Rough Sex - Chicago Fire - Matthew Casey x OFC

The ride home was unbearable. None of them saying anything to the other. Just a couple of hours earlier they were laughing and drinking with his team and now they weren't speaking. All because he thought she was flirting with Severide. She wasn't, by the way. Severide was actually just telling her of all the crazy calls he and Matt had responded to and the crazy ideas they had come up with for some of their rescues, but Matt thought differently.

They got home and that's when it began. Aria was already expecting it but she was really hoping that they would just go to sleep and talk about it tomorrow. No such luck, apparently.

- "Did you get set up a date before leaving, at least? I mean, I don't think I got there in time for that not to happen, so…" – He was pissed. Anger and jealousy dripping from every word. This was going to be a long night.

- "Oh, knock it off, Matt. He's your best friend. I was just being friendly. That's it."

- "Yeah, right. I saw the way he was looking at you. Checking you out. He definitely wanted more than to just be my 'best friend' to you."

- "So what? That doesn't mean he would get what he wanted. Or do you think I'm that type of person? Do you really believe I would cheat on you?"

- "I don't know. Would you?" – That stung. Now she was the one beyond pissed.

- "You know what? Maybe I should have set up a date with him. That way you would be right in accusing me of flirting with him and so much more. I wonder if he's good in bed? Maybe he'll give me a good fucking."

That was it. That was what send him over the edge. He didn't think about what he was doing; all he knew was that he was going to show her who was able to give her a good fucking.

He pushed her against the wall and kissed her. It was a kiss filled with anger, lust and jealousy. He was actually a bit surprised when she kissed him back. Picking her up by her legs, he carried her towards the couch, laying her there. He ripped her shirt open and pulled her jeans down, as well as her lacy panties. He could tell she was completely drenched. That just made him harder.

Taking his clothes off, he quickly got on top of her, aligning himself with her entrance. While kissing her, with a hard thrust, he was inside of her. "God, she feels so good.", he thought, grabbing her breast and licking her nipple, making her moan his name.

- "Let me show you what a good fucking is." – Aria wasn't expecting that, at all. He started thrusting, faster and harder than ever before.

- "Fuck, Matt. Don't stop."

- "You like it like this? Yeah? Say my name, come on."

- "Matt, fuck, Matt. Don't stop." – She didn't know what else to say. He was fucking her like he had never fucked her before. She couldn't think straight. Aria felt her orgasm climbing and soon she hit her peak. Screaming his name, she came, shaking violently under him.

- "Get on all fours." – She did as she was told. He thrusted inside her again, hard, slapping her ass at the same time. The feeling of him touching her core combined with the sting of the spank to her ass was taking her to new heights. She loved it when he was rough. A few hard and fast thrusts and they were both on the edge of coming.

- "God, Matt. Keep going. You're gonna make me come again."

- "Fuck, Aria. I'm almost there. Come for me, baby. Come on."

- "Matt, I'm coming. Come inside me, please. I wanna feel you come inside me. God, I'm almost the…"

With that, they both came. He could feel her cramping around his cock, sucking all of his cum into her. How he loved that feeling. Looking down at her, he could tell she was spent.

- "You okay, babe?"

- "I'm good. Just tired." – Aria answered, a tired smile on her lips.

Matt got up, went to the bathroom and brought a wet cloth. After cleaning both up, they just laid there, resting.

- "I'm sorry, Aria. But I really thought you were flirting and seeing the way he was looking at you, I just… I don't know. I'm sorry."

- "It's okay. I'm sorry too. But I gotta say, if this is the result of you being jealous, I'm gonna have to make you jealous more often."

- "Not funny." – He said, with a smile on his lips.

He would definitely repeat this, without the angry part. Definitely.
