Blonde and innocent, Mormon teen Sarah finds herself in a forbidden world when she stumbles upon her sister's secret toy collection. With her sister's guidance, she explores her body, her fingers and toys replacing her hymn book. As her sister teaches her the art of pleasure, Sarah's hunger grows, leading to their first intimate encounter. Missionary positions give way to taboo desires, their religious upbringing forgotten as they indulge in their secret, sacred passion, their moans echoing through the house, a symphony of sinful release.
