"We did it!" I clink my glass with my science partner I've been working with for several years. Today we finally finished the project we've been work8ng on, a revolutionary device that turns sea water it oxygen getting rid of the need for large limited oxygen tanks for divers and underwater vessels, on top of that the device can also work as a water purifier, allowing for drivers to stay underwater for much longer. We already have several companies interested and we're going to become rich.
"Get this down you." My partner hands me another drink.
"To being rich!" I down my drink.
I awake to the feeling of sea air blowing and spraying my body. I moan and try to open my heavy eyes as my foggy mind struggles to clear itself. As I blink and try to focus through the bright sunlight I see my partner looking down at me coldly.
"You're finally awake, I've been waiting a while." I go to ask him what is happening but my words arw muffled by what feel like a breathing mask sealed around my mouth and nose. I raise my hand to feel the mask only to look at it I shock, as I bring my hand up I see a blue green coloured webbed hand. Looking over the rest of my body my eyes widen in horror as I see a similar coloured mermaid tail running from my waist all the way past my feet and ending in a large pair of fins. I look to my partner and try to ask what the fuck is going on. All he does is look down at me in disgust and hatred.
"Partners, that's what we are? The thing about partners though is that they both contribute equally. The thing is I don't feel like your contribution was equal to mine, yet you were going to take half of the money. I did most of the work! You were my assistant at best, a rich guy who had a vague understanding of the science and funding my research." As I listen fear builds inside me as his years of pent up anger begins to flood out, I try to pull myself out of my mermaid tail but it won't budge and my webbed hands have hardly any grip to them. As I move I feel a large intruder stretching my ass open and a tube inside my cock, both linked to my tail.
"That tail isn't coming off. I used industrial adhesive and you won't be finding the solvent to dissolve it out here. Same with your new hands. You see I thought that I'd do one last experiment and test on the product, I wonder exactly how long it lasts. Then I thought that it would also be a great way for my partner to contribute." I roll slightly as the boat goes over a wave and I struggle to get back onto my front. My flailing like a fish out of water makes my partner smile in amusement.
"Time to start the experiment I think." I try to back away and slide my body along the floor with my hands but there's nowhere to go.
"You can probably feel our device resting on your back, that will provide you with all your oxygen and water. I also added a few sensors to monitor your life signs but don't get things wrong I'm not coming back for you, you'll be down there until you starve or get eaten. And just a word of warning if you get to near the surface the plug in your ass will give you one hell of a shock." I panic uselessly as he walks up to me and lifts me into the air, i try to figjt against him but he ignores my futile efforts. Bringing me to the edge I look down in horror at the large ocean below.
"Goodbye partner." At that he let's go and I plummet down into the waves below and sink down into the cold dark waters. As the salt water stings my eyes and fills my ears and also my ass revealing the plug to be somewhat hollow, I try to orient myself, my my hands and tail are surprisingly helpful in this. Looking up I see the silhouette of the boat above me and start to swim up kicking with my tail and pulling myself forward with my hands. A sudden painful shock erupts from deep within my ass and I flail wildly in the water like a fish caught on a hook, as I do I begin to sink down lower until the shocks cease. Breathing hard I try to recover, psyching myself up I swim up hard, as the first waves of shocks hit me I try to power through. As I get nearer and nearer to the boat the pain is overwhelming and my vision begins to blur, as I start to go faint and run out of energy, I watch the bottom of the boat get smaller as I sink back down into the depths, my tears of pain, anguish and terror lost in the ocean around me. Defeated I watch sadly from my watery prison as the boat moves away. As I continue to sink down the plug in my ass roars to life once more making me jump in fear, only instead of shocks these were vibrations, pleasant vibrations. I moan and wiggle as my cock pushes against my tail as I scream in ecstacy as the plug and adrenaline push me over the edge, my cum flowing into the ocean through a small hole in my tail.
Unable to reach the surface I begin to swim deeper causing my plug to continously vibrate and send waves of pleasure through my body as I explore my peaceful new home, seeing beautiful coral and fish swim by me.
Epilogue:
I moan as I'm brought to another orgasm, I exhaustedly continue to swim, my starving body screaming for food, part of me has even considered trying to catch one of the many fish swimming around me but I'd drown before I could eat them, that's assuming I can even get my mask off with my hands as they are.
I have no idea how long I've been down here under the waves, must be weeks, the moments of light and eerie inky darkness have blurred in a haze of orgasms, keeping an eye out for predators and endless swimming.
As I keep going I am suddenly brought to a stop. There's something in my way, a rope. I panic slightly as my arms get twisted and tangled in the netting, pulling on it in an attempt to free myself. Finally freeing myself I turn to see that in my panic I failed to notice the net closing around me and several other fish. As we start to rise, seeing the boat grow closer and larger I begin to panic and flail as fear overtakes me as I try desperately to escape the net. My fear is quickly proven correct as waves of painful shocks start to ripple continuously through my body causing it to twist and spasm in agony as I'm pulled up to the surface.
As I leave the water and feel the strange feeling of wind blowing against my flesh and the blinding light of the warm sun and the strange sounds as my ears empty of water, my vision goes dark as my body twitches and flops around on the floor of boat along with the other captured fish.
