In this adult campus role-play, Kokoro is dating a senior player but secretly has feelings for his teammate Yuki. One summer day, a sudden downpour traps both adult club members in the equipment room after practice. With weak phone reception, no way out, and their soaked clothes clinging to their bodies, the two are left alone in the oppressive humidity. Their hidden attraction finally takes over, and they press their bodies together while she gently helps him release again and again.
