In the confines of their shared home, Nabe Boy and Nabe Girl, bound by blood and religious teachings, struggle with their growing attraction. One fateful night, Nabe Girl, clad in a sheer nightgown, accidentally-on-purpose brushes against her brother's arm. Nabe Boy, unable to resist, lets his hand linger on her thigh. Their restraints snap, and they're consumed by a fervent, forbidden passion. In the dim light of their bedroom, they explore each other's bodies, their hands trembling with excitement and guilt, their breath echoing each other's ragged rhythm, until they're both left breathless and aching for more.
