Len's brows furrow as his lips are captured with something hungry and desperate. He'll push back into it, tilting his head and giving his all until Mick mutters those words against his lips. He keeps kissing him, feeling like his lungs are burning, not just from the lack of oxygen but the heat of Mick's mouth and tongue ravishing his own.

"You...need to rest." He manages breathlessly, blue eyes looking into those dark, heated pits. He's wanted this for some time and as far as opportunity goes this is the best even if Mick needs time to recover. Maybe if he wears him out he can sleep better. Give his mind something good to latch onto. So despite his own words, or the way he hesitates briefly, fighting with himself and wanting to be selfish, he'll dive right back in, cupping Micks face as he consumes him.
