Finally, Toy’s Heart are out here exploring some real cyberpunk-themed possibilities with the release of their smoothly titled Jinko… binko… kaku… see?

Forget Blade Runner, Ghost in the Shell or Garfield: A Tail of Two Kitties all dealing with the issue of a worldwide lasagna crisis – Jinkoukakusei is all about the eternal question most have been too afraid to ask.

“What if a girl was made in a big green tube?”

Or something along those lines anyway. I think it’s dealing with creating a ‘new type’ of synthetic human sex slaves who just so happen to have VIOLENTLY JAGGED vaginas? Perhaps some stalactite were mixed in with the DNA to spice things up.

Seems like a plausible tube-related thing The Animatrix should have covered instead of man falling over and breaking his leg, but it’s all good. The future is now.

– Unboxing / Presentation –

If you squint you might be able to see the CAT HAIR. This does not come with the onahole, it is sold separately. Jinkoukakusei does however come with a little bottle of Moisty lube, and that’s always nice. The future might be about drinking green tube water, so you’d better appreciate what simple joys life still has right now.

Do you like how these photos all have vastly different lighting despite being taken seconds apart? That’s a little secret hey. Bit of computer magic. Touch of the ‘ol ‘these photos looked like shit so I tried to salvage them with auto adjust and called it a day’.

So Jinkoukakusei is kinda on the smaller side of things (or maybe I’ve just been used to long bois with recent reviews), measuring in at just under 13cm. The actual usable length of the tunnel is even smaller at like 11cm.

Probably won’t be much of an issue once you see what it’ll do to your head alone, although I’m still not really sure why Toy’s Heart have priced this onahole so high. It doesn’t exactly ‘look’ like a $50 USD dick sleeve, you know?

… That said, most retailers seem to be dropping the price now. Perhaps Toy’s Heart took the AAA video game route where day one buyers get fucked.

But thankfully the material feels incredible to the touch, which is typical of just about anything from Toy’s Heart. Their ‘Safe Skin’ work continues to deliver a wonderful mix; silky smooth yet still offering a slight coarse texture to keep your grip from slipping out the window. Also no smell to it at all.

Visually this is also quite nice considering Toy’s Heart typically go for a more uniform, generic look of a rubber tube blob. Here there’s some actual detail including a tiny little decorative anus. Lovely. Slap some frosting on top and you could submit it to a fancy cake competition.

Let’s take a look insiiiIIIIIIIII-

Fuck me. The tunnel on this thing looks like death itself, and that’s exactly why I was so keen to check Jinkoukakusei out. Everything is so CHUNKY.

One extra fancy detail here is that Toy’s Heart have set it out in the shape of a butterfly, which you can soooorta see if you put your face right down there? This was too difficult to get a proper photo of and none of the offical promo shots do it justice either. This sketch is about as close as you’ll get.

Extra points if you fuck this while listening to that amazing dumb-shit Butterfly song that dominated DDR and cheap toy phones. Hell, use all those things at the same to ascend.

– Feeling –

Sure enough, Jinkoukakusei hits hard right off the bat. The entrance itself delivers a minor squeeze across your head, but whatever pleasurable sensation from that is instantly obliterated by a strong crushing grind. With no breathing room as such (to appreciate life etc.), this tunnel is a wildly aggressive time from start to finish.

It ain’t exactly pretty in there, but Toy’s Heart have gone for pure hardcore stimulation. There are six raised strands within the infected clusterfuck of grooves which guarantee at least a few of them are always going to be digging into your cock. There’s one that’ll snugly rub the underside of your shaft every time you thurst in and maaaan. MAN.

This seems to work best right around the mid-point where all these strands meet before leading into a tighter end zone. You’re REALLY gonna feel this part just smashing across your head with each stroke – like a tidal wave of stale bread which has gotten to the curious point of being immune to the actual water in said tidal wave.

The end zone itself offers some relief despite being the tightest part. The textures are more subdued here – but again – the second you pull back out from it you’re gonna get strangled all the way down.

However during my scientific studies with this onahole, I’ve found that the first few minutes with this can wildly vary depending on… something? Not sure, I’m not a scientist. Either way yeah, there were times where it’d act like a wind tunnel and go fucking mental with suction for a while.

I could see the entire thing inflating on the way down and then forming a second skin over my dick on the way up. This didn’t exactly change much in terms of feeling, but it did make the onahole super loud in a real obnoxious kinda way. Sometimes a noisy onahole can add to the experience if it has a sloppy kinda soundtrack goin’ on!

This one does not. During these moments it just sounded like someone fisting a roast chicken whilst making popping sounds from their cheek. Very uncomfortable for everyone at the dining table.

Mostly Jinkoukakusei is fine, although it’s still louder than an average onahole during use.

Overall, Jinkoukakusei is a pretty relentless wank. The tunnel is a chaotic mess of full-on stimulation designed to push, pull and everything in between. It’s great for those times where you’re simply craving something to get you off hard and fast. Fantastic for morning wood especially. No time for relaxing masturbation, just angry NEED TO CUM AND GET OUTTA BED masturbation.

Extended sessions however proved to be a bit too uncomfortable for me. Having your dick smashed to bits is great (?) in short bursts, but when you subject the poor thing to it for long enough, things get… tender. A few times there it left my head feeling so wrecked I could barely even pull back out after cumming – every little ridge was like a dagger.

But yeah, when you’re hard as fucking diamonds and just looking for something brutally aggressive to bounce on your cock? Jinkoukakusei’s got you sorted.

– Cleaning –

No issues here, which is surprising considering I thought for sure all the deep ridges would be a pain in the arse to dry. Just run it under a tap and give it a gentle wipe with a microfiber cloth. Should be sorted. Safe Skin material tends to dry off pretty quickly.

– Summary –

Jinkoukakusei packs an absurd amount of punch for its size. Just fucking NON-STOP high-level stimulation with six major pressure points running down a tunnel littered with like a hundred bajillion deep ridges. Strong and often overwhelming. Great for when you want to get off quickly, but longer sessions might end up tenderising your meat into oblivion.

The onahole can get rather loud though, so be wary if you live with others or don’t want to get caught cumming in the library. Again.
