Merlin's slender fingers wrap around Damien's massive, black combat boots, his heart pounding with anticipation. He leans in, his tongue darting out to spit on the toe, his eyes locked onto Damien's, seeking approval. Damien nods, his voice a low rumble, "Clean them thoroughly, boy." Merlin complies, his hands rubbing the spit into the leather, his tongue tracing the laces, his body trembling with excitement as he serves his dominant master.
