Sometimes, it doesn't take a lot. Just one brush up the thigh, letting his long hair fall over the other man's shoulder, his shirt drawn down just a little more than usual, and Flynn wants it, wants it now. It makes Yuri proud to see how easily he can make Flynn succumb and want him.
Sex in Flynn's office is especially fun, and God only knows it doesn't take much at all to persuade Flynn to take him over his desk even as it's littered with unfinished paperwork. The surface is hard, and it's cold as Yuri gets shoved onto his back with his legs spread apart and his fingers grasping at whatever he can reach, eventually falling on Flynn's hair. He can feel the corners of paper ripping as he twists under Flynn's hands, and he knows there will be hell to pay when Flynn realizes his work is getting torn.
But for right now, it's nothing but pleasure, sweet pleasure in his whole body as Flynn's fingers fumble with the buttons on his shirt and strip it down his shoulders, his face nuzzling up into Yuri's throat and his hands raking down his sides. Yuri leans his head back as a moan escapes him and uses his fingers, still twisted into the other man's hair, to drag his head down, down, down.
Flynn takes him without complaint in word or in expression. He's eager, almost, as he licks at the hardened cock, and his cheeks hollow as he takes all of Yuri in. Yuri is more than content to lie back and take it. Flynn is always like this when he's exhausted by work; instead of getting tired, he gains a manic fervor that doesn't pass until all work is completed, and Yuri is his smoke break.
When Flynn finally pulls away, a small strand still connecting him to Yuri, the long haired man has only a few seconds to breathe before he is hoisted up and entered. He groans and stiffens, and it's tight, always tight no matter how Yuri thinks he's used to it. But it's not a pain he minds, and the quiet groan in Flynn's throat makes him even gladder it's tight.
And when Flynn is finished and out, Yuri pulls him into an embrace and a kiss, less from affection and more from a vain hope the blonde won't be angry about his torn papers.
He is, of course. Yuri doesn't really mind though, and he makes his escape from Flynn's office with a wink and a very sarcastic blown kiss.
