Eternal Hearts Ch. 09

"How's that feel, sis? How's it feel to have a tentacle inside you?" Dannii teased with a smile, her fingers working expertly at her own pussy as she watched the show before her.

"It's fucking incredible," Kylie breathed, just rocking up and down with him using her toes as best she could. He started to speed up, pumping briskly into Kylie's sweet pussy and making her tremble with pleasure, absolutely loving the smooth feel of him inside her, twisting and exploring her as he fucked her, something Kylie had never experienced before, turned on hugely by the fact she was fucking another strange creature so soon after having mated with a werewolf. He was really speeding up now, Kylie gasping for unnecessary breaths as he slammed into her, jolting her body as he really started to pound on her, his thick tentacle hard and deep inside her. Kylie felt a funny, deep sensation and wasn't sure what he did, but suddenly he surged several inches deeper inside her, making her inhale sharply at the strange but not unwelcome feeling as he eased her cervix open and delved into her womb.

He chattered excitedly at his new depth, and after a few experimental thrusts resumed his previous pace, pumping Kylie hard, fast, and deeper than ever before as she grunted primally on him now, never having been fucked quite like this, plundering the pleasure inducing qualities of her body so completely. He gave some clicking sounds from the darkness as he tensed a little, making Dannii think he was very much enjoying himself as he pounded on Kylie, who was struggling to keep pace with him. So much so that he started to lift of her off her dainty, size-three feet, making her give a decided grunt at the sensation, twinged with pain. She didn't stop him though as he continued, clicking in frustration that he couldn't pull her body down onto him to bury more of himself. He pounded her hard, Kylie grunting hard with every lift, now to about a foot off the ground by her pussy and some other tentacles encasing her legs, but she never complained, completely lost to the moment it seemed.

He explored her completely, his thick tentacle having already fully checked out her vagina and now deep inside her womb, bending and pushing inside her, like he wanted to know every possible millimetre of his latest lover. Dannii could see her older sisters tummy bulge slightly as she was filled totally by the powerful tentacle, making her pause and stare a moment, especially since he wasn't going what she'd call particularly hard on her, knowing just how strong he really was. Kylie couldn't speak now even if Dannii had asked her something, so she just watched on as Kylie rode and bobbed on his thick tentacle, stretching and screwing her like she'd never been in her life.

As he continued to pump hard on her, other slender tentacles were squeezing and feeling at Kylie's incredible ass, loving how firm it was and pulling her cheeks open to expose her completely, though she barely noticed in her state. His tentacles teased up her arse, pressing and teasing at her tight back hole in an effort to penetrate her and double up. He clearly wanted in and it didn't go unnoticed by Dannii's sharp gaze.

"You have to show us you're a good boy first," Dannii teased, "so if you're naughty you won't get to nail her sweet arse."

He gave a few clicks in slight annoyance but kept ploughing her pussy, Kylie gasping and grunting hard now, evidently loving it and approaching an orgasm. He gave a tight squeeze on Dannii's breasts, making her gasp, to get her back from holding him back on Kylie's sweet arse, wanting that more than her pussy now.

"You can do as much as you like to her arse without penetrating her though," Dannii offered with a grin, knowing he'd very much take that up. He immediately went to town on her older sisters' booty, well back to town, since he'd already been working at it. His tentacles took a firmer, more complete grip on her peachy bum, something so many people wanted to do, and squeezed at her, taking in just how toned she was, her entire body tight and pleasing for him. He continued to fuck her pussy hard as he did this, still lifting her up as he concentrated on her rear, his tentacle stroking and teasing at her arsehole as she gasped through her stiff fucking. Kylie was very hot now and closing in on a climax, when Dannii stepped things up.

"Clicks, stretch her, pull her out tight," she commanded, meaning to pull Kylie out by her limbs, since her pussy was already being well stretched.

"Dannii hey I don't..." she started, trying to protest as his tentacles took a firmer grip on her ankles and wrists and didn't wait, doing as Dannii ordered and pulling her out in a star-jump position, just stretching her out to the limit as he continued to jam himself into her pussy, which tipped Kylie into an orgasm at the strangely erotic sensation of being so thoroughly dominated. Her climax was hard, making her whole body jerk in his strong grip, her pussy clamping tightly round his thick tentacles. He knew exactly what was happening, and how to get the best out of her it seemed. Still holding her spread eagle, he hammered her pussy hard and fast, getting her G-spot with a curve of his tentacle and somehow knowing how to make her moment of ecstasy inaccessible to her till he chose, building her up hard till she was gritting her teeth and whimpering at the imminent explosion.

With a last flurry of thrusts inside her, he suddenly yanked out of Kylie, who exploded with a huge scream of pleasure and a large squirt of several feet across the warm cave floor. Kylie gasped and shook with pleasure at the massive, overwhelming orgasm, another couple of minor squirts ejecting from her before the rest of her juices just leaked and dripped to the floor as he clicked approvingly, very pleased she had squirted so successfully. He gave her a moment to recover, then fairly jammed his thick tentacle back inside her still clenching pussy, making her cry out as he started to fuck her again, Kylie's body very sensitive in the wake of her orgasm and unable to stand such treatment.

"That's enough pleasure, now it's time for some pain," Dannii said, having slowed her ministrations on her clit to prevent herself from coming, wanting Clicks to do that for her.

"But Dannii, I'm exhausted," Kylie breathed, pouting and wanting a break now as he slowed in her.

"Shut up. I want to see her impaled by just her pussy," Dannii said, ignoring Kylie's pleas for mercy. He gave a series of clicks from the darkness, then filled her completely with his thick tentacle, tensing inside her to hold her and then releasing his grasp on the rest of her body to let her hang solely by her pussy. Kylie put her arms out to steady herself, feeling very unstable on just his tentacle, combined with the sensation of just her most delicate areas supporting her, feeling every inch of him inside her.

"How does that feel then?" Dannii asked, loving playing the arbiter for Clicks and Kylie.

"It feels...I can't really explain how it feels. It's so full and intense, nice but uncomfortable, it's just...unique. You really need to try it," Kylie said, looking over to Dannii in the twilight of the cave.

"Sometime soon perhaps," Dannii said with a smile, before Clicks took hold of Kylie again, using her arms and legs to pull her up straight and expose her body, which her started to whip firmly with a slender tentacle, making Kylie shiver.

"Oh god yes," she breathed, goose pimpling all over and shuddering in his grasp, loving the light, playful bondage aspect right now. She continued to gasp and moan her way through the whipping her gave her, not going too hard, just enough to give a light sting and leave some red marks across her incredible body front and back. She was particularly vocal when he caught her nipples, making her firm, perky breasts jiggle perfectly as he caught them with the flick of his tentacles. He covered her whole body and tight arse, making her bite her lip in pleasure as her submissive side was delighted.

"That'll do," Dannii said, making Clicks stop whipping Kylie, who gave a sigh and a final, tension releasing shudder as her body felt almost glowing in the effective silence of the moment. A thin tentacle slid to her face, caressing her gently with a loop of it, making Kylie lean into him intimately, before he pulled away and gave her the closest thing to a smack on the face. She breathed heavily as she pulled her head back up, being greeted by the tentacle again, this time the tip of it tracing her soft lips, running round them a couple of times and avoiding Kylie's attempts to get him into her mouth. His tentacle pulled back, then in a movement so fast Kylie couldn't see it, he flicked it forward and expertly split her bottom lip, making her gasp and jerk back at the sudden, sharp little pain, feeling a rush of excitement course through her as a trickle of warm blood ran down her chin. Kylie was shocked and exhilarated by it, sucking her bottom lip and tasting the rich, metallic blood on her tongue, feeling herself awakening in a new fashion deep within despite not needing to feed.

"Her ass is all yours," Dannii said, smiling and giving a little stretch on her tentacle seat, a couple of his tentacles now caressing her smooth legs, which she was allowing.

"Oh fuck yeah," Kylie groaned, relishing the idea of him taking her anally after what he'd done to her pussy. He immediately went for her, grabbing and squeezing at her arse, spreading her wide to rub over her tight back hole before letting her go again, giving a few firm whips with his tentacles to make Kylie squeal. He quickly took hold of her again, keeping her legs well spread and then spreading her arse again, stroking more firmly over her arsehole, feeling how it yielded to his pressure as Kylie relaxed to accommodate him. She was very experienced with anal sex, and knew how to easily take something in, and right now she was very eager to do so, and gave a groan of pleasure as after a little more teasing he pressed at her anus. He pressured slightly, then gave a little pulse and the surface of his tentacle became slick, lubricating himself, which immediately made him slide into Kylie's sweet, tight arse.

He was using a thin tentacle to begin with, sliding easily into her, feeling her working to let him in with her trained muscles. She gave a murmur as he relubricated part way in, feeling him pulse and go slippery again, surging deeper inside her. It was a new sensation that was for sure, and she found it strangely enjoyable to accompany the deep, satisfying sensation of something in her arse. Kylie groaned as she felt him explore and delve inside her, going very deep, feeding his flexible tentacle into her at a surprising rate, inducing very weird and interesting sensations within her as he essentially explored her arse, wanting to do more than just test whether she'd stretch to take anything larger and besides, she'd already told him she did anal sex. With her being quite loud, he raised a thick tentacle to her mouth and slid it in, Kylie greeting it with her tongue again, more of a challenge this time thought. She licked and circled him with her tongue, just being allowed to tease him a moment before the slit at the end of his thick limb captured her tongue, sucking it into the end and massaging it, almost like someone sucking at it during a kiss.

After it released her tongue she yielded and let him pass, sliding effortlessly down her throat and making her tremble in sensation as she was slightly overcome, quickly regaining herself through as he held in her throat, leaving her to suck and work at him as best she could as he continued to explore her ass. Kylie just hung in his grasp as he worked deeply inside her, his tentacle teasing at areas inside her she'd never reached with any toy or lover, making her squirm in a mix of pleasure and other sensations. He somehow seemed to know where to touch her deep within, having an incredible sense of direction that was getting her quite hot again.

"Go as deep as you want," Dannii said, encouraging him to continue doing what he was doing, seeing the strange expressions Kylie was pulling. Kylie's toes and feet squirmed, her legs kicking and tensing a little at her very revealing anal exploration, feeling quite embarrassed now as he had what seemed to be his fun with her body, leaving her a little shy at feeling so turned on, her pussy dripping wet again now. He was clicking his enjoyment of it however, and then changed things by lowering her towards the ground, Kylie's dainty feet touching it, followed by her knees as her shaky legs buckled under her own weight. But that was fine, as he wanted her down doggy style, lowering and guiding her onto all fours on the cave floor, Kylie actually feeling quite relieved to be down on the ground again.

With her down, he posed her easily like his own living doll and then secured her effectively, wrapping her at the ankles, just about the knees, her waist, shoulders, elbows and wrists, making it entirely clear what he was going to do to her by leaving her hips and arse completely unobstructed. Another slid round Kylie's smooth neck, coiling it to prevent her from looking round but not squeezing while at the same time his other tentacle slipped back out of her mouth. There was a slight shifting noise from the darkness and Dannii looked up, not seeing him but sensing he was much closer, just outside the ring of light they occupied. And then she saw something else, his cock, his actual member, not just another tentacle, and her eyes widened, a gasp escaping her mouth as she looked at the impressive specimen before her.

It was unlike any cock she'd ever seen before, understandably, prominent on the end of a thick tentacle, and around a foot long and about three inches thick, probably a bit more. But it wasn't a smooth shaft, it was ribbed, going in and out in a series of steps about three inches long along its length, going from its thickest at over three inches down to around two, perhaps less. At the tip of it was a tapered head, looking fit to break through anything it liked, with a thick back ridge that looked like it would expand or flare to a much larger size, something like a horse might. Dannii would know all about it when she got a chance to explore it more, but frankly it was like some very exciting sex toys she'd used in the past. It was hard to tell for sure though as it pulsated in the flickering light of the cavern. She wondered what biological need would decree an evolution to such a design, but then she realised you couldn't really quantify the biology of such an alien creature and decided not to consider it, simply thinking about how that would feel inside her, and how it would look when he plunged it into Kylie, which was clearly his next intention. Kylie though couldn't see it, facing away from where he was wielding it and restrained, leaving her completely oblivious to what was coming.

"He's seriously got something for you, Kylie," Dannii said, unable to hold the excitement from her voice despite knowing it'd be a huge challenge for her sister, who could barely accommodate a quarter of it.

"Really? Am I gonna like it?" Kylie asked, quite a worried sound to her voice.

"It'll be intense, but I think you're gonna absolutely love it," Dannii said, shifting on her tentacle seat as her pussy begged her for attention, her thoughts of letting him penetrate her with that monster cock ravishing her mind and making her once more reach for her pussy, following her neat arrow of hair to her clit. Her fingers started to idly massage her clit as she gave a soft sigh, squeezing her thighs a little as she watched Clicks' tentacles slide from deep in Kylie's ass, his grasp coiling all around and over her tight, petite body as she was restrained doggy style before her, awaiting her fate. Kylie murmured at the sensations as he withdrew his thick, exploring tentacles from her body, having felt something like never before as his grip on her tightened. Dannii watched the strain in his limbs as he squeezed her sister tighter, making Kylie whine a little.

"That hurts," she mumbled, attempting to shift in his hold. He responded by squeezing the tentacle around her neck, the strong flesh cutting off her ability to protest with the slightest squeak from the singer. He gave a click from the darkness as he held her dominatingly, pulling her knees a bit further apart to spread her even more in readiness to penetrate.

"Stop, that's too much," Dannii interjected quite urgently, breaking the rhythm that had been building. Clicks knew what she meant evidently, as he released the tentacle around Kylie's slender neck

"It's OK," Kylie breathed, trembles of arousal present in her voice, "do it harder. Just don't break anything," she finished. After a pause, clicks let his grasp on her neck slacken and then snapped his tentacle tight once more, harder to give a sudden shock before his sustained hold on her, making the diminutive blonde shiver in excitement at it, her unnecessary breaths cut off as he restrained her so completely, a helpless fucktoy for himself. His huge cock swept in closer to her, under ultimate control from the thick supporting tentacle as it lined himself up with her tight, toned ass, seeking to split her in two.

"Take me closer," Dannii whispered over her shoulder, though it may as well have been to the general gloom around her. It was heard regardless, and she was effortlessly moved nearer to the action on her chair of entwined tentacles. She had a front row seat to her sister and lover spread helplessly before her as the long, ribbed cock lined up with her slick opening. The tentacles restraining her rippled with strength, squeezing at her thighs as his cock just made contact, letting Kylie have her first feel of the sheer size of his as he pushed gently at her already loosened, waiting hole. She couldn't make a sound however as Clicks started to work his way into her, rolling his tentacle behind it to open her up, his head squeezing into the petite popstar, clearly knowing what he was doing as Kylie's body resisted him. Dannii marvelled how he was clearly very experienced with human females as he seemed to have the mastery of their bodies, just applying the right pressure to stretch Kylie's tight ass open. There was a final moment of building power and then he popped inside her, his thickly ridged cock breaking through and being greeted by the silky squeeze of her sphincter, eliciting a clicking growl of pleasure from him and the slightest gasp from Kylie as he slackened his grip on her neck in the process. She took the initiative to clamp down tightly with her muscles, gripping his cock exquisitely tight and making him throb and swell slightly in her ass with a clicking sound.

"Oh he liked that," Dannii said with a smile, knowing her siblings' penchant for anal sex and the techniques she had developed with it. Kylie smiled a little internally, happy to be able to please despite the unknown quantity of the encounter, her tight little body able to deliver even with such an alien cock inside her. Relaxing her body, her sphincter loosened around him to let him penetrate her deeper, clicking noises preceding him slowly but powerfully sliding his cock inside her body for the first time, Kylie punctuating the proceedings with little squeezes of her sphincter muscle even as it was stretched wide over every ridge of his deeply ribbed shaft. It was a unique sensation for her as she stretched wide for his head, then squeezed down tighter again in the first taper of his cock, before being immediately stretched again by the next wide rib of him. It was stretching her ass to the limit but slid in with a smooth, controlled motion, his strength and power able to prevent any sudden jolts of his shape.
