Asian Goddess Seira – Treatment for small cock and balls

I am unhappy with My slave’s small cock and balls, so I take him in for some treatment. I try general pulling to stretch his balls out. But I realize that it is probably the easiest way to make his small cock and balls bigger is just to beat them. I try various methods of beating his cock and balls; kicking his balls, cock slapping, squeezing, punching, ball stretching, ball stomping.
