KANADE was secretly working overseas as a spy, but after making a small mistake she was sent back to Japan for a re-education program. Her weakness was that when she received too much sexual stimulation, she would have intense orgasms and would lose control. In order to quickly correct this, the skilled instructors used any means necessary to subject her to lewd training, but... the woman's reactions were so good and her writhing was so lewd that even the instructors lost their senses in excitement and became immersed in the endless sexual torture, driven by their swelling sexual desires!!
