Hidden away in the dim light of a closet, a brother and sister succumb to their secret longing. Clad in modest attire, their bodies betray them, nipples hardening, breaths growing ragged.

Their bodies move in a rhythm as old as time, driven by primal instincts, until they're left panting, their secret safe, for now.
