This is what I needed right now. Nothing said “I’m preemptively grieving the loss of my rights” like some good ole double brother twin/brocest + orgy action.

I love the way I care so much about these four guys even though this is literally pure smut. I just want Ben and Nate to be happy and Aiden and Foster to ruin their dad’s life 😭😭 I’m so sad it’s over but you know what that means…more of other stuff. Maybe more from Release and also books from B.L’s other pen name.

Also, the content warning (?) will go down as one of my favorite book openings. You’re right, you shouldn’t do sex stuff with raccoons but definitely not for science. 😂

5 Stars ⭐
A taboo short story where our 2 "brotherly" couples find they have a lot in common 😏.
It mixes the good parts: has depraved, kinky filth with emotional sweetness. Awesome, ya? Devoured this in around 2hrs. It's MM + MM, which makes sense for the 4!

They're all going strong, lol. Aiden loves being the frat slut 🤣, Foster's protective 😁. I was happy to see aftercare 😍. A certain father shows his face here FINALLY & we get *some* family insights! I'm glad to see F+A sweet moments.

Nate+Ben's my fav, so the "I miss you" made me emotional 😭. Long distance, but a solution too, yay! The reveal bits are fun. It all culminates into a sexy climax & of course, F's the ringmaster 🤣. It's a good ending, I do wish we had gotten a time skip (Ok, it's in omnibus but I got em separately, that sucks 😭. Maybe someday I'll treat myself with it!).

Do I wish these 4 had become exclusive? Yes. But that wouldn't have aligned with F+A's kinks, ehh. Still, loved the boys!

Series Review:

I found this via bookstagram and devoured this trilogy within 6hrs on Christmas Eve! Such a perfect time, ya? 🤣 It's taboo, MM incest, with college Bros.

My short, overall thoughts:

🥵Book 1: Extra filthy, depraved, kinda dark. Very hot! THAT REVEAL UGHH. 4.5/5 ⭐.
🥰Book 2: Perfect, smutty with feels. Loved the emotional charge! 5/5 ⭐.
😍Book 3: Culmination of book 1 & 2 vibes, leads to MM + MM! 5/5 ⭐.

Series ratings: Wrote in-depth ratings for all 3 books together as it's fun to binge read!

Book 1+2 has 1st person, Dual POVs.
Book 3 has 1st person, Multiple POVs.

1) The Characters: 4/5 for F+A & 4.5/5 for N+B!
2) The feels: 😏😩🤨🥵😆😅😭🥵🥰🤭😳😗🥵
3) Sexy/Steamy scenes: 4-5/5 (yes, it's in range)
4) Levels—> Lowish-Moderate Angst;
Kinda Cute;
Some Dark (in book 1 mostly)
5) Plot & arc: 3/5 (Short, smutty, some feels!)

The final piece of the puzzle. After following two different sets of brothers throughout this three book mini series. This book brings all four of them together building bonds they never thought they needed (sexually).

- Feminization
- Fisting
- MM extreme taboo
- Object play
- Free use

Yeah this entire series gave me all depravity I needed with a nice plot, well some plot, and flow. I'd say this book was a good end to the series.

Ben, Nate, Aidan, and Foster realizing they share the same secret was 🥵

Definitely enjoyed this entire serious. The spice is just UNNNFF

My lawd. *clutches pearls*. If I thought these couples were hot separately, it’s nothing compared to when they play together. Jeebus. I actually really like the dynamic between all of them. I haven’t done anything all day but read these stories!

Admito que este fue el libro que menos disfruté de la serie, pero aun así fue una buena lectura. No conecté tanto como con los anteriores, aunque la historia se deja leer con facilidad.

I’ll admit this was the book I enjoyed the least in the series, but it was still a good read. I didn’t connect with it as much as with the previous ones, even though the story flows easily and is quick to get through.

i think i liked this one more bc both couples were in it, but there was practically no plot (which sometimes i don’t mind tbh) so it was eh. i liked that they all were together, but foster is just there sometimes and he doesn’t really do anything. i know that controlling the situation and dominance is his thing, but come on man, have some fun and join the party. also since nate is transferring to their school, i’d assume there’d be more “parties” like this which i wish we could read about

Mezclemos el primer y el segundo libro, a sus personajes, sus perversiones y dramas, y tenemos esta historia que es básicamente un relato erótico bien escrito.
Raroooo.

And when you don’t think it can get any better, we get this!?! I absolutely loved that we got more of our favorite boys from book 1&2. And let’s just say that it got way hotter than I was expecting. I love some good 4play, if you get what I’m saying!

$1.49 on Smashwords sale until 1/1/2025 along with the first 2 books.
“That's it, bitch. Moan for me. Moan for me while your cunt
is split open and spread out.”
The books opens with frat gang bang and Aiden stuffed full of multiple frat bros and a glass beer bottle. I know it sounds rough but I was crying happy tears over how the frat bros took care of Aiden afterwards with sweet words & warm blankies💙
“Good. You know I love you in a bathroom, you filthy little
whore. Actually, come to think of it, don't just drop your
trousers. Get your tits out while you're at it and then bend over
the counter and take a good look at yourself.”
After Ben enjoys the orgy he's feeling extra needy so he calls his twin Nate for some feel-better phone sex. Nate & his filthy mouth never disappoint.
I'm fisting Aidan's hair now, fucking hard into his mouth as I
listen to Nate tell his brother everything he's going to do to
him. Distantly, I can hear the wet slap of Aidan's hand working
over his own length as well.
So, what I have decided is the pure taboo gold we all deserve, is the previous referenced quote which belongs to a scene in which Aiden is warming his brothers cock while his brother is eavesdropping on a phone sex conversation between the twins. Bravo Ms. Sparrow & thank you so much.

The thing I liked about Use Me was that the twins were monogamous unlike the brothers in Haze Me but everything went to shit in this book including a 4-brother orgy😆 I can't win.

With that being said, this installment was ridiculous in all good ways🥵 Maybe the fact that the sharing hurts my heart a little prevented 5stars but I'll work on that idk. There is something about 'cest books that make me feel like sharing shouldn't be present because the connection is so pure & complete. Again, a total me problem.

You?...you should read this because it's brother-lovely and hot ;)

Own Me - BL Sparrow

This one turned the heat all the way up and then doubled it—two couples, two taboo romances, and every page dripping with tension and spice. What I really loved was how their friendships tied the stories together. The couples weren’t just existing side by side; they were woven into each other’s lives and scenes, pushing boundaries together and even sharing the stage during some of the group play. That connection made it feel even more layered and messy in the best way.

It’s unapologetically filthy, with all the dark elements you’d expect—incest, degradation, feminization, impact play, group sharing—. Still, beneath the intensity, there’s a sense of understanding between them all that made it more than just shock value.

I tore through this story in one sitting and finished with that mix of I can’t believe I just read that and I need the next one immediately.

⭐️ 4/5

This is exactly what I wanted. Combining them? UGH thank you. I'm giddily kicking my feet and screaming. They're hot apart and even hotter together and I'm even so happy that the brother fuckers found a safe space albeit sexy space with each other.

I still prefer Aidan and Foster's dynamic, and I liked that we got to see the softer side of Foster and just how much he loves his little bitch. I adore them, I wish it was longer and I'm devasted that it's over.

It's like four chapters of just smut and yet I believe that these boys love and care about each other and I love care about them. This was exactly up my alley and it's hard to find these dynamics written well enough to be good. I'm excited to read her other books.

The rest of the brothers think he means 'frat' brother. But I know he means it literally. He does this sometimes, especially when I'm at my most depraved for him. Points out that I'm not just a wanton fucking whore. I'm a wanton fucking incestuous whore.

This was such a great ending! I loved it! We get to see more of both couples and then they end up coming together 🥵 This feels like such an appropriate HEA for both couples. Definitely ended on a high note! The whole series is worth the read if you’re looking for some good spicy taboo goodness!

Pretending to be straight is hard enough. Anyone can tell you that. But pretending that I don't love being passed around like a fleshlight between my frat bros from time to time… that's a whole other ball game.

Last part of this short series. I enjoyed that each of the 4 main characters from the first 2 books got their own POV chapter. It was definitely interesting to see that Aidan and Foster's relationship just kind of developed, Aidan being the frat house hole was uhhhh something alright 🤣 The whole reveal between them and Ben & Nate's relationships was entertaining, the last chapter 🥵😏😝 Filthy, short stories, sometimes a little cute in the feels, but mostly you should be in the mood for all the spice when you read these 😂

*THIS REVIEW IS FOR THE OMBINUS*

This was such an amazing and hot af read. This is 3 stories in one with the same characters, plus a bonus epilogue. This follows Aidan and Foster and Ben and Nate. Aidan and Foster are half brothers. Ben and Nate are twins 😏. This book had so much spice, smut, kink, and hotness 🔥🔥🔥🔥🔥. I loved the relationship between the two sets of brothers. I also loved the friendship and sexy times between all four men. 🥵🥵🥵. Definitely recommend this taboo treat 😌

📚✨ AND B.L. SPARROW DOES IT AGAIN ✨📚

I swear, why does it have to end?! 😭 Own Me gave me everything I didn’t even know I needed—more drama, more steam, and so much more of these boys. The way their story wrapped up? Perfection. But also…can I have more, please? 🥺

The tension, the spice, the utter chaos of their lives—ugh, I loved every second. It’s messy, it’s wrong, it’s everything. You shouldn’t root for them, but let’s be honest, you will. 💕

P.S. I’m gonna need B.L. to drop an extended epilogue ASAP because these boys live rent-free in my head, and I’m not ready to say goodbye. 🏡💭

Great ending to the first two books! The story includes all 4 characters - both sets of brothers - (Aidan, Foster and Ben, Nate). The last chapter where they all go on Spring Break together - wowza! Loved this conclusion, although I'd be open to reading more about Zeta Mu Tau!!!
