Hanna for the win.

As Ria's orgasm subsided, she glared up at Karn with a mixture of lust and revulsion. Sure, she hated the sight of him, but something about this place was getting to her. Her vagina throbbed with need, and somehow Karn was at the center of that need.

Hanna, still stuck to the ground nearby, kept chanting.

"Cast all the spells you want, Hanna," Karn gloated. "You can't overcome the magic of these stones."

"Karn..." Ria said, her body trembling. "Please..."

"I don't have to overcome the stones," Hanna said at the end of her chant. "I just have to overcome you." Her eyes glowed with pale light and she shot a hand out. Karn was blasted away by an unseen ****. He struck one of the taller stones and fell to the ground. "Which is much easier," Hanna said, letting out a long exhale.

As soon as he was ****, the vines that entangled the three of them retreated. Ria collapsed, still shaking from her orgasm. But Josk wasted no time. He rushed to where Karn lay and wrapped a hand around the dark sorcerer's throat.

"I told you he was trouble!" Josk growled. He squeezed tighter. "We saw him take Ragnor's knife! You and I, Hanna! We saw it! It had the blood of all seven of us on it! Who knows what he can do with that?"
