In a cosplay room, Mary Saotome, dressed as Kakegurui, alone and eager, lubes up her massive butt plug. She teases her tattooed skin, pushing the plug's tip against her tight anus, gasping as it breaches her rim. Slowly, she works the plug deeper, her ass swallowing the toy inch by inch until it's fully seated, her pussy dripping with excitement. She fingers herself, moaning, her cosplay costume riding up, exposing her glistening cunt and plug-filled ass.
