Yuri isn't much of a morning person. He never has been, even when he was in training to become a knight. He's a night owl, much happier and more inclined to stay up late rather than get up early. He can get up and move quickly early in the morning, but if he has the time to waste, he would much prefer to stay in bed for awhile and doze in the early morning stillness.
Unfortunately for him, Flynn does like mornings. Yuri doesn't enjoy sleeping in the same bed as the blonde because he's like a little bird when he awakes, flitting around the room in a pointless haste.
It's early, too early to do them any good to rise yet. Yuri hates to be bored, and that's what he is when Flynn insists on getting up so soon. There's nowhere to go, nothing to do, and the waiting for other people to rise is less of a drag if he's still half-unconscious.
Sometimes, if Yuri manages to wake up before Flynn, he'll snake his arms around the other man's stomach and keep him pull close, not as some sort of comfort but just as a way to keep him from rising. Flynn inevitably wakes at Yuri's touch, and after fighting his grip briefly, Flynn rolls over so that their foreheads are barely touching. Yuri's eyes flutter open, and he plants a kiss on the blonde's forehead, then his nose, then his mouth, and Flynn returns the kiss with more energy than Yuri could possibly muster.
It isn't all that exciting, having sex this early. Flynn is always the one to top, and his familiar hands and fingers stir Yuri to wakefulness slowly. Yuri's movements are lazy, and he's content to let Flynn have his way. It's an almost dreamlike feeling when the knight sucks at his cock, his brain still hazy from sleep, and it's sort of nice, how the pleasure seems to fill up his whole body more than it normally does. Even in his still sleepy state, Yuri's hands and lips know their way around Flynn and stop at his sweet spots as they trace the lines of his body. Yuri's brain jars him awake at the flash of pain as Flynn's cock enters, but it's the good pain, and by the time he comes, Yuri is fully awake, fingers scraping at Flynn's hips as he thrusts.
Once Flynn too is finished, he heads off to the bathroom, fully prepared to start his day, and Yuri slides down into the sheets and curls up into a ball again, wishing he could fall back asleep. He can't, of course, and to be honest, he doesn't really mind that Flynn wakes up so early, not when it means they have time to do something like this.
