Bitch Hajimemashita ~Tokunou Kairaku no Toriko to Natta Kurokami Otome, Chiyuri~

Chiyuri's new friend Misae has swept her up into a life of decadent spending. A shy and serious girl by nature, Chiyuri's never had a friend like this, and doesn't want to let her slip away just because of money problems. She's heard that a girl can make quick cash doing just one night's work as an escort.

It's a slippery slope. But Chiyuri is curious, and she wants the money.

Everyone does escort dating these days. Why not her?

When Chiyuri has to decline her friend's travel invitation, she enters the forbidden world of escort dating. It will just be this one time, she promises herself, but a date rape drug opens her legs... and her eyes. The doors of pleasure are thrown wide.

Now Chiyuri is chasing that pleasure. She fucks everywhere and everyone!
During karaoke! With groups of men in love hotels! In public! For free!
She drags Misae into the dark world, and can't get enough.
