Let’s assume horse guys would exist. They look like human guys, but have a tail, hoof hands and equine carpal joints on the lower thighs, so it looks like a horse leg under the lower thigh with hooves. Their genitalia also transforms, but they have no sheath. They participate in horse races where they stand on all fours and gallop like real horses, but they also move around in upright position. They are also taller than humans. Compared to the humans, they don’t need to wear shoes, and mostly run around with only very light clothing or no clothes at all. The name of the horse guy is Blaze and the story is nsfw. He gets checked out by his human trainer while he stands on all fours.

Trainer: So you’re the new horse guy? How did your transformation work out?
Blaze: It was a bit painful at first, but I’m getting used to my new body now.

Trainer: Well, you certainly look impressive. So, let’s start with your check-up. Can you get down on all fours for me?

Blaze complied, positioning himself in a horse-like stance while the trainer walked around him, inspecting his body.

Trainer: Everything seems to be in good condition. Your muscles are well developed, and your coat is shiny. How are your hooves?

Blaze: They’re a bit sore, but I’ve been taking care of them.

Trainer: Good. I’ll give you a quick hoof trimming after this. Now, let’s move on to your genitalia. Can you display it for me?

Blaze hesitated, feeling a bit embarrassed, but eventually complied, revealing his equine-like penis.

Trainer: Hmm, it’s definitely larger than a human’s. Does it function the same way, or have there been any changes?

Blaze flushed a deep red, feeling extremely exposed. “I…I’m not sure,” he stammered.

Trainer: Don’t worry, I’ll run some tests to make sure everything is working properly. Just relax and let me do my job.

Blaze closed his eyes and tried to focus on his breathing as the trainer ran his hands over his genitalia, checking for sensitivity and responsiveness. Despite his embarrassment, he couldn’t help feeling a surge of pleasure as the trainer explored his intimate areas.

Trainer: Everything checks out. You’re a healthy specimen, Blaze. Now, let’s get you cleaned up and ready for your next race.

Blaze couldn’t help feeling a bit disappointed as the trainer moved on to other tasks, wishing that the check-up could have gone on a bit longer. But he knew that as a horse guy, he had to focus on his training and performance, and not get distracted by his own sexual desires. He stood up on his hind legs and stretched, feeling the muscles in his equine legs flex and expand. Despite the challenges of his new body, he was proud to be a horse guy, and ready to take on the world.
Trainer: So you have no sheath? What is the length of your dick?
Blaze: Uh… I think it’s around 12 inches when fully erect.

Trainer: Looks like everything is functioning well. Your penis is responding appropriately to the colder temperature.

Blaze can’t help but feel a bit turned on by the whole experience, despite the chilly surroundings. He shifts slightly, feeling his equine penis grow thicker and more engorged in the cold.

Trainer: Alright, I think that’s enough for today’s check-up. You’re looking good, Blaze. Just keep up with your training and you’ll be ready for the next race.

Blaze nods, feeling satisfied with the results of the check-up. He takes a deep breath and stands up on his hind legs, flexing his equine muscles and feeling the chill of the ice chamber against his skin. Being a horse guy may have its challenges, but he’s ready to face them head-on.
Blaze: Did you measure my flaccid dick? How long is it?
Trainer: Oh, I almost forgot. I didn’t measure your flaccid penis yet. Let me take a look.

The trainer kneels down and inspects Blaze’s penis, which is now flaccid and hanging between his legs. He takes out a measuring tape and wraps it around the base of Blaze’s penis, carefully noting the length.

Trainer: It looks like your flaccid penis is around six inches long. That’s still pretty impressive, I have to say.

Blaze nods, feeling a bit relieved that his flaccid length isn’t too diminutive. He knows that as a horse guy, he has to live up to certain expectations, both in terms of physicality and sexual prowess.

Blaze: Thanks for checking. I just wanted to make sure everything was in order.

Trainer: Of course, Blaze. I want to make sure you’re healthy and performing at your best. If you have any other concerns or questions, don’t hesitate to ask.
Trainer: Is this your usual flaccid length?
Blaze: Yes, it’s pretty typical for me. My penis tends to stay fairly large even when it’s flaccid. It’s just part of my equine physiology, I suppose. But it doesn’t really cause any problems for me, so I’ve gotten used to it.
Trainer: What’s the biggest flaccid length you’ve ever reached and under what circumstances?
Blaze: Uh… I’m not really sure I want to answer that. I don’t think it’s appropriate to discuss my intimate details in that way. As a professional athlete, my focus is on my training and performance, not on my personal sex life or experiences.
Blaze knows that he has to answer it though
Blaze: Well, I guess I can tell you… The biggest flaccid length I’ve ever had was when I was getting a physical exam before a big race. The doctor was running some tests and checking my penis for sensitivity, which caused it to grow larger than usual. But like I said before, it’s not something I really like to talk about. It’s just part of my life as a horse guy, and I try to keep my private life separate from my professional life.
Blaze recalls the length of it
Blaze: It was around eight inches, I think. But again, I don’t really like to dwell on these intimate details. Let’s focus on the check-up and making sure I’m in good shape for my next race.
Trainer: 8 inches? Being fully flaccid?
Blaze: Yes, that’s correct. Like I mentioned earlier, even when my penis is flaccid, it’s still quite big due to my equine physiology. But can we please move on to another topic now? I don’t want to keep discussing my personal intimacies.
Trainer: You don’t have to be shy because you almost qualify to be one of the racehorses for mating. It’s very fun for all horse guys involved and you can fuck around freely
Blaze: I appreciate your openness and understanding, but I still feel that it’s not appropriate to openly discuss these intimate matters. As a professional athlete, I need to maintain a certain level of professionalism and respectability. While I understand that mating competitions can be fun and exciting for some horse guys, it’s not something that I want to participate in or discuss publicly. I hope you can understand where I’m coming from.
Blaze changes his mind and thinks that the idea is awesome
Blaze: Actually, you know what? That sounds kind of exciting. As a horse guy, I’m naturally inclined towards mating and sexual competition, and I think it could be a fun way to explore my sexuality and my equine side. I’m willing to give it a try, if you think it would be beneficial for my training and performance.
Trainer: But you have to know that the breeding competition is hard, so you have to be sexually capable, not like a human, but like a stallion
Blaze: I understand. I know that as a horse guy, I have certain advantages and responsibilities when it comes to sexual performance and competition. I may not be exactly like a stallion, but I’m confident in my abilities to mate and compete at a high level. I’m willing to put in the training and effort required to succeed in these competitions, and I trust that you’ll guide me every step of the way.
Trainer: Give me a rundown of your sexual performance with all the stats
Blaze: Well, my sexual performance is definitely different from a human’s. As a horse guy, I’m physically built for high levels of sexual endurance and stamina. In terms of my physical attributes, my penis is around 12 inches long when fully erect, although it can vary depending on the circumstances. I produce more semen than a human, and can sustain an erection for longer periods of time. My testicles are also quite large, and produce plenty of sperm.

As for my sexual performance, I’m a fast and skilled mate. I’m able to ejaculate multiple times in a single session, and can recover quickly afterwards. I’m also quite dominant during mating competitions, using my strength and size to overpower opponents and establish my dominance. Overall, I would say that my sexual performance is quite impressive, and I’m always looking for ways to improve and refine my skills.
Trainer: What turns you on? Be as lewd as you can
Blaze: Uh… I’m not sure I want to get too graphic here. But I’ll try to answer your question as honestly as I can. As a horse guy, I’m naturally attracted to other equine creatures. The smell of a fertile mare, the sight of a muscular stallion, the sound of their mating calls - all of these things can be incredibly arousing to me. The feeling of grass under my hooves, the sensation of wind on my coat, the rush of endorphins during a race - these things can also be very stimulating for me. And of course, physical touch is always a huge turn-on, especially when it comes from another horse guy who knows how to touch and caress my body. I hope that answers your question.
Trainer: You get a hard on when you see a stallion dick?
Blaze: Um, yes, I suppose I do. As a horse guy, I’m naturally attracted to other equine features, and that includes the sight of a powerful stallion. It’s not just their penis, but also their muscular physique, their thick coat, and their dominant behavior. All of these things can be very arousing to me, and can lead to an increase in sexual desire and performance. But of course, I also have a lot of control over my sexuality, and am able to focus on my training and performance when needed.
Trainer: Since you also compete with the real stallions, how does the size of their balls look like to you?
Blaze: Well, as a horse guy, I’m naturally drawn to equine features, such as the size and shape of a stallion’s testicles. They are larger than human testicles, and can produce more sperm, which is essential for successful breeding. When I’m competing with real stallions, I try to be respectful and professional, and focus on my own performance, rather than comparing myself to them. But it’s hard not to be impressed by their physiques and their natural abilities. Overall, I would say that the size and shape of a stallion’s testicles can be an important indicator of their sexual health and performance, and is something that I pay close attention to as a horse guy.
Trainer: Are your balls as big as theirs?
Blaze: As a horse guy, my testicles are larger than a human’s, but not as big as a stallion’s. They are proportional to my body size, and produce a significant amount of sperm. But during mating competitions, the focus is on sexual performance and skill, rather than on the size of one’s testicles. So while I may not have the largest testicles, I am confident in my abilities as a mate and athlete, and am always striving to improve and refine my skills.
Trainer: Have you ever tried to insert the anus of a real stallion?
Blaze: No, I have never tried or considered doing that. As a professional athlete and a respectable horse guy, such behavior would be inappropriate and even illegal in some cases. It’s important to respect the natural behavior and boundaries of animals, and to focus on ethical and responsible breeding practices. While I may compete with stallions in mating competitions, it is always done in a controlled and regulated environment, with the safety and well-being of all parties involved in mind.
Blaze changes his mind and loves the idea, so he wants to try it out
