Sister and brother's secret cam session heats up.

In the dimly lit room, sister and brother log into their cam-to-cam chat, a secret they've kept from their family. As they start to play a game of truth or dare, the questions become increasingly intimate. The sister dares her brother to show her his cock, and he complies, his massive member throbbing at the sight of her. She tentatively touches herself, moaning softly, as he strokes himself, their eyes locked on the screen.
