The sound that tears from Aramis' throat is very nearly a sob, and it's as if his body has been waiting, happy to be the instrument by which Porthos fucks Athos, but now he has permission to fall apart. Orgasm curls deep in his belly almost at once, and Aramis opens his eyes to stare down at Athos, shuddering as he begins to spend deep within him. Even as it overtakes him, Porthos' cock nudges at that sweet place within his own body, and Aramis' sobs become real, his face pressed to Athos' throat as if to hide from the intensity of his pleasure.
