Chapter 1. Knowing Mariana Bujaidar
Mariana Bujaidar had just started her Senior Year at Miraflores Catholic Private High School run by nuns, the young light brunette with wavy hair below shoulder length and bright big honey-color eyes, enjoyed her status as one of the most popular girls at school, taking advantage of her 5´7 feet height and perfectly fit body that featured long-well-toned legs, flat belly, very firm 32 C cup bra breasts with perky pink nipples. The Caucasian skin tone young girl also had a big mouth with very kissable lips and a beautiful smile that made her bubbly personality evident.
At school, Mariana was between a B and an A student, captain of the varsity cheerleader team and president of the Senior Student Society. The young teens were constantly surrounded by friends, and other kids at school wishing they could all be a little more like her, even if she had developed a little bit of the mean popular girl personality, not that different from what you would see in movies like mean girls and such. Mariana often disregarded or looked down upon others that were not at her level and, at times, was even cruel to those less favored students or people in general.
At home, things were a mix of harsh relationships with her parents and luxury comfort. Mariana was the middle child of the three daughters formed by the marriage of Abraham and Carmen Bujaidar. The father, Abraham, fifty-four years-old and a rich businessman in the textile field and Carmen, the thirty-one-year-old stay-at-home mother with the occasional job helping her husband at the office were extremely strict and near religious fanatics, beyond casual conservative. Carolina, the older daughter, two years older than Mariana, already in college studying arts, at another town, and Kassandra, just a year younger than Mariana, attending Mariana´s same private catholic school. The family dynamic would often place Mariana in direct clash, especially with her mother, as the young girl wanted to live and experience the world, while Carmen would deny and hinder her daughters natural development, not out of malice, but out of ignorance, unlike her husband, Carmen had not attended college, and not even was able to finish High School, because of getting pregnant at a very young age with Carolina, her first daughter and the only one that was from another man.
Independently of how popular Mariana was at school, and the fact that she looked like a model, her upbringing made her extremely prudish, and conservative compared to most of her friends and classmates at school. Both her parents never allowed the young girl to take a Sex ED class at school, and talking about any sexual topic at home was simply not an option, at school, again, the nuns made sure to install a big fear of any sexual activity before marriage to their students. Something that most girls would simply brush off and ignore, but in Mariana´s case and considering her family, she took it seriously and considered most sexual actions as if a sin.
Financially speaking, Mariana had access to a lot of money, if her parents allowed and approved of whatever she wanted to buy, even a frappe coffee at the local Starbucks would have to be approved by her parents. Mariana´s debit and credit card statements would arrive directly to Abraham´s business office and even shopping a chocolate bar using any electronic payment method would be registered and monitored by the young teen´s parents.
Mariana´s love life was also strictly controlled, while she was used to having a lot of guys, younger, same age and even a couple of years older trying to get her attention, both her parents decided with whom Mariana could hangout and with who she could not. In many ways, Mariana lived inside a huge golden cage, full of luxuries, but with little to no real freedom to be all she wanted, still being there, just like that was a perfect comfort zone for her.
Unknown to Mariana, she was being observed and analyzed carefully at a distance, as plans were made for her, gathering as much information as possible before making the first move on the young brunette girl.
Developing a plan to lure and captivate Mariana was a man twice her age, making use of his assets and resources, slowly and deliberately the puzzle pieces he needed before the first move were falling into the right place, and the older man found a window of opportunity open one good Saturday, when he knew Mariana would be at the equestrian club taking riding lessons as she had just recently discovered her passion for horse riding and equestrian jump especially. Before starting his game with Mariana, the mystery man observed her at the equestrian club or a couple of weeks until he knew all would be ideal.
During the couple weeks before his first move, the older man had identified Mariana´s routine, and he had already began making rapport with the young girl, without yet even talking to her. The rapport began with extremely simple, yet vital things for all to run smoothly. The man was always dressed sharply and fashionable, always clean and with the same lotion scent, that way the smell will begin to trigger Mariana´s mind to think about him, a tall handsome man with a very strong body built and very fitness, always a gentleman with those around him, politely saluting Mariana with a simple “Good Afternoon” and a smile, but nothing else. At first, Mariana would simply respond, the same way, with a simple “Good afternoon.” But a week later the young girl was also smiling and being the one to begin contact, even if it was with a simple “Hi” slowly but surely getting used to the older man presence where she was and without rising any red flag in her mind.
Once Mariana was a little more used to the older man´s presence, it was time for the next step, still inside the equestrian club. The older man had identified how Mariana never checked if the English saddle was firmly strapped before placing a small step next to one of the equestrian club school horses, and then bluntly placing her whole weight on the stirrup as she finally mounted the horse. With that in mind, all the older man had to do was to pay the person that was supposed to check the saddle to simply not do it, and to not be there when Mariana was about to mount the horse, instead of the help, the only person around would be the older man, close enough to Mariana to save her from falling, which would provide the first touch and real ice breaker to further his plans with the young honey-color-eyed girl.
As expected, Mariana arrived at the equestrian club on Saturday and was not able to find anyone to help her mount, but because of her personality, the young girl didn´t think twice, grabbing the small step and placing it next to the horse she was supposed to mount. While Mariana was getting ready, the man twice her age was also getting his horse ready to be mounted. Mariana, as she always did, lifted her leg and placed it on the stirrup with a small jump, letting all her weight in it before moving her other leg to finish the mounting movement, and just then, the saddle turned, now resting on the horse belly instead of the horse back, the young teen had one hand still firmly holding the bridles as she began to fall down on her back for a moment, before the older strong man caught her, preventing her from falling as he kept hugging the young girl, carefully making sure that the hug both prevented the fall, but also kept Mariana very close to him in a somehow romantic move. At the same time, the older man scared the horse a little, in a way Mariana would not notice, but that would make the horse accidentally hit Mariana slightly, not to cause pain, but to make the young girl extremely nervous about mounting the same scared horse right away.
“Careful there… are you ok?” The older man said as he kept Mariana hugged, but easing the hug a little to allow the young girl to turn as he looked at her deeply in the eye, before he slowly began to let Mariana touch the floor with her feet as tried to stand up properly.
“Uh, yeah, thanks, Mr. Heart, you saved me from that fall… I… I am ok now.” Mariana responded, already using the name she had heard when others talked with the man now standing in front of her.
“Nothing to thank about, I am just happy I was able to catch you, the thought of such a pretty girl getting hurt would be a hard one, so, what you said your name was?”
“Oh, right… I am Mariana Bujaidar, I am still a little bit new riding horse.”
“I have seen you around, and you don´t seem to be that new, you are good at it, anyhow, you know what they say, not only to build character but to recover from a horse fall, well near one, you need to mount again, right away, come let me help you.” The older man said as he began to rearrange the saddle, but once again, carefully and without Mariana noticing, scaring the horse a little.
“No way I am mounting that thing again, at least not now,” Mariana responded as she saw the horse ready to have her butt hit the ground as soon as she mounted it.
“I see, come, this one is my horse, as you can see is a black Andalucian stallion, his name is Bucéfalo, it means Bucephalus in English, like Alexander the Great's horse, because not only he is black but also has that cute white star on his forehead,” Mr. Heart said as he mounted the horse in one swift move and approached Mariana, extending his hand, motioning her to grab it so he could help her mount. “Come, mount with me a few steps, then practice your riding with him, while I go get something to drink.”
Mariana extended her hand and with the right motion was now sitting in front of Mr. Heart in the same English style saddle, but not being handed yet the horse reins, which had Mariana pressing her back against the older man´s chest as Mr. Heart´s arms were at each of her side, not hugging her, but controlling the horse, the scent was now familiar to Mariana, same as the feeling of the strong arms at each side.
After about a minute of dual riding, Mr. Heart whispered in Mariana´s left ear as his left hand was now taking the young girl’s front shoulder and pulling her even closer to him. “Ok, I will go get my drink now, be ready to take control of Bucephalus.”
Just then, Mr. Heart´s hand, the one holding the reins was innocently pressed nearly directly on Mariana´s virgin pussy, not cupping it, but a faint brushing as Mariana took the rains with both her hands and Mr. Heart´s hand was instantly removed, and with one move he was off the horse.
“Take care of your new friend, see you in a bit, Mariana,” the man said before parting and letting Mariana ride for a while on a real horse that was not usually handled by all the equestrian club students.
Before Mariana ended her practice, Mr. Heart was already waiting for her as the young girl approached, still mounted on the horse. “Wow, Bucephalus is so nice and gentle, thanks for letting me practice with him,” Mariana said as she prepared to dismount.
“Wait, come, let me help you,” Mr. Heart said as Mariana allowed the older man to help her dismount, and expertly, Mr. Heart made sure to give Mariana an extra special hug and firm handling while helping her.

“There you go, and really, he was so nice. He really is… like a little devil, not easy for him to take a liking to someone, guess you must be special… tell you what… you come here often?”
“Uh, really, he was very nice with me and… yeah, I come every Saturday, you surely have seen me around, don’t you?”
“Uh, not really, but I will be more attentive next time, anyhow, I ask because its rare for Bucephalus to be so nice, he must really like you and riding school horses is not really good, those horses are handled by so many people that they never get a proper style, especially if your intention is to enter competitions and such, here is the deal though… I can´t be here every Saturday, but I would love you to be Bucephalus rider, keeping him happy and well trained, on Saturdays when you are around here.”
“Really? That would be awesome, thanks.”
“It’s a deal then, well, in payment, next time I am distracted and don’t notice you around, you are to approach me and say hello, deal?”
“Uh, sure, I can do that. is a deal,” Mariana said as she smiled, not knowing that Mr. Heart was already starting to create the synapses and mental connections that would help him move forward with his plan at a slightly accelerated pace. Now, he could play the little game of pretending to be hard to get, while the young teen would chase after him and make sure the older man noticed her and not only that, but being the one to approach at least to say hello.
Mr. Heart then extended his hand. “Ok, let´s shake on that.”
“Sure!” Mariana said as she giggled and extended her hand to shake the older man´s hand and feeling the firm, confident hand shake he was giving to her.
“Ok, now let me take care of Bucephalus and get him to his stable, we don´t want your boyfriend getting jealous, do we?”
“Naw, I still have a bit of time before I have to head back home, least I can do is help you get this beautiful stallion to his stable.”
“Ok, help me out then.” Mr. Heart said as he made sure that Mariana felt like she was helping a lot while taking off the saddle from the horse and placing Bucephalus in its stable and the whole process.
“Oof, Ok, now I really need to get back home, or my mom will get bonkers,” Mariana said.
“Ok, drive safe and hope to see you soon,” Mr. Heart said, but without letting Mariana react, the man stepped forward and took Mariana with confidence by the back of her neck.
Still standing in front of her, four fingers behind the neck, keeping Mariana in place, as his thumb lifted the young girl´s chin slightly while the palm gently moved to take the girl´s face, he then gently and very softly kissed Mariana´s cheek. Mr. Hert´s free arm hugged the young girl for a second longer than needed and then let go.
“See you around.”
“Uh… yeah, we will…” Mariana said as the man had completely let go of her, and she somehow felt like she wanted to feel his hand on her face, the warm touch.
With the simple goodbye soft kiss on Mariana´s cheek and seemingly innocent way to grab her neck and face to pull her closer for a friendly hug, Mr. Heart was also ensuring that the young girl was getting used to his touch and crave for a bit more intimacy, same as for the fact that the next time Mariana approached to salute him, she would do so with a kiss and a hug, which was barely the first step to start getting the young girl used not only to his presence but to the touch too.
The following two weeks, Mr. Heart made sure to bump into Mariana not only at the equestrian club, but near her school, at the grocery store and a couple other places the man had already studied very well and knew the young teen loved being around or had to be around. As expected, Mariana was now approaching the man with more confidence and actively evading her parents' gaze at times to stay a little longer talking with Mr. Heart.
During those two weeks, aside from the small chat, Mr. Heart and Mariana had already exchanged phone numbers and were texting each other with more frequency, at first, talking about horses, and Bucephalus, same as for Mr. Heart giving Mariana some tips, but slowly Mr. Heart began to change the talking topics, from horses, to more personal and adult material issues, the transition between superficial and none-relevant topics to the ones Mr. Heart was interested to start discussing with Mariana so he could begin to mold her mind, came softly, in a way Mariana never saw it coming, transforming a simple question at a very specific time of the day, into something more.
The day Mr. Heart and Mariana´s texting began getting more serious began with a simple text from Mr. Heart, at the right time, just a couple of minutes before lunchtime at school. “Hey, Mariana, question… Pizza… pineapple or not?”
“Miguel… omg, really? I am starving right now, and you talk about food? And yes, true pizza has pineapple,” Mariana texted back, already using Mr. Heart´s name.
“Come here and have some then, you would also pair nicely with today´s model.” Mr. Heart replied and attached two pics. The first photo of a Hawaiian style pizza from Mariana´s favorite pizza parlor and perfectly knowing that it was also Mariana´s favorite. The second photo of the female model he was working with that morning, the model photo included her with Mr. Heart and a slice of pizza.
Since Mr. Heart started texting and chatting with Mariana, the older man had been carefully guiding the conversations and fishing for answers, gathering as much innocent personal information about the young teen, knowing that every piece of information, no matter how superficial or mundane it seemed to be, would be of great help.
“Omg, is that… it can´t be… she is super famous, like… she has thousands of followers on Instagram and TikTok, I actually follow her too.”
“Yeah, she is one of my girls, been working with her and helping her out to become the best version of herself. I see an even greater potential in you, if you simply gave a leap of faith and came here, grabbed some pizza and started gathering thousands of followers on your social media, uhm, do you even have social media?” Mr. Heart replied, already knowing about Mariana´s social media accounts and how little followers and boring reels or photos she uploaded. Mr. Heart knew how she wished she could be like a model, and have thousands of followers, not only from school, but all over the world, but her own upbringing and her parents were hindering that part of her.
“Oof, wish I could be there, I would not mind doing a bit of modeling, even if I don´t know how… Still, my parents would never allow it, and they do have access to all my social media… but you should save a piece of pizza for me.”
Mariana´s response was gold, an opportunity for Mr. Heart to start drawing a line and distance between her and what her parents represented, pushing her softly to be a little more rebellious, and to crave living her own life, under her own rules.
“I know what you mean, Mariana, when parents are too strict and hinder your growth, look at my model today, she should be at school right now. Instead, she is here, taking some glamour photos with me. Don’t think you could do the same, even if you were here right now to earn that piece of pizza”
“Of course, I could do the same, but I want two pieces.”
“Oh, really, let us imagine then, you are here, wearing your cute school uniform, standing in front of me while I set all the cameras ready and the green screen is behind you…” Mr. Heart began to describe the background for a small roleplay game, where Mariana would be the model and he would be the photographer taking very suggestive glamour photos. A small role play session with the young High School girl that included several sexual hints, even if they were still covert, and made in a funny tone, more than a serious one, having Mariane feel relaxed and soon getting into a far flirtier mood. The way older man perfectly knew by then that Mariana was already during lunch period at school, and he had the young teen engaged in a flirty roleplay game with small sexual hints, texting back and forward, which meant that instead of heading to the cafeteria to gossip with her friends, Mariana was focused on him.
Independently, if Mr. Heart would have loved to keep talking with Mariana for hours, he knew he had limited time, since as soon as lunch period time at school ended, she would have to head back to classes. The man had to be smart, not to press too much at first, so he kept in mind to start the small roleplay game, just a couple minutes before lunch time and ended five to ten minutes before lunch period ended, allowing Mariana not to feel pressured and usually having the girl reply with a photo of what she had for lunch that day or a selfie.
For the next few days, Mr. Heart was the one who started the texting a couple minutes before lunch, sometimes simply teasing Mariana, others talking about food or topics they have discussed the previous day, while giving a couple nudges on the chat to take the innocent chatter into a mode adult sexy one. Texting Mariana around the same time was not only to talk with the young girl for a bit and then continue with his day, for Mr. Heart it meant a life structure, planning and creating connections on Mariana´s mind.
Soon, once Mr. Heart had Mariana hooked with the regular texts, the man stopped texting first, Mariana was now already texting first, a few minutes before lunch when the older man didn´t texted first. Same way, in the middle of her lunch period, Mariana would text Mr. Heart, sending a selfie or a pic of what she was about to eat. The young teen had already started to make it a tradition and part of her daily routine to send Mr. Heart a text at specific moments throughout the day, and when she felt bored and that the conversation with her friends or parents was not good enough, Mariana found herself texting the older man constantly, craving for his more mature and worldly talk and the fact that she could be herself and milk the man for knowledge and information the nuns at school or her parents would never share - especially the sexy information that the daily small hints on Mr. Heart´s mini roleplay games had kept nurturing and keeping the girl´s curiosity high.
After about another month of constantly bumping into Mariana and daily small texts or calls, Mr. Heart had the young girl where he wanted, he had been carefully preparing the emotional rollercoaster, he has taken Mariana to a big emotional height and now he had to bring her down, up and down, breaking the young girl´s mind and then her body. The way older man knew that in order to mold Mariana into all he wanted her to be and become, he would have to break her first, make her become a white canvas where he could create a Masterpiece that would later on be the inspiration for many other girls like Mariana to join. Mr. Heart though, knew that the work on Mariana would be slow and harsh, but totally worth it.
For the next step, Mr. Heart waited until it Saturday, at the usual time Mariana went to the equestrian club to ride, now Bucephalus being the only horse Mariana used. That day, things were normal at first, Mariana searched for Mr. Heart to say hello before heading to the stables, the practice was fairly normal, but when Mariana as about to finish her practice she noticed the older man there, looking at her, but there was a different look on his face, not as if he was angry, but as if he was disappointed and worried about something, constantly looking at his phone and then at Mariana.
At first, Mariana brushed off that sensation that something wasn´t right, she dismounted and walked the horse towards where Mr. Heart was, a spot where there was no one around, close enough to hear what he would say or show Mariana.
The young brunette teen approached the older man, her right-hand holding Bucephalus reins, her ridding helmet still on her head as she tried to take it off as soon as she arrived with Mr. Heart with her free hand, her eyes first looking at Mr. Heart´s colder expression and a cute gift box he was holding with his left hand, while looking at his phone with the right hand, clearly preventing Mariana to see what he was reading or looking at in the phone.
