On the floor.

The worm wriggled up her bare leg leaving a trail of slime, before Lena shook it off. "Eeeek, little fucker is fast"

"Jesus, I told you that its dangerous. Where did it go?" Alex said. "Hang on, I'm going to smash it with a frying pan like I should have the first time. Just keep it away from you, I'll be right back."

Alex spun and darted out of the room, leaving Lena rapidly looking for the worm. Almost in an instant, Lena froze. Slowly she could feel her body relaxing. Calm came in a long exhale like a weight had been taken off her shoulders. She flet a strange confusion come over her as he heart began to pulse and her nipples hardened. She felt wet and the ruddiness that had held sway over her chest and shoulders, previously caused by her anger subtly changed and spread, now caused by a different and growing condition. Lina's face, recently filled with fear, passed through a blank stare and them morphed to one of lust. Now with a desire, a hunger, for a companion. She mewed and looked for Alex, biting her lip as she thought of his meaty cock taking her from behind.

She felt so unbelievably horny, a flush of heat radiated from her skin to her core, like she had just taken a shot. Lina felt heat growing between her legs. "Fuck Alex get back here" she panted, as one hand began to caress her clit. She grunted and inhaled sharply as she rubbed her engorged clit. She closed her eyes and continued to rub, gradually increasing her pace unaware that the worm had recovered and began to close in on her.

As as wave of pleasure rippled through her taut body she gasped and opened her eyes. The worm crawled back toward her, attracted by the heat emanating from Lina's now moist pussy. Lina, started to look at the worm in a different light, its translusent pinkish texture began to look more like a slick plastic sex toy and less like a freakish parasite. The entire process, so needed, so obviously necessary! Why had she been so upset with Alex, and so repulsed by her wonderfully cute new companion. She had no reason to fear! She had every reason to accept this openly and thankfully!

The slug drew closer, slithering rapidly on the ground. Lina bent upward at the waist, and grabbed the little thing, the slick skin felt pliable in her hand, but she had a tight grip on the thing. She paused for a second to check if the fear in her mind could countermand the burning need in her loins, but it could not. She got on her knees and hunching forward began to push the worm in and out of her tight wet hole. Holding it tightly she worked it in and out of her, driving her mad with the extrasensory stimulation.

" What the fuck are you doing?" Alex shouted from the doorway. he was holding a pan and was sweating panic.

Startled from her trance Lina shook, and momentarily released her grip. "I... its not what it looks like" Lina cooed. Then she looked down and saw the back half of her permanent guest disappear into her. Even as it did, the edges of the worm seemed to have started to transform based on its new host.

A further new wave of warm internal contractions, spasms really, washed through, around and over Lina as the worm crawled downward through Lina's cavern, in search of a deeper home. Lina could do nothing but moan and fall backward once more. The Churning in her pussy drove her mad as she began to thrash on the floor once more. The throng of ecstasy bombarded her consciousness. She could feel the worm squirming inside her tight passage as it moved deeper into her pussy. Each flail of the worms tail whipped at her senses and drove her toward orgasm.

Alex grabbed her arm and knelt next to her. Staring intently into her face.

Then Lina felt a strange twinge followed by a fullness, neither of which she had ever felt before, coming from somewhere high and deep within her canal. Not as a touch so much as an internal slightly weighted movement, Krissy felt her invited interloper crawling deep within her uterus. Each such movement, each contortion, brought a growing flood of excitement to her. Her womb seemed to be so full to her. Her vagina seemed to be throbbing, grasping inward, spasm after spasm. Her engorged nipples tingled with each breadth she took, almost begging to be massaged, kissed and suckled, having reached a rigidity, thickness, and coloring that she had never before experienced or even though possible. Her glowing red skin, now again covered in sweat, this time from excitement and no longer from fury. Her mind focused on the pure passion which was emanating from within her, and which was completely encompassing her. Her free hand, almost with a mind of its own, moved down to her own drenched slit and started to unashamedly slide along engorged labia and up to a throbbing and exposed clit. Lina reached for a blissful, crashing, complete, orgasm.
