When Hinako first received this rest sack from one of her subs via her Amazon wish list, she did not really know how to use it. With this rest sack, it is impossible to outstretch the legs. She and her sub both thought about it and they eventually came up with a plan. So, she put him in a canvas straitjacket, then into the rest sack and then wrapped the whole thing up. He was completely immobile, and Hinako was starting to have some fun. She continued, taping the Hitachi to his dick with vinyl tape and shoving her bare feet into his face, him to smell her horribly stinky feet.
