Mark pov

After about three hours, we finally made it down the mountain. It wouldn't have taken so long if we didn't have to stop every two seconds so Jack could study every single thing. He looked at them with the same motionless face but his eyes somehow looked different. A sense of wonder and curiosity was in them, more colour also seemed to be there too. Seeing that made me smile, he looked beautiful.
I jumped off the last small ridge and landed on the ground like a badass.
I look up to see Jack still on the ledge, looking down to me.
"C'mon Jack, don't be afraid," I shout up to him. He starts shuffling away from it and looking away from me, was he scared?
"Hey, if it makes you feel better I can catch you if you want," I say holding my arms in the air. He looks back at me, a bit hesitant.
"C'mon, you can trust me, I won't let you get hurt I promise," he looks down at the not so far drop then back at me.
He closes his eyes and starts falling down.
I catch him by his waist and pull him close to me.
"See, your safe," he looks up at me and our eyes lock.
I swear I could get lost in those glorious blue eyes of his. I hate it but I can't deny it... I love him so much.
"Do you want to do it again?" he asks, I give a look of confusion.
"Do you want to kiss again I mean?" he says and I blush looking down. I really did.
He took my chin just like I did the night before and kissed me. The second our lips touched I got addicted to the taste. We kissed for sometime before I started poking my tongue at his lips. He didn't do anything, I remembered that he didn't know how to kiss. I gently took some of his hair and tugged it, making his lips open slightly. I slipped my tongue in and explored everywhere. We parted for air, a strand of saliva still connecting us. We were panting, trying to catch our breath.
"That... Is called... A French kiss... People do it... to deepen... A kiss," I say between pants. He nods in understanding. I realise I was still holding him tight to my body and also off the ground. I let him go so he could stand on his own and we started our journey to wherever we could find civilisation. I glanced at him at one point and his cheeks were slightly red, oh no, is he getting sick? I stop and put my hand on his forehead, checking for a fever.
"Your face is red, are you ok, are you feeling sick?" I ask worried.
"N-no, I'm fine," did he just stutter? No, must have been my imagination.
We start walking again.
After some time I felt something cold slip into my hand, looked down to see another hand in mine.
It was Jack's, I look up at him to see his face even redder and he was looking at the ground.
I smile and look forward again, squeezing his hand slightly.
This is good progress. I really think he's starting to feel emotion.
I'm happy.

Jack pov

I've been feeling these strange feelings ever since we left the cave. Everything I saw made me distracted from what we were supposed to do.
I observed everything, studying the shape, size, colour, it just looked so interesting.
Mark didn't seem to mind, in fact, he started smiling every time I looked at something.
We got to a ledge and Mark jumped of and landed on the bottom with ease.
I looked down at the bottom and I felt something in my stomach that made me not want to jump.
He started encourageing me and telling me to trust him and that he won't let me get hurt. Hearing that from him made the feeling subside a little. I stepped closer to the edge looking down at him and his outstretched arms. Something in my chest fluttered as I braced myself and started falling. For about a second I was in the air, then I felt strong arms wrap around my waist and pull me close, I held on tightly as if my life depended on it. I felt safer in his arms.
I looked up at him and stared into his chocolate eyes, he was looking at me the same way he was last night before we kissed. I asked if he wanted to do it again and his face was almost as red as his hair. I held his chin, mimicking his actions and kissed him. He instantly kissed back. His tongue poked my lips, then he gently tugged my hair and slid his tongue in my mouth. The strange feeling in my chest flourished around my whole body and made me feel a bit hot. We were both panting when we separated.
He let me go and we started walking, my face was slightly red and the feeling in my stomach intensified when he touched my forehead. He thought I was sick but I reassured him I wasn't. After a while, I put my hand in his, I don't know why I did it but he seemed to accept it and also give a small squeeze.
We walked for most of the day, still holding hands and searching for any signs of civilisation.
As nightfall hit we decided to take a rest for the night near a small river and search more tomorrow.
He made a fire while I sat next to him, watching him at work, with small beads of sweat on his body as he mended to the tiny flame he made.
I gulped, feeling yet again a different feeling, but this time it was further down my body.
When he was done he sat next to me, looking satisfied at his work.
Suddenly, my stomach started growling and so did his. I think he said it was called being hungry.
He started chuckling, "first thing tomorrow we'll get some food, I promise. For now, try get some sleep," he smiled at me before laying down close to the fire. I lay down as well and try falling asleep. The temperature drops and I start shivering.
I suddenly feel warm arms wrap around me, making me feel warm again. I look up to see him smiling down at me and for the first time in a century, I smiled back.
"I love your smile," he said while stroking my hair. He hesitated for a moment then kissed me again. He did it the same way we did earlier today and that feeling in the lower regions of body came up again. We parted as we caught our breath. I snuggled up to his chest and he held me close. I breathed in his scent, finding comfort in it. His heart beat and smooth breathing soon lulled me to sleep. But before I did I heard him say something that I didn't quite catch before falling into a dreamless sleep.
