A training camp was held to strengthen the lower body of the track and field team. The coach gave passionate one-on-one guidance to the female members! During the regular air chair training, the female members endured with their thighs shaking. If they couldn't hold on any longer and fell, immediate insertion... However, as they reach the limit of their muscles and fall one by one, they become prey to the coaches' dicks. The coaches repeatedly perform intense piston-like movements to build stronger lower bodies. Finally, the female team members convulse and climax with their lower bodies. But the special training doesn't end here! At night, activate additional menus in the large public bath! Push your body to its limits with a bit of group sex amidst exhaustion!
