Alone in the house, a brother and sister find themselves in a game of truth or dare. As the game heats up, so do they. When it's her turn, she dares him to touch her breasts. He hesitates, then complies, his hands tentatively cupping her mounds. She moans, arching into his touch. When it's his turn, he dares her to suck his cock. She looks at him, then at his tented pants, and with a mischievous smile, she kneels before him, taking him into her hot, wet mouth.
