Đánh đòn đít bằng cách dạy tiếng Anh - phiên bản dài đầy đủ

Today, my colleague and I have an English lesson. He is not a very diligent student, so spanking on the ass comes next. First, I handcuff his hands tightly behind his back and he has to be in the position I determine and wait for the spanking on his ass. Then we have an English conversation and he also has to count butt shots.
