[HOMA-136] To make sure my girlfriend doesn't find out... I spent a week secretly having cheating sex with a defenseless and bold naughty older sister Kyoka Tachibana (Censored)

<p>Her older sister looked nothing like her. Not just her looks, but especially her personality... I can&#39;t believe she&#39;s so boldly seducing me under 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 was 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&#39;s charms.</p>
