When I setup an illegal brothel the first applicants were my step mother and sister

20 years ago, when I was still in elementary school there was an elder girl that I loved.
She was like a strong and kind sister that looked after me in place of my sick mother...

A few years pass, my mother passed away and my father remarried...
... to that elder girl. The girl I loved...

Some more time passed and a child was born between the two of them...
Unable to hand it anymore, I fled from home... and ended up as the scum of society.

I've just opened up an illegal brothel and... look who came as the first applicants.
My step mother, the girl I loved... her daughter = my half sister...

Well, well, well... what shall I do with this delicious turn of fate...
