The first time Derek and I had sex? Well, it was more fucking than making love. I was home alone and he showed up at the door. He didn't say anything when I answered the door, just pushed me against the nearest wall and kissed me. It was probably one of the best kisses of my life. We weren't dating, I didn't even know he was interested, but I knew I was. When he let go of me, his eyes looked a bit scared, and if you know Derek, he's usually very good at hiding his emotions. But then I grabbed him and kissed him and he grabbed me and shoved me against the wall and kissed me like there was no tomorrow. He picked up my legs and put them around his waist before carrying me up to my room. He dropped me on the bed, and I smiled my most smug smile. See, Derek knew I liked him, but he'd never given any signs that he liked me, so this being the first sign, I felt pretty damn irresistible. Yes, Derek fucked me, didn't say anything, didn't make any noise, and when he was done he left. Without so much as a reach around! I felt like I was on top of the world, I could do anything, have anything, I was invincible. I called Derek, but he didn't answer so I texted him. I said, "If you're gunna fuck me, you're gunna be my boyfriend." I didn't say anything to anyone else, didn't do anything that would give away what he'd done, but I knew, and he knew.

After that I was a lot more forward when teasing him. My passive flirts grew blatant and he would look at me with that warning thing he does, but no one else seemed to read anything into it.

That was all well and good, until we got a letter saying mom's identity had been stolen. My cop dad (the infamous Sheriff Stilinski) knew all about it, dead people are perfect targets, but it really hit me hard. All the memories, all the panic attacks, everything came slamming back into me. I had a panic attack while at Derek's house, someone said something, and I went to the bathroom and tried to calm down, and he came in after me. He found me, and held me, and his hand rubbed my back, and he just whispered "shh its gunna be ok."

That's when we started being more than just that one night stand. I started doing things like jumping on his back and telling him to carry me. And taking food off his plate. And I might have played with his hair once or twice. And he stopped looking at me with that look, and instead just looked like he always did. Only there was something underneath, I mean, maybe I just imagined it, but there was something deeper. Something sappy, and cheesy, and so, so much in love with me. I mean, who wouldn't love me?

And he'd do things like punch the guy who stole mom's identity in the face, and growl at people who annoyed me. So I asked him if we were dating yet, and he said yeah.

You should have seen me. "Yeah" was the new best word in the English language. I was walking around, floating on little heart shaped clouds. It was so obvious. And Derek smiled, and pulled me in, and kissed me. And it wasn't the, i-need-to-fuck-you-right-now kiss, it was the i-am-so,-so-much-in-love-with-you kiss. It was probably one of the best kisses of my life.

So then we started actually dating, becoming official, finding time to go on dates what with the constant barrage of attacks on Beacon Hills, telling everyone, and, yes, lots of sex.

So yeah, Derek Hale and I had sex.

"Do you really think that's the best story to be telling a two year old?" Derek asked from the other room.

"What? It's not like he'll remember any of it." I retorted just as our son gurgled out a noise that sounded uncannily like "sex!" Derek looked at me with his i-told-you-so face. I grinned sheepishly and passed the child to him. "Fine you tell him a story."
