A/N: Yay! I'm back from vacation! And what a wonderful break it's been. Again, thank you for the comments, I love reading them! Enjoy the chapter (I know it's a little short, but I'll be updating soon) and be warned that there's a little bit of a more mature theme coming in.

We walk back to the train hand-in-hand, the wind from off the marsh whipping our faces and turning our cheeks bright pink. I'm quiet as I walk, still mulling over everything CJ revealed to me today. I see her casting me sideways looks, concern evident on her wrinkled brow but I make no effort to relieve her of her worry.

When we arrive at the station, I help her over the gate and stand with my back against the wood panels while we wait for the train. I close my eyes and take a deep breath before looking down at CJ who is, once again, eyeing me with slight apprehension.

"You alright?" she asks quietly.

I shrug. There's so much racing through my exhausted mind that I'm having trouble concentrating on any one thing.

"Did I do something wrong?" she continues.

"No, of course not," I answer, distracted. How can I admit my suspicions of her own suspicions of me without making her… suspicious? I'm so confused.

She wrinkles her nose in disbelief but instead of continuing her questioning, she once again reaches up and kisses me gently on the lips. I've never been really good with the "gentleness" of a relationship, but even I have to admit, this is kind of nice.

When she runs her hands up my chest and around my shoulders to connect behind my head, my misgivings start to fade.

After she pulls the back of my head down to deepen the kiss, my mistrust is almost gone.

By the time she softly moans, "Oh Eric," in my ear, I've forgotten what I was worried about in the first place.

My hands are resting in the small of her back, pulling her slight frame into my much larger one when I hear the rumble of the oncoming train. I reluctantly detach from the breathless CJ and grin when I see her devilish smile. She bounces on the balls of her feet next to me while we wait, both of us anxious to continue and irritated at the interruption.

I jump on first, and CJ follows very close behind, taking only a second to regain her balance before her eyes catch mine, and she literally SLAMS me into the wall of the moving train. I land with a grunt that is immediately swallowed up by CJ's lips on my own. Her hands twist through my hair, the sometimes-not-so-gentle tugging driving me absolutely wild.

Eventually I catch my opportunity to switch around so I have CJ pinned up against the wall, my hips pushing into hers to keep her steady, my hands on either side of her head. This seems to becoming a bit of a reoccurring stance for us. I smile lasciviously down at her and whisper huskily in her ear, "In a fight for control, I'll always win, Little Bull."

She grins innocently back at me but responds, "Don't be so sure about that," before crashing her lips into mine again.

I'm a little surprised when I feel her hands on my chest, slowly unbuttoning my shirt without disrupting our now slightly more feverish kiss. She pushes the fabric away from my shoulders and runs her hands under my black wife beater. I can't help it, I actually shiver. I feel her teeth against mine as she smiles into my mouth. With a growl I sweep her legs from under her but lower her slowly to the ground.

Her giggle catches me off guard.

"What?" I ask, breathing heavily.

She rolls her eyes at me. "Even in the 'throes of passion,'" she says with a purposeful dramatic flair, "you still remember your training."

I can't help but smile back at her. "But it was kinda hot though, wasn't it?"

She bites her lip seductively and nods. "Very."

I lay my weight carefully on her and break our makeout only long enough for her to pull my shirt over my head. I love feeling her hands run over my taught muscles, and in that moment, I'm very glad I've spent so much time training over these past few years.

I'm kissing down her neck a few moments later when suddenly I feel my world spin around. For a split second, I think the train has fallen off the track, but when I look up, a wide-grinned CJ is staring down at me.

"Holy shit, did you just sweep me?" I ask her incredulously. She only raises a challenging eyebrow from above her Cheshire-grin lips. "Jesus that's hot," I mumble, running my hands up and down her sides.

She laughs lightly before crossing her arms and lifting her shirt over her head. She tosses it to the side carelessly. I'm in awe of her beautiful body. Her eyes close as I run my hands up her bare stomach and sides; I'm amazed at how small she appears under my massive hands.

I reach around to her back to the clasp of her bra and wait until she opens her eyes before I continue. She gives an almost imperceptible nod before I too am tossing aside pieces of her clothing. When she leans down and presses her bare skin against mine, I'm momentarily so stunned with the way my night as turned out, that I don't notice her lips trailing down my neck until there's a sharp sting on my nipple.

"JESUS CJ!" I shout. "Did you just bite my nipple?" She laughs at my astounded outburst and runs her hands soothingly up and down my chest.

"I'm not as delicate as you seem to think I am, Eric. This isn't exactly my first time," she says with a smirk.

Oh shit, she thinks we're about to have sex. "Wait," I say, cautiously. "Are you sure you want to do this Ceej?"

"Eric," she says again. "I'm not some little sheltered princess you need to take care of! Stop trying to protect me and fuck me already dammit." Her face is so serious and frustrated I have to fight not to laugh.

Instead of answering, I sit up so she's sitting in my lap, her legs wrapped around my back and kiss her deeply.

I wait until I feel her lean back after unbuttoning and unzipping my jeans to bend a leg behind me, grab her around the back, and once again, flip her so she's trapped on the bottom.

"That's not fair, you're bigger than me," she says petulantly.

I'm reminded of the first time she said that to me, and I want to say something snarky back, but instead I shrug and say, "If we're doing this, YOU don't get to be on top."

She pretends to pout for a second while I kick my pants off but I think she's accepted her inevitable positioning because she too is wriggling out of her training pants. Oh fuck, she's not wearing underwear.

This girl, is going to kill me.

I'm not sure I can call what we just did "making love."

It was rough, and a little frantic. Jagged fingernails leaving red streaks down sweaty backs. Hair whipping uncontrollably, laughably, from the wind rushing through wide open doors. Bumps in the tracks leaving us giggling, and a little bruised, from our occasional tumbling. Let me tell you, having sex in a moving train is NOT easy.

But I feel like calling it "fucking" takes away from the sensual parts of it. The hitched breaths, quiet moans, eyes closed in a lasting, gentle kiss…

So I'm just not going to call it anything, and refer to it as "the incident" in my head. Let CJ figure out the proper wording. That girl does have a way with words.

"Good fucking job," she compliments as I roll off her and lay, still panting, at her side. "That was fucking awesome."

I raise an eyebrow at her, but she continues to look at the ceiling of the train, a small clump of hair plastered against her sweaty forehead. Like I said, she's got a way with words.

I sigh and clasp my hands behind my head while I try to catch my breath, but I catch a glimpse out the door and realize that the compound is coming up fast.

"Shit CJ," I call, sitting up and grabbing for clothes.

"What?" she asks, alarmed.

"We've got like 30 seconds before we gotta jump."

"Well fuck," she groans, reaching around the dark cavern for shoes, a sock there, and fuck, fuck, fuck, where is my shirt?

We end up jumping half dressed, me cutting my feet up as I land with only one shoe, and CJ wearing my shirt since hers got ripped out the door somewhere down the tracks.

We creep along back hallways and hide our snickers as we sneak through Dauntless. I walk CJ to the initiate dorm and pause, my hands clasping hers. She reaches up and kisses me, just one, quick, chaste kiss before she winks, and slips in the door. And that's how our night ends.

I stare after her for a moment and hear a sleepy-voiced girl ask, "CJ? Where have you been? Whose shirt are you wearing?"

I smile when I hear her respond, "Shut up and go back to sleep, Christina."
