stein x reader smut

You have only been steins weapon partner for a couple of months now. You enjoy living with him, and helping with his experiments. But while you've been here the one thing you haven't been able to have, is sex. Your not the kind to want a relationship, but you're still alive. As a living being, you have the biological urge for sex, as stein would say.

Youve noticed his lingering glaces lately. It's not like you've made it easy to ignore you. Walking around in a t shirt and panties most of the time. But still he hasn't made a move, and your starting to get impatient. So tonight, you plan to jump him.

You start to walk through the lab in search of the stitched man. You find him at his desk, his mind absorbed in the screen so he doesn't see you yet. You walk slowly, with purpose to the man and spin his seat around to face you.

"What are you..?" He says before your lips crash into his. Your legs going around his to straddle him in the chair.

"Well stein" you say "what I really, really want right now is sex, and I was hoping you would indulge me."

The only answer he gives is a growl, as he grabbed your hips. You start kissing and biting down his neck. Trying to gain control in the situation he ruts up against you. A moan leaves both of your mouths.

Stein takes this moment to pick you up from the chair and set you on his desk. Brushing away the keyboard and papers. Grabbing the collar of his coat, you pull his mouth back to yours. His tongue licks your lip asking for permission. Which you plan to deny until he grinds into you again, causing a moan to slip from your lips. He takes this opportunity to slide his tongue into your mouth. You battle for dominance but you very quickly loose. So whole stein explores your mouth, you push his coat off.

You tug at his shirt, and he takes it off for you. But Stein decides you are far to clothed. Taking his scalpel, he cuts your shirt off.

"No bra, huh (y/n)?" He says, just heavy in his voice now. His large hands start kneading your breasts. Eliciting another moan from your lips. It suprises you because you never get this reaction when you touch yourself.

You close your eyes, enjoying the sensation. You hear a thud suddenly, looking through half lidded eyes you can see stein has removed his pants. Leaving him in only his boxers. You take a moment to appreciate his body. But he doesn't give you much time. He starts grinding into you again. You gasp, and grasp onto his shoulders. He sets a relentless pace, earning a few soft moans from himself.

You can feel the bubble in your stomach growing now. Just as you think it might burst he stops. You look up confused.

"I need you. Now." He says. Eyes filled with hunger. You shudder. Partly because your anxious for what's about to come, and partly of pride knowing that you did this to him.

He pulls your underwear off, and quickly drops his as well. You gasp in suprise. His penis is larger than you anticipated. Free from the confides of his boxers it now stands proudly at his stomach. But much like before he doesn't give you much time to admire it.

He slips on a condom before he positions himself at your entrance, and pushes in slowly. Allowing you time to adjust to his size. It hurts at first but soon that's replaced with pleasure. You grind up at him, signaling he can move now. And fuck did it feel great when he started to move. Pulling his shaft most of the way out before shoving it back in. You hear him groan into your neck.

Breathlessly you ask "please stein, faster." You think he might not have heard you but he obliges. Gripping your thigh for better support, he rams into you. You moan loudly, and he pulls your hair in response. Desperate for more friction. Your hand goes down to your clit and starts rubbing circles. You moan loudly again, resting your forehead on steins shoulder. You feel the bubble in your stomach start building again. You know you won't last much longer.

"Stein," you say. "About to.."

"Me too" he grunts

He feels your walls start to clench around him. You bite his shoulder, but he doesnt mind. He always did like a bit of pain. He watches as pleasure washes over your delicate features, and he keeps pounding watching you ride out your orgasm. But his thrust are getting sloppy. You are very tired after your orgasm, but hold out for steins. You feel his member twitch inside of you, with one more thrust he stops. Riding out the waves of his own orgasm. His head resting on you. After a few seconds he pulls out of you. Removing the condom before tying it and throwing it away. Both of you still breathing heavy.

He looks up at you and says "maybe we should do that more often."

You laugh lightly and respond "yeah I think I'd like that"
