Sister Friend! – Adult PC Game

Synopsis

Due to my parents’ divorce, my sister and I have lived separately since middle school. I live with dad, she lives with mom.

But this summer, my father suddenly decided to renovate the house. As a result, I ended up moving in with my mother and sister on short notice.

I just saw my sister at New Year’s, so there’s no sense of emotional reunion… or so I thought. But now that we’re living together again after so long, my heart is strangely racing. (nervous sweat)

And here’s the thing—my mother will be away for work the entire summer while I’m staying here. “Just me and my sister for the whole summer?!” My imagination was running wild…

But then, three unfamiliar girls appear before me?!

“It’s not just us—my friends are staying over too.”

“Oh… I see…”

So it’s “my sister” + “three unknown girls” + “me”… under one roof… for one whole summer…

Actually… isn’t this even more erotic?!

A scenario where erotic happenings are inevitable—what happens next? (nervous sweat)
