Okay just so everyone knows to start this story off, Alex and Justin are step-siblings. They have no blood relation and their parents married when Justin and Alex were kids. They've always been close but lately things have changed. There's no real plot to this....it's mostly just smut....let me know if you think I should make it into a chapters story. If I get enough reviews, I just might.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

"Mmmm Justin," Alex moaned as Justin continued to trail kisses along her jawline and down her neck. Her hands were barried in his dark hair pulling him further into her. They were laying on his bed and they were involved in a pretty heavy makeout session. "Alex.." Justin said as his hands snuck under her shirt and he lavished her sides with featherlight carresses. Alex began to moan louder as Justin's hands got closer to her breasts. "Alex...." "Alex..." "ALEX!!!!!"

Alex woke with a start to the sound of her moms voice. "It's time to get up honey, you're going to be late for school." "Okay mom, I'm up!" she shouted sounding a little more then angry. "Can't believe she woke me up at the best part.." 'Well maybe not the best part but one of the better ones.' She thought with a threw her covers off and started humming to herself as she made her way to the bathroom to take her morning shower.

*Alex had been having dreams about her step brother for the last six months. At first it had freaked her out, she thought she was disgusting. She couldn't believe that she would have such thoughts about her own brother. They started out innocent at first, little glances at his mouth when he was talking, blushing when he would compliment her, her heart racing whenever he was around. But then he became more then that.*

*She had seen working out one night when he left the door to his room open. He was doing push ups and lifting a few weights. She had no idea he even worked out. She had always thought of him as such a geek. But she would never look at him the same again after that night. Seeing his ripped abs and his muscular arms. She felt herself getting wet just watching him, fantasizing about his sweaty body all over her, his arms around her. She had gone straight to her room and masterbated. She had never come so hard in her life. She new after that there was no going back.*

Alex was making her way to the bathroom when she heard a strange noise coming from Justin's room. At first she ignored it, she was about to open the bathroom door when she heard it again. Her curiosity got the best of her and she tiptoed towards his room. "Alex..." She heard him say her name.

She put her ear to the door and listened closer. "Alex...mmmm...Alex" Her eyes widened, 'Did he just-' She found herself opening the door. As she peered inside it was still dark but she could make out his figure laying there in the bed. She stared at his bare chest that was slightly illuminated by his nightlight. Alex snickered to herself, 'I can't believe he still sleeps with a nightlight.'

He appeared to still be sleeping. So she continued to walk closer, "Alex.." "Justin?" she whispered. Thinking he was awake she walked over to him then. Seeing that his eyes were still closed she realized he was still asleep. 'Hmm that's weird he must be dreaming about me. Ha! He's probly dreamin about yelling at me for replacing his toothpaste with preparation h.' Alex snickered to herself again.

She was just about to turn around and leave when, "Oh God Alex, D-Don't stop...." followed by a low moan. 'Okay that definately wasn't him yelling at me....' she thought to herself as she turned and walked back to his bedside. It was then that she noticed the "tent" in the bed. "Oh my God" she whispered and covered her mouth. 'He's having a sex dream about me!!!' She screamed at herself.

"Feels so good..." Justin mumbled once more in his sleep. Alex couldn't help the pure feminine smile that came over her face. She had an idea, she just hoped it worked. She knew that Justin slept very soundly, sometimes you could be right in his face yelling at him and he wouldn't wake up, sometimes she would shake him for ten minutes trying to wake him and he would just roll over. And that gave her an idea.

Alex slowly peeled back the covers to reveal Justin's naked body. Alex gasped, 'I had no idea he slept naked. And oh my God would you look at his cock? Mmm it's better then I pictured it. ' She thought to herself happily.

She placed one knee on the bed keeping her eyes on Justin's the whole time. Eventually she was straddling his ankles, (yes his ankles), which brought her face to face with his cock. 'Oh my God, I can't believe I'm going to do this.' Was the last thing she thought as she gently grabbed his member with one hand while using the other to steady herself on the bed as she bent down and gently licked the tip.

Justin's hips rose up off the mattress as she did so, and her eyes shot to his face once more to make sure he was still sleeping. Once she was satisfied that she hadn't woken him she slowly began to take in more of his cock. "OH GOD!" she heard him say in a hushed tone. "That feels so good baby...."

Alex smiled around his cock and gave it an experimental suck. "Mmmm" Justin moaned in response. She slowly started to work her hand up and down while lightly sucking on his cock. She found herself moaning as well, she couldn't beleive how much this was turning her on. She could feel that her panties were completely soaked through.

She snaked her hand past her pajama pants and into her panties and began to play with her clit. "Mmmm" she moaned around his cock. It was almost too much for her, having Justin's rock hard cock in her mouth and touching herself. She was gonna come soon for sure. She stopped the ministrations on herself and started to focus more fully on Justin.

Justin's hips soon began to raise in time and rhythm with her hand and mouth. She was so caught up in everything she didn't even realize that Justin had opened his eyes and was now awake.

"Oh God Alex, please don't stop....mmmm...f-feels so good. Oh yeah....just like that..."
Alex smiled around his cock. She was so happy that she could make him feel good, she had never done this before, to anyone. "God Alex I wanna fuck you so bad" she heard him say and this caused her to look up at him once more.

Looking away as quickly as she had looked at him and then looking up once more realizing that infact he was awake now she stopped what she was doing and almost fell off the bed. "Justin- I can explain, oh my God-" she started but was cut off when Justin's mouth pressed to hers.

She found herself falling into his kiss. She felt his tongue teasing the bottom of her lip, begging for entrance, which she granted willingly followed by a moan from him and sigh from her. Justin quickly pulled her into his lap as he cradled her face and then began kissing along her jawline and down her neck when breathing became an issue.

"Mmmm Justin," she moaned, just like in her dream. "Alex...I want you so bad..." She heard him say and she felt a gush of fluid flow to her pussy. She gently pushed him away, at his quizzical look she gave him a flirty smile and pulled her pajama shirt over her head and then stood to remove her pants as well.

"God you're gorgeous," he told her making her blush as she stood there before him in nothing but her panties. He pulled her back down to the bed and crawled ontop of her, placing his naked body between her legs. She moaned when she felt his hard cock touch her nearly naked pussy.

She pulled Justin's face to hers and began kissing him passionately grinding her soaking wet panties onto his hard member. "Mmmm I need you Justin..." she said as he began kissing down her neck again, making his way to her breasts. Soon he began kissing and squeezing them. This only drove Alex more crazy. "Justin please, I need you in me, NOW!!" she cried.

Justin smiled up at her and continued his decent. He gently removed her panties and began kissing up her thighs on his way to her sex. All the time rolling her nipples between his fingers. "Oh God Justin, PLEASE!!" she cried again. And then his mouth was on her and Alex couldn't think straight. She had never felt anything this good in her whole life.

Justin slowly worked his tongue along her slit and then began gently sucking on her clit. He brought one of his hands to her hole and slowly worked his finger in. "Ooooo O-Oh Oh m-mmm" Alex couldn't even form words. The things that he was doing to her with his hands and his mouth. "Justin...." she moaned as she thrashed her head back and forth on the pillow. "J-Justi-nn I think I'm gon...na..." Justin looked up at her as he curled the now two fingers that were inside her just right, "Come for me Alex" he whispered to her as he sucked her clit hard one last time.

Alex grabbed a pillow and covered her face just before her whole body began to shake and she screamed into the pillow having the most intense orgasm of her young life. She could swear she blacked out for a minute. But she can't be sure, all she knows is she can feel Justin slowly kissing up her body again and the pillow is being pulled off her face and she sees his big beautiful eyes staring down at her.

"You're amazing," he tells her and lightly kisses her lips. Alex gapes at him, "Me? You think I'm amazing, that was....I don't even have words for that....I'm exhausted and I didn't even do anything." she says looking up at the ceiling with a huge smile plastered on her face. Then she sees Justin pouting, "So does that mean you're not up for more fun?" he asks looking so cute she can hardly stand it.

Alex laughs, "Are you kidding me? After seeing your cock and feeling it pressed against me, how could you think I wouldn't want you inside me as soon as possible?!" Justin smiles and starts playing with her clit again as he kisses her neck. "Mmmm God would you just get inside me already?" Alex cried, "You're driving me crazy!!" "Now you know how I've felt for the last two years." Justin tells her.

"Two years?" You've wanted me for two years?" "I can't remember how long I've wanted you for, I just know that's when the dreams started." he tells her slowly climbing ontop of her and capturing her mouth in a searing kiss. "Wow" is all she can say.

Justin starts to climb over her a little and reach for something. Alex grabs onto him tightly, "Where are you going?" She asks feeling insecure and she doesn't know why. "Condom" is all he says and returns to his place between her legs once more.

"Oh" she says feeling a little silly. Taking the condom from him, "Here let me do that for you" she rips it open and slow places the condom onto his hard cock. It seems even harder then before if that's possible.

Alex rolls him over so she's ontop. "Have you ever...." "Ya a couple of times with my ex," Justin tells her, "Have you ever..." "Once, with this guy, he was working for my-" "I don't wanna know" he says with a chuckle. Alex laughs a little laugh as well, "Right, sorry."

She roughly pushes him back on the bed and uses her hands to raise herself up. She positions herself over his cock and looks into his eyes, "Ready?" she asks him and he nods. She slowly slides down his member and they both moan. Her at the feeling of being filled more completely then she ever has and him and the feel of how warm and tight her pussy feels.

Alex leans her forehead against his and they just lay there for a moment. "Oh God you just feel so good" she says with her eyes closed. Justin's answer is to pull her into a passionately slow kiss. When they finally break apart Alex begins to ride him slowly at first. "Alex..." He reaches his hands up and plays with her breasts as she starts to ride him faster. "Oh God....yes...." She moans.

Justin flips them over so that he's ontop. Alex looks at him questioningly. "You were going too slow...mom will be up to check on us soon. We'll have to save slow for next time." he tells her with a smile and starts to move faster.

"Oh God Justin...mmmm...ah.....harder.....o-oh yessssss......harder.." she says grabbing onto his ass and pulling him into her further. "Oh god Alex" he says as he pumps into her harder and faster. "Oh God you feel so good, you're pussy is so tight and warm." he tells her closing his eyes and biting his lip. Alex doesn't think she ever been so turned on in her life as she sees him do this.

Soon she has no thoughts at all and she closes her eyes and just gives in to what her body is feeling. All she can feel is him, all she can smell is him, all she can hear is him, she completely surrounded by him and she loves it.

She feels her climax coming on, "Oh...Justin I'm gonna come...o-oh mmmm yea.....yes yes yes......OH GOD!!! JUSTIN!!!!!!" Justin thrusts harder and harder, he can feel it too, he's on the brink he just needs something to send him over the edge. He looks down and sees Alex looking at him wide eyed and then her eyes snap shut and she moans and he feels her pussy clench around him and then he hears the one thing that send him over the edge. "O-oooh I love you Justin!!" And then they're both over the edge and he hears a voice that sounds a lot like his say " I love you too Alex."

Okay, the end! I hope you guys like it. This was my first lemon and I just recently got really into Justin and Alex.
