Free Suck It Up by Emma Hillman

Someone who was in her room at night. Alone. With her.
    Pain slashed through him, as he stepped closer. His lion pushed to the forefront, roaring his displeasure when he breathed in the scent of an unmated female. He frowned. He knew that smell. He knew it. “That fucking woman!”
    He couldn’t believe Kellie would cheat on him so damn fast. They’d only been together for days, but she hadn’t been able to stop herself from sleeping with another woman? He knew he’d quieted her lioness, so she had no freaking excuse!
    Had she been lying all this time? Was everything a hoax? Maybe his dad had been right, and she’d cornered him into mating with her, landing one of the Alpha’s sons while she was at it.
    “I’ve been so fucking stupid,” he muttered under his breath.
    Anger already reddening his vision, he turned to leave then he thought he heard her call out his name. He froze and cocked his head to the side. Had he dreamed it?
    “I’m losing my mind now, too. Fuck!”
    Nathan. Nathan. Nathan.
    He whirled around, already moving closer to the window. Something was going on, and he intended to find out what. Now. Even if it meant walking in on them having sex. His lion hissed inside him, but he shut him up. His first priority was making sure his mate was fine.
    Sweat gliding down his back, he paused right outside the window and listened in. He couldn’t hear Kellie, but he could hear the other woman’s voice. It was too low for him to decipher what she was saying, but it didn’t stop him. Instead, it spurred him on. Rounding the house, he pushed open the back door and hurried through the house, only pausing when he stood right outside the bedroom.
    A voice rang out, clearer than he’d heard before, “I’m going to make you forget all about him. You’ll be so full of me you won’t remember his name, or yours for that matter. I brought a bag of toys with me, Mate. I’m sure you’ll end up loving them as much as I do.”
    Nails sprang forth from his fingers, digging into the soft flesh of his palms. He bit back a gasp of pain and slowly straightened his hands.
    The other woman wasn’t finished however. “Have you ever been taken by a woman wearing a strap, baby? You’re gonna love it. I’ll take you hard because I know you like that. I saw you with him last night, you know.”
    She what? He took a step forward, so furious at the thought of her spying on them he nearly flew into the room. Instead, he forced himself to remain still, waiting to hear Kellie’s response.
    Except nothing came. She remained silent, as if she wasn’t even there. Could it be? Hoping the door wouldn’t squeak, he tapped it a little. It opened wider, his eyes instantly focusing on the other side of the room. What he saw made his heart palpitate.
    His mate was lying on her stomach, tied to the bed with her clothes in disarray. She was partially naked, her top pushed up and her jeans tugged down her thighs. Her ass was red, redder than it usually was, and he understood why when he saw that woman apply some kind of contraption to it. It sizzled and left a faint mark in his mate’s soft skin.
    What the fuck is going on? He took another step forward, hoping his former patient would be too enthused by their weird play she wouldn’t notice him creep into the room.
    Was Kellie into BDSM? Why hadn’t she told him? If she got a kick out of it, he’d have dominated her like that, too. He’d have given her everything, but no, she’d thrown it all away at the first opportunity.
    Nathan…
    He jerked at the sound of his name. Neither woman had moved on the bed however. His lion pushed himself forward and focused on the lioness he’d claimed. Hurt , he told his human side. She’s hurt. Do something!
    He didn’t think. He sprung forward and slammed into the woman. She shrieked beneath him and immediately started batting at him with her hands. The tool she’d been holding fell on Kellie’s back, and this time, Kellie did call out. She
