Amateur girls who were approached on the street were curious about the new diet machine, as they were being paid to be product monitors. This time, there were only girls with big breasts. They tried their best to hold on tightly to the new rodeo arm so as not to be thrown off, and their big breasts swayed as they were made to change into bikinis for the measurement! And when they got aroused by the electric massager on the arm, their panties were stained with it, even though they tried to hide it!
