Caduceus felt the way Caleb tensed up after he spoke, and he was convinced for a moment that he had done something wrong, that he had been too rude, and an apology was on the tip of his tongue when Caleb pulled back. His words were cut off when fingers replaced his mouth, though, and a pleasured shiver ran through him. Through half-lidded eyes Caduceus watched as Caleb sucked on his fingers, the breath rushing from his lungs in a surprised moan at how beautiful the sight was.
He could just stare at Caleb forever and that would suit him perfectly.
This time he didn't tense up, too eager to have some relief. And the moment he felt the press inside him he moaned again, trying not to push down on Caleb's finger. The sensation of pressure along the underside of his cock made his vision white out for a second, a long, drawn out moan falling from his lips. It was tight now, he could feel the resistance against Caleb's finger, but he knew once he had everted fully there was more room. Room that had allowed him to rub at the sensitive base and stroke the sensitive walls that normally held him.
Without Caleb's hair to stroke, Caduceus resumed pulling at the soft padding beneath him, whimpering with every exhale. He could hear the slickness, too, and for some reason that added to the heat, to the dizzying pleasure of this.
"Caleb-" he rasped, the pressure mounting until he felt it break, crying out shamelessly as his cock slid out another inch, and again in another wave, almost completely emerged. Which was almost a shame, because Caleb's finger was driving him crazy, even if it had served most of it's purpose. "Don't stop." He really didn't mean to be so rude, or so demanding.
