Free No Mercy by Sherrilyn Kenyon

sank her hand in his soft hair, tugging at it as he continued to tease her.
                Dev growled at how good she tasted. It'd been way too long since he last had a woman. Hell, he'd had so little interest in them lately that he'd been begun to fear he was broken. But there were no inhibitions or hesitation with her even though he should have them in spades.
                He was sleeping with a Dark-Hunter. Who would have ever thought?
                Unable to stand it anymore, he pulled back from her. He lifted her hips to brace her against the black marble-topped table in her foyer before he drove himself deep inside her body. She cried out his name.
                Smiling, he thrust against her, seeking solace in her softness.
                Sam balled her fist in Dev's hair as she buried her face in his neck to inhale the warm masculine scent of his skin. There was so much power in him, so much skill in the way he filled her and touched her. It was like he knew every way to wring as much pleasure from every thrust as he could. And to be able to have him and not have his emotions overwhelm hers...it was incredible.
                For the first time in centuries, she felt human.
                "Harder, baby," she purred in his ear, wanting him to love her with everything he had. This was the most incredible moment of her life and when he finally came, she joined him.
                Completely spent and sated, she leaned back onto the table while he was still inside her. Her breathing ragged, she kept her legs wrapped around his waist while he stared into her eyes and toyed with her belly button. "That was incredible."
                He flashed a devilish grin. "Glad I could oblige." He ran his hand around her breast, traced the line of her bow-and-arrow mark, then gave it a light squeeze as he brushed her hardened nipple with his thumb.
                She picked his hand up and lifted it to her lips so that she could nip his fingertips.
                Dev shivered as her tongue darted between his fingers. He didn't know why, but it brought out a tenderness inside him. Something protective and scary.
                What the hell was that? It was like the animal in him wanted to claim her and kill anyone who came near her. Anyone who hurt her or even looked at her wrong. It was feral and powerful.
                Right now all of his paranormal powers were charged to their fullest. He felt like his entire body was made of thrumming electricity that needed to ignite and explode. Sex for Were-Hunters always heightened and strengthened their psychic abilities, but this was different.
                He'd never felt anything like it before.
                She nibbled his knuckle. "Is what I heard about Were-Hunters true?"
                "Yes, it's true. We all have a third eye hidden in our shoulder blade."
                She laughed out loud. "Where did that come from?"
                "The bowels of my imagination and my desire to hear your laughter. You have an amazing laugh and I have a feeling you don't do that much."
                Sam swallowed hard. He was right. She very seldom found anything amusing. Life was hard and she was hit with the reality of that fact every time she went near another person who was suffering. Which some days seemed to be everyone she came into contact with.
                But Dev was different. He saw beauty and humor even when he had to dig it out of crap.
                Or demon snot.
                That, too, made her smile. "I meant that you guys can go all night and have multiple orgasms."
                He pressed himself deeper inside her so that she could tell he was already hard again and ready for more. "Oh, yes ma'am. Definite perk for my species."
                She
