Original Sin: Genshin's Hidden Passion

In the world of Genshin, a brother and sister, both travelers, find themselves in a secluded, mystical cave, away from the prying eyes of Mondstadt. The sister, a succubus, feels her lust awakening, and her brother, a diligent and pious man, can't help but notice her growing arousal. As she leans against the wall, her hand slowly tracing the curve of her hip, he can't help but steal glances at her swaying breasts. She catches him looking and smirks, her tail flicking suggestively. "Do you like what you see, brother?" she purrs, her fingers inching towards her panties. He hesitates, torn between his duty and his desires, but her wet, inviting scent fills the cave, pushing him over the edge.
