No matter how close twins River and Rain are, there are some things Rain knows he can never confess. Like who really broke River’s Xbox back in high school, which side of the Jordan-LeBron debate Rain actually falls on, and the fact that, lately, his dick has been getting way too excited by the thought of…

No. Fuck. It would ruin everything if he admitted that.

Then again, maybe he doesn’t have to, because River knows him well enough to guess that there’s a problem, and he’s not going to stop at anything until he figures it out.

TESTING THE WATERS is a long fall down a well-lubed twincest rabbit hole. River and Rain may think they’re just going to dip their toes in the dickalicious pool of gay exploration to test the waters, but honey, trust me: that thing is a whirlpool. It’s going to suck them in, spin them around like a Dead or Alive remix, then spit them out nine episodes later into a cum-drenched happily-ever-after of the totally taboo variety that will rock their whole damn world.

Eh. It was okay but so incredibly wordy. For such a short little novella, the interaction between River and Rain, all told, could have filled about 3 pages. And Rain didn’t even get to cum! Like, WTF? I don’t know that I liked this enough to read the second episode.

Nope. Nope. Nope. This was the opposite of hot. It was tedious with too much inner dialogue and the interaction between Rain and River was just…ugh!

How can you go from writing something as smoking hot as Free Pass to this? I didn’t enjoy her story Rent Boy in the Daddy anthology either. Such a disappointment.

Warning: panties may explode!
This exceedingly scorching hot start to the serial series is gripping, sexy and sooo naughty. There's no way you'll stop at one, so you may as well get addicted to Mama Chara like the rest of us. Stay tuned for the next edition because this book will leave you gasping for more.

re-read 9/28/21: Just a little reminder before I read the next part. Soooooo good!

Original review: Woo hoo, this is hot hot HOT! And very taboo. And I can't wait for the next installments to get more luscious so-wrong-it's-right steaminess! Write faster please Mama?!

Aaaaah!!! A serial from my favorite! My only complaint is I need more, stat. This is everything we love from this author. Obsessive relationship? Check. Codependency? Check. Taboo? Check check.

I knew going in that this was a serial but dang... the way this one ended and whatnot.

I loved this set of twins and it took me until now to get what the testing the waters title meant, hah.

Love me some twincest and this series feeds my hunger for this trope. Rain and River are 20-something twins who are both straight. Rain thinks his dick is broken because he hasn't been able to get or maintain an erection for weeks. He's been afraid to tell River but it comes out and River, as the big brother by 8 minutes, has a plan to 'fix' Rain. So of course regular readers of brocest/twincest will recognize this plot. The brothers are a hoot with lots of frat bro-speak "twins for the win, yo" and comments like "that's advanced gayness." There's a lot of inner musings on the part of each brother which gets a little tiresome but the overall tension of the story is built up well. You know what you're getting with the title of this one so the ending is not unexpected. I thoroughly enjoyed this. Found it funny, blisteringly hawt with a tiny thread of sweetness at the connection between River and Rain. This will be a series of episodes with, I believe, 9 episodes so there's definitely no HEA or HFN at the end of this first book. As the author states, the series will be a "long fall down a well-lubed twincest rabbit hole" lol! So far three episodes have been released (on Smashwords). Not sure of the frequency with which the author will release them but will be on the lookout for each.

My favorite Chara Croft are Can't touch, and Free Pass on Halloween. I really liked this I'd rank it with afore mentioned. I'm interested enough to see where the story goes and frankly I read everything by this author. The story itself felt long enough but my ebook ends at 57 pages the last chapter is for can't touch. I generally hate this(let me know what I'm buying) but since its a serial I expected a cliffhanger. Plus this author is very good about giveaways and coupons. A lot a lot of her work I have got free or discounted. I'm excited to finish the story and have zero regrets about by purchase. Another scorching hot red by Chara.

Heart beating fast as I read every single word as if I was the one talking and commanding... shivers as if I was the one listening and obeying.
Felt every decadent syllable, felt every sensation, every feeling, every desire. And the passion in the air was all-consuming.
"You", will be in such need and want.
The desperation and The Ownership... and nothing, nothing can ever overshadow the selflessness of love felt. Above everything, LOVE.

The brilliance of this authors passionate writing shows no bounds.
I'm in love with everything WATCH was and with everything this author gave to it.

Can't wait to be ravished by the rest.

DNF at 30%. It was short, true, but a wasteful, tedious writing style and immature, unlikable main characters made reaching my traditional exit point quite difficult. The author didn't even bother to describe how the twins look (by 30%), preferring instead to waste time and the readers' patience with random thoughts going through their heads. I know teenagers who are more mature and put together than these two young adults. You can summarize these twenty pages in two sentences with room left to spare. I really don't know what was the story the other reviewers read. Mine was a self-pity party, and this is just not how effective erotica works. It was the opposite of sexy. Or interesting.

What's a guy to do when his twin thinks he has a problem with his manhood functioning? Well, he takes charge and concocts a plan on the fly to help his brother out, that's what he does! River and Rain are twins with a uniquely close relationship and it's about to get even closer! Chara is literally the Queen of kinky, naughty, taboo stories and this is the beginning of another completely twisted, but completely addicting story. I can't wait to see what happens next, and knowing Chara, it's going to be deliciously wicked!

This first episode, basically the first 5 chapters of a longer book, was an excellent introduction to these twin brothers and their inner thoughts. Loved seeing how they struggled to balance their body’s needs and responses with what they expect to need and react. Seriously hot scenes, great foreshadowing, well-written, and left me wanting more!

If you like “straight” boys figuring out their same-sex attraction, newbies to Dom/sub roles, possessiveness, a mix of character development and hot scenes, plus twins, definitely give this a read!

Gorgeous and fun with an alphahole twin, River, who doesn't really care about anything or anyone but his ride-or-die who happens to be his twin, Rain. Watch is the start of this serial that will explore the twins (ahem) relationship as it twists and turns ;) through all kinds of new gay territory. We get just a taste (almost, Rain) here as River tries on his bossy hat and Rain lets him, surprising and delighting both of them. Can't wait for more of this gay(?) brother (?) twin (!) awakening!

If you love taboo this is the story for you boo! 😉
This first episode was 🔥🔥🔥. Rain has a problem…he thinks he’s broken he can’t get it up for anything…well almost anything. River is his twin his older brother (by 8 minutes) so he wants to fix everything for Rain even if it means helping him get off. I loved every filthy second of River making Rain watch. I cannot wait for the next installment 😍

For science. River is helping his twin Rain for science.

“Look at my cock, Rai,” I gritted out, already starting to pant as I thrust it through my fist. “See if you… fuck. See if you... if you like it. Watch, like I told you to.”
These twins are everything you want twins to be. Mind, body, & soul just a pair that love & trust each other. And yeah, it's 🔥.

I just finished this episode not just once, but TWICE.
If this is just the beginning, I can't wait for the juicy bits.
So I guess I'll just have to keep re reading these chapters until the next episode comes out....
Is it out yet? No? How about now?

The absolute hottest book (chapter) I've ever read. It sucks that it's serialized but that just means I've read the 2 chapters that are out multiple times. This takes spicy 🔥 to a whole new level.
