In the cramped, dimly lit space of the attic, the siblings, both teens, find solace in their own hands. The brother's strokes grow faster, his breath hitching as he watches his sister's hand move rhythmically between her legs. She moans softly, her fingers glistening with her arousal. The brother's cock throbs, aching to replace her fingers. They lock eyes, the tension palpable, as they continue to pleasure themselves, their bodies yearning for more than just their own touch.
