No, she fails miserably (Possessed body route)

Lunnara closed her eyes and remembered, she remembered every time than some other woman, some queen or hag, had humiliated her, just like Eilatra and the other matriarchs did all those centuries ago in the underdark. That memory gave her the resolution she needed and she decided she wasn't going to loose, not again, not to this whore.

"NO" She said telepathically to Nameria as she continued to ride the dragon's cock.

"No?"

"This is not you possessing me, this is me forcing you to learn your place, you stupid corpse cow"

"Said that again, you slut."

Then she made her move. She liberated all that power that she had been accumulating through the dragon's cum. It was a bestial amount, far greater of what Lunnara had ever held or concived, she attacked the spirit's defences with all of her strength, all of her determination, and for a moment she thought herself a victor...

But it was all in vain.

Nameria had been ready for such an attack, she had been waiting. Once Lunnara unleashed her **** attack, all of her magical defences were left ****, a rookie mistake, one that the old spirit of the queen was keen to notice. She did not hesitated to punish that mistake, nor did she show any mercy. The dark elf sorceress tried to move her hands to begging a new spell, a new **** attack, but she realised in horror that she could not move those hands anymore...

Because they were no longer hers.

"That was cute, elvish whore. But cuteness is not enough to claim the dragon... You need REAL beauty for that." Just then, the sorceress tried to scream in horror, maybe in a show of rage, maybe to plead, but her own lips no longer obeyed her.

"Now, your ass is mine." The spirit made her own hand slap her booty, mocking her less voluptuous frame.

"Now, your cunt is mine." Nameria made the elf's body jump on the dragon's cock harder, to be really impaled, a long deserved prize for her sounded victory.

"I am yours... MY LORD." She said out-loud, using her new and usurped vocal cords, riding the dragon's dick with renown vigor.

"AS I HAVE ALWAYS BEEN."

Just as she spoke, the dragon blessed their interiors with his cum, and Lunnara's consciousness flowed and faded far away from the material realm of her own body.
