Hidden in the closet, the siblings succumb to their taboo desires. The brother's massive, virgin cock stands at attention, while his sister, trembling with religious guilt, can't resist the urge to touch it. She sinks down, her tight, untouched pussy enveloping his shaft as she rubs herself along its length. Their father's voice echoes in their minds, but they're lost in their forbidden lust, collapsing in a mess of smeared juices and spent fluids, seeking solace in post-coital remorse and prayer.
