Johnny and Beth were rather typical teens. Johnny was 19, standing 5 foot 10 and weighing 150 pounds. Johnny was clever with his hands and could often be found making things out of stuff that could be found on the sprawling farm. Not that their parents were farmers, it was just that they loved country living. They rented out the farm lands to a neighbor. But the place had a few buildings including an old barn where the kids could often be found playing while growing up.
Beth was 18 and tall for her age at 5 foot 7, weighing 110 pounds. She had tits that had just begun to fill a B cup bra. She had always had a thing for horses and bugged her parents about getting one. She still had her collection of My Little Pony's from when she was much younger, occasionally playing with them to this day. She'd read every book in the library that dealt with horses with Misty of Chincoteague still being her favorite. It was her fascination with horses that led to this story.
Both parents worked in the city and so the kids were left to their own devices during the day. School had just let out for the summer and already both kids were bored. One problem with country living was that all their friends lived too far away for them to get together without some complicated arrangements, especially since most of them didn't have a car and the ones that did usually worked full time in the summer.
"Johnny, I am so bored. I just wish we had a horse. I would love to spend the day riding. We have all this land around us, I could ride all day and not see a single person."
"You know our parents aren't going to let you get a horse. Maybe you should just pretend you are a horse. You are a little horse face, you know."
"Johnny, that is so mean! I do not have a horse face. Now, take it back!"
"Oh, all right. You don't have a horse face. Better?"
Mollified, Beth just huffed and walked away. But one thing did stick in her mind, his suggestion that she play at being a horse. So, for the next couple of hours, she pranced around the yard pretending she was a horse. Johnny was so bored that he watched her for a while before wandering off to the barn.
The next morning found him back in the barn, making something. "Johnny, what are you doing? Why don't you come play with me? Come on, I'm bored."
"Not now, I'm busy."
"What are you doing? Can I help?"
"No! I want this to be a surprise. So, stay out!"
Whatever he was doing took him a couple of days. Beth was curious and tried to snoop but he kept himself locked in a small room in the barn and she couldn't get a peek. Finally, he was done and called out to her.
"Beth, come here. I have a surprise for you." When she came into the barn, he placed his hands over her eyes and led her over to the open door of the room where he'd been busy for the last few days.
"Ta da!"
Beth took a second to process what she was seeing. It was a mannequin draped with leather bands. Then she realized what it was, a harness much like a horse is adorned with but this was for a person. There was even a headdress that look like a bridle.
"Johnny, is this for me!? Oh, I can be horse for real. Can you put it on me now? Oh, this is so exciting."
"Sure. But you're going to have to change out of that dress. A couple of the straps go between your legs."
"Okay. I will be right back."
"Make sure whatever you wear fits you pretty tight. Otherwise putting the straps on will be a pain."
Beth was back 5 minutes later wearing an old t shirt and shorts that she had almost outgrown, so were tight.
"Okay, stand there. This might take a while. I have to tighten all the straps so they fit you. The mannequin is for a bigger person."
"Okay. Just put them on." By this time, she was quivering with excitement and could barely hold still.
It took about 30 minutes until Johnny was satisfied that the harness fit. Then he started on the bridle. It didn't have a bit but still took some jiggering until it fit well enough that it wouldn't fall off. During all of this, Johnny's hands roamed over her body. Neither of them really noticed. Beth because she was so excited. Johnny because he was engrossed in figuring out how to make the harness work.
"There, that should do it. Why don't you run around the barn a little to make sure if it fits right."
He had barely gotten the words out when Beth took off, running around the barn before coming back to stop in front of him. "I think it needs little tightening here" Pointing to a strap that ran across her chest. "And it needs to be loosened here." Pointing to one of the straps that crossed her crotch.
Johnny made the necessary adjustments and she took off again. She ran around for an hour before she found him again. "Johnny, this isn't right. Horses don't just run around free with their tack on. I want you to train me."
"Train you! What do you mean?"
"I want you to get a long lead and have me run around you. You can train me to do high steps and stuff."
"I don't know. Doesn't sound that fun to me."
"What else do you have to do? Come on, it will be fun. Tell you what, you can make a long whip and use it on me, just like a real horse trainer. You know the kind they use. Like a real long stick with a little whip on the end. It isn't meant to hurt, just get the horse to do things."
