A sound awakens her, but it's too late

Outside the cave, the first signs of the coming dawn lit the horizon, the sky turning a dark shade of grey. A short ways off from the cave mouth, a creature sniffed the air, and smelled something amiss. Tracing the smell, it followed it towards the cave. As it approached the mouth, it saw several small, bare footprints in the mud. Another sniff, and it was certain that something was in its' cave, something to eat. As it entered the cave, another portion of its' brain caught up to the first part, connecting the footprints outside with the smell emanating from the cave. Human female. It would mate.

Venus awoke with a start, as something scraped against the floor near her. She rolled to the side, hand reaching for her sword, as she tried to shake the haze of sleep from her mind. It was, however, much too late.

Just before her hand grasped her sword, she felt something graze by it, kicking her sword to the far corners of the cave. A massive, scaly hand wrapped around her wrist, another grabbed her shoulder, and she was slammed against the stone pile she had leaned against. Venus howled in pain, even as she tried to free her other hand, to no avail. This creature was far stronger than she was.

Looking up, all she could see was a faint outline against the brightening cave mouth, a massive, shadowy hulk blocking most her view. From what she could tell, it looked like a mutated lizardman, the scaly hands grabbing her supporting that idea. She struggled in its' grasp, frantically trying to free herself, but she couldn't find a way to release its' grip.

The lizardman suddenly lowered itself, aligning its' hips with her, and she used her free hand to punch the creature in the face. It did more to her hand than it did to the lizardman, however, and she swore, before it abruptly thrust its' hips forward. She yelped in surprise as a massive cock slammed against her pussy, before forcing its' way through her dry lips.

She squealed in pain as it **** its' way in, tearing her hymen in the process, before it began pounding in and out. Venus fought to remove it from her, planting her feet against its' hips and pushing against it with all her might, but it just ignored her, continuing to hammer in and out. Her mind screamed at the violation, and a faint, "Please, no." escaped her lips.

Despite her efforts, her body betrayed her, the first signs of it being her juices starting to run. The scaly cock was rubbing against her clit, sending little jolts of pleasure to her tormented mind. The hand grabbing her wrist released it, moving to her breast, which it roughly groped and kneaded as it continued to pound her.

Venus moaned, surprised at how full she felt, and how good that felt, and her hips bucked against the cock, establishing a rhythm in tune with its' motion. Her hands moved with a mind of their own, one finding her other breast, kneading it, pinching at the hard nipple, the other finding and stroking the massive pair of balls that were slapping against her thighs.

It wasn't long before it came, releasing a massive load into her womb. She came with it, screaming with tormented pleasure, her toes curling against the lizardman's scaly hide. Her juices mingled with its' cum, leaking around its' enormous member, as her pussy spasmed one last time against the cock within it.

The lizardman pulled out then, standing up. Venus lay on the floor, gasping, cum leaking from her gaping pussy, and splattered on her inner thighs. Part of her screamed to find her sword and strike the beast down. Another part basked in the pleasure of what had happened. That had been so wrong, and yet so right...
