General male and female monitoring AV. Limited to swimming team athletes. Female college students in competitive swimsuits challenge themselves with a fixed vibrator for flat swimming! DVMM-213

On the way home, they encountered female college students from the swimming club and introduced them to a specially set-up swimming pool studio! The female athletes, absolutely confident in their swimming abilities, participated in the "Fixed Vibrator Flat Swimming Challenge" with a high prize! They entered the pool and began flat swimming with a powerfully vibrating vibrator fixed inside their competitive swimsuits! Although they could normally swim a distance easily, the comfort of the vibrator caused their swimming style to break down, making it difficult for them to move forward and resulting in failure to finish the challenge! In the punishment game where a giant penis was immediately inserted into the water, the trained athletes underwent unprotected ejaculation into their vaginas!!
