All Pent Up (Eustass Kid X Reader)

"Kid?"

You walked into the room to see your lover sitting with his back to you, goggles pulled over his eyes as he tinkered with something at his desk. The sound of metal clinking and his mechanical arm whirring continued uninterrupted, telling you he had yet to notice your presence. A wry smile rose on your lips, remembering the first time you had entered only to be met with his fierce glare.

Quietly, you strode over to where he was seated and pressed yourself against the back of his chair. He gave a small hum as you draped your arms over his bare shoulders, gently caressing his face and pressing a kiss to his cheek, but never averted his attention from the metalwork in his hands. You sighed with contentment, feeling his skin against yours and secretly enjoyed the fact that he did not shy away from your touch.

"It's late," you stated softly, letting one hand wander along the line of his collarbone as you rested your chin on his shoulder, "you should get to bed soon."

He grunted absently in response, earning a small, resigned smile from you. It had been a while since he had slept in the same bed, being too engrossed in whatever new project he was working on to give you any attention. It wasn't so much that his lack of attention annoyed you as much as it made certain desires well up and you knew that you couldn't very well manage to satisfy them yourself.

"If you come to bed, maybe we could have some fun before we sleep," you whispered into his ear in a sultry tone, kissing up his neck and nibbling at his earlobe in an effort to grab his attention.

However, despite your efforts, he merely grunted once again and continued with his work. You frowned, frustrated in more ways than one and lifted yourself from his back. Feeling the weight of your arms disappear from his shoulders, Kid looked up from his work and gave his surroundings a cursory glance. He gave a small hum when he saw you weren't there, thinking that, like the nights before, you had given up and gone to bed by yourself. Rolling his shoulders to get rid of the tension, he was about to return to the object in his hands when he felt a tugging at his waist.

"What the -- "

He looked down to see you kneeling underneath his desk, hands wrapping around his exposed cock before he could utter a word. You looked up at him as you trailed one hand along his length, eyes meeting his, and grinned.

"Finally caught your attention, did I?" you cooed from between his thighs.

Bewildered, he took a moment to realize what was going on before his lips twisted into a smirk. "Well, this is one Hell of a way of doing it," he grunted, lifting the goggles from his eyes.

Giving him a smug smile in response, you rubbed the tip of his member against your tongue and watched as a shiver ran up his spine. You giggled at how his cock stood so eagerly and trembled under your touch.

"All pent up, are we?" you said with a laugh, the warm air from your lips causing him to bite his lip. "It wouldn't do to have you finish so quickly; we're just getting started."

His eyebrow twitched in annoyance. "Who said I was finishing?" he retorted indignantly, trying to sound dangerous but being betrayed by the hint of arousal in his voice.

"With the way this is reacting, I'd say you will be soon," you stated simply, placing a soft kiss along the shaft before running along the underside with your tongue.

He opened his mouth to say something, but was stopped, a low fuck escaping his lips as you slipped him into your mouth, the warmth and wetness almost sending him over the edge right then and there. He grit his teeth and tangled the fingers of his right hand in your hair, watching as you slid his member in and out of your mouth, sucking just enough to make him want to buck his hips for more.
