"Glad you like," Marc said. Again, not that his own looks were ever something he gave much thought to. But that didn't mean it wasn't nice to know the person you were getting naked with enjoyed the view.

Marc appreciated Harley being prepared here because not like he'd had the foresight to bring something. (Also the awkwardness of having to ask to get some from Steven's stash if he'd had.) Plus her turning and reaching meant he was getting more of a view of Harley's back. So Marc showed his appreciation for both things by starting to kiss along what parts of her there he could reach.
