You Need to Relax

One Week Since The Bet

Planning ahead has never been Alex's forte. Her plans are never completely thought out, and generally thrown together with a moment's notice. Usually due to the fact she either wanted something, made a mistake, or because it sounded like fun at the time.

Alex also considered herself a simple person. Believing life's too short to not spend it doing what makes you happy. Which was what Alex was currently reminding herself while attempting to not think too hard about her current predicament.

However, recent events still played in her mind that she was actively trying to ignore. So far she considered herself successful. It had been a whole week since said events (not that she was keeping track of days). Also, it didn't help that he was ignoring her as well. In moments like this she would remind herself of The Steps.

Step one: act normal.

She was only partially succeeding at this task while Harper droned on and on about how she needed Alex's assistance with her birthday present to Zeke.

"I think this could be good for both of us, Alex!" Harper's positivity really chipped away at Alex's already low tolerance.

"You know what's also good?" Alex squinted softly and tilted her head. "Eating a full tub of ice cream by yourself in one sitting. There's such a thing as too much Harper."

"You already used that excuse last time. Didn't work then either," Harper scoffed. "Think of it this way. If you help me now, you won't have to spend time knitting or creating a new purse later."

"Ugh, Harper , do I have to?" Alex guided herself backwards into the cushions with a whine.

"Well, no, but I wish you would." The redhead walked towards her to sit on the orange sofa. "Please Alex. I really need your help. It's Zeke's birthday tomorrow, and I need help perfecting my dance routine I made for him."

Alex sighed, knowing there was no way out after seeing the pouting desperate expression upon her friend's face.

"Oh, fine! I'll help," Alex groaned. "But I would like it noted that I never wanted to be a part of cheer in the first place."

"Yay!" Harper clapped her hands before quickly attempting to give Alex a hug. "Thank you, thank you, thank you!"

"Mmm, let's make sure we're on the same page here, Harper. Okay?" Alex slipped sideways using her legs to help her escape. "You do know I was only in cheer because it was a requirement, right?"

"Yes, Alex. I do." Harper paused staring up as Alex crossed her arms. "It's not like I forced you to learn cheer though. It was that Franken-monster-thingy."

Alex scrunched her nose at the memory. "You're only partly correct. You didn't force me. Justin did."

"I guess that's true." Harper nodded and proceeded to smile. "Well one of the reasons I wanted to learn cheer was because I get to wear the skirt. Which all guys like, including Zeke."

Alex frowned her brow while looking over the redhead when a thought came to mind. All guys like … Hmm. Could that have been a motive?

A smile quickly replaced her pinched expression. If it was, then this thing had been going on for a lot longer than she thought. Now she had her reason to actually practice. All she had to do was convince Harper to practice in the living room.

Teasing him is not one of your steps, Alex. She shrugged off the thought.

"Look, since I'm helping and all, we should just do it here. Right next to my couch so I can take breaks." Alex bent down and grabbed her wand from her boot.

"Well, what if Zeke sees?" Harper asked and Alex could hear the hesitation in her friend's voice.

"It's not like he knows you're planning on dancing for him, does he?" Alex asked with a tick of her brow.

When Harper shook her head no, Alex smiled. She lifted her wand and casted the spell. " Transfix, Transpose, turn Harper and I's outfits into my idea of cheer clothes ."

A rush of light enveloped them briefly and Alex looked down to see her masterpiece. Her cheer outfit was purple and black. There was a perfect amount of dip making her cleavage look more pronounced while the cold air hit her exposed stomach. If only this had been their school uniforms, Alex might have liked wearing it.

Alex smiled before looking at her friend's outfit. Harper's was a sunshine yellow with white accents and not nearly as revealing. Still cute though.

"I thought we'd use the school ones, although this is pretty cute." Harper admired her new outfit.

"Eh, these are better," Alex said before pushing the coffee table out of their way. "Alright let's get to it." Alex set her wand on the table looking at the clock. They had one hour before Justin and Dad should be home.

Perfect. Alex smiled again and turned to her friend. New plan, see if this catches his attention.

Justin knew that if he was unsure how to navigate or execute a plan properly, the best thing to do was try a new plan. Unfortunately, every plan he came up with lately didn't have a desirable outcome. Because of this, every part of him told him not to do anything and to forget what happened. So he was doing just that. Pretending as if nothing happened.

The question was, what would be the desirable outcome?

"What'd I tell ya?" Justin started to climb the stairs tossing a look at his dad. "Best chili cheese hot dogs, in New York."

"You sure did." Justin laughed as his dad rubbed his stomach while reaching in his pocket. "Mint?"

Justin nodded, popping two in his mouth while his dad passed him to go upstairs.

"Next we'll have to try the best pizza. I know of one that's probably the best slice you will ever eat," His dad said and Justin trailed behind him towards the kitchen.

That's when he saw Alex.

His full attention turned towards her as he slowed his pace to a walk. Taking his time to study every inch of her exposed skin, he softly inhaled. In the moment, all he could think about was the memory of being close to her, almost as if he could recall the feeling of her skin under his fingers. Maybe it was the sway of her hips or how when she dipped forward her excessively short skirt would flip upwards.

The sight of her made his face extremely warm with his own heated thoughts. Watching her so closely, he felt his breath catch when she tossed a look over her left shoulder before smirking at him.

She's trying to kill me. He swallowed the thought.

Suddenly, without looking, Justin felt a sharp pain in his big toe after accidentally kicking the island.

"Fuck." Tearing his attention away from her, he hissed.

"Language, Justin," his dad scolded as Justin slipped his foot out of the sandal holding his toes. "You know so many other words you could use."

"Yeah dad, I know." He huffed and sat upon the stool beside him. "I'm setting a bad example, understood."

"I'm not sure if this has to do with Alex and her cursing, but you know how your mother and I feel about it." His dad continued to talk and Justin looked to his right.

Alex stepped towards the counter, and now that she was close he could see the flush of her cheeks and the rise of her chest from working out. The exposed stretch of skin on her stomach made him bite his own tongue.

I'm going to hell, he thought and swallowed thickly.

"Me? I didn't do anything this time." Justin listened to Alex's sharp tone while he looked at her doe like eyes.

If you're going to Hell, then I guess I'll be there to keep you company. Justin stiffened and looked down when he heard her voice in his head. Also, you have got to stop staring before dad sees you.

I wasn't staring, he thought back in a biting tone and glanced up to see a small twitch of her lips. Stop listening to my thoughts, Alex.

Right, okay, Justin. I'll get right on that. He huffed at her mocking response.

"Dad's right. We shouldn't curse." Justin looked at his dad before slipping his sandal back on. "It won't happen again."

Without looking at her he knew he needed to excuse himself. He made his way back down to the substation without another look or word.

That is NOT avoiding, he thought to himself as he descended the stairs. Which until there is a plan, avoiding is the plan.

He walked to the freezer and opened the door. Right now he wanted to be alone in the lair. It wasn't his fault. She was the one prancing around in - in that.

With a huff, he pulled out his wand twisting it between his fingers. He then proceeded to lie upon the couch with a sigh and closed his eyes. However, enjoying the quiet was short lived.

"What's your deal?" Justin opened his eyes to see Alex entering the lair with a bit of an edge to her tone.

"Me!?" He scoffed while using his arm to support his weight. "What about you?"

"What about me?" She scrunched her nose and crossed her arms. "I'm not the one cursing in front of dad or staring so obviously, Justin."

"Well take a look at you! Hmm, Alex." He sat up, throwing his legs off the couch as she came closer. "Look at what you're wearing. It doesn't cover or leave anything to the imagination."

Looking her up and down, Justin stood up. He stopped talking with an annoyed groan before turning away.

Abort! This is not part of ANY plan. He ignored his own thoughts.

"So what, Justin." He turned back towards her as she continued to cross her arms with a glare "You didn't see Harper or Dad act this way. I'm not going to dress like a nun or something just to make you comfortable."

"Yes, Alex. That's exactly what I was thinking." Justin rolled his eyes.

"How am I supposed to know what you're thinking?" He looked into her eyes only to see something he couldn't quite place. "All I can do is assume, because it's not like I've seen or talked to you in days."

"You're right," he sighed. They needed to make a plan. "We should talk."

"We don't need to 'talk,' Justin." He watched her put air quotes around the word "talk" as she rolled her eyes. "You just need to relax, and we'll be fine."

He gaped at her and repeated her suggestion. "Relax?"

"Exactly." She smiled before reaching out and patting his cheek twice.

"No, Alex. This is serious." His tone was quiet but stern. " We had sex . That's not a topic you just move past and don't discuss."

Justin looked over her features trying to see how she would react as he continued. "Relaxing isn't the answer. We need to finish having a conversation about what we are going to do."

She huffed and moved past him to sit on the couch. "That statement just screams: 'I need to relax'. "

Justin followed suit with a sigh. "You need to stop deflecting and tell the truth. Which I know may be difficult for you."

When he looked to his right he saw her scrunched expression which meant her patience was wearing thin. That was when he watched her adjust herself and get on her knees beside him. Before he could react, she leaned closer and gave him a push so that he was now on his back.

"Alex, what are you-" he started to talk but froze when she straddled him mid thigh.

"Like I said, Justin. You have got to relax," she huffed, leaning forward to grab something above him on the side table.

Trying to see what was in her hands, he gasped as she shoved his t-shirt up as far as she could. He shivered at the abrupt chill from the lair. Sucking in a deep breath, he felt the tightness starting to develop in his abdomen while her fingers lightly traced the dips in muscle. Looking up at the ceiling he sighed into her touch.

The feeling in his gut doubled when he felt her warm breath upon his skin. Her lips trailed slowly up, starting at his navel and pausing between his pecs. Just when he was about to look at her, he inhaled sharply feeling her lips and tongue against his left nipple.

"Gah, Alex." He managed to get out her name before feeling her teeth grazing his skin.

Then he felt her administrations stop and he closed his eyes hoping to level out his breathing. That was until he felt something on his ribs being dragged against his skin. Almost as if she were drawing something. His eyes snapped open and he looked down only to see her finish the singular word.

Relax.

"Alex!" Justin only had seconds as he looked at her. Then a warmth washed over him as if all the tension left his body at once leaving him suddenly less concerned.

"Justin?" He looked at Alex who held the magic marker in her hand. "How do you feel?"

"Uhm, like a huge weight has been lifted," he sighed and felt himself smile a little. "Logically, I want to tell you to erase it since I can't do it myself. But it feels nice to not have that weight."

"See. My plans don't always fail." She laughed. "My work here's done."

Justin studied her as she put the cap back on the maker while sporting a rather accomplished smile. Shaking his head, he decided that this was his opportunity to take control of the situation. He started by quickly reaching behind her placing his hand on the small of her back. In one swift motion, he'd managed to guide her backwards and onto the couch now beneath him.

"Justin?" She swallowed and he could see the confusion on her features.

He ripped the marker out of her hand. The surprise startled her for him to lean his face close enough to brush his lips on her left cheek. Ghosting them across her lips, he basked in her shaky warm breath. Now that weight was gone, he wanted to burn every detail he shouldn't know about her into his mind. Every secret freckle, every small unknown scar, every breathy moan she makes and every spot on her body that only he should know about.

It was her that closed the gap between them. Pushing her warm soft lips against his own. Justin took his opportunity to deepen their kiss while drinking in her soft moan. Oh how he wanted to keep kissing her, but he needed to ask her one question.

"What did you mean?" He paused feeling her own uneven breath against his right cheek.

"What?" She whispered as he pulled back to see her searching his eyes.

"When you said it wasn't about the sex. What did you mean?" He clarified, drinking in her liquid chocolate gaze.

"I don't…" She started, but he shook his head.

"If I so badly needed to relax, then Alex you need to be honest." He huffed using his free arm to lift himself above her.

Justin's eyes scoured her body. His fingers dragged themselves down her stomach and he enjoyed watching the way her muscles twitched underneath him. He then paused at her thighs before pushing her skirt up a little revealing her matching black and purple panties. Tossing the cap to the marker on the ground, he started to write.

"Justin, what are you doing?" She attempted to wiggle away, but he used his free hand to stop her.

Pulling away he admired his word choice with a smile. His thumb tracing over the lettering.

"Be honest." He read the words out loud for her to hear.

He looked back up at her and watched her eyes widen. Just when she was about to say something he watched a light surrounding her momentarily. The marker's magic at work.

"What did you do, Justin?" She hissed, pushing him backwards and sliding away from him. Pulling up the skirt she looked at the words upon her skin.

"It's only fair, Alex. I mean, it's not like you would tell me what you were thinking otherwise." He moved so that he was sitting beside her.

"That's just great." She huffed with a glare. "What? You don't think I'm telling you the truth? You think I'm lying when I say we don't need to talk."

"Not lying, per se. More like evading questions. Which is typical." He nodded and pursed his lips. "I also wanted to hear why you said it wasn't about the sex for you either."

"Oh really?" She scoffed, "You really want to hear that it's because I am not only in love with you but also attracted to you?"

It was his eyes that widened first at her announcement and then he watched her cheeks burn pink. She opened her mouth and shook her head without saying anything. He smiled widely at her which was probably the reason she proceeded to smack him on his upper arm.

"Remove it. Are you happy now? Because you got what you wanted," she growled, and he shook his head.

"No, I don't think I will." He hummed with a smile while picking up the cap to the marker off the ground. "And yes, yes I am."

Justin set the marker down before using his right hand to guide Alex's face towards his own. Catching her lips with his own, he smiled into the kiss. At first, he could feel her hesitation knowing she was annoyed. This small victory sure felt good though.

"What...are we...doing, Justin?" She whispered between each short brush of their lips while he pulled her into his lap.

"Being in the moment," he responded and pulled away. "You're the one always saying we should choose to live in the moment."

Looking over her face, he used his fingers to brush away loose strands of hair behind her ear. He then smiled at her.

"I know you, Justin," she sighed. "Internally, you're probably freaking out right now because we shouldn't be doing any of this. We should erase the marker."

"Wait," he said, not wanting the fear and anxiety to come rushing back just yet.

He reached out, placing his hand upon her cheek. Looking in her eyes, he breathed deeply.

"Normally, I would be, yes." Justin paused, to brush his thumb upon her skin. " But - and this is probably the spell talking, I want you to meet me here tonight. We can remove it then."

Justin kissed her again to stifle any protests. All he wanted was to be with her like this, even if it was only for a little longer.

"Fine, tonight." She breathed into the kiss before pulling away and shaking her head. "Spell aside, I'm impressed that it's you convincing me to do something wrong."

He laughed and she smiled before standing up to walk towards the lair entrance.

"Like I said; logically, I want to erase it right now. So really, I'm just as impressed as you are." He stood up to follow her but stopped. "Hey, Alex."

Justin watched her turn towards him with the same smile. He melted under her gaze while looking at her. "I love you too."

The way her smile widened after hearing him say those three words made his heart beat a little faster.

"It seems we should have bets more often, huh Justin?" She lifted her right brow and left before he could answer.

He agreed with her. Under the warmth of the spell, he knew he should feel sick and disgusted with himself. What they were doing was wrong. She was his sister. Normally that word alone would bring a whole wave of panic, but all he felt was confused.

It was like she said, if it was wrong then why'd it feel so good to touch her and kiss her. Why did he feel the way he did?

Justin sighed, rubbing his face. If this was all because of the no magic bet …

He knew it wasn't. The bet was the catalyst, however the feelings were his own. It was something he had felt before, and he wasn't sure when it changed.

Just tonight and then we can figure out what to do, Justin thought before walking to the door.

One thing was for sure, he wasn't going to hold back.

Alex has never been good at waiting for anything. At times, she can be a creature of instant self-gratification. In her past, people told her that anticipation helps heighten the feeling when what you waited for happens. To this day, she thinks those people are still full of it. Mostly because when she gets what she wants instantly, there's nothing like it.

Making it hard to believe that waiting makes it " better ."

Unfortunately for Alex though, it had been four hours of waiting so far and the sun had only recently set.

What did Justin mean? Were they going to have sex- excuse her, "make love " tonight?

Would it be hushed or would they cast a spell? Would it be slow, sweaty, drawn out into multiple toe-curling orgasms that made her lips buzz? Would it be rough involving her nails on his skin as he trails soft loving bite marks all along her body?

All these thoughts made her head swim, and her heart thud faster. As previously noted, she hates waiting.

"Alright. I'm off to Zeke's." Harper smiled walking towards the door. "You sure he'll like the early birthday cheer routine?"

Alex nodded, adjusting her loose t-shirt while pulling the front door open.

"Harper, he's going to love it." She smiled at the redhead. "Now go, or else I'm coming with."

"Nope. Alex, we've talked about meddling." She shook her head and stepped outside. "Remember what happened last time?"

Alex nodded. "You have a point."

Then with a wave, her friend was gone. Looking at the clock, she sighed. It was only nine and she could still hear her parents awake upstairs. Going to the kitchen, Alex proceeded to get a cup of ice water and take a drink.

If you're already waiting, you might as well wait where he told you to. Alex tapped her nails on the glass of her cup.

With a smirk she made her way downstairs into the dimly lit substation. Looking around the quiet shop, she sighed and opened the freezer. There was a twisted feeling in her gut that made her pause as she shut the door behind her.

Justin's logic was correct. They shouldn't be doing whatever it was they were about to do. Even she knew this. However, the buzzing warmth she felt inside when he held her only validated both of their actions even more.

Setting her water down on the side table beside the couch, Alex walked over towards the bookshelves. Sitting wasn't an option right now. She was restless and needed to not talk herself out of what she wanted. Then the door opened softly.

Alex refused to see who it was, but knew when the door shut with a soft click it was him. The air around her felt heavy, as if no matter how many gulps she swallowed, it wasn't enough. Pretending to look at the books in front of her she listened to the soft padding of his feet against the stone floor.

Alex closed her eyes and waited. Maybe in this moment those people she said were full of it, were onto something. She could feel the thud of her heart in her ears. Shivering when the cold behind her shifted into a familiar warmth, his warmth.

A hand touched her hair, gently moving it away from the left side of her neck. Then another hand grazed her bare thigh before gliding against her skin towards her hip. The anticipation was killing her, but she revealed in it.

"This isn't a good idea." It was the first words he had said to her and they made her lean into his touches.

"No, probably not." She hummed as he pulled her oversized shirt off her left shoulder. He then brushed her skin with a faint kiss while digging his fingers into her hip.

"If you're looking for me to object, I'm not going to," she whispered, her voice was breathy, but had a bite in her tone.

"You really are going to be the death of me." He mumbled against her skin before leaving a trail of almost kisses to her neck.

She reached her right hand up to steady herself by grabbing the shelf. He proceeded to nip ever so lightly at her skin while she momentarily bit down upon her bottom lip. Alex then moaned when he attempted to sooth each bite with a kiss. Boy did the feeling of his lips on her skin make her feel weak in the knees.

His actions picked up and she felt him bite down a little harder than the other previous times. This caused her to inhale sharply with a moan before moving her hand off the shelf, behind her, and into his hair. With a good tug, she listened to his groan and smiled. The second she released her hold on his hair, he abruptly spun her around before pushing her into the books with a soft thud.

"Sorry…" He whispered against her lips and she shook her head looking up at him through half lidded eyes.

"You would apologize for that," She scoffed.

Alex took this as her opportunity to put both hands on his shoulders. Justin seemed to understand the idea as he reached under the swell of her ass to lift her into his arms. Wrapping her legs around his waist she tossed her hair to one side as she looked into his eyes.

With her back leaning against the shelf, he reached up with one hand to trace the side of her face.

"God, you're so beautiful," he sighed.

Alex couldn't help tangle her fingers into his hair before leaning in to capture his lips. Taking advantage of the new angle, she deepened the kiss causing him to groan. Without opening her eyes, she felt him push off of the bookshelf and start to walk. Sucking his lip between hers, she bit down roughly. This caused him to gasp digging his fingers into her ass. Smirking into the kiss, she felt him guiding her backwards onto her back. Breaking apart for air, Alex pushed her hair off her face as they adjusted on the couch.

"Maybe we should talk beforehand," he said between short uneven breaths, and Alex felt her left brow tick upward.

"God, Justin. Even when relaxed, you're still trying to be rational," she huffed, placing her hands upon his chest.

At this moment, all she wanted was for him to ravish her. Without lifting her hands she trailed her way down, past his abdomen only to pause at the apparent bulge in his pants. Looking into his eyes, she waited allowing her fingers to dance before abruptly cupping him outside his sweats with her hand.

His expression pinched, with a loud groan followed by a: "Fuck, Alex."

Pleased with his reaction, she smirked and loosened her hold upon him. Quickly taking the hint, she helped him push his shirt up before he tossed it behind him. Alex took the opportunity to study each dip in his muscle with her fingertips.

He really is attractive, Alex thought to herself.

Then she found herself looking into his eyes, darker than his usual stormy pool. She could see her own desire reflecting in his features. With a sudden brush of movement, she watched him push her t-shirt up. Using both hands, she discarded her shirt and sighed. The cool air hit differently against her now fully exposed chest. She watched his eyes, still hungry with want, taking every inch of her in.

Justin hesitated, before trailing his fingers across her abdomen. Alex gasped as his knuckles brushed against the underside of her breast. She watched him lean his head down before he proceeded to take her hardened nipple into his mouth. Suckling and lapping.

With a small arch of her back and a whimper, Alex felt his hand resting under her opposing breast.

"I need…" She accidentally found herself starting to talk as he paused his administrations.

"Tell me what you need, Alex," he coaxed against her skin.

Everything smelled of Justin. Her whole body thrummed in excitement while she tightened her legs around him.

She stood corrected from before. Those people were still full of it. Waiting was overrated.

Reaching down she guided his head upwards to look him in the eyes. "What I need is you, Justin." She breathed, lifting her hips so that she could feel him against her.

The abrupt rise and fall of his Adam's apple followed by his groan made her shiver. Her words were their breaking point of anticipation. They both began to pull away at her shorts followed by her panties. Reaching for the band of his sweats, she helped him discard them before feeling the heat of his skin flush against her own. They had all night for sweet and gentle. Right now she wanted to just feel him. Every rough movement and abrupt race for pleasure made her skin tingle.

Without another word, she felt him between her legs, guiding himself against her slick heat. Alex lifted her hips towards him and he finally took the hint as he positioned himself at her entrance. Pushing inside, Alex moaned loudly pulling him closer before digging her nails into his back.

His movements mirrored her own as he dipped his head into her neck. Growling against her skin he pulled his hips back slightly before pushing back in. Every thrust added to the delicious and familiar heat they both sought. She felt it building in her lower half as he bit down on her collarbone roughly. Alex responded with a gasp before dragging her nails down his back.

There was a fervor in his hurried movements as he quickened his pace. Skin sliding together as the couch squeaked.

"Justin ..." Alex's voice trembled when he reached between them with his right hand.

In uneven breaths, Alex opened her eyes feeling their bodies rocking together. Looking at his pale shoulder, dipping forward against her rhythmically while she turned her gaze to the side of his neck. With her right hand, she guided her fingers against his skin and into his hair.

"I love you." She felt the blossoming warmth and the fluttering of pleasure build. "Justin …"

"Alex-." She listened to his voice before turning her head to capture his lips. Their bliss reached its peak with one last rough thrust.

Justin's movements then started to slow while Alex relaxed in echoing pleasure. Taking in the buzz in her lips and throughout her body, Alex relaxed. They took those few moments to catch their breath before he pulled out.

With a sigh, he rolled to the inside of the couch. This moment was everything she wanted. Feeling him wrap his arms around her, she closed her eyes with a smile.

"I love you too," he whispered in her ear, kissing her temple.

Alex sighed, looking down at her thigh. The words were smudged and faded.

"I wish things were different," she spoke softly. "That we could be together."

"Me too." She felt his words brush against her skin while a single tear slipped down her cheek.

He is worth the wait, Alex thought before welcoming sleep.
