Disclaimer- Pendergast belongs to Douglas Preston and Lincoln Child. However, Halo Spencer belongs to me and he will eventually be in my Harry Potter fic "The Prince of Flame", which I'm still sort of working on… Enjoy!

Chapter 4

Halo had never thought that at age nineteen, in his third month with the FBI, he'd be having sex with another agent. Sure, it had been a fantasy to find an alpha male to play with, but he'd never actually expected to find one. He didn't know if Pendergast was gay or even bi. He'd felt the absence of a wedding band when they had shook hands at the beginning of the day, but the agent could have just taken it off for the case.

Halo decided to ignore the strange situation, how odd it was that one of his little fantasies was actually happening, and went about the process of marking Pendergast's neck with his teeth. The blonde turned his head to the side on the pillow as Halo licked along the muscle of his neck, sucking at the sensitive skin before setting his teeth to it. He slipped his hand into Pendergast's hair and pulled his head back more so that he could actually bite the man. He felt blood rush to the surface and he pulled away just a little.

"That's probably going to leave a bruise," He told the other man.

Pendergast shrugged. "That's sort of the whole point, isn't it?"

"Yeah," Halo murmured and lowered his mouth back to the once perfect white skin.

Pendergast's hands roamed up and down his bare back, caressing along his spine and then gently adding pressure to his lower back. Almost like he was trying to bring their bodies more into contact as Halo was lying to his side and not completely touching him.

Halo shifted his hands, the one that had just been resting on the pillow traded with the one in Pendergast's hair and the one in his hair started to slowly stroke down his chest. Halo's hand stroked once over his nipple before the fingers pinched it, the older man's breath hitched then became steady again. The hand left the nipple alone and moved downward, coming to a stop at his navel.

….

Halo put his mouth on my neck suddenly, his tongue making the skin slick before he sucked on it. I turned my head to give him a little more room, but it still wasn't enough for whatever it was he had in mind. His arm crossed over my chest and one of his hands was suddenly in my hair, pulling back on my head, exposing more of my throat to him and I felt his teeth brush my skin before he bit down. I fought down a moan as his teeth began to hurt me; he pulled away just a little bit but I still felt his breath on my now very sensitive skin.

"That's probably going to leave a bruise." He told me and his breath tickled me.

I shrugged like I didn't care, and I didn't, not about the bruise anyway. "That's sort of the whole point, isn't it?"

"Yeah," Halo whispered and went back to biting my neck.

It actually hurt a little and I lifted my hands to his back to distract myself from the mild pain. I caressed his skin from shoulders to lower back and shoulders again; I put pressure on his slim waist when he bit a little too hard. He shifted his hands on me, the left that had been above me on the pillow, took its own place in my hair. His right hand made a slow pace down my chest until it came to my nipple. He pinched me, pulling at the skin with his fingers like he was doing with his teeth, and my breath caught in my throat. He stopped suddenly and his hand left my nipple, sliding down the center of my chest and stopping just over my bellybutton.

He continued to work my skin between his teeth while the hand on my stomach moved back and forth along my waistband. He was nonverbally asking permission to touch the rest of my body. I slid my hand down his arm until I came to his wrist and I placed his hand on the tie-string of my pants. He bit into my neck viciously and I arched with the pain of it; I felt his tongue lap up the blood as I squeezed down on his hand.

"Sorry," He muttered against my torn flesh.

I lifted up, grapping his thick hair and throwing him to the bed beneath me. He looked up at me, terrified as I inspected the wound on my throat. It wasn't deep, but he had managed to open my throat with his teeth and the blood, though a small amount was flowing freely.

"I'm sorry," He said again.

"It's okay." I touched his cheek lightly. "Little vampire…let me return the favor."

I started with his neck, and repeated exactly what he'd done to me. Using his hair to pull his head back at an angle, licking and sucking before I bit him. But I only held my teeth to his neck briefly before suddenly sliding down his chest and taking his pierced nipple into my mouth and between my teeth. He gasped and grabbed at my shoulders, trying to push me away. I pulled on the ring with my teeth at the same time flicking my tongue against him. When I got the briefest taste of copper, I pulled away completely and just leaned over him looking down into his eyes.

Halo's hand came up and touched his bleeding nipple carefully; probably afraid I'd torn the ring out. He slipped his arm around my shoulders and pulled me down, kissing me.

"Demon," He whispered when I pulled away again.

"Takes one to know one," I said, using the phrase I'd heard Charles say a hundred times.

He reached up and touched my cheek, feeling the light stubble on my chin. It was a caress close lovers would share, not two people about to engage in a one night stand. In that moment, I didn't know where my actions were taking me. Halo's hand slid down my throat and chest stopping once again at the waistband on my pants. Asking without asking. I gave permission without speaking.
