Bondage of this magnitude are why people come to best. Hinako is very meticulous in her bondage rigging. In this scene, she has her sub in a latex cat suit and canvas straitjacket. She lays him down on the bed and uses tape to affix his whole body to the bed. Being the meticulous rigger she is, she makes extra certain that there is no way he can squirm or wiggle away from the Hitachi-ing she is about to inflict on him.
