Chapter 1 - Wrecked

It was a warm day. This close to the equator, it was always pretty warm, but today especially. Kat was sitting on the side of the boat, doing one final gear check before she dove in. She was an experienced diver, and her nimble hands darted from valve to valve, guided by muscle memory. Finally satisfied, she put her scuba mask in place and rolled backward off the side of the boat, into the warm Caribbean waters. 

The water was clear today, but there wasn’t much marine life to see. The tourists mostly clustered near the reefs, oohing and ahing at every sculpin and wrasse. She understood the appeal, but something about the vast sandy expanses of the open ocean felt more real to her. 

Still, it wasn’t just sand here. She’d come here looking for something specific, and she quickly spotted it: The wreck of an old sailing ship, the Calypso. It had gone down sometime in the mid 1800’s, and sat mostly undisturbed until it had been rediscovered a few years back. A few dive teams from the local university had done a quick survey for historical tidbits, but other than that few bothered coming out this far. It didn’t have a particularly interesting cargo. No gold, no slaves, no pirates, no civil war marauders. It was just carrying a shipment of sugar north to the Carolinas when it sank. 

The water was warm enough that she had no need for a wetsuit. She only wore her diving equipment and a yellow bikini. It didn’t have a particularly elaborate design, but still showed off plenty of skin. Simple, but flirty, just like she liked. The top was perhaps a little too small to contain her D cup sized breasts. She’d thought it was a good fit in the store, but now her soft skin bulged outwards a bit around the fabric triangles centered on her nipples. She made a mental note to fish around in her car to see if she’d kept the receipt. 

She swam languidly through the water, down to the bottom. The Calypso was perched slightly askew on a sandbar. Deftly, she slipped through a hole in the side and turned on her light to survey the interior of the ship. She drifted from cabin to cabin, letting her imagination run wild as she inspected the rotting remnants of each room. Had the captain stayed here? Was it on that table that he laid the course that would be his doom? She clung to the morbid hope that she might find some old bones, maybe even a skull or jawbone. 

A glint caught her eye. Some old piece of metal? Gold? It seemed unlikely the university surveys would have missed something so interesting, but perhaps the drifting sands had covered it during their visits. She reached out, brushing away some wooden debris, revealing a small blade underneath. She reached further, trying to brush away the detritus that was covering the hilt-

She saw a sudden flash of motion and jerked her hand back at the last moment. The moray eel that had made its home in a rotten barrel had lashed out at what it thought was prey encroaching on its lair. She scrambled backward, slamming into the hull of the ship. The moray snaked out if its lair towards her, and she scrambled backwards, trying to squeeze out an old porthole, fear surging through her veins. Eels bite deep, and if that thing sank its teeth into her she’d bleed out long before she could get help. At last she broke through, the rusty metal of the porthole leaving long scratches in her toned midriff.  

She was barely free when she heard a dull cracking sound and realized with horror that the commotion must have disturbed the old wreck. She turned her head just in time to see the mast slamming down towards her. She kicked, trying to get clear-

For a few moments she couldn’t see anything; everything was a sandy haze. She felt a terrible aching soreness in her leg, and she tried to reach down towards it. It was then she realized she couldn’t move her right foot. Panicking, she reached down towards it, only for her hand to bump into the boat’s fallen mast. As the sand settled back down onto the ocean floor, she could see that it had pinned her ankle against the ocean floor. She was trapped. 

She quickly realized that wriggling free was not an option. She tried to push the mast away, but it was too slick for her to gain purchase. She reached for her diving knife, only to find it missing. Fuck. It must have come loose when she was wriggling through that porthole. Panic starting to rise in her throat, she checked her tank: 80% remaining. At least she had time. 

She examined her surroundings: there was nothing within reach that she could use as a tool to pry herself free. The old wreck was still there. And that damn eel was poking its head out the porthole, looking at her with a dumb toothy grin. When I get back to shore I’m having unagi for dinner she thought to herself, glowering at the beast through her diving mask. 

Again she tried to push the mast away, but her fingers couldn’t find purchase. It struck her that she might be better able to get a grip if there was something she could wrap around the mast. She quickly realized her only option: her bikini top. She undid the tie at the back of her neck and pulled it off, letting her breasts float free. Mentally congratulating herself for her ingenuity, she wrapped it around the old rotten wood and gripped it firmly in both hands. She had to twist herself awkwardly to reach both ends, but she gave it her all. She gave three successive tugs, each time feeling the mast shift a teensy bit more than the last. She tightened her grip and took a deep breath and jerked with all her might -- only for the bikini top to snap in two. Fuck. 

Still grinning asshole? She thought to herself, turning to look at where the eel had been. But the eel was gone. She didn’t have to wonder long before she realized what had spooked him. A shadow was moving quickly across the sand, and she looked upwards. It was a dolphin! Her mind went wild with possibilities. Maybe it knew she was in danger? Maybe it had come to rescue her! Maybe it was going to eat that damn eel!

She waved at the dolphin, trying to get its attention. She was struck by how large it seemed. She’d seen pictures, but she’d never seen one in person, and the pictures gave her a poor sense of its impressive size. It was easily twice as long as she was tall, and she marveled at how quickly and effortlessly it moved through the water. 

The beast swam right towards her and circled her curiously, clicking at her. She gestured towards the mast, hoping to communicate her predicament. It seemed to understand her at first, probing the mast with its nose, circling to approach the obstacle from different angles. But the beast seemed more interested in the tattered remnants of her bikini top. After tossing one of the bits around with its nose, it turned its attention to her, nosing along her leg and up her thigh. Goddammit, quit goofing around idiot. She was beginning to wonder if maybe she was wrong to pin her hopes on this dolphin. And if she didn’t get free soon…

As the dolphin circled overhead, she realized it wasn’t an it: it was a he. And he was packing a helluva package. She was mesmerized by the creature’s long pink cock snaking out of its sheath. Did they swim around like that all the time? Or was the creature… aroused? She felt a chill run down her spine. 

The dolphin returned to nosing along her legs and towards her ass. She tried to calm herself, even as the dolphins slick nose rubbed against her inner thigh, probing towards her most delicate parts. She clung to the belief that the dolphin was still going to save her somehow… right up until the moment it tore off her bikini bottoms. The dolphin’s sharp teeth shredded the fabric like paper, leaving thin trails of blood where the teeth sliced along her ass cheeks. She was frozen in shock, now completely naked and trapped beneath the lustful beast. Any hope she had that the dolphin might have had noble intentions were shredded along with her bikini. 

She felt the creature move over her, its smooth gray skin rubbing against her back. This can’t be happening, she thought to herself. The powerful creature eclipsed her, its long snout blocking her view ahead, its flippers settling above her shoulders. Panicking, she struggled in vain to try to get her leg free. She felt something long and hot settle on her lower back, and she instantly knew what it was. She twisted frantically, her exposed breasts scraping against the sand as she struggled. But it was futile. She could feel that tremendous heat start to move against the small of her back. Slowly at first, but with increasing desire. She could feel the dolphin moving around, trying to find her entrance. She bucked her hips furiously, trying to keep the dolphin from finding his mark. 

The creature bolted, furious that it’s would be mate was so resistant. It circled her, clicking and snapping at her. Her eyes were locked on the dolphin’s long pink cock. That’s the cock that’s going to rape me she thought. Something in her broke, and she realized she was never going to get free. She was going to drown here when her air ran out, and her last experience on this earth was going to be a brutal rape. Her pussy was going to be leaking dolphin cum as she took her last breath. 

Sensing the fighting spirit going out of his mate, the dolphin once again lined up over the diver’s toned body. Meekly Kat lifted her hips up: partly out of submission, partly out of fear the dolphin would take her ass if she kept fighting. She could feel the dolphin’s tapered cock tracing a line up her thigh, looking for the warmth of her pussy. At last it reached her labia, but the dolphin didn’t take her yet. It seemed to hover, the flickering tip of its tapered cock teasing her folds. It seemed to take a perverse pleasure in toying with its prey. She felt completely powerless, her body a plaything for this cruel beast. She cringed, fearing what came next…

With a powerful lunge, the dolphin penetrated her warm sex, its tapered cock filling her more deeply than she’d ever experienced. Her eyes went wide with shock, and she clawed at the sand in pain. She could feel the tip of the dolphin’s cock slam up against her cervix. She barely had time to orient herself before the horny creature pumped its dick into her pussy once more. She’d been with her share of men, but nothing prepared her for the sensation of the dolphin’s cock spreading her wide. It felt like it was going to split her in two. 

The dolphin found his rhythm, pumping his tapered cock into the tiny diver’s unwilling body. As the shock of the initial penetration wore off, she became aware of subtler details. The dolphin’s cock seemed slick, and penetrated her with ease. She’d messed around in the hot tub with an old boyfriend, but it had been deeply uncomfortable. The water dissolved her natural lubrication, leading to a lot of uncomfortable friction. That definitely wasn’t the case with the dolphin though; it had evolved to take a mate underwater, and the cock surged within her, sliding into her with perfect smoothness. The pain began to dissipate as well as her walls stretched to fit her rapists intruding cock. Her breasts bounced in the warm Caribbean waters in time to the dolphin’s thrusts, swaying like seaweed caught in the ocean current. She could feel her nipples hardening as well, the tips brushing against the seafloor as the beast took her. 

Despite herself, she began to shift her hips to meet the dolphin’s thrusts. Each thrust seemed to roll through her like an ocean wave breaking on the shore. She could feel the dolphin’s cock undulating within her, as though it were a living creature unto itself. She unconsciously moved a hand to her breast, stroking her tender nipple, beginning to lose herself to the sensation of being fucked. She felt a tension building in the dolphin, and she closed her eyes, anticipating the beast’s release. It came in a torrent. She felt as though she were going to burst from the sudden intense pressure against her womb. She could feel the dolphin’s dick pumping wave after wave of semen into her. The dolphin pulled out of her, leaving her gaping pussy leaking cum into the ocean water as it swam away. 

She lay there on the ocean floor, still completely stunned from the experience of being used by the dolphin. There was still a dull ache in her loins from being taken so forcefully, and she reached a hand down to probe her throbbing pussy. It hurt, but she couldn’t deny the pleasure she’d felt building inside her, although she hadn’t orgasmed. She inspected her hand; a web of sticky dolphin cum clung to her fingers, slowly dissipating in the warm ocean water. 

It was then that Kat realized her leg was free! Somewhere in the dolphin’s thrusting it must have shifted the rotten mast enough to let her pull her leg loose. Overwhelmed with the sudden realization that she wasn’t going to drown after all, she kicked and swam for the surface. She felt butterflies in her stomach: partly from the exhilaration of freedom, partly from the shame of being raped, and partly from a strange yearning in her loins that the experience had awoken within her. 

Still, now was not the time for self reflection. She kicked off the sandy ocean floor, and floated back towards the safety of the ocean surface. It didn’t take long for her to break the surface. She’d never been so happy to feel the sun beating down on her skin. She turned over, kicking towards the boat as she floated on her back, soaking in the sun. Her breasts bobbed in the water, her nipples like little buoys. She still felt that feeling of butterflies in her stomach; she wondered when it would fade. She’d have plenty of time to think about what it meant when she was back on shore.
