Hidden away in their shared room, the siblings exchange stolen glances and hesitant smiles, their hearts pounding with a mix of fear and excitement. "Thicky nicky" indeed, they think, as they tentatively remove each other's clothing, revealing smooth, unblemished skin. Their first touches are light, exploratory, their breaths hitching as they discover the softness of breasts, the hardness of untouched cocks. They take their time, learning each other's bodies, their inexperience making each touch both tentative and electric. As they grow bolder, their kisses deepen, their touches become more insistent, and their bodies press together, seeking satisfaction in this forbidden dance.
