Best friends compete in three rounds of an exercise game! They can't go home until they reach 1000 points with the fixed dildo! The first person to reach the goal wins a prize! They insert the fixed dildo themselves and compete in an embarrassing hip-shaking contest! The Amateur girls were reluctant at first, but they climaxed in succession from the number of hip-shaking moves they had never experienced before! Some even squirted! The penalty game was to shake their hips 1000 times more than the remaining number of times with the AV actor!
