A sadistic instructor at a slave retraining center gives a bad slave basic physical training. The instructor places the slave's hands on the table and climbs on the slave's back, making him move up and down, just like a rodeo. When the slave gets tired, the instructor hits him with a riding crop. Next, the instructor makes the slave do 100 push-ups. When the slave gets tired and his limbs start to tremble, the instructor hits the slave's legs with a riding crop, tramples on his hands with her high heels, and makes the slave do push-ups again. The instructor says that she is strengthening the slave's basic physical strength, but in fact she is using the slave to enjoy her own sadistic sexual tendencies.
