サディスティックな女教官が奴隷の背中に乗って奴隷の基本体力を強化しながらロデオを楽しむ

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.
