Caught Masturbating, Sister Dares Brother to "Fuck the Shit Out of Her"

In the throes of self-pleasure, a step-sister fails to notice her brother's piercing gaze through the keyhole. She's a vision of indulgence, her body glistening with sweat as she rubs her clit, her breath ragged with desire. He watches, captivated, until she catches him. Instead of shaming him, she invites him in, her voice laced with challenge. "You wanna replace my fingers with that big cock of yours?" she purrs, spreading her legs wider, daring him to give in to their forbidden taboo.
