I was hungry, so of course, I got myself some dolphins and then after, a nice young female megalodon that I tracked since a few days. All those aquatic creatures are very filling for sure.

My great friend  Fischie writed it for me after I presented him the picture, thank you a lot! Don't hesitate to comment on his page, he loves it! Here is the story as well.

A fatal misjudgement
(Soft vore, implicit and explicit digestion)
A young megalodon was cruising along at idle speed, enjoying the peace and calm of the deep ocean which he habitually ruled. She had been stalking a pod of dolphins over the last month, seeing to their numbers steadily dwindling while her belly was kept busy and her body growing slowly, so she could one day become the unquestioned master of the her watery domain. At her current size she was comfortably able to devour one dolphin whole and maybe cram half of or a small second one into her ever greedy stomach too.
One day the shark heard loud rushing and hectic squeaks coming from the direction of the pod which she tended to follow just outside visual range. Her first thought was that the dolphins had come across a baitball and were now feasting themselves on some hapless fish. This would be just fine for the shark as she loved to devour them well fed and nutritious. But after some time, things became more and more silent. The squeaks became fewer and fewer, replaced by loud gulps while the rushing prevailed. Alarmed, that something was probably stealing her mammalian buffet, she sped up and tried to confront the supposed intruder to drive them away and assert her dominance. Those were her dolphins and hers to eat after all.

She kept accelerating until she reached attack speed, prepared to surprise her opponent and rip a big chunk out of them, whatever they were. As the megalodon approached there seemed indeed to be a baitball involved, given the enormous shadow she saw straight ahead. Confidently she carried on and expected to find a few smaller, well fed scoundrels on the other side of it. But to her utter terror, she found the shadow belonging to a single creature, a scales beast of mountainous proportions. It was all grey had wings and a tail similar to a sting ray but also feet like some of the reptilians she sometimes snatched up in coastal waters.
But the most important thing was the one she could do nothing about at her current speed: The gaping jaws which seemed to have only waited for her arrival. A long tongue was rolled out to her like a red carpet, leading down into a dark abyss of a gullet, the route her pod of dolphins had likely taken a few minutes ago. Unable to brake or steer clear of the danger she soon found herself to the engulfed to the pectoral fins in the horrendous cavern, feeling long conical teeth poke at her thick hide as her eyes, well adapted to the dark of the deep, tortured her mind with a clear picture of the eagerly pulsating entrance to the throat which would ultimately devour her if she could not help it.
She could not.
The teeth, while not sharp enough to harm her, were still capable of holding her still as a hot tongue slithered over her underside, obviously covering her in some sort of slick slime as well as gathering her taste. She was an apex predator, or at least she was destined to become one before her misjudgement had landed her stuck in a greedy dragon’s maw. Instinctively she started to kick and struggle, the motions of her muscular tail only loosening the grip of her captor and helping him to propel his meal where he wanted it. The dragon seemed to support this accidentally helpful reflex of his prey by giving a strong swallow. The tongue rubbed up against the shark firmly, her rough skin now working against her as it provided the grip necessary to drag her into the slimy confines of the dragon’s throat which seemed to jump at her head and suddenly plunging her into utter darkness. At least now she did not have to see what was ahead of her, but the fleeting smell of digesting dolphins and the ever present rumbling and thunderous heartbeat of the monster which was in the middle of devouring her did not make things better.
She felt how her pectoral fins were uselessly pressed snugly against her sides while the next lurch of the powerful throat caused her dorsal fin to yield to her predator’s maw and fold up as well. This hurt a bit but she was almost numb to that sensation as she was in utter panic. Each swallow a certain pattern repeated itself. The jaws parted, the gulled dragged on her apparently tasty body and the shark struggled in utter terror only to notice she was only making things worse for herself. Then she always went still in mortified fear for the inevitable end of her journey only for the next swallow to drive her terror to new peaks.
The vicious cycle repeated itself over a dozen times before the dragon’s hot gullet hat to expand a last time when it widened from the thinnest part of the young megalodon’s tail over her impressive caudal fin. With a long squelching noise, the greedy gullet closed after the last, faintly twitching bit of prey before a final gulp seemed to echo through the ocean. The meal was concluded and a tremendous bulge lid down the long scales neck only to vanish in the huge predator’s chest.

Together with a good deal of water, the outclassed former predator slid down the long esophagus of the incredible beast which had tricked her. She did not know that the dragon had observed her following and hunting the dolphins for days, scheming and preparing just for this to happen. What she did experience firsthand though was what all those dolphins she had consumed must have felt like. Frantically struggling she was pressed against a tight muscular ring only for increasing pressure to build up around her rear until the sphincter yielded and her torpedo shaped body slid into a hellish chamber full of what she had considered her food supply for the next month. Faintly struggling dolphins were sizzling in a bath of hot acids inside the drooping cauldron of the great dragon’s stomach, now joined by a terrified megalodon which bit and thrashed at everything she touched. While unable to get a grip at the slime covered folds of the stomach, she did end up helping the huge beast in digesting his feast, herself included, by shredding and mixing up half of the other stomach contents.
Eventually though, she would succumb to the lack of oxygen, her gills and eyes burning painfully in the acidic environment as her struggled slowed to a stop. The last thing she noticed was a tremor all round as the content predator patted his overstuffed belly which, would he have been on land, would drag over the ground by now. The huge creature made a rumbling sound, seemingly approving of his meal and then all went silent to the shark.
