Looks, Build & First Impressions
The Jupo-Jupo Ryujin Deep Throat is no ordinary pleasure toy. Designed by XTC Japan, a brand already known for high-quality craftsmanship, this one’s a fusion of divine fantasy and modern engineering. It’s an automated device featuring seven suction and seven vibration modes — all packed inside a sleek, black-and-red shell that perfectly fits the dragon god aesthetic.
At 12.5 cm (around 4.9 inches) in total length and with an insertable depth of about 5.5 cm (2.2 inches), Ryujin isn’t meant for full penetration. Instead, she focuses her divine energy exactly where it matters — the glans. Think of it as a “man’s vibrator”, designed to combine suction and vibration in a way that mimics the deep, teasing rhythm of an oral session.
Vibrations are usually tricky when it comes to male stimulation — too buzzy, too shallow, too surface-level. Not here. The Ryujin’s internal design transmits those vibrations deep through the sensitive head and shaft, giving real, tangible pleasure instead of a numb tingle. When paired with her suction, it feels like she’s alive — gently pulling, pulsing, and worshipping in waves.
The build quality is excellent. The outer shell feels sturdy and smooth, not cheap or wobbly. The control layout is intuitive: two buttons on top, one for vibration and one for suction. They’re nicely responsive, and each mode is indicated by a flashing light pattern, so you always know which setting your dragon goddess is channeling.
On the left side, you’ll notice a small air vent — that’s indeed the mechanism that regulates suction pressure, ensuring the rhythmic “inhale” and “release” effect. The charging system uses a magnetic USB cable (included), and with a 500 mAh battery, you get roughly 40 minutes of continuous use. Mine even came pre-charged — Ryujin was clearly eager to meet her mortal.
All in all, the Ryujin Deep Throat gives off an impressively premium vibe. Durable build, great finish, smart layout, and a design that fully embraces its dragon lore theme.
Score: 5/5
The Dragon Descends — and She’s Bringing Tech With Her.
Texture, Usage & Sensation
The inner cup of the Jupo-Jupo Ryujin Deep Throat is crafted from soft TPE — smooth, velvety, and lined with small internal knobs that gently massage your glans during play. It’s not an aggressive texture; instead, it’s inviting, plush, and built for a more sensual style of stimulation.
Setup is easy: insert the cup, apply a good amount of water-based lube to both yourself and the sleeve, and let Ryujin do her magic. I started by cranking up both vibration and suction to their max, expecting instant fireworks… but at first, I have to admit — not much happened. The vibrations felt a little tame, even at the highest level, and the sensation overall seemed underwhelming.
Then I started to move the device — slow, deliberate strokes — and that’s when it clicked.
The suction suddenly came alive, gripping with rhythmic pulls while the vibrations buzzed in sync. What felt mild at first turned into something truly special — a unique, pulsing sensation that mimicked the rise and fall of oral play remarkably well.
For a small device, the suction is impressively strong — comparable to what I’ve felt on the Syncbot, maybe a little less intense, but absolutely in the same league. And the soft, flexible cup never feels harsh or overstimulating. Even subtle motion is enough; this isn’t about brute force, but rhythm and timing.
While no toy can perfectly recreate the real thing, Ryujin certainly gets close — and she does so in a way that feels elegant, steady, and deeply pleasurable. Each of her seven vibration and suction modes brings a small variation to the rhythm; some subtle, some more distinct. I still wish the vibration power was a notch stronger, but that might come down to sensitivity — others might find it perfectly balanced.
Once I got used to it, Ryujin’s “technique” had me hooked. What started as mild curiosity quickly became full-blown admiration. The climax she delivers is different — smooth yet overwhelming, without crossing into painful or numbing territory. The best approach? Stop moving near the end and let her suction and vibration finish the job. The result is a fantastic, drawn-out climax that feels almost ritualistic.
It’s worth noting that the vent hole on the side can leak a little — lube or other fluids might escape through it. Not a big issue, but something to keep in mind during cleanup.
Overall, the Jupo-Jupo Ryujin Deep Throat delivers a surprisingly powerful and addictive experience. It might take a few tries to truly appreciate her technique, but once you do, she’ll have you worshipping at her altar again and again.
Score: 5/5
The Dragon’s Touch is Subtle — Until It’s Not.
Fitting
The Ryujin Deep Throat may look a bit intimidating at first glance — her entrance measures roughly 3.5 cm (about 1.4 inches) in width. But don’t let that scare you off. The TPE material is wonderfully soft and flexible, stretching enough to accommodate most users comfortably.
If you’re on the thicker side, it might feel snug or even challenging to enter at first. For those with truly heroic girth, it could be a bit too tight — or at least verge on uncomfortable during longer sessions. But for the majority, it strikes a great balance between tightness and comfort.
The internal length of around 5.5 cm (2 inches) is just enough to envelop the glans, which is exactly what this device is built for. In my case, the fit was spot on — snug, but never restrictive. Even as the glans swelled from stimulation, Ryujin adapted perfectly without ever feeling too tight or pinchy.
As always, lubrication is key. Use a generous amount of water-based lube to ensure smooth entry and maintain comfort throughout your entire session. Once everything’s set, Ryujin’s grip feels natural and consistent — tight enough to create strong suction, yet gentle enough to keep you in that sweet spot between pleasure and control.
Score: 4.5/5
She Accepts Most Mortals — But Not All Are Worthy.
Noise Levels
Since the Jupo-Jupo Ryujin Deep Throat is an automated device, noise is part of the experience — and something worth discussing. The specs list it at under 65 dB, which matches what I measured with a quick phone app test. So yes, the numbers are accurate… but numbers don’t tell the full story.
Let’s be honest — Ryujin isn’t a quiet goddess.
When both suction and vibration are active, the device produces a noticeable hum and rhythmic “chug” that’s hard to ignore. It’s not industrial-level loud, but it’s definitely there, and in quieter environments it can feel intrusive. I personally found the noise level a bit too loud and distracting, especially in the higher or more dynamic modes.
Using headphones (especially noise-cancelling ones) helps mask it, but you’ll still catch the faint mechanical rhythm in the background. Without headphones, you’ll likely have to crank up your video or music volume quite a bit to drown it out.
Different modes affect the sound, too — the slower, gentler modes keep things reasonably discreet, while the more intense ones can get rather chatty. If you live with roommates, family, or thin walls, this is something to consider.
Because honestly — if someone passes by your room mid-session, they might hear the whirring, slurping symphony and wonder what kind of cleaning ritual you’ve started in there.
(Technically, they wouldn’t be wrong. You are, in a way… cleaning your soul.)
Score: 3/5
When the Dragon Breathes, Everyone Hears It.
Safety
Safety is always worth mentioning — especially when dealing with automated toys that combine vibration, suction, and motion. Thankfully, the Jupo-Jupo Ryujin Deep Throat is a very safe device to use overall.
During longer sessions, the body of the device can get slightly warm, but never to a concerning degree. Inside, there’s nothing that poses a physical risk — no sharp edges, no overly strong vacuum pressure, and no aggressive tightening. The suction strength feels well-calibrated, creating satisfying pull without ever crossing into discomfort.
Of course, if you ever feel uneasy or uncomfortable, the rule is simple: stop immediately. Pleasure should never come at the cost of safety — not even when serving a dragon goddess.
A quick note for those wondering: Can Ryujin be used with the Handy?
I haven’t tested this yet, but in theory — yes, with caution. The tunnel isn’t deep, and using a full-stroke mode could cause injury. If you want to experiment, configure your Handy to focus only on upper strokes and take it slow. Safety first, curiosity second.
Score: 5/5
Her Power Is Great — But Never Dangerous.
Cleaning
The Jupo-Jupo Ryujin Deep Throat proudly claims to be “easy to clean.”
And for once, I dared to hope… could it really be true?
Yes. Finally. It’s true.
Cleaning this device is refreshingly simple. Once you’re done with your session, just remove the suction cup insert, rinse it thoroughly under warm water, and give it a quick scrub. Thanks to its super smooth interior surface, everything flows out easily — no sticky residue, no endless rinsing ritual.
You’ll still need to clean the inside of the main device, but that’s easy too. The instructions advise not to submerge it in water, as that could damage the internal electronics. Instead, just grab a damp paper towel or microfiber cloth, wipe the interior in circular motions, and repeat until clean. Dry it the same way, then leave it open to air dry completely before storing.
The whole process takes maybe five minutes total. That’s it. No awkward angles, no dismantling ten parts, no praying to the gods of hygiene.
So yes — thank you, Ryujin, for being the first device in a long while that truly deserves the title of “easy to clean.” A genuine miracle in this industry.
Score: 5/5
Finally — A Divine Gift That’s Easy to Purify.
Tips & Advice
If your first encounter with Ryujin leaves you a bit unsure — don’t worry. That’s normal. This device feels very different from traditional toys or Onaholes, and it takes a short while to learn how to best tame the dragon.
Here’s what helps:
- Don’t get discouraged early. The sensations build gradually, and once you sync with its rhythm, it becomes seriously addicting.
- Try subtle stroking while it’s running. A gentle up-and-down motion adds a ton to the experience — it’s what brings Ryujin’s “breath” to life.
- Experiment with all seven suction and vibration modes to find your perfect combo. Some are teasing and slow, others are intense and rhythmic.
- The Jupo-Jupo is great for edging. With its 40-minute battery life, you can enjoy long, slow sessions. Take breaks, pause the motion, and let the sensations reset before continuing — it’s worth it.
- Always use enough water-based lube (like OnaEki 370) for the best feel and smooth operation.
- Headphones are highly recommended to block out the noise and keep you immersed in the moment.
- Don’t forget to charge it occasionally to keep it ready for your next encounter.
- And last but important: never store it together with TPE Onaholes — silicone and TPE don’t get along. Keep them separate, and Ryujin will stay in top form.
Patience, rhythm, and lube — the holy trinity of taming Ryujin.
Pros & Cons
Pros
Powerful suction for its size — impressive pull that closely mimics oral rhythm.
Dual stimulation — suction + vibration combo creates a unique, layered sensation.
Easy setup & cleaning — removable TPE cup and super-smooth interior make maintenance fast.
Decent battery & quick charge — 500 mAh battery with ~40 minutes runtime; charges quickly via magnetic USB.
Solid build quality — durable, premium-feeling materials and responsive buttons.- Thematic design — black/red dragon aesthetic that fits the Ryujin lore without being cheesy.
Cons
- Loud in use — noticeable noise (around 65 dB) at higher modes; can be intrusive in shared living spaces.
Vibration strength could be stronger — vibrations felt a little weak for some tastes (personal sensitivity varies).- Minor leakage risk — the ventilation hole can allow some lube or fluids to seep out during heavy use.
Fit limits — tight 3.5 cm entry may be uncomfortable for very large girth; check fit before committing.
Compatibility caution — possible to use with devices like the Handy, but do so carefully (shallow tunnel — risk if full-stroke).
Ryujin rewards patience and rhythm — but she’s not subtle about announcing her arrival.
TL;DR – Final Verdict
The Jupo-Jupo Ryujin Deep Throat is a small but mighty device that delivers an impressively unique experience. With powerful suction, seven vibration modes, and a soft, textured TPE sleeve, it creates a sensation unlike any standard Onahole or male toy.
While the vibrations could be stronger and the noise level is noticeable, these are minor drawbacks compared to the overall pleasure and intensity Ryujin offers. The fit is comfortable for most users, cleanup is effortless, and the premium build quality ensures long-lasting sessions of dragon-god-approved indulgence.
This is a device for those who enjoy slow, teasing play, want to experiment with dual sensations, or are looking for longer edging sessions. With patience and lube, Ryujin will reward you with intense, unique climaxes that feel both powerful and controlled.
For those brave enough to enter her throat, Ryujin delivers pleasure fit for a god — and maybe a little fire too.
Final Rating
- Looks, Build & First Impressions: 5/5

I’ve been curious about the Jupo-Jupo Ryujin Deep Throat for a while, and I’m happy to say it didn’t disappoint. At first, the initial few minutes felt a bit underwhelming — the vibration a little mild and the suction teasing rather than overwhelming — but once I got into the rhythm, Ryujin really showed her capabilities.
This device is unique, offering a whole new and different sensation that focuses solely on glans stimulation. The combination of suction, vibration, and soft internal texture creates a feeling that’s unlike any Onahole or traditional male toy I’ve tried. I especially appreciate the variety of modes, the solid build, and the effortless cleanup — all things that make using Ryujin a satisfying ritual.
The noise level is a bit high, and the vibration might feel weak for some, but for me, the overall pleasure, intensity, and novelty outweigh these minor drawbacks. At its €/$50 price point — especially during Black Friday deals — it’s well worth picking up if you’re curious and open to a different kind of experience.
Ryujin may take a few minutes to truly reveal herself, but once she does, the mortal is left breathless — and more than satisfied.

Video Showcase
To give you an even better impression of the Lewd and Seductive Maid’s Devoted Service , I’ve recorded some short clips showing the toy in detail. From the box art and unboxing to the Onahole itself, you can see exactly how it looks and feels outside of just pictures and words. I think this gives a much clearer idea of its size, design, and unique texture.
Please note that the video quality isn’t the best, because I had to compress the videos to be under 8MB, in order to upload them here directly.
