Your big sister

You recognize Lara's voice. She was also at home when you met... Him, and it looks like she didn't reappear far from you. She suddenly jump out of the shadows of trees and you can't help but widen your eyes.

Lara was always beautiful, but now she looks like a goddess. Her blond hair turned into a flamboyant mane. Her blue eyes are now piercing like ice. Her cheekbones are slightly more pronounced. She might be a few inches taller, and far more athletic. And her breasts are... well, first, they are bigger, and she was always well endorsed. Secondly, they are bare.

Actually, she's only wearing some sort of thong, and a look of determination you never saw on her face. You briefly wonder why the both of you are so sparsely covered, but your omniscience inform you that being immune to bruises, sunburns and low temperatures, humans only wear clothes out of modesty. You actually already crossed path with tribes in which nobody was wearing anything. In other, people were still covered from feet to head.

Anyway, your older sister is now standing in front of you, a harpoon in her hand, looking like some sort of jungle goddess. Despite being related by blood, you can't draw your gaze away from her tits and can't help but be thanful for your tribe's traditions.

"What happened? Are you in shock?"

You raise your head and babble "I... I just f... faced a fuckin lion!"

She suddenly relaxes.

"Ho, that's all? I was worried, I thought you were in danger."

You're about to reply when you realize that, indeed, you made the human body so tough that a lion could hardly hurt it. You sigh and try to regain your composure.

"Well, I was just... You know... It surprised me. It approached me from behind so when I saw it I was face to face with it."

She smiles and hugs you. You're frozen, stunned by the feeling of her massive boobs pressed against your torso.

"There, there, little brother. Who knows, maybe it's your animal spirit?"

You don't answer. You're suddenly wondering wether or not it would be ok to fuck your sister right now.
