After riding the horses hard for a few hours, the concubines came to a stop in a clearing in the woods. They dismounted.
"There is a village near here," Rosilla said. "We can get supplies and some new clothes with the gold Anya gave us."
"Perhaps some riding gear, too?" Nanette asked. Rosilla nodded. "Good. Should we tie up the horses?"
"No. They are well-behaved and trained. If we tell them to stay, they will." Rosilla turned to Battle and Steel. "Stay here." The horses whinnied their agreement. Once the concubines were gone, Battle looked at Steel. She flicked her tail to one side, exposing her vagina.
"In a bit, my Princess," Steel said. He walked over to a creek. "Let us eat and drink, take a brief break before we get down to business." Battle sighed. Her guard was right.
The horses satiated themselves while they caught their breaths. After half an hour of rest, Battle sidled up to Steel.
"Steel," she whispered. Steel looked at her. "Would you care to...do Battle?" she asked flirtatiously. Steel whinnied in amusement.
"Gladly, my Princess."
Battle moved her tail to one side. Steel went to her back. Battle gasped as she felt his muzzle in her pussy, breathing in the scents of a mare in heat. Then he began to lick. Battle neighed in delight.
"More, more!" she begged. "I want- I need you inside me! I need your cock in me!"
"No need to ask twice," Steel neighed. Battle felt his hooves on her back and closed her eyes, ready. Steel plunged deep within her, rocking back and forth, filling the mare with ecstasy.
"Oh- oh!" Battle neighed. "Is this- is this how my concubines felt?"
"I suspect even better," Steel replied. "You are in heat, after all. Sex will feel more satisfying until you leave heat."
"How long- ooh!" Battle was unable to finish her sentence as Steel came, flooding her with his seed. He continued to pump more and more seed into her, bringing her to orgasm as well.
"Oh!" a voice gasped. Battle opened her eyes. The concubines had returned and were watching the horses mate, shock on their beautiful faces. Battle wanted to break apart from Steel immediately upon being seen, but they were too far into it.
"Let us leave them be," Rosilla said to Nanette. As Steel continued to fill Battle's womb with seed, the concubines got dressed in new, less attention-grabbing clothes and made a lunch. Finally, Steel finished, shooting one last massive load into the former Prince. Battle panted, feeling seed dripping from her pussy down her back legs.
Battle walked over to the concubines. Rosilla patted her neck, smiling.
"That was a better performance than anything I'd ever seen in the Prince's Harem," she joked. "I hope you two got your fill. We need to leave now."
"Already?" Nanette whined. Rosilla nodded.
"Yes. The border is still days away. Any time we can shave off traveling will help us."
"Is riding so hard and fast safe in your condition?" Nanette asked. Battle's ears pricked up. Condition? What condition? Rosilla laughed.
"Dear Nanette. My family is horsemen. Our culture revolves around horses. We traveled with them, riding them in all stages of pregnancy. My own mother birthed me while on a horse galloping through a forest. I will be fine."
Pregnancy?! Battle looked at Steel.
"She is with child?" Battle neighed. The concubines began to get the horses saddled. Steel nodded. "Did you know before?"
"Yes. Anya told me. I suspect that is why they split up. There is more than one of your concubines with child, after all, and having them all travel in one group would be a poor choice. They would all be captured. This way, they have a better chance of at least one heir making it to safety."
Battle stomped the ground, determination surging through her.
"No more fooling around," she vowed. "I must protect my child." Steel nodded in approval, but he knew something Battle did not.
Battle's question had been interrupted before she could finish, but she was wondering how long a mare would stay in heat. Steel knew that a mare would remain in heat until she became pregnant or a spell was cast to end it. Battle had many days of heat ahead of her, and she would not be able to hold off desiring to mate for long.
