Free Daysider (Nightsiders) by Susan Krinard

Alexia was no human serf, or a Bloodmistress who deigned to let him taste the nectar that flowed through her veins.
    Alexia was his peer. His equal, as much as anyone from the Enclave could be, though they were enemies and kept themselves alive by different means. He’d said he would never take her blood, and he had meant it.
    But now it was as if he were falling under the influence of an addiction, one that had once ruled his life and been forgotten until this moment.
    And Alexia was the drug.
    He stared down into her half-open eyes. He saw hunger in them—physical lust and the craving for pleasure, almost as if she, too, were experiencing the euphoric effects of some unknown narcotic agent.
    She wasn’t herself. He knew it, and he was ashamed of his own forbidden thoughts, his own struggle to maintain discipline and self-control that should have been second nature to him...and had been, until now. But Alexia held him there, demanding, refusing to let him go, and he forgot she was ill—forgot he could feel nothing for her—forgot his mission.
    He worked her mouth open with his and slipped his tongue inside. She sucked him in eagerly, grinding her hips into his pelvis, stabbing her fingers into his hair. Her small incisors grazed the inside of his lower lip, and he felt a brief stab of pain.
    She’d bitten him. He jerked back, probing the tiny wound with his tongue. He knew that dhampires were forbidden to take blood of any kind. That they were taught to loathe the very taste of it, even though it could sustain them as well as it could any Opir or Darketan.
    Yet she had bitten him. Had she forgotten who and what she was? Was she reverting, becoming something a lifetime among humans had suppressed?
    She pulled him down again, putting a quick and decisive end to Damon’s speculation. This time she used her own tongue to tease his into her mouth. He felt the sensation of it all the way down into his belly, and his cock swelled until the ache exceeded anything he’d suffered in the hollow when he was fighting to survive.
    Alexia couldn’t have missed the pressure of his groin in the cradle of her thighs, but she didn’t stop. She lifted her legs and wrapped them around his waist, rocking and thrusting as if they were both naked and she was begging him to enter her.
    Damon groaned. This couldn’t be happening. Nothing about this was sane, or right. But the more desperate his need, the less rational he became.
    It was instinct, pure and simple. This couldn’t end until he was inside her, thrusting deep, hearing her gasps and moans of pleasure. And surrender.
    As if her own thoughts had merged with his, Alexia began to tear at his shirt. She managed to unbutton it without ripping it to shreds and clawed at his undershirt, seeking flesh. Her fingers brushed his chest, scraping him with her nails as if she wanted his heart, as well.
    Damon took more care with her shirt, some remnant of sense guiding his hands, but Alexia wouldn’t allow it. She tore it open herself and ripped her close-fitting tank from neckline to hem, baring her breasts.
    They were perfect, like the rest of her, but Damon was too hungry to admire them for long. He bent to take one nipple into his mouth. Alexia arched upward, letting her head fall back, gasping as he suckled her, hard and fast, with no attempt at gentleness. His teeth grazed her tender flesh, accidentally drawing her blood as she had drawn his.
    It was sweet. Incredibly sweet, like the taste of her mouth or the way he imagined the rest of her would be.
    But he had not forgotten his vow never to take her blood. A vow that seemed increasingly impossible to keep. For it was as if, somehow, a part of his blood already flowed through her veins.
    No, not his blood. He had never taken dhampir blood before, and it was to be expected that its signature would be utterly different from anything with which he was familiar. But this was much more subtle than the unique amalgamation of strains that
