Porthos grins down fondly at Athos when he arches up, pins his gaze on him, and despite the fact that Aramis likes plenty well the feel of hands in his hair or scoring his back, this is about restraining Athos through it all. If anything, the look that Athos gives him only drives Porthos to hold onto him tighter than before, widening his knees to let Athos' body slip in between his trousers. He's the most clothed of the three of them, but hardly minds, given that every time Athos struggles, he gets some friction for it.

"Show him how deep you can take him," Porthos encourages in a growl, shifting his grip to Athos' wrists, now.
