ビッチはじめました～特濃快楽の虜となった黒髪乙女、千百合～（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?

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.
