Rated M for Mature - Warning Sex scene

Sebastian pushes her into the wall. His whole body is pressed up against her and he smashes his lips against hers. Clary gasps, shocked at first but then her mouth starts to react to his lips. Their lips move hard against each other. She lets his tongue explore her mouth and it swirls around her own tongue and then he bites her lip causing her to moan. He breaks the kiss and starts to nibble on her ear, making her shiver.

"I want you." Clary says to him.

Sebastian smashes his lips into hers again but this time, it is with more hunger and desperation. "You have…no idea….how many times….. I've dreamed of you….. saying those exact words to me." he says between kisses. He pushes his body harder into her, grinding into her hips, causing them both to moan. They kiss for what seems like hours but only minutes had passed. Sebastian breaks the kiss and moves to her neck where he starts to suck and nibble on it, causing her to moan again. Sebastian growls and grinds his hips harder into her, making Clary moan even more. She can feel herself getting wetter by the second. She can't think straight anymore. In the back of her mind she knows it's wrong to love this and to want him, but a bigger voice is saying "Who cares? He feels so good and he's so fucking hot."

Clary starts to grind herself on his erection she now feels in his pants and he moans and claims her lips again. She wraps both of her legs around his waist and Sebastian puts both of his hands on her butt to support her while he carries her to his room and lays her on his bed. Clary pulls his shirt over his head and then looks at his hard pale chest and runs her hands down his hard abs. She has been wanting to do that for too long.

She bites her bottom lip and looks up at him. Her green eyes meet his black ones that somehow look like they have gotten even blacker with lust. He rips open the front her dress to reveal her black lace bra and then pulls the rest of her dress off of her body and throws it across the room. He looks at her while she is only wearing her lacy bra and black lace thong and he growls in appreciation. He then rips his pants off and throws them across the room leaving him in only his black boxer briefs. Sebastian jumps on top of her and places himself in between her legs. He bends down and starts to trail kisses from her stomach all the way up to her neck and jaw and then finally her lips. One of his arms is propped on the bed so he won't crush her while the other free hand is roaming her body, feeling every part of her as he grinds his erection into her. His hands start to unclip her bra and Clary stiffens, making Sebastian break the kiss to meet her eyes.

"What's wrong?" he asks looking worried.

"It's just...I've never...you know." she says looking down and trying to hide her face in her hair. Sebastian takes his hand and puts it under her chin and lifts up her face so their eyes meet.

"We don't have to do anything if you don't want to." he says brushing his thumb lightly against her cheek.

"But I want to. I want you." Clary says in a seductive voice." I'm just afraid. I don't know what to do. What if I'm not good? I know you've been with a lot of girls."

Sebastian puts his finger on her mouth to get her to stop talking. "Clary, I love that I'm going to be your first and that nobody but me has ever touched you...or will ever get the chance to touch you. I will teach you everything. You could never not be good at sex. I have a feeling you will be amazing at it like you are at everything else. And yes, I have been with many girls, but none of them ever meant anything to me. Like I said before, it was only sex. But when we make love, it will be my first time making love. It will not be just sex for me. It will be our bodies, our hearts, and our souls becoming one. Making our bodies as close as possible." Sebastian says this in a husky sexy voice that makes Clary grab him and start to kiss him.

He then goes to undo her bra again and this time, she doesn't stop him. He pulls it off and breaks the kiss and looks down at her perky breasts. "You're the most beautiful creature I've ever had the pleasure of laying eyes on." Sebastian says as he starts sucking on one her pink nipples, causing her to moan and arch her back while his other hand starts playing with her other breast. He trails kisses down her stomach and to her thighs. He kisses up the length of them till he gets to her thong. He then looks up at her and his face is so close to her pussy, she can feel his hot breath on it. Their eyes lock and then he pulls her thong down with his teeth and throws it off of his bed. His lips move back up her thighs until he gets to her pussy where he slowly licks her folds, causing her to moan. He starts to lick and suck her clit while she arches her back up and moans. Her hands move down and grab his hair where she pulls it a little.

"Ohh…Yeahhh…That feelllss soooo…goood" she moans.

He then pushes one finger inside of her and thrusts it in and out, causing her to moan even louder. He then adds another finger and thrusts it in and out, making her jump a little and cry out in pleasure. He eats her out for a while until she is almost ready to cum and then stops suddenly and starts to kiss up her body. His kisses get higher and higher until their lips meet and she tastes herself in his mouth. She takes her hands and reaches to his boxers to try to pull them down. He breaks the kiss and sits up and takes them off quicker than she thought was possible and it makes his cock spring free when he pulls them past it. He throws his boxers away and Clary bites her lip as she stares down at his large hard cock. He crawls back on the bed and on top of her. Sebastian spreads her legs and takes the head of his cock and rubs it between her legs, making her moan loud with desire.

"Okay. This is going to hurt. I promise I will be gentle...well only the first time so you can get used to my cock inside of you." Sebastian says in a husky sexy voice. He then slowly enters her until he is all the way inside of her and stays still until she gets used to it. She has tears going down her cheeks while her eyes are closed. He starts to slowly move in and out of her until she starts to moan. He then picks up speed, making her moan louder.

"You're so fucking tight. You feel so amazing on my cock." he says in her ear as he nibbles on it. He starts to thrust harder while grunting and growling like an animal. Clary is moaning so incredibly loud while she claws his back and he moans in response.

"OH! I'm going to cum!" Clary screams as Sebastian starts to roll his hips hard in a circling motion. He can feel her walls start to clamp on him as she cums; her legs shaking uncontrollably. "Ohhh goddd ,Sebastian." she moans out, making Sebastian's breathing harder and making him grunt.

"Clary!" Sebastian moans her name as he cums inside of her.

He collapses on top of her and they stay like that until they catch their breath and their heart rates go back down to a normal rhythm. Sebastian moves to lay next to her and then pulls her to him and covers them both with his black silk sheets. He kisses her head as she starts to feel sleep coming over her. Just before she is taken by the darkness, she hears Sebastian whisper, "You belong to me now, sister mine."
