Dangerous little secret (NALU fanfic) (lemon!!!)

Cht 7.

I, Lucy Heartfilia pledge to be the most irresistible, untouchable, mage ever.
Well... I can try...
(Time skip, Lucy is at school with Lisanna and her cameras ready for action.)
"Lucyyyy this is boring... this could all just be a prank." Lisanna groaned as she laid her head down on the teachers desk. "A prank that someone has took way to far!" I exclaimed, and sat up crossing my arms. "If you say so." Lisanna sighed, "you'll see, when I catch them I'll make them admit what they've done and I'll put them in jail for what they've done-" "what are you guys doing?" A familiar voice said behind me, frightening me, I jumped forward and turned only to see the one and only Natsu. Ugh, he's so handsome! I quickly straighten myself out, trying to play it off. He looked confused and curious. "Uh, n-nothing. Just uh, here." I said, and might I add that came out better than I thought. He chuckled and I swear I could feel my heart almost burst. He went and sat down at his desk, "Lisanna do you have any plans this weekend?" He asked, and just like that my heart felt as if it was now breaking into a million catastrophic pieces. Lisanna rolled her eyes, "fuck you draganeel." She didn't mean it. She used to like him, that's how bixlow and Lisanna almost broke up. But she acted as if she could kill him just for me and bixlow. She wanted us to be happy. I stood in silence, looking down at the ground as Natsu shrugged. I thought about leaving but then I knew I couldn't leave Lisanna alone with him. If Bixlow came and saw them alone he'd get the wrong idea. "Lisanna." Natsu said as he got up and walked over to her. He placed his hand on the desk where she now raised her head from. His face inches away from hers. I almost wanted to grab him by his perfect hair and push him away, but I froze. That's when Bixlow walked in, his eyes looking at Lisanna and Natsu. He scoffed and walked off, all you could hear was the chair fall down and Lisanna running after Bixlow.
Now it was just me and Natsu. Alone. Awkwardly standing here. Ugh! I have to say something, that was so rude!
"Why can't you just leave her alone?" I mumbled, my eyes looking at the ground once again.
"Why should I?"
"That's a stupid answer."
"That's a stupid question."
We stayed quiet for a couple seconds before I grabbed my bag, "whatever." I said, before I walked out. I can't believe I actually like him! I wanted to punch his perfect face in!
"Lucy wait!" I turned back to see Natsu running after me. He caught up since I was only a couple steps ahead. He ran his hand thru his hair and smiled at me. "I didn't mean it like that. I've just had a really bad day. I didn't mean to take it out on you or Lisanna. Scouts honor." He raised his hand and chuckled. God was his chuckle the most amazing thing. I couldn't help it,I was still mad at him but at the same time I just wanted to love him! I don't know what came over me. Before I knew it, I cupped his face and kissed him.  It was the best kiss that I've ever had, but I don't know why when I did kiss him all I could think about was when I was kissed by the mysterious person. I pushed Natsu back in result. I wiped my mouth away, 'I wasn't into that.' I kept repeating to myself. Sadly, my mind just kept taking me back to those memories. I kept finding myself back in a place where I couldn't see, where I couldn't figure out where I was. Back to the kiss that felt as it were my first, back to here. When I finally opened my eyes, I felt the tears down my face, my hand felt sort of numb, and I could see Natsu. His face seemed concerned and hurt, then, I noticed the hand mark on his left cheek, where I unconsciously slapped him. In the corner of my eye I could see students, classmates, and even a teacher.
'What did I just do?'
