After debuting as a gravure idol and gaining attention through modeling, Saori finally takes on the hardcore Club Activities Diary series! The club she chooses is the track team. Training begins with simple stretching to loosen her hip joints. Viewed from below, a noticeable slit can be seen beneath her bloomers. But then the coach suddenly introduces an abnormal drill—forcing her to suck his balls into her mouth. He claims it's to increase lung capacity, but she clearly enjoys it, diving deep with enthusiastic deep throat. Even as she gags slightly, she never holds back.
Yet Saori's trials don't end here. Her erotic training is spotted by male students, escalating into further trouble. She's tied up by three men, including the coach, and subjected to relentless, lewd acts. With two dildos and a vibrator used on her at once, she orgasms repeatedly from overwhelming pleasure. Even past her limits, there's no mercy, no stopping.
The clubroom has long ceased to be a place of training, transforming instead into a den of perverts chasing pure pleasure. One creampie after another follows, pushing Saori's mental stability to the brink. What will become of her? The next developments are already highly anticipated!
