The dull part-time jobber Tsutomu was supposed to work as a guard at the "Lustful Hidden Treasure Museum" on the verge of closing, but it was a treasure house that moved around as if a mannequin was alive at midnight! Because it's a treasure house, it's originally full of erotic lewd women! Spree with the vibes and rotors you see for the first time! Ejaculation management with super-dreadnought erotic succubus blowjob! Mannequins take off to prevent closing!
