Two young teens, left alone in the house, find themselves in a game of dare that quickly escalates. They start with innocent touches, but as their bodies respond, they can't help but explore further. The girl's hands tremble as she reaches out to touch her brother's hardness, her eyes widening at the size and heat of it. He groans, his hips bucking slightly as she tentatively strokes him. They're both inexperienced, but their bodies seem to know what to do, their rhythm building until they're both breathless and panting, on the edge of a discovery that will change everything.
