Netorare climax guidance ~ Athletics girls are dyed in white

>Shizuku, who belongs to the track and field club as a scholarship student, has just started dating Toshiya, who is also a member of the track team, and they are new lovers. However, she is worried that her sprint times have not improved recently and that Toshiya is too shy to make a move on her.
>Then a new coach, a suspicious-looking man named Kurosaki, arrives on the scene. Despite his appearance, Kurosaki is a very skilled coach, and Shizuku's time, which had been slowing down, improves quickly.
>However, Kurosaki is really a playboy who takes advantage of the bodies of female athletes he has his eye on, and trains them in his lewd ways until they do his bidding! Starting with a minor body touch, Shizuku's body is gradually made more and more sensitive, and even her virginity is being violated.
