Herself

Lost in perverse thought, Hermione doubles back into an empty classroom, breathing heavily. A torrent of sensual images flash through Hermione’s mind, each more lewd and kinky than the last. Just thinking about some of the things she could do with this spell is enough to get her dripping through her panties. In a rush to experience true sexual bliss before she cums from literal mental masturbation, she whips out her wand and casts a spell on herself.
