Adolescent Studies Episode 3: The Age When You Want to Try Kissing

Story

Kobayashi and Kasuga used to visit each other's houses, but as time passed that stopped. One morning, Kobayashi arrives at school right on the edge of being late and runs smack into Kasuga there. Though she called out to him, Kobayashi felt embarrassed about going to school together and turned back the way he'd come as if to flee. After school, Kobayashi ends up cleaning the P.E. storeroom as punishment for being late. Somehow, by the flow of things, Kasuga is made to do it with him too. When the work reached a stopping point, they were reminiscing about the old days, but Kobayashi remembers that he and Kasuga had had sex and it gets awkward. He tries to step outside for the time being, but the door won't open. The two of them are locked inside the P.E. storeroom. It's hot inside, and Kobayashi takes off his jacket. Seeing that, Kasuga takes off her jacket too. Kobayashi can't stop his heart pounding at how utterly different Kasuga's chest is from before. Oblivious to what's going on in his mind, Kasuga confesses that she's holding in her pee. Hearing that, Kobayashi feels he has to do something, and looks at the plastic bottle in his hand.
