We approached random college girls on the street and invited them to a special venue! They competed in the "Fixed Vibrator Domino Challenge" for a hefty prize of 1 million yen! The college girls, experiencing a vibrator for the first time, couldn't withstand the intense vibrations and climaxed one after another! Unable to complete the dominoes within the time limit, they were subjected to a penalty game where a large cock was forcefully inserted into their sensitive pussy, thrusting deep inside, making them squirm and climax repeatedly! The college girls' rationality was lost, and their pussies were finished off with an unapproved creampie!
