The Prince knew Riku enough by now that a little sore could mean a reasonable amount of pain. Sora didn't know how a Prince was supposed to properly dismiss a lover in the morning, or what he was supposed to do after he deflowered someone. So Sora decided to act as he thought a proper husband might act instead, not as a Prince who took whatever body in his bed he liked.
"Stay comfortable, my love," he told Riku, pushing off the covers and crawling over Riku to kiss his face affectionately. "I will ask for tea." Brunch would be soon, so just tea was good.
The Prince practically bounded out of bed, filled with energy, and skittered around the room looking for a robe. He shrugged it on and plucked their cat off the floor, scratching her ears before he opened his door to find a guard.
