Jenny closed her eyes and tried to ignore the shameful feelings of the three aliens stroking, groping and fingering her. She had no idea how long it lasted, it felt like an age, but it was probably just minutes. At some point, the finger between her legs, embarrassingly making her wet, disappeared and was replaced by something cold. She looked down to see the short alien inserting a glass device of some sort into her, then opening her up so it could look deep inside her pussy.
She closed her eyes again and gritted her teeth as it inserted a long rod, made of something that looked like black metal inside her, shoving it deep before beginning to circle her clit with one of its long, spindly fingers again. Jenny was horrified as she began to feel arousal swelling reluctantly inside her, and tried desperately to wriggle her hips away, but with the two aliens alongside her both now squeezing and twisting her nipples, she couldn't help the way her body was responding.
She was aware some flashing lights coming down from the ceiling, as though it was photographing or x-raying her lower body, but everything was lost in the deliriously horrible thing that was happening to her.
Then it all stopped. As suddenly as that, the two beings on either side of her let go of her breasts and stepped away, leaving just the smaller one examining her internally and stimulating her clit. After a moment, that one also withdrew the apparatus from her pussy and moved backwards. Finally the strange camera that had descended from the ceiling rose and disappeared back into the haze above her.
Then Jenny saw why they had moved. Another alien was approaching, and this one dwarfed even the taller ones. It was a good foot taller, and whereas the others were slender things, this one was massive. Monstrous, even. It had the same pallid skin but it's features were slightly more human, almost elven despite the large, black pools, like shark's eyes. But no, this alien had muscles. It rippled as it moved. It's arms thicker than most men's legs, and bulging with power. It's torso was equally large, almost bursting with strength, and then below its slimmer waist, its hips and legs were thick and strong-looking.
This alien was different to the others, perhaps a chief or some sort of warrior, she wasn't sure. What really separated it from the others though were the two long tentacles that seemed to emerge from the back of its shoulders, almost like long, thin wings.
It barked something at the three others, who stepped hastily into line. This one didn't speak a language she could understand, but whatever it said, it was exerting authority over the others. Then it turned its gaze on Jenny, naked and vulnerable, strapped to the bench. It loomed over her, a towering monster with an almost predatory look in its dark, evil eyes.
Jenny couldn't move her ankles, but she instinctively tried to pull her knees together as it walked into the space between her legs. Immediately the three other aliens stepped forward, and between them held her legs open again for their superior.
One of its tentacles reached upwards, seeming to grow longer, and then downwards, the tip of it trailing from her ankle upwards past her knee and along her thigh. Jenny screamed.
"Get the fuck off me!" she yelled, suddenly finding that she could speak.
The huge alien responded by snarling at her, and then extending the other tentacle. This one shot towards her head, and Jenny tried to turn away but before she even had chance to close her mouth, the tip of it, as thick as her wrist, was rammed in, hitting the back of her throat and making her gag.
She clamped her teeth down, hard, but the muscle was as hard as bone beneath the soft, grey flesh and the massive creature stood glowering down at her didn't even flinch. She bit as hard as she could, but the alien only pushed its tentacle further into her throat, making her gag reflex kick in, and realising she was about to choke, she let go with her teeth. The tentacle didn't move straight away, and even when it did, it began to move inside her mouth, as though it was getting a blow job. It certainly worked in shutting Jenny up.
The other tentacle was in between her legs now, the tip of it moving over her pussy and then across her slit, caressing and nosing around as though it was smelling her. It delved in to the unintentional wetness of her pussy for a moment, before withdrawing and travelling slowly lower until it reached her anus. Realising what was about to happen, Jenny tensed, but it was no good, the tentacle forced its way in to her tight little arsehole, filling her up totally. Still gagged, Jenny moaned with a combination of pain and- despite herself- arousal. The tentacle began to soundly fuck Jenny's compact arsehole and she found herself writhing. She gazed at the beast between her spread eagled legs and saw that its cock had slid out from the lump at its groin. It was huge, the size and thickness of a man's forearm, with a bulbous glistening head.
The smaller aliens held her wider open still, totally exposing her, so that her cunt was gaping open, wide and inviting. The alien crouched slightly and pushed the tip of his massive cock in to Jenny's moist, inviting pussy.
With the tentacle already embedded up her arse, it felt even bigger in her tight, wet cunt. She groaned loudly as the alien rammed himself deep in to her, stuffing her fuller than she ever believed possible. Held bound as she was and wide open by the sharply clawed fingers of the aliens, Jenny was unable to move much, but horrified as she was by this violation, her treacherous body began to buck towards the alien as he screwed her. He was fucking her harder now, brutally, the massive cock sliding all the way up her in time to the tentacle up her arse. The second tentacle was withdrawn from her mouth and Jenny felt a relief in her aching jaw. She regretted the withdrawal though, because as soon as it was removed, she was unable to stop herself crying out and moaning.
The tentacle worked its way back down her body and with the dexterity of a finger it began to circle her clit. The combination of the rhythm of the light pressure on her clit and the two massive appendages shafting her hard was too much. In spite of the situation, the fear, the fact that she was being used, taken so forcefully against her will, Jenny felt the orgasm building. She tried very hard to deny it, to stop it, but to no avail. The orgasm exploded through her body and she cried out loudly as she came harder than ever before in her life. Spasm after spasm rocketed through her and the alien timed his thrusting with her climax, so that his cock was embedded deep in to her cunt at each new wave. Jenny looked up at the alien and saw its eyes were open and staring at her. Then, without warning, the creature stiffened, its powerful shafting became shorter and quicker and it made a noise, high pitched and frightening. She felt it spurting inside her pussy, and the pressure of this forced a second orgasmic wave rippling through her body. The alien abruptly withdrew his cock and the tentacle from her arse and to her further shame, she felt some of his cum drip out of her. She relaxed her body and lay panting for whatever might come next.
A short time later, she couldn't tell how long, the smaller aliens gathered around her with a tray of equipment. Jenny was terrified once again, but then realised that they were only intending to clean her. They washed down her body with surprising gentleness, before inserting a douche in to her pussy and washing out the cum from the large alien. She felt the cool liquid fill her, a sensation equalled in its strangeness by the vacuous feeling it left behind as it rushed back out of her.
The big alien just stood there, watching her. It had wrapped a tentacle around its penis and was massaging itself. Jenny hoped it wasn't trying to get itself erect. Her clitoris felt sensitive, in fact her whole groin area felt slightly tender and well used. The thought of it fucking her again was daunting, but embarrassingly she also felt turned on at the prospect.
It snarled something at the smaller beings, the harshness of its voice making Jenny jump. It seemed to be giving them some sort of instructions. The aliens obviously deferred to it as their superior, bowing to it before going about their business. They surrounded her, releasing her from her restraints but before she could even attempt to make a run for it, the big alien's tentacles wrapped her arms, snapping her upright, and then pulling her arms behind her back and wrapping her wrists together. She was half-pushed, half-carried forwards, towards a bench which looked similar to the one she had just been bound to, but this one was on an angle. Jenny was pushed forward as she approached it, and landed heavily on it, face first. The surface of it was hard and smooth, and her breasts were crushed beneath her as the aliens slid her further on to it. Her head was at the lower end of the slanting bench, so that her ass was raised up and exposed to the big alien that was still standing back there. She felt her legs pulled apart and along with her hands, bound to the sides of the bench so that she was unable to move.
She was filled with fright, completely unable to move, or even turn her head fully to see what was going to be done to her, but as scared as she was, fear took on a completely new meaning when a door in the white wall before her opened. It slid upwards smoothly, without so much of a hiss, to reveal a darkened room beyond. Something was moving in there, but she couldn't quite make out what. As her eyes adjusted from the bright light to penetrate the gloom through the door, she began to make out another of the huge aliens, walking towards her, but there was something else too. Then, as it approached, she made it out, and her breath caught in her throat.
The beast, she couldn't think of any other word it, stood almost as tall as the large alien's shoulder. It had four legs, and was muscled like a huge, male lion but it's face was more wolf-life. It was covered in short fur, streaked white, grey and black and had several long, sharp-looking talons on each its four huge feet.
The thing saw Jenny, as it and the alien passed through the door and into the bright light of the room where Jenny was strapped down. A long, bright blue tongue lolled out of it's mouth, saliva dripping from its fangs, and it strained hard against the alien's leash, in an attempt to bound towards her. It's jaws snapped and it growled menacingly, and as it walked nearer, Jenny thought she was going to die here. Were they going to feed her to this monster?
The newcomer brought the beast past Jenny, making sure to keep it out outside of reach, and then paused to talk to the other that had just fucked her. Their speech was guttural and unintelligible, but it sounded almost as though they were laughing, or speaking in amused tones.
The newcomer alien passed the leash to the other, then squatted down and stared into her eyes. Jenny met them without blinking, trying not to show any fear and he grinned at her, revealing row upon row of sharp, needle-like teeth. It eyes moved sideways, taking in the sides of her squashed breasts, and it extended a long tentacle touching the back of her neck, before trailing the tip down her spine, making Jenny shudder involuntarily. It paused there for a second, the aliens smile slipping to a more serious expression, its eyes narrowing in what she presumed to be arousal, as its long, thick cock slid out of its groin like the others had.
