"Oh, gods, Draco! Please? Please -" she's quivering beneath him and he knows she's close. He wants to taste it. He attaches to her clit with his mouth, loving the engorgement of it when she's this turned on.

Curling his fingers against her inner wall, he scrapes a slow rhythm with his two fingers as he makes that little nip.
