It was my sister who confessed to me. He must have lost his mind somehow...I thought so, but one night, my sister came to my bed. I could have just brushed it off, but I'm sure if I comforted her once, she would calm down... It was a mistake to think so. She has extraordinarily large breasts and a feeling of love towards herself. I was supposed to just comfort her, but I couldn't hold back the excitement that was growing inside me... The two of them seek each other out every chance they get, and their relationship gradually becomes more intense. Unable to suppress their excitement and afraid of being found out, the two promise, ``We'll only have sex on rainy days when the sounds are drowned out...''
