Mine

Brennan started kissing her slowly, Lexa didn't stop him. She was enjoying it, he would lick and suck her lips making her whimper, he pulled away to trail kisses from her jaw line to her neck, licking and biting her skin. He wanted her to want him as much as he wanted her. Brennan didn't liked being played and right now he wasn't thinking he was just acting. His hand cupped her breast squeezing it, making her gasp; he used his finger to tease the peak and make moan loud. Lexa threw her head back and gripped his shoulder. Brennan kept playing with her body and enjoying the sounds she made, he pulled away from her neck to kiss her chest and capture one of her breasts with his mouth, swirling his tongue around the nipple and sucking on it.

He didn't let her move, he was loving this side of her, she looked vulnerable and completely at his mercy. He kept going lower with his lips licking, kissing, biting every inch of skin he found, he was right above her core, when his eyes locked with hers he smiled before flicking his tongue against her sensitive area making her whimper, he explored her with his tongue drowning in her taste, Lexa kept saying oh god over and over, she wanted to scream his name not the one he was using for his cover but the real one, but she knew she couldn't. He was driving her crazy every touch of his tongue was bringing her closer to the edge, he pulled away and kissed his way to her breasts, he leaned closer so he could continue teasing her nipple with his tongue while his hand moved to her entrance.

He bit slightly hard on her nipple while inserting a finger in her center. He licked it to sooth the bite and inserted a second finger while rubbing her clit with his thumb.

"Oh God" Lexa moaned. He pulled away to start a trail of kisses, licks and small bites from the space between her breasts to the spot between her hip and thigh. He breathed the scent of her arousal and smiled. She was his completely.

Before she could say his name, he slipped his tongue past her lips to her clit. She arched her body against his mouth loving the sensations of his tongue against her.
She clutched the sheets at the sensation his tongue caressing her insides was provoking. He tasted her while his fingers moved in and out of her. She threw her head back against the pillow. He knew she was close by the constant movement and the sound of her moans. He placed a hand on her hip to keep her still and increased his speed when he felt her inner walls fluttering around his fingers.

"I'm going to……" Was all Lexa managed to say before waves of pleasure coursed through her body.

"Let go" Brennan said when he felt her body trembling. She screamed his name as she came. He didn't pull his fingers out until he felt her body calming down. She opened her eyes and looked down at him. He kissed his way back up her body to end on her lips. She kissed him hard with passion and desire. He pulled away and he placed himself between her legs, Lexa could feel his length near her entrance and at this point she wasn't thinking anymore.

"Do you think the cameras are still on?" Lexa asked out of breath.

"They were never on" Brennan replied sucking on her lower lip and moving his hips so she could feel him. Lexa stared at him and Brennan knew he had to ask.

"Do you want me to stop?" Brennan asked, licking her lips. Lexa closed her eyes for a moment but then she looked at him and smiled.

"No don't stop" Lexa replied. The words were barely out of her mouth when Brennan entered her in a deep thrust making her cry out in pleasure.

"God Lexa, you feel so good" Brennan gasped going deeper. Lexa was clutching the sheets and trying to reply but there were no word coming out of her mouth only, moans and whimpers. He kept going in and out, faster harder and deeper; Lexa felt like she would break apart from the sensations, there was nothing stopping them. She started to scream his name and dig her nails on his back. This made Brennan groan and bite her neck. He started massaging her breast with his hand, while his mouth was devouring her neck and his thrust were increasing and getting harder.

"Brennan, don't stop, go harder and faster" Lexa told him, she was panting and couldn't for the words correctly. Brennan had always been really possessive and it usually came out while having sex. He started to go slower, knowing that this was going to drive her crazy. Lexa tried to move so he would go faster, but he held her down going extremely slow.

"Brennan please" Lexa begged gripping his shoulder.

"Say you're mine" Brennan told her, thrusting in slowly until he was buried inside her.

"OH God" Lexa gasped. Brennan didn't move he stayed there, just sucking on her lips and looking into her eyes. She tried to move her hips because the pressure was too much.

"Say you're mine Lexa" Brennan told her, pinching a nipple. She cried out and threw her head back.

"God I'm yours Brennan, I'm yours" Lexa shouted. As soon as the words were out of her mouth Brennan started to go as fast as he could, making his thrusts hard and deep, she kept screaming his name and saying she was his and Brennan kept panting the words mine into her mouth. She started to clench her walls and her whole body trembled with her orgasm. She screamed his name, arching her back so hard. Brennan didn't stop until her body was calming down. She started to breathe and opened her eyes; she looked at him and kissed him hard.

"You didn't" Lexa was saying, when he placed his finger on her lips, silencing her.

"I'm not done with you just yet" Brennan told her. And continued to thrust inside her, this went on for a few hours, Lexa couldn't believe the way Brennan was acting, he was very possessive and demanding, but at the same time a very sweet and considerate lover. She lost count of how many times he made her come before he came. They ended up falling asleep in each others arms completely satiated.

The next morning Brennan woke up first and at first felt completely lost until he felt the warm of her body next to his. Her head was on his chest and she was sleeping peacefully. He threw his head back and remembered everything they had done the previous night. He had been with a lot of woman in his life, but the connection he felt last night with Lexa was unique. The way she had reacted to his touch, the fact that she kept up with him pleased him so much. She was an incredible lover, at some point during the night she had taken control and it had been his turn to scream her name and clutch the sheets. He didn't want this mission to end or let Lexa go. Marl probably wanted her back but he was giving her up without a fight. She started to move and he looked down, to see her opening her eyes, the fact that the woman could kill him with her power made Brennan swallow hard.

Lexa opened her eyes and felt a body underneath her, and then a series of very erotic and pleasing images came to her head. She smiled for a moment and then looked up into a pair of deep brown eyes that had always annoyed her, but today made her feel safe.

"Morning" Lexa told him, smiling. Brennan relaxed and leaned closer to kiss her.

"Morning" Brennan whispered against her lips.

"We don't have anything to do today; the people here give us a free day to be with our husbands or wives. I guess we could rest" Lexa explained.

Brennan laughed and rolled them over so she was beneath him and pressed against the bed.

"Rest is the last thing on my mind right now, last night wasn't enough for me" Brennan told her and then started to kiss her hard and deep, he sucked and bit her lips, deepening the kiss and making her moan. When he pulled away he was already in position, the last thing he said before he entered her was "Mine" and Lexa cried out "Yours".
