Deeper into the worm

You look down at the golem and for a moment feel an urge to mount the monstrously huge tool which still stands out as if aroused. You guess that the insides of this creature has some kind of aphrodisiac gas and take mental note not to trust your urges.

You turn away from the golem and decide to go deeper into the worm, after all if you exited it's mouth it would probably just eat you again.

The acids cause your skin to tingle from head to toe, not having a scrap of clothing on you means you have no protection against the burn, but you are confident that it will not actually kill you. However starvation, suffocation or dehydration might.

You try to think if you know anything about the anatomy of a worm, hoping that this thing has some similar structures. Ridiculously you do remember some information and you don't like it.

The only ways out you can think of would be thought the sexual organs, or the digestive system. To get to the sexual organs you will need to cut your way there and crawl out. Worms are hermaphrodites, so you could go for the female entrance, it's cunt, or the male entrance, it's cock. Those are near the head so not to far but through some flesh.

The digestive tract on the other hand would make you have to go through it's bowel and out it's arse, and is at the furthest point in the creature's body.
