イチャ姉！

Suddenly, my father decided to remarry.

As a result, I suddenly had four voluptuous older sisters in my life, with two step sisters in addition to the two blood-related sisters I already had... *sweat sweat sweat*

And one of those step sisters was a senpai I had a crush on in high school... And her older sister I had also done a lot of things with before we knew things would turn out like this...

Why is the world so small? *sweat sweat*

Before I knew it, we were living under the same roof, and my summer was engulfed by a tsunami of spicy, steamy, erotic daily happenings.
