Derek smiled as he milked Isaac's cock, coaxing him through the orgasm and the aftermath. He kept his mouth close, alternating between filthy tongue kisses and chaste presses of lips against skin. Sated, and pleased now that his slave was also pleased, the werewolf let out a low, pleased rumble. He wiped his hands on his shirt, then used the hem to clean up the boy before he stripped it from Isaac's skin, leaving him bare once more.
"Always so good for me," he mumbled, and dropped another kiss against the boy's temple as he cradled the long, lean body against his own.
