He can't help the pang of arousal at seeing Leon fall to his knees before him, his trousers soon undone and the man's lips on his skin. He certainly seems sure, though his intentions were never to humiliate him. He has a feeling that when Leon is clear-headed again he'll regret this- but he also knows how strong those aphrodisiacs can be in the moment.

"Not to worry, then. I will stay." And now that it's decided, and he knows what Leon wants, he feels better about letting this happen. His fingers tighten in Leon's hair and tug his head upwards to look at him, a small smile now on his lips.

"Put that mouth to good use, then." He's sure Leon will look good doing it. He runs his thumb across Leon's lower lip briefly, admiring the way he looks on his knees in the dim light, before letting go of him and resting his hands on his shoulders instead.
