A new reverse shota series that perfectly suits the costume situation! The target is a beautiful F-cup woman working part-time as a costume mascot ♪ A precocious brat uses her position as a "little kid" to play naughty pranks and brain games! He puts a toy snake in her, hollows out her ass for a finger enema, and shoves a tail dildo in! She becomes a plaything at the mercy of the naughty brats... and has creampie sex while wearing the costume!
