It was probably a good thing that Caduceus enjoyed having his ears played with as much as he did because Caleb was absolutely obsessed with them. Any little difference between the two of them instantly drew his attention and became something he was endlessly eager to explore. There were a lot of them, too. Not just the most obvious superficial differences like the structure of their bodies or the soft fur the covered Caduceus' skin, there were these little hidden things that Caleb was slowly discovering as he explored. Different things made Caduceus groan and purr. The rumble in his chest when he spoke with intention was different than anything Caleb had felt before. His hands felt different. Even his lips felt different. And Caleb loved all of it.
But right now it was hard to focus on much other than the way Caduceus felt inside him. Each sudden jolt and press up into him dragged out another heavy moan. As the pressure and heat built, so did the desperation to feel more - to feel all of him resting there. He ached, but he refused to reach down and touch himself, instead trying to find a little bit of friction where he rubbed up against Caduceus' stomach and left a trail of slick fur behind. That desperation didn't abate any when Caduceus pulled him in for a warm hug, but he did pause briefly to cuddle down into him and bury his face against his neck. He could still touch here, and he did, running his hands along Caduceus' shoulders and down his arms, then sliding back around to brush his fingers over his ribs and up his chest. He just wanted to keep touching, always.
He shifted back up again, going still just to feel the heat pressing up into it. His hands settled on Caduceus' chest again and he drew his nails softly through the fur to brush over both pale nipples at once. Endlessly curious, he wanted to see what kind of reaction that would have. He was delighted by Caduceus' face too - the looks of encouragement and arousal all mixing together there.
"Bren," he said, just now catching that Caduceus had slipped into the other name again. It was nice, though, knowing that he had such an effect on him that he'd already forgotten. Or just got caught up in what was more familiar. He emphasized the word by rolling his thumbs over Caduceus' nipples, then circling the skin around them with his nails. Just a little tease. Enough to draw his attention.
Then Caleb's hands moved again, one sliding back up into Caduceus' hair and to his ears to scratch and rub again, while the other slid down between their bodies, past Caleb's own ignored cock, seeking out the spot where their bodies came together. He rubbed at the sheath with the back of his fingers as he pressed up, rubbing against himself and Caduceus all at once, trying to see if he could slip a finger inside with him. He just wanted more and he wanted it all at once, but he could stretch himself out a bit more just to make sure he was ready for the next press inward. It was deliriously good, too, and he caught himself gripping Caduceus' hair as he got one finger in, his knuckles still rubbing against the sheath as he curled and stretched.
