Weiss contentedly hummed to herself as she lowered herself into the bathtub. The bathrooms each dorm was furnished with were surprisingly lavish – a full shower and tub equipped with spa jets did seem extravagant – not that the Heiress was about to complain. She'd locked the bathroom door of course; wouldn't doo to have Blake or Yang walk in on her by accident – she had her modesty to think of after all – so there would be no interruptions to her quiet, peaceful relaxation time… Right?

Wrong.

Blissfully vegetating in the nice, hot water as she was, Weiss didn't even notice the jet stop. Nor, under the soap suds, did she see the black mass beginning to extrude from the nozzle between her legs. Not that she'd ever admit it of course, but she had so positioned herself to have the jet gently pleasure her as she enjoyed the bath water at her leisure. Thus was it that she scarcely batted an eye when the appendage brushed her womanhood. In truth, the Heiress was half asleep in her luxuriant bath, and even as it began to worm its first few inches inside of her, she thought she was dreaming it even as her thighs reflexively closed a bit.

"Oh Neptune~" She drowsily moaned, "Go ahead… take me…"

As though in response to the invitation, the dark member currently exploring Weiss's entrance plunged deep inside, jarring her from her daze as she suddenly lost her virginity.

"Aaahh!" Weiss yelped, trying to stand up. She froze when she saw the black tendril protruding from her pussy, staring in slack-jawed horror. "W-what?"

When it pulled out slightly and then thrust back into her again though, Weiss's knees buckled and she fell back into the water, where more of the black tentacles were emerging from the bathtub's Jacuzzi nozzles and starting to wrap about her legs. Desperately, she tried to throw herself over the edge of the bathtub, but the tendrils tightened about her legs and she could only get her stomach over the lip. As she bent over to reach for the counter, or anything really, to pull herself out of the tub with, her petite, if still shapely ass made for an easy target, and a second tentacle swiftly availed itself of the unwitting invitation, sending a shock through her body.

"No…" The heiress grunted as she slumped over the lip of the bathtub and her body rocked forward and back in time with the thrusts into her ass and pussy, "Not… like this…"

Her hair was loose of her usual ponytail, and hung about her downturned face in a jostling cascade even as the plunging thrusts inside of her brought wincing tears to her eyes. Her breasts were small, but not so small that they did not jerk and jiggle with each successive penetration, slapping softly against the edge of the bath. She felt disgusted with herself when she realized that her nipples were hard, and doubly so when she began to enjoy the writhing appendages being inside her and allowed herself to slip back into the water, moaning softly as her head rested just above the water at the end of her bath, her arms hanging over either side of it. She moaned more loudly as two more tentacles spiraled around the first and entered her pussy, causing her legs to reflexively clamp shut, only to be thwarted as two more tendrils wrapped themselves around her fit, lean thighs and pried them open, lifting her feet from the water and separating her legs such that they draped over the edges of the luxuriant bathtub at the knees, leaving her womanhood and supple ass open for plunder.

As the various tendrils continued to surge in and out of her with impunity, the two remaining tendrils explored her upper body. One coiled about her right breast and squeezed, its slimy tip teasing her nipple and prompting her to still louder moaning. Dimly, she thought about how humiliating this would be if anyone else saw – or were even listening from out in the dorm – but Blake and Yang hadn't come back with her after Ports class, and by this point she was far too busy enjoying her violation to care. The last tentacle caressed her neck and slithered up her chin, before curving over like a snake poised to strike, and when next she parted her lips to moan in uncontrollable ecstasy, it dove down her throat, choking off her pleasured vocalization. It tasted salty on her tongue as it deeply probed her throat, but that was okay.. as long as whatever this was kept making her feel this good, she could forgive a lot…

She felt herself getting hot all over as the pleasure flooded her senses from her breasts, ass, and vagina, and slowly, so very slowly, she felt a kind of pressure mounting in the pit of her stomach. She wanted more of it – she had to feel it all – and she wanted it now. In a lazy haze, she used her semblance with a sluggardly twist of her wrist to cast a red-orange clockwork glyph around the whole bathtub area, and then let go. When the rune took effect, she lost her mind. Suddenly all eight tentacles fucked her all over in fast-forward. The creature hammered into her ass, it drove itself down her throat, the wet, slithering caress and constriction of her breasts became a forceful kneading, and her pussy… the three members wound around each other inside her had become a thick, writhing drill plunging deep inside her. It was all too much, and after just a scant few seconds of this her back arched and the tentacle withdrew from her lips, allowing her to scream out in ecstasy. It was so great a pleasure that, as her body arched, she was almost completely lifted out of the water, her whole body trembling and shaking above the bath as she orgasmed and a torrent of juices flooded out from her vagina. Then, having sapped most of her aura in the course of its ministrations, the creature withdrew all its apendages at once, dropping her limp body unceremoniously into the water again, leaving her eyes unfocused and her tongue lolling out of her mouth.

"T-that… was…" Nervously, she reached down to feel the fire between her legs, "A-amazing… What… was…" but she couldn't find the strength or will to finish her sentence, instead slumping and falling into a satisfied doze.

Well then, the unnamed tentacle Grimm strikes again, as requested (I think… I don't really read anything other than English) Weiss was the next victim… Thoughts? Want to see Blake and Yang? Others? I'm open to suggestions.
