HOMA-136 So she absolutely wouldn't find out... I spent a week secretly having hidden affairs with that carefree and boldly perverted older sister. Kyoka Tachibana.

Her older sister looked nothing like her. Not only her appearance, but especially her personality... how could she so boldly seduce me in the guise of a kind older sister who cares for her younger sister! I was only thinking about my sister. There was no way I could hold back, and once we had sex, I kept doing naughty things with my older sister, stealing her eyes. The more I thought about it, the better it felt, and I became more and more captivated by the older sister's charms.
