Shishunki no Obenkyou – Episode 3 (EN)

Kaede Kasuga and Kobayashi were once close enough to visit each other's homes freely, but time and embarrassment drifted them apart. One morning, Kobayashi arrives at school just before the bell and bumps into Kaede. Overcome with shyness about walking together, he turns and flees the other way.

After school, Kobayashi is punished for tardiness with cleaning duty in the gym storage room—and somehow, Kaede ends up helping him. As they work and chat about old times, memories of their previous sexual encounter flood back, leaving Kobayashi flustered and eager to escape. He tries the door, only to find it locked—they're trapped inside.

The room grows stiflingly hot. Kobayashi removes his jacket, and Kaede follows suit. Her noticeably developed chest catches his eye, sending his heart racing uncontrollably. Trying to ignore the tension, Kaede confesses she's desperately holding in pee. Panicked yet resourceful, Kobayashi spots an empty plastic bottle and suggests she use it as a makeshift solution.

In the cramped, sweltering space, physical closeness and vulnerability blur the line between childhood friendship and budding desire. Will the situation lead to their first kiss—or something even more heated? This episode captures the awkward, erotic escalation of rekindled intimacy in adolescence.
