In a twist of fate, a curious sister stumbles upon her brother's hidden porn collection, fueling her own forbidden desires. She seeks him out, her heart pounding, and finds him studying. As she sits beside him, she can't help but notice the bulge in his pants. She tentatively reaches out, tracing the outline of his big cock with her fingers. He freezes, then turns to her, his eyes filled with a mix of surprise and lust. She leans in, whispering, "I want to see it. I want to touch it."
