Two siblings, one a curvaceous teen, the other a lanky youth, find themselves in an awkward situation. She's trying on clothes, her body barely concealed by scraps of fabric, when he walks in, catching her off guard. Instead of apologizing, he stares, his gaze tracing her ample curves, his eyes widening at the sight of her pert nipples pressing against the thin material. Flustered, she covers up, but the damage is done. Their dynamic shifts, each aware of the other's body in a new, tantalizing way.
