MIRD-154 I became the manager of the girls' track and field team.

I became the manager of four girls in the women's track and field team... A harem club activity with four athletic girls who have strong sex drives ★ "Do I have to do it all...? Sweat"? Because... this is also an important part of a manager's job, right? Whether during crouching start practice or in the shower, everyone around me is female! Group club activities with four girls who are just as interested in sex as they are in improving their skills are literally a dream world for guys! "Manager! Make sure you manage everyone properly! We're all going to get stronger and become number one in Japan!"
