Nothing Gentle (Casey x The Beast)

Rough

Before she could even realize what was happening, and with power and speed she should have expected from him,he flipped her over,positioning her in all fours as he nudged her legs apart and settled himself between them. The shriek in surprise she let out turned into a moan in pleasure and pain equally, as he entered her, filling her to the brim. She was sure, along with the rest of his body,his cock grew bigger too, she could feel it. He started moving then, burying himself deeper into her with each thrust. He didn't start off slow, but rather pushed in and out of her with a vigor she was experiencing for the first time with Kevin's body.

 She had never been like this with Kevin, or even Dennis, or Barry. Whenever she was with them they made sure not to do anything that would hurt her, they handled her as if she was a fragile flower they might crush if they applied too much pressure on. The Beast, however, was entirely different. She should have expected it. He wasn't human, he wouldn't think like one when being with her. He wouldn't care if he hurt her, he would only focus on quenching the thirst he felt, obey to the call of the flesh, the pure,  animalistic instinct of reproduction. Just like an animal. Casey wasn't sure she minded.

It should disgust her, though, she thought, but instead she found herself moaning louder with each deep thrust of his inside of her, clutching the headrest of the bed for support. He swiped her long dark hair on one side of her neck to lick, suck and bite down on the skin of her neck, shoulder and back. She bit her lip as she thought that this would surely leave a mark after they finished, along with bruises on her hips in the shape of his fingers. He moved one hand to squeeze her left breast hard and toy with her nipple, her face held up with his other strong hand around her throat, squeezing a little too hard as he continued pounding in and out of her, all the while letting low, inhumane growls out of his chest.

There was nothing gentle or tender in what they were doing, it was nothing like when she was with the others,full of love, sweetness and appreciation for each other. This was rough, dirty fucking that would leave her raw in the aftermath, but she was so turned on and wet, and her head was spinning, and he felt so damn good inside of her, that she thought she didn't really mind.

When he felt she was close to the edge, he brought the hand that kneaded her breast before at her front, and with two rough fingers he started forcefully rubbing her clit in quick circles. That caused her to cry out loud and roll her own hips back against him. His ministrations, combined with his heavy breathing against her ear and the sound of slapping skin against skin made, had her come hard, clamping down on him with a high pitched, breathy cry. As a result, his own orgasm was triggered and she felt him release his hot seed deep inside her with a loud, guttural growl coming from deep inside his chest.

As they came down from their highs, he leaned against her, his chest against her back, his head resting on her shoulder, both of them breathing heavily. Then, he pulled out of her, lied down on the bed and, unexpectedly, he hooked one strong arm around her waist and pulled her against him, nuzzling his face in her hair almost immediately falling asleep, his breathing even now. Too tired to analyze the situation, Casey soon felt her eyelids starting to droop, eventually falling in a deep, dreamless sleep.

A/N: Sooo,this is it, folks! This story is the first smut I ever attempt to write,so Idk if it's good, but this is just the beginning, I'm going to be writing lots of smutty stories because I love reading them, and I most definitely enjoyed writing this one! I really hope Casey and the Beast were into character and not too OC, I really tried hard to make it happen. I don't know if Barry is supposed to be gay in the movies, but I really wanted him too to have something with Casey,so Idk. As always, opinions and constructive criticism are always welcome, I hope you enjoyed!
