Two tiny teens, a sister and brother, find themselves alone and bored, their curiosity piqued by the sight of each other's developing bodies. The petite sister, a perfect 18-year-old, can't resist the urge to strip down, her small frame accentuated by her perfect ass and perky tits. She fingers her tight, untouched pussy, her brother watching from the doorway, his massive, hard cock struggling to stay hidden. They tease each other, their voices barely above a whisper, their bodies aching with forbidden desire.
