【Black Crystal】The chairperson is being bullied in class – slave declaration

An earnest committee chairman is bullied by his classmates and vows to become a slave.
Usually followed by a scene where the main erotic scene is set aside and the pledge to be a slave is made.
Slaves are divided into three levels, and each is made to swear to be [slave], [sex slave], or [masochist slave].
In addition, this series is not in chronological order, but rather the content of the theme is cut out for each situation, so you can enjoy it even if you don’t know the previous work.

This volume is a 32-page PDF file.
