A total of 66 T-back girls from both tournaments gathered at the pool and split into two teams, red and white, to hold an erotic battle on the water! They will do their best in T-back swimsuits for all events! They will slam their beautiful butts against each other in tough battles such as an underwater cosplay quick change competition and a T-back flag battle. The underwater camera "Dolphin Edition" follows the erotic happenings of swaying pubic hair and nipple slips as well as full exposure, and "We'll Show You the Whole Story" shows the sexual harassment and night-time indulgence that took place behind the scenes of the tournament. You can enjoy it three times more by changing the angle.
