The vibrator with a timer program is fixed to the girl's lower body, starting with vibrations at one- to two-minute intervals, gradually increasing the duration to five, six, and eventually ten minutes. As time progresses, her body tenses up more and more, drawing closer to the limit. A fixed camera captures the scene from a perfect angle, continuously recording the girls' helpless orgasms without interruption. The highlight of this work lies in its intense buildup of tension and pleasure, with the climax reactions surpassing the breaking point. A must-see is Kanon's orgasm scene, as she experiences overwhelming ecstasy so intense it triggers a panic-like urge to run to the toilet.
