Siblings' Secret Shame

With their parents' voices echoing from downstairs, two siblings, bound by blood and religious upbringing, find themselves alone in the house. The brother, a strapping young man, feels his cock stir as he looks at his sister, her body ripe and ready. She notices, her cheeks flushing, and turns away, but the brother follows, cornering her in her room. "We shouldn't," she whispers, but her words are drowned out by the pounding of their hearts as he presses against her, his cock grinding against her ass.
