In the dim light of their shared room, a brother and sister, both curious and inexperienced, tentatively explore each other's bodies. The sister, her heart pounding, guides her brother's hand to her breast, gasping as he tentatively squeezes. He, in turn, feels a surge of desire as she wraps her hand around his hardening cock. Their first time together is a clumsy, innocent dance of discovery, their bodies entwined, their moans soft and uncertain. They mark the occasion with a shared orgasm, their bodies shuddering together in a taboo embrace.
