Hermione Granger, the brains behind the brawn of the Harry Potter trio, finds her Gryffindor house robe tented one night in the common room. She's curious, hungry, and alone. She pulls out her wand, not for charms, but to summon a porny patronus - a massive, throbbing cock. She gasps, her pussy dripping with lust. She spreads her legs, her fingers dancing on her clit, then plunging into her untouched cunt. She moans, her body writhing as she fucks herself, her eyes locked onto the cartoon cock, wishing it was filling her up.
