It is torturous, knowing that above him, Athos' head is tipped back in ecstasy and Aramis cannot see it. But just as Aramis can taste Athos now, pouring hot and liquid down his throat, Porthos can drink in the sight of him, and between them they will share everything. So he eagerly swallows until the jerk of Athos' hips has relented, pulling back to drop a kiss to the wet tip of his prick before he lays his head on Athos' thigh, head tipped to grin up at them as he gasps for air. His throat and lips are sore and swollen, and Aramis tongues at the corner of his mouth to savor the ache, saving the last of Athos' taste there for Porthos.
