This summer was hot... When I returned to my girlfriend's hometown in the countryside for the first time in a while, Saki-onee-chan, who lives next door, called out to me. She had completely changed from the way we used to play together when we were little, and now she was exuding the sex appeal of an adult. While I was playing with my hands while reminiscing about the past, I touched the body of my girlfriend Saki-onee-chan, and I couldn't help it anymore and hugged her unconsciously.
