It isn’t often I come across something new, but that’s exactly what’s happened this year with my discovery of ovipositor dildos. Curious about ovipositors? You should be. These alien egg-laying fantasy toys are the pinnacle of perverse penetrative dildo design, showstopping spectacles of texture with xenomorph tentacles and otherworldly nodules to visually arouse and internally thrill. Read on for the sublimely slimy scoop on these sci-fi inspired sex toys that bring egg-laying kinks to life; what they are, why people are attracted to them and how to use them to broaden your sexual pleasure horizons.
What Are Ovipositor Dildos?
An ovipositor dildo is a fantasy sex toy designed to replicate the sci-fi alien or eldritch creature inspired act of laying eggs inside the body. Usually made from body-safe silicone, these sex toys have a hollow shaft which is loaded with eggs. During use, these eggs are pushed upwards through the dildo, with the help of some sex lube (aka slime, naturally), and deposited into the vagina or anus.
The design of these fantasy sex toys is usually otherworldly – think extra-terrestrial xenomorphic, Kraken-style beast from the dark abyss or the protrusion of a high fantasy being. Often, these toys feature pronounced tentacle textures, but some may be more abstract or playful in their designs.
Overall, the focus with ovipositors is turning a sci-fi fantasy into an intensely erotic, interactive reality.
Why Are People Attracted to Alien Egg-Laying Toys?
People find ovipositors exciting and alluring for a number of reasons, usually a combination of alienesque fantasies, submission to something non-human and various related kinks and fetishes. As with many things in this modern world, if you can imagine it, you can experience it – and we humans can have a very creative imagination indeed, especially when it comes to our sexual desires.
There are a few specific elements that play into the desire to use ovipositors, such as:
Alien sex fantasy: Some people have a fantasy of having sex with aliens or other non-human creatures, or exploring scenarios that go beyond human sex couplings.
Unfamiliar sensory thrill: The physical sensations of the eggs being deposited inside then glooping out of an orifice is strange and unusual.
Breeding kink: Having eggs deposited inside the body by an otherworldly being ties into fantasies of being bred by captors and related power play fantasies.
Taboo allure: It’s just so different, isn’t it? Wild, you could say. Doing something that feels so forbidden, weird, or ‘other’ can be a powerful turn-on.
It’s important to note that you don’t have to be into power play, alien sex fantasies or breeding kinks to enjoy ovipositor toys. For many, it’s simply about using penetrative toys that are different to the run-of-the-mill types, enjoying their bold designs and textures as well as the kinky sensations egg depositing and ‘laying’ produces.
How Do People Use Ovipositor Dildos?
Not gonna lie, I’ve found that using these alien sex toys requires a little more preparation than a standard penetrative toy. But oh my god, it’s so worth it.
Some ovipositor dildos come with eggs you can use, and I’d advise adding a big bottle of lube to your basket if you don’t already have some at home. Got any old towels? Set them down before you start. Make sure you’ve got plenty of time, so you’re not stressed or feeling rushed. Close the curtains and lock the door. Then, get ready to have your world rocked.
The ovipositor toys I’ve used so far have come with a set of matching silicone alien eggs. I’ve chosen to use the dildo and eggs vaginally, mainly as I couldn’t take the size of the dildos anally, but also because I don’t want to use silicone eggs anally as it isn’t safe. More on this in the next section!
If your toy doesn’t come with eggs – or even if it does – you can get creative and make your own DIY alien eggs at home. These could be made out of ice for thrilling vaginal chills (though not suitable for anal), or gelatin which is body safe and dissolves with the heat and moisture of the body. Vaginal suppositories are often made with a gelatin base.
Once you have your ovipositor dildo and eggs, it’s simply a case of using enough lube, knowing your limits when it comes to insertion into your chosen hole, loading up the eggs, getting comfortable and incredibly aroused, then enjoying the sensations and role play that follow.
There are no set rules for enjoying ovipositor dildos, just make sure you’re comfortable and that you keep play body-safe at all times. You might get off on full-on alien abduction and xenomorph breeding kink, or you might just absolutely love anything unusual, taboo or texture-laden during your erotic pleasure sessions.
Are Ovipositors Safe for Anal Play?
If you are a regular lover of sex toys and indulge in anal play, you probably already know that you should only use anal-safe products in that part of the body. Flared-base dildos or vibrators with an anchor outside of the body, for example. This is because the anal area, unlike the vagina, has no natural ‘end point’; anything pushed into the anus can travel up inside the body and become lodged at a point where it’s impossible to retrieve without an embarrassing and painful trip to hospital. I think we can all agree that’s something best avoided.
So, what about ovipositor dildos, where depositing loose, slimy eggs inside the body is part of play? Can you use these egg-laying sex toys anally?
Yes, you can. The biggest risk isn’t from the dildo, which should have a flared base at the bottom, but from the eggs. Solid silicone alien eggs should not be inserted anally, but you can buy or make anal-safe eggs from body-safe materials such as gelatin, agar-agar or medical or food-grade water-soluble capsules. These will break down naturally inside the body and are easily expelled, avoiding the usual risks attached to inserting loose objects anally.
One material type you might assume is safe when it comes to making alien eggs for anal play, but actually isn’t, is ice. Yes, it’s easy to make ice alien eggs at home, and yes, it melts quickly and easily. However, using ice in the delicate anal area where there are extremely sensitive and thin tissues can cause shock, physical damage, numbness and more.

Where Did Ovipositor Toys Come From?
As humans, we have long been fascinated with the unknown, the alien, the otherworldly and the horrific. Think back over TV series and films with cult followings, such as the Alien trilogy, the X-Files, Doctor Who, Stranger Things, and all those late-night Twilight Zone/Hammer Horror type programmes which spawned obsessions, kinks and fetishes. It’s unsurprising that sex toys to cater to these alien invasion fantasies would follow. Demand grew over the years, especially with the rise of online communities such as Reddit, where like-minded adults could discuss their shocking, strange or taboo sexual interests.
It was around the early 2010s when indie sex toy creators began experimenting with egg-laying dildos.
The fascination with ovipositors partly stems from sci-fi films, hentai, and monster erotica, where alien creatures often reproduce in unusual ways. These fantasies sparked curiosity in fetish communities online. The company Primal Hardwere are credited with making the first ovipositor dildo, named “Kraken”, and their popularity surged. These toys spread across kink communities, erotic fanfiction spaces and eventually, into mainstream sex toy shops such as SheVibe in the US and SexToysUK in the UK.
Ovipositor dildos exist in the same realm as tentacle dildos, dragon toys and other fantasy-inspired cocks. They may once have seemed a perverse oddity, but now they are part of a celebrated niche for those who want to explore role play and sensations different to the ordinary; the alien egg-laying fantasy being just one of many.
Are Ovipositors Still Popular Today?
Absolutely! There is still huge demand for ovipositor dildos, with more designs, sizes, colourways and additions coming along all the time. They remain popular because they’re an accessible, consensual and body-safe way to indulge in fantasies that could never become a true reality.
Ovipositors blend intense physical sensations with mild to extreme fantasies – and whatever that fantasy may be is entirely up to you. You might enjoy these egg-laying toys simply for the unusual sensations, or you might have a deep desire to be captured by an alien race who force you to submit and become their reproductive vessel, kept and bred for their ominous purposes.
Final Thoughts
Ovipositor dildos are not for everyone – but then, what is? Some people like nipple clamps, others would never. You might enjoy using a butt plug; for others, anal toys could be a turn off. Ovipositors are simply another style of sex toy which caters to specific sexual desires. They are the response to a huge global demand for a tangible product which fills the alien egg-laying kink niche.
Isn’t it incredible just how creative and varied human sexuality can be?
Perhaps you’re new to ovipositors, or they’ve been a fascination for you for some time. Either way, it’s easy to experience the kinky world of alien sex toys for yourself. Many online sex shops now provide a range of egg-laying fantasy toys at prices to suit all budgets. Dare to delve into this sensational world and you could unlock a whole new kink. I know I did.
