=== A whale of a time ===
 
Marina was a whale girl, not a real whale, but a monster girl with some special features characteristic of a baleen whale: she had incredibly wide cheeks, in which she could hold more than her own weight, and she could eat incredible amounts. The two things she couldn't do with the baleen she had instead of teeth and the narrow maw of a filter feeder was chewing and, unlike other pred species, swallowing large prey in one piece.
 
So, she was the target of ridicule at her school, and even though she was strong and could easily shove the other students who bullied her into her mouth, the final step of silencing them once and for all by forcing them down her narrow gullet and thus drowning her troubles in stomach acid was denied to her. On the contrary, the worst bullies just went for it, and for newcomers to the school it became a test of courage, a rite of passage, to tease her until she grabbed them, and bets were placed on how long she would keep them in her cheeks this time.
 
This continued until her senior year, and only one student, who had moved in the year earlier, had not yet made the acquaintance of her oral cavity. Dustin, as he was called, was a reserved human boy, nice and friendly to everyone, including Marina. Over time, Marina even developed a crush on him, but he didn't notice. He obviously had a penchant for the 'real preds', who could devour prey as big as themselves like the frog, monitor or snake girls. But these in turn were not interested in him.
 
So Marina secretly began practicing her predatory skills in the hope of winning him over. At first, she could only swallow sardines, but gradually, over the course of months of practice, she managed to do so with herring, trout, mackerel, cod and so on, until, to her great pride, she was able to fill her stomach with whole, fully-grown catfish, tuna and sturgeon. The voluptuousness that resulted from these exercises silenced the mockery of all the male and even most female students, yet aroused the envy and fueled the resentment of her worst bullies.
 
The frog girls from the synchronized swimming team in particular, who had always had a certain rivalry with the freestyle swimming team, in which Marina was the most valuable member, still targeted her. But now, at the annual sports competitions between the neighboring schools, held this year at her school just before graduation, she saw a chance to show off her skills while getting revenge for years of teasing.
 
The freestyle swimming competition turned out to be somewhat disappointing, with her team just coming in third place, as Marina had lost quite a bit of her streamlined form. But now came what she had been waiting for. In lockstep to the rhythm of their opening music, the eight girls from the synchronized swimming team marched to the edge of the pool, forming an absolutely symmetrical figure until they jumped into the pool, and the music changed to Nelly Furtado's 'Maneater'. In absolute unison with the music, they performed their choreography, did their lifting figures, stretched their thick jumping legs with their webbed feet out of the water, creating a spume through which nobody noticed how Marina, who had secretly submerged at the far corner of the pool, went floating below the group along the bottom. There she waited for the highlight of the performance, the pyramid, in which the bottom four lifted three others completely out of the water, with the last of them standing on their shoulders.
 
This was Marina's moment. She pushed herself off the bottom of the pool and just before she reached the vigorously pedaling calves of the four base swimmers, she opened her mouth as wide as she could. Her cheeks expanded wide to accommodate the massive amount of water around the girls. As the frog girls' feet touched Marina's huge tongue, and the corners of her mouth rose around them like a wall above the surface of the water, the pyramid collapsed, the remaining four fell into the small pool formed by Marina's mouth and disappeared behind the closing curtain of baleen, over which her lips finally slid. While Marina floated on the water with her back down, the roar of the spectators, who had just cheered at the perfect lifting figure, ceased. It would have been completely silent if the music had not continued. She let the huge masses of water she had taken in with the swarm run off through her baleen. Sometimes a few fingers could be seen sticking out between her lips, trying in vain to work their way through the shaggy tufts of fiber - sometimes an entire arm had made it to freedom, only to be pulled back in again when Marina's tongue seized the associated body and forced it down her gullet. Clearly visible to the entire audience as bulges wandering down her throat, one frog girl after another disappeared into her forestomach in sync with the music. When they could be recognized as nothing more than sixteen pulsating bumps that their powerful legs formed in their struggle to free themselves from Marina's massively bloated stomach, Marina herself began to move to the beat of the music and, despite her huge, unshapely belly, finished the routine in her own way with astonishing gracefulness and elegance.
 
When the music stopped, there was absolute silence for a few seconds, until the crowd leapt to their feet and gave her thunderous standing ovations. Marina tried as best she could to bow in the water, and finally threw Dustin a kiss. He just stood there with his mouth open, clapping his hands slowly and absent-mindedly.
 
Marina had to use all her strength to heave her now almost tenfold weight out of the pool and concentrated fully on her balance so as not to fall over because of the approximately one meter tall paunch filled with wriggling frog legs that she was carrying in front of her out of her burst swimsuit. Dustin came up to her, still applauding.
 
"Wow, that was awesome! Great choreography! I didn't even know you were capable of that! But I don't want to stop you to get them back out again, after all, you don't want to digest them," he said with a grin.
 
Marina paused a little. She hadn't really considered this option before. "Yeah, sure," she said, "unless you want me to, of course," she added with a wink in a seductive tone.
 
Dustin was surprised for a moment, and what then appeared on his face could only be described as a duel between moral sense and horniness.
 
"Just kidding!" said Marina, who realized that, even though it would satisfy Dustin's desires, it would in the end burden his conscience. She gave him a big peck on the cheek and waddled swaying towards the shower rooms. "Well, you toads got lucky this time!" she muttered quietly as she went.
