Synopsys:
Astral Express, once known as a train that traveled among the stars and galaxies now is become a sanctuary that filled by scent of lust. What was once a bright open longue where the Nameless can relax in comfort is now overtaken by a massive bed with dim light and smoke. The surroundings is now also filled by various things, such as sex toy and tentacles wiggling around.

At the center of this space, Himeko that is in horny condition, quietly straddled her Master's body. Even before ordered to serve her Master, she already prepared herself to be penetrated by her Master's cock.

It has been a while since the train arrived in new solar system. March 7th is now using her "Nameless" alias to recruit and train new followers (sex slaves) for her Master. "How long March 7th will bring new slaves for Master?" That question is making Himeko trembling with orgasmic sensation. Her body is shivered again on the verge of climax, however her Master stay slient. That silent order was all she needed to serve her master.

And so, a long lewd night aboard on Astral Express was about to begin.

===================================================================

Hello, this is the continuation of Ishi no Shita's HSR series, and for this one it's Himeko part. For next one probably I will take a couple weeks of break before continuing, because I'm currently working on something else.
Also, translator notes for 1st page:
"new females" is refering to new sex slaves, and
"her pets" is refering to the boys.

As always, if you have some feedback for the translation results or typesetting, feel free to tell me. Thank you and enjoy!
