In a cozy, snowed-in cabin, siblings Ice and Icy find themselves alone and restless. Their parents are out, leaving them to their own devices. Icy, the elder, starts by stripping down to his boxers, the chill in the room raising goosebumps on his skin. Ice, the younger, watches from the couch, her eyes drawn to the bulge in his boxers. She starts to touch herself, the heat between her legs contrasting with the cold air. Icy notices and, instead of stopping her, joins in, his hand stroking his hardening cock. The room fills with their soft moans and the sound of flesh on flesh. Their breath fogs up the room as they lose themselves in their own worlds, the ice outside their window a stark contrast to the heat they're generating.
