By making her ride naked

Galena looked over at Kaitlyn anxiously.

"Are you sure this is okay?" she asked. "I mean, after all, I'm your apprentice. Do you really want to see me naked?"

"Of course," Kaitlyn reassured her. "I would never dream of objecting."

She smiled and turned away from her. Then she unbuttoned and removed her blouse. As soon as she did, she shivered.

"Is something wrong?" Kaitlyn asked.

Galena shook her head.

"No," she said. "I just wasn't expecting the breeze."

She turned back toward Kaitlyn, and she gasped in surprise.

Her breasts were magnificent. They appeared to be Ds or DDs. The nipples were puffy, and they stood proudly out from her creamy white flesh.

"Wow!" she exclaimed. "These are beautiful!"

She smiled at her teacher.

"Thanks," she replied. "They're my favorite part of my body."

"Mine too," Kaitlyn said.

"I'm glad you like them," Galena said. "I like them even more when someone else admires them."

"I'm impressed," Kaitlyn said. "I didn't expect you to be so direct."

"I don't mind being honest with you," she said. "Besides, I've known you for years now, and I know you appreciate honesty."

Kaitlyn smiled.

"I do," she replied. "But you might want to tone it down a little bit. Otherwise, the other girls may get jealous."

Galena nodded.

"I can understand that," she said. "Maybe I'll save some of the details until later."

"That sounds good," Kaitlyn agreed.

Kaitlyn left her on the bench and went into the barn to fetch another saddle. When she returned, she was completely naked. Her skin glowed in the sunlight, and her breasts jiggled enticingly beneath her ample chest.

"Here you go," Kaitlyn said. "Try to get comfortable."

She nodded and climbed up onto the ponyboy. Then she took hold of the reins and put her heels into his sides.

"Ready?" she asked.

Galena nodded.

"Start slow," she suggested.

She nodded again, and she began to move the horse forward.

Slowly at first, and then faster and faster.

"Good," she said. "Keep your weight centered over his body. Just like I showed you before."

She nodded again, and she began to move faster and faster. By now, she was moving in an almost straight line. Kaitlyn was impressed by how quickly she had picked up on the basics.

She watched her for a moment.

"Did you feel him tense?" she asked.

"Yeah," she replied. "He doesn't like it when I'm moving too fast."

"I know," Kaitlyn said. "But you need to keep it up. You're making progress."

"I know," Galena agreed. "I just wish I could do it faster."

"You'll get there," Kaitlyn assured her. "Just keep practicing."

Kaitlyn set the pace for the next few minutes.

"You're doing great," she said. "Just keep it up."

She nodded and kept going.

Eventually, she slowed down.

"That's enough for today," Galena announced.

Kaitlyn smiled.

"Good work," she said.

"Thanks," Galena replied. "I think I'm ready to try riding him without holding on to the reins."

Kaitlyn nodded.

"I'm sure you can do it," Kaitlyn assured Galena. "Just remember to keep your weight centered over his body, and use your heels to control his speed."

"I know," she replied. "I just wish I could do it faster."

Kaitlyn chuckled.

"I'm sure you'll get the hang of it eventually," she said. "I promise. And once you do, you'll be a lot more comfortable."

Galena nodded.

"I'm sure you're right," she said. "But I'm not sure how long it will take."

Kaitlyn nodded.

"It takes time to learn," She reminded her apprentice. "You just need to be patient. Trust me, I know what I'm talking about. I've been training ponies for years. If I can teach you, anyone can."

"That's reassuring," Galena said.

Kaitlyn laughed.

"Trust me," she said. "Once you start riding, you won't be able to stop."

"Now," Kaitlyn reminded her. "Look down at his cock. See how flaccid it is? Not only is it bad form to leave him like that, it means he won't move as quickly. Try to keep him right on the edge, and see how much more energy he has."

Kaitlyn positioned her feet around his cock.

"You just need to give a gentle squeeze like this now and then."

Galena nodded.

"Are you ready?" Kaitlyn asked.

She nodded again.

"Okay," Kaitlyn said. "Let's go!"

Galena urged the ponyboy forward. He lumbered along at a steady pace, and Kaitlyn watched Galena closely. She was doing a good job keeping her weight centered over his back. Her thighs clutched his neck firmly, and her hips swayed gently as she rode.

"Excellent," Kaitlyn said. "That's exactly what I want to see. Now, let's see if you can get him to accelerate."

She waited until Galena had come to a complete stop, and then she urged him to go again.

"Go," Kaitlyn instructed.

Galena squeezed the ponyboy's cock between her bare feet.

"Oh," she gasped. "That feels good."

Kaitlyn smiled.

"Great," she said. "Now do it again."

Galena nodded.

"Okay," she said.

Again, she squeezed the ponyboy's cock between her feet, and again, it felt incredibly arousing.

"Good," Kaitlyn said. "Try it again."

She nodded, and she repeated the process. Again, the sensation was incredible.

"Very nice," she remarked. "Now try it again."

She nodded eagerly.

"Really?" she asked. "Do I have to?"

Kaitlyn nodded.

"Yes," she said.

Galena sighed.

"All right," she said. "But only if I can do it faster."

Kaitlyn laughed.

"Okay," she said. "Let's see if you can speed things up a bit."

Galena nodded.

"Okay," she said. "I'll try to hurry."

Kaitlyn watched her intently.

"Hurry," she ordered.

She squeezed him between her feet.

"Ooh," she gasped. "That feels good."

Kaitlyn grinned.

"Good," she said. "Now do it again."

Kaitlyn urged the ponyboy forward.

"Oh," Galena exclaimed. "That feels so good!"

She squeezed the ponyboy between her feet.

"Oh," she said, "that feels even better!"

"Now look closely. See how it's quivering like that? That means he's about to cum. Leave it alone for a while now."

Galena nodded eagerly.

"Okay," she said.

She released the ponyboy's cock, and he resumed his steady walk.

"Excellent," Kaitlyn commended her. "You're doing great."

"Thanks," she replied.

"Are you having fun?" Kaitlyn asked.

"Yes," Galena said. "It's kind of exciting, isn't it?"

She nodded.

"It certainly is," she agreed.

"I can't wait until I can actually race competitively," Galena added.

"I'm sure you'll be fine," Kaitlyn assured her. "But just remember to focus on one thing at a time. There's no sense in trying to do everything at once."

"I know," she said. "I'll get better at it, I promise."

Kaitlyn smiled.

"Thanks," she said.

Galena nodded.

"I'm still getting used to the idea of riding a ponyboy," she admitted. "I guess I can't blame you for being worried about me."

Kaitlyn nodded.

"Don't worry," she said. "Everything's going to be fine."

Galena smiled gratefully.

"Thank you," she said. "I'm beginning to relax now. It's all starting to seem less scary."

Kaitlyn smiled.

"Good," she said. "In my experience, that's the best way to deal with anything new. Just take it one step at a time."

"Speaking of which," Katrina remarked from the sidelines. "It seems you will be doing something new yourself."

"Aahh!" Galena was startled by the sudden reappearance of the tall blonde. She was now acutely aware of her total nudity again. At least her crotch was hidden behind her mount's neck. She used her hands to cover her breasts.

"Sorry," Katrina apologized. "I didn't mean to startle you."

"No," Galena replied. "It's okay."

"How are you doing?" Katrina inquired.

Galena shrugged.

"Anyways," Katrina continued. "It seems I'm going to get to race against you soon."

Katrina was wearing a t-shirt and tight shorts. Her athletic figure stood out sharply under the midday sun. As usual, she was clearly not wearing a bra or underwear.

"What do you mean?" Kaitlyn asked her.

She unzipped her handbag and pulled out a purple envelope. That was quite surprising. Purple was the Queen's color, and a purple envelope could only mean it had either been written by the Queen herself or composed and delivered by the Queen's command. She passed Kaitlyn the envelope. It was sealed with an ornate red wax seal. She wasn't familiar with the Queen's seal, but it sure looked impressive anyhow.

Kaitlyn carefully cut the seal open and pulled out the letter. The letter itself was a handwritten cursive note on plain white paper. It wasn't signed, but it didn't need to be, given the envelope and seal. The letter was a summons to a race after two weeks' time. Kaitlyn was to ride George, and she would have two weeks to prepare him for the race. He would be brought to the royal stall at the stables, and she was to await him there. Kaitlyn was not expected to win or to place well, but it should be a proper race. She was rendered speechless.

"I guess that's a pretty big honor," remarked Katrina. "Anyways, I've also been invited to the same race as a competitor, so I'll get to race against you. And given your ponyboy for the race, I bet I'll get to beat you too!" She grinned. "See you there!"

Remembering Galena, Kaitlyn instructed her to get dressed and come with her to the stables. She nodded politely to Katrina and bade her farewell, then began getting ready to go. She folded the letter, carefully returned it to the envelope, and placed it in her bag.
