Sonic Girls ENF/Underwater Cave
Marine's mouth was as dry as sand paper when she woke up. She felt a warm puddle beneath her and rolled over, immediately scooping the liquid into her mouth. Her eyes shot open and she spit it out, a taste like melted plastic on her tongue. She looked down and saw the liquid was a strange pinkish substance with the texture of syrup. Her body was covered in it, up to her shoulders.
It took her a moment to realize she was still naked, and she instinctively covered her naughty bits.
Not that there was anyone around to hide them from. She realized she was all alone in a strange cavernous surrounding. She thought it was cave that is, but it wasn't one of stone. The walls were soft, almost fleshy in appearance and they were dripping sea water. Marine stepped out of the shallow pink pool and was immediately greeted with a piercing sting in her heel. She fell back with yelp, holding her throbbing foot and then noticed that the pool she was in was surrounded by jelly fish. They were everywhere, packs of them slithering along the wet floor of the cave like serpents, moving about with surprising speed.
Marine tucked in, bending her arms and knees close to her chest. She whimpered quietly, scared of another stinging attack from the monsters. She didn't notice that one was already in the pool with her and slithering up between her legs. By the time she felt its tentacles along her thighs the jelly fish already had its protruding phallic lined up with her twat.
Marine screamed and tried to leap out of the pool and was rewarded with a series of pulsing shocks along the insides of her thighs. Her legs gave out in the pain and she collapsed screaming back into the pool. Other jelly fished slithered along to the sides and held her arms down as the invading jelly fish pressed its phallic tentacle into her crevice.
Marine shrieked as she felt her walls spread open and the alien object burrow deep inside of her. Physically, a strange mixture of pleasure and stretching discomfort, emotionally a whirlwind of shame and fury. She kicked her legs, screamed and yelled for help, but the jelly fish just stung her with each show of resistance until she was docile and quiet.
Some of the jelly fish splashed the pink liquid into her face, smeared it into her nose and lips. Marine was disgusted at first, but a strange feeling soon washed over, a pleasing burning sensation in her stomach. She felt herself go wet and the tentacle thrusting into her become less uncomfortable. It moved more easily, slicker, faster, more pleasurably.
Marine was disgusted with herself. She couldn't really be enjoying this, could she? The feelings were undeniable though. Soon that overwhelming heavenly build up, which to that point she had only been familiar with by touching herself, was quickly reaching its peek and she couldn't hold back. Marine came. Her walls clamped down tight on the tentacle and she tilted her head back stifling a moan. The waves of pleasure coursed through her, more intense than her fingers had ever given her, and then faded as quickly as they came.
Marine went limp in the pool shedding tears, though she wasn't sure if they were in grief or pleasure.
Give in
Marine heard the voice as clear as a bell. She looked around but saw no source from which it could have come from. What she did see were more jelly fish starting to drop into the pool. She decided then too...
