Leks merely snorted at Iris and walked away. Iris, still playing the role of a good submissive, claimed mare, didn't follow. But Leks knew her claiming was incomplete. It would only be complete, making her fully under his control permanently, if he impregnated her. Yes, there was the issue of him wishing to return to his human form eventually, but he had a feeling Iris would make a fine wife, and the claiming would stick once she was turned human.
In order to impregnate Iris, she needed to give birth. Luckily, Ladybug, who was still thoroughly under his metaphorical thumb, could fix that.
Leks walked up to Ladybug. Ladybug nuzzled him sweetly.
"Yes, my alpha?" she asked. Leks nuzzled her back.
"Iris is being stubborn. To keep her, I must fully claim her." Leks met Ladybug's eyes. "You know what you must do." Ladybug bobbed her head.
"Yes, my alpha," she said. She fixed her gaze on Iris, who was grazing some distance away. Iris let out a whinny of shock. Her sides swelled. Within a matter of minutes, she was laying on the ground, neighing in distress as she pushed out her foal. Ladybug and Leks trotted over.
"A fine colt," Ladybug remarked upon seeing the pure white foal. Iris looked at Ladybug. Her eyes widened, then narrowed.
"You!" she whinnied furiously. She got to her hooves. Before she could do anything, however, her foal got up and began to nurse from her. Iris turned her attention to the colt, licking him clean.
Ladybug turned to Leks.
"I have prepared her body again. Whenever you are ready, my alpha."
"Once her foal is satisfied," Leks said softly. "I am no savage."
After a few minutes, the foal finished nursing and wandered off. Leks surged towards Iris. But she was prepared for him. He had underestimated her. The moment she felt his hooves on her back, she spoke the magic phrase.
"Protect me!"
