Quite effectively

Jane stared deep into those emotionless orbs. The stench of the creature filled her nostrils. It smelled like rotten meat and burning sulfur all mixed together. The monster lowered itself to her face and Jane could see deep into its fanged mouth. She still had one arm and one leg free. She knew she wasn't beaten yet.

Jane unclenched her free hand from the tentacle and maneuvered it behind her back where her daggers waited. She wrapped her fingers firmly around the leather grip of the blade. Immediately the feeling of the weapon in her hand made Jane feel strong. At the same time, she bent the knee of her unbound leg and pulled her foot along the ground closer to her body. She pressed her foot firmly against the stones beneath her making sure she had a strong position.

The creature's probing in her nether regions began to intensify. Jane could feel the strong limb pressing against the metal chastity belt guarding her womanhood. The long appendage pushed against the unyielding metal between her legs repeatedly, but the garment held fast.

Unable to make progress toward its goal, the creature shifted its attention to the clothing covering Jane's groin. That was when she struck. Jane set her jaw and pushed hard with her bent leg. The effort made her scream through clenched teeth, but she managed to push herself off the ground. Still clinging to her body, the monster was sent off balance and began to tumble. The beast refused to release its prize and pulled the young woman off the ground as it fell.

Her weapons no longer trapped underneath her body, Jane fluidly pulled the dagger from behind her back. She left the monstrosity no time to feel fear as she plunged the blade deep into its body. For a moment, she wasn't sure that her thrust had found its mark, but shortly the writhing tentacles fell to the floor. The creature stopped quivering. And Jane allowed herself to breathe deeply.

She had done it. Jane had survived her first encounter with a tentacle monster. She was exhausted and her muscles ached. She was sure she could have done better, but the task had been completed. She was proud of herself. She had rid the world of a terrible threat. There was no telling what might have happened it that thing had managed to get someone pregnant with it's abominable children.

Jane quickly set about the process of disposing of the remains. Part of her oath was to hide the horrible truth from humanity. People would not understand and could not handle the existence of such terrible creatures. It was important that no one ever find what she had faced in the old sewer this evening.

Her duty finally done, Jane gathered her weapons and prepared to leave the dark, foul-smelling catacombs.
