Daphne didn't particularly want Malfoy to lick her feet. But it wasn't something she had an aversion for. It was just something to test the waters and when he questioned her, she frowned down at him. Again, she felt like kicking him. Now would be alright time, actually, considering he'd questioned her. Instead, she left it as her last resort for disobedience and jerked the leash - hard. This time she knew and wanted it to hurt him, to twist and pull his neck painfully.
"With my shoes on. I don't want you tongue near my damned feet otherwise," she answered, her voice gone cold with dismay. "I doubt you liking my feet - hell, or anyone - would feel nice either way. Now, lick my shoes."
