I Want to Defecate!

Shien-chan was enjoying the best feeling of openness with the wild feces secretly performed behind the school building. However, he was found by a junior boy and was in a hurry. How does Shien deceive this big pinch !? In the school toilet, in the room of the withdrawal sister, in an unidentified flying object ... 10 scat works and 2 other scat works drawn in various situations are recorded. Full of fainting scenes of heroines who woke up to the pleasure of defecation !!
