The slide by the sea 5 By Strega

Otters are good at digesting fish. Extremely carnivorous, their potent stomach acids and short digestive tract are tailored to process meat quickly and relatively efficiently. Insert a fish at one end of the otter - most otters dice their prey up with their sharp side teeth, but a rare few swallow it whole - and in roughly an hour it will appear from the opposite end of the otter, naturally having changed somewhat in appearance.

A really big sea otter like the one in question might swallow an entire human, and that's a bit trickier to process, but there's still room around the stretched-out meal for the acids to pool and churn. It took the big otter a day or so to digest and pass such a meal.

But he'd never swallowed something as large as his recent sea lion meal and digesting it proved something of an adventure. The thin layer of gastric juices trapped between the sea lion's hide and the otter's stomach wall worked on it only slowly and the only place any real progress was made was at the bottom end of his stomach, where acid was able to pool around the slightly narrower neck and head. A churning vortex of caustic juices developed there and the sea lion was digested headfirst, just as he'd been swallowed. By the end of the first day the head and neck dissolved away and the lower body and rear flippers, previously stretched out in the otter's gullet, finally were able to slide into the water-weasel's long stomach to get their turn at digestion.

What started out as a long, somewhat lumpy bulge where the bony structures of the sea lion swelled out the otter's fur slowly became a shapeless swelling over liquefied flesh and softening bone. This in turn began to shrink as the remains of the sea lion made their way through the big otter's intestinal tract.

The whole process gave the otter a bit of a stomach ache and at least once an hour he paddled a little way out into the bay to relieve himself, for despite his body's best effort to turn all that sea lion meat and blubber into fat there was simply too much. He gained perhaps a hundred pounds on top of his previous six hundred as he digested his prey but the other five hundred pounds of sea lion were reduced to their base materials and expelled. Sea lion in, otter shit out - mostly. It took him three full days and part of a fourth before the bulky sea lion was fully digested, save for a few stubborn fragments of bone wedged into folds of his belly. Even these would eventually dissolve, or at least crumble enough to escape his body with the other indigestible bits.

The good news was that though there was an awful lot of sea lion to digest, at least it all digested. The same could not be said for certain things he'd swallowed. Humans dissolved just fine but not, usually, their clothing and other toys. A sock or swimsuit made its way through the otter without issue but not, for example, a pair of tennis shoes now minus their owner. None of that was a problem as the otter lay about and digested the sea lion.

After three and a half days of little exercise the otter was happy to return to the water but even now he was not hungry. It would be another day before the least nag of appetite rose and he'd put on enough fat to last many more if he chose not to eat. With little to do but laze around and wait for his appetite to return he was powerfully bored by the fourth day and very happy when the she-dolphin poked her beak from the waves.

"You're thinner," she chittered without preamble. "But also fatter."

The otter grinned. He'd been able to return to the rocks to sun himself when the long lumpy bulge grew soft enough but he slid back into the waves to join the dolphin. Just the same he was cautious enough to duck his head under for a moment, ostensibly to wash sand off his whiskers but in reality to make sure he was alone. As someone who had just digested a sea lion whose chief mistake was to be too trusting he thought it wise to make sure this was not a trap. She, too kept a cautious distance, knowing full well that his last meal had been as large as herself.

Behind him the larger sea lion smiled. Not everyone was an enemy and not everyone was food. Though the otter had taught him to catch humans the water-weasel was younger than he was and he wasn't surprised to see his friend's thoughts turn to something besides eating. The otter was off to hopefully enjoy himself while he idled on the rocky outcrop, planning his next hunt.

When the otter surfaced he found the she-dolphin a body length away. "That's what happens when you eat a whole sea lion," he purred. "You put on some weight."

"Do you often eat sea lions?" she chittered.

"Only this one," he purred, feeling his newly thicker body with his webbed forepaws. A layer of fat now existed that a few days before had been a friendly, if stubborn and not too smart sea lion. "And only because he was causing trouble. My best friend is a sea lion, you know."

"So he wasn't your enemy?"

"Sort of," the otter said. "He was following us to our hunting grounds and taking prey there very incautiously. If even one human saw him eat and got away -"

She blinked. "You eat humans?"

"There are a lot of them," the otter purred. "And if you're careful you can eat them and still never run out. They think their kin are drowning or being taken by other humans instead of," he patted his long belly, "otherwise disappearing."

"So humans are your enemies," she chittered. The otter considered. Her relatively simple view of things probably stemmed from living in a group of allied dolphins. To a solitary predator like himself anything that could fit in his stomach was potentially prey, but not necessarily an enemy. You didn't have to hate someone to eat them. It helped to dislike them, thus the slimy digestive end of the sea lion.

"Do you often eat your enemies?" He purred.

"Yes," she chittered brightly. "Would you like to help me do it?"

"I would," purred the sea otter, who found himself liking her. She was different from the last dolphin he met, less stubborn but just as friendly. She was bright and chirpy and curious and entirely unlike his sea lion friend or the few other otters he'd met. She was also, of course, female, and her actions the last time they met made him think she might not be averse to some play not centered on a hunt. So he followed her until they reached the far side of the bay and she pointed with her beak.

"There," she chittered, her underwater voice little more than a whisper. "Shark. They eat dolphins sometimes, you know."

The otter kept his mouth firmly shut on the subject of who else might eat a dolphin and watched the shadow move through the water. The shark was smaller than the two of them, perhaps half his weight and eight feet long. Perfectly streamlined, even more so than himself and rivaling the dolphin, it was an engine of muscle and sinew designed to catch and eat. Just as he was, but from the water rather than the land.

"Scare it past the pillars," she chittered, and swam toward them herself. The 'pillars' were support legs for a pier, covered with mussels, sea anemones and the occasional starfish there to prey on the shellfish. With some idea of her plan he swam a wide arc to come around the far side of the shark and then approached it.

It sensed his presence at once and turned away, but he was nearly as fast as it was and with a burst of speed he managed to catch it. One of his clawed forepaws brushed its tail and its instinctive reaction was to thrash its hindparts and dart out of reach.

"Go away," it growled, in the brief and violent language of sharks. Its attention was on him as it swam away and that was a fatal mistake. It was at flank speed and moving much too fast to stop past a pier support when the she-dolphin appeared from behind it with her beak gaped wide.

The shark was unable to swerve aside in time and the otter felt a thump through the water as its snout slammed into the dolphin's maw. Familiar with the effects of momentum on feeding and having seen a smaller dolphin swallow an entire human whole he was not surprised when the front half of the shark simply disappeared into the dolphin's gullet. Nor was he surprised when she was not satisfied with just half.

As the shark thrashed its tail in confusion, or perhaps in an attempt to free itself from the fleshy trap it found itself in, the dolphin arched. First her wide-open beak went down and then up, a strong flicker of her flukes pushing her forward. Inertia held the shark in place and the sinuous motion of her body slipped her maw forward almost to the shark's tail.

She arched again, swallowing. A great contraction moved visibly down her smooth-skinned body as her gullet gripped the bulge, sending it deeper. The long bulge in her body twitched as the desperate shark tried to escape. It failed. One more gulp and the vertical tailfins folded and slid into the dolphin's jaws. Only the very tips remained outside. Apparently her stomach and gullet couldn't quite accommodate all of it.

"That was impressive," purred the otter, unknowingly echoing his sea lion friend. A strange bulge stood out of the dolphin now, the swelling on one side a different shape than the other. The muscular contractions of her throat had forced the shark deeper until it bent into an ess inside her. Only perhaps the first third of it lay in her stomach, the rest stretched out in her gullet, but she had it fully swallowed and now it was just a matter of digesting it. Like the sea lion the otter ate her stomach juices would consume its head and forebody, making room for the rest to slide into her gut. It was a strange and awkwardly bulgy meal but he'd had those too and was confident that given time the bulge would smooth out and vanish as the shark became dolphin food.

"Thank you," she chittered, just as the shark inside her wriggled. The otter winced as her whole streamlined body thrashed from side to side, propelled by the motions of her muscular meal. The shark very much wanted not to be in her, unaware in its brainless way that the only way it would get out of the dolphin was after a trip through her digestive tract.

He could see the bulge in her belly moving as the shark gaped, trying to get its sharp triangular teeth into her flesh. He'd never eaten a shark but that looked bad.

"Isn't that dangerous?"

"Only for the shark," she giggled, and yawned. There inside her mouth he could see more of the shark's tailfins, as far into her as they could go until digestion made room further in. She didn't breathe or talk through her mouth so it was no inconvenience for her, unlike him, who'd wheezed around a swallowed sea lion's tail flukes for hours. Likewise, there was no air to burp up. The shark had simply disappeared with no trace at all of its prior existence other than a bulge and a few inches of fin sticking out of a dolphin's beak.

He was cautious enough not to stick his muzzle in for a closer look. You never knew, after all.

"The walls of my throat, then my stomach hold its mouth shut enough that it can't bite me," she chittered, and he nodded. The same thing happened when he swallowed things like the sea lion.

"There are other things though," she said, and this time she was the one to wince as the shark wriggled inside her. "A shark's skin is rough, like sharp rocks. It scrapes you going down, it scrapes when they wiggle. And," she lowered her voice to a conspiratorial whisper. "It doesn't digest. All those little sharp bits scrape on the way out, too."

That made the otter grin. "Humans digest just fine, but their things usually don't. That's not a problem with things like the clothing they wear to the beach but I've had their goggle things," he gestured at his eyes, "Shoes, And even one of those foot fin things they wear go all the way through. I didn't enjoy it. And my sea lion friend ate a human recently who was in clothing from head to foot. Stopped him right up until it finally came out."

But back to the shark. "Why eat them if it hurts, though?"

"Because I don't like them," she chittered. "Sharks attack us, we attack them. A big shark swallowed my mother whole. I saw it happen. Now..." she stroked the long bulge with her flippers.

The ingested shark thrashed and the well-fed dolphin just giggled, though it threw her around in the water. It was struggling, still trying to escape. Barring a miracle there would be no escape. Struggle or not, the result would be the same, a trip headfirst through the bowels of a dolphin.

"There's one more thing I like about eating them," the dolphin chittered. She was quite close now. "It's...fun when they wiggle."

She was close enough to touch now and the otter reached a webbed paw out to feel the long bulge of shark, careful not to scratch her with his claws. At once she thrust herself against his paw. He could see the lower openings of her body now, the anus, the two slits where baby dolphins nursed, the genital slit, surrounded by flushed pink skin.

By the time the shark thrashed again his forepaws were around her, pulling her close. The slither of her smooth-skinned lower body against his belly was enough to make him unsheathe with a flick of her tail she slammed herself against him, enthusiastically impaling herself.

"How long can you hold your breath ottooooooh," she groaned, for just as he went to the hilt in her her meal thrashed and it was almost as though three of them were mating now. An otter, a dolphin and the shark that struggled for escape even as it made her move in strange and exciting ways. It made it harder to time his thrusts to match her movements. He didn't mind. He didn't like sharks much himself and the thought that it might know what was going on made it even better.

"Long enough," he said, for they had both just surfaced for a breath and he knew he could hold hit breath for eight or so minutes. Hopefully, he added silently.

In fact it was long enough, for the sinuous motion of a sleek dolphin thrusting back against him was like nothing he'd experienced. That and while he couldn't speak for all dolphins and all otters, this particular otter fit into this particular dolphin very snugly.

When he finally let out an underwater snarl and bucked in the water she matched his cry with a long chitter before dismounting with a flick of her tail. Even now she stayed close. He'd had a chance to grab her and start swallowing and hadn't.

Somehow the shark had lasted this long inside her but now it twitched one last time and was still. Her long beak curved in a grin, the shark's tailfins still poking out on either side. It'd be a few hours before she digested enough of her meal for those to disappear.

"See," she chittered, and hugged the long bulge of shark with her forward flippers. "It does make things fun."

The otter nodded. She went on. "What would happen if I did what the sea lion did? Ate humans," she chittered, "So you lost your hunting ground?"

"I hope you don't," the otter said honestly. "I'd hate to have to find a new place to hunt. Then I wouldn't get to talk to you."

The dolphin's long beak curved in as much of a smile as she could manage. Mostly you read a dolphin's mood by body language, not by expression or the cant of its whiskers like an otter.

"There's still a bulge," she said as she swam up against him belly to belly, and though the shark was still he found the presence of prey inside her exciting. By the time she pressed her slit against his sheath he was already hard.

"Next time," she chittered, swallowing and then disgorging his shaft with her sex simply by arching her flukes, "I want to try it with someone alive inside you."

"Deal," the otter purred, and his webby forepaws went around her so he could match her thrusts with his own.

A long while later - long enough for the tailfins of the slowly softening shark to finally slip into her mouth and disappear, and for both of them to develop a pleasant exhaustion - the otter returned to the rocky outcrop he called home. The sea lion didn't ask what he'd been doing when he returned to the rocky little island. He just watched the otter curl up in a nook in the rocks and instantly fall asleep.

He'd been joking before when he said he'd heard of otters trying to make hybrids with dolphins, but apparently the otter hadn't thought it a joke. And that was fine. Maybe you couldn't make otter-dolphins, but with the help of a friendly she-dolphin you could try. The sea lion was certain the otter would do just that, repeatedly and vigorously.

That sort of activity would have the otter hungry again soon, and while the sea lion was certain that dolphin was off the menu for the foreseeable future, there were other things in the ocean and on the beach to eat.

Humans, for instance. Why, the sight of the three of them playing together was sure to make them smile. More than one would want to leap in and join in the fun. More than one would find a maw waiting for them as they plunged toward the water.

The sea lion smiled. It wouldn't be the first time they took advantage of human naïveté. You could get a lot of good meals doing that, as long as you were careful. No human who ever saw him eat lived to tell the tale, and he was sure that whether they ended up inside a sea lion, an otter or a dolphin their silence was equally guaranteed.
