It was the most indescribably perfect thing Caleb had ever felt. He had been with men, and he had been with women. Or, well, one man and one woman. But this was altogether different from either. He could feel the walls of the sheath shuddering around him and the pulse of Caduceus' cock moving against his own and coaxing him closer towards his own end. Everything about it just rolled tightly together and burned through him. The way Caduceus looked, the way he sounded, the way he felt. He needed more of this. That was the only thought he had in those last few swift seconds.
His movements, though steady before, quickly became erratic. He didn't know how long he would have before Caduceus' cock began to retract again. Maybe he would still fit, even then, but he didn't want to risk it and he also didn't want this to stop. Whatever willpower he had been using to keep himself from hurtling over the edge finally dissolved and Caleb buried himself deep and let go. His whole body drew up tight - from his thighs, up his spine, to his shoulders - and for one blinding second he was utterly still and silent. Then a shudder rocked through him and he groaned, catching himself on one hand just before he collapsed forward.
He should have asked, he thought, if Caduceus wanted him to do that. But it was a little late now. Caleb shifted back to sit on his knees and nudged Caduceus' legs down again. For a moment he just sat there and panted - his face flushed, dazed, and more sedate than he had been in a very long time. His eyes had fallen closed in a way that looked almost serene. Or prayerful. And then he just ruined the soft image by drawing his hand up to his lips and licking it clean. He thought nothing of doing it, or of how it looked, it only mattered that he wanted to do it.
Sticky with sweat and completely exhausted, Caleb shifted to the side and finally collapsed on the cushions next to Caduceus. He nuzzled his shoulder and tipped his head up towards him, draping a leg across Caduceus' middle as he snuggled in against his side. He didn't want to leave this spot. Ever. He knew they would get kicked out eventually, but until other powers forced him from this comfortable nest, he had no intention of going anywhere.
