In the cramped confines of their shared room, siblings find themselves alone and restless. The teen boy, clad only in boxers, can't resist the urge to touch himself, his cock tenting the fabric. His sister, hearing his soft moans, enters to find him stroking his length. Instead of leaving, she's drawn to the sight, her own body responding. She sits beside him, her hand tentatively reaching out to touch his cock. He gasps, but she continues, her strokes matching his rhythm. It's not long before they're both lost in their shared lust, the room filling with their soft sighs and the wet sounds of their bodies coming together.
