Female teachers like it strong. Women who admire the "easy power" of being a teacher have an arrogant, instinctive desire to force someone to do something. The desire of a masochistic man who wants to "cum!!" is freely controlled by the ultimate teasing play known as "edging", and the hell of edging and abandonment are repeated. By "not letting him cum", the penis is straightened out, swollen to the brink of exploding, and as a reward, he ejaculates as much as he has held back, and then he is rewarded by drinking it all up in her mouth.
