As the sun peeks through the curtains, a brother and sister awake, their breaths shallow with shared guilt. They've played out their fantasies in the quiet of dawn, their hands exploring each other's forbidden territories. Today, the tension is palpable; they're both hungry for more. The sister's nipples harden as she imagines her brother's mouth on them, and he can't help but think of her tight, untouched cunt. They're both virgins, but their bodies betray them, aching for each other in the soft morning light.
