In High School Kent Phillips was a dipshit nerd - that's the only way to describe him. He had horn-rimmed glasses, a pot-belly, acne, hair that seemed impossible to control, and non-symmetrical facial features. His hygiene also left a lot to be desired. He was the perfect target for bullies, and there were no shortage of them in his school district.
A day did not go by in High School that Kent didn't get a wedgie. If that was all that happened to him it was a good day. More often than not, however, his books were knocked to the floor, his lunch money was "expropriated," glue was poured onto his hair, his head was shoved into a toilet, his glasses were broken, his shirt was ripped, and/or he was "pantsed" (his pants and underwear were pulled down to his ankles) and tossed into the hallway.
His parents were disconnected from him, had trouble making meeting ends meet, and their own sets of problems, so they weren't much help in stopping his bullying. The school that he went to ostensibly had an anti-bullying policy, but its enforcement was lackadaisical at best. The few times that Kent did complain it resulted in little punishment for the perpetrators, and more intense mistreatment of Kent in the future. By the time that he was eighteen, and a senior, he was resigned to his lot.
Even though he was resigned to his lot that did not mean that Kent accepted it. He harbored deep-seeded feelings of resentment and revenge, especially against his main tormentors. They were Bill Masters, Jack Jensen, Tom Pletcher, and Jeff Stevens. Two girls - Melanie Wilson and Kathy Korne - were almost as bad because their emotional abuse made the physical abuse he received even more unbearable.
Kent suffered his most humiliating and traumatic experience at the hands of Bill, Jack, Tom and Jeff, with Melanie and Kathy looking on, making nasty comments and laughing. The day after graduation from High School, while most students were picking up their yearbooks or socializing, the six of them cornered Kent behind the bleachers in the gym, gagged him, and while Bill, Jack and Tom held him down Jeff tattooed the word "LOSER" just above his buttocks. The letters were in different colors, and permanent. The pain was excruciating, and it required Kent to make a trip to the doctor to make sure it wouldn't get infected.
Kent kept a notebook with all the information that he could gather about his six protagonists, and his entry that day swore that there would come a day when they would get their comeuppance.
Despite his miserable reality, Kent had a rich fantasy life. The two subjects that he dreamt about most were sex and biomedical engineering - pretty distinct topics. Of course he had no chance to actually experience sex because no girl found him attractive, or even if a female was misguided enough to find him attractive she would never have the guts to even admit it given how Kent was scorned by everyone in his High School except for two almost equally nerdy friends.
Just because he had no chance with any female - in fact he was emotionally bullied by many of them, not just Kathy and Melanie - that didn't mean that he couldn't dream about porking them. From the time that he turned eighteen Kent imagined fucking every girl in his senior class, especially Melanie and Kathy.
Kent's visions about a future in biomedical engineering were far more pragmatic than his hallucinations of being a sex machine. While he was no genius, and had trouble with classes in the arts, literature, and language, he always did well in math and science. He also read everything that he could get his hands on relating to biomedical engineering even though he didn't have the scientific background to fully understand most of it at the time.
Not having good enough grades or board scores to get into, or enough money to afford, a university biomedical engineering program, when he graduated from High School Kent enrolled in Portland Community College. PCC was one of the few community colleges in the country that offered an associate's degree in biomedical engineering.
By working a part-time job, studying hard, and absorbing more and more during his voracious reading of anything biomedical, Kent got his associate's degree from PCC with honors. He did well enough that he got a scholarship to the University of Washington biomedical engineering program and got his Bachelor's Degree - also with honors - two years later.
Kent got a job in biomedical engineering in the Seattle area immediately after graduation. By then he was twenty two, his acne was gone, his glasses had been replaced by contact lenses, he had learned to practice good hygiene, he had gotten his unruly hair under control, and despite his distaste for physical activity had joined a gym and quickly lost twenty pounds. He was still no prize, but infinitely more presentable than he was in High School, and actually went out on some dates.
Kent also had a six figure income, and when he was twenty six invented a material that was eminently suited to provide successful 3D printing of various human body parts, including ears and toes. The company he worked for had a policy of providing a significant share of royalties to employees that came up with commercially successful products, and within a year Kent's already significant income had more than doubled.
On Kent's twenty eighth birthday he initiated three major changes in his life. The first was to make a deal with the company he worked for to work part time and that any inventions he came up with that related to non-traditional parts of the business would be his alone. The second thing that he did was to have his "Loser" tattoo successfully surgically removed, although he had excellent color photographs and transparencies made of it before removal. The third thing that he did was to have plastic surgery to make his face more attractive.
The three changes, collectively, which took place over the first month after he turned twenty eight, buoyed Kent's spirits so much that they started the creative juices flowing. They flowed so voluminously that he was able to master something that had been a dream in the back of his mind since the "tattooing incident," and that he now wanted to turn into reality. He came up with an initial version of his invention, improved upon it several times, and by the time that he turned twenty nine was ready for real world testing.
Kent called his invention "The Feedback Loop." It consisted of a number of electrodes wirelessly connected together so that they could in real time transmit the sexual pleasure that a female was receiving to her male sexual partner so that he could adjust his "activities" to enhance that pleasure. In addition to sensing the female's pleasure it also enhanced it by amplifying the electrical signals associated with that pleasure in the female's cerebral cortex and limbic system. Properly utilized it would allow a male to cause his female partner to experience the best orgasms of her life.
Kent began his real world testing on a prostitute - actually a call girl whose professional name was Ashley. Ashley was a reasonably attractive woman in her late thirties who worked about thirty hours a week as a nurse, masqueraded as a single soccer mom, and had her relatively lucrative call girl business as a sideline. Kent met her through a mutual friend and approached her on a "strictly business" basis. He required that the sex be without a condom, however, so both he and she were tested for STDs, and Kent hired her to work exclusively for him for one month, and made her promise to answer all of his inquires honestly since the testing of The Feedback Loop required it.
By that time, twenty nine year old Kent was actually a decent looking guy. While few, if any, women would call him "handsome," he no longer had any of the physical features that made him a target in High School, and actually had had a half dozen or so real sexual encounters with dates.
During Kent and Ashley's first three sexual encounters Kent did not use The Feedback Loop. He needed a baseline, and also, given his relative inexperience, needed to get comfortable with Ashley and her with him. Kent asked for, and got, her honest appraisal of his performance in those three encounters; decent, but below average, and no orgasm by Ashley (like many call girls she didn't actually orgasm often, although she was a master at faking them; at his insistence she did not fake an orgasm for Kent).
During the fourth sexual encounter with Ashley, Kent employed The Feedback Loop. He attached several electrodes to Ashley and two to himself. The receiver/transmitter that did the sensing and enhanced the pleasure signals to the brain was small enough to be hidden in Kent's pants pocket, which he put at the side of the bed.
Kent started out by fingering Ashley's pussy. She was much more responsive than she was during the three test sexual encounters. Next, he added oral stimulation to his finger play. He quickly learned what activities performed on her clitoris were especially pleasurable to her, and given the enhancement that The Feedback Loop provided to those feelings Ashley began significant squirming. When he located her G-spot and properly stimulated that at the same time that his tongue was exciting her clit, Ashley started moaning and flopping.
To his surprise not only was The Feedback Loop enhancing Ashley's pleasure, Kent himself was achieving a higher level of sexual excitement than he ever had before in his life.
