Artist's commentary
Behind the school building, the student council leaves secretary-chan with a vibrator.
This is a system, that requires the user to spread out their hips, so their skirt doesn't come off, while the fixed vibrator goes in deeper and the tight ropes forces the user to orgasm like crazy.
The student council found out about secretary-chan's love for masochism, which lead to the start of a new (pleasureful) hellish new daily routine.
