In a quiet moment, a brother and sister find themselves alone, the air thick with unspoken tension. The sister, Michelle, starts to touch herself, her moans barely audible. Her brother, catching her mid-act, joins in, his own hand moving slowly over his erect cock. They lock eyes, the taboo of their actions only heightening their arousal. Their parents' voices echo from downstairs, but they can't stop now. Michelle, her pussy dripping, begs her brother to fuck her, to relieve the pent-up desire they've both been feeling.
