SACZ-391 Hina 1

A monitor that observes psychological state and behavior in situations where the toilet cannot be used. Hina Kawai has a hip size of 100 and a dynamite butt. It seems that they only urinate about three times a day, probably because they can store a large amount of water in their huge hips. Even so, when she is not allowed to use the toilet, she goes beyond her limits and ends up drenching the underwear that covers her big butt.
