MIMK-142 | RAIN - It was my sister who confessed to me - Original work: JACK-POT Jura Over 30,000 copies in circulation Live-action adaptation

It was my sister who confessed to me. She must have lost her mind... or so she thought, but one night, her sister came to her bed. She could have just brushed it off, but once she comforted her, she would calm down... She was wrong to think so. She has extraordinarily large breasts and a feeling of love for 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.
