"Is it like when he tries to climb on to another horse, and then finds he can't, so he drops off and his penis disappears again?" the enquiring mind of the little girl was trying to sort out the differences and similarities between the two ideas. It was not easy. "Yes a bit like that." Another idea filled Lorena's mind as she assimilated the new information.

"Will you have a baby? Every time Texcoco tries to get on top of another horse the other horse has a foal. Will you have a foal?"

"No, I will not have a foal. A human can not give birth to a horse, only a horse can do that."

"How long will you stay like that? Is Texcoco finished yet?" Came the next question from the little girls inquiring mind. Each question was answered with patience and understanding though the answers were not always as complete as Lorena would have liked. However she gleaned a large quantity of information. As she talked to the maid she took the opportunity to get close to the coupling and study it closely. She sat in the straw at the horse's feet and lifting her night dress over her head she started to do a comparison of their two pussies. Her own was much smaller and there appeared to be several things missing. There was no thin fleshy bits, but she had seen that earlier.

Now she noticed that the little triangle of flesh with the sticking out pointy bit, at the top of the maid's vagina, was also missing on herself. She could also see that the maid had a small hole just above the place where the horse's penis went in. Questions were asked about all these things. Then the horse moved again.

The maid rocked in the harness as the large penis momentarily penetrated deeper. A creamy white jelly like liquid oozed out of the maids vagina and stuck to her buttocks and anus. Another question. When she was told to leave because it was nearly dawn, she did not resent the instruction. She left quietly and ran to her room, leaving the maid much relieved, hanging in her harness, stretched by the mass of horse flesh that entered her tender loins. The horse did not mind and just kept on eating.

Time passed and Lorena had to be satisfied with the information that she had got so far. There were no chances presented to her where she could build on that start. It was spring again before a new situation showed its head. The young girl that Lorena had seen riding under a horse the previous year, showed up again. It had been a pleasant sunny morning and Lorena had been having her daily horse ride in the fields around the hacienda. The local workers were out in force looking after the fields of coffee plants and cocoa.

The ride had taken a little longer than had been expected and Lorena was late for her tuition. She had ridden quickly into the yard and dismounted, then without a thought she had walked her horse into the stables. As she had passed along the stalls looking for a free space she had seen a horse she did nor recognise, in one of the stalls. It was rigged with the now familiar harness. She found a free stall and lead her horse in. Then with a quick word to the stable boy to groom and water the horse she left to look at the newly rigged horse. It was not one of their horses, she did not remember seeing the beast before, until the girl walked into the stables. She was wrapped in a blanket and had nothing on her feet. She stopped dead in her tracks when she saw Lorena. She started to turn and leave.

Lorena had to think fast. Her tuition went out the window as she softly said. "Please don't go, I would like to help you if you will let me." The girl looked back, hesitating before she fled. Lorena was encouraged by the girl's delay, and continued. "I know how to do up the straps and I promise not to do them too tight." Lorena had seen them done once, at close quarters, and the fact that the other girl was at least ten years older did not worry her at all. The girl turned toward her.

"If you help me in will you lead me as well?" Lorena beamed with delight at the invite and all other plans evaporated into nothing. "Of course I will, I would love to do this for you. I want to do the same as you when I am grown." It was then that the idea that she wanted to be a belly rider gelled in her mind. It was to become her one burning ambition and take her further than this bigger girl would ever dream of going.

The girl started toward Lorena. So she had made a substantial decision and now she realised that it had been her ambition to ride like this since she had had the chat with Titsilini all those months before. Lorena turned and walked into the stall that contained the horse. She went to the head of the horse and took the bridle. The other girl came in behind her. "What's your name?" She asked, as she removed the blanket that had covered her so far. Lorena looked up at the girl to answer. She was looking at a totally naked girl who was quite attractive and slim. Firm round breasts flat tummy and bald pussy. Lorena hesitated in her reply. The girl looked at her questioningly, there was a smug expression on the girl's face.

"Is anything wrong?" Lorena was prompted into a response. "No everything is fine, I was just thinking I would like to look like you when I am grown. You are so slim and beautiful." There was another short silence. "My name is Lorena, my Father owns this land." The other girl's mouth dropped open in surprise. "Your Father is Don Albert La Ruse Dell Fuego?" she dropped to her knees and clenching her hands in front of her chest as though in prayer.

"Please forgive me I would never have spoken to you in that manner if I had known that you were the daughter of...."

"It is all right, you were not to know who I was just as I do not know who you are. I hope this will not spoil our friendship. I do want to help you or I would not have asked. Please get up and tell me your name." Lorena smiled at the girl and offered her a hand. It was taken tentatively and the young lady stood. Her head hung as though in shame. Lorena tried to bring her round.

"As long as we can keep it so, I would like you to forget that I am my father's daughter, and just pretend that I am another working girl. I am sure that we can get along well together but I fear that the adults will try to keep us apart. Lets hope they take their time about it, you can call me Lora. Now you still have not told me your name so unless you do I shall have to call you Girl, or Rider or just Hay You. Do you have a preference?" The girl looked up at Lorena and seeing that she was smiling, smiled back.

"My name is Neltitaca Xaltocan." She looked at Lorena wondering if the connection would be made between herself and her cousin Titsilini. Evidently not, so she announced the relationship. Lorena nodded understandingly and then asked a question that made a different connection.

"Is that why you both like to ride under horses, because of your family connection?"

"There is a connection in that we both have the same tutor, but we ride for different reasons. Titsilini started riding because she likes horses, my reason is more personal and I would rather not say yet, if you don't mind. However I do enjoy riding like this." Just then there was a cough at the door of the stables and an elderly woman walked in. She must have been fifty and walked with a very bad limp, using two sticks to support her frail body. "Come on..." there was a hesitance. Then she continued. "Hhummm, Titaca, climb into the harness. You should not keep an old lady waiting."

There was an element of irritation in the old woman's voice. "Are, you have found a new person to help, have you, well that is fine with me. It means that I can go back to my nice chair and rest my legs. Come here girl and I will show you what to do now." Lorena recognised the unfriendly nick name that had been made from the older girl's proper name.

Neltitaca got down on her hands and knees and then slowly and carefully climbed into the harness. Again the manoeuvre was made by going in face down and then turning over to lie on her back before being strapped in. Lorena watched carefully, she would do this one day. When the girl was in, Lorena went to the old lady and crouched down to watch what she did. The old lady produced a small tube with a needle in the end. The tube contained a blue green liquid. She gave the contraption to Lorena.

"You may as well learn right from the start so do exactly as I say. If you do not you may kill the horse so be very sure to listen and remember." There seemed to be no concern for the girl underneath, who would be crushed if the horse collapsed and died. "First point the syringe up with the needle at the top." Lorena did as she was told. Horses are expensive so she was not going to do anything wrong.

"Right, now tap the tube and make all the bubbles go up. Now squeeze the plunger at the bottom softly until some of the liquid shoots out of the tip of the needle. Good, now stick the needle into the soft fleshy piece that hangs round where the horse's penis comes out." Lorena hesitated. This would probably hurt the horse and that would be dangerous.

"Don't worry about the horse." The old lady said. Her voice, cracked with age, sounded as though she was happy to be inflicting pain on the beast. "He gets bitten there all the time and he will just think it is another fly. The most he will do is stamp his foot. Just hold it still once it is in." Lorena stabbed the needle into the required place and held the syringe still. The horse snorted and raised his hoof making his body shiver with the force of the stamp that followed. The old lady smiled down at Lorena.

"Humf. The old woman snorted. "Very good, I reckon that you are a natural." She said with a forced smile. "I shall look forward to the day when I see you ride. Now push the plunger all the way into the tube, and then pull the needle out of the horse's pouch." Lorena followed the instructions and then looked up at the old lady. "Now, you come to me in the house every day, and I will give you the syringe and you are to do this each time Neltitaca mounts up to ride like this." She snatched the syringe from Lorena and then turned and started out of the stables.

"But didn't that hurt the horse?" Lorena cried out. "Oh no dear, to the horse it is no worse than being bitten by one of those horse flies that are constantly bothering him." There was a horse cackle, then she was gone. Lorena looked back at the horse's penis. It was coming out of the pouch and growing stiff. She told Neltitaca of the development.

"Yes that is what is meant to happen, when it is long enough you must push the head into my vagina." Lorena reached down and took hold of the growing penis. It was firm and quite stiff but the surface felt spongy. It was hot and it throbbed in Lorena's hands, sending a pulse up her arm. It was like a machine that was just starting to work. The penis reached a length of about thirty five centimetres so Lorena pushed the thick head between Neltitaca's vagina lips.

At first it would not go in but Lorena held the lips apart with her free hand and slid the throbbing meat in with her other hand. It slipped in easily and as it did Lorena got a glimpse of the large hole in the older girl. She sat back on her heels amazed. How had that got so big? "Oh, that feels good, it has been so many months since I had him in there."

Neltitaca sounded as though she was in a dream, there was sweat all over her body. The penis continued to grow and it seemed to Lorena that Neltitaca would take it, no matter how big it got. As it penetrated the thick shaft pulled the lips of Neltitaca's pussy into her body a little and then they would slip out again only to be pulled in again by the expanding rod. After a few minutes the growth stopped and Lorena was able to breathe again. She had been holding her breath with anxiety at seeing the extent to which the shaft had penetrated the girl. She had known that horse's penises were large but had not realised just how much would fit into a woman.

Neltitaca gave a sigh. "All right, we can go now, I am sorry if it startled you the way it went in like that but once it started there was nothing I could do to tell you. It just takes over and it is so lovely." Lorena broke from her stunned amazement and went to work. She reached up and strapped one of Neltitaca's ankles to the harness. Then she walked round the back of the horse and strapped the other ankle. Both legs were held almost straight and well forward of the horse's hind legs.

This accomplished, Lorena moved forward to strap the wrists of the girl. Again they were strapped so that the limb was almost straight but this time the hands were allowed to hold on to handles that hung from the saddle of the harness. The horse stood still while all this was being done. The job finished Lorena stood back and checked her handy work. She could just slip a finger into the straps that bound hand and feet, so none of the straps were too tight. The girl was in the right position with her shoulders well back from the horse's front limb but her legs were out of the way of the hind legs. That was good.

It would be unlikely that the horse would be able to kick or otherwise injure her new friend. Satisfied with her handy work she walked round the horse to check it all again and took particular note of the state of the horse's penis as she did so. It was still thick and hard and seemed to be about half into Neltitaca's open vagina.

There was a thicker ring about half way along the penis. Lorena had seen it before. This ring was just at the opening to the juicy wet hole that engulfed the shaft. Not only was this a fascinating achievement but it was beautiful to look at as well. Lorena decided that she would have to learn to control the horse from the back where she could watch the penis at the same time. Niltitaca's voice stopped her reverence of the male phallus.

"Back the horse out and take us to the field by the river. We will be there for the rest of the morning. It should be warm and very pleasant." Lorena had no problem with this and as she encouraged the horse to reverse into the passage at the back of the stalls, she thought to pick up a riding crop from a rack on the wall. Once the horse was in the passage she led him on but while doing so she lengthened the leading rein to its full extent. This set the stage for the next step in her plan.

As the horse took its first step, Lorena heard the girl suspended under the horse give a deep gasp. She wondered what was happening to her that she had to utter such a sound. She looked back and could see the harness rocking forward and back. At the same time it swung sideways, to and fro.

Lorena wanted to watch but knew that she had to keep an eye on the direction of the horse and not let him go the wrong way or some thing dreadful like that. She pulled her eyes back to the front and concentrated on her new job. Leading the horse into the yard, she swung the horse round and headed for the gate to the path that led into the fields. On reaching the gate she opened it, walked the horse through, and then turned the horse round so she could close the gate. This done and the gate shut fast, she turned back to the horse, but instead of going back to the horse's head and leading on she swung part of the rein over the horse's head and across his back. This would enable her to stand well back from the horse's head butstill be able to control him.
