Under the tree

It's less than ideal, but at least you don't have to worry about crossing the river. The ground is softer than the solid rock you would likely get in a cave, too.

Crawling under the exposed roots, you get a bit dirty, but that's inevitable when out in the wild.

You eventually get comfortable and drift off to sleep.

During the night

It awakens. Its olfactory organs tell it there is a large, female mammal nearby. It would not have awakened otherwise.

It slowly pulls itself out of the mud by the river, and slides in the direction the smell is coming from.

Another scent reaches it. One of its siblings is also awake. Its journey has just become a race.

It slides across the ground as fast as it can. Still not fast, but the best it can manage. The loser of this race will have spent a lot of energy for no reward. They may even starve to ****.

An hour later, its destination is just ahead. Its sibling is a few body-lengths behind, but this one is already at the feet of its goal. Unless its sibling can move half-again as fast, the prize will be this one's.

Its sibling seems to realise this too, turning back to find a deep patch of mud to hibernate in until the next time it is awakened.

Slipping under the strange not-skin that surrounds its target's upper legs, it prepares itself for entry.

The thin piece of not-skin which covers its goal proves to be a momentary obstacle, the openings to either side allowing easy access. Finally it slips inside, squeezing up the tight passage, and into the wider cavity beyond.

It has made it to its new home.

Now it must sate its hunger.

You wake up early, to a burning sensation in your pussy. You want sex. No, you need sex. You know that your fingers just won't cut it. You need a man. Any man.

You scramble out from under the tree and look down at yourself. Why are you wearing clothes? Those will get in the way of you having sex. You tear them off, leaving a pile of shredded rags as you head off in search of something to fuck.
