Just some smut that I needed to get out of my system. Yes there will be more, though chances are this won't be an actual story so much as just an excuse for shameless smut.

Rated 'M' for a reason (see the phrase "shameless smut" above if you're confused).

If you recognize it, it's not mine.

Hope you enjoy, leave me a review at the end please!

Eric opened the door to the training room late at night, having just returned from Erudite with Jeanine's warning still ringing unpleasantly in his ears. It made him want to punch something. So, he was going to punch something.

He was just getting ready to lay into one of the punching bags when the sound of heavy breathing stopped him, and he bit back a growl of frustration. Could he not just be alone for a while? What the hell? He was about ready to yell at the other person to fuck off when the rhythm of the breathing caught his attention, and a wide grin spread across his face. It sounded like someone was having a good time over in the alcove, or trying to anyway. He had to give them their props, if they were going to get busy in here, that was the place to do it. There were cameras all over the compound, but none of them had a view of that particular corner.

Of course, it also meant that it had to be initiates, because any member of Dauntless had the privacy of their apartment. He stalked over silently, grinning in anticipation of ruining someone's good time. Nothing better for a bad mood than interrupting horny teenagers.

As he got closer he could hear the breathing belonged to a girl. He also couldn't hear anyone else present, so clearly she was alone, whoever she was. He wondered who it was as he crept along the wall, inching toward the corner where he could peek over. Probably a Dauntless born, not many of the transfers would probably have figured out the cameras already. The idea of watching occurred to him, but he shoved it away quickly. He may be a bastard, but he wasn't a total lecher.

Finally he reached his vantage point, the tension in his muscles, his nervousness and his frustration with Jeanine all but evaporated as he prepared to get a serious laugh over some poor girl's humiliation.

Eric leaned around the corner just enough to see into the alcove, and his mouth dropped open in shock as he saw her, flat on her back with her eyes closed and pants around her knees.

The stiff. The fucking stiff was masturbating in the training room, in the middle of the night.

The shock held him in place long enough for him to notice something. Though her eyes were closed and she was breathing heavily, it was obvious she wasn't getting much of anything out of it. His eye caught on the movement of her wrist and the pose of her hand, and he realized she didn't really have a clue what the hell she was doing. Shit, it was probably the first time she had even tried, and she was probably going to give in to frustration and give up soon.

He knew he really should just walk away and leave her to it. He wasn't going to stop her, not now. As someone who masturbated on a very regular basis, he wasn't about to deny her the opportunity.

If it seemed like she was going to manage it.

Suddenly, a thought occurred to him, and he bit back a laugh as he thought of it. Obviously she had no experience with anything sexual, or her own body for that matter.

And what kind of man would he be if he didn't at least show her how to pleasure herself?

He knew his logic was lecherous and convoluted, but the idea of someone not knowing how, of never having the experience made him cringe. And really, it wasn't her fault. That damned faction of hers discouraged everything that had anything to do with yourself, and if anything would be considered selfish, it would be a good beat off at the end of the night.

Silently he crept toward her, thankful for his naturally light tread as he knelt down silently on the edge of the mat she was on. Now he was closer, he realized her problem. She was using just her index finger in a simple in and out motion. The poor girl hadn't even fallen upon the secret weapon that was guaranteed to give her what she needed.

Eric held his breath carefully, waiting for her to shift just the tiniest bit. After a few seconds she did, shifting her wrist to the side just enough.

Careful not to touch her anywhere else, Eric reached down between her legs and stroked the pad of his index finger across her clit.

Tris jumped a mile as her eyes flew open, and when they locked on him her cheeks burned crimson. She opened her mouth to speak, but nothing came out. He wasn't surprised either. What would one say in such a position, caught their first time by someone they loathed?

As much as he wanted to laugh at her expression, he bit it back. The only way he was going to avoid getting punched was if he came across as kind, or at least not ridiculing her.

"Shhh, Tris," he cooed softly, attempting to relax her. "Move your hand, I'll show you."

She stared at him with huge eyes and he tried to put a comforting smile on his face. After a moment, she moved her hand out of the way, and he moved his own into position, stroking and circling her clit with his middle finger.

Eric adjusted his position, laying down beside her as he continued to stroke her. It didn't take long for her to respond to his touch, for her hips to begin to lift upwards instinctively.

"There you go. It may be tiny, but trust me when I say your clit is the secret."

She watched him carefully, looking like she wanted to be confused but couldn't focus on anything but the pleasure he was invoking.

"And also, you're going to need more than one finger," he told her matter-of-factly as he let his hand slip down farther, sinking his first two fingers inside her in one deft stroke.

The sudden movement startled her, and she gasped in surprise at the sudden intrusion. Eric adjusted himself again, using his legs to flatten her own onto the floor and positioning himself half on top of her.

Very carefully, he placed the heel of his hand against her clit as he began pushing his fingers inside her, insuring that every stroke was still accentuated by a rub to her clit.

Tris's eyes had closed again, and her head tilted back as her mouth fell open. She moaned as her body began to spasm around his fingers, making him groan.

Unable to help himself, he leaned down and whispered directly in her ear. "You would feel so fucking great around my dick, you know that stiff?"

She let out another moan, louder this time in response and he picked up the pace, pushing her closer to the edge. Wincing slightly at the volume, he brought his face to hers.

"Just need to keep you a little quieter baby, don't need to be caught right now," he whispered as he lowered his mouth to hers in a kiss.

She was tentative at first, obviously she had no experience at all. Being from Abnegation, he wasn't surprised. He kissed her slowly, softly to let her catch on to the rhythm and motions.

He hooked his fingers slightly, searching out one particular spot with the calloused pads of his fingers. She let out a sharp cry when he found it, allowing him to slip his tongue into her mouth as she did.

He could feel her hovering right on the cusp, and with a deliberate movement of the heel of his hand and another quick stroke inside her she came, arching herself up into his hand as he covered her mouth with his to muffle the sound.

Her body shuddered as her orgasm washed through her, and he kept up a steady rhythm until he felt her quit spasming around his fingers. He slid his fingers out of her and lifted his mouth from hers in the same moment. While she was coming back to herself, he reached down and grasped the hem of her pajama bottoms, sliding them back in place to make her feel better. He was an asshole, but he didn't actually want to completely humiliate her.

If it were anyone else and it hadn't been painfully obvious it was their first time trying to pleasure themselves he wouldn't have been nearly as kind, but the idea of possibly putting her off ever wanting to again was more than enough motivation.

His erection was throbbing insistently, but he ignored it for the time being as he watched her.

"First time?" He asked softly. Her cheeks flamed red in response.

"Don't be embarrassed," Eric soothed, "everyone's got a first time."

"Why aren't you humiliating me or making fun of me?" She asked him warily. "I mean, I'm glad you're not but why? Why would you be… nice, I guess?"

"Because frankly, I feel like masturbating is something everyone should be able to enjoy. Originally that was exactly my intent, to come over here and humiliate the hell out of the poor bastard who picked the wrong place and time to have some fun."

Funnily enough, she relaxed then. It must have been because that sounded much more in character for him.

"But it was obvious pretty quickly that you didn't know what you were doing or how to please yourself. And the idea of someone not being able to made me feel bad, so I decided to help you out." He winked at her, making her blush again.

"Well there's got to be something in it for you Eric. Forgive me for not thinking you're quite that selfless."

This time he couldn't help the grin that spread across his face. "Didn't you notice?" He asked softly.

Her brow furrowed in confusion. "Notice what?"

Eric flexed his hips, pressing his erection firmly against her thigh. "Trust me when I say I enjoyed it very much."

Her eyebrows rose as she felt him against her, and some of the color drained from her cheeks.

"And how exactly does something that size fit?" She asked incredulously.

"Your body is designed to accommodate, within reason anyway." He wanted to laugh at her ignorance, but he knew that it wasn't a good idea right now. The last thing he wanted to do was push her off the subject of sex altogether, make her feel like it was something to be embarrassed about.

"So you're saying that," she gave his crotch a significant glance, "would fit inside me? Really?"

"That's exactly what I'm saying. And what's more, you would love it," he purred seductively.

"I still don't believe you."

Eric laughed aloud at her response, though he couldn't entirely blame her for the assumption.

"Do you need me to prove it?"

His voice was low and husky, and he saw her shiver slightly at his tone. If he hadn't been laying down already, the shock of her response would have knocked him over.

"And what if I do? Would you?"

Eric rolled fully on top of her and put his lips directly at her ear. "Over and over again."
