b-Vibe Slipskin Girthy 9" Review: The Most Realistic-Feeling Sliding Skin Dildo?
Oh my gosh, b‑Vibe absolutely nailed the density of a dick tip in its Slipskin realistic dildo line.
I'd go so far as to say it does it even better than the brand it's a dupe for, at a lower cost, and with higher quality.

Purely product-wise, it is incredible in its lifelike layers: matte, grainy, skin-simulating silicone, floating movable balls, a hard shaft, a defined perineal raphe, and, of course, liquid silicone between the core and the cover for contrast.
It's firm on the inside, then it's slippery like "blood" underneath, so then the soft "skin" can slide, like it would on a gripped cock.
And I can't stop thinking about the 9" Girthy head: ohhhh my gosh, oh my gosh, oh my gosh, the silicone softness they chose is uncanny. It squishes just like a cock against my cervix. It squishes between my thumb and fingers for the visual show and yields against my lips (the ones on my face more so).
And if the tactile finish matters to you — it doesn't much to me because I tend to use ludicrous levels of lube, anyway — then yesssss, you'll like the b‑Vibe Slipskin more than the stickier Jock Real Skin formula.

Are you ready for your advanced dildology lesson?
b-Vibe Slipskin vs. Jock Real Skin 8.5" vs. RealCock 2
b‑Vibe's Slipskin dildos with sliding skin win for realism, while the Jock Real Skin 8.5" dildo wins for being polished and pretty. Mmm, that juicy, juicy head against my walls and ceiling. I clamped down and sighed just typing that again, OOOH LOORRDDT!
I thought of the Real Skin 8.5" when typing that, but to be frank, that and the Slipskin 9" Girthy are both delicious.
It squishes just like a cock against my cervix … It's trance by repetition, my focus narrowing to the sensory overload, over and over again.
What are the differences between b‑Vibe Slipskin and Jock Real Skin? In short: surface, size, and vasculature.

Surface Finish
b‑Vibe's Slipskin dildos are matte and grainy in higher resolution (oooh, the cusp of that frenulum is juicy and I want to trace it with my thumbs), while the Jock Real Skin 8.5" sliding skin dildo is more glossy and smooth (there are some pore textures, but not as much).
In other words? Consider Jock's Real Skin sliding silicone dildo prime Pacinian corpuscle paradise. b‑Vibe's Slipskin delights those deep pressure sensors and my Meissner's corpuscles for fine touch.
(My biology degree has straight up turned my granular love of cock into a fetish.)
I much prefer how the Slipskin feels against my hand, as it's less sticky — think of maybe a cock with lube that's dried up a little. It's gummy but not quite as tacky as the Real Skin surface. (Not to be confused with the much more matte dual-density formulas, which, ooooooh, feel nice everywhere, including on my lips without lube. I want to fellate those. I'd sure as hell rub them on my face.)
With lube, it doesn't matter all that much. And I highly recommend a thick formula like Wicked Jelle to stay on all those textures with little drip. We love Sliquid Sassy, but a ruggedly realistic sliding skin dildo — especially one with some girth — is beyond its specialty! Likewise, if you're choosing between GoLove and Morgasm for wall-relaxng CBD here, the latter is the clear winner.

Sizes Available
b‑Vibe's sliding skin dildos currently come in two shapes — girthy and curvy — and several sizes, ranging from 6" to 10" in length. Their girths scale up proportionally; choose what works for you. And they're all Vac-U-Lock fucking machine compatible, with a removable port plug for stability.
Realdoll's Realcock line, meanwhile, has a broader range of shapes, with size options that could generally be summed up as “they’re all big fucking dils.” Likewise for Jock's dual-density dildos.
I chose the biggest Girthy model mainly because I crave length and tolerate girth. (More on why I didn't choose the Curvy shape in the next section.)
b‑Vibe's 9” Slipskin Girthy model features 9” of total length and 8.5" insertable. At about 2.5" across the bottom of the shaft, it's basically a soda can diameter. Around the corona? About 6.25” circumference or 2” diameter.
One thrust, and I knew I'd be mindless soon.

Vein Line Quality
Jock's Real Skin 8.5" veins are straighter and more stylized. They're not as realistic, but they're also not as in-your-face about it.
And I am picky about dildo vasculature, so I should emphasize that b‑Vibe's vessels are not as obnoxious as they are in the maker's photo library. (See my photos for another point of reference.) Their apparent exaggeration was why I chose the Girthy model over the Curvy one.
Purely shape-wise, I looooove the b‑Vibe Slipskin Curvy silhouette, which, by the way, is a dupe of Realdoll's RealCock 2 Dirk. The Girthy one is more like the RealCock 2 Rockwell. (Personally, I got the RC2 Max just because its shape is more like my then-partner's cock.)
Anyway, going purely by b‑Vibe's product image assets, I chose the b‑Vibe Slipskin Girthy in Mocha because the veins were arranged in a more visually pleasing manner to me, and there isn't as stark a contrast in color. Once I saw the other b‑Vibe Slipskins in real life, though, I must admit that every swatch looks better in person.

What a shame that the RC2s turned out not to be 100% body-safe, though. Their airbrushed veins and mottled subtleties hit the aesthetic sweet spot for me. And the Jock Real Skin 8.5" sliding skin dildo doesn't really have any added pigment to the veins — just a juicy, glossy pink tip. And while that might register as flat to those looking for the most realistic dildo, I appreciate that it doesn't try too hard.
In short, "Editor's Choice" remains the label for Jock's Real Skin 8.5" due to my aesthetic preference, while b‑Vibe's Slipskin series' sensations would be more of a crowd-wower, even if not every part of the palette is for my palate. (Figuratively.)
Sensation-wise? It's perfect how the tip feels like a cock head.
How b-Vibe's Slipskin Girthy 9" Feels In Use
In literal terms, I wouldn't mind these dildos pressing up against my palate while my lips wrap around the shaft and feel every little pore.
I love fellating. But I love cervical stimulation more.
It is a testament to my fetish-level aesthetic admiration that I fixated on the form of the dildo far more than the function until this point.
Or maybe the way it feels could be summed up, "It feels like it belongs all the way inside me."
The tip swoops just the way I like, nestling in my posterior fornix.
The soft silicone's slow slides and hard banging meld into pure sensation — not registering as a piece of plastic, but rather "Oh, fuck."
But I can't do justice to it when I leave it at that, can I?
So I'll copy and paste what I live-texted my play partner as I used it.
Spicy Notes to My Play Partner
"So I'm working the shaft in. I guess I've been really tense lately and need to take my time breathing deep to open up.
“I just let it chill for a bit to get used to its presence. Once I started pushing it in OMG I was already warm and face flushed from the first thrust all the way in. The head feels so real omg omg 😭😭"
He replied, "I wish I was there holy fuck"
"This is when I would just stare at the ceiling with my eyes rolled back while you slip your finger in my mouth and sway my face side to side and say, 'Awww, look at you. Poor thing, can't even find words to tell me how that feels.'
"And I'm just panting, on the cusp of sobbing with desperate eyes. It feels like a lot. 🥺🥺🥺"
"But I think I need to sit on it and lower my weight to get it right were I want…
"I think it's 8" long and I have 6" in right now.”

“It is a lot,” he texted back.
“Yeah. It ALMOST hurts to cum on it but every nudge feels like I'm melting into just a haze of warmth and joy. Like am I even human anymore?
“And the head on my front wall 🥺🥺🥺 the sliding skin 😭 it just feels so right, like it belongs inside me.”
I sent some photos with it inside me. “I mean, look how far it split my lips apart"
The conversation got straight up pornographic from there — both our brains melting despite him saving up his cum for the weekend.
"Whyyy does it have to feel so good. I can't stop thinking about it."
"Soon you will not have to think."
My cunt can't spell 'placebo' when the oxytocin hits.
Closing Comments & Naked Neurobiology
You get the point: the b‑Vibe Slipskin 9" Girthy dildo feels like a lot because it is a lot:
- 8.5” of insertable length
- 2” across the head
- 2.5” across the bottom of the shaft
- Vac-U-Lock fucking machine compatible
It's hard in the right places while soft at the head (again, uncannily realistically so), squishing on my cervix, and remixing my insides and my mind alike. One thrust, and I knew I'd be mindless soon.
Every nudge took me deeper into ego dissolution, as I lost my sense of separation between self and other.

(You see why I love servicing my cervix, yeah?)
It's trance by repetition, my focus narrowing to the sensory overload, over and over again, hyper-focused on that cock head on my cervix. That cock head on my cervix. OH MY GOD, I CAN'T STOP THINKING ABOUT IT in the most blunt, animal brain visuals and replaying of somatic memory, like my subconscious is recalling thousands, maybe millions of times I've felt that "eject oxytocin" cue, and my conscious mind is just gone.
I'm getting wet again, feeling the veins on my fingertips and the head on my lips, kissing it.
It's not a real penis. It's not a person.
And my prefrontal cortex knows the difference once I've come down from the high.
But my mirror neurons don't know that when I play the fantasy out in my mind. Not when my nervous system is that overwhelmed by how good it feels.
My cunt can't spell "placebo" when the oxytocin hits.
