FNS-026 A track and field girl, Sawa Yamashita, repeatedly reaches intense climaxes drenched in sweat during a training camp while undergoing breast development training from the coach she hates

Sawa, who has come to the track and field team’s training camp, has long been growing increasingly dissatisfied with the coach, who is especially strict when it comes to training her boyfriend on the same team. Meanwhile, the coach, who had long had his eye on Sawa, offers her a special drink after practice. As her body gradually begins to feel warm, she finds herself unable to resist as the coach relentlessly teases her increasingly sensitive chest, and despite her feelings, she ends up reacting against her will.
