Behind closed doors, the nephew's desire for his aunt consumes him. He masturbates furiously, envisioning her in his mind's eye - her sultry voice, her scent, her touch. His hand works his throbbing cock, from base to tip, smearing pre-cum. He grunts, feeling his balls tighten, and with a final stroke, he releases, his cum spilling out, a tribute to his forbidden lust, dotting the photo of his aunt that he keeps hidden away.
