"I would be offended if it were not true," Sirius agreed with a chuckle and leaned down to nuzzle at her neck. "It's much more enjoyable though, I admit." He nipped playfully at her neck before pressing a soft kiss to it. Although he thoroughly enjoyed leaving marks, he wasn't quite sure her feelings on the subject just yet. Though, with that nip to his neck, perhaps she was more open to it than he'd have imagined.

"Mm, eventually... I would hate for you to disappoint dear Professor Slughorn," he murmured while pressing a series of kisses along her jaw before lifting his head and looking at her with a warm smile.
