Chapter 2

Again I don't own anything to do with AOT I only own this story and the OC's. So this is my first ever smut its not really as good as i wish it was but I cant really think of a way to write it better so... sorry. The next chapter will be on Levi and Freya so don't worry, and I'll try not to take so long. There is some kinky stuff in it and all but not too much yet (but the next chapter will be full of some kink). Oh and Rin is just the nick name that I gave the OC Karin. Well enjoy and please R&R. ^-^

Erwin's POV

Later that night after Karin made herself at home in my room a silence grew. While it is true I expected to be matched with someone within the corps I wasn't expecting to be matched with someone who I found appealing as well.

Her small size not effecting her womanly shape. In fact for her small stature of only 5'2" and her lean muscle frame her hips are still in a lovely hourglass shape and her breast full enough that they tend to bounce when she walks from one side of the room to the other in her constant pacing. The elephant of what we were paired up to do seemed to sit directly in front of us, and yet now that I know I can have her I c ant stop myself from wanting nothing mere than to ram into her.

"Okay…Okay, so we're partners, and we have a year in a half to have a baby." She states although it seemed she was saying it more to herself than to me. I was completely fine with the idea of her bearing my children. I knew she would be a good mother from how she treats her friend Freya, not to mention she shares the same love for knowledge as me.

"Yes, at least for the first one." I reminded her, the strongest 5% of the pairs where expected to have at least six children. A time limit only being set for the first. The image of her swelling with my child sent a wave of pride through me and I noticed the growing rod in my pants at the image. Yes, I would not mind her having my sons and daughters in the least.

Standing up I walk over to her to stop her pacing. I know that she would like time to get use to the idea before anything happened; however problems occurred and we did have a "deadline" to meet. And half of the time we were given will be spent with her already having conceived.

With my hands on her shoulders I can feel her tense before she quickly relaxes and leans back into my chest. 'good to know she isn't completely against the idea of being paired with me.'

Leaning down I brush my lips against the crest of her neck and shoulder, and in the process I am able to make out a slight gasp and moan from the action. Smirking against her skin I continue slowly. My hands sliding up her sides to cup her braless breast. Once she moved in she quickly changed into her sleep wear which consisted of nothing more than an over-sized t shirt which I fully plan on replacing with one of my own.

Her gasp echos though the room and I had almost no time to react as she turns around and attaches herself to my lips.

Erwin's rough hands on her breast were the breaking point. Karin couldn't ignore the ache between her legs any longer. Of course when she first realized that Erwin Smith was her partner she was in a state of shock but as she spent more time thinking about it he was actually really hot, yeah he was older than her but damn it all if his hands didn't make her want to rid his cock until nothing was left of her.

The commander's lips clashed against her's in a hungry need for passion and the need seemed to consume them both. Karin's hands traveled down his chest to remove his shirt and his movements mirrored her's. Both topless now he threw her on the bed that he was sitting on moments ago. He climbed over her and before she was even able to register what was going on his mouth latched onto my pearled nipple and bit down. She moaned at the feeling of his tongue run over her bud, as one of his skilled hands worked its way down to her underwear.

Erwin quickly took note of how drenched she was and a half smile soon appeared on his face.

"Someone is excited." His voice lowered slightly and Rin's was reduced to only responding in breathless moans. She was a virgin and never experience anything more than a kiss so just the idea of what she was feeling made her shiver with need.

Erwin's smile grew larger at the sound of her subconscious begging for him. Watching her face he inserted his middle finger into her wet hole. The way it felt wrapping around him he was forced to hold himself back from thrust into her to feel her velvet walls tighten around his length.

"Ah! Fuck." Rin could feel his finger in her searching for the button that would push her over while his mouth continued to abuse her breast. Withering against him she became nothing more than a bundle of moans and pleas.

"C-commander, Please I—Ah! Please I nee" Rin's begging falling short as the commander scraped his teeth across her aching nipple before letting it go with a distinct 'pop' to smile at her.

"What is it you need, Karin? You have to tell me for me to know" Of course Erwin already knew what it was her body was craving and yet the sound of her begging for him was too much for him to resist.

"I- I need you." Rin's face was now dusted with blush and she could feel a sinking feeling in the pit of her stomach from the humiliation yet the desire out weighted it. Erwin noticed how shy she appeared and came to the conclusion that he quiet enjoyed the look of his strong willed solider being bashful. Sliding his body down hers while pulling his finger out of her wet warmth caused a gasping moan to escape her lips.

Slowly the commander removed her underwear and spread her legs so that he could sit between them before placing his calloused thumb over her clit. A shocked gasp was her only response to the contact until she started to rub rough circles on the small bud breaking her will power even more. With his other had he spread her lips and traced the seam of her cunt with his finger before quickly sliding it in.

Rin's back arched at the recovered penetration and Erwin couldn't help but smile at the way her body pulled at his hand trying to pull it even further into her. Her wetness sliding over his hand as his slide a second finger into her caused his already throbbing member to become boarder line painful, but he wanted to hear those pleas from her again. He wanted her to crave him and beg him to ram his cock into her and impregnating her.

Regaining her composer slightly Rin started to buck against his hand. It want enough she needed more of him. She needed him deeper and faster.

Slowing down at her response Erwin knew how to get her to beg like he wanted. "Come now Karin, isn't this what you wanted" he asked curling both fingers inside her hitting her g-spot. Moaning out in delight Rin tried once more to rock against his hand to speed up his movements but the scout's commander was having none of it. Leaning down to speak in her ear Erwin told her, "What is it Karin? Could it be that these fingers aren't enough for that horny cunt of yours?" a moan was released and she again tried to push down on him but Erwin removed his hands completely to hold her at the waist to hold her in place. It didn't take long for the worked up red head to wither against him, and of all the responses that Erwin imagined he never once consider the possibility of her next line.

"DADDY! Please! Please daddy fuck me!" Everything seemed to come to a stop at that point. She had called him daddy and by the painful throbbing in his member, he liked it.

Taking the new development in strides the commander smirked and responded while rubbing just the tip of his seven inch cock against her opening wetting it.

"What was that, little girl?" His voice dropped and Karin could feel the walls of her cunt contracting just at the feel of him against her lips trying to suck him into her.

"Please daddy. I need you to fuck me." She had no time to process him moving over her before he was thrusting into her. The pain of her hymn ripping was present but she was so far gone that it was quickly replaced by the dull ache of her pleasure.

"YES! Ah—daddy yes right there" Rin was aware of the embarrassing things she was yelling out and yet she couldn't bring herself to care. He was stretching her open and with every movement she could feel the thickness of his cock twitch within her.

Her walls tightened around him in such a way that it made it almost impossible to move even with the amount of lubrication her body had made. Grunting in union with each other they both were aware of the cliff they both seemed to be heading for.

"Fuck Karin!' Erwin's thrust became more erotic and frantic as he gripped her thighs hard enough that there would be slight busing to lift her legs up between both there thrust. It only took a few more thrust of the commander's large member for Rin to scream out her pleasure while arching her back off of the bed. Feeling the constricting walls of her pussy Erwin gave a few more thrust before bottoming out of her and releasing hot jets of his cum in hopes of creating a child.

The feeling of being filled with cum setting off another wave of convolutions within Rin before finally she laid spent underneath the man who took her virginity making her a woman.

Erwin stayed within her to catch his breath, once he felt enough strength return to his arms he lifted himself off of the smaller woman and pulled out.

"Don't move for the rest of the night and stay on your back." It was a command but his tone left room open for her to deviate from it. Once he noticed her confused look he quickly clarified, "Laying still and on your back allows gravity to assist in the fertilization process, and you'll be more likely to get pregnant." Nodding in understanding Rin's face quickly turned red without the intense pleasure there to distract her from the humiliation. Smiling to himself Erwin decided it was quite pleasing to know that he could make her blush that shade of red.
