Both dressed in custom-made form fitting neck-entry latex catsuits from Fantastic Rubber, Hinako and her sub put on gas masks and connect them via rubber tube. It is a very romantic sight to see Hinako’s sub only able to breathe Hinako’s breath and nothing else. After that, they tried something else and mixed their breath together. The whole ordeal was excruciating and they could not do this for long, but they were laughing and having fun the whole time.
