Melanie pushed her sister down onto the bed and straddled her. She was already down to her deceptively pure white bra and panties, while Miltiades, good, obedient girl that she was, had stripped down to just her crimson knickers, knowing her place… This was their every night after all – a long evening of standing in heels looking pretty for the revolting clods that went in and out of Juniors club was stressful, and stress was bad for the skin… Melanie, for her part, could think of nothing better for relieving that stress then to fuck her own reflection until she screamed…
Looking back as she slipped a hand into Miltia's panties and nibbled her ear, Melanie reflected that the first time might technically have been rape, but Miltia hadn't exactly resisted, so she never worried about it too much. It had started off innocent enough – well, as innocent as two seventeen-year-old sisters showering together could be anyway – and Melanie had offered to wash her younger twin's back. From there though, something had possessed Melanie to press her wet, naked form to her sister's back and wash her front too…
"U-um… Mel…"
But Melanie hadn't listened as she scrubbed her sister's stomach and moved higher… She remembered in close detail the way that Miltiades had squirmed when her fingers had closed around her younger twin's breast… and the thought that it was exactly like hers had made her so wet…
"Hey Milly… You're still a virgin, right…?"
Melanie didn't remember what her sister had said, but she did remember confirming the inquiry herself when she'd slipped her fingers inside…
"Mel… stop…"
Miltiades didn't tell Melanie to stop anymore… she knew better. And what was the harm really? They were both girls, after all, so there wouldn't be any real consequences, and Melanie saw that look in her sisters eyes whenever she took her – the 'it's only wrong if someone sees' look – and she knew Miltia loved it, no matter how much or how often she begged her sister to stop. Melanie knew that her sister – however she might protest – wanted her too – more even. Melanie wanted her sister because she wanted to see herself writhing in ecstasy, but the more bashful Miltia wanted her elder sister to have her because she wanted to be wanted – by who was of secondary importance. Naturally then, caring big sis that she was, Melanie was happy to routinely… bolster her sister's self-esteem…
Melanie wasn't quite sure at what point in her reminiscence that she'd stripped off her panties and then her sisters, but she didn't mind that. She minded even less that she hadn't quite been aware of when she'd entwined her legs with her sisters and pressed their pussies together, starting the grind slowly at first… As she felt her folds rubbing up against her Miltia's, Melanie's vision blurred at the pleasure, and she began to lose track of where she ended and where Miltiades began. Bliss… Yet bliss was abruptly supplanted by anti-climactic nothingness, and Melanie's frustrated eyes slowly opened, coming into focus in search of the reason that her sister had withdrawn from pleasuring her, and when she saw, her eyes widened in horror.
"Melan-!"
But Miltia's scream was silenced as a slimy black tendril drove down her throat. Long, pulsating black tendrils bound Miltia by the arms and still more of the grasping arms had begun wrapping about the younger twin's thighs, pulling them open by force, spreading her wide and putting her dripping wetness on display for her dear big sister.
All Melanie could do was stare as her body writhed in terror and she let out suffocated squeals. Melanie couldn't help but lick her lips as she watched her sister's smooth body struggle and undulate in the grasp of the… whatever it was – the way her thighs tightened and relaxed, the way her breasts shook with her struggling, and the helpless way that she fought it… so hot…
When a tendril reached up to claim Miltia's womanhood though, the spell cast upon Melanie by her own – her sisters –naked, writhing body was broken, No… She's MINE! Melanie lunged across the bed as the tentacle entered her sister, grabbing and yanking it back out before proceeding to take its place with her own fingers.
"Shhh…" She whispered in Miltiades's distressed ear as she jerked and struggled in vain, "It's alright little sis… I've got you-," But Melanie's reassurance was as hollow as it was unhelpful, for at that very instant, two tentacles plunged into Melanie from behind and she jerked forward, burying her face in her sister's breasts as she cried out, "F-FUCK!"
Having thusly claimed the elder twin, the tendrils swiftly set upon the younger once more, now unimpeded by sisterly possession. Indeed, Melanie had gone from possessor to possessed as the thing took her in the ass and pussy at once, and her zone of perception was reduced to the soft swell of Miltia's breasts into which her face had been pressed, and as if to underscore to the elder twin whom it was to which her precious baby sis really belonged now, it had returned to despoil Miltiades with three times as many tendrils as before, with two in her ass and four in her soaking wet pussy. Shakily, Melanie took her sister by the shoulders so as to pull herself up, resolving to resign herself to their mutual violation if she could just nibble her sister's ear and pretend they were alone again, but when she parted her lips the end of the tendril binding one of Miltia's arms reared up and dove down Melanie's throat, thus completing the simultaneous penetration of every adequate orifice the sisters had between them.
The tentacles lifted them off of the bed as they fucked the pair beyond rationality, and slowly, a pair of tentacles began to wrap themselves around both sisters. It started about Melanie's hips, slowly slithering around her back and then reaching across to Miltia to do the same to her, and it wasn't long before the pair were being held together, pressed close by the tentacles as though both twins had been stuffed into one corset, facing each other's naked forms. Their smooth, flat stomachs were pressed together by the constriction, as were their decidedly curvaceous breasts, the friction passing between them as they were fucked on alternating beats causing each girl's nipples, bare stomach, and clit to rub vigorously against the other, but no matter how close they got, they couldn't moan, because their mouths were both still full of wriggling tentacle. Juices had been steadily trickling out of both sisters since almost immediately after the tendrils had first beset them, but as the pumping in and out of all their holes intensified, and the two sisters were more vigorously rubbed up against each other, both let out a muffled cry of ecstasy when first Miltiades, then Melanie discharged an orgasmic torrent past the tentacles which even still persisted in their violating ministrations, their cum soaking the bed as the pair was steadily fucked into unconsciousness.
So, how's that – not only for tentacles, but for some hot twincest action too? I do realize that I kinda made Melanie a bit… well… crazy-possessive (or just downright crazy) but I thought it added a little something… Although I do hope that didn't offend any twins who may or may not be reading… Anyway, we're coming up on time for gender-bent Jaune, but first, next time we'll be doing something a little different; you see, Kiko Gorgon, eminently helpful brainsstormer, submitted an OC with the request that I have the tentacles (among others) rail her silly, so next time, that's exactly what's going to happen… and it's gonna be rough… At any rate, as always, requests and suggestions are welcome, and I do hope that you continue to enjoy yourselves with the fic~
