"Paul I can't talk now" Casey said in a low voice.

"Why? Are you with him?" Paul asked

"Oh my god, you know what? I really don't want to talk to you right now, I have to go" Casey said rolling her eyes.

"Just tell me if you're seeing him."

"Goodbye Paul" Casey said frustrated and closed her phone. "Sorry about that" she said looking over at Tommy.

"No problem" Tommy said as he finished off his beer.

"So that movie offer still any good?" Casey asked smiling. She needed to keep her mind off of Paul right now. She hated when people accused her of cheating. She needed a release and if a one-night stand was it so be it.

"Yea, its always on the table" Tommy said smiling.

"Good, lets go" Casey said as she got off her chair. Tommy pulled out money and paid for both of their drinks.

They sat next to each other on his couch watching a movie.

"So you finally realized that Paul is a dick?" Tommy asked smiling looking over at her.

"Something like that" Casey answered smiling looking over at him.

"Can I ask you a question?"

"Sure"

"Is this a one night stand? A friends with benefits or something more?" Tommy asked smiling.

"I…I haven't made up my mind yet" Casey said smiling flirtatiously.

"What if I help you out there" Tommy said smiling and leaned in and lightly kissed her on the lips. She completely melted since Paul's kissing was always so quick and fast. Tommy's kissing was slow and gentle. Casey kissed him back and lightly brought her hand up to his chest.

After a while she pulled away "Maybe we shouldn't do this, I mean I known you for a long time and I will know you since I know your uncle and it might be weird when we see each other" Casey said as she removed her hand from him.

"It wont be weird and no one has to know, trust me," Tommy whispered and gently took the back of her neck and gently pulled her closer to him and lightly kissed her cheek. Her whole body tingled with how gentle his kiss was.

"Maybe we shouldn't" Casey whispered as he gently kissed her neck.

"If you don't want to because you don't then we wont but if you don't want to because your scared Mark or Olivia will find out then don't be scared cause they wont know anything" Tommy whispered as he kept close to her face and looked into her green eyes.

"Ok" Casey whispered and moved closer to him and kissed him. He kissed her back and placed his hands on her waist. She grabbed his shirt and pulled it off. She smiled looking at his tight abs and his tattoo on his lower abdomen that she found extremely sexy.

"Its ok" Tommy reassured her and slowly took off her shirt. She nodded and kissed him again.

They fell asleep together on the couch with only a blanket covering them. Tommy's arm was around Casey's body and holding her. Casey's head was resting on his chest and her arm around his stomach. They woke up to a knock on the door.

"What the hell" Tommy mumbled waking up slightly. Casey woke up when she heard another knock on the door.

"Tommy its Mark, c'mon man get up" They heard Mark's voice at the door. Both of them quickly jumped up.

"My room" Tommy whispered as he grabbed his boxers and pulled them on quickly. Casey took the blanket and wrapped it around her body and went to Tommy's room and quietly closed the door as Tommy ran to the door and opened it.

"Hey Mark, what are you doing here?" Tommy asked standing in the doorway.

"I came to get something. Why are you so happy early in the morning? Did you have sex?" Mark questioned smiling coming into the apartment. Tommy quickly ran in front of him seeing Casey's clothes by the couch.

"What are you doing?" Mark asked as he stopped.

"What do you need, I'll get for you" Tommy said standing in front of him and making sure he couldn't see the floor by the couch.

"I need to burrow your laptop for Chicago, mine doesn't want to work. Are you ok?" Mark questioned raising an eyebrow.

"I'm cool, why don't you get something to drink in the kitchen and I'll get it for you" Tommy said smiling.

"Yea, sure, whatever" Mark said looking at him weirdly and went to the kitchen. Tommy quickly grabbed Casey's clothes and ran inside his room and closed the door.

"He didn't see them, did he?" Casey whispered.

"No, I don't think so" Tommy whispered as he handed her the clothes.

"Hey Tommy?" They heard Mark's voice.

"That bastard" Tommy whispered "What?" He called out.

"Tell the girl you're hiding in there that her bra is still here" Tommy smacked his head when he heard that.

"You forgot my bra?" Casey asked running her hand threw her hair.

"He can't figure out its you by your bra" Tommy whispered rolling his eyes as he grabbed his laptop and went out his room.

"Why can't I meet her?" Mark asked sipping orange juice and pointing to the bra on the floor. Tommy picked up the bra from the floor and put it behind his back.

"Um…she's more like a one night stand thing so I don't want you to meet her. Here is my laptop, enjoy Chicago and get the hell out of my apartment" Tommy said handing Mark his laptop and pushed him toward the door.

"Is she ugly? That's why you don't want me to meet her?" Mark teased smiling as he placed his juice on the kitchen countertop and walked to the door.

"No she is hot, now go, liv is waiting" Tommy said as he opened the door.

"But…" Mark started.

"Go. I'll see you in three days, enjoy your time off, don't get drunk, and say hi to liv, I covered all the basics. Now go" Tommy said and pushed him out the door.

"If this is the way you are after sex no wonder you only have one night stands" Mark teased smiling. Tommy rolled his eyes and slammed the door closed. Mark knocked again.

"What?" Tommy asked in annoyance opening the door.

"Have you seen Casey cause she's supposed to be at our place cause our plane leaves in a couple of hours?" Mark asked

"No, I haven't seen her, why would I see her early in the morning?" Tommy asked as he started getting nervous.

"Yea your right, I'll just call her, see you later" Mark said as he pulled out his phone and dialed the number.

"No" Tommy yelled out knowing if it rang Mark could hear she was in his bedroom. "I mean she's probably on her way, you don't want her to talk on a phone while she's driving"

"Yea your right" Mark said as he closed his phone "Are you ok?" He questioned.

"I'm cool, enjoy your trip" Tommy said smirking.

"Ok, thanks for the laptop, see you in three days" Mark said and walked down the stairs. Tommy closed the door and let out a deep breath. He went over to his room to let Casey know she could come out.

"He's gone," Tommy said as he opened the door.

"Ok, I better get going so maybe I can beat him to his house and he wont suspect anything" Casey said as she took the bra from Tommy's hands and put it on.

"So did you make up your mind?" Tommy asked smiling as she pulled on her shirt.

"Friends with benefits. Bye" Casey said smiling as she gave him a kiss on the cheek and walked out of his room.

"See you later friend" Tommy called out smiling as he grabbed a pair of his jeans.

"Bye" Casey called back and left his apartment.

She got to Olivia's house half an hour later. She walked in and Mark and Olivia were by the sink making out.

"Can't even wait a couple of hours for a hotel room," Casey teased. They quickly stopped and moved away.

"You're late" Mark said as he wiped his lip. "And your wearing the same clothes as yesterday" He said smirking looking at her jeans and shirt that she was in yesterday.

"So?" Casey said rolling her eyes.

"Did my Casey get lucky last night?" Mark teased as he put his arm around her shoulder.

"None of your business, now go to Chicago" Casey said smirking and pushed his arm away. Mark came closer and smelled her clothes "Are you sniffing me?"

"Yea she got lucky last night, I can smell the guy cologne on you. Smell her," Mark said looking at Olivia and pointing to Casey.

"I'm not going to smell my friend. C'mon" Olivia said smiling and took his hand and pulled him to their bedroom.

They grabbed their bags and came out so they can catch their flight.

"You two be good ok?" Olivia said as she gave James and Jenny a kiss.

"We will" Jenny said as she gave her a kiss.

"Have fun" James said as he gave her a kiss.

"We will," Mark said giving him a kiss. "Jenny you better watch it with Chris cause I have James to tell me everything, ok?" Mark said giving Jenny a kiss.

"Oh god" Jenny mumbled as she gave Mark a kiss.

"You two misbehave and Casey will tell us. If you need anything, both of our phones are on" Olivia said as she opened the door. Casey, James, and Jenny all just nodded as Mark and Olivia went out of the house.

They sat on the plane next to each other with Olivia resting her head on Mark's shoulder and his hand on her knee.

"Are you sleeping already?" Mark asked as he kissed her forehead.

"I'm not sleeping, I'm dozing off for a couple of minutes" Olivia mumbled with her eyes closed.

"Your sleeping baby" Mark said smiling and lightly squeezed her knee. She slapped his hand.

"That hurt." She said smiling.

"No it didn't you liar you just wanted to slap my hand," Mark said smiling as he slapped her knee. "That probably hurt"

"That did hurt" Olivia said smiling and playfully pushed him. He just smiled and wrapped his arm around her shoulder. She smiled and rested her head on his chest and closed her eyes again.

"You want to have sex in the airplane bathroom?" Mark whispered smiling.

"Baby I don't have sex in our bathroom what makes you think I would do it in an airplane bathroom." Olivia whispered smiling with her eyes closed.

"Cause were over another state border," Mark said smiling.

"Not going to happen buddy," she said as she snuggled closer to him. He smiled and held her as she got comfortable.

"Detective is already sleeping?" A voice by them said. Olivia opened her eyes and looked up to see who it was at the same time Mark looked up.

"Stupid Trevor" Mark mumbled smiling when he saw Trevor Langan standing by them.

"I was on my way to the bathroom when I saw you guys so thought I say hi" Trevor said smiling.

"You going to the reunion thing also?" Olivia asked.

"Yea, so I guess we have to see each other even on our days off" Trevor answered.

"Guess so" Olivia said smiling.

"Isn't this cute we have our own precinct reunion?" Mark teased smiling. Trevor and Olivia just rolled their eyes. "I'm going to the bathroom cause Trevor reminded me I need to do that," Mark said as he removed his hand away from Olivia and got up.

"Fine, you go first then I'll go" Trevor said as he sat down in Mark's seat.

"Don't try to steal my wife or I'm putting whip cream down your pants at the reunion" Mark warned and walked away. Olivia just chuckled and looked out the window.

"You two staying at a hotel?" Trevor asked as he opened some pamphlets that were in front of him.

"Yea. You?" Olivia asked looking over at him.

"Yea because a lot of our friends are going to stay their and just to warn you a lot of pranks will be played tomorrow especially on Mark since he did pranks a lot during our senior year" Trevor said smiling.

"Just don't get me involved and I'm fine" Olivia said smiling.

"How are the twins?" Trevor asked as he put the pamphlet back.

"They're good, both of them are starting to walk and slowly babbling words," Olivia answered smiling.

"Stop hitting on my wife I know she is hot but she's mine" Mark said smiling as he came back.

"Yea, yea, I'll see you guys later" Trevor said as he got up from his seat and went to the bathroom. Mark sat down and took Olivia's hand.

"I'm sleeping now and don't bother me" Olivia mumbled as she rested her head on his shoulder.

"Ok I wont, goodnight buddy" Mark whispered as he gave her a kiss on the cheek and opened a magazine and started to look threw it as she slept on his shoulder.

After an hour Olivia woke up to people laughing. She opened her eyes and saw Mark and Trevor talking.

"She's up," Trevor said smiling and pointing to Olivia. Mark looked over at her and smiled.

"You had a nice sleepy?" Mark teased in a baby voice.

"Yes except for you two waking me up" Olivia mumbled and on purpose slapped Mark on the knee. Trevor laughed as Mark groaned and he rubbed his knee. "What are you guys talking about?" She asked as she sat up and put her hair in a ponytail.

"Planning our pranks were going to pull on our so called friends" Mark answered smiling.

"How nice of you two" Olivia said smiling as she took Mark's hand again.

"All passengers please take your seats we are about to land in Chicago."

"I better go before I get in trouble by a flight attendant, see you later" Trevor said smiling as he walked away to his seat.

"Was I a good pillow?" Mark asked smiling as he buckled his seatbelt.

"Yea, you're an excellent pillow," Olivia said smiling as she buckled her seatbelt and rested her head back on his shoulder as she wrapped her arms around his. He just smiled and placed his hand on her knee.

They got to the hotel around 8 at night. Mark was carrying Olivia on his back and carrying their bags.

"What am I your freaking bellhop now?" Mark asked as they walked in the hallway for their room.

"The bellhop gets a tip" Olivia whispered and lightly nibbled on his ear. Mark just smiled and slid his key into the door and opened it and closed it with his foot.

"Let's see what kind of tip you got" Mark said dropping the bags and playfully throwing her on one of the beds and jumped on the other bed and started jumping up and down.

"Your like a little kid" Olivia said smiling lying on the bed and watching him.

"C'mon this is like a tradition when you come into a hotel because it's not your bed" Mark said smiling as he jumped over to the bed were Olivia was lying on. But as he jumped to her bed at the same time Olivia sat up and he stepped on her knee and fell on to the bed.

"That hurt, you jerk" Olivia groaned and punched him on the shoulder and started rubbing her knee where he stepped on it with his shoe.

"Why did you move?" Mark asked rubbing his shoulder where she punched him.

"Shut up, it really hurts" Olivia whined

"I'm sorry baby," Mark said as he sat up and rubbed her knee for her. "I didn't mean to" he whispered as he sat on top of her and massaged her knee.

"I know you didn't mean it but it hurts like hell," she said as she rubbed his shoulder where she hit him. "Sorry I punched you," she whispered.

"Hmm I think we need to take a better look at this knee," Mark said smiling and slowly unbuttoned her jeans. "I'm a doctor trust me" Mark said smiling and pushed her down on the bed. She just giggled as he pulled down her jeans and started kissing her legs and knee and came up to her stomach and pulled up her shirt.

"I think I need to look at that shoulder injury," Olivia said smiling slowly pulling up his shirt. He smiled and took off his shirt and threw it on the ground and then unbuttoned her bra. They just smiled and kissed each other since they finally had a room all to themselves.

They fell asleep around 2 in the morning with only a blanket covering them. Mark was holding her with both of his arms around her stomach. Olivia had her hands over his and was snuggled close to him.

Mark woke up at 10 in the morning and just watched her sleep for a couple of minutes. He slowly started planting small kisses on her shoulder to wake her up.

She smiled and kept her eyes closed. "Hey you" She whispered.

"How did you sleep?" Mark whispered kissing her cheek. She smiled and turned around to face him.

"Finally getting at least 8 hours of sleep is very good," She answered smiling.

"Finally having our own room is very good," he said smiling as he slowly started kissing her. She smiled and kissed him back.

They heard someone slid a key through their front door and couple of people whispering and laughing. Olivia just looked over at Mark. He took the blanket and covered her head and just buried his face into the pillow. Seconds later he felt a bucket of water over his head and a bunch of guys start laughing hysterically.

"Good morning gentlemen," Mark said smiling and ran his hand through his wet hair. Olivia uncovered her head and saw Mark completely soaked. She could feel that some of the water was on her but she just smiled.

"I guess you're his wife?" One of the guys asked smiling.

"Yea, hi" Olivia said smiling and slightly waving at the three guys in her room.

"Baby this is Mike, Gary, and Derek. Boys this is my wife Olivia" Mark introduced pointing to each guy and then at Olivia.

"Trevor wasn't kidding when he said you were hot" Gary said smiling and threw Mark's boxers on his bed and a card "Billy's room key, thought you might want to wake him up"

"How did you get in my room?" Mark asked as he pulled his boxers on under the soaked sheets and took the room key.

"Gary knows the owner of the hotel so we stole the key" Mike answered smiling proudly.

"Hey Jerks" Trevor yelled out running into the room and sprayed all three guys with shaving cream and ran out the room.

"You're so dead Langan" Derek yelled and ran after Trevor. Gary and Mike quickly followed and chased Trevor.

"This is going to be a fun day," Olivia said laughing.

"Oh yea, want to join me in waking up Billy?" Mark asked as he got out of bed and grabbed Olivia's Jeans and a t-shirt and handed it to her.

"No" Olivia answered smiling as she pulled on her t-shirt.

"Air horn. It's fun," Mark offered again as he pulled out two air horns from his bag.

"That's mean" Olivia said pulling on her jeans.

"They are going to bring you into the prank war like it or not, I suggest you team up with me." Mark said as he pulled on his own jeans over his boxers.

"Fine" Olivia said smiling as she took an air horn.

Trevor ran into their room covered in shaving cream.

"Mind if I team up with you guys?" He asked wiping his face.

"Sure, were going to wake up Billy" Mark said smiling and threw him the key card.

"Hell yea, lets go" Trevor said as he walked out of the room.

"This is so mean" Olivia said smiling as she followed with Mark right behind her.

"It won't be mean once they start pulling pranks you" Mark said smiling as they walked down the hall.

"Ready?" Trevor asked putting the card in the door. Mark just nodded. Trevor slowly opened the door and Mark and Olivia followed.

Trevor went on one side of Billy's bed and put shaving cream on his pillow around his head. Mark went by the other side and Olivia went by Trevor. Both of them put the air horns by his head and looked at each other and smiled and pressed the button.

Billy quickly jumped up and got himself covered in the shaving cream that Trevor put near him.

"Morning sunshine" Mark said smiling.

"Assholes" Billy muttered angrily and threw the shaving cream at Trevor. "I wanted to team up with Mark. Who's the chick?" Billy asked looking at Olivia.

"My wife. Billy this is Olivia, Olivia this is Billy" Mark introduced.

"Who do I get for my team?" Billy asked

"Us" A girl said coming into the room being followed by another girl.

"Brittany and Jill, aren't you lucky" Mark said smiling.

"Mark, Trevor, and I'm guessing Mark's wife since Derek told me he got married" Jill said waving at each one.

"Yea, Olivia Benson" Olivia said smiling.

"Can I get a hug?" Mark asked smiling walking over to the girls.

"Sure" Brittany said smiling and hugged him and grabbed his shirt and pulled it over his head and threw it to Billy who wiped the shaving cream with it and threw it back to Mark.

"That was mean, I just wanted a hug," Mark said pouting and holding his shirt in his hand.

"Aww poor baby, now get out so we can talk to Billy since he's on our team" Jill said and pushed Trevor out of the room. Brittany pushed Mark out the room.

"We won't push you since you have to spend the rest of your life with Mark" Brittany said smiling at Olivia. Olivia laughed and followed Mark and Trevor outside.

"Anderson, Langan" Someone behind them said. Trevor and Mark turned around only to find maple syrup squirted in their faces.

"Nice real nice" Mark said as he wiped his face.

"Hey Olivia?" Derek said smiling. Olivia looked over at him. Derek grabbed a bunch of pancakes he had behind his back and threw it down her shirt and ran away. Olivia smiled and removed the pancakes from her shirt.

"I'm going to take a shower in my room, I'll meet you guys later" Trevor said as he walked down the hall to his room.

"Lets go take a shower" Mark said smiling as he took Olivia's hand and walked with her down the hallway to their room.

"Mark" Someone called behind them. Both of them stopped and turned around. Brittany and Jill were walking over to them.

"We give you Billy and you give us Olivia for our team" Jill offered.

"No way" Mark said smirking and shaking his head.

"C'mon, guys against girls" Brittany suggested.

"You want to be on their team?" Mark asked looking at Olivia.

"I don't mind, I would like to pull some pranks on you" Olivia said smiling.

"Fine, you can have liv on your team, but right now I need to take a shower with the enemy" Mark said smiling as he put his arm around Olivia's shoulder.

"Ok, meet us in room 218" Jill said as her and Brittany walked away.

"You're my enemy" Olivia said smiling and jumped on Mark's back for a piggyback ride.

"You'll like Jill and Brittany, they're real bad asses like you" Mark said smiling as he carried her to their room so they could take a shower.

By 3 in the afternoon everyone messed up each other's room during their pranks. Olivia sprayed silly string down Marks pants. Mark poured yogurt down her shirt.

All three teams sat at in a park separated into their teams as they ate lunch.

Olivia took a sip of coffee and quickly spit it out and looked over and saw Trevor and Mark give each other a hi-five.

"They switched your sugar with salt?" Jill asked smiling. Olivia just nodded.

"Get them back" Brittany said smiling and pushed the ice cream they had by them toward her. Olivia smiled and put it behind her back and went toward Mark, Trevor and Billy.

"Hi sweetheart" Mark said smiling looking up at her.

"Hi" Olivia said smiling and poured the ice cream right on Mark's groin.

"Cold, cold" Mark shrieked as he jumped up and shook off the ice cream off. Olivia just laughed and started walking back to Jill and Brittany.

Mark ran after her and grabbed her from the back and lifted her up in the air by her waist. She laughed and started kicking to get out of his grip.

"Mark! Let go of me!" Olivia screamed laughing hysterically.

"No way" Mark said smiling as he placed her on his shoulder and slapped her butt.

"Put me down!" Olivia yelled laughing and hitting his back. "Please put me down baby?" Olivia asked laughing hysterically.

"Apologize for putting ice cream on my manhood first" Mark said smiling still holding her on his shoulder.

"Never" Olivia said smiling.

"Apologize" Mark said smiling and slapped her butt again.

"Never ever infinity never" Olivia said smiling and slapped his butt.

"Hey, hey detective watch your hands there" Mark said smiling.

"Mark please put me down sweetheart" Olivia said smiling.

"No, I like you like this, I get a perfect view of your nice ass" Mark said smiling and gave her a kiss on her butt. Olivia smiled and pulled up his shirt and grabbed his boxers and pulled.

"Oh god" Mark yelled jumping a little.

"Put me down or I pull more" Olivia threatened smiling still holding his boxers. "Or if you don't put me down now you wont get sex tonight which means no sex in New York because of the twins" Mark put her down immediately.

"I love you" Mark said giving her a kiss.

"I love you too," Olivia said returning the kiss and going back to sit with Jill and Brittany.

"You two are so cute together," Jill said smiling as she ate her sandwich.

"How did you guys meet since he's FBI?" Brittany asked.

"Oh, I'm a detective for NYPD so we met when I went to the FBI building for a case" Olivia answered.

"Detective for what?" Jill asked.

"SVU"

"Oh wait are you telling me that you go against Trevor since he is a defense attorney?" Brittany asked smiling. Olivia smiled and nodded.

"Oh ladies" Derek said coming behind them. All three girls turned around and Derek and Mike poured Pepsi all over them as Gary poured it over Billy, Mark, and Trevor.

"Mike you jerk, that's it no sex for you!" Brittany yelled. Olivia just looked at Jill.

"They're dating" Jill explained smiling. Olivia smiled and nodded.

"Mark your wife gave my girlfriend an idea how to get me back, that's not fair" Mike yelled at Mark.

"Oh shut up, she'll get over it, I cant have sex till my kids are 2 and they move out of our room" Mark yelled back as he got off the grass and walked over to Olivia.

"Lets get going and take a shower cause the reunion party starts at 7" Jill suggested as she got off the bench the girls were sitting on.

"C'mon enemy" Mark said taking Olivia's hand and letting her jump on his back "We'll see you guys later" Mark said as he carried Olivia to the hotel.

"Your cute when you're covered in soda" Olivia teased as she gave him a kiss on the cheek.

"You want to lick off the ice cream?" Mark asked smiling.

"Ha, you wish babe" Olivia said smiling as they got to their room. "You get in the shower and I'm going to call the kids to check up on them and I'll meet you there" Olivia said as she jumped off his back.

"Ok you got it" Mark said giving her a kiss as he took off his shirt and went to the bathroom. Olivia took off her shirt and threw it on the ground as she dialed their house phone.

"Hello"

"Casey?"

"Yea, Olivia?" Casey asked mockingly.

"Shut up, I thought the kids would answer it" Olivia said smiling.

"James is skateboarding and Jenny is with Chris"

"You didn't let her go with Chris alone did you?"

"No, they are in the backyard and James is keeping an eye on them even if I told him not to bother them"

"Oh ok, cause Mark would kill you if you let them go" Olivia said smiling as she walked around the room.

"Oh I know, you guys having fun?"

"Yea, actually you know that Trevor is here also"

"Trevor Langan?"

"Yea, he's actually really nice"

"Oh are you trying to hook me up with a defense attorney?" Casey teased

"Not hook you up but just letting you know he is nice, anyway tell the kids we said hi cause I got to go take a shower cause we need to go to the reunion party soon"

"Ok, don't get drunk, bye"

"Bye" Olivia said smiling and closed her phone.

She went to meet Mark in the bathroom. She opened the door and then opened the curtains but he wasn't there. She felt someone grab her from the back and lift her in the air.

"I'm so sneaky" Mark teased as he pulled her into the shower with her clothes on.

"Your mean" Olivia said smiling and unbuttoned her soaked jeans.

"Let me do the honors" Mark said as he pushed her against the wall and slowly unbuttoned her jeans.

"You're not going to get sex in this bathroom either" Olivia said smiling.

"Who said I was going to give you sex?" Mark asked smiling as helped her take off her jeans "Detective Benson are you trying to manipulate me for sex? Oh the shame and the horror." He teased smiling as he unhooked her bra.

"Oh shut up you dork." Olivia teased smiling as she grabbed soap.

"Not what you said last night" Mark said smiling as he kissed her neck as she soaped up his chest.

"I will say it tonight cause you don't get sex tonight" Olivia teased smiling.

"I don't care its not like I want sex from a chick who kissed one of her colleagues" Mark teased smiling. Olivia smiled and grabbed his groin "Ah, ok, ok, I'm kidding" Mark said quickly.

"That's what I thought," Olivia said smiling and let go.

"But has Sandberg bothered you since?" Mark asked as he grabbed shampoo and shampooed her hair.

"No, he tries to avoid me on all costs now, mostly cause he is scared of you and by me punching him in the face that time" Olivia answered smirking as she moved under the water to rinse her hair.

"Does he even have a girlfriend?" Mark asked as he poured shampoo on his hair.

"I don't think so," Olivia answered as she shampooed his hair for him. "I'm going to leave you in here since I need to blow dry my hair" she said as he rinsed his hair.

"Ok, can you get me my razor cause I need to shave?"

"Sure," Olivia answered as she took a towel and wrapped it around her body and went to one of his bags and got his razor. She smiled as she thought of the perfect prank. She walked back and opened the curtains and looked freaked out.

"What? What's wrong?" Mark asked getting concerned.

"I just…I just got a call from Jenny and she's pregnant," Olivia said in a worried face.

"What?" Mark yelled.

"Got 'cha" Olivia said smiling "I win prank war" Olivia yelled out and threw her hands in the air in victory.

"Oh my god, are you out of your mind, what the matter with you? I almost had a heart attack," Mark said as he let out a deep breath.

"Who's the master of pranks now?" Olivia asked smiling as she handed him his razor.

"Fine, you win" Mark said pouting.

"That's what I thought," Olivia said smiling as she gave him a kiss.

"If it was for real then don't give me a razor right after it" Mark said rolling his eyes.

"Why? You would commit suicide with your Gillette razor?" Olivia teased as she plugged in her hair dryer.

"Yes" Mark answered smiling as he put shaving cream on his face.

By 6:30 that night they were both getting dressed to go to the reunion party. Olivia occupied the bathroom so she can put on her makeup and Mark took the room so he can get ready.

"Are you ready yet?" He called as he knocked on the bathroom door.

"Give me a minute" Olivia called back.

"Your such a girl"

"Go be a guy and watch a football game as you wait on the girl" Olivia called back smiling.

"Fine, hurry up" Mark called back and went to the room and sat on the bed as he turned on the T.V.

After a while the bathroom door opened and Olivia came out in a beautiful pink dress. Mark looked up and his mouth just dropped.

"Good? Bad?" Olivia asked smiling as she turned a full circle.

"Um…you…amazing" Mark uttered in amazement and kept looking at her.

"I need you to breath sooner or later and not drool" Olivia said smiling as she walked over to him. Mark closed his mouth and got off the bed.

"You look so amazing" He whispered smiling as he placed his hands on her waist.

"Your not so bad yourself" Olivia said smiling as she wrapped her arm around his neck and looked at his at the tux he was wearing, which he looked extremely cute in.

"You think we have time," Mark asked smiling and jerking his head toward the bed.

"I'm not getting out of this and then putting it on again. Later tonight when I don't need to put it on again" Olivia said smiling as she gave him a kiss.

"Ok, you promise?" Mark asked smiling as he returned the kiss.

"Yes, trust me I really enjoy that tux on you" Olivia said smiling "but I enjoy it better when its off" she whispered softly in his ear. He just smiled and gave her a kiss.

"Lets get going" Mark said as he took her hand and led her out of their room.

"Wow, Benson looks nice" Trevor said smiling as he saw them by the elevator. He was also wearing a tux.

"Well thank you, you look nice also" Olivia said smiling holding Mark's hand.

"It's funny how you guys are nice to each other now but the second were in New York you will hate each other's guts" Mark said smiling as all three stepped on the elevator.

"We don't hate each other's guts we just disagree on certain things," Trevor said as he pressed the button for the lobby.

"Yea like on things if rapists and murders should go to jail" Olivia provoked.

"Everyone deserves a defense Olivia," Trevor argued.

"Not when you rape and kill innocent people," Olivia argued.

"Ok, wow, what happened to the whole nice vibe of Chicago, you know the windy city and all the nice things about it" Mark interrupted "Please fellow New Yorkers don't embarrass me" he said as the doors opened and he stepped out of the elevator. Trevor and Olivia just smiled and followed him to the lobby where the party was.

"Lets go see where we sit," Mark said as he put his arm around Olivia's shoulder and they walked to the table with their names.

"I got table 4" Trevor said as he found his name.

"Lets see…Anderson" Mark said as he looked at the cards.

"Mr. Anderson" Olivia said and started laughing. Mark just smiled and kept looking for his name.

"Matrix right?" Trevor asked laughing. Olivia laughed and nodded.

"I'm glad my name can amuse you two" Mark said smiling as he picked up the card with his name "Would you look at that, were sitting next to Trev" Mark said showing the 4 on their card.

They got seated at their table. Olivia and Trevor started talking about a case and Mark just looked on in amusement and time to time settled them now and made them switch to another case cause he found it funny. By that time it's was already 9 at night.

"Ok, I'm going to find someone to talk to while you two battle it out" Mark said as he got up from his chair. Trevor and Olivia kept talking and didn't notice him "Hello? Sexy man leaving the table" Mark said trying to get their attention.

"Don't worry I'm not leaving the table" Trevor teased smiling. Olivia started laughing.

"Ha Ha, your funny in Chicago. I'll be back" Mark said smirking and gave a kiss to Olivia and walked away.

"Hey Trevor" A man said coming up to Trevor and Olivia.

"Hi Eric" Trevor said as he shook hands with the man.

"She with you?" Eric asked looking at Olivia.

"No, Mark's wife" Trevor answered.

"And you're hitting on her? Aren't we a player today" Eric said smiling and then looked at Olivia "How are you sweetheart? I'm Eric, I don't mind on going an affair either," He said smirking.

"I suggest you get going before I call Mark and then he can kick your ass since I don't want to mess up my tux" Trevor said giving a look to Eric.

"Oh you want her all to yourself, sorry" Eric said smiling. Trevor said nothing and on purpose tipped the glass by him and made it spill allover Eric.

"Oh, I'm sorry, should I get Mark now or no?" Trevor asked smirking.

"Asshole" Eric said angrily and punched Trevor. Mark came from the side and punched Eric and made him fall to the ground.

A whole group of people by now turned around and watched. A couple of guys jumped Mark and Trevor jumped on them trying to pull them off of him. Derek, Mike, Billy and Gary ran through the crowd and quickly jumped in the fight.

Brittany and Jill came by Olivia and sat down by her "This happened a lot during high school, that group of guys hated us since they were the jocks, senior year the boys beat most of them up and they said they would get them back reunion" Jill explained as Mike and another guy fell by them and hit each other.

Mark tackled one guy to the ground and one guy kicked Mark. Trevor tackled that guy in defense for Mark.

Security quickly ran through the crowd of people and separated all of them.

"Gentlemen were still at it," A woman said walking up to them.

"Our old teacher" Brittany whispered to Olivia. Olivia just nodded and kept watching all the guys being held by all the security guards.

"I would suspend all of you right now but since your supposed to grown men I cant" The woman said glancing at each guy.

"Um…Mrs. Bridges they started it" Trevor said smirking. The whole crowd of people started laughing. Mrs. Bridges quickly glanced at him.

"Mr. Langan what job do you have now?" Mrs. Bridges asked Trevor.

"Defense attorney" Trevor answered.

"Mr. Anderson?" Mrs. Bridges said looking at Mark. Olivia couldn't help but giggle a little but she quickly suppressed it.

"One of the captains for the FBI" Mark answered.

"You two think you've grown up by now?" She asked looking at each one.

"I have 4 kids and a wife but I'm not sure I'm all there maturity wise" Mark said smiling. The crowd of people laughed again.

"Oh my god, you know what? I'm not even going to bother with you today, fight again and you will be thrown out. Now enjoy the rest of your night and Mark please send best wishes to your wife for having to spend the rest of her life with you" Mrs. Bridges said smirking. Mark just smiled as all the security guys let go of everyone.

"That was fun," Trevor said wiping the blood off his lip.

"High school allover again" Mark said smiling wiping the blood of his lip as they walked back to their table.

"Nice tackle Mark" Jill said smiling. Mark just smiled and sat down by Olivia.

"Thanks Trevor" Olivia said with a small smile looking at Trevor. He just smiled and nodded.

"What did he do?" Mark asked.

"That Eric guy was mean to me and Trevor spilled wine on him for me" Olivia answered.

"Where is that bastard?" Mark said looking around for Eric.

"Cool it," Trevor said giving a look to Mark.

"Fine, but thanks man" Mark said shaking hands with Trevor.

"Anyone want to get out of here and get wasted?" Derek asked coming up to the table with Billy, Mike and Gary by him.

"I'm going, Mark want to join us?" Trevor asked as he got off his chair.

"No I'm fine" Mark answered.

"Go ahead honey it's your night" Olivia said looking at him.

"No it's cool, I don't want to leave you here"

"She has us, go ahead get drunk with the boys," Jill said smirking.

Mark just looked at Olivia. She smiled and nodded. "I wont get drunk but I'll go, I'll see you later" Mark said as he got off his seat.

"You can get drunk if you want" Olivia said smiling as he gave her a kiss.

"I'll try not to. Love you" Mark said giving her another kiss.

"You too, bye" Olivia said as Mark went off with the boys.

"You and Mike had sex after the park didn't you?" Jill asked looking at Brittany.

"What?" Brittany asked smiling.

"She cant ever keep her rule of she wont have sex with him" Jill said smiling looking at Olivia. Olivia just smiled.

"Oh c'mon Mike is a cutie, even if your married to Mark admit it that Mike is cute," Brittany said smiling looking at Olivia.

"He is very charming" Olivia said smiling.

"So how big is Mark down there?" Jill asked smiling.

"Um…I really don't want to discuss that, I mean his my husband" Olivia said smiling and blushing a little.

"C'mon girl talk, the boys are probably talking about sex as we speak I mean their guys. We wont let them know we talked about this" Brittany said smiling. "It's just girl talk"

"Um…he's very lengthy" Olivia said smiling. Jill and Brittany just laughed.

"Less then 5 or more?" Brittany asked smiling.

"More" Olivia answered smiling. "What about Mike?"

"Semi big, like 5 or 6 inches" Brittany answered. Olivia and Jill just laughed.

The boys sat at a bar and did shots.

"One night stand. Jill, Brittany, or Olivia?" Derek asked.

"Oh come on that's my wife" Mark said as he took a shot.

"Jill" Billy answered and did a shot.

"Olivia" Gary answered doing a shot.

"Hey!" Mark yelled.

"What? It's a one night stand," Gary said smiling.

"I go with Brittany" Trevor answered

"Hey!" Mike yelled.

"What? It's a one night stand," Trevor said smiling and gave Gary a hi-five.

"Mark?" Derek asked.

"I plea the 5th amendment" Mark said smiling.

"Were not in court," Billy said rolling his eyes.

"Ok, Olivia" Mark answered.

"Liar" All the guys yelled at the same time.

"Ok, Brittany because I would want her just for sex cause she is hot but Olivia overall cause she is an awesome woman" Mark said smiling.

"C'mon dude your talking about my girlfriend" Mike yelled defensively. All the guys laughed and took a sip of their beers.

Olivia got to their hotel room at 1 after her and the girls talked. Mark wasn't there so she just went to bed. When she finally fell asleep she heard the door open and close slowly. Mark came in and literally jumped in bed. Olivia woke up instantly.

"Hey you, why are you jumping in bed and waking me up?" Olivia mumbled smiling as he hugged her.

"I love you Livvy" Mark mumbled smiling. Olivia smiled realizing he was drunk since Livvy was his nickname for her when he was drunk.

"Are you drunk?" Olivia asked smiling.

"No, you're drunk" Mark said and touched her nose.

"I'm not drunk you are" Olivia said smiling touching his nose.

"Hmm maybe I am drunk," Mark said as he flopped down on the bed next to her but kept his arm around her stomach.

"Yes you are, c'mon lets get you to bed" Olivia said as she took off his blazer for him.

"Don't undress me," Mark mumbled.

"Why?" Olivia asked as she unbuttoned his shirt.

"I don't know" Mark said giggling. Olivia just laughed.

"Time for bed you drunk" Olivia teased as she unbuckled his belt.

"I want a hug livvy," Mark said pouting and holding out his arms. Olivia smiled and gave him a hug. "Can we have sex?"

"No" Olivia answered smiling still hugging him.

"Can we make out?"

"No"

"Can we hug?"

"Were already hugging" Olivia said smiling.

"You just don't get it" Mark whined and stopped hugging her and turned to the other side. Olivia laughed and took off his shirt for him and threw it on the ground.

"I love Livvy" Mark mumbled smiling.

"I love Mark" Olivia said smiling and took off his pants for him and threw them on the ground and left him in his boxers.

"Hug Livvy" Mark said holding out his arms again. Olivia smiled and gave him a hug. Mark smiled and blew on her neck so it would make noise and tickle her. Olivia just laughed hysterically and stopped hugging him.

"I'm going to the other bed since you toss and turn a lot when you're drunk" Olivia said getting out of bed and putting the blanket over him.

"Livvy is hot" Mark mumbled and passed out. Olivia smiled and kissed his head and went to the other bed and fell asleep.

Mark woke up around 8 in the morning. He was sleeping on his stomach and his arm was on the floor. He was facing the wall and his head in too much pain from the hangover to move. He felt next to him with his other hand were Olivia normally would be but all he felt were bed sheets.

"Baby?" He called out still lying in the position he woke up in.

"Over here" He heard Olivia's voice and he could tell he woke her up by her mumbling. He slowly turned his head to face the other bed and saw she was half asleep in the other bed.

"What are you doing over there?" Mark mumbled sleepily.

"You were drunk last night," Olivia mumbled with her eyes closed.

"I wasn't mean was I?"

"No, your not a mean drunk you just toss and turn a lot when you're drunk and I didn't feel like sharing a bed with you" Olivia mumbled and wrapped the blanket around her more to get comfortable.

"Come over here I don't want to sleep alone" Mark mumbled.

"I don't want to get up, you come over here" Olivia mumbled.

"My head hurts I don't want to move" Mark mumbled back.

"I'm sleepy I don't want to move either" Olivia mumbled smiling. Mark started gagging and quickly jumped out of bed and ran to the bathroom. Olivia heard him throwing up so she got up and went to the bathroom.

"You ok baby?" She asked as she rubbed his back and grabbed a towel for him. Mark threw up again and then flushed the toilet.

"I'm sorry I got drunk," Mark said as he turned on the water and put water in his mouth.

"It's ok, I gave you permission to drink don't worry about it" She said stroking his hair as he washed his face and she handed him the towel.

"I know but I promised you I wouldn't get drunk when we got married" Mark said wiping his face.

"Don't worry about it, c'mon lets get to bed since our flight is at 3 in the afternoon" She said wrapping his arm around her stomach.

"You didn't need to get out of bed you knew it was just hangover throwing up," Mark said as he kept his arm around her stomach and they walked together to one of the beds.

"You're my husband I have to take care of you" Olivia said smiling as she got in bed and he lay down next to her.

"I wasn't mean to you last night was I?" Mark asked as he wrapped his arms around her body and rested his head on her stomach.

"No, I told you already you're an amusing drunk not a violent one" Olivia said smiling stroking his hair.

"Not the head it hurts" Mark quickly said. She quickly stopped stroking his hair and rested her hand on his back.

"Want me to get you some Tylenol?" Olivia asked.

"No, this position is soothing" he mumbled as he slowly started falling asleep on her stomach.

"Ok," Olivia whispered smiling and let him sleep as she slowly started falling asleep.

Olivia woke up at 11 and saw that Mark was still sleeping on her stomach. She smiled and grabbed a magazine by her bed and flipped threw it so she didn't move so he could sleep.

She read it for about half an hour and then felt kisses on her stomach. She smiled and looked up from the magazine.

"Your finally up" She said smiling looking at him.

"Yup, thank you for letting me sleep on your stomach" Mark said as he moved so he was lying next to her and gave her a kiss on the cheek.

"No problem, you took care of me for 9 months when I was pregnant so it's the least I can do when you have a hangover." Olivia said smiling as she put the magazine do "Now that your up I have to go to the bathroom" She said smiling and got out of bed and went to the bathroom.

Mark got up and grabbed the laptop so he can finish a report for work. He sat up against the headboard in bed and rested the laptop on his lap as he typed.

Olivia came out of the bathroom and saw him typing. She found him extremely cute when he was focused on working. She smiled and walked over to him and sat down on him in front of the computer. A knee on each side of his body and her hands holding the back of his neck.

"Baby I have to finish this cause I didn't do it last night" Mark said as he tried to get his laptop that was behind Olivia's body.

"Do it on the plane" Olivia said smiling playfully and started kissing his neck.

"Honey c'mon" Mark said smiling holding her by the waist.

"Someone promised me sex last night and then he came drunk and I didn't get any" Olivia said smiling slowly running her hands down his muscular chest.

"Get Trevor he needs a good banging anyway" Mark teased smiling still trying to get his laptop. Olivia smiled and grabbed the laptop and placed it on the floor.

"I don't want Trevor, I want you" Olivia whispered smiling and started kissing his chest.

"You want Aaron?" Mark asked smiling. Olivia smiled and pinched his nipple. Mark jumped up and wrapped his arms around her and flipped her down on the bed. Olivia screamed smiling and wrapped her arms around his neck and pulled him closer as he sat on top of her and started kissing her.

They fell asleep after sex without even realizing it. Olivia started waking up slightly and looked at her watch. 3:10

"Mark get up," She said jumping out of bed. "We missed our flight, get up" Olivia said as she shook him. He groaned and looked at his watch.

"Damn it" He cursed as he sat up in bed. "See what happens when you want to have sex in the morning" Mark teased as she threw his jeans and a t-shirt at him.

"Oh shut up and get out of bed." Olivia said as she put on her bra.

"Relax, you think being the captain for the FBI doesn't have its perks" Mark said smiling as he grabbed his cell phone "Matthews its Anderson…I'm good, I need a private jet for O'Hare airport in Chicago…ETA? 20 minutes sounds great thanks" Mark said smiling and closed his phone.

"Private jet huh?" Olivia asked smiling as she pulled on her jeans.

"Yea, c'mon lets pack this stuff up and get going." Mark said as he got out of bed and pulled on his boxers.

By 5 in the afternoon they sat in a private jet on their way to New York.

"This is fun," Olivia said smiling as she lay on the sofa in the plane.

"Told you marrying me wouldn't be so bad" Mark said smiling as he sat at a table by her typing on the computer.

"How come we didn't go to Chicago in this?" Olivia asked as she got up and sat by him.

"It's mostly for cases but I knew we didn't have any cases open today that we needed to use the plane for so might as well use it for us" Mark answered as placed his hand on her knee and typed on computer with one hand.

"Why didn't your laptop work this morning?"

"I don't know I'll get it checked when we get to New York, but when I went to Tommy's place he had a girl in his room"

"What else is new," Olivia said smiling.

"He was hiding her," Mark said smiling.

"Ok that's new"

"And that same morning Casey shows up at our house in the same clothes" Mark said smirking.

"Oh my god, she wouldn't sleep with Tommy, jeez Mark they're friends and she's older then him," Olivia said rolling her eyes.

"Ever hear of friends with benefits?"

"Yes but they're not those type of friends, its just a coincidence nothing else."

"Ok if you say so," Mark said shrugging.

"Agent Anderson were about to land in New York," The co-pilot said over the intercom. Mark and Olivia sat down and buckled up their seatbelts.

They arrived at their house at 8 o'clock that night, where they got huge hugs from James and Jenny.

"Thanks for watching them" Olivia said to Casey as she walked her to the door.

"No problem, I'll see you at work" Casey said as she went out of the house.

"Goodnight" Olivia called out and closed the door.

Casey pulled out her phone and dialed a number.

"Hello"

"It's me" Casey said when she heard Tommy's voice.

"What's up?"

"My place?"

"You got it"

"Bye" Casey said and closed her phone and headed to her apartment to meet her 'friend' and smiled at herself for keeping it a secret and was just hoping that no one would find out. Especially Mark and Olivia.
