Forbidden Fruit: Sister's Initiation

In the dimly lit hallway, a curious sister spots her brother's closed door, the faint moans piquing her interest. She inches closer, pressing her ear against the wood, her heart pounding as she realizes he's masturbating. A rush of curiosity and desire courses through her veins. She tentatively pushes the door open, revealing her brother's naked form, his cock hard and throbbing in his hand. Their eyes meet, and instead of shame, they find mutual lust. She steps inside, closing the door behind her, ready to explore the forbidden territory of incestuous pleasure.
