Even through the haze of everything else, he remembers the things that M's told him; his touch is careful, gentle. It's not hesitant, but he is exploring Midnighter's length with a decent amount of his attention focused on where seems to do what, how much M seems to respond.

He shifts a little, sliding his fingers around in a feather-light sheath around Midnighter's cock before pumping it slow and steady: one, two, back and forth. His other hand shifts a little so he can get a handle on M's ass, squeeze it a little to hold him as he works.

Light, but not too slow. He's trying to do what he likes only... a little more. Hopefully, M's down for it.
