Growing unfocused from the building pleasure, Athos leans back into Porthos’ hold, even as his hips jerk forward, betraying his greed for more. Everything is still so new, and he can only let himself be swept up in it all. He rests his head back against Porthos’ shoulder and tips his face against his neck, breathing in the scent of him, and then looking across at Aramis with an unsteady, breathless smile, carried by the tide. They have so many firsts ahead of them, and it’s as though his heart is full with every single one.
