In the quiet of their home, the siblings find themselves alone and restless on humpday. Their eyes meet, and without a word, they understand. They gravitate towards each other, hands exploring, lips meeting in tentative kisses. The brother's hands find their way to his sister's panties, while she strokes him through his boxers. Their pace quickens as they strip each other, their bodies pressing together, their moans barely contained. In the heat of the moment, they forget everything but their desperate need for release.
