While working, Hikari-senpai rushed in. It turned out that she had forgotten something so she went to get it. While leaving, the rain was so heavy that her whole body was soaked. So we're both stuck here together. The thin wet shirt clung tightly to her body, revealing her pink white skin and sexy black underwear. While watching, thunder suddenly sounded, Hikari-senpai hugged me tightly! The scent of her body and her smooth skin coming into contact with mine made my mind seem blank. I couldn't control myself and vigorously inhaled this scent, touching all the seductive curves of senpai's body. When I regained my composure, I realized what I did was extremely wrong. Just as I was about to stop, Hikari-senpai changed again. She was no longer resisting and shy like before, but she even took the initiative to proposition me! And then we made love all night long, our bodies drenched in sweat and rainwater mixed together until the next morning...
