Object insertion Stories
Object insertion is the tag for everything that goes inside a body and wasn't part of another body: the speculum and the dilator, the bottle neck, the hairbrush handle, the candle, the gear shift, the glowing probe of something that isn't human. Dildos and plugs count, but the stories readers come here for usually reach further than a drawer of toys. The pull is simple. An object is cold where skin is warm, hard where flesh gives, and it never tires or hesitates. It doesn't care how you react, and the person wielding it gets to watch you take it with total attention. That combination of exposure, stretch, and clinical control is what makes an insertion scene land harder than a plain fuck for a lot of people.
Within the kink there are a few dynamics that come up again and again. Medical play is the biggest: exams that go on too long, instruments swapped for larger ones, a doctor narrating exactly what your cunt or ass is doing around the tool. Improvised household insertion is the second, where a lover, a captor, or a bored roommate grabs whatever's within reach and the humiliation is that it worked. Solo scenes lean on the same shame in private. Sci-fi and horror give you tentacles, ovipositors, machines, and alien tech that don't have to obey anatomy. Size and stretch training, temperature play with ice or warmed glass, sounding, double penetration with a toy alongside a cock, and public degradation where objects are used as party tricks all live under this tag too.
The stories currently on this page cover most of that ground. There's a cybernetics clinic where a specialist tests a rebuilt vagina and uterus instrument by instrument, checking sensitivity with the detachment of someone calibrating a machine. There's a game-day party where the only woman present is the prize, and the winners of each quarter use their bodies and whatever's on the table to collect. Two cartoon sleuths get strapped down on an alien ship and explored by glowing appendages that push past comfort into something else. A broke engineering student answers a camera club ad for an inexperienced model and finds out what the members actually photograph. And a captured agent ends up on a mad scientist's table, her body the subject of his experiments. Bondage, exhibitionism, and dubcon show up as frequent companions.
If none of these hit the exact object, hole, or power dynamic you had in mind, RedQuill lets you generate your own object insertion story from a prompt, so the speculum, the bottle, or the tentacle can be exactly the one you were picturing.

object insertion FAQ
What are object insertion sex stories?
Object insertion sex stories are erotica where something other than a body part is pushed into a vagina, ass, or urethra: medical instruments, bottles, vegetables, brush handles, candles, machines, or alien appendages, as well as conventional toys. The genre focuses on stretch, sensation, and the vulnerability of being filled with an unfeeling thing. Common setups include prolonged medical exams, improvised household insertion, captivity scenes, solo experimentation, and sci-fi probing. On RedQuill these stories are tagged under the Fetish parent category.
Is object insertion smut the same as sex toy stories?
Not quite. Sex toy stories cover dildos, vibrators, and plugs used more or less as intended, and the toy is usually a supporting detail. Object insertion smut treats the thing going in as the point, and it's often something that was never meant for sex: a speculum, a bottle neck, a gear shift, a tentacle. The appeal leans on improvisation, humiliation, size and stretch, and clinical or forced dynamics rather than mutual pleasure with a vibrator.
Where can I read object insertion fanfic?
This page collects object insertion fanfiction and original stories in one place. Fanfic under the tag often uses cartoon, anime, game, and sci-fi characters, since those settings make alien probes, machines, and captivity scenes easy to justify; one story here has two well-known mystery-solving sleuths abducted and examined. You can also generate your own object insertion fanfic on RedQuill by naming the characters, the setting, and what gets used on whom.
What is the difference between RedQuill and Literotica for object insertion stories?
Literotica has a large archive of user-submitted insertion stories, but it isn't organized around this kink and finding them means digging through Fetish or Toys categories. RedQuill gives object insertion its own hub with community stories sorted by tag, and it also lets you generate a new story to your exact specifications instead of hoping someone already wrote the bottle, speculum, or tentacle scenario you want. Both are free to read.
Why do people like object insertion stories?
Readers like object insertion for the contrast between an unyielding object and a yielding body, and for the exposure that comes with it. An instrument or bottle has no feelings, so the scene becomes about being watched, measured, and stretched rather than about mutual affection. That suits medical play, captivity, degradation, and solo shame fantasies. The Japanese search 挿入シーン, literally insertion scene, and old Tumblr tags point to the same appeal: the moment of penetration described in slow, physical detail.
