, and with a hiccup, he sucked in again, taking another gulp, and repeating as he just barely held off from truly inhaling. He could feel his belly expanding as he drank, pressing against the ropes that refused to budge. Unfortunately, this final effort didn't last long.
"HIC-ULP, HIC-GLP, HIKHUUUAA!" One of his slurps hit its mark, finally getting into his lungs. His struggles increased even further, frantically shaking his head (since it was all that could still move) and loudly choking. Suddenly, the ropes fell away, although the dildo stayed in his ass, and he could finally move. After a moment of kicking and clutching at his neck, Chomper remembered the air source in the room and bolted for it, praying that the ghost would let him have it. Thankfully, it did, and as he held the regulator he hacked up as much water as possible to make room in his lungs, before finally getting a proper breath.
"FSst" Except, he didn't. The tank's air had nearly run out from all the bubbling earlier, and what he got was barely anything. Not only that, there was still water in his lungs, and it took everything he had to not cough. There was another laugh from the ghost, having been fully aware of the air tank's state, and some gurgling from Chomper, trying to hold his breath with partly flooded lungs. As he struggled, he began feeling his dick being stroked. It wasn't him doing that, so it had to have been the ghost messing with him some more. While he wasn't going to be cumming again so soon, it was making it a bit harder for him to focus.
With likely only minutes left for him to live, the drowning dino scrambled out of the storage room, thankfully now able to open the door, and began searching the house one last time, but he wasn't really sure what he was looking for any more. It felt awful to swim, he could feel the water sloshing in his chest, and he couldn't help but let out a tiny cough, sending nothing but bubbles from his nostrils. No matter where he went, he was continuing to be masturbated by the ghost, the pleasure from that making this at least slightly better. Swimming up to a window, he tried harder to break it, but lacking oxygen to such a degree was weakening him and making it hard to focus, his strikes being uncoordinated and completely ineffective.
His cheeks sucked in and pushed out as he tried to rebreathe again, but internally breathing while partly flooded just made it worse, and he coughed heavily and proceeded to gasp again, going right back to choking. Chomper frantically beat on the window with one hand while grabbing his neck with the other, scanning the outside for anyone that might've happened to be there. "H-HEKHLP MME! SKH-SSOMEHUUONE!" But, no one was around, and the only one to hear his gurgled plea was the one who got him into this in the first place.
It occurred to Chomper what he should be looking for; surely some air was still trapped somewhere. He swam off again, tearing through drawers and cupboards, and did indeed find a few bubbles, though gasping them down did nothing to help him at this point. By now, he'd had water in his lungs for 2 full minutes, and while an extreme lightheadedness was taking hold, the dino continued ransacking his house for as long as he could.
He paused for a moment, humping at the water, about to cum again thanks to his invisible partner. Trying to stop it was pointless, even covering his cock entirely not impeding the ghost, and his second orgasm came. Still trying to block off his dick, he gurgled painfully as he came against his hands, then relaxed for a moment as his orgasm faded fairly quickly. Then, with another choked cough, he shot back to awareness and his struggles continued. The ghost had stopped masturbating him now, though he wasn't quite sure whether or not to be thankful of that.
Another minute of pointless searching, and Chomper's struggles started to slow. He tried to keep swimming, but the growing weakness and the extra weight were making that increasingly difficult, and he soon resolved to just walk instead. Even that was difficult, but leaning on walls and furniture made it a little easier. Going back down into the basement, he somehow managed to get down the stairs without falling, only to trip on the chair that had fallen down here earlier. The impact stunned him for a moment, and when he could think again, the intense dizziness was starting to make him delusional.
By the time he'd gotten back to his feet, he'd entirely forgotten the situation he was in, even that his house was flooded. He looked around the room he was in, then back to the stairs, seeing the broken chair. While he still recognized it shouldn't have been there, he didn't notice the snapped off leg any more. ...hhow the helll did thiss... Picking the chair up, he hiccupped and started the trek back up the stairs, going at a glacial pace even as he held onto the railing.
Getting back to the first floor took nearly 30 seconds, and Chomper set about putting the chair back in its rightful place, which thankfully wasn't too far. He set it down roughly where it should've been, the chair facing entirely the wrong way and immediately toppling over. ...thherewe ggo... Now, what was he about to do before he'd gotten sidetracked by that?
Looking down at himself, he realized he was nude - a little more blue than usual - and fully erect. That was what it was, he was going to have one of his bathtub jackoff sessions. Blearily looking back up, he trudged on over to the bathroom, the tub already full and waiting for him. It took him a few tries, but he stepped into it and sat down, taking deep breaths of (what he thought was) air before laying down and holding his breath, puffing his cheeks to the size of his head.
He looked up at the "surface" for a moment, imagining bubbles leaving his nostrils, before fumbling for his dick and starting to stroke it. Unbeknownst to him, the dildo the ghost had fucked him with earlier was still in him, and it simply being there made this feel a bit better than usual. Or maybe that was the lack of oxygen? Chomper didn't notice either of them, content to relax and think that he was blowing bubbles.
For a moment, he shuddered and his movements slowed, his consciousness starting to falter. Of course, all the waterlogged dino thought it was was that the power flickered. ...ffuckin p...ppower... It probably wasn't going to matter, but it was definitely still annoying. A few seconds later, he had another brief blackout, waking up with a hiccup he believed to be a heave of his chest asking for air (which, technically, it was). ....nnot yyet...
"...nnmghl..." Chomper's arousal started to surge as he pushed himself to the edge of an orgasm, trying to use both hands to make it stronger. When it finally happened, it was weak and barely sent out any cum, but still felt great. "...nnguuuhhh..." He moaned as best as his exhausted body could, and shuddered again as his eyelids started to slide shut...
And, finally, he remembered what was happening. "GHKH!" Once again, he choked hard, and forced himself up out of the tub, having no idea why he was there. He briefly fumbled with the doorknob, his body having gone mostly numb, before realizing the door was already open and swimming out of the room. Frantically looking around before swimming up to a window, he banged on it again, his calls for help now being entirely unintelligible.
This last struggle didn't go on for long, Chomper slowing down again until he was as weak as he'd been on his trip to the bathroom, then weakening even more, slumping against the window. All he could do was breathe the water, until he was too weak to even do that any more, and soon, at last, he couldn't stay awake any more, drifting into a waterlogged sleep.
The ghost laughed once again as it saw the dino pass out, proud to have accomplished its mission with plenty of time to spare, and having had quite some fun with it as well. It pulled Chomper's body from the window to mess with it for a while and pass the time, until it hit 4 AM. The ghost willingly let itself fade out, their influence over the house disappearing as well; torrents of water gushed from the window and door frames as the house drained, leaving the drowned dino's body on the slowly-drying floor.
