A/N: Forgive my late update. Took a while to get this exactly right and because I also decided to expand on it. The plan is this is the last for Cass and Eric. But it leaves off with a to be continued for Four and the plan is to then lead into a to be continued with Four and Tris. So for my Fourtris lovers out there...something is coming up for you too. Hope you enjoy this hopefully will wrap things up nicely for Cass and Eric and show just how and why they have such depth and chemistry. And why the crazy kids waited so damn long. ;)

Part 4

Sound inspiration: Boy Epic 'Tell me you love me' 'Scars', Skylar Grey 'Kill for you', Halestorm 'I'm not an angel' 'I Get Off', Ella Eyre "We don't have to take our clothes off'

"So you are meeting your brother for drinks or something before you are supposed to meet up with Eric?" Victoria asked from her closet as she was getting changed.

Cass had come to her apartment to get changed and ready instead of going to her own apartment. She knew that it was better not to chance running into each other or the temptation that being right across the hall from each other would bring.

"Yeah that is the plan." She replied to Victoria and couldn't help the laugh in her voice at the thought of her plans for her brother. While she did intend to mess with him she had no intentions of causing him lasting harm. He would never know his sudden lowering of inhibitions was because of her but it was the only way for her to crack through that abnegation shell he insisted he wear.

"Why does it sound like you are up to something Cass?" Victoria asked with a laugh as she brought out the knee high black boots that Cass had asked to borrow.

Cass shrugged and turned as she looked at herself in the floor length mirror. She smirked when Victoria handed her the boots. "Probably because I am. No I will not tell you until I know it even worked. But I promise you will be the first to know."

Victoria laughed and nodded. "I can deal with that. Now let's take a look and see if your outfit needs anything else?"

Cass had chosen to go with a dress since she had already teased Eric with her going sans underwear. She wasn't wearing any kind of underthings tonight. Her dress was a strapless black skater dress that had a sweetheart neckline. The dress had a built in bra so she had decided not to worry about one. The top of the dress was tight until it got to her waist and then it flared out into a pleated skirt that went to above her knee by a few inches. She had chosen to wear the boots for extra coverage of skin and to let a little bit play peek a boo.

The dress itself was plain but well made and she had paired it with a simple silver metal belt that is about the width of her hand. She chose the dress because she was showcasing something in particular.

Cass tilted her head and then sat to put on the boots to take in all of the outfit. She smiled when she stood back up and Victoria nodded.

"Perfect. With you hair pulled back on the sides it is exactly what you were going for."

Cass nodded and chewed her lip a little nervously. Tonight would be the night they would allow themselves to finally come together. One year he had said and they had waited that damn year but not a moment sooner.

Victoria smirked at the young woman and patted her shoulder. "Do I sense that something big might finally be happening for you two?"

Cass looked to her friend and blushed a little. "He said a year and it has been a year. Though I have to admit it has felt like centuries at times."

Victoria shook her head and laughed as the two walked to the living room to grab the small clutch purses with their phones, credits cards and other items they might need. "I don't know how you two did it. I don't understand much of why you did it either but that doesn't matter."

Cass sighs as they leave her apartment and walk to the bar that all the leaders and senior members prefer and reserve for nights like tonight when there is a big celebration going on. "It was important to him Victoria. It was important to me too but more him."

Victoria nodded with a smile as they walked. She always found it amusing that Cass could draw the eye but there was always someone there to remind whoever was looking who exactly she was and who she was with.

The faces paling before they averted their eyes quickly was enough to have the women laughing as they entered the bar. Victoria split off from her and went to the table that a few of the other leaders and members were gathered around.

Cass went to the bar to wait for her brother who would be arriving any minute to meet with her. She shared a wink with the bartender Liliana who looked at her and winked back to let her know everything was set.

It didn't take long before Four was sliding into a stool beside her, looking her over with a slight frown marring his features.

"Cass." He tried to wipe the frown from his face and smiled at his sister. As much as he hated her choice of men and the fact that she went with leadership knowing it would put her in contact with their father, he was proud of her and all she had done for Dauntless and herself.

He had been surprised she had invited him for a drink but he hoped it could be an opportunity to talk some sense into her about her and Eric.

"Four." Cass smiled at him and rolled her eyes internally when she already saw him mentally preparing the 'walk away from the dark side' speech he was poised to give. She needed to get those drinks in him now before he could piss her off and make her deck him or say fuck it and walk away. "Before you start brother dear, just have a damn drink with me and celebrate for fucks sake."

She motioned to Liliana who placed two glasses of scotch in front of them. Cass picked up her glass and held it up for a toast, giving Four no opportunity to hesitate or turn it down. He picked his own up and held it waiting for her to make one first.

"To another year away from that fuck that called himself our father. To another year in the only home we always knew we belonged. Finally to my first year as being a full fledged leader." She smiled the last part, truly proud and happy that she had accomplished what she had set out to do before she ever came to Dauntless and in a short time as well.

Four gave her a sideways smile and nodded. He decided to let her have this night before he broached the topic of Eric…..again. So he clinked his glass with hers and drank his down along with her.

"So what have you been up to Four?" Cass said after they had both drank a good portion of their drinks. She was already running a mental stop watch on how long everything would take to hit his bloodstream.

As Four launched into what he had been up to and his troubles with Tris she sipped on her drink and was mentally smirking as she saw Lynn and Ronnie sliding into stools not that far from where her and Four were sitting.

This should be an interesting night all around, she thought.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

"Jesus she is fucking killing me right now." Eric muttered into his drink as he watched Cass sitting at the bar by her brother.

He had barely restrained himself from going and grabbing her as soon as she walked into the bar with Victoria. Now he knew she was sitting there shifting her legs, crossing and uncrossing them every once in awhile, all to tease and torture him some more.

She also had to know that he loved it and with every fucking shift he was straining to see if he could catch just a small glimpse of what he knew was waiting for him underneath it. He also knew she had worn that dress just for him.

She knew how much her leadership tattoos on each of her shoulders across her collarbones turned him on. He was also proud as shit that she had went with them there when Victoria and the other minor female leaders had all gone for legs, spine or down an arm.

Not his Cass. She wanted to wear them proudly and for everyone to see. She couldn't get them on her neck as that was only for the Senior or Second in Command but even Max had loved her request to be able to get them on her collar bones.

Max chuckled at Eric when he drained his glass and clutched it tightly as his eyes were glued to Cass across the bar.

"Please tell me you two are finally going to get this shit done already?" Max said seriously.

Eric turned his eyes towards his mentor and superior, smirking. "Just fucking try and stop me Max."

Max snorted and shook his head. "Fucking finally. I have been sitting on that fucking shit for way too long now."

Eric shrugged not really caring about it being known or not. He had his own reasons for why they had waited and he would never regret them.

Max motioned for more drinks but Eric already knew he was cutting himself off after the next one. He had waited too fucking long for this to be drunk off his ass when it happened. He willed Cass to do the same and was happy to see that she sat nursing the same drink she had to start with.

Cass could tell the moment things took effect for her brother. He became fidgety and his gaze started to wander around. He lost his train of thought as he gaze went to this girl or that. She knew that he was ready the moment his eyes landed on Ronnie and Lynn.

Lynn and Cass shared a look and she knew that she could leave matters to their capable hands. Cass patted her brother's shoulder with a smile. "Hey Four, I am going to go catch up with the other leaders. You try and have fun tonight too. You deserve it you know."

'Oh yes you deserve exactly what is about to happen. It is only out of love though.' Cass motioned for one more drink and once she had it for them both she took hers and moved away from the bar.

Eric was already standing and saying something to Max as he did so. He took his own drink to another table down a ways from them and stood waiting for her by it. He took in everything as she walked towards him, which she did in that way he loved with her hips slightly swaying and a smirk on her lips.

He could also see that her own desire was amping up but also her nervousness. He loved that about her. That she could be so damn sexy, flirt, tease and torture him like no one else could or ever would. Yet she still had that innocence about her. She didn't let it hamper or hinder her. She had just been saving those parts they both held the most sacred for him and only him.

When she got closer to him he took her hand and pulled her closer. They both groaned just at the closeness of their bodies and the heat.

"You look fucking amazing Cass." Eric said close to her ear and smirked when he felt her shiver.

Her hand went to his chest and ran along the black button up dress shirt he had chosen to wear tonight. When he had stood she had felt not wearing underwear might have been a slight mistake as she took in the dress shirt that was tight enough to mold to his muscles. He of course had the buttons undone enough that she could see his own leadership tattoos and chest hair peeking through. He also had the sleeves rolled up to reveal those forearm tattoos she loved so much. His black jeans weren't much better in letting her keep her sanity as they hugged his ass and thighs perfectly.

"So do you Eric." Cass replied in a husky voice filled with the desire that hadn't gone away from the moment that serum entered her system.

Eric motioned for her to slide into her seat first and he would sit on the outside. She had already told him they should stay for at least some of the celebration but they both knew they were, even now when they were free and clear, going to torture themselves just a bit more. He also knew he wasn't going to be able to not touch her and he didn't want anyone seeing. Everything that came from when he touched her belonged to him and him alone.

When she was sitting down he moved himself into place and pulled her closer to his side. His eyes went to where she was looking for the moment and saw Four being flanked by Lynn and Ronnie. They looked to be heavily flirting with him but what had his eyebrow quirking was Four was doing it right back with this odd smile on his face.

He looked over to Cass who was smirking into her glass as she took a sip and he felt the laughter rumbling up. "I am guessing that little arrangement was orchestrated by you baby?"

Cass meets his eyes and shrugs with her wicked smile he loves so much. "I might have given him a slight….push. He can still choose to not act on shit but it doesn't look like he is fighting it too much right now."

Eric shakes his head with laughter. No it certainly did not look like Four was fighting anything other than how fast the three of them could get out of the door together.

Seeing Four though did bring back some other unpleasant thoughts and memories. Part of why they had waited so long had been because of fucking Four. Eric turns his head back to look at Cass and he reaches up to lightly run his fingertips along one side where her tattoos are on display.

The day they had gotten their tattoos together was the day before they had made the pact or agreement. He wondered if even without Four's interference if he would have made it with her anyways.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

They had met with leadership the night before the choosing ceremony in the tattoo parlor. They had been told just days before that they had both made full leadership and within six months from the time they had taken the positions and started training. Halfway through training for leadership they had to choose what positions they wanted.

Normally Second in Command would never have gone to a female. Cass was not normal by any means. Max had sat the two of them down and laid it out. They both worked as a team and were blowing through any standards set for leadership but only one could be chosen for Second to take Raze's place.

Cass hadn't even hesitated when she had said that there was no other choice. It needed to and deserved to be Eric. He could admit that at first he was a little miffed that she was just rejecting it and also a little miffed that she might be handing it to him. She didn't see it that way though. She laid out her reasons and his strengths. She felt she was more suited to the weapons development and tech side of leadership while she knew he could and would be able to handle the scope that Second in Command handled.

Max had even agreed with her by the end of it and as of that day he was in training for Second in Command. Before that day he had known what he and Cass had was something deeper than them wanting to fuck and playing games around it. He didn't know what they were but he slowly started to figure it out.

It was the night they got their tattoos that it hit him though. Anyone that tells you they got their neck tattoo and it didn't hurt is a fucking liar. They hurt like a mother fucker.

Cass and Eric had been torn between wanting to be tattooed at the same time but also being there with each other for those tattoos. This had been solved when Bud had just shoved two of the chairs together and then had them to where Cass and he could be facing each other.

Tori took Cass and Bud had taken Eric but he had wondered why Max and Harrison had been hovering near him as if poised for something.

Everything had started out fine. Cass had barely made a peep as Tori worked on hers while Eric had felt some discomfort but Bud had started on the lower portions of the tattoos first.

It wasn't until they got higher that Eric even realized he had started to scream. His own screams were interrupted by Cass yelling at everyone present and it brought him around.

"Don't you fucking touch him!" Cass yelled and when he looked she had moved so that she was now straddling him and had her hands on either side of his face.

Tori had just barely finished before Eric's had gotten to the spot she and Bud knew they would need both of them to help with. Max and Harrison were there to hold him down while the two of them would be working to get the one side done and then move on to the next. She hadn't even been able to fully clean Cass' tattoo before she was being ordered to leave her alone and Cass was scrambling over to Eric.

"Eric, baby look at me." Eric's eyes met hers and everything in him was clenched. "Eric you can do this without needing to be held down. I believe in you and we can do it."

"Cass…" Max starts with a frown and firm tone. He knew the two were hard and tough but even he had to be held down. He had also put two guys in the clinic with multiple breaks during the process. If he let Cass be hurt by Eric, even when he had no clue he was doing it, Eric would never forgive himself or them.

Cass locks eyes with the senior leader and thins her lips. "He can do it because I will help him." She dismisses the senior leaders continued looks of worry and looks back to Eric. "Eric you told me once you wanted to learn how I was able to take all of that pain he caused me and I said one day maybe. It was a joke on your part but never on mine. I am going to tell you how I got through it but you have to be with me on it. So I am giving you the choice, you can try it my way where you do this on your own. Be the first fucking leader to get his tattoos on his neck and not need to be held down. Or we can let the tradition stand."

She was challenging him and he knew it. She knew just what to say to push him and his buttons so that he had no choice but to meet that challenge. He was also worried as hell he would hurt her if they started up again and weren't there holding him. One look in her eyes though and the absolute belief in him, he knew it was going to be her way. It always had been so far, her and his way. He couldn't speak because he was still raw from the pain so he just nodded and let her know with his eyes.

She smiled softly at him and moved closer to his chest. They had them both reclined in the chairs and they had been holding hands as they were being worked on.

"Close your eyes now baby." She took the one hand that had automatically made its way to her waist when she had moved to him and put it over her heart. "Concentrate on nothing but that and imagine that is all you hear. Slow your breathing just like you did in the fear sims Eric, but let the sound of the beat of my and your heart surround you. There is nothing around you but darkness. Not a bad darkness but that darkness in the back of your mind that you know is always there. That place that holds our true selves safe for us, the one we don't let anyone else into. Go to that place Eric. Don't open any of the doors there just stand in the darkness."

She paused and listened to his breathing and felt his neck for the pulse there to know when he was there. Her voice was soft and soothing to him in that way she had always had with him.

"There is a barrel there Eric, just like the one with the fire where we burned our clothes when we first came. The flames are low right now so it isn't breaking through that darkness yet. It needs to be fed though. I want you to start opening those doors Eric, take out all of those fears about pain and death. All the thoughts or worries you have right now and I want you to put those into that fire. All of your emotions too….it all goes in. Give everything over to it until there is no dark left. There is only you and that fire."

She watches his face and slowly starts to see it and his body relaxing. His pulse evens out completely and his breathing goes normal. She smirks when she sees this because she knows he is ready and she nods. "Now open your eyes baby and look at me."

Eric opens his eyes and is seeing clearly but isn't feeling much of anything. Except for when he sees her. Somehow with the nothing that he feels surrounding him he feels something for her. She is smiling at him as she releases a breath and nods to Bud.

"Is that how you got through all of that baby?" Eric asked but his voice sounded strange. He had always had the ability to mask his emotions but right now they were completely gone.

Cass nodded again with a shrug. "I don't know how I came about discovering it. It was some kind of meditation thing I think but it didn't feel right so I started playing around with it. It wasn't until I figured out that I need to embrace that dark that I truly made it work for me."

Eric nodded in understanding but then couldn't move anymore as Bud had started to work again. The entire time Cass had remained on his lap and held his eyes. His hand still over her heart with their fingers threaded together. There might as well have not been another person there because all they saw was each other. All he saw was her there for him looking fierce and showing everything in her eyes they had never said to another fucking person. He knew he never would either.

She was also right and Max and Harrison hadn't needed to hold him down one bit. He would go down as the first leader to receive their tattoos on the neck and not have to be held down, all because of her. He had known then how deep things were for him and just them in general. He hadn't known what he was going to do about it though until the next morning when Four confronted him.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Cass frowned as Eric moved his fingers over her tattoo. He was lost in thought and she was trying to figure out what he was thinking about so deeply. "Do you remember the night we got these Cass?" Eric asked in a soft voice near her ear.

"Of course I do Eric. Was that what you were thinking about?" She quirked an eyebrow and turned so that she was facing him a little more.

This positioned her so that he could now bend just slightly and graze his lips along the same tattoo he had just been lightly touching. His lips curled into a slow smile as he heard her low moan and felt her body arching.

"How could I not think about that night, Cass? That was when it really started for us baby." He said seriously as he trailed kisses along her skin, eyes closed and breathing her in. "I had planned to take you that night you know. To end our game and finally make you mine."

As he was talking he had started to nip, bite and suck along her shoulder. He had also started to trail his fingers along her chest, dipping in and out of her exposed cleavage and making her moan.

Cass swallowed and nodded a little. "I had thought you would but Max and Harrison had other plans."

Eric huffed a little and moved his lips higher along her neck while his hand dipped lower. "I was cursing the fuck out of them at the time as they bought us round after fucking round."

Cass' head fell back a little but not far because his free hand had moved to the back of it and locked her in place. "Me too." She got out in a gasp when he locked onto her pulse point.

"Your skin tastes so fucking good Cass." He groans as he continues to move his lips over just her exposed neck, shoulders, and ear. He can't go near her mouth yet because if he does it will be game over for him.

"Eric." Cass moans as the hand that had been slowly working lower was now sliding up her skirt and along her thigh.

He smirks into her skin as he trails his fingers lightly along the soft inner thigh. "Open your legs for me Cass." He commands right into her ear in a purr.

She doesn't hesitate as she lets her legs fall open more for him. She is rewarded when he slides his hand up further, teasing all along the way, until those fingertips brush against her wet heat.

"Fuck" She gasps out and closes her eyes.

"Not yet, but fuck if I won't have you soon." Eric growls as he slides a finger through her folds and groans at how wet and hot she is for him. "For now I want to hear you moan for me baby."

He parts her slowly and bites his lip as his nostrils flare and both of their breathing picks up. He casts a brief look around as he slides his finger slowly into her and closes his eyes at how tight she is around just his finger.

"Eric….gods that feels…" Cass is gripping the table with one hand and his thigh with the other as she moans.

Eric starts to pulse his finger into her. He feels her start to move her hips a little but also her muscles, that are already so damn tight around the now two fingers he has in her, start to tighten and release and he moans right along with her.

"You're killing me here baby." He groans as he begins to kiss along her neck to her jaw. His thumb has moved so that it hits her clit with every thrust of his fingers into her pussy and her moans are building, letting him know she is close.

It also is making him harder and feeling like he is about to snap.

Cass is so damn close and it just escalates when two things happen at the same time. In her bid to grab anything as she was in the midst of being lost in Eric's touch she had grasped his thigh. Eric had started to kiss along her jaw and as if the two of them timed it, his mouth brushed against hers as soon as her hand brushed against and then grabbed his straining cock through his pants.

They both snapped as Eric lost it and claimed her mouth finally but still kept with his attentions from his fingers. It was fierce and deep as he delved into her mouth with his tongue just as his fingers were delving deep into her as well.

He was swallowing her moans and gasps as they increased and he could tell by the way she was grasping at those fingers with her muscles and his cock with her hand that she was coming undone for him.

When he was sure she had finished he lessened the kiss until he was hovering just above her lips and they were both trying to calm down. She was panting but still hadn't let go of trying to get more of him in her hand.

With a growl he pulled back, pulled his fingers out of her and grabbed her hand. "It's time to go Cass." He said right before he lifted his fingers to his mouth and watched her eyes as he tasted and sucked her juices from them right there.

She moaned but he wasn't any better as he closed his eyes and relished the taste of her. When he opened his eyes again she was biting her bottom lip. "Now Eric." She got out in a voice thick with lust.

He wasted no time in standing and pulling her out with him. She barely had time to grab her clutch purse before he was pulling her along with him and out of the bar.

She didn't care where he took them just as long it was somewhere she could have him, all of him and right then.

As Eric stalked through the corridors, glaring their way clear, he held Cass close to his side and had to mentally restrain himself from just saying fuck it to his plans and finding some unused room or something to take her right then. It was torture, that walk, not matter how fast the pace they were setting. The party around them was in full swing and it reminded him so much of that night one year ago.

Once he again he was pulled into the memory but it was welcome if it could distract him enough so he could keep himself together until they reached his destination.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Eric had groaned himself awake the next morning after Max and Harrison had insisted that they take the two new leaders out to celebrate not only their tattoos but that Eric had been able to get his without making a peep or being need to be held down.

Thankfully he didn't have a hangover but they had gotten in too late and needed to be up too damn early. He was already dreading the day in general. Having to be apart of training and having to do it with fucking Four. It was way too damn early and he had way too little sleep to have to deal with the asshole.

Not to mention all of his plans for Cass had been blown to shit by being taken out for the night. So when he finally made his way into the control room to endure the hours long process of watching the choosing ceremony to prepare for how many initiates they were looking at, he was in a less than stellar mood.

It didn't help things that he was forced to sit by none other than number boy himself or that said asshole was shooting him glares already.

Not even ten minutes after he had sat down he had to listen to Four mumbling passive aggressive shit under his breath. With sigh he turned his glare onto the former stiff.

"What the fuck is up your ass this time? Other than that stick you have shoved up it normally?" Eric tries to keep his temper but it is just so hard with the dick.

Four's head snaps over to him and he snarls at him. "You think I don't know the game you are playing with my sister? You need to leave her the hell alone and just keep to the tramps that throw themselves at you."

Eric's fists clench as tight as his jaw. "You don't know fuck about Cass and me. You also know shit about your sister and you sure as shit aren't her father, so I suggest you butt the fuck out."

Four's face darkens and his own fists clench. "I know my sister. I also know that while you are fucking anything that moves you are letting it be known that she is supposedly yours. We both know how this is going to end though, Eric. You are going to use her like you do everyone else and then leave her. Cass isn't like other girls and once she commits to one person that is it. You don't deserve that loyalty when all she is to you is some sick game or toy, one that when you get tired of it you will throw away. I fucking won't let you do that to my sister."

Eric couldn't remember exactly what he had said in return but it didn't matter. The end result was the only result that was going to happen from the start. The two had launched themselves at each other and had to be pulled off by the other leaders present as well as the people in control.

After making sure they were both cool, Max had separated them to watch the ceremony well away from each other. All the rest of the morning Four's words had run through his head along with what he had determined the night prior. There was no worry for him about what Four thought he knew in regards to how many girls he had actually been with. It wasn't anywhere fucking near the rumored amount and he never hid or lied about that shit to Cass. That wasn't what was bothering him about Four's words. He knew she was more but did she know?

That was all that he could think about and it was driving him crazy.

xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

They finally reach his destination, his apartment, and he is pulled from his memory as he enters in his code quickly. As soon as they are in and the door is shut he has her against the wall. All he can think about after that is claiming her mouth, neck, breasts…..every fucking inch of her that he can get to quickly. So he proceeds to do just that while Cass has other plans.

Her hands move to his pants and is hurriedly undoing them while Eric is killing her slowly with his mouth. When she finally gets them open she shoves them and his briefs down and moans as he springs forth, ready for her.

She also moans because he has managed to push the top part of her dress down enough and is now using his teeth, tongue and lips on her nipples. Her hand closes around him and he pauses long enough to let out a hiss of air and groans deeply. He kicks off his shoes hurriedly so that his clothes can be stepped out of and kicked aside.

"Fuck baby." He lifts his head from her breasts to claim her mouth but she stops him by grasping him harder and growling.

"I want this in me now Eric." She demands of him seriously in between her pants. His nostrils flare even more as he gives a wicked smile and pulls away from her, getting her hand away from him when she would have tightened on it to stop him from going.

"You want it bad don't you Cass?" He asks this as he is leading her slowly into his living room, walking her backwards while his hands slip under her dress to cup her bare ass.

"Gods...yes I want to so bad." She gasped out when he suddenly stopped and worked a hand up into her hair and pulled until her head was pulled back.

"How do you want it Cass?" He growled the question out but already knew the answer. There was no other way for it to be for them this first time.

"Hard, fast…...I want everything Eric. I want every bit of you inside of me, deep inside of me." She gets out between moans and pants because Eric had started to kiss and suck on her neck as he rolled her nipples between his fingers.

He pulls back and looks at her seriously, his forehead furrowed with the restraint he is trying to have. It breaks though looking into her eyes and seeing everything that has been building up between them. She has waited too long for him to be ready, for him to know that he has proved himself to her.

"Lift your dress up and bend over the couch Cass." He demands as he spins her around and is already moving her into position.

Cass bends over the back of the couch and moves the dress further up when he flips it to expose her. She smirks back at him when he kicks her legs apart slightly. Something he took pleasure in doing during training when he decided she needed a little help with her forms or when firing a weapon.

The smirk quickly turns to a gasp as she feels him rubbing at her entrance. His eyes locked onto hers and he smiles wickedly. "Don't you fucking look away Cass. Keep your eyes on me while I take you." He sees her nod and swallow, her skin flushed with her eyes wide. "You ready baby?"

"Yes Eric." She uses that tone with him and shivers as she sees his shiver of pleasure just before he slams into her in one quick thrust.

"Good girl Cass." He gets out as he holds her eyes and stills in her for just enough time for her to adjust to him.

He can see her strain in taking him but he can also see she doesn't want him to stop. In the few seconds he was stilled inside her, she has already started to show him just what she can do with those muscles he felt working over his fingers and it has him growling. It also has him grabbing her hips and slamming into her over and over.

The entire time she can't tear her eyes from his even as each thrust makes her feel like her eyes should be rolling into the back of her head. Add to that the fact that he has reached around her to start working on her clit and she can only cry out, gasp or mumble unintelligibly.

He is unleashing himself for her and only her as she sees his nostrils flared, his bottom lip between his teeth but it is his eyes holding hers that she sees it most.

"Eric...I'm going to…" She trails off and moans as he pinches on her clit and groans along with her.

"I'm right there Cass. Together baby. I need it to be together." With a frown he realizes he wants her closer, needs her closer for this. The hand that had never left her hair moves to snake around her chest and hauls her against his chest.

"I'm with you Eric. Always." She pants out as he resumes his thrusting motion into her. Her head is still turned to look back at him over her shoulder but his hand has moved from between her breasts to lightly go around her throat.

Eric smiles as he applies very light pressure to her neck. "All yours Cass. Together now." He grunts out the last part as he slams into her twice more and only allows his release when he feels her convulse around him.

As soon as he felt that her claimed her mouth again and took in her pleasure as he was giving her his too. Their chests were heaving as the stood there panting into each others mouths and still kissing.

They aren't done, not by a long shot. His hands start to move to remove the only thing that is keeping her from being against him in the way he has only dreamed about to date. He never breaks the kiss or moves out of her as he unclasps the belt then unzips the dress.

It is only when he needs to let it fall from her to the floor that he pulls out of her and grins at her whimper and trying to pull him back. She gives a small huff and she whips around as her hands go to the last bit of clothing he has on. With a grin she pulls hard until all the buttons pop off and his shirt pops open.

"Oops." She says with a shit eating grin.

Eric only has time to quirk his eyebrow before he is groaning when she moves her mouth to stake her own claim along his neck. Between that and her hard nipples rubbing against his chest he is hard as hell again.

Cass pushes the shirt off his shoulders and down his arms as she bites and sucks along his neck. She knows he is about to snap again because she can feel his muscles bunching up in his arms and she smiles into his neck.

"I promised I would have you in my bed before the end of the night Cass and fuck if I am going back on that promise. I don't intend on us leaving it until tomorrow sometime." Eric says this as he has already pulled her so that her legs are wrapped around his waist and is kissing her between all of that as he walks with her.

He doesn't even strain a bit when he reaches out and flicks on the bedroom light while still holding on to her with one arm. He is still kissing her as he lays her down on the bed and then starts to kiss down her body. His hands moving to remove her boots then move over her.

Cass shivers in pleasure and nerves causing it to draw Eric's attention. He pulls back and frowns at her a little. "Are you ok Cass?"

Eric looks at her as she bites her lip and nods but he sees she is nervous about something.

"I'm fine Eric." She finally gets out in a breathy voice.

Eric scowls at her because they talked about hiding shit from each other. "No you aren't, you are nervous about something."

Cass huffs a little and swallows. "This will be the first time you are seeing me naked and…"

"Seriously? You are worried about…"

Cass rolls her eyes and shakes her head. "Not about the naked part but I am nervous you won't like what I had done."

What she had….

Eric pulls back and looks down on her from his knees to take her in. She looks gorgeous there on his bed and at first he doesn't see what she might be talking about until he gets to just under her breasts and he sees the tattoos on her ribs that go down to her abdomen and then wrap around so that they form a v just above her pelvis.

His breath picks up and his nostrils flare but he starts to get the biggest fucking grin as his gaze moves to what exactly is forming that v right above what he has always considered his and his alone.

From the upper rib down it was a Polynesian tribal art pattern that followed her curves perfectly. Until it got to the hip area where the pattern became the exact maze and symbol patterns from his forearms.

His hands hand started to move over and ghost across the patterns and he couldn't even help how happy seeing that made him.

"When did you get this Cass?" He finally got out after he had kissed back up her body and claimed her mouth a long, deep and meaningful kiss. Letting her know how much he liked what she had done.

She sighed after he pulled back from the kiss, from relief that he liked it and from the kiss itself. "That next week after…." She trailed off after he cupped her cheek and smiled as he nodded. "I never doubted what we were Eric. I understood you needing to prove it to me, but I knew already."

"I never wanted a doubt to be able to be cast by anyone Cass." His mouth hovered just above hers as he said this firmly.

This time it was Cass pulled in by a memory spurred on by his words. He had said almost the exact same thing in the almost same manner to her one year ago.

Xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx

Cass hadn't seen Eric for most of the day. He had been busy with the new training group that he was supervising with Four and she was in and out of the Dauntless born group as well as having been to a meeting with Erudite. She had been dragging ass for the first part of the day after having been kept out way later than she had planned by Max and Harrison.

Now the leaders wanted Eric and her to be at another party to officially celebrate their making leaders and getting their tattoos. She had smirked when she was passing a group of members and she heard them whispering in hushed tones about Eric and him getting his leader tattoos. He was already feared and built a reputation for himself during training even. They both had really but Eric more so.

He was feared by most and respected by many. After that though it just built on it like a snowball. She had missed lunch and was just making it back into the compound by the time dinner rolled around when she was pulled into arms and then pressed against a wall almost as soon as she entered The Pit.

"You missed lunch." Eric said with a deep frown on his face. He wouldn't admit that he had been waiting in The Pit for Cass to anyone else. He didn't need to admit it to her because she would already know.

He could count on one hand the amount of times they had missed meals together since early on in their training. No matter what, even if it wasn't in the dining hall, they ate together.

Cass sighed tiredly and nodded. "Sorry. I messaged you but I was stuck at Erudite with the new R&D Head. The man is an imbecile. I do not know how he made it to that level but I think he might not be for that much longer. It is sad when a leader from another faction knows more about how your department works than you do."

Eric smirked as he looked her over. His body was pressing into hers his mouth so close to hers and he had every intention of stealing her away for the hours before they had to meet with the leaders and making good on what he had wanted to do last night. Then the words from Four and last night in the parlor started to play in his head and he couldn't help the scowl that came over his face.

"You aren't just some girl I want to screw, Cass." He ground out angrily as he held her eyes.

Cass was confused and shook her head. She had been in a slight daze from how close they were, how much she wanted for all the teasing to be over. His words pierced through the haze and left her frowning.

"I never said you thought that, Eric." She tilted her head confused.

"No, but others do." This time he growled and his firsts clenched.

"Well then it is a good thing I don't give a fuck what others think, Eric." She gritted out, wondering where the hell this was coming from.

"I shouldn't care but I do. I never want anyone to be able to cast a doubt on this Cass. I don't want anyone to be able to make you doubt that you are more. We are more." His forehead was furrowed and he held her eyes with such intensity.

Cass swallowed and nodded. "I know, I just don't know…."

"You don't know what we are…." Eric finished and sighed, his mind whirling. She was his and he already knew that they both knew that. Hell the entire fucking faction knew that. She had no reassurance that he was hers just as much though.

How could he prove that to her? His mind connected the dots and then he was moving before he even informed her of what he was doing or where he was going. He had a hold of her hand and was pulling her along with him as he stalked his way back up to the leader's offices.

He knew for a fact that Max and at least Harrison would be in the senior leader's office. He knocked and Cass was looking at him with a frown. "Do you trust me Cass?"

Cass' breath caught in her throat at the intensity and need in Eric's eyes and voice. So she did something she had only done once before. "Yes Eric." She replied in a tone that conveyed submissiveness but that wasn't what it was truly for them. It was so much more and she saw his relief and happiness.

"Good girl Cass" He returned her submissiveness with dominating tone but again it was so much more. For them it was them saying with words and actions all that they would never give anyone else.

He had barely got that out with a smile and in a husky voice when the command of enter was being called out.

He tightened his hold on her hand and pulled her into the office with him when he opened the door. He was right Max and Harrison were both there but so was Victoria.

Eric mentally shrugged and thought that it might as well be all of leadership for this anyways.

"Eric. Cass….I thought you two would be grabbing dinner and getting ready for the night." Max said with amused look, head tilted. It took on a smug look when he saw Eric holding Cass' hand and pulling her to his side.

"We will be shortly but there was something we needed to take care of before we do." Eric said firmly.

Max quirked an eyebrow and motioned for Eric to go ahead.

Eric cast one look to Cass, who smiled at him, then took a breath and tensed his body. "We would like you to marry us. Tonight."

Cass tried to not show any reaction but that was not something she had been expecting. She wasn't going to object but she did put a hand on his chest and will him to look at her. She didn't expect this of him and was worried he thought she might.

Eric forgot about the leaders for a moment as he faced her and shook his head. "No I don't think you expect this of me Cass. That isn't what this is about. I need you to know I am yours and only yours no matter what. I need you to know that and not doubt it but I need to show you, to prove it to you."

"Eric there isn't any need…" She was stopped when he cupped her cheek and tilted her head to look at him. They held eyes for a while and she saw that he wanted this too and not just to prove himself to her. With a sigh and a small smile she nodded.

Eric tore his eyes from her and looked back to the leaders who looked a little stunned but also pleased. Cass nodded to Victoria who was looking at her as if to ask if she was really ok with it.

After Max had recovered from his own shock he quickly pulled out the certificates needed, then performed a small ceremony. They hadn't wanted or needed to add anymore vows than were already in the standard one.

"Well we have something to announce at dinner tonight." Max said as he clapped his hands after he had given a copy of the certificate to them but also set it up to be filed with Candor in the morning.

Eric frowned and shook his head. "No, not yet. I don't want it announced yet." He looked to Cass and steeled himself. A year, could he hold out for a year? Gods he fucking hoped so and that she understood. "Not until next year. On this night next year you can make the announcement."

Max frowned and looked between the two. "So you don't want me to file it until then?"

Eric shook his head with a scowl that was defeating the fucking purpose. "Fuck no. File it now. We are married as of tonight and you can announce it as our fucking anniversary or some shit. I don't really care to be honest that isn't what this is about." He had never broke his gaze from Cass so he saw the realization dawn on her.

She groaned a little as she closed her eyes and opened them again with the longing she knew they were going to be feeling before the end of that year and badly. She saw how important this was to him though and knew that in a way, deep inside her it was just as important to her too.

He wanted to show her he would be as committed to her in every way, without the physical getting in the way. He wanted to show her she was more but holding off from taking their relationship that final step, not until for a year, he had shown them both what they meant for each other.

Cass reaches up and pulls Eric to her for a kiss, completing what was started that night in the Max's office. They don't pull back and they don't need to. Eric slides into her as her tongues slides into his mouth.

She moans into his mouth as her body arches up into him. She had known a little of how large he was just from what she could see outlined in his pants but nothing had quite prepared her for how much he stretched her or how right it felt.

It didn't stop her from trying to make herself even tighter around him as he moved slow at first inside of her. Soon though he was slamming into her once again as she begged him for all off him.

"Feels so fucking good Cass." Eric groans out as he holds her hands to the sides of her head, her legs he had moved to be on either side of his head.

Cass couldn't get out a reply as her head was thrown back and all she could do was moan, grunt and cry out with every body shattering thrust he made into her.

She couldn't even warn him verbally when she was climaxing but he knew by the way her walls gripped him and pulled him in even further. This had happened twice already but he hadn't stopped or let himself release yet. She could feel it in the tension of his thighs as they slapped against her with his moves into her.

"That's it baby, come for me because I am ready to give you it all." Eric growled as he had been holding his own release for as long as possible. On the third time he knew he couldn't hold out anymore and he roared his own release when she finally managed to get out one word in her climax.

"Eric!" tore from her throat as he body shook violently and he went deeper than he had earlier. Both of their bodies were trembling as he collapsed beside her and pulled her to him. They lay there panting and trying to get their breathing under control for long minutes before Eric swallowed and looked over to Cass.

She had this cat ate the cream smile of satisfaction, her skin was flushed beautifully and her chest heaving. He gave a little chuckle at her smile but also that he knew he had to have a shit eating grin to match hers.

She turned her head to look at him and her smile widened. "Was it worth the wait?"

Eric quirked an eyebrow and never lost his smile. "Every fucking minute of it Cass. I wouldn't have traded it for anything. You?"

She sighed blissfully and shook her head. "Wouldn't have traded a minute of it either Eric."

Eric's grin changed to a little of a smirk and he shrugged. "Although, I wouldn't have minded you having been slipped a damn serum a little earlier. I think I really enjoyed our little torture sessions too much to give them up Cass."

Cass smiled wickedly at him and raked her nails down his chest lightly. "Who said we would ever be doing that Eric? It's us. When have we ever given up on a little torture?"

Eric shook his head with his own wicked smile. "Never baby. It's just how we want it." He sighed as he started to kiss along her shoulder and then a thought struck him. "You gave him a push? The same kind of push that was arranged for you by your friends?"

Cass laughed and shrugged. "Not exactly the same but something along those lines. And at least I didn't leave him hanging out to dry without any kind of relief."

Eric laughed into her shoulder. "You set it up with Lynn and Ronnie too?"

Cass smirked. "I might have let it slip that I might be able to help her see a longtime wish and fantasy of hers come true if she was at the right place at the right time. Oh and that she get a few things for me from Ronnie."

Eric's nostrils flare in desire as he moved to pull her until she was straddling him. "Hmmm….well that sounds like a story for later then….." He purrs out just before he guides her down on him as her head falls back and she hums her agreement.
