I will be taking no questions at this time.

[Rebecca S]

Wtf? Why did I like this?

Have you ever thought "I wonder what it would be like to become a shapeshifter so my body could accommodate increasingly larger monster schlongs and have free access to multiple supernatural species to handpick for my own personally designed orgies?"

No? Me either. Until now.

Cat lives an unful"filled"ife with these basic human schlongs. So when she is given an offer she can't refuse in the name of "Science!" she jumps head first into the opportunity. She is VERY eager to "test" each and every monster and can be very vocal and demanding. *You go Glen CoCo*

This book is 90% Smut. 10% story. And 125% "WTF did I just read?"

Read it. Just Do it. Someone else needs the image of a Centaur schlong going quite literally in one end and out the other, without killing anyone. YOU'RE WELCOME.

Science, Monsters, and Zero Respect for Anatomy.

Test Subject is easily one of the most ridiculous, entertaining things I’ve ever read, and Tami (the author) is genuinely hysterical. Her humor is so sharp and unhinged that I kept laughing mid-chapter like, “There’s no way she actually wrote that… oh wait. She did.” ("I feel like more cum than girl" is a personal fav lol)

The pacing? Impeccable chaos. Every door Kat opens is a new “surprise biology lesson,” and you truly never know what creature is waiting on the other side. The escalation is insane.

The final boss structure is honestly brilliant: she has to go in order because her body literally cannot handle skipping levels. Door 1 preps her for Door 2, which preps her for Door 3… all the way up to the Big Bad at Door 10. It’s like a monster-sex training regimen. Progression-based peril. I respect the vision.

And Kat is just out here doing her job like a pro. Clipboard in hand. Safety protocols ignored. Body being bent, stretched, and shape-shifted into configurations that aren't medically recognized (what do you mean she's being impaled and loving it?). Yet she stays committed to the work and making a difference.

In short:
If you want something funny, fast-paced, a little feral, and unlike anything you’ve ever read - this is your book.

idk why i spent my morning reading this but here we are

[Katrina (Catching up on Reviews)]

Ummmm..... This was smut with monsters. Do not know why I read this, but I did weirdly like it. Cat Woods accepts a mysterious, high-paying job collecting samples from supernatural creatures in an underground lab. As she explores the strange experiments, she finds herself drawn deeper into a world of danger, curiosity, and unexpected attraction.

Whichever angle you look at this, it's fucked up - but yea it did cure my inability to read a line.
There was smut with just anything; a dhinni, a dragon, a werewolf, a pixie, a minotaur, a monster jellyfish, A STONEMAN, 🐲🧞🗿🐙🐺

I haven't read a single line for the past two weeks with how swamped up I am with my studies and job.

So yea, this is a wild read. Excuse me while I go find out, how a scientist who was supposed to draw out blood from 10 mythical creatures, but end up having the smuttiest sex WITH ALL OF THEM..

[Kimmie Morgan]

Monsters and spice? What more does one need?

When I started, I had no clue as to where this story would end up. The writing and characters kept me engaged.

There is a plot to go along with the spice so for those that need story, it's got you.

I was reluctant to start this originally but eventually, after seeing so many others talking about it, I broke down and read it.

No regrets.

[Keandra Guischard]

Read it!!!!

This Is one of the best off the wall smut I’ve read in a while. The writer is insane! How did she even think about 90% of this stuff! I couldn’t imagine half! The creativity knows no bounds. It’s a very good read if you’re into taboo, monsters, magic and sexy time 😮‍💨!

The writer wasted no time and jumped right into the plot! 10/10 HIGHLY RECOMMEND!

[Jacquie Kerr]

This book was unhinged and I loved it

this book was absolutely ridiculous, but why did i kinda like it… this lady scientist gets a new job fucking monsters to collect their semen to hopefully procreate a new species that’s becoming extinct? under the guise of collecting blood samples by her boss, she goes into each cell and gets fucked by a werewolf, centaur, ogres, pixies, djinn, A ROCK, and a dragon… this made me laugh so much and i loved it. truly a ridiculous masterpiece. it was so cute when she made des have everybody live in the extra magical door bc she understood was lazarus said by “it’s a prison”. she’s now a dragon mom and essentially has an eternal life to procreate more dragon babies with des. this was lowkey so cute except for that scene where she almost died by that water blob, but hey 🤷🏼‍♀️ at least des had his hero moment and killed it.

[Jiska]

Read this book for shits and giggles since I had already installed the app for another story.

This is one of the most ridiculous stories I have ever read, but for some reason I kept reading because I too was curious what kind of insanity would be behind the next door.

The writing wasn’t great, plot was very predictable and basically kept repeating itself. But it was short and was fine to kill some time.

[Emily Town]

That’s my fault for having eyes. And the internet.

3.5⭐️

This one was… interesting. For lack of a better word. Definitely worth the read. I really enjoyed most of the smut except for that one wtf moment. If you read this I’m sure you know exactly what I’m talking about.

[Erika cintron]

hot and erotic

Couldn’t put it down. The storyline is great and the relationships even better. Must read. Absolutely worth the read. I’m sure I’ll read again.

[Tessa]

I first caught wind of Test Subject back when it was exclusive to Galatea, released chapter by chapter, and I was unbelievably excited when I discovered it had been compiled into a full ebook. I’m a monster lover through and through, and I had a really good feeling about this one from the start. Monsters and spice are two very happy trigger words for me, and this book delivered on both in spectacular fashion.

I was sold immediately on the premise alone:
“10 doors. 10 monsters. 10 sessions of interactive data collection.”
SIGN ME UP. LET’S GOOOOOOOOOOOOOO.

An erotica that boldly shouts “for science!” as its driving motivation? Honestly, kudos. This is easily one of the most unhinged and genuinely entertaining reads I’ve had, and a huge part of that is the sharp, self-aware wit throughout. Cat’s inner thoughts are hilarious, feral, and weirdly relatable given the circumstances. The writing is solid, the monsters are imaginative, and while some don’t get much “screen time” (some of them aren’t exactly sentient), the ones who do absolutely make it count.

I’m a naturally curious girl, and I couldn’t wait to find out what was behind each door and what kind of monster Cat would be “studying” next. Reading this was an absolute blast. The novella strikes the perfect balance between plot and copious amounts of… spice. From start to finish, it had me in a chokehold; sometimes literally, just like Cat herself.

I was fully invested in the end goal of Cat’s data collection: helping the last and largest monster repopulate because he’s the final member of his species. The open/shared relationships that develop along the way are surprisingly sweet and feel intentional rather than gratuitous. And the progressive, video game style “boss” structure? Genius. Cat works her way through each door, leveling up monster by monster until Door 10: the final boss. The only way to be properly prepared is to go through the full gauntlet and let me tell you, the size prep training is NOT playing around.

The fact that Cat starts going feral for her boss before she’s even halfway through the doors is absolutely unhinged behavior. Girl, what do you MEAN you want him on top of everything you’re already getting? Greedy. Shameless. Relatable. Because honestly? If I were receiving maximum-level orgasms and elite training like that, I’d be feral too.

Special shout-out to the sheer creativity and imagination on display in this book. The fantastical anatomies, the outrageous scenarios, and especially the cleverly collected and crafted "potions" used to make it all possible were both inventive and wildly entertaining.

This book knows exactly what it is, commits fully, and has a blast doing it, and so did I.

🔥 BOTTOM LINE: HIGHLY RECOMMENDED 🔥
If you love monster erotica, unapologetic spice, creative setups, gaming-style progression, and a heroine who leans all the way in to the madness, Test Subject is a must-read. Unhinged, hilarious, inventive, and deeply entertaining, this one earned every single one of its five stars.

Overall, Test Subject is unhinged, extremely spicy, and self-aware in the best way. If you love depraved monster sex and a heroine who fully commits to the madness, this one is absolutely worth your time.

[Jennifer]

This was slop… I knew it was slop but I read it anyway.

[HW]

The definition of monster smut - this is 1% plot and 99% massive penises. This book has made me realise one can ALWAYS be MORE imaginative - for example, there’s a chapter called “The Impaling” and I cannot over-emphasise how literal this title is. Unapologetically I would read this again 😂

[Morgs]

I will not be taking any questions at this time about this book

[Kat]

it is what it is, written hentai at its best 🤣🫡

[Sarah Cupitt]

i think i have notes on my phone somewhereeee???
i forgot i was meant to be taking notes again
what the fuck did i just read

some notes:
- so we're not talking about that physical exam or
- invisible hands isn't something I've come across before
- what is mr sire cause he's not human, vampire? based on the name
- “I…I feel at home,” I whisper, shocked to say it out loud.
“You seem surprised about that,”
- WAIT HE'S A DRAGON THAT WAS NO MY GUESS AT ALL

funny:
AHAHAH MAN HOW DID YOU COME UP WITH WRITING THIS
“Oh, your cock? You call it fuckknife?”
- I’m not totally sure whether it’s a dragon or a wyvern

tension:
- “Can I decline?” I ask.
“Of course,” he says. Then he leans in a little closer, adding, “But I have
a feeling you won’t.”
- My breath comes faster, and he reaches for my neck, pulling me back
against his chest
- “So… I am a subject as well?” “My most promising one, yes.”
- I like the sound of him calling me his subject .
- “Do it.” He seems startled at the fervor in my voice. “Watch me.”
At that, a tiny grin appears on his mouth, just for a second. “Always.”
He takes my hand, and like in those old movies, he kisses the back of it
to say goodnight.
- “I know what’s getting you off”—he bows down a bit—“and that’s the
thought of the boss fucking you, isn’t it?”
- “It is one of the toughest things I’ve ever done, to resist you.”
“Well, good to know,” I grin, but he looks into my eyes, serious.
“Maybe one day…” He extends his hand toward my face, but pulls it
back again and clears his throat.
- “You do not know how badly I want to be the cause of those sweet
screams, and the way your body twitches. I can’t stop watching on the
tapes,” he says.
I feel my pussy getting wet again. “But,” he cautions, making no move
toward the cupboard, “I fear for your life if you take on Number Eight too
rapidly, without a chance to rest first.”
- “ I want you to be comfortable and content. I need your full
consent to be able to do this, and the last thing I want is to hurt you. ”
- “May I kiss you?” he murmurs.
“You may do anything you want with me,”

smut:
28 and 30
- I want to eat him alive.
- I heard your splatting for a long time yesterday. Without being
able to be the origin of it. So be a nice girl and…obey
- “Beg. Beg me to take you, to release you.”
“Please,” I moan, running my hands up his legs, “fuck me. Fuck me
hard and do everything you want to me.”
40 onwards
54
97
- It seems as if
it is me, completely consuming me. There is nothing left of me
123 onwards
anymore; I am all him.

4 UNHINGED, WEIRD, MONSTER SMUT ✨

I knew this was going to be crazy but I was actually shocked at some parts. 😳🫣🤣 I’m still not sure how I feel because my brain is trying to wrap itself around the crazyness that I just read. It was weirdly arousing, wildly creative, a little cringe 😬 from some of the things she had to do/ endure, and very very wet. Like monster fluids galore!

It’s just the type of weird crazy stuff I love to read bc it’s so outlandish that it’s genius! I mean…it’s basically the most unhinged depraved prepping process ever 🤣

I feel like more thought went into this than people think. Like the way the FMC had to adjust on a dime to communicate with each subject, the logistics of the anatomies…👏🏼👏🏼

It made a lasting impresssion so for that, 4 fold stars!

[Cindy]

What a spicy 🥵 ride this book took me on!!! This was absolutely nonstop from the beginning to the end. I only wish the second book was available on Amazon. This was my first monster read and boy did it not let me down. It left me absolutely speechless. I figured Door 10 out as soon as I started reading it but I was giddy with the anticipation to find out what happened. I was not disappointed!! If you like your Novellas scorching hot this is definitely the read for you!!
🌶️🌶️🌶️🌶️🌶️

[el.]

eterogeneo, ma non in senso buono.
stile schizofrenico, ho smesso di farmi domande dopo le prime righe.
ogni capitolo lascia la sensazione che manchi sempre qualcosa, soprattutto una ragione per esistere.
