Samantha was scared and completely puzzled at the same time. She stared at the strange thing that shared her cell with her, or stall, or whatever it was she was confined in. It had no door because the thing that was constantly fucking her held her helplessly in place, both through sexual ecstasy and with its strong tendrils or tentacles.
The strange aliens had attacked without warning, and she had been among a large group of young men and women that the weird looking aliens had selected from thousands of other prisoners. She and the others had then been loaded onto one of their spaceships, but she had no idea what had happened to the rest of her fellow captives. When the ship had landed on this strange planet she had been taken to some sort of large complex and examined and the aliens had performed all sorts of what she guessed were tests on her, some very unpleasant. But they hadn't really hurt her or anything. Then she had been taken to another building and led out on a platform which was surrounded by raised tiers of benches full of aliens, like an arena. She had been stripped of her clothes when captured, so was still nude when she was put on display and sold, because it could only have been an auction. And more humans and other "things" had been auctioned off as well as she watched from a cage. Then the alien that had bought her had brought her to this strange farm, or whatever it was. When she first arrived; and was being led by her owner to this stall, she had seen pens full of all sorts of weird animals in pens of some kind. Some were pretty recognizable, or at least similar to animals she knew, but some were totally bizarre.
When she'd arrived at the stall she found some more of the aliens waiting for her and they had a strange looking thing with them that looked like a great big dark pinkish purple slab of meat with leathery skin more than anything else, it had a kind of broad fleshy looking pedestal for a base with some tentacles of something like them around its center, but she didn't see any eyes or a mouth. She didn't even realize it was alive until they led her up to it and it suddenly extended two fairly short thick penis shaped stamens (?) out of a mouth like opening in the top. And she had screamed and cried; begging them not to, when they had forced her to sit on top of the thing and be impaled in her vagina and asshole by the twin penises, because that's certainly what they felt like as they slid into her. The penetrations weren't especially painful as the cocks were covered with thick slippery mucus, but the sheer suddenness and bizarre setting had freaked her out big time.
Once the weird things penises had penetrated her to the hilt in both her vagina and asshole the aliens had held her struggling body in place until the thing had sprouted several large vine like tentacles and wrapped them around her thighs, waist, and arms to hold her helplessly in place. As soon as the rape started the aliens had left her alone with her "lover". The tendrils had tightened and loosened several times as they moved around, evidently trying to find the most comfortable position for both of them under the circumstances. Then once the thing was satisfied with its grip on her it had started fucking her, but it held her firmly in place and it didn't move at all. Evidently the penis like tubes it had inserted inside of her contained its actual penises which were huge, and were now pistoning in and out of both her openings in a steady rapid thrusting rhythm. She had struggled at first at the horrible violations, but it was useless and before long she stopped trying to get lose and could only moan and gasp in pleasure as orgasm after orgasm rocked her body. The damn thing was insatiable, and it sure could fuck. She had to admit she never been fucked so thoroughly before. And she could feel it as it spurted its sperm; or whatever it had, deep inside her body again and again. And not a single drop ever leaked out, whatever it was she was keeping all of it in her. For two days it fucked her nonstop, then gradually slowed down, and then stopped. And now that she was no longer dazed and almost delirious from sexual ecstasy she realized something very wrong was happening to her.
