First step

"Hello there little fella". Cassie had handled snakes before and she saw that it wasn´t one of the venomous types. The headshape was different even though she didn´t recognize the pattern on the body.

She picked it up to examine it closer, careful not to give it a chance to bite her. All snakes still had fangs.

"Strange skin", she noted to herself and brought it even closer to her face.

In a mere second the snake lashed out at her and went for her mouth.

"MMMMMPH!"

Her mouth were full of snake and despite all of her frantic efforts to pull it out or to chew it to bits failed. It was either suddenly too slippery or too squishy to bite through. More and more of it entered her mouth. 

She felt how it pressed against the back of her head and how it pushed through in an explosion of head pain.  

She felt how it moved up to her brain, and down her neck and spine.

Numbness spread though her body and her field of vision was gradually becoming narrower, until it was completely black. 

The fallen body of Cassie struggled up on her unsteady feet again.

She was pleased.  This body and memories was highly sufficent for her mission.

With it she could court humans in positions that could interfere with the plans of her people. Replacement and infiltration had been the key to success in other subjugations of popualated planets with sentient lifeforms.

This world would be no exception.

Paradise Island

So far it had been an amazing vacation at the tropical paradise island. Her collegue Linda had been rather pushy about this particular island because she had visited it a couple of months before, but in retrospect, it had been the right choice.

"Hello little friend"

The small slug slithered slowly on the leaf. She envied it in some aspect. It didn´t have to bother about the things that happened all over the world, it just needed to mind its own business, living a slow life.

She sighed loudly.

Out of nowhere the slug jumped at her, and with pinpoint accuracy leapt into her mouth!

Victoria tried to claw it out from her mouth but it burrowed out of reach into her instead.

"Oh no. It´s in my head!", she panicked. 

A splitting headache made her buckle, and after a couple of seconds more everything went black. 

 

`Victoria`looked around.

`She´ had yet not full control of this body. 

Handling the sensations of a human body did still take much of ´hers´ mental capacity.

Body first. Mind later.

´She` removed one of the straps to the bathing suit. The wind that touched the nipples of the host created a spike in the nervous system.

The mind melding had begun in earnest. With a bit of curiosity ´she` removed the rest of ´her` bathing suit and exposed the body to the elements. 

The rays of the sun warming ´her´ skin, and the cool breeze chilling the "nipples"?

Fragments of Victorias memories began to surface. This host was a female member of the dominant species on this planet. 

The mind merging had progressed far enough so she could be able to pass as a human in their society. Within four day and night cycles, "days", she would be able to interact with this bodys acquaintances without raising suspicion. Which fit the time frame of "one weeks" vacation well. 

 The whole island had been seeded by infant members of her species, and just like Linda from her work she would coerce people to take a vacation on this island to supply more humans to their merging of species.
