(R18) Sea Tentacle Show・水族館の触手ショー (Pixiv Fanbox)

A girl staff is randomly chosen to be displayed in the main lobby for a quarterly-held aquarium exhibition. She is placed on an inflatable shark floatie, unable to escape, held down by countless slimy tentacles. To make sure she's getting the proper attention, a floor guide is placed in front of her. Exhibition lasts for a full week, 10 hours a day.
