Christopher Booker once wrote that there are only seven stories in the world of movies and literature, and that those seven stories are: Overcoming the Monster, The Quest, Voyage and Return, Rags to Riches, Comedy, Tragedy, and Rebirth. I thought about this, and came to the conclusion that porno movies seem to follow a completely different formula from all other forms of writing, and wondered if I could find a similar formula to categorizing stories. After quite a bit of, ahem, "research," I managed to come up with my own list of the seven plots found in almost all porno movies and videos, as well as porn games and erotic stories. Naturally, one movie or story can include elements from multiple categories, but in each video or story, one category will tend to emerge as the dominant theme for each story. Obviously, this does not include pictures or short videos of people fucking without context, as such cases have no "story" to categorize. With that in mind, here is my list of the seven porno plots.
1. The "Dear Penthouse" Story - Named for the classic forum letters in Penthouse magazine, this plot features a protagonist, someone the viewer or reader is meant to identify with, and may even be a mostly or entirely POV shot, who finds him/herself in an unlikely sexual situation with zero effort. In this story, the protagonist is completely passive, and the other performers are acting upon the protagonist, apparently intuitively knowing exactly what he/she wants. A line commonly used in such stories is "I couldn't believe my good fortune," because all sexual acts are desired but unsought. Some examples include, a man delivering pizza only to discover a horny naked housewife, a boy masturbating in his bedroom being unexpectedly joined by his hot stepmother, a student being held after class by a hot teacher who couldn't help noticing his frequent erections, or a shy virgin suddenly being propositioned by his more-sexually-experienced best friend who he always had a secret crush on. In all cases, the protagonist takes no initial action, and the story ends with a gained experience and usually the promise of a continuing sexual relationship.
2. Boldness Pays Off - In many ways, this is the reverse of the "Dear Penthouse" story, being the same structure of events, but seen from the opposite character's perspective. In this story, the protagonist has zero reservations about initiating sexual acts, secure in the knowledge that the other person, although not having said so, is down for anything. In this story, the pizza guy does not stumble into the home of a horny naked housewife, but instead, he whips his dick out in front of the housewife, who is surprised but very grateful. Another key difference between this and the previous category is that if any third or additional players are present, in the Dear Penthouse story, they would more likely also be sexually assertive, while in the Boldness Pays Off story, they would more likely be additional passive players, although this does not need to be the case. The story ends with the supporting characters having enjoyed the experience. The protagonist, despite going completely against all societal norms and mores, does not face any consequences, such as prosecution, loss of job, loss of respect, or even the slightest feeling of embarrassment or awkwardness. When the sex act is over, the story is over, and the protagonist presumably moves on to his/her next encounter.
3. The Sexual Awakening - Unlike the previous two stories, which show only the protagonist's point of view, the Sexual Awakening story may include the thoughts and perspectives of multiple characters, though the main focus is typically on the "virgin" character. In this story, the main character is a shy or prudish and sexually inexperienced person. He/she may be a complete virgin, or may simply be a "virgin" to the specific act about to happen, such as having never before experienced anal sex, a one-night stand, a homosexual encounter, group sex, exhibitionism, bondage, etc. The "virgin" character finds him/herself coerced or even forced into a new sexual experience by an aggressor or aggressors. The virgin is reluctant or even resistant, but the aggressor intuits that the virgin will soon come around to enjoy the new experience. Sure enough, the virgin soon experiences a surge of sexual pleasure so intense as to completely change his/her character. Once the "pain has given way to pleasure," he/she finds him/herself involuntarily begging for more. The story ends with the former-virgin looking forward to a life of consensual sexual submission, and the aggressor having taken great pleasure in "corrupting" an innocent.
4. The Power Fantasy - In this story, the protagonist commits acts of sadism on an unwilling victim. Unlike the Sexual Awakening story, the victim does not come around, and the aggressor protagonist does not expect him/her to. The aggressor may use some form of financial coercion, blackmail, the facade of punishment for some invented misconduct, or simply kidnap and restrain the victim, and the act performed may be purely sexual, purely torture, or a combination of the two. Typically, the protagonist is out for his/her own amusement in the manner of a bully, not acting out of anger, but rather for the thrill of being in control of someone else. The story ends with the victim too physically and mentally exhausted to seek help, and the protagonist already planning his/her next assault. Obviously, stories like this are not for everyone.
5. Erotic Fun & Games - Unlike the previous stories, which almost entirely focus of some kind of first encounter, these stories revolve around friends and lovers whose sexual relationship has already been established, or at the very least, have a prior understanding of what is about to happen. In these types of stories, partners or groups may engage in uninhibited sexual acts with no one person being in a dominant position over any other person. Such egalitarian sexual adventures may include wife-swap parties, strip games, or full-blown pansexual orgies. Although the free-love environment lends itself to a lack of restraint, there are implied boundaries, as all the participants seem to already know each other's likes and dislikes. The story does not have an ending so much as the fun simply slows to a halt as the participants feel satisfied. Broadly speaking, this category also includes live-streaming webcam shows, as the viewers experience a parasocial relationship with the performers, and the social mores, although clearly defined, are far more sexually permissive than in a normal context.
6. Stealth Fantasy - This story may follow a similar setup to any of the previous five stories, but with the major difference being that the main focus is on the avoidance of being discovered by a third party, and the thrill of the risk involved. This may include a sex act in a public place, cheating on a partner, spying on someone, using a concealed sex toy, etc. Cartoon or prose fiction may also include major social taboos such as incest, pedophilia or bestiality, provided that the primary focus of the story is on maintaining secrecy. To a lesser degree, the Stealth Fantasy can also include solo pictures and videos in which the performer is trying to conceal his/her identity, thus creating a real-life scenario where the performer is engaging in a parasocial sexual interaction with online strangers, while maintaining secrecy from in-person acquaintances. A typical Stealth Fantasy story can end in a number of ways. The performer or performers may have successfully avoided being discovered, giving a figurative or literal wink to the camera. The performers may be discovered after the act is completed, giving a comical shrug, suggesting it was never that big of a risk to begin with. Or the performers may be discovered by a third party who, in an unsurprising plot twist, expresses an interest in joining them, or disappointment at having not been invited to join them. This is one type of story that lends itself well to comedy as a way of lampshading the absurdity of how oblivious the third party can be.
7. Meet and Fuck Games - Due to the necessary long-form of this type of story, it is found more often in erotic video games than in movies or stories. In this story, the protagonist encounters or is acquainted with a person, or more often, several different people, who finds the protagonist sexually attractive, but is unwilling to engage in any sexual acts with him/her until after they have gotten to know each other better, or until the protagonist has completed some sort of test. In many ways, this follows a similar structure to the Boldness Pays Off story, but with the difference being that the secondary characters do not immediately capitulate. Naturally, this lends itself well to the genre of video role-playing games. Assuming the protagonist is achieving sex with multiple separate partners throughout the in-game narrative, there are often also elements of the Stealth Fantasy. Such stories may also include complex nonsexual subplots, though they rarely impact the sexual elements, and could easily be done without.
