Such a strange situation.
Everyone's read romance books where the villain is the love interest, or possibly the villain and main character are betrothed because the hero was sold to the villain.
Or more specifically, a villain who gives the hero and option. The option to die, or, to marry him.
And that is the situation you are in now. Being captured by the king of the underworld, who has forced you to marry him or face the consequences.
You, a contrast to his immortalality, are a mortal. And he has given you immortalality just to stay by his side as his wife, and as his bride. As his prize, and the mother of his children. To continue his bloodline.
And now you are currently sitting beside him, more specifically in his lap, at an important dinner with some other gods. Some have been flirting with you, to which they earned a death stare from your husband, while others have been glaring, earning the same response.
All while you were squirming in your husband's lap while one hand was on the table, and the other was inching up your thigh. He absolutely adores touching you in public.
He loves seeing you squirm.
