"Your son wasn't the only one late today," her mother hugged Clark.

There next to Clark was none other than my one night stand.

This has got to be some kind of joke, right? I looked around for a brief moment before turning to him. His eyes were on me as well. What was his name? What was his name? He had a superhero name. That's right. It was the Hulk's name. Banner, Bruce Banner, I deducted. Bruce!

His eyes were wide and I knew my face was pale.

"Didn't you always want a sibling, Lauren," her mother smiled.

It was then that his lips turned into a smile and he titled his head.

"I have a feeling that we've met before," he held his hand out to me. "Lauren is it," he smirked. "Funny, you don't look like a Lauren."

I stared at his hand for a while. "Well, you look like a Bruce," I stated as I gripped onto his hand and shook it once.

"It's a shame my name is Peter," he corrected. I shook my head annoyed that he told me a fake name. Then again, so did I. "It's a pleasure to meet you, sister."

We stared each other down, me with my eyes narrowed and the now known Peter with his smug smirk.

"Peter, you didn't need to dress for the rehearsal," Clark stated. He was still in his suit from last night. "At least take your tie off."

That's when I started to laugh. It was pretty loud and I had to look away because my mother was questionably looking at me.

"I wasn't sure how formal or casual this was," Peter stated while tightening his tie. I almost wanted to pull it off and show to his father the work that I had done. Oh my God what was wrong with me? This guy's father was marrying my mother!

"I just don't want you in the same suit all day," his father stated.

"I'll change later."

"Its okay, Lauren needs to put on her maid of honor dress still," my mother said. "And perhaps fix your hair, honey," she ran her hand over my hair.

"I'll try flat iron it at home," I assured her.

"I can give you a ride," Peter offered.

"No, it's okay. I drove myself," I smiled.

"Nonsense," my mother peeled away from Clark and took Peter's hand and took mine as well. "It will give you two a chance to bond. I really want the two of you to get close. After tonight," she smiled and shrugged her shoulders, "the two of you will be step siblings!"

"Oh God," I moaned.

Peter chuckled. "Not too loud there, Lauren."

I eyed him out before ripping my hand away from my mother and then walking towards some other relatives who had begun setting up. For some reason, Peter continued to find me and found all sorts of reasons to touch my hand, arm or shoulder.

"Come sister," he whispered in my ear while playing with the end of my hair. "They want us to practice walking down the aisle."

I spun around. "Stop calling me sister."

I tried to trip him as we were walking down which of course did not work in my favor. Peter moved and was able to trip me instead. He was being this obnoxious jerk and I couldn't help but think it was because of last night.

We had just finished rehearsal and I had to get back to change.

"Wait," Peter called out. "Remember I was going to give you a ride," he caught up to me.

"No I can drive there myself," I kept walking.

"Nonsense," he took my hand with that smirk of his. "It'll give us a chance to bond," he whispered in my ear.

"Lauren!"

"Mom," I replied turning away from Peter and looking at her.

"Peter is taking you home remember? I really want the two of you to get close," she smiled.

"We already were," Peter whispered again.

The horror!

Peter looked up at my mother putting on that sincere smile of his. "Don't worry about it Katherine," he called to her. "I'll get her home and back in time for the wedding."

"Such a sweet boy," she smiled and turned to walk away. Sweet boy my behind, I rolled my eyes.

My hand was taken quickly as Peter's car door was opened. I was surprised that I didn't even protest getting into his car. I still had time to run to my own but something about him taking me home for the second time in the past eighteen hours or so made my stomach turn. The second he got into the driver seat his hand reached around the base of my neck and pulled me towards him. Why did he have to be good kisser? He pulled away only to start kissing down my jaw and at that sweet spot on my neck causing me to moan.

"Not as loud as last night but I believe I can get you there," he said again continuing to kiss down my neck.

"You're so cocky," I titled my head further to the side.

He took the invitation and started to nuzzle his nose into me. "I know."

"And arrogant," I sucked in a breath as he bit softly at my skin.

"Mm," he hummed as I began to whimper.

His other hand had sneaked its way over and started to massage at my thigh. "And you're such a womanizer," I pushed him back remembering how he had stated that last night wasn't his first time. Peter sat back in his seat looking at me with a satisfied smirk. "Now hurry up and get me home so I can get ready for the wedding."

"Whatever you say, sis."

As I opened the door to my house, I couldn't believe that I was walking back in with my one night stand from last night. Don't forget that he's the son of the man whom your mother is marrying, Lauren, I shouted in my head. I walked up to my bedroom only to have him follow me. The second we were inside his arms wrapped around me and his lips were back on my neck again.

"You need some help getting ready?"

"No I just have to... oh," I moaned as our bodies were pulled together, his grip tightening and his kisses harder.

"If you really need that 'o'," he spun me around to face him, "we have a couple hours before the wedding."

My heart was beating in my cheat faster than it was last night. I wanted him to leave for even suggesting that. But at the same time I wanted to pull him back into my bed even more.

"No," I took a step back. "You're an arrogant jerk and you're my stepbrother!"

"An arrogant jerk, maybe," he smirked. "But I'm not your stepbrother yet," he took my hand, "they won't be married for about four hours," he led me to the bed and sat down on it.

I stood there in front of him unable to resist. I had wanted him so badly during rehearsal it was killing me inside. I placed my legs on either side of him and reached in the back to unzip my dress. Peter pushed it off my shoulder slowly kissing down my arm. "I suppose one last time wouldn't hurt anyone," I smiled at my excitement bubbling forth.

I climbed off letting my dress fall to the ground before he pulled me back to onto him. "In that case," Peter pressed his lips to mine, "let me make you happy, Susan," he smirked before flipping us over.

And that was exactly what he did. He made me happy, very happy. In fact I got very happy not just twice but three times. We were both panting and coming down from our thrice over happy state when I glanced back at the clock.

"Dammit," I rolled off of him and ran to my drawer. "The reason for me coming back home was to make myself decent."

"Lauren babe, you are more than decent," he chuckled while lying down on my bed with that smug smile staring up at my ceiling. I reached down onto the floor where his pants was and threw it at him. "Oh, you weren't talking about your bedroom experience?"

"Come on, the wedding is in an hour," I hurried to the bathroom and tried to do something with my hair. As I was ruffling it, I felt another pair of hands go through it.

"I like your hair like this," he mumbled.

How the hell did he make me feel this way so quickly? His hand was reaching back around and skimming the top of my underwear. "No," I bumped him back. "Wedding, getting dressed, you out," I motioned to the door. "And stop being hot."

"You think I'm hot," he smirked from the doorway.

"Just go and get ready," I pushed him out and turned back to the mirror in horror. What do I tell my mom? Sorry about my hair, mom. My new step brother was running his fingers through it as I rode him on my bed. "Oh God," I rolled my eyes.

"Hey, you better not be doing anything kinky in there without me," Peter called.

Why did he have to be such a jerk about it?

My mother tapped her wrist as if there was a watch there when we both arrived at the church. There was fifteen minutes left until the wedding started. "I thought you were going to fix your hair?"

"I don't know Katherine, I think it looks nice," Peter said with his arm still wrapped around my shoulder.

"Peter you can call me 'Mom' you know," she offered.

"No," I shouted causing a few people to look at me. "I mean," I said softer as Peter's smiled just grew wider.

"Well, I just want us to be one big happy family. I hope that the two of you had a chance to bond," my mother smiled.

"We did," he replied, "we really did bond."

"Argh," I groaned in annoyance praying myself away from him to help my mother out with puffing out her dress, putting on her pearls or any last minute arrangements. My mother was truly a beautiful and kind woman. I could see why she attracted men. Despite her age she was going to make one gorgeous bride today. I almost envied her.

"Let's get a few family photos in before the ceremony starts," my mother called Clark over.

As much as I didn't want to, my mother made Peter and I take a couple pictures with just the two of us.

"Lauren, at least try to look happy," mom scolded.

"I am."

"Smile for the camera and I'll make you smile later on," Peter teased at her side which got a punch to his arm. It wasn't a slap, it was a punch and he stumbled a bit rubbing his arm.

"Lauren," her mother warned. "Is that any way to treat your baby brother?"

"Baby brother," I questioned. "Wait how old are you," I turned to Peter.

"Twenty-six," he looked at me confused.

I let out a sigh. "I'm twenty-eight."

"This day just gets better and better doesn't it," he said pulling me back to his side as we smiled for one last picture. "I wonder what to call you now. Do I call you Susan, Lauren," he paused and then shot me a glance, "Cougar?"

Typical of a younger sibling to irritate you endlessly, I thought as we got ready to walk down the aisle. Susan run up quickly to me to take a quick selfie shot and ask me how I was doing.

"I am about to lose my mind," I told her.

"What happened to finding someone who made this weekend bearable," Susan asked.

"That someone is here," I muttered.

"What," she smiled and looked around.

"This isn't funny."

"Oh no, you're right. This is hilarious! Who is he? Where is he?"

"Line up, line up," my Aunt scolded as I told Susan we would talk later.

I had found Bruce with the intention of making today seem less stressful. And although it worked at first, no one told me that Bruce from last night was going to end up being Peter, my new step brother. My new younger step brother at that. He was getting on my nerves. I hardly doubt that there was a kind bone in his body. It was a surprise when he took my arm and patted it gently causing me to look up at him.

"Don't worry. My father is a good man who loves your mother dearly."

"It's not that," I repeated looking towards his dad standing there at the end. "I'm just..." I let out a deep sigh.

"What is it," he asked quietly and for that brief moment I felt the concern and care from a guy I had not felt in a while.

"These things always work out for my mother," I twirled my bouquet.

"You're wondering why it hasn't for you," he asked as I nodded. "Don't worry about that either, Lauren," he said softly causing me to look up at him. "You're a nice girl," he smiled gently.

"Thank you Peter."

It was a touching moment until he had to go and spoil it.

"Who knows, you might get lucky tonight," he said before linking my arm with his and heading down the aisle.

It was a beautiful ceremony and an even more beautiful reception. I had a blast, aside from the fact that Peter and I shared not one but two slow dances together. And not to mention that he followed me wherever I went.

Susan stared at us as we bickered back and forth until she took my hand and said that we had to use the restroom. We ended up passing it and continuing on towards a gazebo out in the garden.

"What's going on," I questioned.

"I might ask you the same thing."

"What do you mean?"

"You and your step-brother," Susan said with a small smile. I groaned and closed my eyes. "It's him isn't it? He's the one you met last night at the charity ball!"

"Sh," I told her and took her hand leading her further away from a group that was nearby. "How could you tell?"
