Aramis can feel Porthos' hands tremble where they hold him down, and he knows as soon as Porthos descends again that he cannot last. He means to hold out and enjoy this, but Porthos' mouth is too sweet, and Aramis wants deep in his bones to spend inside of it. "Cariño," he warns, body beginning to seize as the pleasure coils, "Oh, you will undo me." He manages to get his fingers back in Porthos' curls, hand curled reverently against the back of Porthos' skull as he spends and moans.
