Aphrodisiac wine

From a scene from Bound by Wyvern’s Blood where Mirrin doses Brendar’s wine with an aphrodisiac:

He drained the glass, then set it down on the table and smiled when he saw how intently she was watching him. “The wine was still trembling in its glass when you finished with it,” he said. “Careless of you. Was it poison? I switched glasses.”

She swallowed. Her mouth was dry. Blindly, she reached for her own wineglass and almost knocked it over. Some of it spilled onto her dress, leaving a crimson stain. It didn’t matter; she’d be undressing soon enough. “It wasn’t poison.” She brought the glass to her lips.

His eyes widened as she drank. It ran like molten metal down her throat. She never released his gaze, even as she lowered the glass.

Her voice grew husky. “And I put it in both our glasses.”

His chair crashed to the floor behind him as he rose and leaned over the table. “What was in that wine?”

His words were a low growl.

The air seemed overly warm. She tugged at the neck of her gown. There was no reason not to answer; he’d already drunk. “The heart’s blood of a wyvern. It inspires lust.”

“Do you know what you’ve done?” he demanded. Sweat shone on his forehead.

“Your father slew the wyvern,” she said. “The blood was rightfully yours. And you captured Elenyor. You’ve one last thing to take, Warlord.” She began to pull at the laces of her bodice.
