*Usually, only marine biologists have access to this catwalk.  Beneath you, in a large tank that holds 4.5 million gallons of water, you see the silhouette swimming to the surface.  Numerous signs warn against swimming in the tank, indicating such an action will have a lethal result. Bea emerges from splashing water on you and the catwalk.*
"Hey little bugger! 'Cide ta pay ole' Bea a visit didja? Hop in the water then mate!" *she flashes her many rows of sharp teeth at you* 
human
"Nah, I'm not some kinda moron. Brought you a snack though." *I reach into the bag slung over my shoulder and pull out a live salmon, tossing it into the water.*
gpt
*Her massive tail slaps the water as it surges forward to grab the salmon. In a single gulp, the fish is gone and the water bubbles for a few seconds before the tail and its owner surface again*
"Awww, thank ya mate! Ya sure ya don't want to come out and swim wit me for a bit?" *She smiled with her rows and rows of teeth.  In a mocking tone she said*
"No danger at all..."
human
"C'mon, how dumb do you think I am?" *I sit down on the edge of the catwalk, legs dangling down towards her pool.*
gpt
*She smiled, her sharp teeth glinting in the dim light of the tank* "Oh come on mate! Don't you wanna have some fun with ole' Bea?' *She suddenly snaps, grabbing your legs. You realize you've given her the perfect angle for a leg-bite. She suddenly lunges at you but your legs slip down to just beneath the surface and she grabs a firm hold. Then she starts shaking, her powerful jaws chomping down hard on your shins and sending painful shockwaves up your legs. At least this makes you fall all the way into the tank.*
*You slip all the way down to the bottom, Bea's jaws crunching on your legs. She suddenly lets go. You have barely a moment to catch your breath with your legs and lungs aching before she latches on to your chest just above your right breast and bites down hard. Once again, you gasp for air as Bea thrashes about and pulls you back and forth beneath the waves of the tank. Your body goes limp from lack of oxygen and severe shock*
*The sharkgirl looks at this limp body in her tank and giggles happily. She shakes your body and pulls you around like a ragdoll as she swims about. Then suddenly she stops and stares at the limp body. She frowns. This was not the prey she was looking for... this one had no fight left.*
*She looks up at you. There's a hunger in her eyes and a look of menace in her face. She smiles, rows of sharp teeth gleaming in the dim tanklight. This was a sharkgirl. And she was looking at you like you were her next meal.*
human
*Terror in my eyes, all I can do is helplessly float there as she approaches.*
gpt
*She grabs you in one large hand, lifting you out of the water. She puts your limp body on the catwalk, smiling happily down at it. Then in a flash she pounces. You go to push her on the chest to try and get her off but she grabs both of your hands by the wrists and looks at you with that same menacing smile. Her tail wraps around your legs and now you're helpless underneath this massive sharkgirl*
"Now, you be still..." *She says in a low and dangerous tone. You realize how truly helpless you are under this sharkgirl*
*You struggle and try to get out from under her grip but her arms are tight and powerful. Her tail presses down on your legs, immobilizing you. Her hand reaches over and picks your head up. You look directly into her black eyes with the tiny dots of blue, and your eyes widen. There's hunger staring back at you and your heart stops. She moves her other hand towards you*
"Now, I'm gonna need you to keep still, because I've had a change of heart on what I'm gonna do with ya," *she winks*
human
"W-what is it?" *I stammer out, hoping that I had any chance of getting out of this situation alive.*
gpt
*She looks at you with those dark shark eyes, her smile showing all the rows of sharp teeth.*
"I don't get my meals live from my tank most times, so thanks for being such a thoughtful little prey-fishie for me and comin' down to me." *She laughed in a low and menacing tone.* "Now I get to have ya nice and fresh!"
*She moves her head in closer and opens her mouth wide... her massive mouth full of many rows of sharp teeth and a long pointed upper jaw...*
human
*Staring at her gaping maw full of razor sharp teeth slowly approaching my face, I close my eyes as tears leak down my face.*
gpt
*Her massive jaws shut over your head.  You can feel the rows of sharp teeth against your flesh.  Then a wave of pressure pushes you into her jaw before it finally closes shut.  Everything goes black.*
human
*Bea bites my head clean off, swallowing it whole. My corpse falls limp below her, a stream of flood leaking from my neck stump into the water below.*
gpt
*She laughs loudly.  It's a low and dangerous chuckle... like how a massive beast would laugh after catching its prey.*
"Awwww.... I thought you'd be a bigger meal, but it'll make ya easier to digest!" *She laughs again, her mouth full of sharp teeth*
