Under the cloak of night, a timid girl and her virginal brother sneak out to the family's ancient oak tree, rumored to grant wishes to those who perform a secret ritual. As they stand beneath its gnarled branches, they confess their hidden longings, their voices barely above a whisper. The brother, driven by primal instinct, reaches out, his hands trembling as he touches his sister's breast. She gasps, her body arching into his touch. Their first kiss, clumsy and eager, marks the beginning of their descent into a world of taboo lust, their innocence lost as they give in to the tree's ancient, carnal power.
