Morgana made her way carefully down to the lake. If her calculations were correct, and they mostly were, tonight she would be able to summon the great powers of the water and bend them to her will.
The moon was low and bright, making it easier for her to pick her way over the pebbly shore of the lake. She stilled, listening for a while to the soft breeze through the trees and the water lapping gently at the shore, and breathed a sigh of relief. Utterly alone, just as she’d planned. She drew out her grimoire from her knapsack and got to work.
By the time she had arranged all her materials, and marked her body with ancient symbols, the moon had nearly set, its silvery light rippling on the dark waters. She cast her cloak and gown aside, it would do no good to get them wet, and waded into the deep. Morgana had been practising her craft secretly for years and had learned many things, one she had never forgotten; a price must always be paid for your request, for power. With her dagger she sliced a thin cut across her palm, raised it to the sky and uttered the sacred words, then let the blood drip into the inky black lapping at her thighs.
She waited.
A few moments passed and a shiver went down her spine, but it was not for the cold. Morgana could feel a presence near her, something otherworldly and colossal in size shifting into being beneath the surface of the water.
She shuddered as she felt its first contact. A soft, slick tendril crept around her ankle and she struggled not to leap away in discomfort. It worked its way up her leg, squeezing and massaging as it went. Her eyes widened and she looked down in surprise, the tentacle was cupping her bottom just above the surface of the lake, probing over the globe of her cheek and then along the cleft to her other one.
“G-great Being,” she began, a little uncertain. “I make you this offering,” she paused to squeeze more of her blood into the water, “As payment for your loyalty to my mission-”
Morgana gasped as another long, wet tendril made its way round her other leg and curled its way around her belly. She forced herself to remain calm.
“To destroy Uther Pendragon and become Queen of all Albion,” she continued, her voice strong and clear despite a third tentacle tickling her wrist. She glanced at it and noticed tiny suckers kissing at her flesh.
There was no answer from the creature. She frowned. The Being was meant to be sentient, to speak to her so that she might strike a deal. I’ll have to check my grimoire, she thought anxiously and made her way to the shore to retrieve it. However, at her first attempt to take a step away from the lake, the tentacle around her belly tightened.
“Oh!” she gasped, trying to pull away but the tentacle held fast. She frowned, pulling her arm away from the other tendril that had secured itself tightly around her wrist, but it was no use. Morgana panicked, and attempted to make another dash for it, unfortunately stepping on a slimy rock under the water and slipping headfirst underneath. Immediately more tentacles leapt to her rescue, coiling securely around her back and shoulders to pull her head above the surface, then stroking down her neck and arms soothingly.
Payment, she thought. She had assumed in blood but how wrong she was. She lifted her free hand and absently patted the tentacle on her belly. Well it definitely doesn't seem to want to kill me. She had just had that thought when the tentacle which had been supporting her shoulders began snaking its way around her collar bones, up her neck, to her chin. She opened her mouth in shock and the creature took its opportunity to dip quickly inside, secreting something gooey and sweet onto her tongue and then slipping back out again before she had a chance to react. The substance tingled but was not altogether unpleasant, but the effect on her body was instantaneous. She positively throbbed with a sudden inexplicable desire to be touched, and the tentacles responded.
The one which had been probing at her buttocks stroked more firmly down between them, just as the one near her mouth slipped lower, its suckers leaving little pink circles in their wake. Morgana moaned as two simultaneously wound their way around her breasts and clamped onto her nipples. Two more coiled tightly around her wrists, pinning her hands away from her body. She panicked again as they pulled her towards the water, but it was not to drown her, only to make her float on its surface, the thickest tentacle still supporting her back and thighs from sinking.
She sighed when the water lapped gently at her sex, and then moaned as she felt the tip of yet another tentacle probe the top of her thigh. It stroked over up and over her pubic bone soothingly as the one on her buttocks began massaging in earnest at the same time. Another pair of tentacles wound around her ankles and pulled her into a starfish position, stretching her wide. Without any further ceremony the sucker of one clamped onto her clitoris and sucked, hard.
Morgana screamed in pleasure, her orgasm already beginning to build. The suckers on her nipples doubled down in their contact as the one at her mouth pushed past her lips again, perhaps to gag her or to secrete more of that sweet juice. At this point her mind was too gone to know. It filled her mouth fully, nearly choking her with its thick girth and pulsing movement, but the tentacle on her clitoris kept sucking away and she merely moaned around it. One more tentacle slowly wound its way around her straining neck, sucking more perfect pink circles into her tingling skin.
The muscles in her abdomen drew tight, a deep want blossoming inside her and her eyes nearly rolled back in her head as another thick tendril entered her aching sex. She arched her back as she was breached but the tentacles holding her wrists and ankles pulled her firmly back into place, the water lapping over her heaving chest and abdomen. This time her legs were stretched even wider than before, and the tentacle that had been playing with her behind poked at her hole. She tensed and the thick tentacle in her mouth produced more of that sweet nectar, immediately relaxing her and if anything making her push her bottom out - searching for touch. She felt it slide up against the cleft of her cheeks again and bucked as it trailed its suckers lightly over her entrance, again and again until she found herself rolling her hips with the movement. The tentacle inside her pussy throbbed in excitement and pushed its way deeper, finding an oh so good place inside and rubbing it unforgivingly.
She moaned again and sucked in earnest on the tentacle in her mouth, hoping to be rewarded, and for her release to finally come. The sucker on her clitoris had decided to tease her now, only sucking gently and in little bursts, as the one at her bottom continued to play. She could feel her hole pucker in response, welcoming the next intrusion of her quivering body.
The tentacles were slick, and though she was in the water, Morgana was glad of it, for when the tentacle finally thrust into her arse it was relentless and wide, oh gods so wide. She felt like she was being split open, and mercifully the tentacle on her clit knew this, because it picked up the pace and suction, distracting her body from the shock with pure pleasure. She wailed around her tentacle that gagged her, tears springing from her eyes and trickling down her face into the lake. The one inside her pussy rubbed generously at her g-spot, but the one in her arse just kept going. Deeper and deeper until Morgana felt she would break and then, exquisitely slowly it started up with a pumping motion to match that of the one in her pussy and the one in her mouth.
She couldn't take it anymore, her entire body contracted and was coming, so hard and with an orgasm that didn’t seem to ever end. Tears streamed down her face while her own juices mingled with the slick texture of the tentacles that invaded her.
Finally it was over, and in a daze she realised that the creature had deposited her on her cloak on the shore. She wrapped herself in it, shaking and exhausted and fell asleep. Conquering the world would have to wait for another night.
