A mouthful of cock does wonders when it comes to muffling irritated groans and preventing words of protest, yet as long as the duke's own hands are still free Athos' own will find no permanent resting place just there. Buckingham pauses in his duties immediately, and reaches up to drag the offending paw down to his shoulder. There. If you must.

...Now, strictly speaking such inconsideration deserves no reward, but as it just so happens Buckingham considers himself sworn to the spirit of immaculate performance, and could bear offering less, even if... it requires giving more than the stakes demand. If he should deem a mere back and forth with his head insufficient, and slowly pulls away because of it, lets the strokes of his hand take over as he cranes his neck and lets his tongue find Athos' balls, slick licks covering their entire surface, his lips sucking softly on wet skin.

Ah, what a true gift and a curse it is, to deem any job worth doing to the utmost of your skill. Any job. Any job at all...
