Innocent and curious, a sister and brother, both amateurs, find solace in each other's company, their shared secrets igniting a forbidden passion. They tentatively explore their bodies, fingers tracing sensitive skin, breaths hitching in unison. The sister's wetness coats her thighs as she rides her brother's hand, her moans stifled against his shoulder. They stumble through awkward firsts, laughter punctuating their intense, taboo love-making. Each touch, each thrust, a whispered promise of more.
