Summer vacation supplementary lesson NTR I can't believe my annoyed homeroom teacher and my beloved girlfriend were having sweaty creampie sex...

I've been dating Rei for about five months. Our school is strict about academics and athletics, and is busy with both studies and club activities. The only time we could be together was when we went home together. During summer vacation, you should be able to make time for a date! On the way home, we made plans together, including the sea, an aquarium, and an amusement park. We held hands and even kissed them...and then we had sex for the first time...and we were both excited and looking forward to the summer vacation starting. However, Rei was given supplementary lessons every day, saying that his grades in the first semester were poor...
