Anya had never expected something so exciting to happen when she first touched the mysterious runes. Flipped on her back and suspended in midair, her arms were restrained behind her, her calves and thighs bound together and spread wide, allowing ample access to her luscious, dripping holes. Only minutes ago, she had been in a mountain cave, having hiked deep into the forest, following clues left in ancient texts. She could still see the bright pink glow that had filled her vision, the tentacles appearing almost out of thin air before her. She had been searching for traces of an ancient magic, an art only hinted at in ancient historical writings. When she found the runes, she was almost drawn to them, her presence activating the power that had remained sealed away for centuries. She knew what she was getting into, but she couldn't help herself, she wanted - no, needed - to know.
Log Entry 0034-5:
After initial contact and receipt of consent, the tentacles transport the female partner, or host, via portal to a pocket dimension, the transit removing all regular contents of their bowels and slightly altering their genome and physiology. These alterations allow their orifices and cavities to expand far beyond usual limits, provided the stretching occurs gradually to allow their body time to physically adjust. The stretching process produces pleasure rather than pain, often causing orgasms during penetration. Exposure to tentacle excretions, such as slime or semen, can have the same effect on the genome, in addition to amplifying the sensitivity of erogenous zones and heightening lust and libido. Up to a certain point of exposure, changes to the genome can be gradually reversed if desired by the host after returning to the normal world.
After reaching the portal dimension, the tentacle being restrains and disrobes the female, gently toying with her sensitive parts. The atmosphere of the pocket dimension contains a light aphrodisiac, causing her to experience heightened arousal, her pussy dripping wet by the time the tentacles have finished removing her clothes. And thus the fun begins.
Chapter 1
The first tentacles had been very basic in form, a simple taper and little in the ways of texture or detail. Caressing them, Anya had marveled at their soft skin, letting them curl around her fingers. Their small form was surely not to be underestimated, she could feel their firm, unyielding strength even as they gently entwined her hand, as if to pet her in return. Others soon appeared, larger now, and taking a more familiar form. Feeling her pussy moisten, Anya kneeled in front of the glowing wall, her head level with the tentacles. Opening her mouth, she wrapped her lips around the largest of the bunch, her tongue running over the head of the tentacle, pleasantly surprised at its slightly sweet taste. She quickly lost track of time, her free hand wandering into her pants, rubbing herself as she bobbed her head back and forth. Anya knew she wanted more, she had been searching for this moment for years, and wasn't about to waste it. Pulling back, she wiped her lips with the back of her hand, unbuttoning her shirt and pants as she presented her petite, toned form to the tentacles. The soft words "take me, please" just barely left her lips as the tentacles advanced, needing no further instructions, deftly snaking around her body, slipping easily beneath her clothes as it pulled her into the glow.
Back in the present, Anya found herself in a pleasantly warm, slightly damp atmosphere, dim light seemingly illuminating the dark around her out of nowhere. Her naked body was fully restrained by the tentacles, her private parts easily visible, were anyone around to see them. She knew she should probably feel quite vulnerable, but her excitement and lust were too great to overcome. Small, tendril-like tentacles approached quietly from below, wrapping gently around her exposed body and beginning to caress her nipples and clit, slowly sliding ever further between her puffy labia. She shivered and writhed to little avail at this torturous teasing, bucking her hips ever so slightly and moaning.
Sensing her lust, the tendrils at her nipples retracted, as two oddly pointed tendrils poised themselves above her small but perky breasts. Anya looked at the new tentacles quizzically, half curious, half frightened by the prospects of what they might be planning. She was not left to wonder for long, as the tips of the tentacles split open like a flower, four lips curling back to reveal an interior of tiny, writhing nubs and an orifice at the center. Each appendage latched eagerly onto her breasts, the orifice engulfing her sensitive nipples and beginning to apply suction in a rhythmic pattern, as the tiny nubs wiggled and massaged her sensitive skin. She gasped at the sudden, intense stimulation, barely noticing as the nubs at the edges secreted a sticky substance, firmly adhering the tentacles to her boobs.
Determining her pussy to be sufficiently wet, four of the thin tendrils rubbing her wriggled their way inside, eliciting another slight gasp from Anya's parted lips. They explored for a brief moment, reaching her cervix and brushing against it, then tickling the orifice. The tendrils began to excrete a thin, slick mucous, lathering it on her cervix as they brushed back and forth, the chemicals and stimulus causing the tight ring of muscle to relax.
Simultaneously, some tendrils began to take note of Anya's hitherto un-attended anus, and began to massage her rear, excreting more of the thin substance. As she moaned and gasped yet again, a penis-like tentacle poised itself in front of her face. Realizing its intent, she opened her mouth wide, inviting it, begging it to violate her mouth and throat. Wriggling with pleasure, the tentacle happily obliged, filling her mouth and allowing her to run her tongue over its smooth surface, giving it the lubrication it needed for what was about to come.
The tendrils at her anus, satisfied that her muscles are ready, prodded their way inside, still excreting their relaxing goo. After a short time of wiggling around in her colon, the tendrils slowly began to stretch her anus open, six tendrils pulling outwards, gaping her wide. A larger tentacle, tapered at the end and lined with patterns of ridges and bulges, poised itself behind her, patiently waiting for her hole to stretch large enough for the bulges to fit inside. Seeing this, Anya's eyes widened, cheeks flushing with heat at the realization of what was about to happen. Just as the tendrils reached the right point in spreading her ass, the thick tentacle plunged forward, slithering into her rear as her eyes rolled back with pleasure.
Anya barely managed to groan before the tentacle in her mouth, now thoroughly lubricated, pushed its way down her throat, her eyes shooting open again in surprise as it slid into her stomach, the writhing tip occasionally creating a visible bulge in her belly. The tentacle in her ass hadn't stopped, slowly slithering its way up her large intestine, the bulges and ribs popping through her anus one at a time as it ventured ever further. Reaching her small intestines, it paused for a moment, then pumped out a large splat of relaxing mucous, beginning to massage it into the transitional opening. At the same moment, the tendrils in her vagina pushed their way into her womb, beginning to spread her vagina and cervix open in much the same way as the others had with her anus. Moaning around the tentacle writhing down her throat, she shivered with pleasure, her mind beginning to numb as she reached the cusp of her first orgasm.
The tendrils at Anya's clit had not ceased their teasing, and as the tentacle in her ass pushed on into her small intestines, she finally succumbed to a massive, shuddering release, squirting her juices as her eyes rolled back, toes clenched and fingers grasping at nothing, struggling to break free of her bindings as she convulsed with wave after wave of intense, heated pleasure.
The release of fluid from her urethra, now visible with her dripping pussy spread open, attracted the attention of a thin tentacle with a slightly bulbous tip, which briefly prodded the small opening before slipping inside. Reaching her bladder, the tip of the tentacle unfolded, latching in place inside her. Another, similar tentacle, this one much larger, took advantage of her gaping pussy, pushing in, pistoning back and forth as Anya quickly reached orgasm for a second time. With her cervix still held open, the tentacle surged into her womb, unfolding and releasing a sticky goop, sealing itself firmly within her uterus.
Her belly now bulging and writhing as the tentacle in her ass reached her stomach, Anya noticed the tentacles beginning to quiver in an odd rhythm within her holes. Then she saw them. Slight bulges, working their way rapidly down each tentacle, quickly approaching her stuffed orifices. She shuddered as the first bulges pushed inside her, the tentacles in her mouth, womb, and bladder each erupting in blasts of tentacle semen, soaking her innards with their seed. At that moment, the bulges of the tentacle in her ass began moving. She barely noticed as the first egg, round and about the size of a golf ball, was ejected into her stomach, but soon realized what was occurring as they began to pile up, expanding her petite waist even further outwards.
Having filled her womb and bladder entirely with semen, the tentacles stopped pumping, giving Anya brief respite. She gasped as the tentacle in her throat retracted, quickly returning to moaning as the eggs in her stomach continued piling up, the tentacle now retreating, filling her intestines with eggs as it leaves.
Turning her upright, the tentacles continued to massage her body and distended stomach, the tentacles in her womb and bladder remaining firmly in place. Over an indeterminate period of time, during which she slipped in and out of lucid sleep from exhaustion, the seed pumped inside Anya seeped into her system, keeping her nourished and preparing her for the next ordeal. The eggs within her intestines grew more and more energetic as the hours passed by, and her breasts expanded slightly as they started lactating, much to the delight of the tentacles latched onto her, which milked her eagerly as the flow increased. At some point, the eggs reached the peak of their energy, some transforming into slimes while others hatched into tentacle wormlings.
Some hours later...
Woken from her shallow slumber by a strange wiggling feeling in her stomach, Anya felt the first of the tentacle spawn push at her anus, struggling to break free. Instinct taking over, she strained, pushing the first handful out, shuddering and moaning with pleasure as they wriggled free. Over the next half hour, she pushed her newly hatched clutch out into the world between orgasms of pleasure, with a few strays wandering up her throat, much to her surprise.
