160cm/5ft3 I-cup Japanese BBW Big Booty|Boobs Silicone Sex Doll S1 Miya

Unboxing, or, Why Am I Even Doing This Again?

Dragging the box inside—I remember thinking, "Why is this thing so heavy?" The UPS guy barely grunted a goodbye. Typical. The box was the usual battered cardboard (maybe that's just how they all look now), with one of those "this side up" arrows that no one ever pays attention to. There was a dent on the corner but honestly, if you’ve been around the block with these things, you know not to panic about that.

Inside? Foam everywhere. Blue sleeping bag thing—Irontech’s signature move apparently—plus air bags and foam blocks propping everything up like some kind of weird adult toy sarcophagus. Head and accessories had their own little nooks. Two white t-shirts tossed in for good measure (I never use those). And right away: neck straight as an arrow. Not a single awkward bend or crick, which is shockingly rare if you’ve ever unboxed a sex doll before.

Heads: Hard vs Soft (and Kinda Missing the Point)

Two heads in there (well, not literally two heads for this model, but I checked out both styles). The hard silicone head is…hard. Like, don’t even bother trying to kiss it unless you want to chip a tooth or something. But wow—the realism is wild. Implanted brows and lashes, mechanical eyes that stare at you like they’re judging your life choices (maybe they are). No oral though.

The soft head? Way more forgiving if you’re into kissing or anything oral-related—painted-on features instead of implanted ones though, so less lifelike but way more usable for certain…activities. It’s basically choosing between looking at something hyperrealistic versus actually interacting with it in ways that feel sort of real-ish.

Is it weird that I spent ten minutes swapping them back and forth just to see which felt less uncanny? Maybe not.

That Moment You See Her Breasts

Unzipped the sleeping bag and there they were—these massive I-cup boobs staring up at me like “what took you so long?” They looked almost too good; soft enough to squish but not saggy or weirdly firm like some dolls get. Honestly closest thing to actual human breasts I’ve ever poked on a doll (not counting TPE models).

And then there’s the body painting—veins painted on, skin texture done up with all these little imperfections so she doesn’t look plastic-y under normal light. Even her feet looked realistic (not my thing personally but hey).

Her ass—a gel-filled situation—wasn’t flattened from shipping either, which surprised me because sometimes stuff gets squished in transit and never really bounces back right.

Weight: Not As Bad As Expected

The spec sheet said 48kg with head on—which sounded nuts—but when I actually weighed her fully dressed it was more like 43kg-ish. Still heavy but manageable for someone my size; didn’t throw my back out or anything getting her onto the bed.

Joints moved smoothly except shoulders couldn’t hold a T-pose fresh out of the box—not sure why anyone would need their doll doing jumping jacks anyway but figured I'd mention it since people nitpick about poseability online all day.

Touch Test: Breasts & Ass

This part's always awkward to write about without sounding creepy—but here goes: those boobs are just fun to mess with. Soft enough to jiggle around naturally when she’s lying down; squeezeable without feeling fake; slapable too if that’s your thing (yeah…tried it). They droop sideways when she’s on her side exactly like real ones do.

And her ass? Gel magic again—it feels almost identical material-wise as the breasts so yeah grinding all feel way better than any previous dolls I've tried before this Irontech one. Best doggystyle experience yet—and I've owned more than I'd admit outside this context.

If you're wondering about seam lines—they're practically invisible unless you're hunting for them under bright lights.

Built-In Vagina & Anus Details

First impression was honestly “wow this vagina is tight” compared to TPE dolls—but after things heated up (literally) it softened nicely and felt much better mid-session onward. Pro tip: use the USB warmer included for 10-15 minutes beforehand plus lube and you'll skip past any initial discomfort entirely.

Anus has its own texture going on—felt different from vaginal canal in a good way; easier somehow? Maybe heat transfer does something here too—not sure how much science went into designing these textures but whatever they did works well enough for me.

Unexpected Tangent About Skin Color

Picked dark tan thinking it'd be closer to what you'd expect from a latina sex doll vibe—it kind of works depending on lighting? Sometimes looks lighter based on where she's sitting in my room or what time of day it is; photos don't quite capture reality here either which bugs me sometimes when shopping online since every listing looks different anyway.

Small Annoyance & A Weirdly Cute Detail

One tiny gripe—the hands articulate nicely but don’t always stay put when dressing her up; fingers flop around sometimes while pulling sleeves through shirts and get stuck if you're not careful (had flashbacks to losing Barbie shoes as a kid). But then again she gave me this accidental salute once while moving her arm that made me laugh harder than expected after an exhausting day at work.

Do These Things Ever Really End?

Honestly can’t say whether S1 Miya—or whatever head combo you end up picking—is going to change your life or just be another expensive experiment collecting dust behind closet doors after six months… But man, unboxing days still have their moments—even when I'm half checked-out mentally and typing notes mostly for myself now instead of anyone else reading reviews online late at night pretending they're doing research instead of procrastinating real life stuff again…

Guess that's about where I'll leave it tonight.
