Herman and his sister, both infected with a rhythmic, primal funk, can't resist the urge to grind on each other in close quarters. Their bodies move in sync, their breaths heavy with desire.

Their hands explore each other's bodies, tracing lines of pleasure, before they're interrupted, leaving them yearning for more.
