Sneak peek: "I don't believe in God, Hailey," he murmured, as his firm hands settled on my hips and lifted me from his lap, placing me onto his desk, "But... if I did, I would have thanked him for making you." A soft gasp escaped my lips as his hands slid under my college skirt, his fingers brushing on my pussy over my panties. "Damien, you are my brother..." I managed to whisper amid overwhelming desires. This felt so wrong. He emitted a husky chuckle, leaning closer to my ear, his lips brushing against my earlobe. "Correction-Stepbrother." "But-" Before I could utter a word, his hand swiftly slipped down inside my panties, his fingers landing on my bare, wet heat and just when a moan could escape my lips, his mouth forcefully met mine swallowing the scream of pain as well pleasure when two of his fingers thrust into my pussy just like I'd felt them in my dreams... *** When I was dragged across the country to Los Angeles to live with my mom's new husband and his son, the last thing I expected was for my stepbrother to be off-limits.

I was his dirty little secret, one that he wouldn't let go of, accept, shatter entirely, or mend. I was his toy; Well....his favorite one.

“Reject her.” Jake blinked at Ana stupidly. “What?” “Reject her now Jake! If you love me and want to keep me as your wife, reject her and break the bond!” Ana screeched as her hands balled into fists. “I’m sorry Ana, I can’t do that.

I was a stray pup. At five years old, several elite warriors captured me and threw me in front of the Alpha heir, Lucas. I heard his wolf talking to Lucas in his mind. "Lucas, this damn little thing is a hybrid of a werewolf and an evil witch. The prophecy shows she will be extremely vicious in the future, even killing your Mate. For the Moon Goddess, you must kill her now to protect your future Luna." Lucas agreed carelessly. But when he saw me, he froze. "Seriously? Dude, you’re saying this tiny thing is a homicidal maniac? How vicious can she be? Cursing the future Luna with a lollipop?" I tugged the corner of Lucas's expensive shirt, and looked up. "Big brother, I'm so hungry." He looked at my body, starved to just bones, and hesitated. "Anyway, the mate hasn't appeared yet. Might as well let her eat first. Even when we execute rogues, we usually let them eat their fill before killing them." His wolf replied, "Makes sense... but after she's full, you can't hesitate again!" From that day on, he raised me, this mixed-race brat, like a little sister in his pack. For over a decade, he and his wolf plotted countless times how to kill me, but always found various excuses to postpone the execution. Until I was 16, my brother was injured and lying in the healing center, but his wolf, having lost its will to live after being rejected by its mate, was unable to heal itself. The healer said my brother was going to die. I didn't try to stop him; I just found that playboy from school who had harassed me. I forced him to send my brother a mind link. "Alpha, I just wanted to say, Emma's body is really... really banging. I'll take good... care of her for you." I even chimed in through the mind link with a flirtatious whine. "Jason, don't be like that, Lucas will get mad... stop it." Less than half a second later. An earth-shattering roar came. "Son of a bitch! Jason, get the fuck away from her!" "If you touch a single finger on her, I'll tear you to shreds!"
