In the dim light of their shared room, the siblings' hands roam, discovering new territories. She guides his hand between her legs, pressing against her wet panties, a soft moan escaping her lips. He responds by grinding his erection against her hip, their bodies moving in sync. Their clothes start to come off, revealing young, eager flesh. He takes her nipple into his mouth, sucking and teasing, while she strokes his throbbing cock, her inexperienced touch driving him wild. Their bodies entwined, they lose themselves in their first taste of each other, their moans filling the room as they cross the line from sibling play to passionate exploration.
