Pregnant With Dragon King's Eggs

Callie signs up for a secret royal surrogacy program mainly for the payment, but when she gives birth to two glowing dragon eggs she panics and deceives King Adrian. Now she scrubs floors inside the palace while concealing hatchlings that can shift into human children, and they call her the king's child. Adrian seems to know far more than he lets on, and his reasons trace back to a night three years earlier, when a young woman on a cliffside tended a hurt black dragon's wing.
