The Perfect Spiral

by Ashley Constantine

Sumner Comes First

Sumner Comes First

by Vivienne Wren

Sumner arrives at the lake house determined to keep her heart locked tight. This summer is about fixing her life, not reopening old wounds. Then Corbin walks in with that familiar grin and zero respect for emotional safety plans. He is her brother’s best friend, her first crush, and the mistake she never quite forgot. Confined spaces, shared memories, and long summer nights stir feelings she swears are buried. Corbin challenges every rule she makes, while Sumner fights the pull between comfort and chaos. Old sparks crackle with new heat, and resisting him starts to feel like the hardest rule she has ever made. Falling again feels reckless… but what if it is exactly what she needs?

Teach You, Teach Me

Teach You, Teach Me

by N. Warren

Having a massive crush on your brother's best friend is so cliché, right? But what if that best friend comes back into your orbit after six years? And what if he's even dreamier than you remembered and presents you with a deal that you simply cannot refuse? There's a girl he wants, and he's asked you to help make her his—finally. Yeah, it sucks that the girl isn't you, but he's desperate and mouthwatering, and he'll do anything you want him to do to make you say yes...so you agree. The deal is set; you teach him to nail the girl of his dreams (literally), and he'll teach you how to pick up guys. It's simple, right? Because you both get what you want? So then, how does it go so wrong?

Beneath the Blue Ice

by Donna Richards

Natasha thought she left her old crush behind when she moved away, but fate drags her back to Boston—and right into the same apartment as her best friend’s cocky hockey-playing brother. Layson has always been off-limits, but the way he looks at her now makes rules feel like nothing but fragile glass. He’s the star everyone wants, with a smirk that can melt ice, but with Natasha, something shifts—something deeper, something dangerous. She’s the quiet girl with sapphire eyes and a guarded heart, yet she makes him feel like he’s losing control. With desire sparking and boundaries blurring, can they resist what’s building between them, or will their story rewrite itself under the stars?

Mari. Marcella. Kitten. The dirty Angel of Sin… I grab the shaft of my cock as she struts into the room, white dress clinging to her curves. Her hand drifts along my shoulders, down my back, red nails tearing at my hot skin. “You’re so big,” she moans, “Please, give it to me, Beasty.”

Enter if you dare…

He was off-limits—her best friend’s brother, her longtime secret crush.

But one kiss changes everything.

Mia made a promise: no falling for her best friend’s brother. Easy... until she comes home for the summer and sees Storm again—older, inked, and every bit the heartbreaker she used to secretly dream about. One kiss ruins her good intentions. One night makes everything complicated. The boy she wasn’t supposed to want is now the man she can’t resist. Every touch is a secret, every glance a risk. But what started as a fling becomes something neither of them can ignore. Breaking the rules could cost Mia everything—her friendship, her peace, even her heart. But denying how she feels? That might destroy her.

Moonshot

Zoey’s presence pulls him into a whirlwind of heart and heat, where desire feels dangerous but irresistible. Wanting her is reckless, but not wanting her feels impossible.
