Sideline Sins: A Beckford U Age Gap Romance
Leni Hart is no stranger to sexual betrayal. But she’s worked hard to reinvent herself—and take back her power—within the walls of her cousin’s sex club, Euphoria.
An adorably awkward older masked man has her throwing caution to the wind, taking sex outside the club as they embark on a hot online-only relationship. Behind the mask is a man who is three kinds of off-limits, but ignorance is bliss, especially when he loves to worship at the devil’s altar.
His divorce finalised, Ethan Rourke reluctantly agrees to join his best mate for a celebratory night out at the exclusive sex club, Euphoria. Even with his identity masked, he’s out of his element, but finds himself drawn to a young devil, who presents him an offer he can’t refuse. No-strings-attached phone sex—a perfect distraction from his failed marriage. It seems too good to be true.
When the two come face-to-face on campus at Beckford University, they realise just how wrong their attraction to each other is …
They should be sidelining their relationship, but is the temptation to explore more of each other too hot to ignore?

WOW another amazing book by JL.
I had trouble putting this book down it was so good. The tension between Ethan and Lina was so good you felt like you were there with them.
I can’t wait to read book 3.
Age gap, professor and student, masked sex club, sports Romance, sexting what more cookie you ask for.

I don’t even know how to find the right words..
I shouldn’t be surprised by how much I loved this book. After reading Offside Hearts, I knew the whole Beckford U series was going to be amazing.
But still.. Sideline Sins blew my mind and stole my heart. The story of Leni (Willow from Offside Hearts best friend) and Ethan is so beautiful.
Once again we start with the Masked S€X Club Euphoria, where the MCs engage in some voyeurism, followed by S€XTING and Phone S€X, without knowing who the other really is.
When it’s discovered that not only is Ethan a professor at the University Leni attends, but also her ex boyfriend’s father… well things get a little more complicated. But the way these two come together, their chemistry and passion is insatiable. They truly bring out the best in each other and I thoroughly enjoyed watching them fall inlove. Whilst some of the themes were heartbreaking (check the trigger warnings please!), the overall story was really beautiful and deliciously spicy.
I loved everything about their story, including the Epilogue that left me with such a huge smile on my face.
Highly recommend if you love the idea of - Age Gap, Ex Boyfriends Dad, Student/Professor, Healing from Trauma and Naughty times had over the phone ❤️🔥

Firstly thank you Jennah for letting me arc read Sideline Sins as damn girl you really had me hooked on that book. I literally couldn't put it down. I absolutely enjoyed it so much. I am so grateful to be a part of your team, gorgeous lady.
Where do I begin with this one, like damn this book absolutely hooked me. I really enjoyed Ethan and Leni's story. This book had me giggling and tearing up throughout this whole book. Like damn these two have absolutely amazing chemistry and the banter and cheeky moments between them. This book was absolutely fire 🔥 and omg the spice you can't forget that at all 🥵🥵🥵. These two met at an exclusive smexy club while wearing masks and they had no idea that things would go from just a casual thing to being way more and developing strong feelings for one another. These two characters deserve happiness and love for each other. They are absolutely perfect for each other.
Tropes:
age gap
college soccer
voyeurism
sexting
ex-boyfriend’s dad
masked sex club
phone sex
professor x student
If you want something that is steamy and well written romance then add this one to your TBR as holy moly I am still reeling from reading this one.

I loved everything about this book! I couldn't put this book down, loved reading Leni and Ethan's story and was a great book to follow the prequel (Offside Hearts).
So glad the books in this series are rapid releasing, because they just have me wanting more!
I really enjoyed getting to know the characters, the story flowed so well and had me kicking my feet at parts. The ex boyfriends dad as the MMC had me waiting for how it would all pan out, and JL Skye did not disappoint!

I truly fell in love with this couple and emerged myself so much in their story.
Leni and her traumatic past learns to love again with Ethan - she loves an older man but wasn’t expecting him to be her Ex’s dad!!
They meet at her cousins s$x club on one of the monthly masked nights not realizing who they are until later in the story.
This is a very hot and sexy read with trauma and a HEA.
4.75⭐️ 4🌶️

Leni and Ethan are just…. Eeeekkk I just love them.
From the healing they bring each other and the acceptance of one another pasts just make them a beautiful couple.
If you enjoy a good age gap, professorXstudent relationship, masked sex clubs and last but not least ex-boyfriends dad tropes then you are in for a wild ride.
Hold on tight and welcome back to Beckford U

What a book. I loved every minute of Sideline Sins.
Ethan and Leni are the absolute best. I loved watching them both grow and overcome their insecurities. They are so many little moments that melt your heart.
Leni is independent and strong and knows what she wants and watching her help Ethan find himself is beautiful.
Ethan is a little lost after getting divorced and is trying to navigate his way and see a new future. It's fun and witty with just the right amount of spice.
I can't wait for more in this series!
