It was nearly impossibly hard for Isaac to keep his hands to himself, when Derek was so close.He knew that his hands didn't belong on his own body, bringing himself pleasure, they belonged on his Master. But Derek had given direction, and Isaac obeyed.
His fingers played up the skin of his thighs, tracing over the delicate weight of his balls, before cradling them against his palm. His other hand circled around the base of his cock, giving a quick squeeze, to try and calm him down. He was already so hard, and a small bead of precum teased at the tip of his cock. Isaac swiped his thumb over the head, and then slipped it between his lips, sucking it clean.
