Smut 101: The Verbiage of Filth.
Hello, my fellow fanfic writers. Todayâs article is going to be about filth and smut. Yes, folks, this post is going to be full of graphic, graphic language, and so I suspect that you may not want to look at this while youâre at work or in class or on the train. Or you might want to live dangerously and do so anyway! It takes all kinds of folks to write fanfic.Â
Since sex is a huge topic, Iâm going to break this article into installments. Today Iâm going to work on a general topic, which is, how to actually describe smutty things. This will be pairing-agnostic, so be prepared to see graphic descriptions of all kinds of sex. I will follow up later with specific guidelines for writing sex between gay people, lesbian people, het people, and transgender people.Â
But first: the verbiage.
One of the things I run into from time to time is someone commenting half-jokingly that theyâve run out of synonyms for âtongueâ or âcockâ or whatever body part involved. Heh. I donât usually have that problem. I canât say Iâm like, the porniest of fanwriters, but I seem to manage pretty well.Â
My approach to idealized porn (the kind one finds in fanfic) is generally covered in these points, which I will elaborate on further down.
Euphemisms are suboptimal
Specificity is good
Sensations and feelings are good
Purely mechanical descriptions not so good
1: Euphemisms are Suboptimal
Some writers, especially those in the well-worn Mills and Boon or Harlequin romance genre, like to be flowery about their smut. The penis is a âfirm stalkâ, the vulva a âdewy blossomâ, the mons veneris a âdowny moundâ. This is what I call âgardening manual sexâ, where the body parts are so veiled in euphemisms that someone might take it as a gardening manual.Â
Donât do that.Â
Why, you may ask. Well, hereâs the reasons why I donât generally employ such terms. Firstly: If youâre writing smut graphic enough to require the naming of genitals, itâs definitely NSFW. And if itâs definitely NSFW, then there are perfectly cromulent terms for genitals that arenât as clinical as âpenisâ or âanusâ.Â
âCockâ and âcuntâ, âassholeâ, those are perfectly good terms, and if youâre writing graphic sex there really isnât a point in pulling a veil of euphemism all over whatâs going on. Doing so can lead to obscuring of whatâs actually going on, and if the writer handling the scene isnât good with euphemisms youâre going to wind up with horrors like âyoghurt-shooting purple-headed warrior of loveâ.Â
No. There is a point where euphemism crosses from obfuscatory to ridiculous. Best to just avoid the obfuscation and be honest about what your characters are doing: mashing erogenous zones together and having fun.Â
2: Specificity is good
When writing about sex, you may feel tempted to just gloss it over. If so, thereâs always the handy fade-to-black, which can salvage a ficâs rating from NC-17 to PG-13, depending on how soon you fade.Â
But if youâre writing serious smutty filth, then that approach is going to be a bit unsatisfying to readers. At the point where folks are looking for smut fics, they generally have various kinks they want to read about. Those kinks can range from âa little leatherâ to âbeing painted with polka dots and spanked with a tasselâ. (Iâm being purposefully ridiculous here as actual kinks can be triggers for some folks and I want this to be accessible.)
A vague sex scene can leave readers unsatisfied. âBut I came here to read about Kylo Renâs enormous penis!â etc. This is where being verbose and chatty will help. Talk about what theyâre doing to each other. How, and when. Talk about the physical end of the acts. How are they positioned? Make sure you keep track of hands and other body parts, lest you have something that doesnât make entire anatomical sense for the individuals you are writing.Â
This is where a very good imagination, or a pair of artistâs dummies or a modest porn habit can come in handy. From there you can figure out position and plausibility for various kinks. Donât forget foreplay, either! Foreplay is fun, and it helps whet the readerâs appetite for the main course. Besides, sex isnât always just genital focused. Mouths and hands can do very naughty things even if the loins are otherwise occupied.Â
Do they talk to each other? In which case you can turn up the heat with some filthy talk! Maybe they talk to each other about how good it feels. How perfect it is. Maybe they discuss filthy fantasies with each other. All this can add an emotional and psychological aspect to the physical acts, which is an added bonus!
3: Sensations and feelings are good
Sex is supposed to feel good, else your characters wouldnât be having so much of it, no? This point is very closely related to #2: Specificity is good. When trying to write an act, donât just describe it as feeling good. Thereâs a whole list of other things you can describe along with the mind-blowing pleasure of it.Â
The texture of their skin (smooth, callused, stubbly, soft)
How their body feels (sleekly muscled, firm, bony, yielding, cuddly)
How a specific act can feel on a sensory level (slick, tight, velvety)
Donât forget temperature (rapidly cooling breath, shocking blood heat, molten
What kinds of lubricants are they using (oil, water-based, slippery, thick or thin)
Body-feelings (their heartbeat against their loverâs back, pulse ringing in ears, the rising tension of impending climax)
Scent (are they wearing scent? what scent? smells from work or shower? shampoo, soap, musky sweat, spent gunpowder?)
Tastes (salty, sharp, sweetish, oceanic)
Being specific with sensations and feeling helps ground the smut in a characterâs mental and emotional world. Itâs not just an act, itâs not just something that is happening, but rather, something a character is a participant in. It ups the emotional power of the scene, and it makes it easier for a reader to identify with whatâs going on.
Also, in a more writerly sense, descriptions of sensations help pad out a scene so youâre not constantly figuring out euphemisms for âtongueâ or âpenisâ.Â
4: Purely mechanical descriptions are not so good
This is related to #1: Euphemisms are suboptimal. In shying away from euphemisms, authors can go too far the other way and wind up writing what I think is âfurniture assembly pornâ.Â
This is where the smut is purely action. Something goes in something else, and it moves in and out and in and out and feels good, but the sensation is not elaborated, not until one of the characters (or both) bust a nut.Â
If the sex act is the only thing thatâs going on, then one might as well watch a pornographic video or whatnot. The ability of text and prose is its ability to also convey things other than the physicality of the act: how it feels as in #3: Sensations and feelings are good. How it also feels emotionally, which has a great impact to a reader.Â
I may be biased against purely mechanistic descriptions of smut because most, if not all of my shagging in fic happens to have emotional reasons to happen. Theyâre afraid of talking about their emotions, so they try to express it with sex instead. They mistake eroticism for intimacy. They love each other, but canât admit it so they wind up having sex with proxies instead. They love each other, and enjoy sex with each other, and trust enough to discuss fantasies frankly. Things like that.
It is this added dimension where I like a lot of my fanfic to hang out - smutty but also emotionally authentic, and thatâs why I follow the various guidelines I state above.Â
How does this come together? Well, hereâs a bit from a WIP Kylux fic that might establish how I use sensation and emotion, specificity and just a bit of mechanical description to make a whole smut scene. (Itâs from chapter 2 of Attack of the B-Team, if youâre wondering.)
âSo tell me,â Hux panted softly as he got up to kneel between Renâs legs, âtell me how youâd like to see me fucking someone else. Tell me, and Iâll give you what you want.â He grasped at Renâs hips and crouched low, his plush lips brushing gently over the head of Renâs cock, and Ren shivered, thrust reflexively upwards against the warm tease of his breath.
âI want -â Ren managed, trying to order his thoughts. âI want to see him undressing you like a present,â he said, gasped and groaned as Hux wrapped that wet willing mouth around the head of his cock, âAll those layers you wear.â
âI want him to seize you gently by the necktie to start, almost like a strangle. All those god-damned buttons on your waistcoat,â Ren continued, his stream of consciousness starting to overflow its figurative banks as Hux continued his ministrations. His tongue was like velvet, his teeth sharp and very careful as Ren bucked up against him. âGod, to see you choking on someoneâs cock. Maybe even someone bigger than me.â
Ren felt Hux pause and shudder before those fingers tightened on his hips, but the bruising pain grounded him against the slick glide of Huxâs mouth, of that perfect wet heat. âWouldnât you like to show me how much you can take? Maybe youâd ride him into the mattress like you do me?â Ren was babbling now, trying to stay coherent as his world began to fall to pieces.
âWould you bareback and let him come in you?â Ren gasped, his eyes shut to his room, the walls and ceiling so familiar after these months, and the shelving he had put up to hold his books and comics. It was all too easy to picture, with his rich visual memory, what Hux would look like riding someone elseâs cock, the flush of his face and chest, his head thrown back to expose that sweet neck, beads of sweat running down his chest and back and shoulders. A galaxy of freckles traced by someone elseâs hands. âIf you did - oh, oh - if you did,â Renâs voice had gone husky with sheer need, âyou could let me lick you clean.â
Ren was thrusting helplessly up, fucking Huxâs perfect mouth, and he felt those fingers squeeze hard on his hips again. Continue, they said, or Iâm going to stop and leave you here like this. âYou wonât even have to untie me,â Ren managed, his teeth chattering as he started to shudder uncontrollably, âyouâd just have to back into me until I didnât have the room, until I had to, until I -â Ren felt Huxâs tonsils click against the head of his cock then, whimpered through his teeth as the fantasy started to tip him over the edge, those lurid thoughts and Huxâs clever mouth. He pulled hard against the cord binding his wrists as he climaxed, felt Hux swallowing around him. It was as though his skull had exploded in a burst of white and silver, his thoughts scattering like shrapnel to bounce lightly and ring against the very boundaries of his self.
Hux kissed him lightly, gently, all the way up his belly and chest, against the dip between his clavicles, let him come back to himself. Ren opened his eyes to find that Hux had loosed the knot and let his hands slip free, and he flexed them a little against the slight numbness that had accumulated.
Note the above:Â
Iâm very specific about what is going on. Ren is lying on his back. Hux is crouched between his knees, and he holds Renâs hips and gives him a blowjob. Ren talks frankly about his fantasies during the act. The bit where Hux ties him down is in a paragraph before this excerpt, but I come back to it and describe Ren pulling against the cord, and the numbness in his hands. We know where the hands, mouths and genitals are, to establish a good, solid mental image for the reader.
There are no euphemisms, but it is not purely physical either. I donât use euphemisms at all. Instead I use adjectives and descriptions. Plush lips. A tongue like velvet. A slick, wet mouth doing clever things. Leavening the descriptive bits with detail and sensation also helps prevent it from being purely mechanical. The reader is quite clearly informed how Ren is feeling, from the light scratch of Huxâs teeth to the numbness in his hands.Â
Thereâs an emotional aspect to this. This is mostly my specialty - smut with feels - but I balance off the kink (light bondage, dirty talk) with trust. Ren isnât afraid of being tied up by Hux. Heâs comfortable enough to talk about filthy threesome fantasies, too - ones that might endanger a relationship if tried. He trusts Hux not to be jealous. And Hux wants to listen to Renâs fantasies, encourages him with his actions to keep going.Â
This establishes that it isnât just sex for them, thereâs a strong bond of trust and affection and love, and that helps set the scene within the emotional reality of the fic itâs in.Â
Aaaaand: thatâs a breakdown of how I write smut, on a surface and deeper level, and why I use the verbiage I do. My next installments will cover different configurations of sex for different configurations of partners along the gender spectrum, realism or lack thereof, and the realities of lube, so sit tight and keep writing, yâall.Â
