After loving my first ovipositor recently, I was delighted to receive this max texture, tentacle spectacular from the ever-arousing Nothosaur Toys range. In today’s Nothosaur Kohana Ovipositor review, I’ll be going deliciously deep with this gorgeous, twisted tentacle dildo which came with a storage pouch, push rod, alien egg making trays in small, medium and large sizes as well as a ready-made set of silicone KoXeno eggs.

Preparation
I knew I’d need lashings of lube to successfully conquer the Nothosaur Kohana. Luckily, I recently invested in a jumbo bottle of water-based lube – perfect. Even with loads of lube, I knew there was no point trying to insert this large Kohana dildo anally; this is definitely a vagina-only toy for me. The squishy tentacles at the top of this dildo, around the opening which leads to the hollow centre, mean that attempting to insert it into the extra-tight anal entrance would be… challenging. Plus, I have the large size Kohana dildo, which isn’t as massive as some of my other large tentacle dildos, but it’s still far too big for me to take anally. It was enough of a challenge vaginally!
There’s also the factor of safe anal play to consider. If I could take the dildo anally then I’d enjoy doing so, but I wouldn’t use the alien eggs inside, as they could get lodged deep inside or even sucked up completely into my body, and this isn’t a worry during vaginal play. And in that event, why would I use a hollow-centre dildo for anal stim? I have plenty of other fantastic, solid, anal-safe dildos from Nothosaur Toys to enjoy!
When it came to using the Nothosaur Kohana Ovipositor Dildo, I found it best to give myself plenty of room and throw down a few towels as well. Not just due to the results of gushing arousal and orgasm, but also the amount of lube required and the high chance of lube-slicked silicone KoXeno eggs pinging from various places. Plus, it’s great to be able to put the large lubed up dildo down whenever I like, mid-session, without worrying about it picking up dust or fluff.
Taken by Tentacle Texture Overlord: Kohana
I found it easiest to use my Kohana Ovipositor when I was either kneeling or squatting over the toy, whilst on a steady, comfortable surface with furniture nearby in case I needed something to hold on to, to steady myself. It’s a very intense ride. As usual when preparing to take an enormous dildo, especially one with such magnificent, twisted tentacle texture, I made sure I was extremely turned on before putting the dildo anywhere near my puffed-up, lube-slicked labia. I find my favourite bullet vibe and reliable pair of nipple clamps help with this every time.
Once ready to be taken by the great tentacled beast Kohana, I made sure there was plenty of lube around those tendrils at the top – enough that it was oozing down the sensually textured sides. Holding it in one hand, I parted my vulva area with the other and gasped in erotic pleasure as those flexible fronds around the tip made gentle sweeping contact with my hot and aroused intimate area. Each tentacle tip felt wonderfully alien as they roamed over my aching with need labia and flicked across my throbbing clit, teasing me as they swept across my dripping vaginal entrance which hungered to envelop the entirety of this kinky, complex xenomorph protrusion.
Using it on myself firstly without any eggs inside, it was tricky to gather up the tentacle-tips at the top of Kohana to penetrate myself with the thing. Nevertheless, she persisted – and with the help of the lube and my natural arousal, finally succeeded. It’s impossible to accurately describe the sensation as one of the most sensitive regions of my body slid down over what could be the most textured dildo I’ve sat on to date, as all coherent thought left my mind as I gave myself over entirely to the primal sensations.
Filthily Filled with Kohana’s KoXeno Eggs
I thought it would be easier to stuff this beast inside when it was full of alien eggs, but without a stopper at the base I had to cover the bottom with one hand to stop the slippery eggs pinging out of the bottom of the just-as-slippery dildo. Everything was coated in supremely slippery water-based lube, which was spectacular for heightened sensation and glide, but not so great for maintaining a good grip on the dildo, the eggs, and even myself. It’s a good job I’d positioned myself securely, safely and comfortably before I started.
Putting the egg-filled dildo on my sex stool or the closed lid of a loo helped. It meant there was nowhere for the eggs to escape to; they were forced upwards, and I was rewarded with the realisation of internal alien egg-laying fantasy. True to its name, the Kohana fucked me and posited its ova deep inside my warm, wet, tight, welcoming space. A hungry, horny slut bred by alien captors and thanking them for the pleasurable privilege.
As an aside, I would love this toy to either come with, or have the option to include, a silicone stopper for the bottom of the toy. This would help ensure that, during use, the eggs don’t fly out of the bottom instead of the top – whether you’re using it freehand, or if it moves about on whatever sort of surface you’re playing on.
What to make with the DIY Silicone Moulds?
When I took the silicone moulds from the packet when unboxing everything, I wasn’t sure what I’d fill them with. I didn’t have any silicone material of my own, no gelatine or suchlike and I didn’t want to risk using sugar-laden chocolate in my vagina. Then it hit me. I recently made DIY ice butt plugs thanks to a novelty ice cube tray, so why not indulge in a little vaginal ice play with Kohana? After all, as long as the ice is slightly hand warmed before insertion to prevent frost burn, using ice in the vagina doesn’t carry the same risks as putting ice in your ass.
Disclaimer here that I’d consider this risk aware consensual kink (RACK) – I am not saying it will be 100% body safe for you to put ice in your vagina, I don’t know your unique physiology or what your body can tolerate. I’m just saying that I can play with ice in this way personally, and very much enjoy it. If you decide to give it a go, take it slowly, and please run your hands over the ice first to remove risk of sticking or ice burns. Ouch.
I also find it exquisitely kinky to slip an ice egg inside first, before being fucked by my husband. He loves the thrill of the unusual, chilling sensation, and I love the contrast between his hot, urgent thrusts and the firm, frozen rounded egg being pounded inside me.
My Homemade Ice Alien Eggs
It was really easy to make alien eggs out of ice here at home. The silicone moulds all worked well and the icy eggs came out of the moulds afterwards with minimal hassle. I love the fact I’ve got 3 sizes to choose from; it means I can use whichever size I feel most comfortable inserting or mix them up for varied internal sensations.
I found it easiest to fill each mould through the top holes using the kitchen tap, with the freezer drawer open and ready for me to carefully but swiftly transport the water-filled tray to before leaving the water to freeze solid into the egg shapes. When the trays were full and put into the level drawer, I topped each one up using a small jug to ensure they were as full as possible. It’s worth checking them after a couple of hours, pressing gently with fingertips to see if you need to fill any of them up further so you end up with as full an egg-shape as possible once the mould is taken apart.
After leaving them overnight, the water had frozen completely and I could remove the moulds from the freezer drawer, brush off any external ice particles and lift the lids to reveal my sensationally frosty alien eggs. As an aside, if you don’t end up using them all in your Kohana dildo, they make fantastic ice cubes for your rehydrating beverage after your passionate playtime.

Summary
In case you can’t tell by now, I absolutely love my Nothosaur Kohana Ovipositor Dildo and the silicone KoXeno Eggs I use with it. The inclusion of the push rod and silicone moulds were warmly welcome, and I enjoyed the process of making my frosty alien eggs here at home, then the chills & thrills of using them in the gorgeous, twisted tentacle dildo.
That bold yet intricate design on the outer of this seriously erotic dildo provides a truly mind-blowing ride, from the moment those flexible tips tease your aroused outer area to when you’ve enveloped its huge, bumpy girth and the xenomorph beast is hatching its slimy eggs deep inside you. If you’ve ever harboured an alien breeding fantasy or you’re keen to give it a try, this is the Ovipositor dildo for you.
That said, it isn’t a toy for those who shy away from extreme kink, large toys, intense textures on those toys, or anyone unwilling to get wet and messy during solo or partnered playtimes. In my opinion, Kohana would also benefit from some sort of silicone stopper or bung for the bottom, to ensure the sublimely slippery KoXeno eggs have nowhere else to go but deep inside me during play.
There is the option to add a Vac-U-Lock suction base to your Kohana order, so I’d strongly recommend doing so.
Pros
- Stunning twisted tentacle design with bold outer texture
- Option to include KoXeno silicone eggs, push rod and mould trays
- Use small, medium or large eggs you make at home with the DIY mould trays
- Makes erotic alien breeding fantasy a vivid reality
- Body-safe silicone material
- Choose your own colour blend, size and additional accessories like lube
- Great for creative kink such as using ice or gelatine eggs
Cons
- Very large, so not beginner friendly
- Requires lots of lube and some thoughtful prep
- Messy play with eggs can be hard to manage
- I had no stopper for the base, which made it more challenging to keep the eggs inside the dildo & only pop out of the top. Solve by adding a suction base to your order

General Info & Specs
I chose the large size Nothosaur Kohana Ovipositor Dildo, in ‘Space Blood’ colouring, and the generous team sent me a large, branded storage pouch with the set that also included 6 silicone KoXeno Eggs, a push rod and small, medium and large DIY egg making trays.
At first, I felt a little intimidated by how much stuff arrived with the Kohana Ovipositor, but once I gave myself time to go through it all properly, I was excited to get started.
The silicone trays that came with it meant I could make my own alien eggs at home, in small, medium or large size, to match personal preference or specific fantasy. These DIY eggs can be made in the silicone, lidded trays from body-safe, dissolvable materials like gelatine or cornstarch mixes, but you can get creative.
As for me, I found it easiest to freeze water into the trays to create various size ice eggs, which gave a cold, intense twist to the whole experience. Running my hands over the eggs before sliding them into Kohana ensures there’s no risk of ‘ice burn’ and I keep to external or vaginal play when it comes to ice, avoiding ice inside the anal area.

Packaging & Unboxing
Like all my deliveries from Nothosaur Toys, the Kohana Ovipositor, silicone KoXeno Eggs pack, storage pouch, push rod and DIY alien eggs trays came boxed discreetly for the post, whilst the items in the box were packaged securely.
The dildo was sealed into its own transparent front, black branded rear jiffy bag, in another was the push rod and set of 3 silicone egg maker moulds, and in another was the set of 6 KoXeno Eggs. Separately packaged I found the branded drawstring top storage pouch, which is very roomy and can hold the dildo, eggs, trays and push rod all at once.
