“Daddy… Fuck me daddy… I know daddy wants my pussy…. Yeah daddy harder… Oh..” I moaned tightly, biting my bottom lips. “So close.” I whispered, twirling my other hand on my breast, pinching and swirling my thumb against my dark buds. It was fucking sweet having pleasuring myself but I wondered what it would actually feel like having daddy’s cock inside of me instead. My eyes had immediately seized upward, and my hues widened with shock, snapping at the sight of my father figure who stood unwavering at the door. My heart skipped a beat that I swallowed harshly having pushed the words out my mouth. “Daddy….” my eyes leaned on him, watching as his dark shadow loomed further inside my room, and he pushed the door closed from behind with my breath which had halted. My leg involuntarily squeezed themselves to together, and another pleasure weaved its way into my body, maybe it was actually due to shock. What was he fucking doing here? “Princess where you fantasizing about me?” *** Roses weren’t red, neither were violent blue to me, all I wanted was pleasure but it all went too far….. The moment I saw how gracious my stepdad appeared, I had made it my mission to seduce him. Unfortunately what I didn’t know was that I was a naïve nineteen years old who was being used. He turned to a monster, and he made it his own life mission to torment my existence.

When seventeen-year-old Willow Hayes moves into the remote Thorne mansion with her mother's new husband, she expects awkwardness - not a supernatural war for survival. Her stepbrother, Kael Thorne, is the arrogant king of Crestwood High and heir to a secret werewolf Pack. But when their eyes meet, an ancient Mate Bond snaps into place, marking Willow as the one person who can prevent Kael from succumbing to the deadly Feral Shift - a state of uncontrolled rage that means death. The problem? Kael's father, Alpha Marcus Thorne, sees Willow's humanity as a fatal weakness that endangers the entire Pack. His rival, the brutal Darek Ironfang, sees her as the perfect weapon to destroy Kael's claim to leadership. And Sierra, Kael's scorned ex-girlfriend, will stop at nothing to expose their forbidden connection. Caught between werewolf politics and deadly Pack law, Willow must transform from invisible high school student to strategic mastermind. As Kael faces three brutal Trials to claim the Alpha title - the Blood Hunt, the Leadership Rite, and the Ritual of Dominance - Willow becomes his secret weapon: the Obsidian Anchor, using their psychic bond to control his Feral instincts from afar. But the bond demands a terrible price. Each time Willow stabilizes Kael's wolf, she risks fragmenting her own mind. When betrayal strikes from within and enemies attack from without, Willow must make an impossible choice: save herself, or save the wolf who has become her entire world. In a final, devastating confrontation, Kael faces the Feral Shift in front of the entire Pack. Only Willow's unprecedented psychic command - and her willingness to sacrifice everything - can pull him back from the brink. Together, they forge a revolutionary new law: the Alpha's power is incomplete without the Mate's wisdom.

My physics teacher held up my test paper with an 18-point score in front of all the students and parents and said, “Students like this are hopeless. I don’t even know how someone like this passed the high school entrance exam. “I didn’t think there was a way to cheat on the high school entrance exam, but it turns out there is. It gives people like this a chance to cheat.” He did not just insult my intelligence but also questioned my character and family. “Well, it’s not surprising. Only a junk-collecting family could raise a kid like this.” I curled up in my seat, too scared to say anything. But my stepmom could not stand it anymore. She smacked the chalk box off his desk, pointed at him, and yelled, “Who do you think you’re talking about?! “I send my kid to school and pay all the tuition and book fees! How did it turn into us being a junk-collecting family?! “You can’t even teach properly, and I haven’t called you out for it! Have you no shame?! You don’t deserve to be called a teacher! You’re just a piece of trash!” For some reason, she suddenly seemed imposing and heroic to me.

On the way to get our marriage certificate for the twentieth time, Rolf Trivett regretted it once again. In eight years, this was our twentieth attempt to get the certificate. But every time we reached City Hall, he would always say he needed time to care for his seriously ill childhood friend and couldn't promise to marry me. This time, I couldn't take it anymore and asked him, "If she’s never going to get better, does that mean you’ll never marry me? What am I to you?" Rolf immediately lost his temper and yelled at me, "I've already promised to take care of her for life. Can you stop being so selfish? "Besides, we've been together for eight years. What difference does it make if we don't get this certificate?"

“I hate you. I’ve always hated you.” He gruffed in annoyance and I snorted while folding my arms. “Best believe the feeling is fucking mutual.” “Care to explain why you’re always giving me the ‘look’ then?” He demanded, a smirk tugging at the sides of his lips. “What stupid look?” “Like you want me to fuck you.” ~~~ It was a hate-at-first-sight thing. Ava and Mason got off an extremely wrong foot and hoped to never cross parts again.

Especially now that they had to live in the same house. Things drastically take a left turn when their parents plans a ‘first family’s vacation’, but were unable to make an appearance as scheduled because of some last minute changes, leaving Ava and Mason by themselves, all alone on an island. For three weeks. Ava passionately hated Mason, until she didn't. Till she couldn’t pretend to not notice how insanely good looking he was… till she couldn’t pretend to be immune to Mason’s intense gaze and lingering touches… Till she couldn’t deny that she wanted Mason to play her curvy body like she was his favorite guitar… Till she couldn’t deny that she had gone ahead and fallen head over heels, for Mason.
