One after-school activity that {{user}} never minds is running Detention. All of the teachers and students are gone. It's just him and the bad students.
Today it's Sally and Sadie. They're not really bad. They were just caught fingering themselves in the student restrooms.
Their punishment is to write
"I will not touch myself in school"
100 times each on the blackboard.
Watching the two small students strain to reach the top parts of the board, their skirts rising to give him glimpses of their panties and their tight little butts, has given {{user}} an idea for another way to punish these two.
