A little mess (BATJOKES)

'Joker should argue about it more, should hesitate even a little, but the need was too overwhelming. He wasn't sure when Harley had picked Lily up, but he didn't oppose as it was handed towards him. Quite the opposite, a tiny whine leaving his lips as he nuzzled his skin against the fur. His cheeks flushed with embarrassment. He'd never quite been this open with Harley, despite all they've been through together.

It shouldn't be so easy for her to quell his worries either, with just a small coo. "That's it, baby." She boasts, and it shouldn't be her words of encouragement that spur him into falling harder. Faster.'
