So today was the day myself and Caroline and I moved to Mystic Falls. Before here, myself and Caroline we were attending college in Chicago. We both attended Chicago Land University, just east of the downtown clubs. I studied to be a fitness trainer. I graduated 2 years before she did, but I stayed with her while I waited for her to graduate. We decided to move back to Mystic Falls to settle down, maybe have kids...

But now we've JUST moved back to Mystic Falls, and we've yet to finish unpacking. We moved into the boarding house of course, since I already owned it...the boarding house was a genuine 1900's style house. Old dark wood, with large windows to let in light during the day. Painted in a dark black color, and oak double doors. Truly something out of a movie.

As I wandered upstairs, I wondered what Stefan was up to, not that I cared much. After he broke my best friend Elenas' heart, I was fucking pissed. I guess in some way I should be thanking him, because I got with Elena after that, but I still hated the bastard for what he did to Elena. But we weren't even going to discuss the shit that horrible excuse for a human being did to Elena. I wondered what Elena was up to? I haven't seen her in almost six years before I was with Caroline. Our bedroom had a big window, which I could not understand since it just faced the house next door.

Sitting on my bed, I remembered that when I left for college I left my room as is. This means my sheets have been collecting dust for four years. I needed to change them badly. My mind started to wander to the last time I was actually in this bed…

"Elena, you look beautiful this morning", and really she did. She looked amazing; she wore this deep blue dress that hugged her curves in all the right places. I felt myself staring, not that I cared. She was beautiful and she knew it. She dressed this way just for me, and even wore the necklace I gave her. It had two hearts connected and the letters D&E engraved. On the front, not the back. I wanted people to know she was mine. Anyway, we walked into the house, I could immediately see the frown forming upon her face seeing all the boxes around. I'm guessing she realized it was real now…I really was leaving for college for four years. Four years without my beautiful girl by my side. Man, I was going to be a mess. I had made dinner, a great Swiss roast with carrots and potatoes. Something that could cook while I packed, but still delicious.

I don't think we ever made it to dinner however…as I shut the door behind her, she immediately wrapped her arms around my neck and her lips were on mine faster than you could say bippity bop pity boo. She tangled her hands in my hair, and wrapped her legs around my waist.

"Never let me go baby", she almost moaned at me while I sucked on her neck.

"Don't worry babe, I never will".

Now I kinda felt bad, I had let her go when I met Caroline.

As I was coming out of my memories, which I could go on forever about; I threw the sheets on the floor, and turned around as I saw movement out of the corner of my eye, A sudden movement caught my attention.. I looked out my large window, and holy shit there was Elena stood next door. Fuck me; if my dick wasn't already stiff as a rod from the earlier memories, there she was walking around her bedroom in only her lingerie. Holy hell, I knew I shouldn't be looking but I couldn't tear my eyes away. Time had been great to her, she definitely filled out in a few certain places THAT I could see…she bent over to get something out from under the bed and I almost lost my shit right there. I wanted to go over there and ravage her right on her bed. She looked so fucking hot, and ready for anything…god what was I thinking, I love Caroline.

I decided to go downstairs and wake up Caroline.

I nudged Caroline awake, "Wake up beautiful, I want to go get something to eat. Let's go to the Grill." I told her. I wanted to show my girlfriend the town…and get rid of this raging hard on, but there would be time for that later. Right now, I was starved.

She wasn't from here; she was from St. Louis, Missouri, and I wanted her to feel comfortable here. We got dressed and headed to the Grill. We walked in the door, and instantly I noticed who was behind the counter. Bonnie motherfucking Bennett.

"What the hell are you doing here, slut?" I sneered at her. I could see Caroline quickly becoming uncomfortable in this situation…shitttt….

"I work here Damon", She said clearly displeased I was here talking to her. "Still pissed off at me I see," she said all matter-of-factly.

"Damn right bitch, I am. You fucking slept with my brother and broke my best friend's heart. She was your best friend too, how could you do that to her? Oh yeah, because you're a cold hearted bitch!" I coldly whispered to her, just loud enough that no one else could hear. Except for Caroline, who was currently glued to my arm, apparently trying to pry me away from this shit.

"Come on baby, let's go someone else," I told Caroline. I was seriously pissed. As we turned to walk out I bumped into someone. I turned around to apologize; no I was going to yell at them, I came face to face with Elena. Guess it was now or never.

Elena was truly ecstatic, "Damon! Oh my god!"

"Elena!" I said, God I had missed her so fucking much. We hugged tight, and I said, "You look so different, you look great!"

Caroline cleared her throat.

"Sorry baby, this is my best friend Elena Gilbert. Elena, this is my girlfriend Caroline. We just moved back." I told her.

"Pleased to finally meet you Caroline," Elena smiled at Caroline.

"I've heard so much about you Elena and seen so many pictures as well. Damon's right, you are beautiful." Caroline told her.

Elena smiled sweetly, "Thank you, so where are you two living?" Elena asked. Oh damn, this was gonna be good.

"In the boarding house…" I started to say.

"Really! Oh my god! Guess where I'm living now?"

Elena asked me, obviously enthused. Gotta act surprised!

"Where?" I asked, trying to act clueless.

"Right next door to you!" Elena squealed, overjoyed.

Caroline piped up, "Oh my gosh! Really? We are gonna be the best of friends!", Caroline said. I guessed she was happy to know someone in this town. And she practically knew Elena already with how much I talked about her.

Caroline spoke up again, "Would you like to go to the carnival with us tonight, Elena?" Caroline asked Elena.

"Sure! That would be great", Elena told Caroline. Caroline knew nothing of mine and Elena's relationship previously, except that we were friends. Not that we were lovers, or girlfriend-boyfriend...just that we were friends, should I tell her? Naw, I'll leave it be. Let her have one friend, she's gonna need it.

I noticed Elena look me in the eyes, and then blushed and look away. I knew exactly what she was thinking.

We were at the county fair, walking around on a cool moonlit night, and we decided to find a dry spot and watch the stars. It was so romantic, exactly what I hoped our first kiss together would be. She sat up on her elbows, and looked at me through her big brown eyes and said.

"Damon, I know I'm not imaging things…there is something between us…" she told me, I will never forget the look of that love in her eyes.

"What, this grass?" I looked at her with my infamous smirk, "No, I'm just kidding…I know there is, but I didn't want to push you…" I leaned over and kissed her innocently. I rolled over on top of her, supporting my weight with my elbows. I stopped for a brief moment and said, "Elena, this is perfect. Just you and me under the stars, me kissing the woman I love…" then I leaned down and took her bottom lip in mine and sucked on it, and kissed her again. Rolling my tongue over her bottom lip asking for entrance, she opened her mouth and our tongues collided in bliss. We spent the rest of the night under the stars, content in each other's happiness…

God, that night was fucking amazing. It was the first night we were ever "together". It was damn good. I hoped that exact moment flashed before my eyes before I died.

Suddenly, I realized the memory I should want for that should be with Caroline…but those don't hold a candle to the moment with Elena. No they don't compare at all. Shit, and now we are going to the carnival together; I need to clear my head.. We said our goodbyes and agreed to meet at the carnival later.

Meanwhile Caroline and I went home. I planned on devouring her tonight before the carnival. I can't be losing my shit in public thanks to Elena. I decided, we could go take a shower and I could ravage her.

We walked in the door, and I grabbed her by the waist, and planted a passionate kiss on her.

"Come on baby, let's go take a shower and get ready for the carnival."

And with that, we went upstairs. We got in the shower, and as she went down on me, all I could think about was Elena. I needed to be careful, before I accidentally say her name or some shit like that. And even as we made love later on in the shower, all I could think about was Elena. What the fuck was wrong with me? I love Caroline, I shouldn't have thoughts like these, or compare the woman I love with my ex girlfriend, should I? Suddenly I couldn't wait for the carnival tonight. I needed to figure out my feelings for the both of them.
