Undercover Daddy

Rate this book
Twenty-five-year-old Alex Makowski wants nothing more than to live up to her father's legacy on the police force, but when she bungles a major drug bust she ends up placed on administrative leave. Her chance to redeem herself comes in the form of an assignment working alongside Sergeant Connor Doyle, her father's former partner and best friend.

Some of the contestants in a kink-themed charity pageant have been receiving ominous messages, and Connor and Alex have been tasked with going undercover at the event. He will be her daddy dom, and they will need to do whatever is necessary to play the part convincingly.

Connor jumps at the opportunity to take Alex in hand, and soon enough she is blushing crimson as her bare bottom is soundly spanked. But when the punishment is over she is left aching for his touch, and before she knows it she is writhing in ecstasy as her stern, sexy daddy brings her to a shattering climax over his knee.

Alex and Connor find themselves slipping naturally into their roles as their investigation gets underway, and when he takes her in his arms and shows her how a dominant man makes love to a woman, their passion is more intense than she ever thought possible. But when the mission puts both of their lives at risk, will their newfound romance survive?

Publisher's Undercover Daddy includes spankings and sexual scenes. If such material offends you, please don't buy this book.

A LITTLE NAUGHTY MIXED WITH NICE IN JUST THE RIGHT WAY

Another great story by Ms. Deane with her unique, quirky style of characters and situations that are brought to life in this tale of mystery, suspense, threats, kidnapping, and rescue. When a private BDSM group has threats made against some of the littles that participate in a pageant, the local police force seeks help from an outside force in a different town. They need two undercover cops to pose as a Daddy Dom and his little girl to keep the players safe. This story had me laughing out loud at the antics of Alex and all the things she says. She “makes wisecracks and couldn’t verbalize the correct form of an idiom.” It had my heart breaking for her as a daughter who lost her father, a highly decorated officer, and how she never felt she was good enough or what he wanting in a child.

Sergeant Connor Doyle wouldn’t be where he is in life if it wasn’t for relatives that took him in after the death of his parents, and the help of the man who became his partner and mentor, Frank Makowski. He has some hidden secrets that will come in handy when placed undercover on a new case, along with Alex Makowski. Not a stranger to BDSM, will he be able to indoctrinate Alex into the scene as they go undercover as a Daddy and little girl?

Alex Makowski feels like she never lived up to her father’s dreams. First off, she wasn’t the son her father wanted, no matter how prolific she became in sports, camping, handling a weapon, and martial arts. Then she hears nothing but praises from her father about his partner and protégé, Connor Doyle. Throw in that secretly she has had a crush on him for years, but he treats her like a kid sister, calling her Pip. For her, it is as if no good deed ever goes unpunished.

The plot will call for two cops from another town to go in undercover during a BDSM event for Bigs and their Littles. It will involve threats made against those in a pageant and trying to keep the players safe. Connor and Alex will attend and must mingle and interact as a Daddy Dom and little girl couple, including public punishments. Sometimes the truth is stranger than fiction, and as Connor and Alex interact, there is a definite chemistry present, his natural dominance will find that the strong and capable Alex has a bratty little girl side that craves submitting to him.

The story will have some intense moments, along with a kidnapping and rescue that becomes intense and for some, life threatening. When the mission is over, what happens between Connor and Alex? The story has plenty of spanking scenes, explicit sex scenes, and even a happily ever after.

*Please note, Lil Maso is also reviewing, and that review will be added asap*
.

I really don't get the fascination of grown men wanting women to dress like little girls and having them call them daddy.

Alex and Connor go undercover as they dive into the world of BDSM as a unique pageant has been receiving threats.

They take their roles seriously and become daddy/Lil girl.

I found that I liked the characters and I didn't mind the hot sex scenes those are always a winner.

But if you like daddy Dom this is for you.

Alex is always trying to be the cop she thinks her father wanted. She tries too hard which tends to get her in trouble with her colleagues. After being put on leave for her latest escapade, she has a chance to redeem herself by going undercover with Connor in the kink world as a little and her Daddy.

I loved Alex's snarkiness and her willingness to try new kinky things that she never imagined would turn her on. Conner is great as a Daddy, co-worker, friend and lover. He helps her discover her inner little and her joy of being a police officer.

If you are a fan of the movie Miss. Congeniality and kinkiness, give this book a try!

This review is from: Undercover Daddy (Kindle Edition)
I did not expect such a unique,funny and delightful
story.The chemistry between Alex and Connor was
off the charts.Alex Makowski spent her life trying
to be the son her dead father always wanted.
She never quite lived up to his standards even
though she excelled in school and at the police
academy.Sergeant Connor Doyle was Alex
fathers partner and golden boy.After Alex
ruined a sting she was partnered with Connor
to go undercover at a age play BDSM weekend.
Alex and Connor were to investigate death threats
and find the person responsible.Alex easily slips
into the role and is soon over her Daddy's knee
for one of many spankings.Connor promised
Alex father that he would take care of her always,
he is attracted to the sassy brat but will she allow
herself to love and trust Connor.This story has it all,
humor,danger,kidnapping,age play,BDSM,spankings
and a awesome love story.I loved how funny and
spontaneous Alex was.I laughed at her many antics.
Connor was a Dominant with a loving and caring side.

This. Book has everything!

Best read in a long time. I so enjoyed this book!
The writing was smooth and flowed so well I found it hard to put down. Ms. Deane also took the time to explain the feelings of the characters so I understood why they felt the way they did. Looking forward to reading more by this author.

I loved this story so much! Katherine Deane delivered a romantic, engaging and sexy tale. I loved the way the relationship developed between Alex and Connor. There was plenty of spice to heat up the reader along the way. The action was constant, and the suspense kept you guessing throughout. Not only is it a great introduction to role playing, but it is written with respect to those who enjoy this kind of lifestyle. It was sexy and passionate with sweet tender moments. Thank you for another wonderful erotic adventure, Ms Deane.

Oh wow just finished reading this amazing story. Twenty-five-year-old cop Alex Makowski and sergeant Conner were perfect together as they go under cover. They will both be put to the test but together they both have to work together in order to go under cover in an age play roles. I really enjoyed the storyline and the chemistry was off the charts hot I really enjoyed this book. I received this advanced readers copy for my honest opinion review

This book is very entertaining. Alex is still striving to be the son she thinks her father wanted and is certainly very capable in a number of areas. She is however a little impetuous and this leads her into trouble at work when she rushes in to help someone without realising that she was putting the bigger operation at risk. Consequently, she ends up working with Connor which was a mixed blessing. On the one hand she has wanted him for years but on the other hand, she harboured some resentment because she believes her father regarded him as the son he always wanted. During their undercover assignment some spanking and age play is thrown into the mix which sends Alex's emotions into uproar. There is some danger and some misunderstandings which they both struggle with. Well worth reading. I received this book as an advance review copy.

If you can suspend disbelief that two professionals would engage in this kind of relationship while on the job (I'm not talking about the relationship they were "pretending" to have), then this is a decent book. It's consensual, decently written and edited, Alex is strong and stays strong, and Connor really does care for her. Also, the dd/lg isn't so overwhelming that those who aren't into this kink would dislike it (ymmv).

The writing style is fine. But the story wasn't interesting in my view. I felt bored with it.

I enjoyed this story. I have purchased books by this author in the past and borrowed some of her books with KU.

Alex and Connor were great characters. The author gives us backgrounds on each, so that we can thoroughly understand each character. Alex is the typical kid trying to follow in her father's footsteps and earn his approval but feels that she never quite lived up to his expectations. Connor is the bright and upcoming younger partner of her father and the one that her father boasted about. Alex's open personality draws people to her (especially a certain fellow Officer). Connor's caring and protectiveness show in all of his actions.

The story follows Alex and Connor as they go undercover to find the threat at the pageant. During their research together(mostly hers as he is a Dom with experience - though not a Daddy), they are drawn to each other and get to know each other better. It is kind of a mixture of friends to lovers and discovering a Big/Little relationship type of story. But no matter how you classify the story, it was an enjoyable read and it was over way too soon. I will be reading more from this author.

I am really picky about ageplay books, but I loved this one. It was just the right amount of play. Alex was such a great strong, feisty but also caring character. Conner the perfect daddy dom. They had great chemistry together.

Spanking romances for me are a take it or leave it proposition. Some of them are just too much spanking, discipline, and age-play, all which do not appeal to me. Same with Daddy Dom dynamics. Some of them are fine, but add the age play aspect and it gets dicey. So I wasn’t sure going into this if I was going to even get through the whole book. I’m happy to report I did, and I thoroughly enjoyed it!

Alex is a female cop who messes up a drug bust. When she gets back from her suspension, she gets asked to go undercover as a little to a Daddy in a littles pageant. It seems there are death threats. The problem comes in when her ‘Daddy’ is her father’s ex-partner Connor. Despite everything, they get together and enter the contest.

They have to deal with a drama queen who thinks it’s all about her, looking for suspects, and sceneing in public. All the while feelings get involved, but are they mutual? And will Connor be able to protect Alex? Grab a copy of Undercover Daddy and find out.

I found the book to be totally enjoyable and I loved Connor and Alex together, especially the way he took care of her. Just great writing, and I couldn’t put it down!

The story is solid and I really liked how Deane delved into the world of the “littles”, it was interesting and complex.  She didn’t make it out to be anything it isn’t and the relationships between the “littles” and the Doms were always consensual and what everyone needed.  

The story is about Alex and Conner who are both cops and sent undercover to find who has sent threats against the winner of a “little” pageant.  They must fully immerse themselves into the roles of Daddy Dom and little.  This brings up a lot of unresolved issues and feeling for Alex revolving around her own father and their lack of relationship.  

The spanking scenes between Alex and Conner were downright scorching, they seriously heated the pages.  I just wish Deane had given us more of them being intimate other than spanking.  Had Connor not said they were lovers I would have thought that spanking was all they had.

The dynamic between Alex and Connor was chocked-full of sexual tension, lust, and a lot of misunderstanding.  But it was also full of love and caring that took them both stepping out of their comfort zone to discover.  I am giving it 4 Boundless Stars it was really good and I enjoyed it.

This was a good read-sexy, sweet, funny, romantic & was overall a very engaging mix. I loved Alex's intro and acceptance into this world and finding her little and that it wasn't so over the top that it would turn someone new to this genre/type of kink away :). The couple has great chemistry and are just fantastic together. It's still an ageplay but it's done in such a great way that I think it caters to such a broader fan base than many of them do. I think some of the background history got a little lengthy in inopportune times and started to draw me personally away from the story and I would have liked to see more of the current story and maybe even a little more sexy action lol. There were some editing errors but it wasn't too bad. Overall I really liked this story and would recommend reading it.
