A guy is a chastity slave to a hot girl. The hot girl makes her go to the clinic once a week for training. One day he begs not to go but of course she makes him. She drops him off and then picks him up (the video doesnt show what happened), and he is completely obedient after. The clinic woman says she will send pics of his training. She gets home and laughs as he had to eat cum and do a bunch of other stuff (happy to come up with more things) and the video is all about how he has to go to this weekly training and that he knows not to push back or it will only get worse.
 
It's like...she doesn't want to have to train him she just wants him obedient.
