Mina is a gorgeous 5'1" college student with an athletic build who works part-time in a campus lab while studying biology. Her workdays are mostly spent taking care of mice and feeding them to the various predators the lab researches. She does this almost every day and has become pretty good at it since the other employees aren't exactly qualified. Mina likes her job, though, and gets paid well for it. On one particular day, her boss Mark stops by her desk and asks if she could take care of something special today. You see, the lab has an experiment ongoing with a massive frog named Gerald. Gerald is a huge bullfrog that is about two and a half feet tall and has been living off a diet of goats and other small mammals. Mark tells her that today they want to test if the frog is capable of eating larger prey, and they need her to help them test this.
 
Intrigued by the experiment, Mina considers his proposition. From her study of Gerald and other predators in the lab, she knows what his digestive system is capable of. Having already seen him down live goats, she wonders what else the giant frog could eat. She asks Mark what specifically he has in mind for today's experiment. Mark says he will explain more after lunch, but that he thinks she is perfect to help with the experiment. Before she can respond to this, Marks walks off, stating he is going to find food. With that, Mina heads out for lunch while thinking about Mark's words. As she eats, she can't help but wonder what exactly Mark meant earlier. She wonders if it would even be possible for Gerald to swallow something bigger than a goat.
 
As the lunch hour ends, Mina returns to the lab, where Mark and another researcher are setting up equipment in preparation for the afternoon's experiment. As she enters the room, Mark approaches her and smiles as he says, "Hi there, beautiful; let me tell you what I have planned for later."
 
"Oh, uh, ok Mark," Mina replies somewhat nervously.
 
Mark explains that Gerald seems to be outgrowing his diet of goats, and they want to test his ability to eat larger live food, but in order to do so, they need to feed him something that won't fight back and risk hurting their precious frog. As he talks, Mina notices a 'distinctive' bulge in Mark's pants. He continues, "This is where you come in, my little buttercup. Today we're going to test Gerald's appetite by feeding him something that will fill him up for days. We need someone to volunteer to feed him willingly so that we can study his ingestion and digestion of large live prey without risking him getting hurt. As the smallest person in the lab, you have been chosen for this important role."
 
She swallows hard and realizes that he meant just what he said. "I'm not sure, Mark. How will you get me out once you have your data?" She asks nervously.
 
Mark shakes his head and chuckles. "Mina, my dear, this is a one-way trip. In order to get the data, we need to study the entire process, from ingestion to disposal."
 
Mina's heart stops as her worst fears are confirmed. She looks down at the floor with fear as he says, "You see, sweetheart, when Gerald swallows you down, you'll get to experience firsthand something nobody has ever experienced before. As frogs breathe, air circulates down to the stomach, so you won't suffocate and will get to experience the stomach slowly breaking your body down over the course of two weeks. Our best estimation is that you'll remain conscious for at least the first week before your body is broken down enough that you lose consciousness."
 
Mina looks up at Mark wide-eyed with terror, not sure whether to cry or vomit. A cold sweat breaks out on her face, and her knees go weak. As Mark sees this, he steps forward and places his hands on her shoulders to calm her down. He looks deep into her eyes and says, "Don't worry, darling; we'll get through this together. Just relax and try to enjoy it; this is how scientific progress is made!" Mina considers Mark's words, thinking about how she always said she wanted to dedicate her life to science, even though she never thought about it in this way. This is her chance to change the world and make a name for herself. Without realizing it, she finds herself nodding her assent to his proposal.
 
Mark grins as he sees his words get through. He puts his arms around her waist and pulls her close as he kisses her. While returning Mark's kiss, Mina's mind is still a thousand miles away as she considers what she is agreeing to. Before she can think further, Mark pulls back and says, "We have a lot to prepare, but we should have everything ready soon to begin our experiment. We'll also need to get you ready with some sensors that will be used to study your digestion. Once that's done, we'll send you to Gerald and let nature take its course."
 
Mina nods her head numbly as Mark releases her and says, "We have a few things to discuss before we move forward, don't we, my dear?"
 
Mina simply nods her head again in response as Mark leads her to a conference room. Inside, Mark begins explaining the details of the upcoming procedure. They will be injecting Mina with sensors that will monitor her internal activity as she is fed to Gerald. Mark explains that these will give them invaluable information on the physiological effects of being swallowed by a supersized animal such as Gerald. Mina thinks about what this means, as she was recently considering a career in biochemistry, but she supposes that will no longer be happening.
 
After a while of Mark talking about the various sensors they would hook up to her, Mina asks him a question: "Why me, Mark? Why not a pig or some other large animal? If you don't want Gerald to get hurt by the creature fighting back, why not just sedate it?" Mark looks over at her and reiterates, "We need the meal to be alive and unaffected by drugs or anything else that would make it different than prey that Gerald might find in the wild; this means we need you."
 
Mina nods again and looks back down at the floor, her last hope dashed.
 
She tries to avoid looking at Mark as she admits, "But…but what about my studies? What about my future? Isn't there something we can do to get me out of here?"
 
Mark replies, "Unfortunately, there isn't; I already talked to the insurance company, and you're too valuable a specimen to risk losing. The fact that you volunteered yourself makes it much easier for us because we didn't need to get the permission of anyone involved to continue. So please, just try to enjoy it, Mina; maybe if we succeed, this experience will lead to advancements in science that can help many people someday."
 
"Speaking of insurance," he continues, "I need to have you fill out some paperwork consenting to what will happen to you over the next week."
 
He leads her back to the lab and instructs her to sit in a chair near the computer. He starts entering a series of commands to initiate the consent form. As the page comes up, Mina sees that the information entered so far indicates she is nineteen years old, five feet, one inch tall, weighs one hundred and fifteen pounds, and currently does not smoke or drink alcohol. She frowns slightly at the description, but she doesn't protest as she realizes this is necessary. She continues past the pre-filled information and enters her personal health history, exercise habits, as well as some personal questions about her sexual activity and libido. "I know this sounds like a lot of information, but all this is needed in order to keep track of your progress, plus what does privacy matter when you'll be digesting inside of a frog in a few hours?" Mark says as he pulls up a form for Mina to consent to giving up her human rights in order to become a meal for Gerald. "Once you sign this document, you are no longer legally a human being; you are the property of the lab for the purpose of this experiment; there is no turning back," he informs Mina.
 
When she reaches the end of the form, she takes a moment to read through the fine print, mostly legal jargon about releasing the lab from any liability for any injury or death sustained during the experimentation. When she's finished reading the document, she hesitates and then signs her name in the designated place on the bottom line. Mina can feel a lump forming in her throat as she hands the paper back to Mark, unsure of what to say. Her mind reels as she thinks about what has happened so far and the implications of signing this form.
 
Mark leans forward to hold Mina's hands reassuringly as he says, "Thank you for your willingness to help us advance the field of biology today. The research from this experiment will be groundbreaking and will allow me to finally be recognized for my genius."
 
Mina manages a weak smile and replies, "Thank you for letting me be part of this experiment; hopefully it won't be for nothing."
 
As Mina gets up to leave, Mark gently takes her by the arm and tells her to stay put. "Now that you're lab property, we are required to follow the same rules for you as with other biological specimens." Mina looks shocked at Mark's sudden change of attitude, but quickly realizes that it is for her own good. She is no longer a person; she is just a mobile pile of nutrients waiting for its purpose to fuel Gerald the frog.
 
Mark sees this realization cross over her face and smiles appreciatively. "I'm glad you understand. Now we just have a few more things to take care of before you can get acquainted with Gerald." He leads her out of the conference room and into a small medical examination room. "Food, I need you to remove all of your clothing and jewelry and place them in this disposal bin; you won't need them anymore," he instructs.
 
Mina is surprised; she hadn't considered that she wouldn't be able to preserve her modesty, although she reasoned that she wouldn't need clothes where she is going. "You can still call me Mina," she grumbles at Mark as she pulls her shirt over her head, revealing her shapely breasts and midsection.
 
Mark is distracted by staring at Mina while she removes her bra. "You aren't Mina anymore; you are simply the food for our test subject, Gerald. Soon you'll be converted into nutrients to fuel him. Please remove the rest of your clothes." Mina blushes as she unclasps her jeans and slides them down her legs. As she steps out of her pants, she's forced to remove her panties, feeling self-conscious as she shoves them in the disposal bin. "And your shoes—you don't need them anymore," Mark adds, watching her bare feet gingerly step out of her boots.
 
Now fully nude, Mina stands up and tries to cover herself with her hands. Mark looks her up and down, appreciating the curves of her young, well-toned body. After a moment, Mark looks back at Mina's nervous face and says, "I think I have an idea for how to relieve your stress before we get you hooked up and fed to Gerald," while approaching her.
 
He slowly caresses her hair and neck, massaging her scalp lightly as he moves his fingers down her chest. Mina resists at first but quickly submits, remembering her role as nothing more than property of the lab to be used however Mark desires.
 
Her resistance melts away as Mark's hands massage her breast and brush against her crotch, running his thumbs along her slit and pressing firmly against her clit. Mina is overwhelmed with pleasure and shame at the sensation as she realizes she is allowing a stranger to touch her intimately. "Let's forget the frog for a moment and just relax together; you look really stressed and confused right now," Mark encourages her.
 
Realizing this to be her last chance at sexual gratification before she is claimed by the hungry stomach, she gives in to Mark. Leaning backwards onto the examination table, her pussy dampens with arousal. Feeling her excitement rise, she unbuckles Mark's pants and removes the culprit of his bulging.
 
"You are an amazing specimen; in truth, I've wanted to fuck you since you first joined the lab." Positioning himself between her legs, he leans in and whispers, "I've also fantasized about watching your nude body disappear down Gerald's throat." As she is already wet with anticipation, Mark slides his throbbing member into Mina, eliciting a gasp.
 
Mark pushes himself deeper into Mina with each stroke, filling her hot cunt with every inch of himself as he works her body. Her moans become louder as she loses control. As Mina feels herself moving towards a powerful climax, she suddenly hears Mark groan, and she feels him filling her with his semen. "You were just as I expected, my dear frog food...exquisite," Mark says as he pulls out, leaving Mina unfulfilled on the brink of release.
 
Mina, surprised at the sudden emptiness, spreads her legs wide, pleading for more of Mark's attention as she begs him to finish what he started. Mark shakes his head as he pulls his pants up. "You need to get it in your head that you're just frog food now. All you exist for is to provide nutrients for Gerald. I was just using your body for myself." With his pants back on, Mark leaves to go retrieve the sensors that would track Mina's vitals through the ordeal.
 
Mark's words are cutting and remind Mina of the fact that she will never be anything more than a piece of meat. She sinks back onto the examination table, defeated, her desire unsatisfied, and her pussycat dripping with Mark's cum.
 
As she waits for Mark to return with the various medical equipment, Mina stares blankly at the ceiling, thinking about how just yesterday she was planning a date with a cute guy from her microbiology course. Now all that her future held was a slow and painful digestion in the stomach of a giant frog.
 
Mark returns quickly, wheeling a cart with three injection needles, interrupting her pondering, "Alright, frog food, I need to inject these sensors into you, and then we can get you off to your date with Gerald." Mina glares at him before numbly accepting the shots.
 
Mark narrates, "This will monitor your basic vital signs like heart rate and blood oxygen content," followed by an injection into her left arm. "This one will track your organ functions; we'll be able to watch in real time as your organs stop working." This shot is big and is injected directly into her chest. "Lastly, this one will allow us to hear you throughout your digestion." The small needle is nothing after the previous one, and it is injected into her neck.
 
"That should do it; we'll confirm that the monitors are working, and then we're all set to go ahead with the experiment!"
 
As Mark goes to step out of the room, Mina calls out one more question: "What will happen to me once the experiment is over?"
 
Mark pauses. "The full digestion process should take about two weeks, but, as we told you, we only predict you will survive for about the first week. We expect Gerald to be able to process 95% of your mass and convert it into useful nutrients. The remaining 5% will be excreted in the typical manner and will be used to fertilize some of our young carnivorous plants, helping them grow until they're big enough for us to experiment with feeding them other pretty specimens like yourself."
 
Mark heads out of the room without replying further. Mina starts shaking uncontrollably at the thought of having her insides digested, imagining being torn apart by stomach acid and enzymes. She squeezes her eyes shut, trying to block the images from her mind, wishing it was all a bad dream.
 
A couple minutes pass before Mina hears a knock on the door. "Come in," she mumbles softly as she attempts to compose herself. Mark leans into the room and says, "It's time; follow me to Gerald's enclosure."
 
Mina stands unsteadily and walks to join Mark at the door of the examination room. Stepping out into the hallway, she once again feels exposed in her nudity and stops for a moment. A slap on the ass quickly breaks her pause. "Come on, everyone is waiting; this is no time for modesty," Mark chastises.
 
As they walk through the halls of the facility, everyone's eyes are on Mina; she even notices some of the other college students that she works with staring at her nude form.
 
Her paranoia rises as she thinks that everyone in the building must know she's about to be eaten by a supersized frog. Finally, they reach an unremarkable set of doors with the label "Giant Frog Enclosure," and Mina feels a shiver run through her body. This was it.
 
"This is where we separate; you'll go inside, and I'll head over to the observation room to monitor your ingestion. Thank you again for your sacrifice in the name of science," Mark states calmly.
 
"Please don't worry; if you behave and make it easy on Gerald, he should treat you even better than his normal live meals. Please try not to fight or resist," he says while offering a reassuring smile. "In order to fit your whole body in his mouth, you'll need to curl up and remain in that position until he has swallowed you and you are safely, at least for him, deposited into his stomach. Do you have any final questions?"
 
Mina shakes her head, resigned to her fate. "Good luck and good bye," Mark says as he gently pushes open the doors to the room and motions for Mina to enter. As Mina walks into the room, she glances around nervously and feels her heart flutter as she sees a small army of scientists and technicians watching her from a large window in what she can only assume is the observation room. The room itself is relatively empty, aside from a small pond, a warming rock, and, of course, the giant frog lounging on the rock.
 
Gerald is oversized but only comes up to Mina's waist in height. What he lacks in height, he makes up for with his enormous mouth. He regards Mina curiously as she approaches. Humans normally bring him food, but this one doesn't appear to have anything with her. His stomach rumbles as he smells her scent, unobscured by the protective suits the researchers normally wear into the habitat.
 
Mina hears the stomach rumble and flinches at the reminder of her final destination. She continues approaching slowly to show the frog that she isn't a threat, and when she is about five feet away from his maw, she turns around and kneels down.
 
The frog watches curiously as she leans forward, presenting her ass and exposed slit to him. Her face burns with embarrassment, knowing that all of the researchers are currently getting an excellent view of her most private areas from the multitude of cameras positioned around the room, recording her final moments outside of the creature.
 
With her ass fully presented to the amphibian, Mina curls her legs tightly to her chest, arching her back to press her breasts against her knees. This position of complete submission to the creature that would destroy her leaves her with a mix of fear, anticipation, and, surprisingly, arousal?
 
Drawn in by the sweet scent coming from her moistening lips, this is all the indication Gerald needs to understand that this human is his meal. With lightning speed, his sticky tongue darts from his mouth and impales Mina's excited sex. Before she has time to even process this violation, the tongue retracts while maintaining its hold on her pussy, pulling her feet and rear into the drooling maw.
 
His tongue thrusts deep into her as she squirms under his assault; his teeth are dull and only serve to hold her body in place as his tongue explores the tasty well of flavor that it has found.
 
A flood of pleasure explodes inside Mina, drowning out all rational thought. Instinctively, she arches her back further, causing her tits to bounce obscenely as the giant beast relentlessly works her pussy. Every sensation she experiences overwhelms her as her body becomes consumed with orgasmic bliss.
 
Every instinct in her screams to fight back and escape the clutches of this beast, but Mira resists and does her best to hold still and allow the amphibian to have its way with her. In the observation room, Mark grins as he watches the display before him, reminded of what the walls of Mira's sweet snatch felt like around his cock.
 
The combination of her pent-up sexuality from Mark's betrayal and the overwhelming experience of being half-eaten by a giant frog caused Mina to lose control, and she cries out loudly as an incredible climax overtakes her. As the waves subside, Mina finds herself floating in a sea of bliss, a warm tranquility overcoming her body as her core continues convulsing and orgasming from the onslaught of pleasure she is experiencing.
 
As her pleasurable high subsides, Mina discovers that the frog has removed its tongue and uses her motion to move her further towards the entrance of his throat. Now, only her head and breasts remained outside Gerald's slimy lips. She glances up at the observation room and catches one last glimpse of Mark staring with fascination at her consumption before, with a large slurp, the frog pulls her rear into his throat and the lips close in front of her face, shutting her off from the outside world for the last time.
 
Realizing that her time has come, Mira doesn't fight as the frog pulls her deeper into its throat, which quickly opens into a large cavity. As her head is squeezed into the throat, she leaves behind any hope of amounting to anything more than food for this monster. The rest of her body slides into the cavity, which could only be one thing—her new home: the stomach.
 
The walls of the stomach are thick and covered in folds, visible from the slight bit of light making its way through the skin of the frog. A puddle of unknown fluid pools at the bottom, mixed with the orgasmic juices still leaking from her overstimulated pussy. A repulsive smell of stale, acidic air mixed with that of rotting meat fills her nostrils. With a sickening feeling in the pit of her own stomach, Mina realizes that this disgusting sac will be all that she'll ever know for the rest of her short life.
 
At this point, Gerald had settled back down on his warming rock, ready to rest while his body processed the huge meal he had just consumed. The observation room erupts in cheers and applause as the riskiest phase of the experiment is completed without a hitch. Monitors show Mina's vitals are heightened by the stress of the situation but still at sustainable levels.
 
Back inside the stomach, Mina lays in a void. She gazes at the stomach walls, contemplating the events that led to this moment. Thoughts of betrayal, humiliation, and sadness plague her as she desperately tries to accept that this is how she will spend the remainder of her existence. She feels her captor settle, and from inside she can hear his breathing slow. She realizes that the frog is falling asleep. With the exhaustion of being eaten and everything that led up to it, the slowing body around her lulls Mina into rest.
 
Some time later, Mina awakens. Forgetting what had just happened, she is confused as her compressed body is massaged from every angle by the hot and slimy walls of the stomach. She is completely drenched in fluid, and her lower legs, still beneath her in the uncomfortable curled-up position, are partially submerged in the fluid that is higher than when she entered the organ. After a moment of panic, she remembers the events from the previous day, which then leads to despair as she is reminded that all she has to look forward to now is a slow and painful digestion in the stomach of this frog.
 
Suddenly, she feels herself caressed through the skin of the frog, and she hears a familiar voice. "Glad you got some rest in after that incredible performance!" Mark exclaims. "That was exquisite; we especially like how you used your ass to entice the frog into eating you."
 
"Please stop talking...please just let me die," Mina pleads weakly.
 
"Relax, you'll be dead soon enough," Mark says matter-of-factly. Mina continues to beg for mercy: "Please let me die alone; you've already taken so much from me; at least give me peace!"
 
"Remember, you still have about five or six days remaining before you lose consciousness. I just wanted to check in with you to see how the process is going," Mark replied, ignoring her pleas.
 
"I'm soaked and cramped and miserable, you piece of shit," she replies. "Is that enough information for your fucking report?" Mina is filled with rage and anger at this man who took everything from her. He convinced her not only to give up her future but also to die in the most humiliating and painful way imaginable.
 
Mark smirks, and his hand, pressing in from the outside, moves to grope her ass. Mina bucks, trying to push him away, but the confined space of the stomach makes her efforts fruitless. As she fights back, Mark comments, "Amusing choice of words; after all, you're the one in the process of becoming a piece of shit. Digestion has just been warming up, and you'll really start to feel it in a few hours." With that, Mark stood up and left the habitat, once more disconnecting Mina from the outside world.
 
As the hours pass, Mina comes to the surprising realization that one of the worst parts of this digestion is actually boredom. Her only release is bouts of masturbation, aided by the sensual feeling of the stomach's full-body massage and her complete submission to this animal.
 
In time with Mark's promise, the undulations of the stomach walls slowly become more intense as the digestive fluids are massaged into every part of Mina's body, now just nutrients to be processed. She begins to feel a tingling sensation across her exposed skin and inside her pussy as she inadvertently aids in spreading the fluids through her self-pleasure. By now, the acids had completely covered her scrunched legs, while her breasts and exposed pussy were partially submerged.
 
This tingling grew painful and was accompanied by an intense itching. As she scratched at her itchy skin, patches began to come off and join the digestive slurry assaulting her body. By this point, she had no idea how long it had been since she knelt before the giant frog, and the pain of her dissolving body made her yearn for the release of death.
 
Even if she did manage to resist the process, she knew that there was no way she could ever claw her way out of this torture chamber or escape the hungry grasp of the frog. Now, she knew it was only a matter of time before she died inside the belly of the frog.
 
Over the next several hours, the sensations increased until they were unbearable. Mina screamed at the top of her lungs as her whole body burned. It seemed impossible that this could continue for even another hour, but sure enough, hour after hour of agony passed. Time lost all meaning for Mina; she was losing her mind.
 
It was at this point, four days into her digestion, that Mark once again made his presence known. "How do you feel, my little experiment?" he asked.
 
Without even thinking, Mina rasped, "Fuck you."
 
"Why is that?" He asked, "You knew this would happen when you signed those forms. You knew that you were donating your toned, young body to science. Your research here involved feeding live mice to all sorts of predators. Why should we pity you any more than the mice?"
 
Mina replied with as much force as her failing body could muster: "I trusted you, and you convinced me that there was no other way for your research to continue without this sacrifice. You used me for your own pleasure and then sent me to die this terrible death."
 
The loud noise and movement from her outburst caused the stomach walls to begin to contract violently, tightening around her decaying flesh. The digestive fluids became more viscous as they coated her decaying skin. She didn't know how much longer she could take the discomfort. Even though she had agreed to do this, she never imagined that her death would involve such excruciating pain. She realized she had nothing left to lose, so she started to scream again, "Stop! Please, stop! Let me out, please!"
 
Mark shakes his head. "Dear, it is much too late for that; it would completely ruin all of our data from this experiment. Gerald has also used a lot of energy digesting you; removing the fuel he needs to replace it would almost certainly be fatal for him. I'm afraid you'll be in there until he's done with you."
 
Mina's pleas turn back into screams as the stomach continues to eat away at her body and Mark walks away.
 
Over the course of what felt like eternity, Mina's skin was completely dissolved, exposing the muscles underneath. It had been ages since she had the occasional distraction of sexual pleasure, and now her only company was the pain of her failing body. As the acids worked their way through her muscles and internal organs, the data from the sensors continued to update the observation room on her condition.
 
The one mercy that Mina received was that on the sixth day, her heart finally gave out and she was released to the restful arms of death. The scientists theorized that the reason she died earlier than expected was because Gerald was even more capable of consuming large prey than they anticipated.
 
The remainder of the experiment went by uneventfully as Mina was fully broken down into a nutrient slurry, which fueled a massive growth spurt for the frog. As Mark promised, the solid waste left over was used to fertilize young Venus flytraps, which were the lab's next supersizing experiment.
 
Standing in the control room after no trace remained of the bright young researcher whose name he had already forgotten, Mark spoke to a colleague, "With this success, we should get a whole new wave of funding for these experiments. Make sure to put up more posters advertising our lab as a great place for undergraduate research. I have a feeling we're going to need some new...talent."
