Slowly she feels him begin to get harder, his prick filling out, until she can’t fit it all. Eventually he brings his other hand to her head as well and thrusts up into her mouth.

Hermione moans, feeling herself get wetter, and he finally mutters a finite at the hovering paper, which brushes past her as it folds itself neatly on the table.
