Simon somehow got the penis to go down to 24 inches long and he could feel it deep in his bowels.
But in his fumbling with the controls he then made an accidental adjustment to his brothers balls.
They were growing huge.
Soon his brother was sitting on them like an exercise ball and still pounding simons ass harder than before.
