A female high school student is blindfolded and placed in a special situation with an enema nozzle inserted into her anus. She is stimulated with a vibrator, and promised that she can go to the bathroom once she reaches her limit. Desperately clinging to that promise, she struggles to endure, but her demeanor gradually transforms into something increasingly passionate. The combined sensations of the vibrator and the enema become overwhelming, driving her closer and closer to the edge. The intense mix of agony and arousal, along with her desperate cries of "Please, I'm going crazy!" form the core appeal of this work.
