Title: Folie à Trois

Timeline: pre-season 4 (late season 2 or season 3)

Summary: Was I seriously going to try and seduce both my ridiculously attractive co-workers at the same time?

CHAPTER 3

I turned fully and pinned her with my eyes. It worked like a charm; she straightened on the spot. She backed into the sink and curled her elegant fingers around it.

I picked up another ice cube and advanced until I crowded her space just as much as Booth had been doing when I walked in – with equal results.

She tilted her chin and looked at me defiantly, daring me; challenging me. Didn't she know by now that she'd met her match in me? Play with fire and you might get burned.

She didn't look away even as I leaned in close and lightly touched the ice cube to her lips, but I only let her have a teasing taste. My hand guided the ice cube across her forehead, temples, heated cheeks, and her jaw. Slowly. I watched her lips part and her eyes slip shut. How she seemed to strain towards my relieving touch.

While my fingers were spreading the sweat dewing on her skin across her delicate collarbones, my other hand let the cube travel down the long, smooth column of her throat. A trickle of ice water raced down her neck, mingling with perspiration along the way, and disappeared into the low neckline of her tank top. I chased it with my eyes and realized I was only atoms away from chasing it between those glorious breasts with my lips and tongue.

Taking a deep breath, I tried to refocus on my task. That wasn't made any easier by the fact that when I slowly blew out that breath, against her neck, she tossed her head back and uttered a hum of pleasure low in her throat, shivering.

"Hmm, that feels good. Don't stop."

My sex throbbed in response to her throaty whisper. I had always suspected that for all her clinical detachment and matter-of-factness, she harbored a sensual power within. But to witness that sensuality unfold like flower petals, up close, was a raw, heady and exciting thing. Much more than I had anticipated. Maybe I was the one playing with fire here, not the other way around.

I could feel Seeley's eyes burning a hole into my back. I could hear his ragged breathing. Oh yes, he was turned on by this.

I wasn't quite prepared for how it affected me either – or Brennan. This was supposed to be just a little mischief, to rattle her and – frankly – especially Seeley. But now I was confronted with the reality of looking at Brennan's dilated pupils, the flush on her cheeks that was not just from the heat, her soft eyes, and I imagined I was sporting a similar look at the moment.

And I couldn't walk away. Not yet anyway.

Was I seriously going to try and seduce both my ridiculously attractive co-workers at the same time?

"Do you want this, Doctor Brennan?" I taunted, holding up the ice cube.

Her lips parted again and she nodded slowly as she stared at the ice cube, mesmerized. Her pink tongue darted out to moisten her lower lip.

"Then come and get it," I smirked.

With that, I bit down on the ice cube to hold it between my teeth, and tilted it up in silent but unmistakable invitation.

Brennan was game. For as long as I live, I will never forget the self-satisfied, cat-that-ate-the-canary grin she sported as she pushed off the counter once more. She held it as she closed the space between us, tilting her head, drawing ever nearer, with agonizing slowness, until she could close her lips around the coveted frozen goody I held.

She took her time feasting on it, and luxuriously worked her tongue and lips around it, leaving no doubt that she was aware of what that ice cube was a thinly veiled excuse for. Those pretty lips were actually barely brushing my fuller ones, but were nonetheless setting me on fire, making me shiver in the warm air.

"That's enough, Cam."

Booth's voice was rough and tight as he barked his command at me.

Oh? Getting territorial?

Brennan pulled back, her teeth stealing the ice cube while I was distracted, and looked over my shoulder at Booth for a moment.

Booth had addressed me, but clearly, his attempt to stop this was in fact aimed at his partner. We must have really hit a nerve, or we would never have managed to provoke him like that.

I considered that from his position, he couldn't see that the ice cube had been a constant barrier between our mouths; for all he knew, we could have been tonguing with gusto. Too bad we weren't. I could see how that thought would upset him though, him being head over ass in love with her and all – if he was trying to hide it, he was doing a piss-poor job of it.

Brennan took the ice cube out from between her teeth to look at Booth and tease, "Maybe he just feels left out."

With a wicked grin, she sought my eyes again, and the glint of lust and mirth in her eyes took my breath away. What had I unleashed here?

When I half-turned to look over my shoulder at Booth, leaning against the opposite counter, strangling it, she pushed past me – close enough that her hardened nipples brushed mine in passing, and sent a jolt through me. My breasts had grown heavy and sensitive from desire in the brief moments I had spent touching her.

It was a novelty for me, seeing our constant friction and awareness of each other in a different light tonight. Because I had to honestly wonder if it was really any different from her bickering with Booth? And there was no doubt in anyone's mind what lay underneath it when it came to the two of them.

I turned fully to see impossibly long legs and bare feet padding over to Booth with that same enticing sway in her hips, making those perfectly shaped buttocks wiggle attractively in her form-fitting shorts.

Booth was starting to squirm and getting that tight, terrified look about him. If she was looking at him the way she had just been looking at me, I could imagine.

It was that look, which confirmed my suspicions that their sexual tension was still unresolved, although I wasn't so sure anymore that wouldn't change before the night was over – an unexpectedly thrilling thought.

"How rude of us not share our refreshing treat with you," she husked.

Dear lord, that smoky timbre would have been enough to give any man a tight crotch, no matter what she said with it, but the hint of flirtation in her voice would certainly do him in.

Sure enough, over Brennan's shoulder I saw his jaw fall from its previously secure position and drop slightly. His eyes melted into hers. He opened his mouth to protest, but before he could, she had popped the ice cube in her mouth and pressed it against his.

I was over Seeley. I really was. The spark of jealousy I felt at seeing him so ardently kissing another woman was brief and lackluster. I felt a different kind of spark at the sight before me: large, talented hands wandering across her slender back.

They were standing here doing this in front of me as if I weren't even here. Not including me. When I was the one who started this. That was just rude. Unacceptable.

Too overheated to consider the wisdom of my actions, I marched over. At the sight of Seeley's gorgeous lips so passionately entangled with hers, however, the rebuke died in my mouth.

It was…intriguing, to see him like this. I knew what it felt like to be at the receiving end of his kisses, but I'd never seen him kiss a woman, not like that anyway, as a spectator. The sight of it rooted me to the spot.

Wow. They were really getting into this. The ice cube must have melted long moments ago, having a snowball's chance in hell in the heat of their attraction to one another, but they were still kissing. Hotly. I saw flashes of tongues dueling in their tangled mouths. She gripped his hands where they held the counter and pressed herself against him unabashedly, her heavy breasts flattening against his chest.

I dry-swallowed a few times and tried again, first clearing my throat. "Excuse me. Don't you think it's rude to be having this party in front of me?" I crossed my arms in an attempt to strengthen my challenge.

They sprang apart guiltily, panting and flushed. Adorable. Appetizing.

Brennan took a step towards me, until she was right in front of me, toe to toe, and it was all I could do not to flinch.

In my peripheral vision, I saw Booth blanching visibly when she asked seriously, "Are you saying you'd like to be included?"

She had that intense look on her face and a tiny frown between her eyebrows. Still, I had a hard time deciding if this was a bad joke or a serious question, until it hit me: this is Brennan.

She shared a look with Booth. Not seeking his permission as much as checking if he was on board with whatever she was planning in that big, genius, resourceful, sexy brain of hers. Booth said nothing. Of course he didn't. Anything she wanted. Anything at all.

Which, frankly – once those blue-eyed puppies focused all their intensity on me – I completely understood. Anything she wanted. Anything at all.

Kiss her? You got it.

Note: Is it in hot in here? ;-)
