A sudden storm soaked a student's clothes, making it impossible for them to go home... The two were alone at school, and as their homeroom teacher, I irresponsibly ejaculated inside them until morning. (Nana Hisaki MIAA-708)

Student Nana Hisaki is stranded due to a sudden storm. Her developing breasts are soaked through, incredibly lewd... Her A-cup breasts are visible through her wet, see-through shirt. How could I possibly resist? We're the only two of us alone at school... Her sensitive, soaked breasts and immature body give me a complete erection. It's all the rain's fault. Then, abandoning my responsibilities as a teacher, I begin a day of repeatedly taking responsibility for her and ejaculating inside her.
