You keep a close eye on her

As the two of you traversed the landscape, you made certain not to let her out of your sight. In particular, you studied the way she moved. Her pace was steady, like that of someone who had experience in walking long distances. She would not tire soon.

You also learned more of her physique. She was athletically build. A slender frame, but with curves in all the right places. They were very easy to notice in the skintight bodysuit she was wearing.

You didn't know of many people who had green hair, but she was one of them now. It was clear that her hair was not artificially colored, for her eyebrows were green as well.

The last thing that you noticed was a bulge in her suit between her legs. It betrayed that she was a hermaphrodite. A person who was born with the body of a woman, but gifted with possessing a cock as well. This spelled great danger to you, for you were a hermaphrodite as well. A person born with the body of a man, but cursed with possessing a vagina. If you weren't careful, she might not only fuck you, but actually impregnate you.

Eventually, you reached the river you had set out for. You tasted from the water and found it drinkable. You and Doe filled your canisters. You also found some berry's grew near the river. Doe tasted them, and told you they were edible. While she harvested some of the berry's, you were able to snatch some fish from the river.

You had discovered food and water. Now it was time for the next step of survival.

"So, what about shelter?" Doe asked you.

"Well." You said. "We could always go back to the ship. But travelling from the ship to this river and back again every day is going to be exhausting."

Doe cocked her head "So you suggest building a shelter here? Sounds reasonable."

"That, or we continue on to the mountains where this river originates. We could find a cave near it's spring."

"Each of these is a good suggestion. Which do you choose?"
