A young female sergal cub was wondering through the woods one day, having wandered quite a ways from her tribe, her loincloth fluttered in the wind as she walked. Being lost she keeps trying to retrace her steps and find her way back to her home, unaware of the beast that was stalking her, she being only a 10 year old cub with copper colored fur and white highlights on her hands, feet, tail and belly. She finds a lake and takes a break for a moment, rubbing her poor tender paws and murred softly. Then she goes to the lake and takes a drink all while the creature that stalked her slowly approaches her from behind, it revealing itself to be a giant slug like creature with a light blue body that stands out clearly as its green and yellow tentacles waved about. She then finishes her drink and wiped the water from her muzzle, then all of a sudden the green and yellow tentacles lashed out and grabbed onto her arms let's waste and tail and pulled her onto its back, she yelled and struggled as the creature held her in a tight grip. The two eye stalks near the front of the creature, presumably the head, looked at her as her loincloth flops about, exposing her young virgin sex to it, it gurgled in approval as it pulled her closer to its body as one of the thicker tentacles on it's back rubbed against her sex teasingly to test it. The young sergal blushed deeply and let out an involuntary moan of pleasure as her sex was being toyed with, the slimy appendage feeling undeniably good for the cub as her sex starts dripping her juices all over it. The slug grunts and gurgled as it tasted these fluids and took them as a sign of approval and the tip starts pushing into her tight body, stretching her out slowly as it went deeper and deeper into her, making her moan loudly and grit her teeth as she bares the discomfort of being stretched so far. The invading member then encounters a blockage and it keeps pushing against it, the cub groaned and grinds her teeth as she feels the pressure growing until it finally gives way and with a loud wet POP! her hymen breaks and the invading creature continues to push in deeper and deeper, her belly bulging clearly with the tentacle inside her and showed its every move and twitch. She pants and moaned loudly as she had never felt such pleasure before in her whole life, inside her the tentacle reaches another barrier in the form of her cervix. She pants and moaned in pleasure as it pulled the tentacle out of her a few inches and slammed back into her, making her arch her back and moaned loudly from the rush of pleasure. It then pulled out again and slammed back in, the end trying to break through her cervix, it slowly does this over and over again, making the sergal moan loudly in pleasure as her belly bulges with each and every thrust. The tentacle squirms around in her as the monster continues to fuck her hard, she bouncing on top of it and getting more and more in love with the pleasure it caused her. She tries to sit herself up to try and ride the thing better, wanting more of it inside her, she growing ever closer to her climax, feeling its slimy skin under her and felt the slime ooze from the tentacle inside her, lubing up her love tunnel better than her own juices. She grabs at the ones holding her arms as she was getting high off of whatever was in the slime the creature was pumping out into her, causing her judgement to become greatly impaired as all she wanted was the pleasure the creature gave. THen with one last thrust it breaks through and the first 2 inches of the tentacle poke into her womb and causing her the biggest climax she ever had. her cunt clamping down on the tentacle and soaking it in her fluids. She moaned and pants as she rides out the orgasm, but she has very little time to enjoy it as she felt a round squishy lump get pushed into her. The lump was about the size of an apple and she felt another get forced into her. Each one stretching her tight sex a bit more and popping into her womb, she looked down at the tentacle deep inside her and watched as the bulges move along its 2 inch thick length into her. her belly bulging as it entered her body. Slowly they start making her belly inch bigger and bigger, she moaned and gasps at the strange feeling, her belly growing rounder as the soft squishy eggs entered her, quickly giving her a 2 month pregnancy look alread. She just stares at the clouds and smiled. "Oh great gods above thank you for giving me this wonderful gift, I shall honor this creature and its young." She the arcs her back and yelled in pleasure as she came on the creature again, her belly showing no signs of the eggs inside her, and by the time her belly reached a full term pregnancy look her belly button popped out from the pressure inside her womb. She moaned as she was allowed to rub her round pregnant belly and could still feel it growing, the eggs inside shifting around to make room for the new eggs, she just layed there on the creature, drunk off the pleasure and watches her belly get bigger and bigger. Eventually looking like she was carrying twins. "Ohhhhh don't stop, fill me to my limit, I will take as many of your children as I can hold." She says to the creature as it keeps filling her, not understanding her words one bit, her belly growing bigger past the twin size and was closing up on triplet's, her belly growing tighter and tighter as she is filled, moaning loudly as she watches her large dome of a belly continue to grow, under her fur stretch marks pop up in random places but aren't too bad. Her belly soon creaked slightly as she reached the triplet size and the creature pushed one last egg in before it stopped. She had came so many times before this that she had passed out from it all. The creature then takes her off it and lays her on the ground, finished and satisfied with its work it moves on to find another mate and propagate its species. Meanwhile the young cub just sleeps off the amazing romp she had, her belly creaking very slightly as she breathes slowly, her new passengers tucked away facely within her sacred life giving organ. As she young sergal sleeps she dreams about her new friend and her body responds to this and her loincloth gets soaked in her juices and inside her massive belly the eggs begin to mature, their growth accelerated by her body heat, the eggs then slightly twitch every now and then as the larva inside get bigger. By the time the sun started setting she wakes up and stretches, but is shocked by the sight of her massive pregnant belly, she timidly rubbed over it as she feels the larva twitching inside their eggs. "By the gods....that wasn't a dream, I really did get filled with a monster's young." She feels just how tight her belly is and flinches when it creaked. "Ouch. looks like that thing filled me to the brim, I better find my way to a cave or something for the night." She grunts as she rolled her massive bulk over and used a tree for balance, groaning as she holds her huge belly and staggered to keep her on her feet. She then starts waddling off in a random direction hoping to find a cave or something, anything to wait out the night in. Dut to her luck she happened to find her village and smiled. "Ohh thank the fates." She waddled through the small settlement and heads for her hut, all of the other huts were all made from old escape pods from passing ships that flew over the planet, she getting a lot of looks from her tribe members as she walked into her hut and closed the hatch. She signed and walked into her large pod, it being decorated with all kinds of tribal nicknacks, and like some of the pods they all had power still but most of the features were badly damaged. She crawled into her hammock and hauled her massive belly up with her, laying there and rubbing it gently, lost in thought about what happened in the woods. "Is this really a gift from the gods? or some lucky coincidence? And what was that slug thing? I know it wasn't hostile or i'd be dead right now." She yawns and pulls the covers over her, luckily her blanket was large enough to cover her new size. "Well whatever it was i'm going to bare its children, I just wish I knew how long it was till they hatched." She gets comfy and slowly falls asleep for the night, murring softly in her sleep. But as she sleeps the larva mature more and more in their eggs, causing them to grow slightly and made her belly creak a bit as a result, and with how fast they were growing it wouldn't be long until they hatch.
