Story

Under the sweet-but-severe "cum control" of an adult woman, a typical young boy's sexual instincts are molded into subservience.

He wants to cum, he begs for her to free his aching balls, but mercy is denied......
Finally she rewards him, a week's worth of jizz rockets from his hole, the pleasure is unimaginably profound......
After an all-too-brief twelve minutes of bliss, comes the next punishment......
