Man into Female Shark Transformation Story | Unwilling | NSFW | 3rd PoV | Very Painful | Anatomically Accurate | Body Horror

Ryan lived a healthy and stereotypical city life. He was unlucky enough to be chosen to become a test subject by a secret international corporation producing bio-weapons. He tried to fend them off, run away, but nothing he did helped his case – It was too late for him and he was at the mercy of specialised armed forces of the aforementioned corporation.

After quick apprehension they have tranquilised the unfortunate man. The corporation had professional procedures for transporting new test subjects into their secluded headquarters. Ryan was passed out for multiple hours as he was transported to the secret marine base in the middle of Atlantic by his captors. They took him to a huge chamber with a prominent hatch in the floor.

As was planned the subject was starting to wake up just to realise that he was stripped naked. He felt immediate coldness of the room after regaining consciousness . Ryan shook his head and slowly got up, still being dizzy and seeing everything in a slightly blurred way. “Wha- Where am I…? And why am I naked?! Oh God… Let me out!” – Ryan pleaded quickly realising the direness of his situation despite having no idea why specifically he was found in a situation like this. Nobody answered his calls.

The room he was in was almost completely empty – No humans in sight, just strange apparatus near the metal walls. Ryan looked around looking for a way out, but even if there was one it was certainly locked judging by the closed metal gates. Ryan didn’t care, he didn’t deserve to rot in some deranged looking cell and so he ran up to the closed gates and started pounding on them.

The second he reached them he was caught off guard by a sting in his thigh. “Augh! What the… Shit!” – He exclaimed in pain and shock when he noticed a dart with some kind of injector in it which just pumped some kind of green serum into his bloodstream. “T-This is just a nightmare… What was I even injected with?!” - Ryan freaked out and grabbed the injector dart before pulling it out forcefully. Some blood gushed out from the wound making him groan in pain, but then something unbelievable happened.

Ryan threw the empty injector away and stared at his thigh wound which started rapidly healing – His flesh knitted together until the pain and the wound completely vanished. Ryan was left speechless – Too many bizarre scenes appeared at once since he came to. He was about to start banging at the door again, but then he noticed something more strange happening to him.

He stared at his healed thigh and watched as it started changing hue. The discoloration was spreading over his leg, then the rest of his body. He felt skin all over his body start to itch as it changed. Its texture became coarser as miniscule hard scales grew all over his body. He touched his new hide with a trembling hand and realised that he never felt something similar in his life. Maybe once when he was fishing back in the day and caught a huge carp – Its scaly hide was somewhat similar to what became of Ryan’s skin.

Ryan stared at his body in disbelief. The scaly hide that covered him turned grey on his back and his underside was covered in smoother white scales. Ryan didn’t have time to panic as he felt more itchiness in several spots on his body. The hair from his armpits, groin, chest and even scalp started to fall out in sizeable clumps. “What… Is happening to me?! Whoever you are who abducted me, stop this nonsense! I’m innocent!” – Ryan yelled in horror as he plucked the remaining hair from his body. As he looked around with hair in his hands he realised that there were at least 10 cameras at the ceiling facing him to his horror.

He realised that whoever captured him wasn’t a compassionate person. A lot of bizarre feelings washed over Ryan’s entire body as his human features started to distort. Ryan frantically inspected his body as it started reshaping more drastically. His fingertips and toes ached. The second he glanced at them he realised why – His fingernails were dissolving and getting absorbed by his digits. Worryingly all of his limbs altogether started to ache and weaken gradually with each second. Although the worst pain was coming from Ryan’s spine.

“Hnnnnnghh-ahhhh…! Stooop itttt-ahhhhh!” – He roared in pain as he felt his spine start to elongate stretching his torso in inhuman manner. The spine was getting too long for his body and his rear was put under unbelievable amount of pressure. Until with a few wet pops his tailbone extended significantly and stretched the flesh above his ass making Ryan bend over in agony. “A tail… I can f-feel it grow. Oh God, oh G-hhhhaahh…!” – Ryan groaned as he felt and heard his tail extend further.

Ryan rested his hands on his knees standing in a bent over position. He felt that his thickening tail and altering spine disallowed him to straighten up and stand like a human. His tail slowly grew longer and the difference between Ryan’s hips and thickening tail was slowly disappearing. Ryan panted hard, despite feeling heated up he realised that he wasn’t able to sweat anymore because of his altered hide.

In between the changes new uncomfortable sensations started invading his head. Ryan immediately clutched his head and was terrified of how different it felt – It was all scaly and rough, completely bald as well. And what’s worse his hands felt how his ears started to retract into his head. He felt his earlobes wither into nothingness leaving smooth surface at the sides of his head to his dread.

Unluckily his head wasn’t done shifting in the slightest. Ryan gasped in deaf agony when he felt his head tilt upwards into a more feral and aquatic alignment. His neck started thickening, fattening up in grotesque manner until there was no distinction where Ryan’s head ended and neck began. Then came the skull changes. Immense pressure started to squeeze Ryan’s head from many angles into a more conical shape. The bones on his face were smoothened and simplified and some started pushing forwards.

“Ghrrrrraaaaaahnh! Shtrrrrroghp…!” – Ryan roared in guttural voice as his nose face started sharpening into a shark’s snout. His nose was pressed into a smoother, sharper and conical shape. His nose was gone, only two slitted nostrils were left on his snout. They slightly altered in purpose and would be used for smelling out prey now instead of just breathing. This was just one of the major respiratory tract changes that were in store for Ryan. He was forced to breathe through his widening maw now as his face continued to push out into a shark’s muzzle.

He felt his puny human teeth start to loosen up in his expanding maw. He spat them all out in one go, utterly disgusted at the realisation that he was becoming a common animal – A shark. He wasn’t able to move his head anymore, his limbs felt incredibly fatigued and started to shrink and get reabsorbed into his body gradually. This along with Ryan’s increasing weight forced him to finally fall down onto his smooth scaly stomach with a loud thud.

In the meantime his empty gums started throbbing violently as many serrated teeth started piercing them. Deadly, sharp triangles writhed their way out of his gums and slowly filled his humongous maw. The last huge fangs grew out of his gums and filled his maw to its extents. Ryan’s eyes changed from blue to black as the pupils expanded and his eyes were forced to spread apart and move to the sides of his head. With that his head was completely that of a great white shark.

Ryan was speechless, literally because his vocal chords have melted down into nothingness. He wanted to scream, not just out of pain, but out of misery – He was becoming a limbless predator of the ocean by the obvious signs of it. He was entirely ruined and he felt like it too as his hands started sliding off his huge head. His entire arms were shrinking and remolding into something more adequate for aquatic life. Worse fate befallen his legs which shrank at a more rapid pace and they were on a good way to completely disappear soon.

The tugging of his spine and tail signalled the continued growth of his tail. Ryan wasn’t able to look back as his tail thickened with necessary muscles and lengthened into its final impressive size. Ryan felt the tip of his tail start to morph. It started extending upwards and downwards forming a strong, but thin caudal fin at the end of his tail. Ryan thrashed his tail sideways as he felt it malform further as more fins formed before the caudal one.

Ryan felt a strange sensation of drying up. He was already mostly a shark and his hide was showing first symptoms of dehydration, luckily his respiratory system and gills were yet to fully form. Ryan flopped on the ground feeling his pathetic, small limbs retract into his torpedo shaped torso. He felt his limbs’ bones dissolve, flesh redistributed elsewhere. Ryan hissed in pain as his legs got fully absorbed into the area underneath his long tail.

His arms were spared that fate and instead underwent considerable changes as they started turning into pectoral fins. Ryan’s fingers were long gone, fused together. Hands stumpy and immobile on his shrinking arms. His arms started to flatten and bend backwards slightly. They slowly turned into resilient pectoral fins fully and were left without the ability to move which further mortified Ryan.

He flopped on the ground swaying his powerful tail to the sides uselessly. He just wanted this torture to end. Instead a sensation of pressure formed on his back. He felt like his spine was extending at one spot forming something flat. He quickly realised that it was his huge dorsal fin takin shape and slowly growing out of his back. It pulsated and slowly stood up erect atop on his back when it gained its final shape.

Ryan panted hard, which felt bizarre to do with his enormous maw. He had no other option than to endure the changes at this point, maybe he’d even be able to take revenge on his captors afterwards. For now he felt second, smaller dorsal fin form behind the first one. His torso felt like taffy as it was expanding in all directions, but most of all it grew in length while gaining that iconic torpedo-like body shape. Ryan’s bones felt weird to say the least as they degraded into simpler aquatic counterparts. A lot of his previous torso bones just disintegrated, since they were unneeded for his new species.

As if his situation wasn’t bad already he felt nauseating sensations all over his body as his organs morphed into simpler shapes. He was ceasing to be an omnivorous mammal and slowly becoming a carnivorous fish so his digestive track had some shifting to do. The strangest sensations came from underneath Ryan’s tail when he felt two new fins form – pelvic and anal one.

That second one ironically foreshadowed what was about to happen. Ryan wasn’t even able to express his discomfort with his face, since he lacked it at this point. He felt churning in his abdomen and his anus started moving closer towards his genitalia. His human cock and balls were already looking off as they started to reconfigure into something completely alien.

Ryan’s foreskin receded completely leaving a wet, red and shrinking shaft. His testicles got forcefully hauled deeper into his body where they underwent drastic changes into ovaries. His groin area was already scaly, but now it was becoming even less distinguishable from the rest of his body as Ryan’s cock became clit sized and got pulled into his forming genital slit with a wet shlurp.

Ryan would moan in forced pleasure if he’d be able to as he felt his masculine genitalia get inverted into a shark’s cunt nestled between his newly formed pelvic fins. The fins have spread a bit and his “cunt” throbbed in ecstasy as it collapsed with his anus. The two slits merged into one cloaca and with that the pleasure was slowly disappearing from Ryan’s body leaving him very horny and unable to stimulate himself further to his annoyment.

The lust slowly stopped clouding his mind and only then did Ryan realise that he wasn’t even a he anymore. He have read an article about shark long ago which said that the males had fin-like protrusions at the pelvic fin, while he felt that he lacked them. Ryan started jumping around from the realisation, surprising himself with the strength of his body. He slowly calmed down as he realised that there was one more change left and it wasn’t a pleasant one.

“Open the hatch and let the new shark into its enclosure. She will stay there for about a day and afterwards we’ll start the experiments. Most notably the consciousness test. We have no use for a mindless, primal animal. If we’d want that we’d steal one from a zoo. You see Ryan – If the experiment succeeded you just became the world’s first conscious shark. We’ll use you in reproduction or major international conflicts when needed. Better accept your new reality, resistance is futile…” – A mechanical voice resonated through the strange speakers at the ceiling.

Ryan had no intent of cooperation. He was a man, not some animal! – Conscious or not! As if as a punishment Ryan suddenly felt searing pain coming from where his neck used to be. Its sides started to split open into complex gills. Last minor changes occurred and with them Ryan became a grey shark completely. Struggling to breathe with his altered respiratory system he flopped around miserably. He felt like his respiratory system was on fire and he was about to pass out when he suddenly felt creaking and floor moving beneath his huge body.

Before he managed to pass our the floor beneath him opened up completely and made him fall into the water tank beneath it. Ryan opened his maw wide instinctively trying to scream, he was terrified he’d drown. He knew he became a shark, but it was a huge change in his anatomy – He had no idea how fast he’d get used to the water. He realised it almost immediately as he just floated in the water without suffocating. He moved his tail a few times and easily figured out how to swim. It was shocking how much his new anatomy guided him in his movements and helped him adapt to his new life. Still, he felt like what happened to him was utterly unjust and he wouldn’t just behave after being forcefully turned into a she-shark. One way or another he was forced to live in this body from now on and whether he’d finally cooperate with the scientists or just try and get his revenge was still uncertain…
