Her knees were actually trembling by the time that a knock sounded at the door.

Tris was no stranger to fear, though she was well versed in appearing braver than she actually felt.

This was one of those times, as she stared at the door to her apartment, willing herself to open it.

He had knocked so gently that she barely heard it over the sound of her rapidly beating heart. So quietly that she probably wouldn't have heard it had she not been waiting for it.

She stood in front of the door with her back straight, face stern, slowing her breathing until it was nice and even.

Only then did she open the door.

"Hi," she said breathlessly.

"Hi," he repeated with a smirk on his handsome face.

She stood to the side in an unspoken invitation. He had enough room that he needn't have brushed against her on the way in, but that didn't stop him.

Tris breathed in his scent as he slid by her, their chests touching for several long seconds. He had just showered. She could tell because he smelled strongly of soap with just a hint of cigarette smoke from his jacket.

She pushed the door closed with a gentle snap without taking her eyes off of Eric.

"Hi," Tris repeated, suddenly feeling shy.

He raised an eyebrow, looking amused.

"Don't tell me you've changed your mind?"

"No," she said quickly. "I'm ready."

He took a step forward, leaving just a whisper of space between them. Tris pulled in a deep breath to steady herself. Her knees were still wobbly and she was unsteady on her feet.

Slowly, Eric brought his hand up to touch the tattoo on her collarbone with his long, pale fingers. He then placed his palm flat against her chest, over her heart.

It was almost romantic, if you overlooked the dangerous glint in his eyes.

"You're afraid," he said. It was not a question.

Tris hesitated before speaking. She knew he could feel her rapid heartbeat under his hand, maybe he even noticed the way she shivered under his touch.

"I'm not afraid, I'm nervous," she corrected him, wanting to cringe at her admission. She knew better than to show weakness in front of Eric.

"You don't have to be," he said. Tris was surprised by the tone he used in his reassurance, by the way his eyes softened. She had expected him to laugh at her. "I'm not going to do anything you don't want me to."

Tris nodded slightly, taking in the shockingly gentle expression on his face. She had never seen Eric look so caring. It reassured her more than his words had.

The way he stood there with his hand on her heart, looking quite vulnerable, was not a sight she would soon forget. It was something out of a daydream and Tris soaked up the moment, not knowing when, or if, she would ever see him like this again.

He let his hand fall away from her heart.

In a moment of recklessness, Tris wrapped her hand around the back of his neck and brought him closer until his face was level with her own. Their foreheads pressed together now, their lips brushed with every breath they took, yet Eric still did not make a move to kiss her.

"Be brave Tris," he whispered, and every syllable felt like electricity against her lips.

She closed the distance between them, pressing her mouth firmly against his, relieved when he didn't hesitate to respond. The kiss was devestatingly slow and sweet, like nothing she had ever experienced with him before.

Her hand crept up the back of his neck into his hair and then his hands were suddenly on her hips, fingers splayed across her backside, gripping her as if he thought she would disappear at any moment. His thumb stroked the skin he had found between the hem of her shirt and her jeans and Tris bit back a gasp at how good it felt to have his hands on her bare skin.

She felt his lips quirk against her own, before he kissed her again, just the tiniest bit harder.

This hadn't been what Tris was expecting when she thought of being with Eric, but she wasn't about to complain. Since initiation had ended, she had spent most of her waking time thinking of Eric and it felt so good to finally have him in her arms, even if it was just for one night.

Their kiss grew more intense as he palmed her ass through her jeans, and she fisted her hands in his hair. She was a little surprised when she felt Eric's tongue on her lip, but she opened her mouth to give him access anyways, surrendering herself to his ministrations.

His tongue stroked hers, almost lazily and she all but swooned. Her knees were wobbly again, this time from the adrenaline coursing through her body.

Tris suddenly had the unbearable urge to bring Eric closer, though there was no room left between them. He was gripping her ass tightly in both hands now, pulling her towards him so that her hips were flush with his. With a sudden jolt of awareness, Tris felt Eric's erection against her stomach, hard and heavy, even through the fabric of his jeans.

Her hands were on Eric's chest, grasping at his shirt to pull him even closer as his mouth plundered hers. She moaned at the feel of his hard muscles beneath his clothes and the sudden desire to rid him of his clothing was overwhelming.

She pushed his jacket off his shoulders without really thinking, just wanting to feel more of him. It landed on the ground with a soft thump, but neither Tris nor Eric paid it any mind.

"Bedroom," Eric muttered, only pulling his mouth away from hers long enough to get the word out.

"Mmm," Tris agreed. "Behind you."

She thought he would lead her there inbetween kisses, but it seemed Eric had other ideas. With an impressive show of strength, he lifted her from the ground with just his hands on her ass. Tris wrapped her legs around his waist, anchoring herself to his body. Her arms worked their way around his neck, drawing him back in even as he walked towards her bedroom door.

Eric dropped to his knees on the bed before he let go of Tris, letting her fall onto the mattress with a soft bounce.

Slowly, he reached out with both hands and let them settle on the curve of her waist. She didn't stop him as he pulled at the hem of her shirt, tugging it upwards to expose the pale skin of her midriff. With a thundering heart, Tris raised her arms and he pulled the shirt over her head.

Breathing heavily, Tris settled her eyes on Eric's face, searching for his approval. His expession was dark and full of lust, and she felt her nerves relax just a little.

Emboldened, Tris sought to remove him of his of his own shirt, though she was much clumsier than he had been. She was rewarded for her efforts by a sight unlike any she had imagined. She knew Eric was fit, but seeing his sculpted body up close and personal made her stomach flutter. Almost of their own accord, her hands reached for the button of his jeans.

This was it, she thought, fumbling with his pants. Her fingers were trembling, but she was determined. Eric seemed to know it too. He looked down at her through heavily lidded eyes, patiently waiting for her to undress him.

Something in his expression gave her the courage she needed to pull his pants down around his knees, exposing his underwear and the outline of one very large, very erect penis.

She hesitated for a moment too long and Eric noticed.

"What's wrong?" His voice was amused, but there was a breathy note to it that he couldn't hide.

"Nothing," she told him, just as breathlessly. "Stand up and take your clothes off. All of them."

He did as she demanded, kicking his boots and jeans off. He pulled his boxers down with a smirk that Tris didn't notice because her eyes were further south.

He was much bigger than she had expected and she found herself wondering how on earth he was supposed to fit inside her.

"What now, Stiff?"

She forced her eyes back up to his face to find him grinning. His confidence made him even more attractive to her and Tris smiled back.

"I suppose I'm over dressed."

"Let me," he offered as he descended on her before she could argue. He opened the button of her pants with a steady hand and slowly peeled the material down her legs until she lay before him in nothing but her undergarments.

The resulting silence was long and Tris felt a hint of her earlier doubt return. What could he possibly see in her? She was so small and underdeveloped compared to most girls around Dauntless.

Eric suddenly straddled her, leaning over her body until their faces were close, his erection pressed against her thigh.

"You're so fucking sexy, Tris," he whispered in her ear. Her heart was thundering in her chest, so loudly that she wasn't sure she heard him correctly. She placed her hand on his chest and pushed lightly. He backed off just enough so that she could see his face, clouded with lust. He wasn't lying. He found her attractive, even with her clothes off. Her sense of relief was palpable.

"Let me touch you," he ghosted his hand over the tattoo on her collarbone as he spoke. "Let me make you feel good."

She nodded in response, a little light headed, even before he leaned in for another heated kiss. His hands went to her sides and trailed slowly up until he reached her bra. He took his time taking it off, one clasp at a time.

Tris honestly hadn't realized he could be so patient and gentle- the complete opposite of what she had come to expect of him.

She gazed into his eyes with wonder as he slid her bra straps down over her arms so slowly, as if savoring the moment.

Never in her life had she felt so naked and vulnerable as she did right now, as his eyes devoured every inch of her exposed body.

He shifted slightly, his erection rubbing against her thigh again, leaving a wet trail of his pre cum accross her skin.

"You're shaking," he whispered, fingers pausing on the edge of her panties.

"Don't stop," she demanded loudly, arching her hips up off the bed.

He grinned at her, pulling her underwear down her legs until she was completely bare beneath him.

His breathing was labored, as if he had done more than simply undress her. She was glad that she wasn't the only one affected by the absurdly intimate situation.

His eyes roamed over her body again, huge, dark pupils contrasting beautifully with his stormy gray irises.

She blushed a little under his invasive stare.

"Are you going to touch me or just look?" Tris asked cheekily.

He chuckled a little, but didn't immediately move.

"Patience," he rumbled deeply, and the sound of his gravelly voice made her want to rub her thighs together. She might have given in to the urge, had he not chose that moment to run his hand up the inside of her leg, so gently it almost tickled. His destination was obvious, but Tris still startled when his fingers brushed her wet folds. "We have all night."

His thumb found her clit and he began to rub her with devestatingly slow circles.

"Oh, god," she gasped, closing her eyes and throwing her head back against her pillow.

Eric laughed quietly.

"I'm barely touching you, Stiff."

"Don't you dare stop," she groaned, spreading her legs a little wider. He circled her clit faster, turning her into a quivering mess in a very short amount of time. His touch was beyond what she could have hoped for, an all encompassing fire blazing inside her, so hot that she was sure she would burn up and all that would be left was ash.

Eric moaned suddenly and her eyes flew open. He was stroking himself as he played with her, the muscles in his arm straining as he pumped his cock lazily.

He had never looked more appealing to her than he did in this minute.

"Can I do that?" Tris asked him boldly.

The surprise was clear on his face, but it only took a moment for his smirk to return.

He took her hand in his and brought it to his erection. When her fingers wrapped around his length, his eyes fluttered closed for just a second. Then he was watching her hand with rapt fascination as she slowly explored him.

Being a virgin, Tris had never held a dick before. What surprised her the most was how soft his skin was, like steel encased in silk. She could feel the blood pumping beneath her hand. He was hot and throbbing and she loved touching him.

"Fuck yes," Eric muttered as she stroked him gently, marveling at the incredible feel of him in her hand. He rocked his hips forward a few times, meeting her thrust for thrust. At this point, he had stopped pleasuring her, but Tris didn't mind. She watched a flurry of emotions contort his beautiful features as he lost himself to the rhythm.

"Oh," Tris gasped as he slid a finger inside of her with relative ease considering she had never been penetrated before.

"Fuck," he hissed, curling his finger inside of her, thrusting in and out slowly. "So tight..."

She inhaled sharply when he added a second finger. She had begun to feel the first hint of pain as he stretched her uncomfortably, but it felt good too. Just as she had hoped, Eric knew what he was doing.

Tris gripped his dick tighter in response, coaxing a loud moan from his lips.

"You like that?" He asked, thrusting his fingers deeper and faster. She tried to match his pace, but her movements were sloppy and unpracticed. "Tell me how much you like it, Stiff."

"I like it," she gasped. "I like it a lot."

"Let me hear you," he demanded, pressing deeper.

She moaned loudly for him, but it had the complete opposite effect that she had hoped for. He withdrew his fingers, leaving her feeling empty. Tris quickly focused her eyes on his face, confused.

To her complete shock, Eric brought his glistening fingers up to his mouth and tasted her arousal. He hummed his approval as he sucked on his fingers, watching her reaction with a smirk.

She was speechless and Eric seemed to know it.

"You taste so fucking good, Tris," he whispered, leaning forward to press his lips against hers in a chaste kiss. He pulled away too soon for her liking, leaving her disappointed and leaning towards him. "You ready for me?" Eric asked, his voice so low and gravely that Tris nearly swooned. His hand was on his dick again, stroking himself a few times before leaning forward to press against her center.

"I'm ready." She was determined.

"Are you sure this is what you want?" He smirked down at her as he rubbed the head of his dick against her slick folds. Her eyelids fluttered and she moaned, digging her fingernails into his shoulders.

"Please. Just fuck me, Eric."

He obliged her, but at a glacial pace.

Tris wondered why he was going so slowly, she felt fine, it barely hurt at all, when-

"Ah," A startled little whisper escaped her lips when he tore through the evidence of her virginity with one shallow little push.

Oh, that hurt.

"You okay?" He whispered, drawing her attention back to him. His eyes were half closed, heavy with lust and a hint of concern. His jaw was clenched tightly and his forehead wrinkled, as if he was concentrating very hard. He was trying not to hurt her, she realized.

"Yeah," she said reflexively, and it wasn't quite a lie. The pain wasn't insurmountable. She could handle the discomfort if it meant being with Eric. "Keep going."

He pushed in a little deeper, paused, as if the action pained him, then slid in to the hilt. He froze again and swallowed so loudly it almost seemed to echo through the room.

Tris released the breath she had been holding and her eyes found his once more.

"Go on," she urged, wrapping her legs around him. He nodded once, just a little, looking so serious that she couldn't help but to smile in amusement.

"What's so funny?" He asked, pulling out almost all of the way. Her smile faltered a bit when he thrust his hips upward. The stretch stung like nothing she had ever experienced.

He did it again, pulling out, pushing back in.

It took a minute, but she couldn't deny it was beginning to feel nice and it was growing increasingly difficult to concentrate on anything besides where their bodies were joined.

With each long, slow thrust Eric seemed to relax a little more, the features of his face twisted into a smirk as if he knew exactly what she was thinking.

He leaned forward, changing the angle of penetration as he nipped at her neck with his teeth. Her muscles clenched around him in response to the pain and he moaned into her neck appreciatively.

Tris tightened her grip on his shoulders when he whispered her name into her neck, his voice breathy and uneven.

She was lost in the moment, Eric sliding in and out with a deliberate slowness that was making her whole body respond. Her hips began moving of their own accord, rolling gently with Eric's thrusts, as if she had done this before.

Meanwhile, Eric's hands are everywhere, pulling at her hair, holding her face so that he could kiss her jaw, running over her bare breasts. She bucked her hips when he pinched her nipples, driving his perfectly timed thrust even deeper.

"Mmmm," Tris moaned in appreciation when he was able to recreate the sensation. It didn't hurt at all now and she found herself wishing he would go faster, harder, something. She pulled him in closer with her heels on his back, urging him on.

He seemed to understand what she wanted, snapping his hips upwards with intent, developing a faster pace as he drove himself inside of her again and again.

Tris actually whimpered out loud, not from pain, but from the pleasure of it all. There was heat building inside of her, all over, but most prominently at the spot that Eric was hitting each time he slammed his dick into her. It was intense and Tris was lost, wondering how she could stand the heat.

It wasn't easy. She was panting and moaning every now and then, calling his name, loving the way he was electrifying her body.

Through it all, Eric was the constant. She loved the way he was so relaxed, letting actual expressions replace his scowl. She especially loved the one he was making now as he thrust into her furiously and groaned like he couldn't help himself.

When he reached down and started playing with her clit again, Tris saw stars. He had only made a few shallow circles when the heat that had been building exploded. She cried out in surprise, calling for Eric because she didn't know what else to do. All her muscles tightened up and for a few long moments she was completely lost in the overwhelming bliss as her body relaxed and turned molten.

Eric's thrusts grew erratic and shallow and then suddenly stopped. She could feel him pulsing inside of her and she sighed, lost in bliss.

"How was that?" Eric asked breathlessly, a wide grin on his face. He pressed his lips to hers gently, then pulled away sharply, as if realizing what he had done.

"Good," Tris panted with a smile of her own.

She watched him as she came down from her high, his steely gaze so familiar as he looked down at her beneath him.

He looked cold. Disconnected from the moment, even though he was still inside her.

He also recovered first.

Tris let out a little whine when he pulled out of her, leaving her feeling empty.

But he didn't stop there. She wanted to reach out and pull him back into bed, but she knew that wouldn't go over well, so she stayed silent, still trying to catch her breath as he began to pull on his clothes.

She wasn't confused, just disappointed.

She knew he wouldn't stick around, but had hoped he would at least have waited until the sweat had cooled on their skin.

"Thank you," Tris told him as she watched him dress.

He looked surprised for a moment. Maybe he had expected her to complain about the distance he was putting between them. She knew better.

"You're welcome," he smirked, pulling his shirt over his head. "Was it everything you dreamed?"

"Yeah." She sat up, looking for her own shirt. Eric picked it up and held it out to her.

"You don't sound very enthusiastic," he noted as she put on her shirt, then searched the floor for her underwear.

She bit her lip, trying to decide whether to be honest or not.

"Maybe I didn't expect it to be over so soon."

He laughed, but didn't sound amused.

"You got your orgasm."

"Yeah. I did," she agreed, pulling her underwear up over her legs, ignoring the semen trailing down the inside of her thigh. "Are you leaving? I need to shower."

He was definitely surprised by that. Yes, he had expected her to be clingy and hard to get rid of.

"Yeah. I'm leaving."

"I'll show you out."

Hesitant because she was still dressed only in her shirt and underwear, Tris put on a brave face and led the way back to the living room, stopping to pick Eric's coat up off the floor on the way.

She handed it to him with a smile that she couldn't help. His hair was a mess from her fingers, his shirt untucked, and his skin was ruddy. Should he run into any of her neighbors on his way out, they would know exactly what he had been doing, but Tris couldn't bring herself to care. He looked gorgeous, as always, but more so because now she had this memory of him that no one could take away.

He didn't kiss her goodbye, nor had she expected him to, but he did linger in the doorway.

"I guess I'll see you on Monday."

"Yeah. Goodbye, Eric."
