Playing the Part

"Your what!" Brennan shouted. Lexa turned around and looked at him.

"Sweetheart, don't yell or we are going to be in a lot of trouble" lexa told him trying to sound like a loving wife. 'That's it, I'm going to get the information I want now' brennan thought, he grabbed lexa and pinned her against the wall, he kissed her hard and deep, mark turned around and saw them and for a moment he wasn't afraid to blow his cover just so he could beat that guy to death or maybe use his power on him.

Lexa couldn't breathe, God he really knew how to make a girl loose her mind, he pulled away slowly but kept on brushing his lips on hers while his hands were caressing her waist and thighs. Lexa was panting and feeling lightheaded.

"Explain everything to me, because I'm not moving until you do" Brennan told her, tracing her lips with his tongue.

"He was my partner, things changed and we ended up falling in love and then getting married, we had a couple of great months and then they found out then they punished us, broke us apart and made us get a divorce. I hadn't seen him in a long time, that's all, we should go to the diner, they are expecting us" Lexa explained trying to stay focus and not get distracted by his actions.

Brennan heard everything, he felt a bit of jealousy inside of him, he didn't like this guy or the way he looked at lexa apparently to him, she was still his. Brennan kissed her again, letting his tongue enter her mouth and caressing every corner of her mouth, enjoying her taste and making her moan. Lexa forgot the mission and the world around them, her knees went weak and she felt like she would fall, but Brennan was holding her by the waist, making sure she would stay in place. The sounds she was making, were driving brennan crazy, he wanted her, so bad, ever since she had kissed him and touched him, something had awaken inside of him, a need to have her and he didn't care if it was right here. But the sound of a strong hard voice made them break apart. Brennan turned around and found mark standing near the woman who had spoke to lexa this morning, he looked pissed and ready to kill. Lexa was holding herself against the wall, her head was spinning and her breathing was hard. Brennan was breathless and looked flushed.

"Sorry to interrupt you but we are expecting you and the diner is about to begin" the woman explained smiling.

"Sorry is just I couldn't resist, a woman like my wife makes a man do the craziest things" brennan explained, brushing his lips on lexa's and turning around to look at mark, he was looking at lexa and focusing on her eyes and lips. 'She looks great just like she used to right after we were done making love' mark thought.

"You should go back to your wife Mr. Carter, I'll take care of mine" Brennan told him and then turned to lexa. After a few seconds, she was better and looked both pissed and confused and Brennan found it very sexy, weird how much he was finding out about her in this mission, they were never able to spend time in sanctuary but now things were different. They got to the diner and sat down; when brennan looked at the table he realized they were going to be next to John and his wife. Mark smiled at lexa, when she sat down. Brennan leaned closer and whispered in lexa's ear.

"He looks at you like he can see through your clothes" Lexa laughed and whispered back.

"That's because he can, is part of his power" Brennan got pissed and turned to the guy.

"Do me a favor keep your eyes on your wife, not on mine" Brennan told him, brushing his hand on the guys' skin and letting a bit of electricity out. Mark moved his arm out of the way and looked at Brennan. Lexa found it very strange, but she had to focus on the mission, she looked at mark.

"Hey can you find a doctor with a small silver cylinder with black letters" She told mark. He smiled and winked. Then look around and found the guy, he adjusted his vision and found the object under the guys jacket.

"Second row, guy with the cigar and glasses" mark told her. Lexa found him and made sure control heard it, so they could give her the room number later. She ate her food and listened to the doctors talking. Mark kept looking at her and licking his lips, lexa knew what he was doing and the constant brush of his foot against her leg was making her nervous, she excused herself and went to the bathroom. Brennan was okay with it, the one pretending to be Mark's wife asked him to dance with her. Brennan agreed and went to dance with her. After a few seconds Brennan noticed the guy wasn't at the table anymore.

"He is probably with her, after what I heard, they must be doing it right now" The woman explained. Brennan excused himself and walked away. He was near the bathroom when he saw lexa coming out, but what he saw next made his blood boil and the amount of electricity running through his body was strong. Mark pulled lexa with him, pinning her against a wall, he looked into her eyes and then kissed her, lexa didn't stop him, this was the only men besides Leo she had truly loved, he knew everything about her and that made her vulnerable in front of him. The kiss was passionate and hard, Brennan gritted his teeth and clenched his hands into fists. She wrapped her arms around his neck and he pressed himself closer to her.

"I've missed you lex" mark told her, while he kept kissing her.

"This is wrong, we are in the middle of a mission, shouldn't we be focusing on that" lexa told him.

"I guess is wrong, but damn it feels so good, I want you so bad, ditche that idiot and meet me at room 112, there are no cameras in there and I will show you how good this can feel" Mark told her, slipping the key to the room on her hand and walking away. Brennan saw the card and heard what he said. He turned around and went to the room. Lexa went back to the table and looked for Brennan, when she didn't find him, she went to the room to see if he was there. Brennan was pissed and hurt, she had played with him enough, he knew she wanted him and he wasn't going to let her go to this guy, he turned off the lights, leaving only the night lamps, he took of his jacket and shirt, leaving him only in pants. He heard lexa approaching the room; he stood next to the door waiting for her to enter. Lexa opened the door and walked inside, she noticed the lights and found it weird, the sound of the door closing made her turn around. She found Brennan leaning against the door wearing only his pants. She swallowed hard and tried speaking but Brennan placed his finger on her lips and stopped her.

"I was waiting for you, honey, we are finally alone, no doctors or labs, is time to revive this marriage" Brennan told her, lexa assumed the cameras were on and he was playing the part, but what happened next really surprised her. He pulled her close and pulled on the string holding her dress, once the material was at her feet he lifted her up and laid her on the bed, he unzipped his pants and removed them along with his boxers, leaving him completely naked, lexa was having a hard time thinking, he looked amazing, she knew there was a possibility they would have to sleep together but not this soon, he leaned over placing a kiss on her stomach and slowly lowering her black panties, once they were gone, he crawled on the bed and placed himself on top of her. Damn the consequences, he was going to have her tonight and no one was going to stop him.
