"Yes, you may stay," Olga said. She closed her eyes. "But given your virility and your family's magical abilities, your seed cannot go to waste."
"What do you mean?" Mikhail asked. Olga grimaced.
"If you wish to stay, you must first impregnate every Horse Witch that came with me, including myself." Mikhail's jaw dropped. He didn't have to look at Nightingale to know she would be making the same expression.
"What? Why?"
"I told you. Your family is exceptionally powerful. The King wishes for that power to be present in Horse Witches produced by his loyal followers." Olga lowered her head. "I apologize in advance."
"If that is what I must do to stay, so be it," Mikhail said firmly. Olga nodded.
"Come with me." Mikhail followed Olga to the breeding barn. All the Horse Witches that had come with Olga were waiting already, grim looks upon their faces. "I will go first," Olga said. She took a mare's form. Mikhail took his own stallion form. He mounted Olga, determined to not enjoy himself. Soon, whinnies filled the barn.
Halfway through the company of Horse Witches, Mikhail felt himself beginning to slow. Olga, pregnant with identical triplets, cast a revitalization spell upon him so he could continue.
A few hours after he started, Mikhail was finished. Every single Horse Witch was now a mare pregnant with twins or triplets. He quickly returned to human form and collapsed to the ground, exhausted. Hands helped him to his feet. He looked up. It was Nightingale, the babes strapped to her back.
"Thank you for your contribution," Olga said softly. "The King is glad you have helped us with the next generation of Horse Witches. We will be in touch."
The Horse Witches gathered outside and, as one herd, galloped away. Mikhail watched them leave.
"Hopefully they do not request me as a stud again," he said, panting. Nightingale smiled.
"I am sure your days of being a stud are over. Now, let us go inside to tell Lord and Lady Copperstone all that has transpired today."
