In the dim light of their shared bedroom, a brother and sister, both in their late teens, find themselves alone and bored. As they each retreat to their respective corners, they begin to masturbate, their soft moans filling the silence. The brother, his cock hard in his hand, catches his sister's eye as she fingers her wet pussy, her other hand squeezing her full breast. Their shared gaze ignites a spark, and they slowly move towards each other, their bodies aching with unspoken desire.
