170cm/5ft7 F-Cup Japanese Silicone Sex Doll – Heidi: A Real-World Dive

I’ll just say it—nobody tells you how weirdly normal it starts to feel, shopping for a full body sex doll online.

I mean, honestly, the first time? It’s all nerves and browser tabs and a bit of “what am I doing?” But by the time you’re comparing specs like 170cm (5'7") versus 168cm, or weighing up whether an F-cup is too much (it isn’t), it’s almost like ordering a fancy chair. If you're exploring japanese sex doll options, you'll find plenty of options worth considering. Except… not.

Anyway, this is about Heidi—the Lusandy Doll that’s been floating around on those forums since February 2025. She’s marketed as a Japanese sex doll but with blond hair and these very not-Japanese F-cup proportions. Go figure.

The Weight Thing Nobody Mentions

Here’s what surprised me: she’s heavy. Like, really heavy if you’re used to those smaller TPE dolls or whatever. They list her at 36kg–40kg (that’s roughly 79–88 lbs), which doesn’t sound terrifying—until you try moving her up some stairs after work when your energy is already shot.

You don’t think about logistics until you have to. Getting her out of the box was practically cardio.

Still, there’s something reassuring about the heft? Makes her feel more real than those hollow-feeling budget models under $1k. Not saying that price means everything but… above $2500 does buy you some realism in silicone.

Customization: More Than Just Hair Color

The custom options are where things get interesting—or overwhelming, maybe both. You can pick everything from eye color to nail polish shade; even little things like teeth shape or freckles if you want them.

I went with blond hair because it felt less cliché than black, though I guess that makes her less “Japanese” technically—but who’s policing fantasy? There are Asian sex doll purists who prefer classic looks; for me, mixing styles felt right.

There was also this free $205 kit offer when I ordered—a bunch of extras like cleaning stuff and lingerie tossed in—which felt nice but also kind of gimmicky? Still took it though.

Big Breasts vs Medium: Reality Check

Let’s talk about the F-cup thing for a second. Marketing calls Heidi a big breast sex doll but honestly—it lands somewhere between big and medium in person. Maybe we’ve all become desensitized by Instagram models or something?

Not disappointed exactly—I remember thinking they looked more balanced than cartoonish once she was set up in decent lighting.

Living With Her: Odd Moments & Unexpected Details

Setting up Heidi for the first time felt stranger than expected—like introducing someone new into your space who won’t ever talk back (but somehow still changes the mood). Her skin texture is surprisingly realistic; silicone has come a long way since those shiny mannequins from years ago.

Sometimes I’d catch myself glancing over while binge-watching shows—just because she fills out hoodies better than half my exes did. Weirdly enough, having her around made my apartment feel less empty during winter evenings.

One thing though: joints creak sometimes when posing her arms or legs—not loud but noticeable if you’re sensitive to little sounds at night.

The Price Tag Dilemma

Over $2500 isn’t pocket change—even if they throw in that free kit. For someone looking at an entry-level lady sex doll or just curious about trying one out… might be overkill?

But then again, there aren’t many options over 170cm/5ft7 with this level of detail unless you go custom—and most cheap ones just look uncanny valley-ish up close anyway.

It stings at checkout but feels justified once she arrives (especially compared to plastic-y competitors).

One Random Tangent About Storage

This part nobody glamorizes: storage is awkward unless you’ve got space set aside—a closet works if she fits standing upright (mine barely did). Some people use beds with drawers underneath; others just leave them sitting dressed up as roommates-in-disguise when friends visit unexpectedly… which leads to its own stories I probably shouldn’t share here.

Is It Worth It?

Well—

If what you want is a Japanese silicone sex doll that checks off height (over 170cm/5ft7), has believable curves without going cartoonish, and actually feels like something built to last—not just look good for photos—Heidi holds up pretty well against expectations. She blurs lines between fantasy and reality in ways I didn’t quite expect before owning one myself.

Still figuring out where all this fits into daily life—but maybe that’s part of why people keep coming back for more variety each year. Or maybe it’s just me getting used to oddities faster than most folks would admit out loud…
