The brother, perched on his bed, trains his Lite Periscope on his sister's room, his heart pounding with each illicit zoom. He watches as she undresses, her body glistening with sweat, her fingers dancing over her slick pussy. His own hand drifts down, stroking his hard cock in time with her rhythm. Their shared, silent connection intensifies as they bring each other to the brink of orgasm, their eyes locked through the lens, their bodies aching for release. The sister's low moan signals her climax, and her brother follows suit, his cum splattering onto his stomach as he watches her ride out her own pleasure.
