Amateur Girls VS Machine Vibrators, the 4th installment, targets female college students in a spring campaign! A magic mirror studio is set up in a super cheap izakaya, and the machine is inserted into the girls' guards, which have been loosened by the power of alcohol and money, and the girls are immediately thrusted in! Once they get on top of each other, the female college students are mesmerized by the thrusts that are more powerful than their boyfriends, and they squirt everywhere! Their vaginas are so sensitive that they can't refuse the insertion of a meat stick!
