Hinako takes her zentai sub and stuffs him inside a shiny rest sack and puts a Studio Gum latex mask over his head. Then, she slides him inside her giant, clear inflatable rest sack. She starts pumping in the air and his body becomes more crushed and compressed with every passing second until he is a vacuum-packed sub! Breathing is possible, but his lungs are compressed and he only has a small hole in the latex mask to breath out of. But Hinako, being the bully she is, takes even that away from him as she uses her big toe to plug up his only breath hole. She is so mean!
