SHORT & STRAIGHTFORWARD SMUT

If you just want a stress-free and fun (and by fun I mean kinky) albeit somewhat emotionless erotica, this is it. Just putting it out there that while this is tagged as MM, the alien is a hermaphrodite, and therefore, this has a bit of heterosexual-ish sex even if they are both considered male. There’s no background nor preamble ergo no particular reason why the MC suddenly has the hots for the alien after being initially terrified of him, but he does and it just happens, jumping from fear to curiosity to all-out lust in an instant, so don’t expect much by way of plot. It’s very interesting, uncomplicated interspecies smut, that’s it. I enjoyed it for what it was, and it definitely got me curious as to the rest of the books in this series.

This is a permafree book, I believe? But I acquired a copy of this via Booksprout. Thanks to both the author and Booksprout for a chance to read this!

Kenji, exhausted from his mundane job and lonely life, seeks a moment of peace late one night when he stumbles into a nearly deserted bathhouse, hoping to unwind in the hot, soothing waters. But what begins as a routine escape quickly turns into an extraordinary encounter when Kenji finds himself sharing the bath with Zal, a powerful and alluring alien from a mysterious species. As their conversation takes an unexpected turn, Kenji is drawn into a steamy, dangerous liaison that blurs the lines between fear and desire. Kenji must navigate his conflicting emotions and decide whether he can surrender to the unknown pleasures Zal offers—or whether he should escape before it's too late. Ultra-hot and steamy human-alien MM erotica, exploring desire and surrender. Each short story explores the story of Kenji and Zal, and should be read in series order.

This is an MM monster story featuring Kenji and Zal. Kenji decides to go to the bath house after a day’s work to relax. He sees Zal across the bath and is entranced by their form. Zal is an Agorla. Kenji decides to go talk to them and things get steamy from there as Zal offers to help him unwind. Of course, Kenji says it’s not appropriate but that went out the window as he looked at Zal’s body. This is a very hot and steamy MM story featuring a monster. I received an ARC copy from the author and this is my honest review.

Way too rushed

While I often enjoy reading shorts as sort of a palate cleanser between books, this was extremely disappointing. In fact, there was nothing memorable in any way. No world building. No character development. Minimal and "yawn" smutty times. About the most positive thing I can say is that I really liked the cover! I certainly won't waste any more time on other books in this line. Disappointing and boring.

Kenji is beat. He’s had a long, hard day at work, staring at spreadsheets and analyzing data.

On his way home, Kenji decides to switch things up. He hasn’t been to the old bathhouse in ages, so why not tonight?

When Kenji sinks into the hot water, he quickly realizes that he is not alone.

The alien man is one of the Agorla, and alien race that has recently begun visiting and trading with Earth.

Zal is unusual, intriguing. Very large.

The anatomy is…not ok.

Dirty talk is bizarre af. No lube.

Apparently this author plays a lot of gender games, so this is par for the course.


I’m fucking an alien. I’m finally fucking an alien.

I'm really enjoying these sizzling hot, smutty stories from Beatrix. Such a steamy erotic storyline based around human/alien characters Kenji and Zal. I have managed to read all the series and recommend you read them in order as it really helps you get to know the characters.

I would love to have an alien come on to me, and in a bath house just makes it better. I am really glad that I was able to read and review this book and I definitely recommend it to everyone who is into alien mm encounters of the sexy kind.

If you’re looking for romance then please move along….
If you’re looking for a MM short story that’s smutty and sexy with little to no plot and includes monster anatomy, and possible mpreg then this is likely gonna entertain you. 🥰 well written, no typos. Prooooobably NSFW😳🤭.

🛸😶Original.

Kenji was leaving work exhausted.

Even though it was past midnight, he needed to relax and went to a bathhouse that was still open...

>>>>

Discovered entirely by chance and curiosity, this is a well-written and entertaining short story about a MM encounter.

A must-read for fans of this very specific genre of reading.

Pure smut

Aliens

Two sexed
Quick read

This was an interesting story it was very short like 17 pages short. But it was good otherwise. This was also a pure smut scene. They were just there... In the public bath house...

Smut for the sake of smut. I don’t think you are supposed to use a bath house like that, lol.
Not bad not great, quick read great for moments when you don’t want a ton of depth you just want to see them have a great time.

• Hermaphroditic Alien
• Tail Action
• Pure Smut, Little Plot

Kenji gets the full alien experience in one steamy encounter - tail and MM action.
It's a well written, very quick and spicy read. I enjoyed it!

Beatrix has a way with smut and this was just as hot as any of her other books. After meeting in a bathhouse and being initially terrified of Zal, Kenji and him get to talking. From there, there's less talking and more action.

I mean it's literally what it says on the tin and tbh I rate it for just telling the story of the title🤷‍♀️

A short read but nonetheless still good if you want something a bit spicy and quick to finish (reading I mean😏)

I enjoyed it but I'm basically depraved so maybe don't take my word for it!

This was interesting in the way that the alien had the reproductive organs of both sexes. Then it talked about breeding the human that had always fantasized about being intimate with an alien. It was a good quick read that had lots of spice.

Kenji went to relax after work and the bathhouse was the place to do so. But he didn't plan to meet zal and have the spiciest most fulfilling time of his life.

If you choose to read this then you won’t be surprised that an alien lizard and a human have relations in the bath. You pick it, you read it, you got the whole thing….

This is a short story with lots of steam. There are many details in the story to help you visualize everything. I only wish for a little more background in the story.

public bath.

A free read. A well, written story. Aliens or trade partners with earth so running into one in a public bath isn't so unusual, and one thing leads to another. ZAl wants to keep his little human and his human agrees.

Holy hell. This story was short, spicy, and hot. If you’re into what the story is serving, then it’s worth a read. I’d buy this story if that’s any indication. Whoo boy. Spice 5/5.
