“Shh, little girl,” he growled, teeth catching my bottom lip. I fought the moan, but he circled my clit, my hips jerked helplessly against his hand. Then he pushed my panties aside and sank two thick fingers inside me. I soaked his palm, knees buckling as tremors wracked me. “That’s it, cum for me,” he whispered against my ear. I did. Waves crashed through me while he held me up, stroking gently, murmuring filthy praise that made it sweeter, deeper, more shattering than anything I’d ever felt with a woman. I’m a lesbian. I’ve always known it, claimed it shamelessly. I’ve mapped women’s bodies with my mouth, hands, loving every touch and gasp. My best friend’s tongue between my legs has made me come countless times. The only man I tried, my ex, was awkward, unsatisfying. I swore off them forever. I love women. I love my best friend. So why does this man, her father, the one I should never want make me wetter with one stroke than she ever has? Why am I aching for his cock, pushed inside me, thrusting relentlessly, filling me, ruining me in ways no woman could? Why does bending over his desk for him feel like the right thing to do?

My friend took me to her father, the college owner. One look at his body and I was lost. That night in their home, hiding in the kitchen while watching him cook, I touched myself, craving what is forbidden. Will my best friend discover my sudden addiction to her father? Will her aunt ever stop wanting me?

Mistakes? I’ve made plenty. The biggest one? Falling head over heels for Brian Lockwood—my brother’s best friend and the captain of the school’s basketball team. For years, I lived in the shadow of my one wish: for him to see me as more than just Simon’s little sister. But how could he, with Lyla, his perfect girlfriend, glued to his side? Then everything changed. Lyla cheated, Brian’s heart shattered, and he was desperate for a distraction. That’s when he came to me with a deal—a no-strings-attached arrangement where we could give each other exactly what we wanted. I saw my chance. I thought I could make him fall in love with me. But I didn’t account for how messy things could get—how keeping it all a secret from Simon would twist everything. And when Brian crossed a line I couldn’t forgive, I knew it was time to let go of my high school crush. Fast forward three years. I’m over him. Or so I tell myself. Except now Brian’s back, no longer the heartbroken boy I knew but a leading basketball star with one goal: to win me over. I swore I wouldn’t fall for him again.

When Mia hooks up with her brother’s best friend Ethan, their one-night stand ignites years of hidden love, risking family betrayal and heartbreak.

His face was inches from mine. His breath ghosted over my lips—warm, whiskey-scented from dinner and my body remembered him instantly: the way he’d pinned my wrists, the slow grind of his hips, the filthy things he’d growled in my ear while I came apart beneath him. He leaned in. I felt the pull—like gravity, like hunger. My lips parted on instinct. Just one more inch and we’d be kissing again, messy and desperate, right here in his car like teenagers who couldn’t wait. But reality crashed in. I jerked back, pressing myself against the door. “We can’t.” His jaw ticked. “Why not?” "Because I practically raised you.” My voice shook. “Because your mom is my best friend and I'm way older than you..." "I don't care" he bit out, shocking me even further. "I’ve wanted you since I was old enough to know what wanting meant. And don’t pretend like you don't feel something too." Sophie helped raise him. She was there for homework, school runs, and the lonely years when his parents were too busy. To her, he was just her best friend’s son. Years later, she catches her husband cheating on their anniversary and loses her unborn child due to the shock, Sophie spends the night with a stranger that she never expects to see again. But the stranger is Antonio — the boy she once helped raise. Now he’s all grown up. Powerful. Successful. And off limits. She manages to escape from him — so she thinks — until days later, she gets hired in a fashion company where Antonio is the CEO.

"No Chris… you can't fucking kiss me with the same lips that tasted Anna's. You can't… just leave Chris, please leave…” She screamed, her body shaking terribly. For Anna coming home meant summer nights by the lake, her mother's cooking, and slipping back into the life she left behind. Most of all, it meant Carly, her best friend, her constant, her home. And Chris, Carly's boyfriend. Who was clearly off limits or at least... he should have been. Because the moment Anna steps back into Millbrook, something feels wrong. The town is quieter. The air feels heavier. And Chris? He isn't the same boy she remembers. He's colder, stronger and dangerous in a way that makes her heart race and her instincts scream. Then come the dreams. Running through moonlit fields. A voice calling her name. A presence she can't escape... or resist and when the truth finally surfaces, it shatters everything Anna thought she knew. Chris isn't just her best friend's boyfriend. He's an Alpha and impossibly she was his mate. Torn between loyalty and a bond she can't break, Anna must decide, walk away and protect the only family she's ever known or surrender to the Alpha who was never meant to be hers. Because in a town full of secrets, some fates are more dangerous than others... and loving him might cost her everything.

After I got a second shot at life, the very first thing I did was enroll in an intensive weight-loss boot camp. In my past life, my boyfriend was always on my case about my weight. He flat-out told me he wouldn't put a ring on it unless I got down to a hundred pounds. I tried every diet and workout plan out there—I pushed myself to the edge—but instead of losing, I packed on even more pounds. Meanwhile, my so-called best friend ate cheeseburgers, fries, and pizza like it was her job and still dropped from 130 pounds to a hundred in less than a month. The second she hit that magic number, my boyfriend's head turned. They started sneaking around behind my back. When I finally confronted them, they shoved me off a rooftop. It wasn't until after I died that I discovered the truth: my "best friend" had linked herself to a weight-transfer system. Every single pound I struggled to lose went straight to her. And every ounce of fat she should have gained? It landed right back on me. When I opened my eyes again, I was back on the exact day my boyfriend gave me his hundred-pound ultimatum. With every memory of my past life intact, I couldn't help but smile. My best friend wants to be skinny, does she? Well then, let's see how she likes being nothing but skin and bones. Let's see if forty-five pounds is skinny enough for her.

When I get married to Zachary Lennor, I know that he has a younger, depressed sister who's a huge pain in the ass. On our wedding night, she suddenly barges into our room with the excuse that she's terrified of the dark. That's why she wants Zachary to sleep with her. When I get hospitalized due to my illness and need Zachary to take care of me, his sister insists that he go home to eat all three meals with her every day. Otherwise, she'll go on a hunger strike. Even when Zachary and I are on a date, his sister will call him immediately, claiming that her depression is acting up. If he doesn't go home right away, she will jump off a building without hesitation. Unable to take it anymore, I unleash my anger on Zachary's sister. But Zachary is quick to shield her from my ire. With an icy expression, he tells me, "I only have one sister, whereas I can always get myself another wife. If you can't stomach her presence at all, we'll get a divorce right now." I keep tossing and turning in bed at night, unable to sleep at all. That's when I decide to get out of bed just so I can apologize to Zachary and his sister. As soon as I walk to the doorway, I hear a familiar voice whining from the master suite, where Zachary stays. "Zach, since Samantha got so mad at me today, does this mean she's found out that I'm not your actual sister at all, but your ex-wife?" Zachary pauses momentarily before saying reassuringly, "Even if she does, it's fine. Although I do love her, I've already vowed to stay with you forever the day I married you. "So, even though we're already divorced, I will still keep my word. I won't let you go." At that moment, I finally realize that Zachary's so-called younger sister is just a fake identity. Her depression is also a big fat lie. I'm the only one who's been kept in the dark about everything in this performance. In that case, I'm not going to humor these jerks anymore.

It was the third year of my secret relationship with Garrett, my Alpha brother's best friend. Marcus laughed and nudged Garrett playfully. "You've been with that little mate of yours for three years now. When are you going to introduce her to the pack?" I pressed myself against the doorframe, my heart racing. Had my brother figured out our secret? Garrett just laughed it off. "What mate? Just some crazy she-wolf who won't leave me alone." Marcus caught sight of me and grinned. "Sage, you see this? Never pick a mate like Garrett here." "Takes everything a female offers but won't even acknowledge the bond." Just then, more of Marcus's friends arrived, and they joined in the teasing. "Your brother's right, but Garrett's had his heart set on someone for years." "What was her name again? Oh right, Aria. She's returning to the pack soon." I'd heard that name before - Aria. But Garrett had never told me she was his true love.
