Aria panicked, thrashing, trying to get her wrist out of the creature's grip. The muscled tentacle tightened, both around her hand and her leg, and jerked her beneath the surface again. Sea water covered her face, flooding her nostrils. The water rushed over her body as the thing contracted, tightening its grip.
Gotta relax, can't panic, or the thing will drown me, she thought, and forced her muscles to loosen, her body to go limp, to stop fighting against the monster's grip. She had no idea if it would work, except for the fact that if the thing wanted to eat her, it would have done so the first time it grabbed her. Instead, as long as she wasn't struggling to get away, it had seemed fine to let her float back up to the surface. And sure enough, it did the same thing this time, though from her struggle she had twisted around, back up towards the sunlight. She was able to lift her face to breathe, leaving her floating upright as if she were treading water, though she didn't dare move. She had one arm out for balance, the other pinned against her leg by the creature's grip. Her other leg dangled beside it, and she didn't dare move it, even when a second tentacle found her other foot and began coiling its way around it.
Heart pounding, chest heaving, she couldn't move as the things slithered up and around each of her legs, curling up her body. The creature seemed to be holding her upright, so she no longer needed to steady itself with one arm. Did it want her to keep breathing? Did it understand that she needed to? Aria tried to think, remembering what the concierge at the hotel had told them about the creatures. They were supposed to be intelligent, supposed to not prey on humans, but then why was it so interested in her? She looked around, anxious for someone to spot her, so she could wave and scream for help or rescue. But she was back behind the rocks. No one could see her. No one was close enough to hear her, not over the crashing of the waves against the rocky spires nearby. It was just her and this creature, one tentacle curling up the forearm pinned against her side, the other working its way along her inner thigh.
The second tentacle seemed thicker than the first. It pushed between her legs, sliding upwards against her body, curling around her hip. It pressed against her with surprising strength, pushing the fabric of her bikini bottoms along with it as it moved up from between her legs. She felt the suit pulled against her slit, her folds exposed to touch the warm, slick surface of the creature's tentacle. It moved slowly, pressed right up against her clit. With a stark realization, she realized it was pulsing against her.
Her cheeks reddened in the sunlight as the first little spark of pleasure sizzled through her nerves. Now was not the time, this was not the place, and yet, the thing was pushing against her, sliding slowly across her most sensitive parts, pulsing along her clit. There was such strength and pressure in its touch, and it pressed against her with such firmness. It felt good, and it shouldn't. It pulled her swim bottoms along with it, tugging them down her ass. The ties of her swimsuit, pulled tight against each hip, were slowly coming undone as the tentacle moved.
She had stopped struggling.
The end of the tentacle pleasuring her had curled around her waist enough for her to be able to see it through the water. It was an engorged pink, corded with muscles or ligaments, thick as her own wrist. It felt its way blindly over her body, curving up over her breasts.
It didn't break the surface. Instead, it continued moving, the thicker lower part of it still rubbing and pulsing between her thighs, as the upper end began encircling one of her breasts. It slid along her skin, ignoring the barrier of the swimsuit, pulsing against her nipple, in the same rhythm as the one pushing against her clit. A little moan escaped her throat at the new sensation, her breath growing heavy. The tentacle continued its path, curling around each of her breasts in a figure-8, shoving the triangles of her swim top aside, squeezing around her tits with a strong insistence. Her breasts and hardened pink nipples were now exposed to the sunlight. She tried to cover herself with her one free hand, but the tentacle curled around her wrist, trapping it against her chest as it continued to toy with her breasts.
The other tentacle, the thinner one that had first seized her wrist, had been steadily curling up her body as well, though she hadn't noticed it over the pleasure building below her waist. It had made its way up over her shoulder and now began curling around her neck with a light but insistent pressure, brushing against her chin, leaving a slick trail against her skin. Overwhelmed by the sensation between her legs and around her breasts, Aria had her mouth open, breathing heavily. The curious tip of the tentacle brushed against her lips, exploring there as it had the rest of the surface of her body. Without thinking, Aria pressed her lips against it, tasting its slick, salty exterior. When it pushed into her mouth, she let it, pressing her tongue against it, feeling it move against the inside of her cheeks and against her throat, wrapping her lips around it. The sensation was overwhelming. She didn't care how it might look.
A third tentacle had begun pulsing up her leg, against her inner thigh. This one didn't take the meandering, coiling path the first two had taken-- instead, it seemed to know exactly what it sought.
Aria was still being pleasured by the pressure against her clit, overwhelmed by the sensation of the waves lapping at her exposed nipples, the tentacle squeezing her breasts and pressing into her throat, that she barely felt it until she felt cold seawater against her bare opening. The tentacle at her slit had moved aside, pulling her swim bottoms away with it, and each of her legs had been angled apart. She couldn't do anything about it. The creature had entirely encircled her limbs, immobilizing her, and she was bare naked within its grasp. The third tentacle had made its journey up her leg and prodded at her entrance tentatively, finding the passage slick from her arousal.
It pushed inside her, and she gasped around the shaft in her mouth. Every coil around her thighs and breasts and waist tightened in reaction, ready to fight against her struggle, just as it had before. The one within her pushed in harder. Aria forced herself to relax, to let it pull her legs wider, to let it press further into her. As she relaxed, so did the coils of tentacle, but the one within her continued its exploration, pulsing and warm within her body
The tentacle curled around her breasts continued to squeeze, the one pressed against her clit continued to slide slowly upwards, as the third began to fuck her.
Aria moaned against the mass in her mouth, sucking at it. Her body was encircled by pulsing, coiling tendrils, holding her completely immobilized and helpless just at the surface of the water. She had never felt such overwhelming pleasure before, her entire body wrapped and filled with the creature's warm strength. So much so, that she barely registered the fourth tentacle, thicker than any of the others, sliding up her leg as she was being fucked.
This one found the last entrance to her body, pressing against her ass, finding much more resistance than either of the others had. When this one began to push against her, Aria clenched her muscles, resistant despite the pleasure. She tried unsuccessfully to kick away.
The creature didn't like that.
All four tentacles tightened against her, constricting and pulling her beneath the surface of the water. The one in her mouth forced its way down her throat, muffling her shout as the thickest tentacle pushed roughly into her ass, filling her completely.
The creature held her underwater, and she was unable to fight, trapped by coils of unyielding tentacle. The two in her ass and pussy were fucking her agressively now, as she was held fast by the tendrils around her thighs and waist and breasts. The sensation was more than she could bear, despite her panic-- the weightlessness, the feeling of being filled, the helpless way she was forced to give herself over to this faceless creature violating her so intimately, it was it was more pleasure than she had ever felt before. The two tentacles inside her began to pulse, the whole creature vibrating, and she felt her own climax begin to come. She felt them push even deeper inside her as the orgasm rocked through her body, making her feel like she had been stuffed full as they rammed harder and harder and the second wave of pleasure overtook her and the stars began to appear at the edges of her vision and--
