MRLdoll Luna Review: Silicone Sex Doll Meets Video Game Jiggle Physics

For any­one who wants to fuck a twenty-​pound titty.

Luna by MRLdoll was tru­ly like noth­ing my friend and I ever fucked before — this (pur­port­ed) hyper-​realistic ass sex doll jig­gled like flesh with every thrust, spank, and grab.

“People be stim­ming smack­ing the hell out­ta that,” anoth­er friend replied to my Instagram story.

It's me; I'm people.

After prob­a­bly the 12th time reflex­ive­ly jig­gling Luna's ass as I walked past her, I said out loud, “How could I ever think I was straight?”

This sex doll made my guy friend over­think inter­course — more on that expe­ri­ence in a bit — while I under­thought my orientation.

Who are MRLdoll's Sex Dolls Made For?

Mid-​2020s AI shook hands with overzeal­ous 2000s video game tit­ty physics in the Luna sex doll's prod­uct descrip­tion of her derrière:

238 col­la­gen paths/​cm² meet 0.03μm photon-​trapping lat­tice. Refracting auro­ras through pris­mat­ic jiggle—quantum-entangled artistry beyond imitation.

As Ed from Good Burger would exclaim, “Mm! MMHM! Hmm. I know these words!" (Did I date myself with that 1997 ref­er­ence?) Consider me tem­porar­i­ly numbed to strings of words that would belong on the sub­red­dit, r/​brandnewsentence

If ChatGPT were try­ing to be me, it might say, "It's not just a brand new sentence—it’s a bal­let­ic brand new expe­ri­ence in arabesque arch­es and ass.”

An Ass Sex Doll For Titty Fuckers?

And wow, does MRLsexdoll deliv­er when it comes to new expe­ri­ences, such as a doll with lit­er­al fuck­able tit­ties — not just slid­ing between them, but a tun­nel with­in each nip­ple. “Prevent any­one from not hav­ing seen a doll's cli­max,” read the title of an r/​MRLdoll post fea­tur­ing a cum-​syringed dil­do being insert­ed inside the Big Lucy doll's breast.

I report­ed my find­ings to a friend, who then asked, “Wow. What insights has research­ing that [sub­red­dit] earned you?”

“That these are total­ly the kind of peo­ple who would want to fuck a 20-​pound boob.” I felt like I had crossed ene­my lines.

There's titty-​fucking, and then there's attempt­ing to fuck a sin­gu­lar tit­ty. And I wish I had looked more close­ly at the prod­ucts and got­ten that oth­er doll for my friend.

Nevertheless, why stop at fuck­ing one tit­ty? Why not fuck one tit­ty and anoth­er and alter­nate back and forth, while we're still in the land of wai­fu hen­tai logic?

Why not fuck a pussy or ass that feels like it was made of tit­ty? Consider that, from an evo­lu­tion­ary per­spec­tive, boobs are faux ass-​like pro­tru­sions for sex­u­al selec­tion in a bipedal species walk­ing upright. Since boobs are fake butts, this fake butt is also fake boobs, that's a fake butt again, like a leaf in the wild imi­tat­ing cam­ou­flage imi­tat­ing leaves.

Think of MRLsexdoll's Luna as “titty-​fucking plus” rather than “inter­course minus.”

MRLdoll Luna Torso Sex Doll Features

Luna weighs about 9.5 kilo­grams, or just under 21 pounds, and has two fuck­able holes. The plus side of a sex doll being just ass — I called one “spicy half doll" when try­ing to evade Instagram's cen­sor­ship — is that you can eas­i­ly pick her up, car­ry her, and watch her bounce when you thrust in cow­girl, seat­ed, or stand­ing play.

And the booty (and boo­by) bounce is per­haps what MRLdoll excels at.

Of course, they also sell dolls with both ass and tit­ties, but remem­ber that the weight of the whole unit scales with the size of the tor­so. Some are mini, while the full-​sized ones can be up to 52 pounds. That will be impor­tant in a bit when we dis­cuss positioning.

Measurements & Specifications

• 6” vagi­nal tunnel
• 5.5” rec­tal tunnel
• Waist cir­cum­fer­ence: 18”
• Hip cir­cum­fer­ence: 34”
• Hip width: 13”
• Length from tor­so to thigh: 11” 
  • 2” thigh length, in case you wan­na put short shorts on her
• Thigh cir­cum­fer­ence: 18”
• 21 pounds

Material & Care

The web­site says that the mate­r­i­al is sil­i­cone on the out­side. It feels like a 1‑inch thick “flesh” shell with liq­uid sil­i­cone under­neath for the squeez­able soft­ness and bounce.

When I flame-​tested the mate­r­i­al, it left behind pale gray ash. No oily residue, no chem­i­cal smell. It behaves like one would expect sil­i­cone to, and though I don't have a full-​on lab, it's undoubt­ed­ly a higher-​quality com­po­si­tion than the pre­vi­ous sex doll I reviewed.

That means, with prop­er care, you can keep play­ing with a sil­i­cone sex doll for years and years. A douche can help you clean it up, a UV rod helps dis­in­fect a bit more, and a dry­ing stick, well, dries the depths until your next play session.

What does the mass dis­tri­b­u­tion mean for the user?

In short, the exter­nal real­ism was uncan­ny upon first impres­sion — “It looked like a lot of thought was put into the design to look at, but not to use," my friend said.

How the MRLdoll Luna Doll Felt In Use

For this par­tic­u­lar mod­el, lift­ing Luna to bounce her on you, cowgirl-​style, would be the best way to lever­age her fea­tures. That way, grav­i­ty is doing a lot of the work for you — as long as your arms are strong enough to hold her right where you want her, of course.

When we tried mis­sion­ary and doggy-​style, we found that the doll gripped the cock and moved along with it, so there wasn't that much slid­ing in and out — it was more that the sur­faces latched on and the whole doll moved as a unit.

Think of it as a water bed in sex doll form.

Even when hold­ing it in place, the hole itself moved with the cock, unless I was using a firm strap-​on dil­do. (”I nev­er imag­ined get­ting slop­py sec­onds of a sex doll,” my friends said after I fucked it.)

Once my friend did get it in, he still over­thought quite a bit:

You'd real­ly have to love the soft­ness and jig­gle and be turned on by the wob­bling visu­al for it to be worth the cost. The eye can­dy is love­ly; the sen­sa­tion is hard­er to direct.

So yes, smack Luna's ass and grab her thighs. But also, cow­girl or GTFO. Lube up and be down to do the work.

Who Is MRLdoll's Luna Sex Doll For?

The fol­low­ing shop­pers might feel drawn to the MRLsexdoll Luna:

• “Boys who like squishy wai­fus” (my friend's words) and watch­ing ass jig­gle with every thrust — sup­port­ed by the cus­tomer review read­ing, "I sleep with my Jelly Ass beside me so I can fon­dle the jel­ly soft­ness … all the time. Just like a real woman's JELLYFIED ASS."
• Those who want a sex doll made of high-​quality mate­ri­als. Yeah, it's iron­ic con­sid­er­ing the pre­vi­ous line said “jel­ly ass,” but I assure you, this mate­r­i­al is way more skin-​friendly, body-​safe, durable, and easy to clean than sex toy “jel­ly.”
• Those who fan­ta­size about pick­ing up a part­ner — or at least ele­vat­ing their hips in cow­girl posi­tion — while fuck­ing them. The weight can add to the appeal com­pared to a small­er toy, despite the obvi­ous trade-​off of being poten­tial­ly hard­er to handle.

If the idea of fuck­ing a twenty-​pound, ass-​shaped, jig­gly tit­ty gets you hard, this toy's for you. Think of Luna's max­i­mum jig­gle and min­i­mum struc­tur­al integri­ty as akin to video game physics. At MRLdoll, fan-​servicing ani­me wai­fu meets a liquid-​filled fever cream dream.
