Some time ago, I blogged about Project Ladybug, a project to create a sex toy like an alien parasite that lives within a vagina, where it steals the host’s pleasure and feeds on the emissions of her lovers.

While I was in Reykjavik, Iceland last week with the extended polycule, I am pleased to report that we were able to do a beta test of the Project Ladybug prototype…which succeeded beyond our most optimistic hopes.

Monster sex is a huge fetish, with dozens of companies producing endless variations on monster and mythological creature dildos, but my Talespinnrer and I have noticed a shocking, dare I say even dismaying, lack of monster-sex toys of the opposite sort: monsters they prey not on people with innies, but those with outies. Where are the toys that parasitize women, living within them, driving them into frenzies of need, forcing them to copulate endlessly with men, giving those men pleasure beyond imagining in order to steal their precious bodily fluids whilst denying the host any hope of satiation? This will not stand!

This is exactly the void Project Ladybug was designed to fill.

So it came to pass that after making an alginate cast of the inside of my Talespinner’s vagina, 3D scanning the cast, and bringing it into a 3D modeling program, as extensively documented in the links above (not safe for work, natch), I finally made the mold for the alien parasite, a super-soft silicone sleeve designed to fit precisely the exact shape of my Talespinner’s ladybits.

Fun fact: the project became known as Project Ladybug when my smartphone autocorrect keps changing “ladybits” to “ladybug.”

The Ladybug is a pouch of soft silicone, about a millimeter thick, that conforms to her insides and is ridged for his pleasure. It features two internal tentacles that caress the head of the man making use of the host, and as it completely covers her inner bits, it makes sure the host can feel nothing but a vague sense of pressure, but no pleasure.

Why? To keep the host in a state of extended need without relief, so as to make the host copulate fiercely with whatever male subjects happen to be nearby, of course, so that the parasite can feed.

I 3D printed the mold, which took over a day on my old and rather slow 3D printer.

The supports for the inner part of the mold ended up looking rather organic, like alien hands sprouting from the print bed to hold it warmly in a tender embrace.

Partly assembled (half the mold is not shown here), you can get a sense of how large it is and how thick it is.

Pouring the silicone turned out to be a huge hassle, because the inner clearances are so fine and there are so many undercuts that allow for bubbles to form that it actually took more than an hour to cast. I ended up doing the casting in two steps because the silicone started curing in the pot.

So it was with no small measure of nervousness, Gentle Reader, that I cracked the mold open, expecting to find a mess. Instead, the casting turned out flawless.

You can see the ridges inside the parasite, designed to offer greater stimulation for the male subject. When you look at it head on down the opening, you can also see the inner tentacles.

So enough of that, how does it work?

That’s the question we set out to answer in Reykjavik. It turns out the answer is: Rather brilliantly!

Inserting and properly seating the Ladybug proved more difficult than we’d anticipated. It needs to be pressed completely into the host, and we ultimately ended up using a pair of chopsticks for that; fingers alone didn’t really do it.

For the final version, I’ll likely design a tool for the…um, insertion.

Once in place (a process that was, by all accounts, quite pleasant for the host), it stayed put nicely.

To create the best possible simulation of the parasite experience, one that most closely replicated the aphrodisiacs the parasite pumps into the host, we both took bremelanotide (PT-141), a potent aphrodisiac that works like gangbusters on both of us, before we began the experiment.

Sex with the host was…magnificent. The final version will need larger internal tentacles, but the ridges? *chef’s kiss* The parasite absolutely, without question, amplifies the pleasure experienced by male subjects. The ridges are quite soft, and absolutely delightful on the head of the subject’s penis. What’s more, I could remain still within her and each twitch and clench, however slight, felt like a massage on the most sensitive parts of my shaft. Truly delightful.

The host, on the other hand, reported an unbearably frustrating experience, often while on the verge of tears. The host feels nothing of the subject’s pleasure. Indeed, the host feels nothing but a slight sense of pressure, even while the subject is experiencing crashing waves of overwhelming ecstasy.

There are a few minor changes I plan to make for the version 1.0 parasite. The interior tentacles need to be larger, to better stimulate the subject to heights of ecstasy. The outside portion of the parasite will be bigger, to cover the host’s clit and prevent even accidental stimulation. I may make it slightly thicker, and I plan some changes to the mold to make casting easier.

But overall, the effect is exactly what my Talespinner and I had hoped for, and I hope it opens new avenues of mad science to explore.

Alas, this is unlikely to be a sex toy I can produce in any quantity. It turns out there’s enormous variability in the human vagina (there is, of course, a PubMed article on the subject), so making these literally requires 3D scanning a casting of every individual user’s bits. I’d hoped I could maybe make 3-4 standard sizes, but no.
