This is a damsel-in-distress bondage story set in the world of Game of Thrones: in fact, it's based directly on a canon event during Aegon's Conquest, expanded and slightly massaged to appeal more to DiD fans like me. It's pretty gentle, but don't read if you're offended by bondage and mild humiliation.
With the Storm King dead, slain by the bastard Orys Baratheon during the terrible battle known as the Last Storm, his daughter by rights ascended to the throne as his only true-born heir. If any in Storm's End doubted her claim, they did not choose to say so.
Argella Durrandon had little time for grieving, and little interest in it either. She was truly her father's daughter, quick of temper and stubborn of heart; she had heard tell of the burning of Harrenhal, but cared not. Let the Targaryen whore bring her dragon, she said, and I shall pluck out its eyes. The stormlanders pulled up the drawbridge, manned the battlements with the few soldiers remaining to them, and waited.
As strong-willed as she undoubtedly was, Argella was a mere woman, and no warrior. If Queen Rhaenys had flown Meraxes over the castle's monumental curtain wall, it is most unlikely that its eyes would have been in peril; the outcome would have been bloody, but predictable. Aegon would have been presented with a second smoking ruin to rule over, and his sister-wife's compliments. In the event, however, Storm's End did not fall in this way.
In the evening of the same day, as Argella retired to her chambers, whispers began to circulate. The queen was brave, it was conceded, and the castle impregnable under normal circumstances; yet fine words and thick walls were equally ineffective against dragonfire, as Harren the Black had discovered to his cost. Hunkered down in the largest and strongest castle in the realm, Harren had roasted alive along with his sons and lords bannermen. What, asked the whisperer persuasively, would it profit the house of Durrandon to have its ancient seat reduced to molten rock, and its people to ash?
And so a plan was hatched.
The next morning, the bastard Orys Baratheon sat in his tent, supping wine and giving due consideration to his breakfast, when he was disturbed by a commotion. Stepping out into the watery sunlight to demand an explanation, he was shocked by a sight that neither he, nor any of the men present, would ever forget. They had received a visitor from Storm's End.
