I became the manager of four girls on the track and field team... My harem club activities with four athletic girls with strong sexual desires ★ "Do I have to do everything...? Sweat"? Because... this is also an important part of the manager's job, isn't it? When we're practicing the crouching start or taking a shower, there are only girls around! Group club activities with four girls who are as interested in sex as they are ambitious are a dream world for any boy! "Manager! You have to manage everyone properly! We're all going to get stronger and become number one in Japan, right?"
